In Central Park Lodge v. Workers' Compensation Appeal Board (Robinson), 718 A.2d 368 (Pa. Cmwlth. 1998), Robinson was injured at work when a metal gate fell on her head. It was conclusively established in the claim petition proceeding that Robinson was disabled due to work-related injuries to her neck, back, and head, and the head injuries involved a concussion and post-concussion syndrome. Central Park Lodge's expert testimony only addressed claimant's neck and back injuries and failed to address Robinson's head injury (i.e., her concussion and post-concussion syndrome). On those facts, this Court affirmed the board's decision that Central Park Lodge's petition to terminate was not supported by sufficient evidence.
