This study examined combined eye-head gaze shifts (CEHG) in student athletes to determine if CEHG function is impacted by mild traumatic brain injury (concussion). The researchers hypothesized that CEHG velocity, accuracy, and latency would worsen following a concussion. They also hypothesized these metrics would decline in uninjured athletes over a sports season. CEHG was measured in tasks of varying difficulty in student athletes before and after their season. Preliminary results found changes in one concussed athlete's CEHG but little change in uninjured athletes. However, directional errors increased from pre- to post-season in uninjured athletes, suggesting a potential seasonal effect on CEHG not due to
