After concussion, progression through the return to sport process is guided by subjective symptom ratings, rather than objective measures of performance. We are currently investigating ways to quantify functional performance in concussed athletes using turning velocity. Here we present case data from three concussed individuals at different stages of recovery and one healthy control. All participants completed a repeated reactive agility task. Performance was assessed using turning velocity (yaw, deg/s) collected using an inertial measurement unit (IMU), and a series of response times captured using timer gates. Due to the exploratory nature, we present descriptive statistics only to provide a foundation for further work in this area.
