Citation Nr: 1329660 Decision Date: 09/16/13 Archive Date: 09/20/13 DOCKET NO. 09-08 133 ) DATE ) ) On appeal from the Department of Veterans Affairs Regional Office in Atlanta, Georgia THE ISSUE Entitlement to an increased evaluation for low back pain, currently rated 10 percent disabling. REPRESENTATION Appellant represented by: Georgia Department of Veterans Services WITNESS AT HEARING ON APPEAL The Veteran ATTORNEY FOR THE BOARD Bernard T. DoMinh, Counsel INTRODUCTION The Veteran served on active duty from July 1985 to October 1988. This matter comes to the Board of Veterans' Appeals (Board) on appeal from a February 2007 rating decision by the Atlanta, Georgia, Regional Office (RO) of the Department of Veterans Affairs (VA) which, inter alia, denied the Veteran's claim for a rating greater than 10 percent for her service-connected low back pain. In September 2012, the Veteran, accompanied by her representative, appeared at the RO to present oral testimony and submit evidence and arguments in support of her appeal before the undersigned Veterans Law Judge. A transcript of this hearing has been obtained and associated with the Veteran's claims file for the Board's review and consideration. In April 2013, the Board remanded the case to the RO via the Appeals Management Center (AMC) in Washington, D.C., for additional evidentiary development, including scheduling the Veteran for an examination to assess the severity of her service-connected low back pain. After this development, the case was readjudicated by the AMC in a May 2013 supplemental statement of the case, which confirmed and continued the 10 percent evaluation assigned for low back pain. The case was recertified to the Board in June 2013 and returned to the Board's custody in July 2013, and the Veteran now continues her appeal. (The Board notes that an additional issue of entitlement to service connection for mitral valve prolapse was also on appeal and was remanded by the Board in April 2013 for additional evidentiary development, which included scheduling the Veteran for a VA medical examination in April 2013. Based on a favorable nexus opinion presented by the examining clinician, the Veteran was granted service connection and a 10 percent rating for mitral valve prolapse in a May 2013 rating decision, thereby fully granting the benefit sought on appeal in this regard and ending the Veteran's appeal with respect only this specific issue.) FINDING OF FACT During the pendency of the claim, the Veteran's service- connected low back pain has been manifested by subjective complaints of chronic, persistent low back pain with radiculopathic symptoms radiating down her right lower extremity and foot, with the confirmed presence of degenerative changes of her lumbosacral spine, vertebrae, discs on medical imaging studies, and limitation of thoracolumbar forward flexion to greater than 60 degrees but not greater than 85 degrees, with a combined range of thoracolumbar motion of greater than 120 degrees but not greater than 235 degrees on repetitive motion testing (factoring in functional loss due to pain), with muscle spasm that does not alter her gait and no neurological impairment of the adjacent peripheral nerves or incapacitating episodes associated with the radiculopathic component of her low back disability. CONCLUSION OF LAW The criteria for the assignment of an evaluation greater than 10 percent for service-connected low back pain have not been met. 38 U.S.C.A. § 1155 (West 2002); 38 C.F.R. § 4.71a, Diagnostic Code 5237 (2012). REASONS AND BASES FOR FINDING AND CONCLUSION The Veterans Claims Assistance Act of 2000 (VCAA) With respect to the claim decided herein, the Board notes at the outset that, in accordance with the VCAA, VA has an obligation to notify claimants what information or evidence is needed in order to substantiate a claim, as well as a duty to assist claimants by making reasonable efforts to get the evidence needed. 38 U.S.C.A. §§ 5100, 5102, 5103, 5103A and 5107 (West 2002); 38 C.F.R. §§ 3.102, 3.156(a), 3.159, 3.326(a) (2012); see also Quartuccio v. Principi, 16 Vet. App. 183, 187 (2002). Generally, the notice requirements of a claim have five elements: veteran status, existence of a disability, a connection between the veteran's service and the disability, degree of disability, and effective date of the disability. Dingess v. Nicholson, 19 Vet. App. 473 (2006). VCAA notice must also: (1) inform the claimant about the information and evidence necessary to substantiate the claim; (2) inform the claimant about the information and evidence that VA will seek to provide; (3) inform the claimant about the information and evidence the claimant is expected to provide; and (4) request that the claimant provide any evidence in his possession that pertains to the claim. See 38 U.S.C. § 5103(a); 38 C.F.R. § 3.159(b); Beverly v. Nicholson, 19 Vet. App. 394, 403 (2005) (outlining VCAA notice requirements). 38 C.F.R. § 3.159(b) has since been revised and the requirement that VA request that the claimant provide any evidence in his possession that pertains to the claim was removed from the regulation. The current claim was filed on June 22, 2006. A VCAA notice letter was dispatched to the Veteran in July 2006, prior to the February 2007 rating decision now on appeal. This letter addressed the issue on appeal and satisfied the above-described mandates, as well as the requirements that the Veteran be informed of how VA calculates degree of disability and assigns an effective date for the disability, as prescribed in Dingess v. Nicholson, 19 Vet. App. 473 (2006). As fully compliant notice preceded the initial adjudication of the Veteran's claims adjudicated herein, there is no timing of notice defect. VA also has a duty to assist the Veteran in obtaining evidence necessary to substantiate a claim. 38 U.S.C.A. § 5103A(a) ("The Secretary shall make reasonable efforts to assist a claimant in obtaining evidence necessary to substantiate the . . . claim"). This duty includes assisting the Veteran in obtaining records and providing medical examinations or obtaining medical opinions when such are necessary to make a decision on the claim. 38 U.S.C.A. § 5103A(b), (c), (d) (setting forth Secretary's various duties to claimant). VA informed the Veteran of its duty to assist in obtaining records and supportive evidence with regard to the increased rating claim adjudicated herein. As the claim stems from June 22, 2006, when the Veteran filed her claim for an increased rating for the service-connected low back pain at issue, the relevant time period and evidence that must be addressed in the adjudication of the claim encompasses the period from June 22, 2005 to the present, in order to allow the Board to consider the applicability of a staged rating. See 38 C.F.R. § 3.400(o)(2) (2012); Hart v. Mansfield, 21 Vet. App. 505 (2007). In this regard, the Board observes that private and VA clinical records for the period spanning 2005 to 2013, including reports of VA medical examinations of the disabilities at issue, dated in July 2006, January 2009 and April 2013, have been obtained and associated with the claims file, or are otherwise viewable on the Virtual VA electronic information database. The Board has reviewed the aforementioned examination reports and notes that the Veteran's claims file was reviewed by the VA clinicians who performed them, and that these examiners provided adequate discussion of their clinical observations and rationales to support their individual findings and conclusions within the context of the Veteran's pertinent clinical history as contained within her claims file. The examinations are therefore deemed adequate for rating purposes. Barr v. Nicholson, 21 Vet. App. 303, 311-12 (2007); Stefl v. Nicholson, 21 Vet. App. 120, 124 (2007). At this juncture, the Board notes that, in correspondence dated in April 2013 and June 2013, the Veteran challenges the validity of the April 2013 VA examination's findings, claiming that she was wheelchair-bound at the time of this examination due to a flare-up of low back pain and was unable to perform range-of-motion tests, and that the examiner who conducted the examination had re-used old range-of-motion test findings from the prior VA examination of 2009 and had furthermore displayed a decided bias against the Veteran's claim. After reviewing the April 2013 VA examination report and the contemporaneous evidence of record, the Board is unable to find any such discrepancies, irregularities, or evidence of personal bias as alleged by the Veteran. Specifically, neither the April 2013 VA orthopedic examination report nor the report of a concurrently performed VA cardiac examination indicates that the Veteran was wheelchair-bound or was otherwise using a wheelchair in any capacity during these examinations. In fact, the examination report includes a box for the examiner to specifically check if the examination subject is using a wheelchair and the box is not checked to affirm the presence of this assistive ambulatory device. Also, the objective range-of-motion findings obtained on examination in April 2013 do not exactly match the results of the range-of-motion study performed during VA examination in January 2009, such that the Veteran's allegation that old clinical findings were re-used in lieu of conducting actual testing is not substantiated. Specifically, thoracolumbar range of motion testing in January 2009 revealed forward flexion to 87 degrees, backward extension to 27 degrees, lateral flexion to 30 degrees (bilaterally), and lateral rotation to 30 degrees (bilaterally), limited by onset of pain following repetitive motion testing, as compared to dissimilar findings on thoracolumbar range of motion testing in April 2013, which revealed forward flexion to 70 degrees, backward extension to 20 degrees, lateral flexion to 20 degrees (bilaterally), and lateral rotation to 30 degrees (bilaterally), limited by onset of pain following repetitive motion testing. Finally, the clinical record does not indicate the presence of a personal bias against the Veteran or the merits of her claim as the VA clinician who conducted the April 2013 orthopedic examination also performed the concurrent April 2013 cardiac examination, in which the clinician provided a favorable nexus opinion that ultimately resulted in the Veteran being awarded service connection and a 10 percent evaluation for mitral valve prolapse. See May 2013 rating decision. Thus, the Board concludes as a factual matter that, notwithstanding the Veteran's allegations of inaccuracy and bias, the April 2013 VA orthopedic examination was properly conducted, and its objective clinical findings are adequate for VA rating purposes. A remand for corrective action is thus not warranted. The Veteran was provided with the opportunity to present oral testimony in support of her claim before the undersigned Veterans Law Judge in a September 2012 hearing. At the time of the hearing, the Veteran was accompanied by her representative and had the benefit of his advice and counsel. In Bryant v. Shinseki, 23 Vet. App. 488 (2010), the United States Court of Appeals for Veterans Claims (Court) held that 38 C.F.R. § 3.103(c)(2) (2012) requires that the Decision Review Officer or Veterans Law Judge who chairs a hearing fulfill two duties to comply with the above regulation. These duties consist of (1) explaining fully the issues and (2) discussing the submission of evidence that may have been overlooked. Bryant v. Shinseki, 23 Vet. App. 488 (2010). At the September 2012 hearing, the presiding Veterans Law Judge's questions and the Veteran's oral testimony focused on the elements necessary to substantiate, inter alia, the Veteran's claim for an increased rating for her low back disability. See transcript of September 13, 2012 hearing. Thus, the Board finds that the Veterans Law Judge presiding over the September 2012 hearing has substantially fulfilled her obligations as required under 38 C.F.R. § 3.103(c)(2). Bryant, supra. Based on the foregoing, the Board finds that the VA fulfilled its VCAA duties to notify and to assist the Veteran in the evidentiary development of the claim decided herein, and thus no additional assistance or notification is required. The Veteran has suffered no prejudice that would warrant a remand, and her procedural rights have not been abridged. See Bernard v. Brown, 4 Vet. App. 384 (1993). The Board will therefore proceed with the adjudication of this appeal. Increased ratings - generally The Board has thoroughly reviewed all the evidence in the Veteran's claims file. Although the Board has an obligation to provide reasons and bases supporting this decision, there is no need to discuss, in detail, the evidence submitted by the appellant or on her behalf. See Gonzales v. West, 218 F.3d 1378, 1380-81 (Fed. Cir. 2000) (the Board must review the entire record, but does not have to discuss each piece of evidence). The analysis below focuses on the most salient and relevant evidence and on what this evidence shows, or fails to show, on the claim. The appellant must not assume that the Board has overlooked pieces of evidence that are not explicitly discussed herein. See Timberlake v. Gober, 14 Vet. App. 122 (2000) (the law requires only that the Board address its reasons for rejecting evidence favorable to the claimant). The Board must assess the credibility and weight of all evidence, including the medical evidence, to determine its probative value, accounting for evidence which it finds to be persuasive or unpersuasive, and providing reasons for rejecting any evidence favorable to the claimant. Equal weight is not accorded to each piece of evidence contained in the record; every item of evidence does not have the same probative value. When all the evidence is assembled, VA is responsible for determining whether the evidence supports the claim or is in relative equipoise, with the appellant prevailing in either event, or whether a preponderance of the evidence is against a claim, in which case, the claim is denied. See Gilbert v. Derwinski, 1 Vet. App. 49 (1990). Disability ratings are determined by applying the criteria set forth in the VA's Schedule for Rating Disabilities, which is based on the average impairment of earning capacity. Individual disabilities are assigned separate diagnostic codes. 38 U.S.C.A. § 1155; 38 C.F.R. § 4.1 (2012). The basis of disability evaluations is the ability of the body as a whole, or of the psyche, or of a system or organ of the body to function under the ordinary conditions of daily life including employment. 38 C.F.R. § 4.10 (2012). In determining the severity of a disability, the Board is required to consider the potential application of various other provisions of the regulations governing VA benefits, whether or not they were raised by the Veteran, as well as the entire history of the Veteran's disability. 38 C.F.R. §§ 4.1, 4.2 (2012); Schafrath v. Derwinski, 1 Vet. App. 589, 595 (1991). If the disability more closely approximates the criteria for the higher of two ratings, the higher rating will be assigned; otherwise, the lower rating is assigned. 38 C.F.R. § 4.7 (2012). It is not expected that all cases will show all the findings specified; however, findings sufficiently characteristic to identify the disease and the disability therefrom and coordination of rating with impairment of function will be expected in all instances. 38 C.F.R. § 4.21 (2012). In deciding this appeal, the Board has considered whether separate ratings for different periods of time, based on the facts found, are warranted, a practice of assigning ratings referred to as "staging the ratings." See Fenderson v. West, 12 Vet. App. 119 (1999); Hart v. Mansfield, 21 Vet. App. 505 (2008). Based on the June 22, 2006 date of VA's receipt of the Veteran's application to reopen her claim for a rating increase, the relevant temporal focus for the increased rating claim for a chronic low back disability is from June 22, 2005. See 38 C.F.R. § 3.400 (2012). Entitlement to an increased evaluation for low back pain, currently rated 10 percent disabling. The Veteran is service-connected for chronic low back pain, which her service treatment records indicate is the result of a traumatic straining injury incurred during active duty. The criteria for rating all spine disabilities are set forth in a General Rating Formula for Diseases and Injuries of the Spine provide that these disabilities are to be evaluated either under the General Rating Formula for Diseases and Injuries of the Spine or under the Formula for Rating Intervertebral Disc Syndrome Based on Incapacitating Episodes, whichever method results in the higher rating when all disabilities are combined under 38 C.F.R. § 4.25. Disability of the musculoskeletal system is primarily the inability, due to damage or infection in the parts of the system, to perform the normal working movements of the body with normal excursion, strength, speed, coordination, and endurance. It is essential that the examination on which ratings are based adequately portray the anatomical damage and the functional loss with respect to all of these elements. In evaluating disabilities of the musculoskeletal system, it is necessary to consider, along with the schedular criteria, functional loss due to flare-ups of pain, fatigability, incoordination, pain on movement, and weakness. DeLuca v. Brown, 8 Vet. App. 202 (1995). The functional loss may be due to absence of part, or all, of the necessary bones, joints and muscles, or associated innervations, or other pathology and evidenced by visible behavior of the claimant undertaking the motion. Weakness is as important as limitation of motion, and a part that becomes painful on use must be regarded as seriously disabled. 38 C.F.R. § 4.40 . Pain on movement, swelling, deformity or atrophy of disuse as well as instability of station, disturbance of locomotion, interference with sitting, standing and weight bearing are relevant considerations for determination of joint disabilities. 38 C.F.R. § 4.45 . Painful, unstable, or misaligned joints due to a healed injury are entitled to at least the minimal compensable rating for the joint. 38 C.F.R. § 4.59 . The pertinent part of the General Formula for rating disability of the thoracolumbar (to include the lumbosacral) spine is as follows: With or without symptoms such as pain (whether or not it radiates), stiffness, or aching in the area of the spine affected by residuals of injury or disease Unfavorable ankylosis of the entire spine, assign a 100 percent rating. Unfavorable ankylosis of the entire thoracolumbar spine, assign a 50 percent rating. Forward flexion of the thoracolumbar spine 30 degrees or less; or, favorable ankylosis of the entire thoracolumbar spine, assign a 40 percent rating. Forward flexion of the thoracolumbar spine greater than 30 degrees but not greater than 60 degrees; or, the combined range of motion of the thoracolumbar spine not greater than 120 degrees; or, muscle spasm or guarding severe enough to result in an abnormal gait or abnormal spine contour such as scoliosis, reversed lordosis, or abnormal kyphosis, assign a 20 percent rating. Forward flexion of the thoracolumbar spine greater than 60 degrees but not greater than 85 degrees; or, combined range of motion of the thoracolumbar spine greater than 120 degrees but not greater than 235 degrees; or, muscle spasm, guarding, or localized tenderness not resulting in abnormal gait or abnormal spinal contour; or, vertebral body fracture with loss of 50 percent or more of height, assign a 10 percent rating. Note (1): Evaluate any associated objective neurologic abnormalities. . . separately, under an appropriate diagnostic code. Note (2): (See also Plate V.) For VA compensation purposes, normal forward flexion of the thoracolumbar spine is zero to 90 degrees, extension is zero to 30 degrees, left and right lateral flexion are zero to 30 degrees, and left and right lateral rotation are zero to 30 degrees. The combined range of motion refers to the sum of the range of forward flexion, extension, left and right lateral flexion, and left and right rotation. The normal combined range of motion of the thoracolumbar spine is 240 degrees. The normal ranges of motion for spinal motion provided in this note are the maximum that can be used for calculation of the combined range of motion. Note (3): In exceptional cases, an examiner may state that because of age, body habitus, neurologic disease, or other factors not the result of disease or injury of the spine, the range of motion of the spine in a particular individual should be considered normal for that individual, even though it does not conform to the normal range of motion stated in Note (2). Provided that the examiner supplies an explanation, the examiner's assessment that the range of motion is normal for that individual will be accepted. Note (4): Round each range of motion measurement to the nearest five degrees. Note (5): For VA compensation purposes, unfavorable ankylosis is a condition in which the entire thoracolumbar spine, or the entire spine. . . is fixed in flexion or extension, and the ankylosis results in one or more of the following: difficulty walking because of a limited line of vision; restricted opening of the mouth and chewing; breathing limited to diaphragmatic respiration; gastrointestinal symptoms due to pressure of the costal margin on the abdomen; dyspnea or dysphagia; atlantoaxial or cervical subluxation or dislocation; or neurologic symptoms due to nerve root stretching. Fixation of a spinal segment in neutral position (zero degrees) always represents favorable ankylosis. Note (6): Separately evaluate disability of the thoracolumbar and cervical spine segments, except when there is unfavorable ankylosis of both segments, which will be rated as a single disability. Formula for Rating Intervertebral Disc Syndrome (IVDS) Based on Incapacitating Episodes provides as follows: With incapacitating episodes having a total duration of at least 6 weeks during the past 12 months, assignment of a 60 percent evaluation is warranted. With incapacitating episodes having a total duration of at least 4 weeks but less than 6 weeks during the past 12 months, assignment of a 40 percent evaluation is warranted. With incapacitating episodes having a total duration of at least 2 weeks but less than 4 weeks during the past 12 months, assignment of a 20 percent evaluation is warranted. With incapacitating episodes having a total duration of at least one week but less than 2 weeks during the past 12 months, assignment of a 10 percent evaluation is warranted. Note (1): For purposes of evaluations under diagnostic code 5243 [intervertebral disc syndrome], an incapacitating episode is a period of acute signs and symptoms due to intervertebral disc syndrome that requires bed rest prescribed by a physician and treatment by a physician. Note (2): If intervertebral disc syndrome is present in more than one spinal segment, provided that the effects in each spinal segment are clearly distinct, evaluate each segment on the basis of incapacitating episodes or under the General Rating Formula for Diseases and Injuries of the Spine, whichever method results in a higher evaluation for that segment. 38 C.F.R. § 4.71a, Diagnostic Code 5243 (2012). The Veteran testified at the September 2012 hearing that her current low back problems included pain (at level 7 on most days and up to 10 on the pain scale) radiating down her right leg; numbness and loss of feeling in her legs; difficulty going up and down stairs; loss of balance; an abnormal gait requiring the use of a cane most of the time; difficulty with prolonged sitting standing and with lifting; "incapacitating episodes" at least once a month (although she noted that her doctor did not prescribe bed rest, but had told her that when she had these flare ups she should rest in bed); and difficulty performing activities of daily living. She noted that these problems require her to take up to 20 pills a day just to deal with the pain and just to function. The entirety of the clinical evidence objectively demonstrates that, for the period from June 2005 to the present, the Veteran's service-connected low back disability (clinically diagnosed as degenerative joint disease of the lumbar spine with radiculopathy) is manifested by constant pain (subjectively described as being at least "5" on a scale of 1 to 10, with 10 being the worst pain), pain on use, and pain on motion, which necessitates treatment with prescribed oral non-narcotic and anti-inflammatory medications and occasional epidural steroid injections to partially relieve the symptoms. The Veteran was prescribed a TENS unit that the records indicate she seldom uses. She also occasionally ambulates with a cane during episodes of elevated symptomatology, but regular use of a cane was not indicated in the medical records. Her gait was sometimes slow and deliberate, but was not altered as a result of her low back pain. She reported radiating pain and radiculopathic symptoms down her right lower extremity and foot. Medical imaging pertinent to the period reveals degenerative joint and disc pathology at the site of her lumbosacral spine, with mild disc bulging but no evidence of vertebral fracture. A congenital hemivertebra anomaly at T12-L1 was noted as early as service, but current medical records indicate that this condition did not contribute to, or was otherwise aggravated by his service-connected low back disability. Range of motion testing of the Veteran's thoracolumbar spine on examination in July 2006, January 2009 and April 2013 collectively revealed limitation of thoracolumbar forward flexion to greater than 60 degrees but not greater than 85 degrees, and a combined range of thoracolumbar motion of greater than 120 degrees but not greater than 235 degrees on repetitive motion testing (and factoring in functional loss due to pain). Although at the July 2006 examination, the examiner noted that the Veteran was unable to perform repetitive motion testing, this notation does not appear to be an actual clinical finding of functional loss when considered with the entirety of the medical evidence, which clearly demonstrates on subsequent examinations in January 2009 and April 2013 that the Veteran was capable of performing repetitive movement of her thoracolumbar spine, with the functional loss due to pain and pain on motion as noted. Functional loss of the thoracolumbar spine was clinically attributed to pain on movement. The limiting factor in all range of motion studies was onset of back pain at the point of maximum forward flexion, backward extension, lateral flexion, and lateral rotation, confirmed by repetitive motion testing. No additional functional loss due to pain on movement or additional limitation of motion was demonstrated beyond that which was clinically noted. Muscle spasm was occasionally noted, but this was not shown to impair her gait. Otherwise, her lower extremity musculature displayed 5/5 strength with no atrophy, bilaterally. Although radiculopathy affecting her low back and right lower extremity was present, she was objectively determined to be 2+ and neurologically intact on neurosensory examination of her thoracolumbar spine and lower extremities and no actual incapacitating episodes of IVDS were clinically demonstrated during the entire pendency of the claim. Furthermore, the medical examinations pertinent to the pendency of this claim do not objectively demonstrate the actual presence of any bladder or bowel incontinence or pathology associated with lumbosacral radiculopathy. The medical records and oral and written statements of the Veteran indicate that she was certified as an educator and that worked as a substitute schoolteacher but that she did not seek to work as a full-time schoolteacher on account of her back. That said, the report of her April 2013 VA examination shows that the examining clinician determined that there was no impact by her service-connected low back disability on her capacity to obtain and retain work. The Board has considered the totality of the evidence as it relates to the time period pertinent to the claim and finds no objective basis to assign an evaluation greater than 10 percent for the Veteran's service-connected low back disability. While acknowledging her subjective complaints of low back pain and the impact that this pain has on the functional capacity of her thoracolumbar spine, the clinical evidence nevertheless demonstrates that she does not have limitation of forward flexion of her thoracolumbar spine or combined limitation of thoracolumbar spine motion that meets the criteria for a 20 percent evaluation. Although muscle spasm is occasionally present, it is not clinically demonstrated to be severe enough to produce an actual abnormal gait by itself or through guarding behavior. The Veteran occasionally uses a cane to support herself when walking, but no abnormal gait was demonstrated on the examinations of record. There is also no credible evidence of limitation of motion or of pain on use or flare-ups that result in limitation of motion to the extent that the lumbosacral spine disability would warrant a higher rating. 38 C.F.R. §§ 4.40 , 4.45, 4.59; DeLuca v. Brown, 8 Vet. App. 202 (1995). It is not disputed that the Veteran has limited motion of the thoracolumbar spine and that there is pain on motion and loss of function. Yet, the Board finds that the 10 percent disability rating adequately compensates her for her painful motion and functional loss. The VA medical examinations of 2006 - 2013 all demonstrate limitation of forward flexion, backward extension, right and left lateral flexion and rotation that factored in the complaints of pain. The VA examinations also described the Veteran as experiencing pain on motion and pain after performing at least three repetitions. However, examinations do not demonstrate that there was additional loss of motion or weakness following those repetitions. The provisions of 38 C.F.R. §§ 4.40 and 4.45 have been considered, but they do not provide a basis for the assignment of a higher rating under these circumstances. Indeed, the Court clarified that there is a difference between pain that may exist in joint motion as opposed to pain that actually places additional limitation of the particular range of motion. Mitchell v. Shinseki, 25 Vet. App. 32 (2011). The Court specifically discounted the notion that the highest disability ratings are warranted where pain is merely evident as it would lead to potentially "absurd results." Id. at 43 (limiting the scope and application of its prior holding in Lichtenfels v. Derwinski, 1 Vet. App. 484 (1991)). It was stated that 38 C.F.R. § 4.40 provides that joint pain alone, and even pain throughout the entire range of motion, but without evidence of decreased functional ability, does not warrant the minimum compensable rating. In this case, a higher rating based on guarding for anticipated pain without any quantifiable loss due to actual pain does not serve as basis for an increased rating. The Veteran was already being adequately compensated for pain. The record also fails to show that IVDS associated with the radiculopathic component of the Veteran's disability has been manifested by incapacitating episodes. VA treatment records and the VA examination are both negative for any findings of incapacitation due to IVDS. Also, in the absence of any clinical demonstration of actual neurological deficit or impairment affecting either lower extremity attributable to the service-connected low back pain, assignment of a separate and individual rating on the basis of paralysis of the peripheral nerves of the lower extremities is not warranted. Aside the Veteran's radiculopathy, the Board finds that there is no competent medical evidence of any associated objective neurologic abnormalities as a result of the lumbar strain to be separately evaluated under an appropriate diagnostic code. The VA examinations pertinent to the period at issue specifically note that there were no neurologic abnormalities such bowel or bladder pathology present. Therefore, in view of the foregoing discussion, the Veteran's claim for an evaluation greater than 10 percent for service-connected low back pain must be denied. Because the evidence in this case is not approximately balanced with respect to the merits of this claim, the benefit-of-the- doubt doctrine does not apply. 38 U.S.C.A. § 5107(b) (West 2002); 38 C.F.R. § 3.102 (2012); Gilbert v. Derwinski, 1 Vet. App. 49 (1990). Individual unemployability and extraschedular consideration. To the extent that a claim for individual unemployability has been raised by the record, pursuant to Rice v. Shinseki, 22 Vet. App. 447 (2009), the Board notes that the Veteran's low back disorder (rated 10 percent disabling) and mitral valve prolapse (rated 10 percent disabling) are her only service-connected disabilities and that they do not meet the minimal criteria for a total disability rating based on individual unemployability due to service-connected disabilities (TDIU) under 38 C.F.R. § 4.16(a) (2012), as neither have ever produced a combined rating under 38 C.F.R. § 4.25 of more than 20 percent at any time during the pendency of the current claim. Further, the Board finds that that the clinical evidence does not objectively demonstrate or otherwise indicate that the Veteran is unable to secure and follow a substantially gainful occupation by reason of her service-connected disabilities. Accordingly, the Board concludes that no further discussion of entitlement to a TDIU is warranted at this time. The Board further finds that there is no evidence of an exceptional or unusual disability picture associated with the Veteran's service-connected low back disability, with such related factors as marked interference with employment or frequent periods of hospitalization, as to render impractical the application of the regular schedular standards. A rating in excess of the assigned schedular evaluation for the Veteran's service-connected low back disability may be granted when it is demonstrated that the particular disability presents such an exceptional or unusual disability picture with such related factors as marked interference with employment or frequent periods of hospitalization as to render impractical the application of the regular schedular standards. See 38 C.F.R. § 3.321(b)(1) (2012). To accord justice in an exceptional case where the schedular standards are found to be inadequate, the field station is authorized to refer the case to the Under Secretary for Benefits or the Director, Compensation and Pension Service, for assignment of an extraschedular evaluation commensurate with the average earning capacity impairment. 38 C.F.R. § 3.321(b)(1) (2012). The Court has held that the Board is precluded by regulation from assigning an extraschedular rating under 38 C.F.R. § 3.321(b)(1) (2012) in the first instance; however, the Board is not precluded from raising this question, and in fact is obligated to liberally read all documents and oral testimony of record and identify all potential theories of entitlement to a benefit under the law and regulations. See Floyd v. Brown, 9 Vet. App. 88 (1996). The Court further held that the Board must address referral under 38 C.F.R. § 3.321(b)(1) only where circumstances are presented which the Director of VA's Compensation and Pension Service might consider exceptional or unusual. See Shipwash v. Brown, 8 Vet. App. 218, 277 (1995). Extraschedular consideration involves a three step analysis. Thun v. Peake, 22 Vet. App. 111 (2008). First, the Board or the RO must determine whether the schedular rating criteria reasonably describe the Veteran's disability level and symptomatology. Id. at 115. If the schedular rating criteria do reasonably describe the Veteran's disability level and symptomatology, the assigned schedular evaluation is adequate, referral for extraschedular consideration is not required, and the analysis stops. Id. If the RO or the Board finds that the schedular evaluation does not contemplate the Veteran's level of disability and symptomatology, then either the RO or the Board must determine whether the Veteran's exceptional disability picture includes other related factors such as marked interference with employment and frequent periods of hospitalization. Id. at 116. If this is the case, then the RO or the Board must refer the matter to the Under Secretary for Benefits or the Director of the Compensation and Pension Service for the third step of the analysis, determining whether justice requires assignment of an extraschedular rating. Id. In the current appeal, the Board finds that there is no evidence that the Veteran's service-connected low back disability has presented such an unusual or exceptional disability picture at any time between June 2005 to the present, so as to require consideration of an extraschedular evaluation pursuant to the provisions of 38 C.F.R. § 3.321(b) (2012). Specifically, the evidence of record does not indicate the Veteran is frequently hospitalized for her service-connected low back disability. The Veteran has reported that she is able to work part-time as a substitute teacher. However, the clinical and testimonial evidence does not indicate marked interference with her ability to work at a desk in the capacity of an educator. The criteria of the applicable rating schedules are therefore deemed to adequately contemplate the Veteran's present level of impairment due to the low back disability at issue, as individually considered. As such, the Board cannot concede that the Veteran's service-connected low back pain, standing by itself, causes marked interference with her employment capacity. Higher ratings are available for the Veteran's low back disability, but for the reasons described in the above decision, higher ratings were denied in this case. The clinical evidence and medical opinions fail to show that the disability picture created by the low back disability, in isolation, is of an exceptional or unusual nature. Having reviewed the record with these mandates in mind, the Board finds that the schedular rating presently assigned to the low back disability adequately reflects the state of its impairment for the period to which it is applied, and that there is no evidentiary basis for referral of the case for extraschedular consideration with regard to this issue. ORDER An increased evaluation in excess of 10 percent for low back pain is denied. ____________________________________________ THERESA M.
