WITNESSES AT HEARINGS ON APPEAL Appellant and his wife ATTORNEY FOR THE BOARD L. M. Barnard, Counsel INTRODUCTION The veteran served on active duty from June 1966 to June 1969; he served in the Republic of Vietnam from May 30, 1967 to May 21, 1968. This appeal arises from a December 1990 rating decision of the Pittsburgh, Pennsylvania, Department of Veterans Affairs (VA), Regional Office (RO), which denied entitlement to the benefits sought. In June 1991, a rating action was issued which denied entitlement to individual unemployability. In January 1992, the veteran and his wife testified at a personal hearing conducted at the RO. Following this hearing, a rating action was issued in May 1992 which denied entitlement to the benefits sought. In September 1992, a hearing was conducted before a member of a Board section. Following this hearing, the case was remanded in July 1993 for further development. A rating action was subsequently issued in April 1994, which confirmed and continued the denials. Another hearing was held before a member of the Board in September 1994. In reviewing the record, it has been noted that the veteran appears to be raising a claim for entitlement to service connection for a cervical spine disability, as well a claim that clear and unmistakable error was committed when the RO failed to assign a compensable evaluation for his right knee injury residuals between 1969 and 1980. However, as these issues have not been properly developed for appellate review, and are not inextricably intertwined with an issue on appeal, they are hereby referred to the RO for appropriate action. CONTENTIONS OF APPELLANT ON APPEAL The veteran contends, in essence, that service connection should be granted for a skin disorder, retained foreign bodies in the right elbow and for the residuals of trauma to the right eye. He asserts that he was exposed to Agent Orange while serving in Vietnam, and that he has had skin problems ever since. He states that he suffered shrapnel fragment wounds in the right elbow when an explosion destroyed a jeep he was riding in. Further, he states that he had a foreign object removed from his right eye in service and that this caused the onset of visual difficulties in this eye. He has also requested that an increased evaluation be assigned to his duodenal ulcer with spastic colon, right inguinal area scar, and his right peroneal neuritis. In regard to his ulcer and spastic colon, the veteran has asserted that he experiences constant pain, bloating, diarrhea and nausea. He states that his peroneal neuritis is more disabling than the current evaluation would suggest. He says that this injury has caused constant pain, numbness and right foot drop. He stated that his inguinal scar was sensitive and often aches. The veteran has also requested that he be granted service connection for right foot drop, a right wrist disability and a low back disability as a direct result of his service-connected right peroneal neuritis. He states that the peroneal nerve damage has now resulted in the onset of right foot drop. He alleges that he has experienced several falls because of his difficulties with his right lower extremity. These falls have resulted in right wrist and low back injuries and their resultant residuals, to include pain and limitation of motion. He further alleges that he has submitted new and material evidence that supports his contentions that he suffered a back injury in service that has resulted in the development of a chronic back disability. He also states that there is sufficient new and material evidence to support a finding that he suffers from PTSD as a result of his Vietnam service. Because of his various disabilities, the veteran contends that he is unable to maintain substantially gainful employment. In fact, he notes that he has been unable to work since 1988. Several other issues have also been raised by the veteran. He alleges that the RO committed clear and unmistakable error when it denied service connection for PTSD and a low back disability. He has requested that he be granted financial assistance in obtaining special adaptive equipment for his automobile. He asserts that his right lower extremity disabilities have rendered this extremity useless and has made the use of hand controls a must. He has requested that an earlier effective date be assigned to the grant of service connection for residuals of the right knee injury. Finally, he has alleged that a separate disability evaluation should be assigned to his service connected spastic colon. DECISION OF THE BOARD The Board, in accordance with the provisions of 38 U.S.C.A. § 7104 (West 1991), has reviewed and considered all of the evidence and material of record in the veteran's claims files. Based on its review of the relevant evidence in this matter, and for the following reasons and bases, it is the decision of the Board that the evidence supports an increased evaluation for right peroneal neuritis, duodenal ulcer with spastic colon, and a separate compensable evaluation for the residuals of right knee injury, supports a finding that new and material evidence has been submitted to reopen a claim for service connection for PTSD, as well as a grant of service connection for PTSD, and supports a grant of a total disability evaluation due to individual unemployability. The preponderance of the evidence is against service connection for right wrist, skin, right elbow, claimed right foot drop, right eye, and low back disabilities, against an increased evaluation for a right inguinal area scar, against a finding that new and material evidence has been submitted to reopen a claim for direct service connection for a low back disability, against finding clear and unmistakable error in the prior denials of service connection for PTSD and a low back disability, and against financial assistance for adaptive equipment. It is also the decision of the Board that the veteran has failed to allege error of either fact or law in the decision of the RO which allowed an earlier effective date to June 20, 1969, for the grant of service connection for residuals of a right knee injury, and that a separate rating for a spastic colon may not be assigned. FINDINGS OF FACT 1. The veteran's duodenal ulcer with spastic colon is manifested by abdominal pain, very frequent periods of diarrhea and essentially constant abdominal distress; impairment of health, periodic vomiting or recurrent hematemesis or melena are not shown. 2. The veteran's right inguinal area scar is manifested by subjective complaints of sensitivity, with no objective findings. 3. The RO denied entitlement to service connection for a low back disability in November 1981. 4. Additional evidence submitted since that time fails to show that the veteran's current back disability, to include arthritis, was related to an event in service, or that arthritis manifested to a compensable degree within one year of separation. 5. The RO denied entitlement to service connection for PTSD in October 1983. 6. Additional evidence submitted since that time reveals that the veteran suffers from PTSD as a result of his service. 7. There is no causal relationship between the veteran's service connected right lower extremity disabilities and the injury that led to the right wrist disability. 8. The veteran's service connected disabilities do prevent him from working at a substantially gainful occupation. 9. The veteran's skin rash noted in service was acute and transitory in nature, resolving by discharge, and it is not shown to be related to any disorder noted after discharge; the veteran's current skin disorder is not shown to be related to herbicide (or Agent Orange) exposure. 10. Under the schedule for rating disabilities, a rating for ulcer disease cannot be combined with a rating for a spastic colon. 11. The veteran's right elbow disability was not present during service. 12. The veteran does not suffer from foot drop that is demonstrated by a loss of active movement of the muscles with a dangling right foot or that is a separate and distinct manifestation or disability from the right foot impairment that is due to the right peroneal injury already service connected. 13. The veteran's inservice right eye complaints, which consisted of the removal of a foreign object, were acute and transitory in nature and resolved without residuals. 14. The veteran's right peroneal neuritis is manifested by severe incomplete paralysis of the common peroneal nerve. 15. The veteran's residuals of injury to the right knee are currently manifested by limitation of motion, posterior lateral pain and x-ray evidence of a chip fracture. 16. The veteran was granted an earlier effective date for his service-connected right knee injury residuals to June 20, 1969, the day following separation from service. 17. The veteran has actual remaining function in the right foot such that balance and propulsion would not be equally well accomplished by an amputation stump below the knee with suitable prosthetic appliance; therefore, the veteran does not have loss of use of the right foot as the result of service connected disability. 18. The RO denied entitlement to service connection for PTSD in October 1983; this decision was consistent with the evidence in the file at that time and constituted a reasonable exercise of rating judgment. 19. The RO denied entitlement to service connection for a low back disability in November 1981; this decision was consistent with the evidence in the file at that time and constituted a reasonable exercise of rating judgment. 20. There is no causal relationship between the veteran's service-connected right lower extremity disabilities and the injuries that led to the development of a low back disability. CONCLUSIONS OF LAW 1. The criteria for a 30 percent disability evaluation for duodenal ulcer with spastic colon have been met. 38 U.S.C.A. §§ 1155, 5107(a) (West 1991); 38 C.F.R. §§ 3.321, 4.7, 4.110, 4.112, 4.113, 4.114 and Diagnostic Codes 7305, 7319 (1994). 2.

Evidence received since the RO denied entitlement to service connection for a low back disability in 1981 is not new and material, and the November 1981 decision of the RO is thus final and the claim is not reopened. 38 U.S.C.A. §§ 1101, 1110, 1112, 1113, 5107(a), 5108, 7105 (West 1991); 38 C.F.R. §§ 3.104(a), 3.156(a), 3.303(c), 3.307, 3.309, 20.302 (1994). 4. Evidence received since the RO denied entitlement to service connection for PTSD in 1983 is new and material, and the claim is reopened. 38 U.S.C.A. §§ 5107(a), 5108, 7105 (West 1991); 38 C.F.R. §§ 3.104(a), 3.156(a), 20.302 (1994). 5. PTSD was incurred in wartime service. 38 U.S.C.A. §§ 1110, 5107(a) (West 1991); 38 C.F.R. § 3.304(f) (1994). 6. The veteran's right wrist disability is not proximately due to or the result of his service connected right lower extremity disabilities. 38 U.S.C.A. § 5107(a) (West 1991); 38 C.F.R. § 3.310(a) (1994). 7. The veteran is unemployable due to service connected disabilities. 38 U.S.C.A. §§ 1155, 5107(a) (West 1991); 38 C.F.R. §§ 3.340, 3.341, 4.16 (1994). 8. A chronic skin disorder was not incurred in or aggravated by service, nor may it be presumed to have been so incurred. 38 U.S.C.A. §§ 1110, 1113, 1116, 5107(a) (West 1991); 38 C.F.R. §§ 3.303(b), 3.307(a)(6), 3.309(e) (1994). 9. A separate disability rating for the service-connected spastic colon may not be assigned. 38 C.F.R. §§ 4.14, 4.114 (1994). 10. A right elbow disability, to include retained foreign bodies, was not incurred in or aggravated by active duty. 38 U.S.C.A. § 1110, 5107(a) (West 1991). 11. The veteran is service-connected for the right foot impairment due to residuals of a right peroneal nerve injury; he does not have a right foot drop that may be separately service connected and rated. 38 U.S.C.A. §§ 1110, 1153 (West 1991); 38 C.F.R. §§ 3.310(a), 4.14, 4.55(g) (1994). 12. The veteran does not a chronic right eye disability which was incurred in or aggravated by service. 38 U.S.C.A. §§ 1110, 5107(a) (West 1991); 38 C.F.R. § 3.303(b) (1994). 13. The criteria for a 30 percent evaluation for right peroneal neuritis have been met. 38 U.S.C.A. §§ 1155, 5107(a) (West 1991); 38 C.F.R. §§ 3.321, 4.1, 4.2, 4.7, 4.10, and Diagnostic Code 8621 (1994). 14. A separate 10 percent rating for the service-connected residuals of injury to the right knee is warranted. 38 U.S.C.A. §§ 1155, 5107(a) (West 1991); 38 C.F.R. §§ 4.1, 4.2, 4.10, 4.40 and Code 5257 (1994). 15. The veteran has alleged no error of fact or law in the determination of the earlier effective date of June 20, 1969, for the grant of service connection for right knee injury residuals. 38 U.S.C.A. §§ 5107(a), 7105(d)(5) (West 1991). 16. The eligibility criteria for financial assistance in acquiring an automobile or other conveyance or special adaptive equipment have not been met. 38 U.S.C.A. §§ 3901, 3902, 5107(a) (West 1991); 38 C.F.R. §§ 3.808, 4.63 (1994). 17. The decision to deny service connection for PTSD in October 1983 was not clearly and unmistakably erroneous. 38 U.S.C.A. §§ 5107(a), 7105 (West 1991); 38 C.F.R. § 3.105(a) (1994). 18. The decision to deny service connection for a low back disability in November 1981 was not clearly and unmistakably erroneous. 38 U.S.C.A. §§ 5107(a), 7105 (West 1991); 38 C.F.R. § 3.105(a) (1994). 19. The veteran's low back disability is not proximately due to or the result of his service connected right lower extremity disabilities. 38 U.S.C.A. § 5107(a) (West 1991); 38 C.F.R. § 3.310(a) (1994). REASONS AND BASES FOR FINDINGS AND CONCLUSIONS The veteran's claims, with the exception of the claim for an earlier date for service connection of right knee injury residuals, are well grounded within the meaning of 38 U.S.C.A. § 5107(a). That is, we find that he has presented claims which are plausible. We are also satisfied that all relevant facts have been properly developed. The record is devoid of any indication that there are other records available which should be obtained. Therefore, no further development is required in order to comply with the duty to assist mandated by 38 U.S.C.A. § 5107(a). I. Service connection claims Under the applicable criteria, service connection may be granted for a disability the result of disease or injury incurred in or aggravated by service. 38 U.S.C.A. § 1110 (West 1991). For the showing of a chronic disease in service there is required a combination of manifestations sufficient to identify the disease entity, and sufficient observation to establish chronicity at the time, as distinguished from merely isolated findings or diagnosis including the word "chronic." Continuity of symptomatology is required where the condition noted during service is not, in fact, shown to be chronic or where the diagnosis of chronicity may be legitimately questioned. When the fact of chronicity in service is not adequately supported, then a showing of continuity after discharge is required to support the claim. 38 C.F.R. 3.303(b) (1994). A. Entitlement to service connection for a skin disorder claimed as a residual of exposure to herbicides in Vietnam (or Agent Orange). According to 38 C.F.R. § 3.307(a)(6) (1994), the term herbicide agent means a chemical in an herbicide used in support of the United States and allied military operations in the Republic of Vietnam during the Vietnam era. The diseases listed at 38 C.F.R. § 3.309(e) (1994) shall be service connected if they manifest to a degree of 10 percent or more at any time after service, except that chloracne or other acneform disease consistent with chloracne and porphyria cutanea tarda shall have become manifest to a degree of 10 percent or more within one year after the last date on which the veteran was exposed to an herbicide agent during active military, naval, or air service. If a veteran was exposed to an herbicide agent during active military, naval, or air service, the following diseases shall be service connected if the requirements of 38 C.F.R. § 3.307(a)(6) are met even though there is no record of such disease: chloracne or other acneform disease consistent with chloracne; Hodgkin's disease; multiple myeloma; Non-Hodgkin's lymphoma; porphyria cutanea tarda; respiratory cancers (cancer of the lung, bronchus, larynx or trachea); soft-tissue sarcoma (other than osteosarcoma, chondrosarcoma, Kaposi's sarcoma, or mesothelioma). The term soft-tissue sarcoma includes the following: adult fibrosarcoma; dermatofibrosarcoma protuberans; malignant fibrous histiocytoma; liposarcoma; leiomyosarcoma; epithelioid leiomyosarcoma (malignant leiomyoblastoma); rhabdomyosarcoma; ectomesenchymoma; angiosarcoma (hemangiosarcoma and lymphangiosarcoma); proliferating (systemic) angioendotheliomatosis; malignant glomus tumor; malignant hemangiopericytoma; synovial sarcoma (malignant synovioma); malignant giant cell tumor of the tendon sheath; malignant schwannoma, including malignant schwannoma with rhabdomyoblastic differentiation (malignant Triton tumor), glandular and epithelioid malignant schwannomas; malignant mesenchymoma; malignant granular cell tumor; alveolar soft part sarcoma; epithelioid sarcoma; clear cell sarcoma of the tendons and aponeuroses; extraskeletal Ewing's sarcoma; congenital and infantile fibrosarcoma; and malignant ganglioneuroma. 38 C.F.R. § 3.309(e) (1994). The new regulations pertaining to Agent Orange exposure, expanded to include all herbicides used in Vietnam, now provide for a presumption of exposure to herbicide agents for veterans who served on active duty in Vietnam during the Vietnam era. 38 C.F.R. § 3.307(a)(6) (1994). The veteran's active duty included service in Vietnam during the Vietnam era from May 30, 1967, to May 21, 1968. Consequently, it is presumed that he was exposed to Agent Orange or other herbicide agents while in Vietnam. The veteran's service medical records reveal that in June 1967 he presented with complaints that he felt slightly nauseated. He had also developed an elevated rash. The physical examination conducted at that time was within normal limits. The diagnosis was undiagnosed disease manifested by a skin rash. His last day of service in Vietnam was on May 21, 1968. The remainder of the service medical records make no reference to a skin disorder. Following his discharge from the military, the veteran was examined by VA in October 1969. Except for some mild pustular acne over the face and upper chest, the examination of his skin was normal. A July 1976 VA examination found that his skin was normal. A November 1982 outpatient treatment record from the VA Dermatology clinic noted that he had numerous mild skin complaints. These included recurrent folliculitis on the groin and buttocks, recurrent lesions on the penis, probable herpes and cysts behinds the left ear that occasionally become infected. No disease associated with exposure to Agent Orange was diagnosed. During his January 1991 personal hearing, the veteran indicated that he was receiving money from the Agent Orange Fund. VA outpatient treatment records developed between January 1990 and March 1992 reflect treatment for a erythematous macular rash, a nodular lesion and seborrheic keratoses of the face in February 1991. In April 1991, objective examination revealed a 3 mm light brown scaly papule on the left forearm, two red papules on the face and two brown papules that dimpled when pinched on the left shoulder. The assessment was questionable seborrheic keratoses on the left forearm and rosacea. In July 1991, rosacea, seborrheic keratosis, questionable dyshidrotic eczema and xerosis were diagnosed. In September 1992, the veteran testified at a personal hearing, during which he indicated that he suffers from chloracne as a result of his exposure to Agent Orange in service. He stated that this condition first began in service and was noted as a rash. He said that he currently is being treated with topical ointments. He admitted that the diagnosis now is rosacea, and contended that the symptoms that he now has are basically the same as those he had in service. In January 1994, the veteran was examined by the VA. It was noted that he was exposed to Agent Orange during service, and that he did have one complaint of a rash in service. Since that time, the veteran has complained of acne, multiple cysts, redness of the neck, and dry and cracking skin of the tips of the fingers. The objective examination found that there were telangiectasia's and hyperpigmentation of the face and neck. He also had numerous telangiectasia's of the upper chest. There were about ten small acneform lesions on the chest and back. There was also dry hyperkeratosis of the tips of the fingers without vesicles. A dermal papule with a "dimple sign" was present on the right posterior thigh. All clinical tests were negative. The diagnoses were poikiloderma of Civatte of the face and neck; telangiectasia's of the chest; acne vulgaris of the chest and back; hand dermatitis; and dermatofibroma of the right posterior thigh. The veteran testified at a personal hearing in September 1994. He stated that he applies topical medication to treat what he called chloracne. He noted that in 1983 a punch biopsy had diagnosed erythemas, which is redness caused either by chemical poisoning or sunburn. He commented that the January 1994 VA examination had diagnosed acneiform lesions that were caused by exposure to Agent Orange. He admitted during this testimony that no doctor had ever told him that his skin condition was related to Agent Orange exposure, nor that chloracne had ever been diagnosed, although he asserted that his symptoms were consistent with this disability. The veteran's wife submitted a statement in September 1994 which noted that, prior to his service, the veteran's skin was clear. However, after his return form Vietnam, his skin, particularly his neck, was very red. He also had cysts removed and suffered from blisters on his fingers. After carefully reviewing the evidence of record, it is the opinion of the undersigned that entitlement to service connection for a skin disorder the result of exposure to Agent Orange is not warranted. Initially, it is noted that the veteran is presumed to have been exposed to Agent Orange during his tenure in Vietnam. However, such exposure is not enough to establish entitlement to service connection for a skin disability. The veteran has been diagnosed with many different skin disorders, to include rosacea, hyperkeratosis, telangiectasia's, acne vulgaris, dermatitis, and eczema. The mild pustular acne noted in October 1969 was more than 2 years after the presentation of the acute and transitory rash in June 1967, and more than 1 year after he left Vietnam in May 1968. There is no medical evidence that the mild pustular acne represented chloracne or an acneform disease consistent with chloracne, and in any event there is no medical evidence that such a skin disorder became manifest to a 10 percent degree within one year after he left Vietnam. The veteran has never been diagnosed with any of the diseases enumerated in 38 C.F.R. § 3.309(e) (1993), which are the only diseases for which a presumption of service connection is warranted. The United States Court of Appeals for the Federal Circuit recently determined that the Veterans' Dioxin and Radiation Exposure Compensation Standards (Radiation Compensation) Act, Pub.L. No. 98-542, § 5, 98 Stat. 2715, 2727-29 (1984) does not preclude a veteran from establishing service connection with proof of actual direct causation. Combee v. Brown, 34 F. 3d 1039 (Fed. Cir. 1994). However, the United States Court of Veterans Appeals (Court) has held that where the issue involves medical causation, competent medical evidence which indicates that the claim is plausible or possible is required to set forth a well- grounded claim. Grottveit v. Brown, 5 Vet.App. 91, 93 (1993). The veteran's assertions of medical causation alone are not probative because lay persons (i.e. persons without medical expertise) are not competent to offer medical opinions. Moray v. Brown, 5 Vet.App. 211 (1993); Grottveit v. Brown, 5 Vet.App. 91 (1993); Espiritu v. Derwinski, 2 Vet.App. 492 (1992). Again, the veteran did experience an acute skin rash shortly after he arrived in Vietnam in June 1967. However, no further treatment for a skin problem was noted in the service medical records. Clearly, this condition resolved by discharge. No further mention of a chronic skin problem was made until 1982, several years after separation. Therefore it cannot be argued that continuity of symptomatology has been established, thus demonstrating that no chronic skin disorder began in service. It is therefore concluded that the preponderance of the evidence is against a finding of entitlement to service connection for a chronic skin disability as the result of exposure to Agent Orange; and against a finding that any of his current skin disorders are related to his period of service. B. Service connection for retained foreign bodies in the right elbow. The veteran has alleged that he received shrapnel fragment wounds to the right elbow in service, and that service connection should be granted for the retained fragments. A review of the service medical records reveals no clinical records pertaining to an injury of the right elbow. His May 1969 separation examination noted his comment that he had been treated for his right elbow. However, the nature of the disorder and the type of treatment received was not indicated. The objective examination of the upper extremities was completely negative. Two VA examinations, conducted in October 1969 and July 1976, are also negative for any complaints involving this elbow. The objective examinations were also silent as to any disability of this joint. A January 1991 VA outpatient treatment record referred to the removal of shrapnel from the veteran's right elbow. The veteran testified at a personal hearing in January 1992 during which he stated that he had been injured when a jeep he was riding in was either hit with mortar fire or ran over a land mine. In either case, he said that he received shrapnel fragments in the right elbow. He claimed that a recently performed MRI found metallic fragments in the elbow. A second personal hearing was held in September 1992 at which time he stated that he felt that a March 1990 fall had possibly shifted the metallic fragments in his elbow so that they were now affecting the nerves. A January 1994 VA neurological examination showed that there was mild generalized weakness in the right upper extremity. In February 1994, the veteran was examined by VA. He gave a history of receiving a shrapnel fragment wound to the right elbow in 1967 or 1968 after an explosion. The objective examination revealed that range of motion was 0 to 120 degrees with pain upon extreme flexion. He displayed 80 degrees of pronation and supination without pain. There was tenderness to palpation over the lateral aspect of the arm, as well as over the lateral epicondyle with even light touch. The right upper extremity displayed 5/5 motor strength. A July 1991 x-ray study was reviewed and was noted to reveal no evidence of shrapnel or foreign bodies in the right elbow. The diagnosis was chronic pain in the right elbow of unclear etiology. In April 1994, a private physician noted that the veteran complained of neck and right arm pain which appeared to be secondary to a herniated disc at C6-7. There were degenerative changes at this level as well. These changes were compromising the nerve root and causing his right upper extremity symptoms. In September 1994, the veteran testified at a personal hearing. He stated that the problems with his right elbow did not manifest itself until after his March 1990 fall. He said that he was unaware of the metal fragments in his elbow. However, after his 1990 fall, an MRI was performed. He asserted that this study had something to do with shifting the metal fragments. As a consequence, these fragments were now pressing against the interosseous and ulnar nerves. He commented that he received this shrapnel fragment wound during the Tet offensive, and that it was noted on his 1969 separation examination. After carefully reviewing the evidence of record, it is the conclusion of the undersigned that entitlement to service connection for retained foreign bodies in the right elbow is not warranted. It is noted that the veteran's separation examination contains one mention, by the veteran, that he had been treated for a right elbow injury. However, such a claim could not be verified by a review of the objective clinical records. These records make no reference to treatment for any type of right elbow injury, let alone a shrapnel fragment wound. While the veteran continues to assert throughout his testimony that he received shrapnel fragment wounds, it is noted these claims cannot be confirmed with the objective evidence. The post service records included two VA examinations, one conducted in October 1969, the other in July 1976. Neither of the examinations made any reference to a right elbow disability. In fact, artifacts were not noted in the record until a June 1991 MRI of the right forearm. This test was performed after the veteran had injured his right upper extremity in a fall in March 1990. The report of this study began with a history of a right elbow fracture. The MRI was requested to rule out reflex sympathetic dystrophy following a right wrist fracture in March 1990. Noted were metallic artifacts in the proximal right forearm, possibly related to reported fracture of the right elbow. No mention was made of shrapnel fragments or wounds. Further, as noted above, a July 1991 X-ray study revealed no evidence of shrapnel in the right elbow. Significantly, no external scarring was ever referred to, despite the expectation that such scarring would have resulted from shell fragments. Moreover, the veteran contended during his September 1994 hearing that, prior to his 1990 fall, he had been unaware of any foreign bodies in his right elbow, an assertion that is not credible, considering the traumatic nature of any shrapnel fragment wound. It is unlikely that he would have been unaware of these fragments had they been obtained as he alleges. Therefore, while questionable evidence of artifacts in the right forearm was noted after his March 1990 injury, there is absolutely no objective evidence of record to relate these to his period of active duty. Rather, they appear to be related to an injury sustained after service. Therefore, the preponderance of the evidence is against a finding of entitlement to service connection for retained foreign bodies in the right elbow, as the result of shrapnel fragment wounds. C. Entitlement to service connection for the residuals of trauma to the right eye. A review of the service medical records reveals that, in November 1968, a small woody foreign body was removed from the veteran's right eye. Visual acuity in this eye was noted to be 20/30. It was also mentioned that he did wear glasses. The separation examination performed in May 1969 made no reference to an eye disability. In October 1969, the veteran was examined by VA. His eyes were noted to be normal, with visual acuity of 20/30. A July 1976 VA examination found that his pupils were round and regular. They responded equally and were reactive to light. The movements of the eye were normal. Visual acuity was 20/20. A January to February 1983 VA eye examination was also normal. None of the examinations referred to any residuals caused by the removal of a woody fragment from his right eye. An October 1990 VA record noted that the veteran's bilateral visual acuity was 20/25. VA outpatient treatment records developed between January 1990 and March 1992 noted his complaints in January 1991 of problems with visual acuity in the right eye. He gave a history of a shrapnel wound to this eye. It was noted that he needed glasses in order to drive. The assessment was rule out Hollenhurst plaques. In July 1991 he continued to complain of decreased visual acuity in the right eye. He gave a history of a shrapnel wound to this eye. In September 1992 the veteran testified at a personal hearing. He said that he was seen in service in 1968 for a problem with his right eye. He stated that the record does not refer to a diagnosis but that he believed that his retina was referred to. He said that he was issued glasses while in the service. He stated that he currently suffers from recurrent infections and swelling in this eye as a result of the inservice injury. A September 1993 VA examination noted his bilateral decreased visual acuity. A January 1994 neurological examination found full visual fields, with pupils that were normal in appearance, and were reactive to light and accommodation. There was full extraocular movement without nystagmus. The veteran then testified at an additional personal hearing in September 1994. He stated that he had a foreign body removed from his right eye while in service. He noted that VA had diagnosed conjunctivitis, corneal abrasions and Hollenhorst plaques, which he said were developmental abnormalities. He rendered his opinion that the removal of the foreign body in service had caused scarring that was affecting his vision. After a careful review of the evidence of record, it is the opinion of the undersigned that a finding of entitlement to service connection for the residuals of trauma to the right eye is not warranted. Initially, it is noted that a small woody foreign body was removed from the veteran's right eye in November 1968, after he left Vietnam. However, no other treatment was recorded. The separation examination of May 1969 made no reference to any complaints referable to this eye, nor were any residuals identified. The VA examination conducted in October 1969, shortly after his discharge, also noted no trauma residuals of the right eye. What was noted was visual acuity of 20/30, the same visual acuity that was noted in November 1968 when the foreign body was removed. Clearly, the minor trauma to the right eye, manifested by a small woody fragment in the eye, was acute and transitory in nature, resolving without residuals. This finding is confirmed by the treatment records developed after separation which show some slight decrease in visual acuity, which has never been related to trauma. While the veteran's opinion that the removal of the foreign body caused scarring that has effected his vision has been noted, the veteran is a lay person who is not qualified to render an opinion as to medical causation. Espiritu v. Derwinski, 2 Vet.App. 492 (1992). The objective medical evidence of record contains no such opinion. No record has ever mentioned that the veteran suffers from traumatic loss of vision in the right eye. Therefore, the preponderance of evidence is against finding entitlement to service connection for the residuals of trauma to the right eye. II. Increased and separate evaluation claims Under the applicable criteria, disability evaluations are determined by the application of a schedule of ratings which is based on the average impairment of earning capacity. Separate diagnostic codes identify the various disabilities. 38 U.S.C.A. § 1155 (West 1991); 38 C.F.R. Part 4 (1994). When a question arises as to which of two evaluations shall be assigned, the higher evaluation will be assigned if the disability picture more nearly approximates the criteria required for that rating. Otherwise, the lower rating will be assigned. 38 C.F.R. § 4.7 (1994). VA has a duty to acknowledge and consider all regulations which are potentially applicable based upon the assertions and issues raised in the record and to explain the reasons used to support the conclusion. Schafrath v. Derwinski, 1 Vet.App. 589 (1991). These regulations include, but are not limited to, 38 C.F.R. § 4.1, that requires that each disability be viewed in relation to its history and that there be an emphasis placed upon the limitation of activity imposed by the disabling condition, and 38 C.F.R. § 4.2 which requires that medical reports be interpreted in light of the whole recorded history, and that each disability must be considered from the point of view of the veteran's working or seeking work. 38 C.F.R. § 4.10 states that, in cases of functional impairment, evaluations are to based upon lack of usefulness, and medical examiners must furnish, in addition to etiological, anatomical, pathological, laboratory and prognostic data required for ordinary medical classification, full description of the effects of the disability upon a person's ordinary activity. This evaluation includes functional disability due to pain under he provisions of 38 C.F.R. § 4.40. These requirements for the consideration of the complete medical history of the claimant's condition operate to protect claimants against adverse decisions based upon a single, incomplete or inaccurate report and to enable VA to make a more precise evaluation of the level of disability and any changes in the condition. A. Entitlement to an increased evaluation for right peroneal neuritis. Under Diagnostic Code 8521, a 10 percent evaluation is warranted for mild incomplete paralysis of the common peroneal nerve. A 20 percent evaluation requires moderate incomplete paralysis and 30 percent evaluation requires severe incomplete paralysis. A 40 percent evaluation requires complete paralysis, evidenced by foot drop and slight droop of the first phalanges of all toes. There is an inability to dorsiflex the foot, extension (dorsal flexion) of the proximal phalanges of the toes and abduction of the foot are lost; adduction is weakened; and anesthesia covers the entire dorsum of the foot and toes. The evidence of record indicates that the veteran injured his right lower extremity as the result of a car accident in 1969. Throughout the 1970's the veteran complained of right knee pain and instability, as well as numbness in the right leg. A January 1981 EMG revealed evidence of involvement of the peroneal nerve at the site of the traumatic right knee injury. An April 1981 private medical record included his complaint that his right lower extremity numbness was worsening. A neurological examination revealed that there was sensory hypalgesia over the peroneal distribution. The impression was possibility of right peroneal neuropathy. A December 1981 EMG confirmed the involvement of the right peroneal nerve. A VA treatment record from April 1982 revealed that the diagnosis was right peroneal nerve entrapment neuropathy. He underwent a right peroneal nerve exploration, decompression and neurolysis. The post surgical diagnosis was the same. A private record from June 1982 contained the same complaints of right lower extremity numbness. It was noted that the most recent EMG had noted no changes in the status of the right peroneal nerve. The assessment was status post peroneal nerve decompression and peroneal nerve neuropathy on the right side. Sympathetic blocks were performed in January 1983. While this made the foot feel warmer, it did not improve the pain. A January to February 1983 VA examination contained the veteran's history that he had injured his right knee in 1969. He experienced swelling in the knee, which eventually subsided; however, right lower extremity numbness ensued. During this examination, he complained that he still had numbness at and below the knee level; he also stated that his right leg occasionally felt unstable. The physical examination revealed that the circumference of the right calf was about a quarter of an inch smaller than the left. There was an S shaped, six inch scar along the lateral side of the right knee, which was numb to pinprick. The lower aspect of the right foot, particularly the second and third toes, were quite cold. The pedal pulses were palpable. His toes were numb upon testing. Flexion of the third and fourth toes seemed somewhat less complete than the left. The right knee flexed to 80 degrees, and extended to 180 degrees. Patellar and ankle reflexes were present. The diagnoses were residuals of an injury to the right knee and right peroneal neuritis. A June 1983 VA outpatient treatment record included the veteran's complaints of right leg numbness, pain, and weakness. He stated that he experienced pain that radiated from the lateral aspect of the right hip, which occasionally radiated into the anterior thigh down the leg to the lateral aspect of the foot and ankle. His right knee was noted to be normal at that time. The diagnosis was peripheral neuropathy with post laminectomy syndrome. The veteran testified at two personal hearings in 1992, in January and September. During the January hearing he stated that he had injured his right knee in an explosion. During the September hearing he said that between 1969 and 1990 he had experienced repeated right leg give way. He said that he had no control over this extremity and was now forced to wear a brace. He felt that his right leg give way was related to his right leg injury. The veteran submitted an April 1993 statement from his private physician which stated that the veteran had suffered from right lateral thigh and calf numbness ever since his 1969 accident in service. Since the initial injury, he had experienced episodes of pain and right knee swelling. His complaints continued and a neurolysis was eventually performed. However, his pain continued. It was noted that he had an abnormal gait due to the right leg injury. The assessment was right leg dysfunction caused by the right leg injury. A July 1993 VA x-ray revealed degenerative changes involving the posterior horn of the right medial meniscus without a tear. The lateral meniscus appeared normal. The ligaments were unremarkable. A September 1993 VA examination noted the veteran's chief complaints of severe right lower extremity instability and a limp. The right lower extremity showed a decrease in patellar and Achilles tendon reflexes. An examination of the right knee revealed that there was no swelling of the joint. Range of motion was 0 to 120 degrees. Right foot plantar flexion was to 30 degrees with dorsiflexion of 0 degrees. It was noted that the veteran had right peroneal nerve disease with decompression and subsequent complete foot drop for which he wears a prosthesis. The diagnoses were right external peroneal nerve syndrome with surgical intervention; right leg peroneal nerve inflammation and decompression of the peroneal nerve. A private physician noted in September 1993 noted that the veteran had been wearing a brace since the 1969 right lower extremity injury to compensate for right leg weakness and "turning in " of the ankle. He underwent a right peroneal decompression without significant improvement. He was wearing a lateral wedge to prevent inversion of the ankle. The physical examination revealed that he ambulated with a conventional cane held in the left hand. No distinct gait deviations were appreciated. The evaluation of the lower extremities revealed normal musculature and normal range of motion. No frank atrophy or weakness was detected. An EMG noted that all muscles of the right lower extremity were normal. The assessment was right leg and knee pain. A January 1994 neurological examination noted right peroneal nerve dysfunction. An EMG revealed that the right superficial peroneal sensory demonstrated normal latency with borderline decreased amplitude. Plantar flexion was 5+ and dorsiflexion was 4+. Dorsiflexion of the foot in eversion and inversion was 4+ as well. The ankle reflex was absent on the right. The diagnosis stated that the veteran had some mild weakness of the right foot upon dorsiflexion, eversion and inversion. This would correlate with his complaints that his foot tends to turn in when he removes the foot brace. The diagnosis did not indicate the presence of foot drop. The February 1994 VA examination of the right knee revealed no effusion or swelling. Posterior lateral pain was noted. There was a large hypertrophic scar on the posterior lateral aspect of the right knee extending into the posterior proximal calf. This was tender to palpation, though there was no palpable swelling or masses. There was a negative Tinel's sign over this scar. Range of motion was from 5 to 110 degrees. The knee displayed no crepitus or varus and valgus instability. A July 1991 x-ray was reviewed, which was essentially unremarkable except for the possibility of a small chip fracture in the intercondylar notch. The diagnosis was chronic peroneal nerve injury of the right lower extremity. In April 1994, the veteran's private physician noted that the veteran's right leg was still unstable and required the use of an AFO brace to stabilize the ankle. After carefully reviewing the evidence of record, it is the opinion of the undersigned that a 30 percent disability evaluation under Diagnostic Code 8621 for the veteran's right peroneal nerve injury is justified. The record reveals that the veteran suffers from incomplete paralysis of the nerve that is severe in nature. This is demonstrated by the fact that his right foot "turns in" or inverts upon ambulation. Furthermore, this inversion of the foot has made it incumbent upon the veteran to wear a brace in order to stabilize the ankle enough so that he can walk without falling. Signifi-cantly, the September 1993 VA examination had also shown that plantar flexion was limited to 30 degrees, with dorsiflexion to 0 degrees. He also experiences persistent numbness in the right leg, with weakness and pain. This evidence indicates that the residuals of this right peroneal injury are severe in degree. However, a 40 percent disability under this code is not justified. Significantly, it is noted that the veteran does not suffer from complete paralysis of the right foot. He does not have foot drop, as noted by the January 1994 VA examination, nor does he exhibit slight droop of the first phalanges of all toes. What he does have is a difficulty with lateral motion of the foot. Further, the evidence does not indicate that extension of the proximal phalanges of the toes and abduction of the foot are lost. Finally, he does not, based on the evidence, experience anesthesia covering the entire dorsum of the foot and toes. Hence, no more than a 30 percent disability evaluation is warranted. B. A separate compensable rating for residuals of injury to the right knee joint. Generally, the evaluation of the same disability under various diagnoses is to be avoided. Disability from injuries to the muscles, nerves, and joints of an extremity may overlap to a great extent, so that special rules are included in the appropriate bodily system for their evaluation. Dyspnea, tachycardia, nervousness, fatigability, etc., may result from many causes; some may be service connected, others, not. Both the use of manifestations not resulting from service connected disease or injury in establishing the service connected evaluation and the evaluation of the same manifestation under different diagnoses are to be avoided. 38 C.F.R. § 4.14 (1994). However, the United States Court of Veterans Appeals (Court) has held that a disability can be assigned a separate disability evaluations under different diagnostic codes, providing that the symptomatology so rated is not duplicative or overlapping. Esteban v. Brown, 6 Vet.App. 259 (1994). Therefore, the veteran's right lower extremity peroneal nerve disability will be rated under Diagnostic Code 8621, which is based on Code 8521, paralysis of the peroneal nerve. The right knee joint disability will be rated under Code 5257, which refers to impairment of the knee. Such a separate evaluation is permissible given that the symptomatology addressed by these two disability codes is not duplicative, and is warranted by the facts in this case. 38 C.F.R. § 4.25(b) (1994). Slight impairment of either knee, including recurrent subluxation or lateral instability, will be rated 10 percent disabling. For a 20 percent rating, a moderate impairment of the knee is required. It is the opinion of the undersigned that a separate compensable evaluation for the residuals of the injury to the right knee is warranted. The most recent evidence of record demonstrates that motion of the knee is limited from 5 degrees of extension to 110 degrees of flexion. There is also some evidence of pain in the joint, as is demonstrated by his complaints of posterior lateral pain. The record evidences slight degree of impairment of the right knee, even though the complaints of instability are not now confirmed on clinical examination. The chip fracture is evidence of the old trauma, but any resulting impairment from this fracture is not shown. However, no more than a 10 percent disability evaluation is justified. The evidence does not indicate that the impairment of the knee is moderate in nature, particularly in light of the amount of range of motion. See, 38 C.F.R. § 4.71a, Diagnostic Codes 5260, 5261 (1994). Additionally, the evidence does not indicate that additional compensation is warranted on an extraschedular basis under 38 C.F.R. § 3.321. This disability has not resulted in frequent, repeated, periods of hospitalization, nor has it, standing alone, caused marked interference with employment. C. Entitlement to an increased evaluation for a duodenal ulcer with spastic colon. The veteran's gastrointestinal disease is rated under Diagnostic Codes 7305-7319. 38 C.F.R. §§ 4.27, 4.114 (1994). For many years, he has had ulcer disease, clinically identified in the duodenum and rated under Diagnostic Code 7305. 38 C.F.R. §§ 4.110, 4.114 (1994). In the lower gastrointestinal tract, his disability has been assessed as either an irritable bowel syndrome or a spastic colon syndrome; in either case the appropriate diagnostic code is 7319. 38 C.F.R. §§ 4.113, 4.114 (1994). While the current 20 percent disability evaluation is based on the ulcer disease, as set forth below we find that a rating under Diagnostic Code 7319 would be more appropriate. In the instant case, the veteran has in effect requested that an increased evaluation be assigned to his duodenal ulcer with spastic colon under either Diagnostic Code 7305 or 7319. Diagnostic Code 7305, which rates duodenal ulcers, provides that a 20 percent disability evaluation is warranted for a moderate condition, manifested by recurring episodes of severe symptoms two or three times a year averaging 10 days in duration, or with continuous moderate manifestations. A 40 percent evaluation requires a moderately severe condition. This is described as less than severe but with impairment of health manifested by anemia and weight loss, or by recurrent incapacitating episodes averaging 10 or more in duration at least four or more times a year. A 30 percent disability evaluation for irritable colon syndrome under Diagnostic Code 7319 requires that the condition be severe in nature, manifested by diarrhea, or alternating diarrhea and constipation, with more or less constant abdominal distress. A review of the service medical records reveals that the veteran was seen in July 1968 for complaints of stomach pain. At that time there was no change in bowel movements. The abdominal examination was essentially normal, save for tenderness in the lower quadrants and hyperactive bowel sounds. The impression was spastic colon syndrome. By the 25th of that month, he was complaining of abdominal pains that had lasted for five days. He noted that the pains were sharp in nature; he also reported an intolerance to certain foods and coffee. The abdomen was soft and non-tender. The impression was dyspepsia, rule out peptic ulcer disease. In November 1968, he presented with complaints of a slight, sharp umbilical pain, which was throbbing in nature. He noted that a bland diet had greatly helped in alleviating his symptoms. The objective examination found a mildly tender peri- umbilical area. As part of a VA examination performed in October 1969, an upper gastrointestinal (UGI) series was conducted. This revealed that the veteran's esophagus, stomach and duodenum appeared normal. The physical examination showed that his abdomen was soft and tender across the duodenum, mid-abdomen, and the left side of the umbilical area. No disease of the UGI tract was diagnosed. An October 1974 private hospital report revealed that the veteran was complaining of abdominal pain and diarrhea. There was no particular dyspepsia, nausea or vomiting. The physical examination revealed a moderate amount of tenderness in the left lateral abdominal quadrant. The impression was irritable bowel syndrome. In July 1976, the veteran was examined by VA. A UGI series showed that the duodenum was definitely deformed. There was slight tenderness on the left side of the abdomen. The diagnosis was active ulcer disease. Throughout the 1970's, the veteran continued to be treated for complaints of abdominal pain, and diarrhea. In 1976 he noted blood in the stool. A March 1979 VA examination referred to these complaints of recurrent abdominal distress with diarrhea. An UGI series was normal, except for a minimal deformity of the duodenal bulb. He displayed moderate tenderness in the epigastrium and right lower quadrant. The diagnosis was duodenal ulcer with spastic colon. A March to May 1980 VA examination report indicated that the veteran still suffered from bloody, loose stool, accompanied by nausea and a bloated feeling. Again, an UGI series revealed active ulcer disease in the duodenal bulb. Another examination performed by VA between January and February 1983 contained his continuing complaints of epigastric distress, heartburn, gaseousness, abdominal cramping and diarrhea with occasional bright red blood. He stated that his weight had slipped from 180 to 160 pounds. The objective examination showed that his abdomen was tender to palpation in both lower quadrants. The sigmoid colon felt spastic, and his epigastrium was sensitive. The diagnosis was peptic ulcer disease and spastic colon. These symptoms persisted into 1990. A VA outpatient treatment record from September 1990 noted his chief complaints as sharp, burning umbilical pain and nausea. He also complained of diarrhea with occasional bloody stool. The abdomen was soft with diffuse tenderness to palpation. There were no masses or organomegaly. In January 1991, he was hospitalized by VA, at which time dyspepsia, gastroesophageal reflux disease (GERD) and a history of peptic ulcer disease were diagnosed. Throughout 1991, his complaints of persistent, daily, occasionally bloody diarrhea continued and probable irritable bowel syndrome was diagnosed. In January 1992, the veteran testified at a personal hearing. He stated that his stomach condition had progressively worsened since 1990. He noted that he suffered from constant diarrhea, and experienced stomach cramps, heartburn, indigestion and gas. He noted that his diarrhea occurred 5 to 6 times each day. A March 1992 VA outpatient treatment record confirmed the diagnosis of irritable bowel syndrome. An August 1992 flexible sigmoidoscopy was normal. Probable GERD was diagnosed, as was diarrhea. In a September 1992 personal hearing, the veteran stated that his ulcer and his colitis had increased in severity. He noted that he was taking Zantac for his stomach trouble. He also said that he had to be cautious about what he eats. He suffered from heartburn, diarrhea, belching and abdominal cramps. A September 1993 VA examination noted that the veteran did not appear to be anemic or malnourished. He stated that his diarrhea was almost constant, occurring 4 to 5 times per day, with no intermittent constipation. This diarrhea was accompanied by intestinal rumbling, eructation and flatulence. The diagnosis was spastic colitis. Active peptic ulcer disease since 1968 was also noted. Again, he was not anemic and was without periodic vomiting. However, he did experience constant reflux. There was no current hematemesis or melena. He complained of pain in the epigastric area and left lower quadrant. The diagnosis was active peptic ulcer disease. In January 1994, the veteran underwent an extensive evaluation by VA. The UGI examination recorded his complaints of nausea and heartburn. The objective examination noted that he did not appear to be anemic. He denied vomiting and recurrent hematemesis or melena. He experienced pain in the substernal area, as well as under the left ribs. The right lower quadrant was noted to be constantly painful and tender. The diagnosis was some sort of acid peptic disease which is partially controlled with antacids, Sucralfate, Cimetidine and Gaviscon. An intestinal examination was also performed. He recounted experiencing 6 to 7 bowel movements per day. At times there was blood mixed with the stool. He was not anemic or malnourished. He noted that he occasionally had some constipation. Tests were negative for ova or parasites. The flexible sigmoidoscopy showed normal mucosa and random biopsies were within normal limits. The diagnosis was that he most likely suffered from irritable bowel syndrome, although there was a possibility that he harbored a pathogen that had not been discovered through conventional tests. VA outpatient treatment records developed between October 1993 and April 1994 noted that he continued to complain of suffering from 6 to 7 bouts of diarrhea each day. This was accompanied by abdominal cramping, gas, heartburn and belching. The impression was that his condition was beginning to sound like irritable bowel syndrome with alternating constipation and diarrhea with cramps and bloating. After a careful review of the evidence of record, it is the opinion of the undersigned that a 30 percent disability evaluation under Diagnostic Code 7319 is warranted. As noted above, a 30 percent disability under this code requires that there be severe irritable colon syndrome manifested by diarrhea, or alternating diarrhea and constipation, with more or less constant abdominal distress. The evidence in the case clearly shows that he experiences constant diarrhea, abdominal distress and pain. Hence, the disability picture presented here more closely approximates the higher disability evaluation under this code. 38 C.F.R. § 4.7 (1994). However, a 40 percent disability evaluation under Code 7305 for the veteran's ulcer disease is not warranted. The symptoms of this aspect of his gastrointestinal disability are no more than moderate in degree. He has not demonstrated impairment of health manifested by anemia and weight loss as required to justify a 40 percent disability rating. 38 C.F.R. § 4.112 (1994). While he does have symptoms associated with ulcer disease, and gastrointestinal reflux, the recent medical evidence does not show periodic vomiting or recurrent hematemesis or melena. Moreover, he has no evidence of incapacitating episodes averaging 10 or more days in duration at least four times a year. Therefore, a higher disability evaluation under this code is not justified. Nor does the evidence of record establish that an extraschedular evaluation is warranted under 38 C.F.R. § 3.321. The disability in question has not resulted in frequent periods of hospitalization. While this disability may contribute to his difficulties maintaining employment, it alone has not caused marked interference with employment. In conclusion, the evidence of record supports a finding of entitlement to a 30 percent disability evaluation for his peptic ulcer disease with spastic colon. D. Entitlement to a separate rating for a spastic colon. It has already been noted that, generally, the evaluation of the same disability under various diagnoses is to be avoided. Disability from injuries to the muscles, nerves, and joints of an extremity may overlap to a great extent, so that special rules are included in the appropriate bodily system for their evaluation. Dyspnea, tachycardia, nervousness, fatigability, etc., may result from many causes; some may be service connected, others, not. Both the use of manifestations not resulting from service connected disease or injury in establishing the service connected evaluation and the evaluation of the same manifestation under different diagnoses are to be avoided. 38 C.F.R. § 4.14 (1994). According to Esteban v. Brown, 6 Vet.App. 259 (1994), in determining whether a separate rating is justified, it must be determined that none of the symptomatology of the conditions in question is duplicative or overlapping. As has been clearly set forth in our grant of an increased rating for the veteran's gastrointestinal disability, there are symptoms of both ulcer disease and the irritable bowel or spastic colitis. The veteran stated during his September 1992 hearing that this condition has been identified as colitis and should, therefore, be service connected as a distinct disability. During his September 1994 personal hearing, he stated that the spastic colon symptoms had been present since service and should be separate from his duodenal ulcer disability. However, it is the opinion of the undersigned that assigning a separate evaluation for this disorder would violate the specific regulatory prohibition set forth in 38 C.F.R. § 4.114 (1994). The Board is bound by the regulations. The upper and lower gastrointestinal disabilities are rated under codes included in the range cited, from 7301 to 7329. We have, by this decision, rated the predominant disability picture, and assigned an increased rating under Diagnostic Code 7319 based on the more or less constant distress he experiences. We also found that the overall disability picture does not warrant elevation to the next higher evaluation, 40 percent under Diagnostic Code 7305, since the criteria are not met. Finally, the Schedule for Rating Disabilities contains express prohibitions against awarding separate ratings; in this instance, a rating under Code 7305 may not be combined (38 C.F.R. § 4.25 (1994)) with a rating under Code 7319. See Bierman v. Brown, 6 Vet. App. 125, 130; Crowley v. Brown, No. 92-1329 (U.S. Vet. App. Sept. 20, 1994). Accordingly, a separate rating for the irritable bowel/spastic colon disease must be denied. E. Entitlement to an increased evaluation for a right inguinal area scar. According to Diagnostic Code 7805, scars are to be rated based upon the limitation of function of the affected part. In the case of superficial scars a 10 percent disability evaluation is warranted for those that are poorly nourished with repeated ulceration, 38 C.F.R. Part 4, Code 7803 (1994), or which are tender and painful on objective demonstration. 38 C.F.R. Part 4, Diagnostic Code 7804 (1994). A review of the service medical records revealed that the veteran began to complain of a painful lump in the right inguinal area in July 1966. This was tender to palpation. By September 1966, right inguinal adenopathy was diagnosed. He continued to treated for this condition, and in July 1967, this node was dissected. His separation examination referred to bilateral hernia scars. The veteran was examined by VA in October 1969. This examination noted the presence of a one inch right inguinal scar, the result of the removal of a lymph node in service. No other findings in relation to this scar were noted. The diagnosis was scar, excision lymph nodes, right inguinal scar. A July 1976 VA examination noted bilateral groin scars. No tenderness, pain or ulceration was noted. The diagnosis was scar, post-operative, right inguinal area. The veteran testified at a personal hearing in September 1992 wherein he initially stated that he had had no trouble with his right inguinal scar. He then testified that all of the scars on his body were sensitive. He said that this right inguinal scar would often ache, although he referred to no specific treatment for this scar. After carefully reviewing all of the evidence of record, it is the opinion of the undersigned that a compensable evaluation for a right inguinal scar is not warranted. The evidence does not show that this scar is poorly nourished with repeated ulcerations, nor that is it painful and tender upon objective demonstration, as would be required to justify a 10 percent disability evaluation. While the veteran claimed during his September 1992 hearing that this scar was sensitive, the objective medical evidence does not substantiate this assertion. On the contrary, no objective findings were ever made as to this scar, except to note its existence. Therefore, it is concluded that the preponderance of the evidence is against the veteran's claim for entitlement to a compensable evaluation for his right inguinal scar. Nor does the evidence of record establish that an extraschedular evaluation is warranted under 38 C.F.R. § 3.321. The disability in question has not resulted in frequent periods of hospitalization. Nor is there any indication that this disability has caused marked interference with employment. In conclusion, a compensable evaluation for his right inguinal scar is not warranted. III. Secondary service connection claims Under the applicable criteria, service connection may be granted for disabilities which are proximately due to or the result of a service connected disease or injury. 38 C.F.R. § 3.310(a) (1994). A. Entitlement to a separate grant of service connection for right foot drop as secondary to service connected right peroneal neuritis. The veteran has claimed that he now suffers from right foot drop as a direct consequence of his right peroneal nerve injury. VA outpatient treatment records developed between July and October 1990 contained an August notation that the veteran had right foot drop and peroneal nerve hypesthesia. In September, foot drop from his peroneal nerve injury was noted. He was wearing a brace on this extremity. In October, he was noted to have right foot drop. During a September 1992 personal hearing, the veteran testified that he had had foot drop ever since the original injury, but that it had not been diagnosed until 1990. When asked if he could move his toes upward, he responded that his foot was bent inward. He asserted that he had to wear a brace to keep his foot immobile. He commented that his right ankle was completely useless, that he had no voluntary use of this joint. A VA examination was conducted in September 1993. The veteran's chief complaint was that he had foot drop. The physical examination reported that he had right foot drop. Plantar flexion was to 30 degrees and dorsiflexion was 0 degrees. The diagnosis was right foot drop secondary to peroneal nerve disease. The veteran underwent an extensive neurological examination performed by VA in January 1994. This examination noted that the veteran was wearing an in-shoe foot brace that extended to the knee; he stated that he wore this device to maintain stability in the right lower extremity. Plantar flexion was 5+ and dorsiflexion was 4+. Dorsiflexion of the foot in eversion and inversion was 4+ as well. The ankle reflex was absent on the right. The diagnosis stated that the veteran had some mild weakness of the right foot upon dorsiflexion, eversion and inversion. This would correlate with his complaints that his foot tends to turn in when he removes the foot brace. The past diagnoses of "foot drop" were noted. However, it was noted this diagnosis may not be fully appropriate considering the degree of strength he has and the lack of EMG evidence or visual evidence of changes in the right leg. A private physician noted in April 1994 that the veteran had right foot drop. This was allegedly related to his right peroneal nerve injury. In September 1994, the veteran testified at a personal hearing, at which time he reiterated his contention that he has had to wear a brace since the knee injury to prevent the foot from inverting. He went on to state that he was able to dorsiflex the right foot; in other words, he was able to raise it up. He then said that without the brace he is able to flex the foot but that he has no lateral control. In fact, without this foot brace he would fall. After carefully reviewing the evidence of record, it is the conclusion of the undersigned that entitlement to a separate grant of service connection for right foot drop secondary to his peroneal nerve injury is not warranted. Initially, we observe that while "foot drop" was diagnosed in the past, the recent and extensive VA neurological examination performed in January 1994 did not confirm this diagnosis. It was noted that the veteran did have some mild weakness on dorsiflexion, inversion and eversion of the right foot. This was noted to be consistent with his complaints that the foot "turns in" without a foot brace. However, the objective examination with the brace removed was not consistent with a diagnosis of foot drop. The veteran was noted to be able to dorsiflex and flex the right foot. Moreover, the motor strength tests revealed a degree of strength that would not be present if he had foot drop. Finally, the veteran admitted during his September 1994 personal hearing testimony that he was able to raise the foot upward. Clearly, the preponderance of the evidence is against a finding that the veteran actually has foot drop in the sense that the foot dangles and drops as a result of a lack of active muscle movement due to the peroneal nerve impairment. Further, the right foot impairment that is demonstrated is already service-connected, and we have recognized the severity of the disability by granting a 30 percent evaluation for the peroneal nerve injury residuals under the appropriate diagnostic code. Our finding of a severe, incomplete paralysis was based in large measure on the right foot impairment. To grant separate service connection for the peroneal nerve impairment of the right foot, and rate the right foot separately under a musculoskeletal or muscle injury code would be overlapping and duplicative of the manifestations now rated under the appropriate peroneal nerve code. 38 C.F.R. § 4.55(g) (1993). This would constitute pyramiding. 38 C.F.R. § 4.14 (1994). Accordingly, separate service connection and rating for the veteran's right foot (peroneal nerve) disabilities is not warranted. Bierman v. Brown, 6 Vet. App. 125 (1994); Crowley v. Brown, No. 92-1359 (U.S. Vet. App. Sept. 20, 1994). B. Entitlement to service connection for a right wrist disability as secondary to his service connected right lower extremity disabilities. A review of the record reveals that, while incarcerated in March 1990, the veteran slipped and fell in the shower, injuring his right wrist. A private treatment record from June 1990 indicated that he had either slipped on a substance on the floor or fell due to his leg giving out. The shower was not equipped with railings and the veteran fell on his outstretched arm. VA outpatient treatment records developed between July and October 1990 noted the history of the March 1990 fall. He was placed in several splints and a cast, but was placed in only a thumb spica from May to June 1990. The physical examination revealed positive snuff box tenderness and swelling; there was pain upon movement of the thumb and wrist. A July 1990 x-ray revealed a radiolucent shadow on the navicular, most likely due to a partial division of the navicular bone rather than a fracture. An August wrist tomogram showed no nonunion of the scaphoid, although snuff box tenderness was still present. A September x-ray, which provided a poor view, suggested that union was occurring. However, by October, it was noted that there was still nonunion with significant sclerosis. The physical examination revealed a tender snuff box and a tender radial tubercle. The assessment was healing dorsal scaphoid fracture. It had been suggested that the veteran had fallen because of his right leg. The veteran submitted statements from private physicians dated in January 1991. Each of these provided the opinion that the veteran experienced problems with ambulation due to his right lower extremity disability and that this disability caused him to fall frequently. It was also stated that he had developed reflex sympathetic dystrophy in the right wrist, which was noted to be an incapacitating disease. During a January 1991 examination, the veteran's right wrist was noted to be in a splint. There was minimal to no swelling. He was capable of performing 70 degrees of extension, 30 degrees of flexion, 35 degrees of ulnar deviation, and 15 degrees of radial deviation upon passive motion. Active motion revealed 45 degrees of extension and 25 degrees of flexion. Supination and pronation were limited. Grip strength was poor. The assessment was of weakness and decreased range of motion due to a long period of immobilization. The diagnosis was still unclear. In March, the splint had been removed, although he continued to complain of pain. A private EMG performed in April 1991 noted some weakness in the anterior interosseous nerve distribution, with mild abnormality of the muscle group supplied by the nerve. A May 1991 x-ray report revealed a tiny spur on the distal portion of the fifth distal phalanx. The June 1991 MRI report noted that a November 1990 MRI of the right wrist revealed no significant abnormality; the 1991 study revealed no evidence of reflex sympathetic dystrophy. A July 1991 physical examination noted that it was unlikely that the veteran was suffering from reflex sympathetic dystrophy (e.g., there were no pathogenic skin changes). However, he still complained of right elbow and wrist pain An MRI and a cervical thermogram were negative. No source for the elbow and scaphoid pain could be identified. Some improvement was noted in September, although he continued to refer to diffuse upper extremity pain. Again, it was noted that his symptoms were not characteristic of reflex sympathetic dystrophy. An October clinical examination mentioned his persistent complaints of upper extremity pain. There was acute pain over the snuff box and a positive Finkelstein's test. The shoulder displayed decreased range of motion but the right hand was not cold or discolored. It was felt that his major problems included tendonitis, medial and lateral epicondylitis, DeQuervain's tendonitis and infraspinatus tendonitis. Nerve conduction studies and EMG tests were consistent with posterior and anterior interosseous nerve dysfunction. VA outpatient treatment records from September to December 1991 revealed his continuing complaints of tenderness and numbness in the epicondyle area. The September clinical examination was not convincing for reflex sympathetic dystrophy. In October, decreased pinprick sensation was noted, as was tenderness over the lateral epicondyle. In December numbness on the right thumb and the right fifth finger were present. During a January 1992 personal hearing, the veteran stated that he was in the shower, which had no handrails, when his leg gave out. He attempted to catch himself; instead, he fell and broke his wrist. The veteran testified at another personal hearing in September 1992 wherein he again stated that he had fallen in the shower, suffering a right wrist fracture, because of the instability of his right leg. A March 1993 VA outpatient treatment record indicated that the veteran had a very complicated history of pain in the right wrist, elbow and hand. All tests provided negative results, although a provisional diagnosis of reflex sympathetic dystrophy had been made. He had decreased grip strength, and deep tendon reflexes were 2/4 bilaterally with complaints of pain upon elbow motion. An x-ray found no evidence of a fracture or of degenerative changes. The veteran was provided with an extensive VA examination performed in January and February 1994. The January neurological examination noted his complaints of numbness in the right arm, as well as discomfort. Motor testing revealed generalized weakness in this extremity at full flexion and extension. There was also mildly decreased sensation particularly in the first three digits of the right hand. An EMG study was normal. The diagnosis noted that these right upper extremity problems appeared to be secondary to the past right elbow and hand injuries. The physical examination showed that the veteran complained of tenderness to palpation over the dorsal radial wrist and at the first carpal metacarpal joint. He displayed 5/5 strength in the abductor pollicis longus and extensor pollicis longus muscles. Several past x-rays were reviewed and there was no evidence of previous fractures or dislocations. The diagnosis was chronic pain of the right distal radius and wrist joint of unclear etiology other than probable synovitis. After a careful review of the evidence of record, it is the opinion of the undersigned that entitlement to service connection for a right wrist disability secondary to the veteran's service connected right lower extremity disabilities is not warranted. The objective evidence of record supports a finding that the fall in March 1990 was not due to instability of either the right ankle or right knee joints. The evidence of record shows that, despite some inversion of the right ankle, the right ankle joint was fairly strong (as is evidenced by the January 1994 VA examination). Also, while he states that the right knee was subject to give way, there is no objective evidence to support this contention; no instability has been found on examination. The opinions of the private physicians that his fall was caused by his leg are noted; however, these opinions were based upon the history of the fall as provided by the veteran. We accept as most probative of the circumstances the earlier recorded history that he had either slipped on a substance on the floor or his leg had given out. Considering the fact that the veteran maintains good strength in the right lower leg, we are persuaded that the environment, a shower with a likelihood of a slippery floor, provides the best explanation of the cause of the fall. Therefore, it is concluded that the preponderance of the evidence is against the veteran's claim for service connection for a right wrist disability as secondary to his service connected right lower extremity disabilities. C. Entitlement to service connection for a low back disability secondary to the service connected right lower extremity disabilities. The veteran has contended that his right peroneal nerve injury has caused his leg to give way, resulting in back injuries. He asserts that these injuries resulted in a chronic back disability. Therefore, service connection should be granted. The objective evidence reveals that the veteran was admitted to a private hospital in August 1975 complaining of back and right leg pain. He stated that he had injured his back while at work on July 18, 1975. He recounted that he had fallen backwards, striking his back and his leg on a fare box on a bus. According to the veteran, he had never had any trouble with his back prior to this. Significantly, he made no mention of his fall being caused by his right lower extremity. In December 1980, the veteran suffered another back injury at the Post Office, his place of employment. He apparently slipped on some grease or water spillage. Again, no mention was made of his right lower extremity as a contributing factor in his fall. Throughout the 1980's, the veteran continued to complain about back pain. A January to February 1983 VA examination noted his contention that he had fallen in 1979 after his right leg gave out in him. In January 1991, the veteran's private physicians agreed with him that his right leg disability was responsible for the development of a back disorder. One reported that the veteran's abnormal gait had caused a back disability to begin. The other opinion reported that the veteran's back disability was related to his right peroneal nerve injury. In January 1992, the veteran testified at a personal hearing. He stated that at the time that he injured his back at the Post Office in December 1980, he had had trouble with his right leg giving out on him. He admitted that this fall had been caused by his slipping in some grease or water on the floor. However, he asserted that the fall was caused, at least in part, by his right leg difficulties. At his September 1992 hearing, the veteran alleged that both the 1975 and the 1980 falls had been the result of his right leg giving way. In April 1993, a private physician wrote that the veteran's abnormal gait, that was the result of his peroneal nerve injury, would increase the strain on his low back. This increasing strain would, in turn, result in chronic degenerative changes which would further compromise his back functioning. Finally, the veteran testified at a personal hearing before the Board in September 1994, at which time he stated that the record indicated that his abnormal gait, the result of the peroneal nerve injury, had caused his back to deteriorate. He also asserted that his peroneal nerve injury had aggravated his congenital stenosis. After carefully reviewing the evidence of record, it is the opinion of the undersigned that entitlement to service connection for a back disorder secondary to his service connected peroneal nerve injury is not warranted. Initially, it is noted that the veteran injured his back on two occasions, in 1975 and 1980, in falls that occurred at his places of employment. The exact cause of the 1975 fall was not indicated, other than he had fallen backwards and struck his low back and leg. However, what is significant is that, at the time of the August 1975 hospitalization for this injury, the veteran made no reference to being plagued by right leg instability that was resulting in falls, despite the fact that the time of treatment on the back would have been an ideal time to seek treatment for his leg. Moreover, no mention was made of the veteran suffering from an abnormal gait. The veteran then suffered an additional fall in 1980 at the Post Office. The record pertaining to this fall clearly indicates that he had slipped on either grease or water on the floor. No mention was made of an abnormal gait, nor did the contemporaneous record refer to right leg give way. The veteran's private physicians, in the late 1980's and 1990's, rendered their opinions that the veteran now suffers from degenerative changes in the back because of falls that occurred due to an abnormal gait and right leg give way caused by his right peroneal nerve injury. However, the contemporaneous records pertaining to these falls made absolutely no reference to right peroneal nerve injury symptoms as being the precipitating factors in his falls. Rather, each fall appeared to be caused by environmental factors. These physician's opinions were based upon history given by the veteran. The Board is not required to accept these opinions, where there are discrepancies regarding the injuries, and the opinions are based on the history provided by the veteran to the physician. Swann v. Brown, 5 Vet.App. 229, 233 (1993). It is therefore concluded that the objective evidence of record does not suggest that the residuals of the veteran's service connected right peroneal injury played any role in his low back injuries. In fact, no residuals of this service connected disability, such as an abnormal gait, were referred to at the time of the 1975 and 1980 injuries. While he may now suffer from degenerative changes, these changes, as well as any other chronic disability of the low back, appear more likely from the record to be the result of these injuries, which, as noted, were not related to his service connected right lower extremity disability. Therefore, it is concluded that the preponderance of the evidence is against the veteran's claim for service connection for a low back disability as the result of his service connected right peroneal nerve injury. IV. New and material evidence claims The applicable criteria state that a notice of disagreement shall be filed within one year from the date of mailing of the notification of the initial review and determination; otherwise, that determination will become final and is not subject to revision on the same factual basis. The date of the notification will be considered the date of mailing for purposes of determining whether a timely appeal has been filed. 38 U.S.C.A. § 7105 (West 1991); 38 C.F.R. §§ 3.104(a), 20.302 (1994). If new and material evidence is presented or secured with respect to a claim which has been disallowed, the Secretary shall reopen the claim and review the former disposition of the claim. 38 U.S.C.A. § 5108 (West 1991). "New and material evidence" means evidence not previously submitted to agency decisionmakers which bears directly and substantially upon the specific matter under consideration, which is neither cumulative nor redundant, and which by itself or in conjunction with evidence previously assembled is so significant that it must be considered in order to fairly decide the merits of the claim. 38 C.F.R. § 3.156(a) (1994). A. Whether new and material evidence has been submitted to reopen a claim of entitlement to service connection for a low back disability. Service connection may be granted for a disability the result of disease or injury incurred in or aggravated by service, 38 U.S.C.A. § 1110 (West 1991), or, when a veteran has served 90 days or more during a period of war, and arthritis becomes manifest to a compensable degree within one year following separation, such disease shall be presumed to have been so incurred, even though there is no evidence of such disease during the period of service. This presumption is rebuttable by affirmative evidence to the contrary. 38 U.S.C.A. §§ 1101, 1112, 1113 (West 1991); 38 C.F.R. §§ 3.307, 3.309 (1994). The evidence which was of record when the RO considered this issue in 1981 will be briefly summarized. The service medical records are completely silent as to any low back disability. While they refer to a neck and shoulder injury, no mention is made of the low back. A VA examination performed in October 1969 contained no reference to any complaints concerning the low back. The objective examination of the back was completely normal. A private hospital record from August 1975 revealed that the veteran was admitted after injuring his low back in a fall at his place of work. He noted that he had fallen backwards, striking his back against a fare box on a bus. He apparently twisted his back, developing severe back pain. According to the veteran he had had no back trouble prior to this injury. There were no radicular symptoms. The physical examination found tenderness to palpation in the right L5 to S1 area with mild paravertebral muscle spasm. Flexion was limited to 50 degrees, and extension was to 15 degrees. Straight leg raises were negative bilaterally. A neurological examination was within normal limits and x-rays revealed no definite bone or joint abnormality. The diagnosis was acute lumbosacral strain. A June 1976 VA examination, while containing an orthopedic examination of his right knee, made no mention of a back disability. In fact, all other joints were normal. A private outpatient treatment record from April 1981 noted his complaints of a backache that had developed three days before. In November 1981, the RO issued a rating action which denied entitlement to service connection for a back disability. This decision stated that the veteran's service medical records were completely silent as to any complaints of or treatment for a back disability. Moreover, the veteran had not been treated for a chronic back disorder following his discharge from service. Therefore, service connection was denied. The evidence submitted since the November 1981 denial of this issue included private treatment records developed between April 1981 and January 1983. In April 1981, the veteran alleged that he had injured his back in an explosion which destroyed a jeep in which he was riding. He said that he hurt his right leg and noticed the onset of mild low back pain. Since that time, he had fallen at the Post Office in December 1980, which had caused the back pain to worsen. The neurological examination revealed that he displayed sensory hypalgesia over the L5-S1 distribution on the right. There was mild tenderness over the sciatic notch and deep tendon reflexes were normal. The impression was lumbar nerve root compression to be ruled out. Throughout 1981 and 1982, the veteran continued to seek treatment for a painful low back. In 1981, he underwent a lumbar diskectomy. In November 1988, the veteran was examined by a private physician. Again, he reported the history of injuring his low back in an explosion in service. He stated that he exacerbated this injury in service when he was involved in a motor vehicle accident in 1969. His chief complaints revolved around pain in the low back, which radiated down the right side. A sensory examination revealed global hypalgesia throughout the entire right lower extremity. Diminished range of motion in the low back was noted. A CT scan revealed congenital stenosis, as well as marked degenerative stenosis. The impression was post- laminectomy syndrome. In August 1989, a private examination noted the veteran's complaint that he had developed burning pain and numbness in the left leg. His low back had decreased range of motion, although his reflexes were normal, save for the right ankle jerk, which was absent. A CT scan revealed congenital stenosis and facet hypertrophy which was causing a L5 root filling defect. The impression was recurrent pain, with a suggestion of S1 radiculopathy on the left. Numerous VA outpatient treatment records developed between May 1981 and July 1992 revealed the same type of complaints from the veteran. These records also contained his allegation that he had originally injured his back in an explosion in 1967, while serving in Vietnam. His low back pain, radiculopathy and limitation of motion were persistent. These problems were resistant to various type of treatment, including conservative therapies and surgical intervention. A July 1992 x-ray revealed a gross annular bulge at L4-5 on the left, transversing the left L5 neural nerve sleeve; a developmentally narrow spinal canal; and a small laminectomy defect on the right side without significant post surgical scarring. A March 1993 MRI found no evidence of disc herniation; rather, it noted the presence of enhancing scar tissue at the L4-5 and L5-S1 levels, and spinal stenosis at L2-3, predominantly congenital in nature. In April 1993, a private physician noted that the veteran had injured his back in December 1980 when he fell while working at the Post Office. This resulted in chronic back pain and the development of a herniated disc at the L4-5 level. It was noted that conservative treatment was tried; when this failed, a laminectomy was performed in 1982. In 1988, a car accident exacerbated his back pain. Tests showed spinal stenosis from L2 through L5, with post operative changes at L5 to S1. By 1989, S1 radiculopathy was suggested and limited range of motion was present. He had congenital narrowing of the spinal canal which was complicated by the development of a herniated disc at L4-5. In September 1993, the veteran's private physician noted the history of being injured in an explosion in 1968. The veteran was examined by VA in September 1993, at which time he complained of constant low back pain that radiated down the left leg more than the right. He displayed decreased sensation in the extremities. He had left lower extremity peripheral neuropathy secondary to marked discogenic disease. Range of motion studies were not done since he had marked instability without his cane. The diagnosis was L4-5 and L5-S1 congenital stenosis with a history of fasciectomy, laminectomy and diskectomy. The veteran underwent an extensive examination by VA in January and February 1994. During this examination he again stated that he had hurt his back in an explosion that occurred in 1967 or 1968 while he was in the military. The January 1994 neurological examination revealed complaints of bilateral leg numbness. Some mild spasm in the left paravertebral and lower sacral areas was noted. Straight leg raises were negative. Full range of motion was not possible due to instability. The sensory examination revealed generalized hypoesthesia over both legs but without any specific neurologic distribution. Vibratory sense was also decreased. The diagnosis noted that the veteran's lower extremity symptoms were difficult to explain. They were noted to be likely due to post laminectomy syndrome. There was no evidence of a major neurologic dysfunction. The orthopedic examination conducted in February 1994 diagnosed lumbar spine degenerative changes; status post L4-5 lumbar laminectomies, possible lateral transverse process fusion from L4-S1 with chronic lumbar mechanical back pain. A private physician noted in April 1994 that the veteran suffered from congenital spinal stenosis. He opined that this stenosis was aggravated by his period of service. After a careful review of the complete record, it is the opinion of the undersigned that the additional evidence which the veteran has submitted is not "new and material." Accordingly, his claim is not reopened and the Board's 1981 decision remains final. "New" evidence means more than evidence which was not previously physically of record. To be "new," additional evidence must be more than merely cumulative. Colvin v. Derwinski, 1 Vet.App. 171 (1991). The additional evidence presented in this case is only cumulative. The evidence previously of record indicated that the veteran never complained of a back injury in service, nor was he treated for one. A post service VA examination had found that the back was normal. The first notation of back pain was not noted until after he injured his back at work in 1975. Even so, a VA examination performed in 1976 found the back to be normal. The evidence submitted after the 1981 denial, while containing his unsubstantiated history of suffering a back injury during an explosion in 1967, show nothing more. These records do not establish, through objective evidence, that he ever experienced an injury in service. Moreover, these records do not show that any degenerative changes in the low back were present to a compensable degree within one year of his separation. Similarly, the additional evidence is not "material." Assuming, without deciding, that the additional evidence is relevant and probative, there is no reasonable possibility that the additional evidence, when viewed in context with all the evidence, both old and new, would change the outcome. See Colvin and Smith v. Derwinski, 1 Vet.App. 178 (1991). The additional evidence contains no objective proof that the veteran suffered a back injury in service, nor does it establish that any arthritic condition manifested to a compensable degree within one year following discharge. The service medical records leave no doubt that no back injury was ever complained of by the veteran. These records are absolutely silent as to back injury. While the veteran has alleged that he was injured in an explosion in 1967, the objective record does not corroborate this. What the record does show is that he injured his low back in 1975 after falling at work. He re-injured his back in 1980 when he slipped on a wet surface at his job with the Post Office. It was after these two events that the veteran began to suffer from chronic low back pain. Moreover, none of the evidence suggests that degenerative changes were present to a compensable degree by June 1970 (one year after his separation). It has been noted that the veteran has congenital stenosis of the lower spine. However, this is a developmental defect for which service connection cannot be granted by regulation. 38 C.F.R. § 3.303(c) (1994). Therefore, it is found that the veteran has submitted no objective evidence that would tend to link his current back disability to an event in service. It is the conclusion of the undersigned that new and material evidence which would serve to reopen this claim has not been submitted. B. Service connection for PTSD. In order to establish entitlement to service connection for PTSD, there must be medical evidence establishing a clear diagnosis of the condition, credible supporting evidence that the claimed inservice stressor actually occurred, and a link, established by medical evidence, between current symptomatology and the claimed inservice stressor. 38 C.F.R. § 3.304(f) (1994). After carefully reviewing the evidence of record, it is the conclusion of the undersigned that the evidence submitted since the October 1983 decision by the RO is new and material. The evidence submitted, numerous medical records and a statement from the Environmental Support Group, includes new and material evidence. That is, it is evidence which has not previously been considered and which is relevant and probative of the issue being considered. Colvin v. Derwinski, 1 Vet.App. 171 (1991). It is apparent that this evidence, when viewed in the context of all the evidence of record, might change the outcome of the decision. Given this determination, the claim is reopened and the entire evidence of record must be considered in determining whether entitlement to service connection is warranted. The record revealed that the veteran's primary occupation during his period of service was as a military police officer. He received three National Defense Service Medal, the Vietnam Service Medal, and the Republic of Vietnam Campaign Medal. There is no indication that he received any combat badges. A review of the service medical records revealed no complaints of or treatment for a psychiatric disorder. After service, the veteran underwent a psychiatric evaluation by VA in June 1983. During this examination, he stated that he witnessed some terrible things while he was stationed in Vietnam. He stated, for example, that his best buddy had had his head shot off and that he had gotten splattered with the blood. He said that he saw children shot which, to his consternation, he had begun to enjoy. The mental status examination revealed that he was a plethoric person, with no delusions or hallucinations. He reported poor sleep, that was plagued by dreams of Vietnam. He was moody and short-tempered. It seemed obvious to the examiner that the veteran had post traumatic stress neurosis. VA outpatient treatment records developed between June 1990 and February 1991 revealed that in June 1990 he recounted experiencing anger and violent episodes. These episodes were related to events that occurred in Vietnam. The assessment was adjustment disorder with depressed mood versus major affective disorder; rule out PTSD. On November 8, 1990, he complained of sleep problems. He stated that he had been an MP in the service and that his duties varied. He reported an incident when he was supposed to go on patrol; however, he was not feeling well and a buddy replaced him. The jeep that they were riding in was hit with mortar fire and the men were killed. The veteran said that he was on the patrol that found their bodies. He also said that he saw combat in the TET offensive. He felt that he should have died in Vietnam. The mental status examination noted that his speech was well organized and that he displayed no evidence of psychotic disorganization. There were suicidal thoughts present, but there was no intent. He also had thoughts of harming others, but had no intent of doing so. He commented that he avoided any materials, particularly movies, that would remind him of the war. He also reported survival guilt. The assessment was of symptoms consistent with PTSD. On the November 16, it was noted that his War Stress Inventory results were also consistent with a finding of PTSD. The assessment was severe PTSD and alcohol abuse. On December 5, he noted that he was increasingly irritable and experiencing combat content nightmares. He was placed on Clonazepam and was advised against alcohol use. On February 11, 1991, he reported to his session with complaints of agitation, depression and nervousness. He displayed the same symptoms of PTSD. He recounted increased agitation, and more recall of Vietnam experiences. He also complained of a startle response. It was noted that therapy had brought out and somewhat worsened some of his PTSD symptoms. He apparently suffered from gruesome nightmares. He was demanding, argumentative, angry, and had a problem with authority. He was preoccupied with Vietnam, but because he felt that he could not talk to anyone about it, he felt isolated. The diagnoses were major affective disorder, severe PTSD; and rule out personality disorder. In January 1992, the veteran testified at a personal hearing. He reiterated that he was an MP during the war. He said that he would patrol villages and would sometimes guard POW's. There were daily encounters with the enemy, through sniper fire and rocketing of the camp. He repeated the incident where two friends had been killed when their jeep was destroyed. He stressed that it was supposed to be him in that jeep going on patrol, not his friend. He also stated that a friend, Billy Bird, had his head blown off, an incident that he witnessed. He said that the ammunition dump that was across from his camp was blown up during the TET offensive. He reported helping with body bags during the battle (he vividly recalled the blood sloshing inside the bags). After service, he reported developing an attitude and a drinking problem. He experienced survival guilt, depression, anger, anxiety, nightmares, flashbacks and a startle response. Between February 1991 and April 1993, the veteran continued to receive treatment from the VA. Throughout 1991, he was seen for depression and irritability. These symptoms would occasionally improve, but were easily aggravated, particularly by the Persian Gulf War. In April 1992, it was noted that he had made very little physical or emotional progress. In May 1992, he reported dreams and nightmares of a violent nature. He was prone to violent verbal outbursts and had a depressive affect. In June, his primary issues revolved around anger, agitation and intrusive PTSD symptoms relating to combat experiences. The diagnoses were PTSD, depression, and a mixed personality disorder. In July 1993, the Environmental Support Group was asked to confirm the veteran's reported stressors. Their correspondence confirmed that the 97th Artillery Group's camp was subjected to enemy mortar attack on the night of November 5, 1967. This roughly coincided with the testimony of the veteran. Moreover, the Long Binh area, where the veteran was stationed, was subject to significant combat actions during the TET offensive. Further, this report confirmed the veteran's statement that the Ling Binh ammunition depot was attacked by enemy forces resulting in the destruction of several pads of ammunition. The destruction of the jeep in October to November 1967 could not be confirmed, although the records did confirm that a "Bill Bryd" had been killed on November 11, 1967. The veteran was then examined by VA in October 1993. While he conceded that he was not involved in daily combat, he stated that he did have combat exposure. His symptoms included nightmares, difficulty sleeping, sweats, jumpiness at loud noises, intrusive thoughts, anger, irritability, rage attacks, distrust of people, and social withdrawal. The mental status examination showed that he had an angry affect, which was also somewhat resigned and sad. His mood was depressed and angry. His speech was clearly articulated and normal in rate rhythm, tone and form. There was no overt psychosis, hallucinations or delusions. There was also no current suicidal or homicidal ideation. The diagnosis was moderate to severe PTSD. His increasing physical problems were making it more difficult for him to cope with stress, thus exacerbating his PTSD. In July 1994, correspondence was received from his treating VA psychologist. It was noted that the veteran had been in treatment for four years. After extensive evaluation, it was the opinion of the author that the veteran had primary PTSD, secondary depression and a personality disorder. He experienced documented recurrent morbid and gruesome nightmares about Vietnam combat experiences, increased anxiety, social withdrawal, alienation, outbursts of anger and violent feelings. He also suffered from survivor guilt. In September 1994, the veteran testified at a personal hearing before the Board. He stated that he has a diagnosis of PTSD, which should be enough to entitle him to service connection. He also commented that his statements about his stressors had been consistent throughout the years, thus adding to their credibility. After carefully reviewing the record, it is the opinion of the undersigned that entitlement to service connection for PTSD has been established. The evidence of record indicates that, while the veteran was not involved in direct combat, he did suffer through traumatic events that would be markedly disturbing to anyone. The Environmental Support Group (ESG) confirmed that the veteran's unit was present at the locations that he indicated and that the events that he described, such as the destruction of the ammunition depot, did take place. The veteran had indicated that a friend named Billy Bird had been killed; the ESG confirmed that a Bill Bryd was killed in November 1967. While all of the specific information provided by the veteran, such as loading body bags, could not be confirmed, the information provided by the ESG was consistent with the general information given by the veteran. Therefore, giving the veteran the benefit of the doubt, the veteran did experience the requisite stressors during his tour of duty to support a diagnosis of PTSD. Moreover, he has several confirmed post-service diagnoses of this disorder, demonstrating numerous symptoms consistent with this disability. In conclusion, it is found that the evidence supports a finding of entitlement to service connection for PTSD. V. Entitlement to a total disability evaluation due to individual unemployability. According to the applicable laws and regulations, disability evaluations are determined by the application of a schedule of ratings which is based on the average impairment of earning capacity. 38 U.S.C.A. § 1155 (West 1991). Total disability ratings for compensation may be assigned where the schedular rating for the service connected disability or disabilities is less than 100 percent when it is found that the service connected disabilities are sufficient to produce unemployability without regard to advancing age. 38 C.F.R. §§ 3.340, 3.341, 4.16 (1994). The record indicates that the veteran has undergone training as a police officer, and worked as such until 1988. He also had obtained a contractor's license, and had training in drafting. Service connection is in effect for a duodenal ulcer with spastic colon, and right peroneal neuritis, each assigned a 30 percent disability evaluation. A right knee disability has been assigned a 10 percent disability rating. A noncompensable evaluation is in effect for a right inguinal area scar. He has a combined evaluation of 60 percent. He is also service connected, by this decision, for PTSD. He is receiving Social Security benefits due to his disabilities. The evidence of record includes a 1983 report from a private physician which noted that his physical limitations, including his right peroneal neuritis and the subsequent foot disability, rendered him unable to return to work in any capacity for an indefinite period. In January 1991, there was a note in his VA outpatient treatment records that he was 100 percent disabled. During a September 1992 personal hearing, the veteran stated that he had been completely disabled since 1988. He said his various disabilities have rendered him unemployable. A private physician in March 1993 noted that he was functionally unemployable; therefore, he was found to be totally and permanently disabled. A private vocational evaluation performed in April 1993, noted that the veteran spent most of his time at home, reading. He apparently had extensive training, including a contractor's license, drafting and the police academy. He appeared to be highly motivated to seek training to maintain employment, but could no longer do so because of his disabilities. In April 1994, his private physician noted that he was permanently and totally disabled, primarily due to his PTSD. After a careful review of the evidence of record, it is the opinion of the undersigned that the veteran's service connected disabilities have rendered him unable to secure or follow any substantially gainful occupation. The record indicates that the veteran is totally disabled by his PTSD alone, which, as part of this decision, has been service connected. He is plagued by anger, depression, nightmares, intrusive thoughts of Vietnam, rage attacks, social withdrawal, and distrust of people. This disability is severe in nature based on the medical assessments of record and has resulted in a significant degree of impairment upon his ability to work. Furthermore, he is unable to engage in any type of employment that would require physical labor due to his right peroneal neuritis and his right knee disorder. Despite his past willingness to seek additional training, and while he does have transferable skills, the current medical assessments are to the effect that he could not maintain substantially gainful employment for which he would be qualified by prior experience. Under the circumstances, it is the conclusion of the undersigned that the veteran is entitled to a total disability evaluation based on individual unemployability due to service connected disabilities. VI. Whether clear and unmistakable error was committed in 1981 and 1983, which denied service connection for a low back disability and PTSD, respectively. Service connection may be granted for a low back disability, to include arthritis, if it was incurred in or aggravated by service, or if arthritis develops to a compensable degree within one year of separation therefrom. 38 U.S.C.A. §§ 1101, 1110, 1112, 1113, (West 1991); 38 C.F.R. §§ 3.307, 3.309 (1994). It is further noted that the law grants a period of one year form the date of the notice of the result of the initial determination for initiating an appeal by filing a notice of disagreement; otherwise, that determination becomes final and is not subject to revision on the same factual basis in the absence of clear and unmistakable error. 38 U.S.C.A. § 7105 (West 1991); 38 C.F.R. § 3.105(a) (1994). In regard to the low back disability, it is noted that the service medical records were completely silent as to any complaints of or treatment for a low back disability. A VA examination conducted in October 1969 contained no complaints referable to the low back. The objective examination revealed that the back was within normal limits. There was no indication in the file of a back disability until 1975. In August of that year, the veteran reported to private hospital complaining of back pain after suffering a fall at work. He indicated at that time that he had had no back trouble prior to this incident. The physical examination revealed pain, and limitation of motion. However, an x-ray was negative. The diagnosis was acute lumbosacral strain. There was no mention of any follow-up treatment following his hospital discharge. A June 1976 VA examination found that his back was clinically normal. He then re-injured his back in December 1980, after slipping and falling at work at the Post Office. The veteran testified in September 1992 that he had originally injured his low back in the military in 1969, and that he re- injured it in 1975 and 1980. However, he reiterated that this back disability had begun in service. After carefully reviewing this evidence, it is the opinion of the undersigned that the November 1981 rating decision was not clearly and unmistakably erroneous. The evidence has revealed that the decision in 1981 to deny service connection for a back disability was a reasonable exercise of rating judgment. The evidence in the record at the time of the 1981 decision did not support a grant of service connection. Rather, it showed that a back disability was not present in service, and that any pre- existing stenosis was not aggravated by such service, as is evidenced by the complete lack of any inservice complaints. The evidence revealed that the veteran injured his back post-service, in 1975 and 1980. There was also no indication in 1981 that the veteran developed arthritis within one year of his separation from service. While the veteran's contention that he initially injured his back in service has been considered, it is not supported by the objective evidence of record. The denial in 1981 was consistent with the evidence in the file at that time and was thus not erroneous. In regard to the PTSD claim, the evidence in the file in October 1983 included the service medical records which were silent as to any complaints of or treatment for a psychiatric disorder. Following his discharge from the military, the veteran was examined by VA in June 1983. The report indicated that the veteran reported witnessing terrible things in Vietnam. He reported seeing a friend's head blown off. He complained of having sleep difficulties, as well as trouble controlling his temper. The mental status examination revealed that he had no delusions or hallucinations, although he reported frequent dreams about the war. He was moody and hot tempered. The examiner reported that it seemed obvious that the veteran had a post traumatic neurosis. At a September 1992 personal hearing, the veteran stated that he had been diagnosed with PTSD by VA psychiatrist. However, he asserted that the 1983 rating action ignored this diagnosis and denied the claim. Since that time, he reported being consistently treated for and diagnosed with PTSD. After a careful review of the evidence, it is the opinion of the undersigned that the October 1983 rating decision denying service connection was not clearly and unmistakable erroneous. The evidence in the record at the time of this decision indicated that the veteran was psychiatrically normal during service. There was no evidence of any psychiatric difficulties until the June 1983 VA examination. The examiner stated at that time that it appeared obvious that the veteran had a post traumatic neurosis. However, no stressors were developed, nor was any testing performed to confirm the diagnosis. Therefore, the evidence did not substantiate the diagnosis. The decision to deny the claim, based upon this evidence, was a reasonable exercise of rating judgment. An unconfirmed diagnosis, without evidence of stressors, is an insufficient basis upon which to grant service connection for PTSD. Therefore, it is the conclusion of the undersigned that the October 1983 rating action was consistent with the evidence then in the file and thus was not erroneous. VII. Whether the veteran is eligible for financial assistance in acquiring an automobile or other conveyance or special adaptive equipment. According to the applicable criteria, a certificate of eligibility for financial assistance in the purchase of one automobile or other conveyance will be provided any eligible veteran or service member whose service connected disability includes one of the following: loss or permanent loss of use of one or both feet; or loss or permanent loss of use of one or both hands; or permanent impairment of vision of both eyes to the required specified degree. 38 U.S.C.A. §§ 3901, 3902 (West 1991); 38 C.F.R. § 3.808 (1994). 38 U.S.C.A. § 1114(k) provides additional monthly compensation for loss of use of a foot. The term "loss of use" is defined by regulation as that condition where no effective function remains other than that which would be equally well served by an amputation stump at the site of election below the knee with use of suitable prosthetic appliance. The determination will be made on the basis of the actual remaining function, whether the acts of balance, propulsion, etc., could be accomplished equally well by an amputation stump with prosthesis. Complete paralysis of the external popliteal nerve (common peroneal) and consequent foot drop will be taken as loss of use of the foot. 38 C.F.R. §§ 3.350(a)(2), 4.63 (1994). Initially, it is noted that the veteran does not have service connected eye or hand disabilities. Nor, as explained below, does he meet the regulatory definition of loss of use of the right foot. In October 1990, the veteran was evaluated for hand controls by VA. It was noted that, with his history of nerve root compression, low back pain and right lower extremity numbness, hand controls were necessary. The veteran does have a neurological deficit involving the right lower extremity. This includes some inversion of the right foot. There have been some past diagnoses of foot drop. However, according to the January 1994 VA examination, the veteran had some mild weakness of the right foot in dorsiflexion, inversion and eversion, which was confirmed by EMG studies. These findings were noted to be consistent with his complaints that, without his brace, his foot would turn inwards. The diagnosis of foot drop was noted to be not fully appropriate given the strength he had in the foot, as well as by the lack of EMG evidence and visual evidence of changes in the right leg. The veteran testified at hearings in January and September 1992. During each hearing, he stated that he had applied for adaptive equipment, and that he had been told by VA physicians that he needed hand controls in order to drive safely. He stated that his right leg and back conditions required that he obtain this equipment. A private physician wrote in April 1994 that the veteran required adaptive equipment. The veteran then testified at an additional hearing in September 1994, wherein he reiterated his need for hand controls because it was becoming impossible for him to drive without them. He asserted that his back and peroneal neuritis necessitated obtaining this special equipment. Moreover, he noted that a handicapped license plate had been authorized by his state. After carefully reviewing the evidence of record, it is the opinion of the undersigned that the veteran is not entitled to financial assistance in obtaining special adaptive equipment for his automobile. Initially, it is noted that disability caused by his low back disorder is not for consideration, since this is not a service connected disability. While the veteran does have a neurological disorder involving the right lower extremity, it is the conclusion of the undersigned that this disability has not resulted in loss of use of this extremity, as is required to justify assistance in obtaining adaptive equipment. The term "loss of use" is defined by regulation as that condition where no effective function remains other than that which would be equally well served by an amputation stump at the site of election below the knee with use of suitable prosthetic appliance. The determination will be made on the basis of the actual remaining function, whether the acts of balance, propulsion, etc., could be accomplished equally well by an amputation stump with prosthesis. Complete paralysis of the external popliteal nerve (common peroneal) and consequent foot drop will be taken as loss of use of the foot. The objective evidence of record indicates that the veteran has not suffered loss of use of the right lower extremity. The VA examination has shown that the veteran is able to plantar flex this foot, although it is slightly limited. Muscle strength was assessed, and remains good in the right leg. It cannot be said that there is so little remaining function of the right extremity that he would be equally well served by an amputation stump below the knee with appropriate prosthetic. While he cannot dorsiflex beyond the 0 degree plane, the evidence does not demonstrate that there is complete paralysis of the right foot, with consequent foot drop. While the veteran's foot tends to invert upon walking, the objective examination of January 1994 does not show that active motion of the right ankle joint is absent. There were movements present, although some mild weakness was noted. In addition, the veteran's September 1994 personal hearing testimony leaves no doubt that he does not experience foot drop as the result of his peroneal neuritis. While he has some difficulty with the foot turning inward, which requires the wearing of a foot brace, he is able to raise the foot up and down. In fact, the VA examination noted that he actually had a considerable amount of strength in the foot, as well as no EMG evidence of foot drop. In conclusion, it is found that the veteran does not have loss of use of a foot, as is required to warrant financial assistance in acquiring special adaptive equipment. Therefore, the preponderance of the evidence is against the veteran's claim. VIII. Entitlement to an earlier effective date for the grant of service connection for residuals of a right knee injury. The veteran had raised a claim for entitlement to an earlier effective date for the grant of service connection for peroneal neuritis, which has been rated as a residual of the right knee injury. He stated that he had injured the right leg in service and had suffered from neurological symptoms since that time. He filed his claim for this disability within one year following his separation and has argued that service connection should have been granted effective the day following his discharge. In April 1994, the RO issued a rating action which stated that the VA examinations that had been conducted in 1969 and 1976 had made no neurological findings. The veteran complained of numbness during a June 1979 examination. It was noted that the veteran had originally been service connected for right knee injury residuals, assigned a noncompensable evaluation from March 31, 1976. His disability was reclassified as right peroneal neuritis, residuals of a right knee injury, and a 10 percent evaluation was assigned, effective December 2, 1980. It was found that the assignment of service connection for peroneal neuritis effective December 2, 1980 was correct, for this was the first time that it could reasonably be shown to have existed. However, it was found that the rating action dated in July 1976 was clearly and unmistakably erroneous in not establishing service connection for right knee injury residuals effective from the day following separation from service. It was stated that a VA examination in 1969 had noted the residuals of the right knee sprain suffered in service. Therefore, it was found that service connection for the residuals of a right knee injury should have been effective from June 20, 1969. According to 38 U.S.C.A. § 7105(d)(5) (West 1991), the Board may dismiss any appeal that fails to allege specific error of fact or law in the determination being appealed. In the instant case, the veteran had requested that an earlier effective date be assigned to the right knee injury residuals. This was granted by the rating action issued in April 1994. In fact, the effective date for service connection was made the day following his date of discharge; that is, June 20, 1969. This is the date requested by the veteran. Therefore, this appeal is dismissed, as the benefit sought on appeal by the veteran has been granted. It is again pointed out that the new issue of assignment of a compensable evaluation effective from June 20, 1969, has been referred to the RO for adjudication. ORDER Service connection for a skin disorder claimed as a residual of exposure to herbicides in Vietnam (or Agent Orange) is denied. Service connection for retained foreign bodies in the right elbow is denied. Service connection for residuals of trauma to the right eye is denied. A 30 percent disability evaluation for duodenal ulcer disease with spastic colon is granted, subject to the laws and regulations governing the award of monetary benefits. A compensable evaluation for a right inguinal area scar is denied. A 30 percent disability evaluation for right peroneal nerve injury residuals is granted, subject to the laws and regulations governing the award of monetary benefits. A separate 10 percent disability evaluation for residuals of injury to the right knee is granted, subject to the laws and regulations governing the award of monetary benefits. A separate grant of service connection for right foot drop secondary to service-connected right peroneal nerve neuritis is denied. Service connection for a right wrist disability as secondary to service-connected right lower extremity disabilities is denied. Service connection for a low back disability as secondary to service-connected right lower extremity disabilities is denied. New and material evidence not having been submitted to reopen a claim of entitlement to service connection for a low back disability, the benefit sought on appeal is denied. Service connection for PTSD is granted. A total disability evaluation based upon individual unemployability is granted, subject to the laws and regulations governing the award of monetary benefits. Clear an unmistakable error not having been found in a rating decision in November 1981 which denied entitlement to service connection for a back disability, the appeal is denied. Clear and unmistakable error not having been found in a rating decision in October 1983 which denied entitlement to service connection for PTSD, the appeal is denied. Eligibility for financial assistance in acquiring an automobile or other conveyance or special adaptive equipment is denied. The appeal for an earlier effective date for service connection of the residuals of a right knee injury is dismissed. Separate service connection for a spastic colon is denied. KENNETH R.
