Acute Concussion Therapy Intervention Training in Healthy and Concussed Participants

Healthy and concussed participants will be randomized to ACTIVE training (intervention) or control (no intervention) groups. Participants, regardless of group assignment, will receive clinical symptom, balance, and cognitive evaluations as well as a progressive exercise assessment at study outset. Concussed participants will enroll into the study within three days of injury and study participation will termination following 24 consecutive hours with no reported concussive symptoms. Healthy participants will have arbitrary start dates and will terminate the study 10-14 days later to approximate the general length of concussion recovery and, therefore, make the time between session in the healthy and concussed cohorts as equivalent as possible. Participants in the intervention group will complete stationary cycle ergometer workouts for 30 mins at least 3 days per week between testing sessions. Healthy participants will complete six ACTIVE training sessions, while concussed participants will complete ACTIVE training at least three days per week until asymptomatic. Concussed control participants will follow physician guidelines for rest and activity, while healthy control participants will be asked to follow their typical routines for rest and activity. Participants will repeat the identical testing session assessments prior to study termination.
