Opinion:
OPINION BY
Judge LEAVITT.
Neil Folmer (Claimant) petitions for review of an adjudication of the Workers' Compensation Appeal Board (Board) terminating his benefits. In doing so, the Board affirmed the decision of the Workers' Compensation Judge (WCJ) that Swift Transportation, Inc. (Employer) proved by competent medical evidence that Claimant was completely recovered from his work-related injury. Indeed, the WCJ found that Claimant was a malingerer who magnified symptoms that could not be corroborated by objective medical evidence. In this appeal, we are asked to consider, inter alia, how an employer proves a change in a claimant's physical condition, where the claimant's work-related injury consists primarily of pain and dizziness.
On October 23, 1995, Claimant, a truck driver, sustained a work-related injury when he was hit in the face by a box of crowbars while unloading a truck. Claimant filed a claim petition requesting full disability benefits. On May 15, 1998, the WCJ granted the petition, concluding that Claimant was totally disabled by his work-related injury, which was found to be "positional vertigo," "cervical disc syndrome or cervical myalgia and tension headache." WCJ Decision, 5/15/98, at 12; Finding of Fact 13. The WCJ accepted as credible the opinion of Claimant's treating chiropractor that a March 8, 1996, MRI revealed a small central disc protrusion or herniation at the C4-5 level of the spine. The WCJ also found that Claimant's vertigo was caused by vascular compression of the eighth cranial nerve.
In June 2001, Employer filed a termination petition alleging that Claimant fully recovered from his work-related injury as of May 31, 2001. Employer's medical experts opined that Claimant was fully recovered, and Claimant's medical experts opined to the opposite.
One of Claimant's experts, Joseph Eshleman, D.O., interpreted a 1999 cervical MRI as ruling out a disc herniation at any level or a nerve root impingement. On the other hand, he construed an EMG and nerve conduction study from 1999 to show radiculopathy at the C-6 vertebra. Dr. Eshleman also believed that vestibular testing done on Claimant in January 2000 had increased Claimant's vertigo.
Another of Claimant's experts, Joseph Wapenski, M.D., found that Claimant suffered "some very subtle nystagmus," which is a jerking of the eyes that confirms the presence of vertigo. WCJ Decision, 9/18/03, at 8; Finding of Fact 11. However, Dr. Wapenski found that Claimant's nystagmus, which is objective evidence of vertigo, was not always present; sometimes it appeared and sometimes it did not, depending on the day of the test.
Claimant's last expert, Leslie Tar, M.D., testified that Claimant had taut, ropy bands of muscle in the cervical area, which was objective evidence of cervical myalgia. Because Claimant did not have nerve root impingement, Dr. Tar believed that Claimant's radiculopathy was caused by muscle spasms in the cervical area.
The WCJ denied the termination petition on September 18, 2003. However, the WCJ was troubled that Claimant's medical evidence was stale and that Claimant had not undergone any recent diagnostic testing. The WCJ specifically explained as follows:
[T]his is a close case to decide although at this time I am willing to give the claimant the benefit of the doubt... .Without more recent diagnostic testing of EMG and nerve conduction studies and/or vestibular testing, I am not persuaded or convinced the claimant has fully recovered from all of his com-pensable work injuries.
WCJ Decision, 9/18/03, at 12; Finding of Fact 13. This discussion is difficult to follow inasmuch as the stale tests referred to by the WCJ were those of Claimant's medical experts. Further, the EMG referred to by the WCJ pertained to Claimant's C-6 radiculopathy, which was not one of his accepted work injuries, and Claimant's own expert agreed that he did not have a C-6 disc herniation.
On August 9, 2004, Employer filed a second termination petition, which we consider in this appeal. Employer alleged that Claimant had fully recovered as of December 11, 2003, from any residual problem related to his October 23, 1995, work-related injury.
In support of its petition, Employer presented the testimony of Howard J. Senter, M.D., board-certified in neurological surgery, who conducted a thorough examination of Claimant on December 11, 2003. Claimant complained of tunnel vision, hearing loss, dizziness, weakness in his hands, numbness in his hands and arms, neck pain and headaches. Dr. Senter performed a neurologic examination and a mechanical examination, both of which required a battery of tests. Dr. Senter tested Claimant's cranial nerves and vestibular function, which affect balance and coordination. The findings were normal. Claimant exhibited smooth eye movements, ie., the absence of nystagmus, full visual fields, normal optic nerve, and symmetric face. The tests ruled out positional vertigo; vestibular, cerebellar or balance dysfunction; and any problem with Claimant's eighth cranial nerve. Dr. Senter explained that when nystagmus is due to a problem with the eighth cranial nerve, it should be present all the time and does not come and go, as Claimant's physician, Dr. Wapenski, had described in the prior termination hearing.
Dr. Senter also examined Claimant's neck, which exhibited a normal range of motion. He did not find taut muscles or any evidence of pain or muscle spasms, thereby ruling out C-6 radiculopathy, which was not even a work-related injury. Dr. Senter looked for evidence of neuro-logic impairment in the nerves or muscles of the upper extremity and found none; Claimant exhibited normal reflexes, strength and sensation in both upper extremities. Dr. Senter reviewed the report of an MRI done on Claimant's neck that did not show a herniated disc but, rather, degenerative disc disease, which was normal for a person of Claimant's age.
Some of Claimant's test results were not normal, but Dr. Senter explained that Claimant was faking the results. Indeed, Dr. Senter testified that he found Claimant was malingering and magnifying his symptoms throughout the examination. We consider only some examples of those false symptoms, as a complete list would be too lengthy.
Although Claimant complained of dizziness, his smooth eye movements ruled out vertigo resulting from a cranial nerve problem or any other source. Claimant responded differently to two different tests that checked for the same hearing functions, making the inconsistent results im possible. Claimant demonstrated balance problems during one test and normal balance in another test; again this was impossible because both tests checked the same function but in a different way. Claimant demonstrated normal strength in some muscles and "give away" weakness in other muscles; all the muscles in question, however, were enervated by the same nerve. Muscles enervated by the same nerve will all be weak or all be strong; there can be no combination. Claimant complained of loss of sensation in places that did not make sense because they did not correspond to the way nerves actually run to the muscles. A genuine nerve problem will produce predictable losses of sensation that correspond to the damaged nerve. Based on these and many other inconsistencies in Claimant's test results, Dr. Senter explained that "it is not medically possible for this person to have this combination of neurologic complaints on the basis of any organic disease." Reproduced Record at 136a (R.R. —).
Dr. Senter opined that Claimant did not suffer from positional vertigo resulting from compression of the eighth cranial nerve, cervical disc syndrome or cervical myalgia. With respect to headaches, Dr. Senter explained that Claimant reported only migraine headaches, which could not be related to the work injury. Accordingly, Dr. Senter opined that Claimant was fully recovered and capable of returning to his prior job without restrictions.
Employer also presented the testimony of John B. Talbott, M.D., board-certified in neurology, who examined Claimant on September 20, 2005. That examination ruled out brain problems, pinched nerves, herniated discs, spinal cord involvement or dizziness. Dr. Talbott testified that there were no objective findings to confirm Claimant's numerous subjective complaints. Dr. Talbott found no evidence of nystagmus to corroborate Claimant's complaints of vertigo. Further, Dr. Talbott stated that although Claimant exhibited symptoms of sensory loss, he did so in an inconsistent fashion and in a way that did not conform to the anatomy of the human spinal cord. Dr. Talbott opined that Claimant was fully recovered from his work-related injuries. In fact, Dr. Talbott believed that Claimant had been fully recovered when he did an earlier evaluation in March 2000.
Claimant testified that he continues to experience headaches, dizziness and tunnel vision. He stated that his condition is "about the same" as the last time he testified before the WCJ. WCJ Decision, 4/27/06, at 2; Finding of Fact 4.
On April 27, 2006, the same WCJ who heard the first termination petition decided, this time, to grant Employer's termination petition. The WCJ explained that
in my last Decision of September 18, 2003, in the [employer's] Termination Petition, I found that it was a close case to decide although at that time, I was willing to give the claimant the benefit of the doubt and found that the [employer] had not met its required burden of proof for a termination of compensation benefits as of May 31, 2001. I am now convinced that the claimant has symptom magnification and is a malingerer as testified to by Dr. Senter and as corroborated by the testimony of Dr. Talbott.
WCJ Decision, 4/27/06, at 11; Finding of Fact 17 (emphasis added). The WCJ noted that he himself witnessed the inconsistencies in Claimant's behavior to which Drs. Senter and Talbott had testified. Claimant exhibited balance problems in the presence of the WCJ in the hearing room; however, Claimant walked without any difficulty when he did not know that the WCJ was watching him. The WCJ rejected Claimant's complaints as not credible. He also rejected the testimony of Claimant's physicians as not credible. The WCJ credited the testimony of Dr. Senter and Dr. Talbott, finding Claimant's subjective complaints to lack any objective basis and to be false. He found Claimant was capable of returning to his prior job without restrictions.
Claimant appealed, and the Board affirmed. In doing so, the Board determined that the credible testimony of Dr. Senter and Dr. Talbott was legally competent and sufficient to support a termination of benefits. In its opinion, the Board referred to King v. Workmen's Compensation Appeal Board (K-Mart Corp.), 549 Pa. 75, 700 A.2d 431 (1997), wherein the Supreme Court held that an employer is not barred by collateral estoppel from filing a second termination petition. The employer has to prove that as of a new date, the claimant's work-related disability has ceased. Claimant then petitioned for this Court's review.
On appeal, Claimant presents two issues for our consideration. First, he argues that King has been overruled by Lewis v. Workers' Compensation Appeal Board (Giles & Ransome, Inc.), 591 Pa. 490, 919 A.2d 922 (2007). In Lewis, our Supreme Court held that in a second termination proceeding, an employer must show that the claimant's physical condition has changed since the prior denial of a termination. Claimant argues that Employer did not produce such evidence and, therefore, the Board's decision must be reversed under Lewis. Second, Claimant contends that the medical opinions relied upon by the WCJ were incompetent because they failed to address all of Claimant's adjudicated work injuries. In response, Employer contends that the record supports the WCJ's conclusion that Claimant was fully recovered as of December 11, 2003; that there is no objective basis to support Claimant's subjective complaints; and that Employer did, in fact, show a change in Claimant's physical condition from the prior adverse adjudication.
We begin with Claimant's argument pertaining to Lewis, wherein our Supreme Court clarified that an employer must show a change in a claimant's condition in order to prevail in a second termination petition. Claimant argues that Employer did not show a change in his physical condition after losing its first termination petition, and this requires the Board to be reversed.
In Lewis, the employer filed three petitions to terminate benefits, and each petition was denied by the WCJ. Three days after the Board denied the employer's third termination petition, the employer filed a fourth termination petition again alleging a full recovery. At the hearing on the fourth petition, the employer's medical expert opined that the claimant's work-related injuries were limited to an acute cervical sprain and acute lumbosacral strain, both of which had resolved, and that the claimant's current medical conditions were unrelated to the work injury. Crediting the employer's expert, the WCJ granted the employer's fourth termination petition. The Board and this Court affirmed. The Supreme Court then granted review to consider
whether an employer must demonstrate a change in a claimant's physical condition since the preceding disability adjudication in order to bring a petition to terminate or modify benefits due to a decrease in physical disability.
Lewis, 591 Pa. at 495, 919 A.2d at 925.
Relying on Section 413 of the Workers' Compensation Act, Act of June 2, 1915, P.L. 786, as amended, 77 P.S. § 772, and Kachinski v. Workmen's Compensation Appeal Board (Vepco Construction Co.), 516 Pa. 240, 532 A.2d 374 (1987), the Supreme Court held that an employer must present medical evidence that the claimant's current physical condition has changed from what it was in the previous termination proceeding. Lewis, at 501, 919 A.2d at 928. The Supreme Court defined "change of condition" as "any change in the claimant's physical well being that affects his ability to work." Id. at 497, 919 A.2d at 926.
Faced with an employer that filed serial termination petitions, the Supreme Court in Lewis was concerned that such an employer would recharacterize or disregard the prior adjudicated facts in these serial petitions in order to realize a favorable outcome. It goes without saying that an employer may not, for example, present expert testimony that a claimant's condition, which is unchanged, is not actually work-related as previously adjudicated. Rather, the employer must accept the adjudicated condition and prove recovery from it at a later date; this is what is meant by showing a physical change of condition.
Here, Claimant's disability was adjudicated to be "positional vertigo," "cervical disc syndrome or cervical myalgia, and tension headaches." WCJ Decision, 5/15/98 at 12; Finding of Fact 13. In the first termination proceeding, Employer tried to prove that as of May 31, 2001, Claimant was completely recovered. Employer failed because the WCJ credited Claimant's subjective complaints of pain and difficulty. To prevail in its second termination proceeding, Employer had to present medical evidence to show that after May 31, 2001, Claimant's condition changed. Stated otherwise, Employer's case had to begin with the adjudicated facts found by the WCJ in the first termination petition and work forward in time to show the required change. Lewis, 591 Pa. at 501, 503, 919 A.2d at 928-929. See also Taylor v. Workers' Compensation Appeal Board (Servistar Corp.), 883 A.2d 710, 713 (Pa.Cmwlth.2005) (citation omitted) (explaining that where a claimant seeks a reinstatement after a termination of benefits, he must prove that his disability has increased or recurred and that his physical condition has actually changed "since the prior decision.")
Both Drs. Senter and Talbott, who examined Claimant in 2003 and 2005 respectively, testified that Claimant's complaints were either false or not related to his work injury, ie., the migraine headaches. Dr. Senter described in detail the battery of physical tests he performed on Claimant after the first adjudication, and none corroborated Claimant's complaints. They did, however, confirm malingering. In the prior litigation, the objective findings of mild nystagmus and taut neck muscles supported Claimant's subjective complaints. Dr. Senter and Dr. Talbott did not find any nystagmus, and they found Claimant's neck muscles to be normal, not taut. Accordingly, Employer presented medical evidence that showed a "change in the claimant's physical well being that affects his ability to work." Lewis, 591 Pa. at 497, 919 A.2d at 926. Any other holding would mean that an employer could never terminate benefits where, as here, the claimant's injuries consist primarily of subjective complaints, and the credited evidence shows that the claimant is faking.
According to Claimant, however, where a claimant's injuries consist of symptoms that do not have objective support, the employer's ability to show a change in the claimant's condition is limited. Claimant suggests that the employer can show change only with evidence that the claimant no longer had complaints; the claimant discontinued medical treatment; the claimant's own doctor believed he recovered; or surveillance videotapes showed the claimant engaging in activities beyond his abilities given his work injury. Essentially, under Claimant's paradigm an employer will not be able to show a cessation of pain unless the claimant himself acknowledges this cessation.
We reject Claimant's proposed paradigm. Because every case presents a different factual scenario, the evidence needed to show a change of condition will be different in each case. Further, nothing in the Workers' Compensation Act supports Claimant's proposed paradigm. To the contrary, Claimant's proposal would impinge upon the province of the WCJ, who has the statutory responsibility to consider the evidence; determine which evidence is credible; and decide which evidence is entitled to the greatest weight.
Essentially, this ease boils down to the WCJ's credibility determinations. The WCJ rejected Claimant's evidence and accepted, instead, the medical evidence presented by Employer. Employer established to the satisfaction of the WCJ that Claimant was fully recovered. In the first termination proceeding Claimant was found to be suffering pain, and in the second proceeding he was found to be free of pain. This constitutes a change in physical condition, as required by Lewis.
Indeed Lewis's author, Justice Ralph J. Cappy, has said as much. In his concurring opinion in King, 549 Pa. 75, 700 A.2d 431, where the employer obtained a termination by proving a change in claimant's condition, Justice Cappy explained:
[The employer] offered a change in condition since the 1983 termination petition proceedings by presenting expert medical testimony of the 1989 examination of [the claimant] and the expert's conclusion that [the claimant's] subjective complaints of pain, at the time of the second examination, were unfounded. Thus, the Act's requirement of proving a change in condition since the last determination regarding the extent of the claimant's injury was met.
Id. at 83, 700 A.2d at 436 (Cappy, J., concurring) (emphasis added). This is precisely what happened here: the testimony of Employer's experts established that Claimant's "subjective complaints of pain" were unfounded.
Claimant's second argument is that Employer failed to meet its burden of proof for a termination because its medi cal experts did not acknowledge the accepted work injuries and attempted to re-litigate the issue of what is included in the work injury. Specifically, Claimant contends that Dr. Senter's testimony was incompetent because he did not opine that Claimant's headaches do not exist. Further, Claimant notes that Dr. Senter's opinion as to what the 1996 MRI showed, ie., a normal cervical spine for a person of Claimant's age, was contradicted by Claimant's doctor. Claimant then points out that Dr. Talbott stated he was unsure that the 1996 cervical MRI findings related to the work incident. Claimant also points to Dr. Talbott's belief that Claimant's cranial nerves were not damaged in the work incident even though the WCJ found a compression at the eighth cranial nerve caused Claimant's vertigo in the 1998 claim petition. Finally, Claimant notes that Dr. Talbott believed that Claimant was fully recovered in March 2000, which "flies in the face of the WCJ's September 18, 2003, determination" that Claimant was not fully recovered. These points, according to Claimant, render both of Employer's experts incompetent.
In support of his argument, Claimant cites to GA & FC Wagman, Inc. v. Workers' Compensation Appeal Board (Aucker), 785 A.2d 1087 (Pa.Cmwlth.2001) and Gillyard v. Workers' Compensation Appeal Board (Pennsylvania Liquor Control Board), 865 A.2d 991 (Pa.Cmwlth.2005). In Wagman, the employer's medical expert failed to testify that the claimant was fully recovered from exacerbation of pseu-doarthrosis, which was the accepted work injury. In Gillyard, the employer's doctor believed that the work injury was only a lumbar strain/sprain when in reality the work injury also included chronic sciatica with disc bulging. The employer's doctor specifically testified that he was not opining that the claimant was recovered from anything other than the lumbar strain/ sprain. In both cases, the testimony of the employers' medical experts was deemed insufficient to support a termination because the testimony did not address the work-related injury.
However, this is not a Wagman or Gillyard case. This case is more akin to To v. Workers' Compensation Appeal Board (Insaco, Inc.), 819 A.2d 1222 (Pa.Cmwlth. 2003), in which the IME doctor was unable to see, based on the claimant's complaints and description of the mechanism of injury, how a work injury could have occurred. Nevertheless, the employer's doctor testified that there was no connection between the claimant's current complaints and the work incident and no evidence of medical impairment, and therefore, the claimant had fully recovered from any work injury he may have sustained. This Court agreed with the WCJ and the Board that the testimony was competent and supported a finding of full recovery. Id. at 1225.
Dr. Senter and Dr. Talbott did not refuse to acknowledge or to address Claimant's work injury. To the contrary, they addressed each adjudicated injury as well as every observation made by Claimant's medical experts in the first termination proceeding, even those that went beyond Claimant's accepted work injuries.
Claimant's adjudicated work injury is "positional vertigo," "cervical disc syn drome or cervical myalgia, and tension headache." WCJ Decision, 5/15/98 at 12, Finding of Fact 13; WCJ Decision, 4/27/06 at 1, Finding of Fact 3. Dr. Senter specifically checked to see if Claimant continued to suffer from positional vertigo as a result of cranial nerve compression, cervical disc syndrome or cervical myalgia, and he opined that Claimant did not have any such mechanical or neurological impairment.
With respect to Claimant's 1996 cervical MRI, Claimant misapprehends the importance of that test. First, the WCJ never found that Claimant's work injury was a herniated disc, and Claimant's own expert, Dr. Eshelman, testified that none existed as of 1999. Accordingly, whether the 1996 cervical MRI showed a herniation or degenerative disc disease is of no moment. Second, it is not clear whether Dr. Senter reviewed the results of the 1996 MRI or a 1999 MRI. It does not matter because Dr. Senter specifically examined Claimant for a cervical disc problem and found none to exist. Employer was required to show a change from the last termination adjudication, and that proceeding established that Claimant did not have a disc herniation.
With respect to headaches, Claimant correctly points out that Dr. Senter stated, "I have no way of knowing that the patient doesn't have a headache." R.R. 146a. Dr. Senter acknowledged that Claimant could have suffered post-traumatic or tension headaches after being struck in the head with a box of crowbars. However, Claimant did not report tension headaches to Dr. Senter but only migraine headaches, for which he was on medication. Dr. Senter explained that Claimant's migraines could not be related to the work injury. Dr. Senter's opinion on Claimant's headaches as of the date of his examination was sufficient to support a termination. What is more, all of Claimant's complaints were rejected as not credible by the WCJ.
With respect to Dr. Talbott, Claimant correctly notes that he was unsure of the cause of the findings on the 1996 MRI; however, we have already explained that the 1996 MRI is irrelevant because the 1999 MRI showed that Claimant did not have any disc herniation. Claimant is also correct that Dr. Talbott did not believe Claimant damaged any of his cranial nerves in the work incident. In the 1998 claim proceeding, the WCJ found, as fact, that cranial nerve compression caused Claimant's positional vertigo, and thereafter Claimant was treated surgically for cranial nerve compression. It is irrelevant whether Dr. Talbott actually believed Claimant ever damaged his eighth cranial nerve. A medical professional is not required to believe a condition existed; he is merely required to accept as true the adjudicated fact that a condition existed and opine as to whether the condition continues to exist at the time of the examination. To, 819 A.2d 1222. Dr. Talbott tested Claimant for positional vertigo resulting from compression of the eighth cranial nerve and did not find it. Indeed, he testified that Claimant complained about neurological problems in ways that were anatomically impossible. Finally, although Dr. Talbott believed Claimant had been fully recovered in 2000, there is no evidence that he disregarded the WCJ's adjudicated facts in the first termination petition, i.e., that Claimant continued to be disabled by his work-related injuries. Dr. Talbott examined Claimant in 2005 and gave his opinion of his condition as of that date.
In sum, Dr. Senter and Dr. Talbott acknowledged each and every one of Claimant's adjudicated work-related injuries, and each testified that Claimant was fully recovered. They also demonstrated that Claimant's alleged symptoms lacked any objective basis. Their testimony, which was credited by the WCJ, was fully competent to meet Employer's burden of proof for a termination of benefits.
For these reasons, the Board's order is affirmed.
ORDER
AND NOW, this 22nd day of October, 2008, the order of the Workers' Compensation Appeal Board dated February 28, 2007, in the above-captioned matter is hereby AFFIRMED.
."Cervical disc syndrome" is defined as "pain, paresthesias, and sometimes weakness in the area of the distribution of one or more cervical roots, due to pressure of a protruded cervical intervertebral disc." Stedman's Medical Dictionary 1750 (27th ed.2000). "Myal-gia" is defined as "muscular pain." Id. at 1167.
. Claimant underwent two bilateral retromas-toid craniotomy surgeries for decompression of his eighth cranial nerve in May 1997 and in July 1999.
. Vestibular testing is done to determine the presence of positional vertigo.
. According to Claimant's expert, Dr. Tar, the C-6 radiculopathy was caused by muscle spasms.
. Claimant also complained of shoulder pain, but the WCJ had determined that Claimant's shoulder problem was not work-related in the prior proceeding.
.Dr. Senter described malingering as "intent to deceive the observer," and symptom magnification as "expansion upon your symptoms and magnifying them in order to convince the observer that something is going on that really isn't." Reproduced Record at 136a.
. This Court's review is limited to determining whether an error of law or a constitutional violation was committed or whether the findings of fact are supported by substantial, competent evidence. Myers v. Workers' Compensation Appeal Board (University of Pennsylvania and Alexsis, Inc.), 782 A.2d 1108, 1110 n. 1 (Pa.Cmwlth.2001).
. This case was scheduled for argument before the Court en banc in order for the parties to address whether Lewis should be applied prospectively or retroactively and how an employer can show a change in condition when a prior termination was denied on the basis of the claimant's subjective complaints. At argument, Claimant asserted that Lewis is not a change in the law because it overruled King, which had been an "anomaly" decision that was not generally followed. Claimant contended that Lewis is representative of the overall state of the law and requested that this Court not remand the case. Employer maintained that it satisfied its burden of showing a change in condition and that it should prevail under either King or Lewis.
. Section 413 provides in relevant part:
A workers' compensation judge designated by the department may, at any time, modify, reinstate, suspend, or terminate a notice of compensation payable, an original or supplemental agreement or an award of the department or its workers' compensation judge, upon petition filed by either party with the department, upon proof that the disability of an injured employe has increased, decreased, recurred, or has temporarily or finally ceased, or that the status of any dependent has changed.
77 P.S. § 772.
. In Kachinski, the Pennsylvania Supreme Court outlined a four-part test that must be employed in order for an employer to modify workers' compensation benefits. The first part of the test states: "The employer who seeks to modify a claimant's benefits on the basis that he has recovered some or all of this ability must first produce medical evidence of a change in condition." Id. at 252, 532 A.2d at 380 (emphasis added). Therefore, where an employer seeks to modify or terminate benefits because the claimant's medical condition has improved, the employer bears the burden of demonstrating actual physical improvement. Lewis, 591 Pa. at 497, 919 A.2d at 926.
. Employer's evidentiary case did not violate the concern voiced by the Supreme Court that "a disgruntled employer . could repeatedly attack what he considers an erroneous decision of a[WCJ] by filing petitions based on the same evidence ad infinitum, in the hope that one [WCJ] would finally decide in his favor." Lewis, at 497-498, 919 A.2d at 926, (citation omitted). Madame Justice Baldwin's well-reasoned concurring opinion in Lewis suggested that Lewis was too broad in scope, but Lewis was not intended to allow claimants who manufacture symptoms to remain on workers' compensation disability indefinitely.
. Claimant further suggests that because "diagnostic tests" done by his experts corroborated some of Claimant's complaints in the prior proceeding, Employer was required to do its own diagnostic tests. We disagree. In this proceeding, the WCJ rejected the vestibular testing of Claimant's expert because such tests can yield false positives and the outcome can be manipulated by the patient. Diagnostic test results are not infallible and, what is more, diagnostic test results can be interpreted in different ways by different doctors. Claimant was subjected to a battery of clinical physical tests to all areas involved in his work injury, and they did not reveal the continued presence of any one of the work-related injuries.
. In assessing the evidence, the WCJ is the ultimate fact-finder and has complete authority over questions of credibility and evidentiary weight. Davis v. Workers' Compensation Appeal Board (City of Philadelphia), 753 A.2d 905, 909 (Pa.Cmwlth.2000). The WCJ is free to accept, in whole or in part, the testimony of any witness, including medical witnesses. Greenwich Collieries v. Workmen's Compensation Appeal Board (Buck), 664 A.2d 703, 706 (Pa.Cmwlth. 1995).
. The dissent seems to suggest that a change in physical condition can be shown only by a diagnostic test, which, in the parlance of workers' compensation jurisprudence, is a test done by a technician, such as an x-ray or MRI. There are several problems with that suggestion. First, it is for medical experts to determine what tests, whether "pictures" or patient-response type clinical tests, are appropriate to demonstrate change. Second, no test is infallible. An x-ray and MRI must be interpreted by medical experts, and such experts often disagree on the correct interpretation. Likewise, as the WCJ recognized, vestibular testing can be controlled by a patient and yield false positives. In short, there are an array of studies and tests which a medical expert will use to develop his expert opinion. It is not the job of courts to dictate which tests experts should undertake. The dissent notes that Dr. Wapenski found "very mild" nystagmus, but Dr. Wapenski was not found credible by the WCJ.

The WCJ accepted this opinion and granted the second termination petition.
. In a termination proceeding, the employer bears the burden of proving that the claimant fully recovered from his work injury and has no remaining disability, or that any remaining disability is no longer related to the work injury. Campbell v. Workers' Compensation Appeal Board (Antietam Valley Animal Hospital), 705 A.2d 503, 506-507 (Pa.Cmwlth. 1998). A termination of benefits is proper where a medical expert credibly testifies that the claimant fully recovered from his work injury and can return to work without restrictions, and that there are no objective medical findings that either substantiate claims of pain or connect them to the work injury. Udvari v. Workmen's Compensation Appeal Board (USAir, Inc.), 550 Pa. 319, 327, 705 A.2d 1290, 1293 (1997).
