Based upon a comprehensive review of the evidence, my observations of Claimant at hearing, and the application of Missouri law, I find:
I find Claimant sustained an accident arising out of and in the course of employment on September 7, 2007, when he was hit in the head with a pallet jack. Claimant testified credibly that an accident occurred, and there was no evidence to the contrary.
Claimant failed to meet his burden of proving his work injury of September 7, 2007 caused him to lose his hearing. There was no admissible medical evidence to prove that his work injury of September 7, 2007, when he was hit in the head with a pallet jack, caused him to lose hearing in his ear.
Medical causation, not within the common knowledge or experience, must be established by scientific or medical evidence showing the cause and effect relationship between the complained of condition and the asserted cause." Brundige v. Boehringer Ingelheim, 812 S.W.2d 200, 202 [5] (Mo.App.1991). This requires Employee's medical expert to establish the probability Employee's injuries were caused by the work accident. Selby v. Trans World Airlines, Inc., 831 S.W.2d 221, 223 [4] (Mo.App.1992). McGrath v. Satellite Sprinkler Systems Inc., 877 S.W.2d 704, 708 (Mo.App. E.D. 1994)(overruled on other grounds by Hampton v. Big Boy Steel Erection 121 S.W.3d 220 (Mo.2003))
Because the cause of hearing loss is not within the common knowledge or experience of the court, expert medical evidence is necessary to prove the work accident caused Claimant's hearing loss, and Claimant failed to meet his burden of proof.
Because I do not find Claimant met his burden of proof with respect to medical causation, the remaining issues are moot, and the claim for compensation is denied.
