Occupational medicine will be a big focus of Knoxville Hospital and Clinic’s new physical therapy team. Steve Cassabaum, with 21stCentury Rehab, tells KNIA/KRLS News that they’ve been successful in the past in helping local business reduce costs and improve employee health. He says part of what they do involves examining the tasks employees perform. Based on those tasks, Cassabaum says they help employers create screen tests to ensure potential hires can perform their duties without injury.
