- With regard to occupational disease due to repetitive motion, if the exposure to the repetitive motion which is found to be the cause of the injury is for a period of less than three months and the evidence demonstrates that the exposure to the repetitive motion with the immediate prior employer was the prevailing factor in causing the injury, the prior employer shall be liable for such occupational disease.
Employee was employed with SystemAire from January 3, 2005 to August 20, 2007. His work duties exposed him to repetitive motion activities involving his hands, arms, and raising his arms above his head involving his shoulders. These repetitive motion activities have been found by credible medical opinion to be the prevailing factor in causing the conditions of carpal tunnel syndrome, cubital tunnel syndrome, and thoracic outlet syndrome (TOS).
Employee experienced symptoms consistent with carpal tunnel and cubital tunnel syndromes beginning in 2006, and was initially treated by employer's authorized medical providers. Evidence of disability due to carpal and cubital tunnel syndromes and thoracic outlet syndrome arose in 2006-2007, and employee was unable to work or unable to perform certain work duties during periods of his SystemAire employment. He underwent surgery for both wrists and elbows in early 2007, while employed by employer, SystemAire. As of July 24, 2007, Dr. Susan MacKinnon who had been treating employee for his wrist and elbow symptoms, began to further consider TOS, having documented his inability to raise his arms above his head, and his tendency to drop things. Dr. MacKinnon testified this was consistent with TOS. Medical records in 2006 and the summer and fall of 2007, identify symptoms consistent with TOS, and note evidence of disability resulting from the condition affecting his ability to perform his duties.

Washington University medical providers, Dr. MacKinnon, M.D. and Renee Ivens, P.T. D.P.T. both opined that employee's symptoms were disabling in July through September 2007. Dr. MacKinnon explained that the symptoms of carpal and cubital tunnel and TOS are similar and that a physician may initially focus on one aspect, depending on how the patient presents his worst symptoms. Renee Ivens noted on September 27, 2007 that his neural symptoms were limiting his ability to work safely as a sheet metal worker.
After leaving SystemAire due to lay-off, employee was employed for about four days with a firm referred to as ICON. The duties as a sheet metal worker were the same as at SystemAire. Employee credibly testified in his May 2009 deposition, that his employment ended with ICON at least in part, because of pain and difficulty in performing the work duties.² Transcript page 5028. Employee then obtained a job through the union hall with American Sheet Metal (ASM) from October 25, 2007 to October 31, 2007, doing the same duties as in his prior sheet metal work position with SystemAire. He was then off work until he was hired by Harke in late November 2007. Employee's work with each of the interim employers, ICON and ASM, was for less than three months. The evidence supports the finding that the work with the previous employer, SystemAire, was the prevailing factor in causing all the injuries/occupational diseases and evidence of disability first arose during that employment.

² We note this finding is different than the administrative law judge's finding, and replace his finding at page 8, with our own. Employee's memory on this issue changed as time elapsed, but we deem the testimony nearest in time to the event to be more persuasive.
