Dr. Chmielewski’s primary research investigates the rehabilitation of traumatic knee injuries, with a focus on anterior cruciate ligament (ACL) rupture and meniscal tear. This research has investigated neuromuscular, musculoskeletal, biomechanical and psychosocial contributions to functional outcome and markers of post-traumatic osteoarthritis using a combination of clinical and laboratory approaches. A second line of research investigates musculoskeletal screenings of athletes to identify strength, flexibility and movement impairments that could increase injury risk.
