Study Arms (2)
Control
Subjects who are collegiate level athletes who do not have a concussion and are currently playing a contact-collision sport.
Concussed
Subjects who have recently suffered a sports-related concussion and are currently a collegiate athlete playing a contact-collision sport.
Eligibility Criteria
Collegiate Athletes who are currently playing a contact-collision sport.
You may qualify if:
- Student athletes actively participating in collegiate sports. Subjects should be wiling to provide informed consent for participation in the study.
You may not qualify if:
- Participants who are unable to play as a result of injury. Presence of irregular heart beat.
