Based on a comprehensive review of the evidence, including Claimant's testimony, the expert medical opinions and depositions, the medical records and bills, the other documentation, and the testimony of Employer's witness, as well as my personal observations of Claimant and the other witness at hearing, I find:
1) Claimant is a 54-year-old male who worked for Employer for approximately 17 years, through 2008, as an audio technician. Prior to being hired as a regular full-time employee by Employer in 1991, he performed some freelance work for them in the 1980s. Claimant testified that his work days can range anywhere from 4 to 8 hours per day, and up to 17 hours per day, depending on the job. He states that his minimum workday is 4 hours per day. Claimant testified that he believes it is more complicated and hand-intensive to operate an audio board during a business meeting than a concert.
2) Claimant testified that his job duties include set up, repair and operation of audio boards for business conferences and concerts. Claimant testified that his job duties involve standing on a riser in the back of an auditorium during a business meeting or concert, and operating an audio board with his hands by adjusting the various sound levels on an audio board. He adjusts levels, faders, knobs and handles throughout the meeting or performance. Claimant testified that his hands are in a cocked position and he leans against the board as he maneuvers the fader buttons up and down the board with his fingers.
3) Medical treatment records from Dr. Robert Tague (Exhibits D and 3), Claimant's family physician, document treatment Claimant had for both diabetes and bilateral hand complaints going back to 1994. On April 15, 1994, Dr. Tague noted that Claimant complained of "carpal tunnel pain" which was present for 4 months, and
which would awaken him at night. Claimant described his job duties as "variable." Blood tests run on that date showed high glucose levels and in subsequent notes, there are diagnoses of "DM" (diabetes mellitus) for which he was apparently prescribed diet and exercise. Claimant's weight on that date was 233 pounds. Claimant's continued blood tests, and office notes through the rest of the 1990's, showed that the glucose levels would sometimes be down in the normal range, and at other times would be slightly high. Claimant initially lost some weight ( 30 pounds) and the hand complaints were apparently not as troublesome because they were not referenced again in the records until 2002/2003. There is an additional mention of carpal tunnel, left greater than right, on September 21, 1998, but it is under a section of the note entitled "PMH" which stands for past medical history. There was no contemporaneous reference to carpal tunnel syndrome complaints at that visit.
4) Claimant testified that in 2003 he began to have more severe problems with his wrists and so he sought further treatment for his complaints.
5) Dr. Tague sent Claimant for EMG and Nerve Conduction Study testing on the upper extremities to St. Anthony's Medical Center (Exhibit I) on October 16, 2003. The testing revealed mild delays on the right median nerve and moderate delays on the left median nerve, consistent with mild right carpal tunnel syndrome and severe left carpal tunnel syndrome.
6) Claimant was then referred to Dr. Daniel Kitchens at Cardinal Neurosurgery \& Spine, Inc. (Exhibits E and 4) for further evaluation of his hand complaints. Dr. Kitchens examined Claimant on November 25, 2003. He noted a several year history of left hand pain, numbness and tingling, and a more recent onset of right hand complaints. Dr. Kitchens noted that, "The numbness and tingling come[s] on when he is playing the bass and is flexing his wrist and using his fingers." There is absolutely no reference to his work causing any of the hand problems, and in fact, the report indicates that, "he reports no occupational concerns." Dr. Kitchens diagnosed bilateral carpal tunnel syndrome, severe on the left and mild on the right. He discussed treatment options with Claimant including surgery versus conservative care. Claimant wanted to consider his options and was instructed to contact Dr. Kitchens if he decided to proceed with the surgery.
