REPRESENTATION Veteran represented by: Sean A. Ravin, Esq. WITNESS AT HEARING ON APPEAL The Veteran ATTORNEY FOR THE BOARD S. Bush, Counsel INTRODUCTION This matter comes before the Board of Veterans' Appeals (Board) on appeal from April 2005 and October 2006 rating decisions issued by the Department of Veterans Affairs (VA) Regional Office (RO) in Cleveland, Ohio. Procedural history The earlier effective date claim The Veteran served on active duty in the United States Army from September 1979 to June 1982. Service connection for a cervical spine disability was granted in a September 1982 rating decision. The Veteran filed a claim for an increased disability rating on August 10, 1992. A January 1993 rating decision increased the Veteran's cervical spine disability to 20 percent disabling effective August 6, 1992, the date of a private medical record evidencing increased symptoms. The Veteran perfected an appeal as to the disability rating assigned. After numerous remands and an appeal to the United States Court of Appeals for Veterans Claims (the Court), the Board eventually awarded a 60 percent disability rating for the service-connected cervical spine disability in a May 2006 decision. An October 2006 rating decision implemented the Board's findings, assigning a 60 percent rating effective December 1, 1997. The Veteran indicated his disagreement with the effective date assigned. The depression and TDIU claims In July 1999, the Veteran filed a claim of entitlement to service connection for depression as secondary to the service-connected cervical spine disability. The claim was denied by the RO in a May 2002 rating decision, which the Veteran did not appeal. In May 2003, the Veteran requested to reopen the previously- denied claim for depression; he also sought TDIU. These claims were denied in an April 2005 rating decision, and the Veteran perfected an appeal of that decision. In May 2006, the Board remanded the claims for additional evidentiary and procedural development. In August 2008, the Board requested an opinion from an independent medical expert (IME) as to the claim for depression. See 38 U.S.C.A. § 7109 (West 2002); 38 C.F.R. § 20.901 (2008). The opinion has been provided and it is associated with the Veteran's VA claims folder. FINDINGS OF FACT 1. The competent medical evidence of record supports a finding that a relationship exists between the Veteran's currently diagnosed depression and his service-connected cervical spine disability. 2. The competent medical evidence of record supports a finding that the Veteran's service-connected cervical spine disability and depression render him unable to secure or follow a substantially gainful occupation. 3. An unappealed June 1989 rating decision assigned a 10 percent disability rating for the service-connected cervical spine disability. 4. On August 10, 1992, the RO received the Veteran's claim for an increased rating for the service-connected cervical spine disability. 5. The RO subsequently granted an increased disability rating of 60 percent for the cervical spine disability, effective December 1, 1997. 6. The competent medical evidence of record indicates that cervical spine symptomology consistent with the assignment of a 60 percent rating was initiall identified on December 1, 1997. CONCLUSIONS OF LAW 1. Service connection for depression is warranted. 38 C.F.R. § 3.310 (2008). 2. The criteria for a total disability rating based on individual unemployability due to service-connected disability have been met. 38 U.S.C.A. § 1155 (West 2002); 38 C.F.R. §§ 3.340, 3.341, 4.16, 4.19 (2008). 3. The requirements for an effective date earlier than December 1, 1997 for the assignment of a 60 percent disability rating for service-connected cervical spine disability have not been met. 38 U.S.C.A. §5110 (West 2002); 38 C.F.R. § 3.400 (o) (2008). REASONS AND BASES FOR FINDINGS AND CONCLUSIONS The Veteran seeks service connection for depression as secondary to his service-connected cervical spine disability as well as entitlement to TDIU. He further contends that an effective date earlier than December 1, 1997 is warranted for the assignment of a 60 percent disability rating for the service-connected cervical myositis with disc disease, status post C5-6 interbody fusion. In the interest of clarity, the Board will first discuss certain preliminary matters. The issues on appeal will then be analyzed and a decision rendered. The Veterans Claims Assistance Act of 2000 (VCAA) The Board has given consideration to the VCAA. The VCAA includes an enhanced duty on the part of VA to notify a claimant as to the information and evidence necessary to substantiate a claim for VA benefits. The VCAA also redefines the obligations of VA with respect to its statutory duty to assist claimants in the development of their claims. See 38 U.S.C.A. §§ 5103, 5103A (West 2002). The Board is granting the Veteran's claims of entitlement to service connection for depression and TDIU. Accordingly, any failure to provide complete notice or assistance under the VCAA in the development of these two claims has been rendered moot and no further discussion is therefore necessary. With respect to the earlier effective date claim, the Board finds that no VCAA notice is necessary. Specifically, in Manning v. Principi, 16 Vet. App. 534 (2002), citing Livesay v. Principi, 15 Vet. App. 165 (2001), the Court held that the VCAA has no effect on an appeal where the law, and not the underlying facts or development of the facts, is dispositive of the matter. The Board finds that such is the case as to the issue here on appeal. The facts in this case, which involves the assignment of an effective date, are not in dispute. Application of pertinent provisions of the law and regulations will determine the outcome. No amount of additional evidentiary development would change the outcome of this case; therefore no VCAA notice is necessary. See DelaCruz v. Principi, 15 Vet. App. 143, 149 (2001) [VCAA notice not required where there is no reasonable possibility that additional development will aid the claimant]. Specifically, the Court has held that a Veteran claiming entitlement to an earlier effective date is not prejudiced by failure to provide him with VCAA notice of the laws and regulations governing effective dates, if, based on the facts of the case, entitlement to an earlier effective date is not shown as a matter of law. See Nelson v. Principi, 18 Vet. App. 407, 410 (2004). In addition, general due process concerns have been satisfied in connection with this appeal. See 38 C.F.R. § 3.103 (2008). The Veteran has been accorded ample opportunity to present evidence and argument in support of his appeal. He has retained the services of private counsel, who has presented argument on his behalf. As noted in the Introduction, he testified before the undersigned in December 2005. 1. Entitlement to service connection for depression, claimed as secondary to service-connected cervical myositis with disc disease, status post C5-6 interbody fusion. Relevant law and regulations Secondary service connection Service connection may be granted for a disability that is proximately due to, the result of, or aggravated by a service-connected disability. See 38 C.F.R. § 3.310(a) (2008); see also Harder v. Brown, 5 Vet. App. 183, 187 (1993). Additional disability resulting from the aggravation of a non-service-connected condition by a service-connected condition is also compensable under 38 C.F.R. § 3.310(a). See Allen v. Brown, 7 Vet. App. 439, 448 (1995). In order to establish service connection for a claimed disability on a secondary basis, there must be (1) medical evidence of a current disability; (2) a service-connected disability; and (3) medical evidence of a nexus between the service-connected disease or injury and the current disability. See Wallin v. West, 11 Vet. App. 509, 512 (1998). Standard of review In general, after the evidence has been assembled, it is the Board's responsibility to evaluate the entire record. See 38 U.S.C.A. § 7104(a) (West 2002). When there is an approximate balance of evidence regarding the merits of an issue material to the determination of the matter, the benefit of the doubt in resolving each such issue shall be given to the claimant. See 38 U.S.C.A. § 5107 (West 2002); 38 C.F.R. § 3.102 (2008). In Gilbert v. Derwinski, 1 Vet. App. 49, 53 (1990), the Court stated that "a veteran need only demonstrate that there is an 'approximate balance of positive and negative evidence' in order to prevail." To deny a claim on its merits, the preponderance of the evidence must be against the claim. See Alemany v. Brown, 9 Vet. App. 518, 519 (1996), citing Gilbert, 1 Vet. App. at 54. Analysis As noted above, in order to establish service connection for a claimed disability on a secondary basis, there must be (1) medical evidence of a current disability; (2) a service- connected disability; and (3) medical evidence of a nexus between the service-connected disease or injury and the current disability. See Wallin, supra. With respect to Wallin element (1), medical evidence of a current disability, there are numerous diagnoses of depression of record. With respect to Wallin element (2), a service-connected disability, the Veteran is currently service connected for cervical myositis with disc disease, status post C5-6 interbody fusion. Wallin element (2) is accordingly satisfied. [The Board observes in passing that the Veteran is also service-connected for frostbite residuals of the hands; however, his contentions concern only the cervical spine disability]. With respect to Wallin element (3), the Board sought an IME opinion to address the potential relationship between the Veteran's depression and his cervical spine disability. See 38 U.S.C.A. § 7109 (West 2002). The IME opined that "it is as likely as not that the Veteran's depression was caused at least in part by the service-connected cervical spine disorder." This finding is consistent with the October 1999 and November 2004 VA examination reports and the October 2002 statement of E.C.L., M.D. Wallin element (3) is therefore also satisfied. Because all three elements have been met, a grant of the benefit sought on appeal is warranted. 2. Entitlement to TDIU. Relevant law and regulations It is the established policy of VA that all veterans who are unable to secure and follow a substantially gainful occupation by reason of service-connected disabilities shall be rated totally disabled. See 38 C.F.R. § 4.16 (2008). A finding of total disability is appropriate "when there is present any impairment of mind or body which is sufficient to render it impossible for the average person to follow a substantially gainful occupation." See 38 C.F.R. §§ 3.340(a)(1), 4.15 (2008). "Substantially gainful employment" is that employment "which is ordinarily followed by the nondisabled to earn their livelihood with earnings common to the particular occupation in the community where the veteran resides." Moore v. Derwinski, 1 Vet. App. 356, 358 (1991). "Marginal employment shall not be considered substantially gainful employment." 38 C.F.R. § 4.16(a) (2008). The Court noted the following standard announced by the United States Court of Appeals for the Eighth Circuit in Timmerman v. Weinberger, 510 F.2d 439, 442 (8th Cir. 1975): It is clear that the claimant need not be a total 'basket case' before the courts find that there is an inability to engage in substantial gainful activity. The question must be looked at in a practical manner, and mere theoretical ability to engage in substantial gainful employment is not a sufficient basis to deny benefits. The test is whether a particular job is realistically within the physical and mental capabilities of the claimant. A claim for a total disability rating based upon individual unemployability "presupposes that the rating for the [service-connected] condition is less than 100%, and only asks for TDIU because of 'subjective' factors that the 'objective' rating does not consider." Vettese v. Brown, 7 Vet. App. 31, 34-35 (1994). In Hatlestad v. Derwinski, 1 Vet. App. 164 (1991), the Court referred to apparent conflicts in the regulations pertaining to individual unemployability benefits. Specifically, the Court indicated there was a need to discuss whether the standard delineated in the controlling regulations was an "objective" one based on the average industrial impairment or a "subjective" one based upon the Veteran's actual industrial impairment. In a pertinent precedent decision, the VA General Counsel concluded that the controlling VA regulations generally provide that veterans who, in light of their individual circumstances, but without regard to age, are unable to secure and follow a substantially gainful occupation as the result of service-connected disability shall be rated totally disabled, without regard to whether an average person would be rendered unemployable by the circumstances. Thus, the criteria include a subjective standard. It was also determined that "unemployability" is synonymous with inability to secure and follow a substantially gainful occupation. VAOPGCPREC 75-91. In determining whether unemployability exists, consideration may be given to the veteran's level of education, special training and previous work experience, but not to his age or to any impairment caused by non service-connected disabilities. 38 C.F.R. §§ 3.341, 4.16, 4.19 (2008). A total disability rating for compensation may be assigned, where the schedular rating is less than total, when the disabled person is, in the judgment of the rating agency, unable to secure or follow a substantially gainful occupation as a result of service-connected disabilities, provided that, if there is only one such disability, this disability shall be ratable at 60 percent or more. See 38 C.F.R. § 4.16(a) (2008). Pursuant to 38 C.F.R. § 4.16(b), when a claimant is unable to secure and follow a substantially gainful occupation by reason of service-connected disabilities, but fails to meet the percentage requirements for eligibility for a total rating set forth in 38 C.F.R. § 4.16(a), such case shall be submitted for extraschedular consideration in accordance with 38 C.F.R. § 3.321. Analysis As has been discussed in the law and regulations section above, TDIU may be awarded on either a schedular basis or an extraschedular basis. As explained below, in this case only the schedular basis need be considered. The Veteran is service-connected for cervical myositis with disc disease, status post C5-6 interbody fusion, which is currently 60 percent disabling. As described above service connection has been awarded for depression; although a disability rating has yet to be assigned, in light of the 60 percent rating currently assigned to the cervical spine disability the Veteran meets the criteria for schedular consideration of TDIU. See 38 C.F.R. § 4.16(a) (2006). For reasons stated immediately below, the Board finds that the evidence of record demonstrates that the Veteran's service-connected disabilities render him unable to secure and follow a substantially gainful occupation. The Veteran has testified that he is incapable of any sort of physical labor due to his service-connected cervical spine disability since having surgery in 1997. See the December 2005 hearing transcript, page 24. As described above, the Veteran also has chronic depression attributable to his service-connected cervical spine disability, which causes "significant problems with mood, affect, sleep, energy, focus, concentration, drive and emotional liability." See the October 2002 statement of Dr. E.C.L. In support of his contentions, the Veteran has submitted a number of statements from his treating physicians pertaining to the effect of his service-connected cervical spine disability and depression on his employability. Dr. E.C.L. has indicated the Veteran's "psychiatric symptoms and the extent and constancy of their presentation make [the Veteran] unemployable." The October 1999 VA examiner similarly concluded the Veteran "has difficulty dealing with stress. His psychiatric condition has persisted over the last couple of years despite optimal treatment. The Veteran is not able to tolerate the stresses of the work place." D.R.B., Ph.D., concluded in January 1999 that the Veteran "is unable to be gainfully employed [and] increasingly unable to live in any functionally effective way outside his home" due to his psychiatric symptoms. C.N.B., M.D., also provided testimony that the Veteran's cervical spine disability prevents him from working, noting: "his function is bad, and over the years multiple of the doctors say he's unemployable. He has additional problems now. He has worsening of symptoms. He has increasing pain, and he also has some bladder problems that may be due to his neck. So with that constellation of things, I think he's unemployable." See the December 2005 hearing transcript, page 23. Dr. C.N.B. also submitted a statement dated in May 2004 indicating the Veteran "has been unable to obtain or maintain gainful employment due to his service-connected spine problems since the date of his surgery in July 1997." The October 1999 VA spine examiner similarly concluded that the Veteran's cervical spine symptoms "prevents [sic] him from getting any gainful employment until he gets the surgery done and pressure removed from the nerve roots in the neck." M.P.D., D.C., stated in January 1998 that "it is my opinion at this time due to his physical limitations [stemming from chronic injury and cervical spine fusion] and depression he is not suitable for employment. This conclusion is consistent with the objective evidence of record, to include numerous private outpatient records which demonstrate the Veteran's continuous complaints of severe neck pain, spasm and exacerbating episodes as well as chronic depression. In short, the medical and other evidence of record indicates that the Veteran's service-connected cervical spine disability and depression are productive of serious symptomatology which can be said to preclude employability. Based on the above analysis, the Board concludes that a grant of TDIU is warranted under 38 C.F.R. § 4.16(a). In conclusion, for the reasons and bases expressed above the Board finds that the Veteran's claim for TDIU is warranted on a schedular basis. The benefit sought on appeal is accordingly granted. 3. Entitlement to an effective date earlier than December 1, 1997 for the assignment of a 60 percent disability rating for service-connected cervical myositis with disc disease, status post C5-6 interbody fusion. Relevant law and regulations Effective dates - increased rating claims The effective date of an award of increased disability compensation shall be the earliest date as of which it is factually ascertainable that an increase in disability had occurred, if application is received within one year from such date; otherwise, the effective date will be the date of VA receipt of the claim for increase, or the date entitlement arose, whichever is later. 38 U.S.C.A. § 5110(a),(b)(2) (West 2002); 38 C.F.R. § 3.400(o) (2008); Hazan v. Gober, 10 Vet. App. 511 (1997); Harper v. Brown, 10 Vet. App. 125 (1997). The Court has held that 38 U.S.C.A. § 5110(b)(2) and 38 C.F.R. § 3.400(o)(2) are applicable only where an increase in disability precedes a claim for an increased disability rating; otherwise the general rule of 38 C.F.R. § 3.400(o)(1) applies. See Harper, supra. Thus, three possible dates may be assigned depending on the facts of the case: (1) if an increase in disability occurs after the claim is filed, the date that the increase is shown to have occurred (date entitlement arose) (38 C.F.R. § 3.400(o)(1)); (2) if an increase in disability precedes the claim by a year or less, the date that the increase is shown to have occurred (factually ascertainable) (38 C.F.R. § 3.400(o)(2)); (3) if an increase in disability precedes the claim by more than a year, the date that the claim is received (date of claim) (38 C.F.R. § 3.400(o)(2)). See Harper, 10 Vet. App at 126. Claims for VA benefits A specific claim in the form prescribed by the Secretary must be filed in order for benefits to be paid or furnished to any individual under the laws administered by VA. 38 U.S.C.A. § 5101(a) (West 2002); 38 C.F.R. § 3.151(a) (2008). A claim is a formal or informal communication in writing requesting a determination of entitlement or evidencing a belief in entitlement to a benefit. 38 U.S.C.A. § 101(30) (West 2002); 38 C.F.R. § 3.1(p) (2008). The date of receipt shall be the date on which a claim, information or evidence was received at VA. 38 U.S.C.A. § 101(30) (West 2002); 38 C.F.R. § 3.1(r) (2008). Any communication or action indicating an intent to apply for one or more benefits under the laws administered by VA, from a Veteran or his representative, may be considered an informal claim. Such informal claim must identify the benefit sought. Upon receipt of an informal claim, if a formal claim has not been filed, an application form will be forwarded to the claimant for execution. If received within one year from the date it was sent to the Veteran, it will be considered filed as of the date of receipt of the informal claim. When a claim has been filed which meets the requirements of 38 C.F.R. §§ 3.151 or 3.152, an informal request for increase or reopening will be accepted as a claim. 38 C.F.R. § 3.155 (2008). Diagnostic criteria The applicable rating criteria for the spine, found at 38 C.F.R. § 4.71a, were amended effective September 23, 2002 and September 26, 2003. However, VA's Office of General Counsel has determined that the amended rating criteria can be applied only for the period from and after the effective date of the regulatory change. See VAOPGCPREC 3-2000. Therefore, only the former criteria are applicable to this issue, which involves the period before December 1, 1997. Diagnostic Code 5293, effective prior to September 23, 2002, provided a 60 percent rating for pronounced intervertebral disc syndrome, with persistent symptoms compatible with sciatic neuropathy with characteristic pain and demonstrable muscle spasm, absent ankle jerk, or other neurological findings appropriate to the site of the diseased disc, and little intermittent relief. A 40 percent rating was warranted for severe intervertebral disc syndrome, with recurrent attacks with intermittent relief; a 20 percent rating was warranted for moderate intervertebral disc syndrome with recurrent attacks, and a 10 percent rating was warranted for mild intervertebral disc syndrome. See 38 C.F.R. § 4.71a, Diagnostic Code 5293 (prior to September 23, 2002). Factual background The Board believes that an exposition of the factual background will aid in an understanding of its decision. The record reflects that in a September 1982 rating decision, service connection was granted for a cervical spine disability and a noncompensable (zero percent) disability rating was assigned. A June 1989 rating decision awarded a 10 percent rating for the service-connected cervical spine disability. The Veteran did not appeal that decision. In a statement received at the RO on August 10, 1992, the Veteran requested an examination to determine the current severity of his service-connected cervical spine disability. This was correctly interpreted by the RO as a claim for an increased rating. In a January 1993 rating decision, the RO assigned a 20 percent disability rating for the service- connected cervical spine disability, effective August 6, 1992. The Veteran perfected an appeal of that decision. A rating decision dated in June 1999 assigned a 40 percent rating effective September 27, 1995. The Board awarded a 60 percent disability rating for the service-connected cervical spine disability in a May 2006 decision. An October 2006 rating decision implemented the Board's findings, assigning a 60 percent rating, effective December 1, 1997. [A temporary total evaluation was also assigned from July 11, 1997 to December 1, 1997. See 38 C.F.R. § 4.30 (2008).] The Veteran indicated his disagreement with the December 1, 1997 effective date assigned for the 60 percent rating effective December 1, 1997. Accordingly, the ratings for the service-connected cervical spine disability under former Diagnostic Code 5293 are staged as follows: 20 percent from August 6, 1992; 40 percent from September 27, 1995; 100 percent from July 11, 1997 to November 30, 1997; 60 percent from December 1, 1997. Analysis The RO has assigned an effective date of December 1, 1997 for the 60 percent rating for the cervical spine disability. The Veteran seeks entitlement to an earlier effective date. The Veteran, through his attorney, offers two arguments as to the early effective date claim on appeal: (1) that the effective date of the 60 percent rating should be from the date of his increased rating claim on August 1992 or in the year prior per 38 C.F.R. § 3.400(o); and (2) the date of the 60 percent rating should be July 11, 1997, the date the Veteran underwent a cervical discectomy. See the November 10, 2006 notice of disagreement. With respect to the attorney's second argument, as noted above the Veteran has been provided a temporary total evaluation from July 11, 1997 to November 30, 1997 as a result of his cervical discectomy. Accordingly, extending the effective date for the 60 percent rating back to the date of surgery on July 11, 1997 would be of no benefit to the Veteran, and indeed would not be in his interest, as he is already in receipt of a 100 percent rating for that period of time. Accordingly, the period of the previously assigned temporary total rating, from July 11, 1997 to November 30, 1997, is not for consideration in adjudicating the earlier effective date claim. As was described in the law and regulations section above, determining an appropriate effective date for an increased rating involves an analysis of the evidence to determine (1) when the claim for an increased rating was received and (2) when entitlement arose (i.e., when the increase in disability actually occurred). See 38 C.F.R. §§ 3.155, 3.400(o)(2). (i.) Date of claim As has been discussed in the factual background section above, the Veteran's previous increased rating claims were adjudicated by the RO, the last such final adjudication being an unappealed June 1989 rating decision. See 38 U.S.C.A. § 7105 (West 2002). A review of the record reveals that there is no communication from the Veteran or a representative of the Veteran to VA which can be interpreted as a claim for an increased rating for the cervical spine disability after the June 23, 1989 notice of the June 1989 rating decision and prior to the August 10, 1992 claim for an increased rating. See Servello v. Derwinski, 3 Vet. App. 196, 198-200 (1992) [the Board must look at all communications that can be interpreted as a claim, formal or informal, for VA benefits]. Neither the Veteran or his counsel has identified such a claim. Additionally, there are no reports of VA outpatient treatment dated in the year prior to August 10, 1992 which could be construed as an informal claim under 38 C.F.R. § 3.157. [The Board notes there is a record from M.P.D., D.C., dated August 6, 1992 and three treatment records from J.D.C., D.O. However, these are private records, and the provisions of 38 C.F.R. § 3.157 only apply to reports of VA treatment.] Accordingly, the date of the increased rating claim is August 10, 1992. (ii.) Date entitlement arose The Board's inquiry now shifts to the date entitlement to an increased rating arose, that is when it was factually ascertainable that an increase in disability occurred. The time frame in question starts a year before the August 10, 1992 claim, i.e., on August 10, 1991. The evidence shows that disability consistent with the assignment of a 40 percent rating under Diagnostic Code 5293 was first medically identified on December 30, 1996. At this time the Veteran first reported periods of flare-up with a complete loss of function requiring bed rest with hot packs, which was substantiated by the VA examiner. The examiner further noted an "increased amount of stiffness and pain in the neck," and though muscle spasm was not objectively demonstrated the examiner acknowledged severe muscle spasms occur "from time to time." Moreover, a considerable drop in the right shoulder and loss in the normal cervical lordotic curvature was noted at this time. Such findings are consistent with severe intervertebral disc syndrome. Before December 30, 1996, symptoms consistent with a 20 percent rating were present. Although M.P.D. vaguely indicated the Veteran experienced "recurrent severe exacerbative episodes" in an August 1992 statement, the relevant objective evidence from the period in question does not support his statement. The Veteran reported no such attacks when he was seen in March 1992 and described only "periodic" muscle spasms when examined in September 1992. Moreover, aside from the diagnostic testing conducted in February 1992, the Veteran sought no treatment for his cervical spine prior to M.P.D.'s statement. See Forshey v. West, 12 Vet. App. 71, 74 (1998), aff'd sub nom. Forshey v. Principi, 284 F.3d 1335, 1358 (Fed. Cir. 2002) [the definition of evidence encompasses "negative evidence" which tends to disprove the existence of an alleged fact, i.e., the lack of evidence is itself evidence]. Furthermore, the evidence from this period reflects that deep tendon reflexes were normal and equal bilaterally and sensation was intact. Though as described above the Veteran reported occasional muscle spasm, none was identified upon objective examination. An EMG study reviewed in May 1995 was completely normal, and the September 1995 VA examiner found no evidence of cervical radiculopathy or myelopathy. Additionally, the Veteran noted "dramatic improvement" with physical therapy from April 1994 to October 1994, with an October 1994 physical therapy note indicating full range of motion, strength and work capacity of the cervical spine. Additionally, the Veteran was capable of engaging in an exercise program during this time, with T.W.B. noting "well- defined musculature secondary to exercise" in April 1995 and the September 1995 VA examiner describing the Veteran as "very muscular." Such findings are indicative of no more than moderate intervertebral disc syndrome. Thus, the competent medial evidence of record indicates that an increase in disability to the 40 percent level was initially identified on December 30, 1996. However, as noted above the RO has assigned a 40 percent rating from the VA examination conducted on September 27, 1995, a finding which the Board will not disturb. The Board will therefore move on to a discussion of when an increase to the 60 percent level was first identified. The evidence shows that disability consistent with the assignment of a 60 percent rating under Diagnostic Code 5293 has not been medically identified prior the current effective date of December 1, 1997. Specifically, characteristic pain was demonstrated in the December 1996 VA examination report and in a June 1997 physical therapy note. However, pursuant to former Diagnostic Code 5293 such must be accompanied by "demonstrable muscle spasm," which was not objectively demonstrated at those times. See Melson v. Derwinski, 1 Vet. App. 334 (1991) [use of the conjunctive "and" in a statutory provision meant that all of the conditions listed in the provision must be met]. Absent ankle jerk or other neurological findings appropriate to the site of the diseased disc are similarly not demonstrated in the evidence dated prior to December 1, 1997. Although the June 1997 physical therapy note referenced "radiculitis," such findings are in direct contrast to objective neurological testing conducted during the period in question, namely the February 1997 MRI report and the September 1995 VA examiner's report indicating "no evidence of cervical radiculopathy or myelopathy." Additionally, deep tendon reflexes and sensory testing were normal throughout the period in question, and no foot drop or bladder or bowel dysfunction was identified. Finally, the December 1996 VA examiner's description of periods of flare- ups "from time to time" is indicative of periods of intermittent relief. Such findings correspond precisely to a 40 percent rating and do not equate with "pronounced intervertebral disc syndrome" allowing for assignment of a 60 percent rating under Diagnostic Code 5293. Therefore, the RO's choice of an effective date for the 60 percent rating was correct. With respect to the argument of counsel, to the effect that the Veteran has had pronounced intervertebral disc syndrome since he filed his increased rating claim, the Board's decision has been based on the entirety of the medical evidence, which has been summarized above. It is well- settled that lay persons without medical training, such as the Veteran's attorney, are not competent to comment on medical matters. See Espiritu v. Derwinski, 2 Vet. App. 492, 494-5 (1992); see also 38 C.F.R. § 3.159 (a)(1) [competent medical evidence means evidence provided by a person who is qualified through education, training, or experience to offer medical diagnoses, statements, or opinions]. In conclusion, for reasons stated above, the Board finds that that an effective date earlier than December 1, 1997 may not be granted for the 60 percent rating for the cervical spine disability. ORDER Service connection for depression is granted. Entitlement to TDIU is granted, subject to controlling regulations applicable to the payment of monetary benefits. Entitlement to an effective date prior to December 1, 1997 for the assignment of a 60 percent disability rating for service-connected cervical myositis with disc disease, status post C5-6 interbody fusion is denied. ____________________________________________ Barry F.
