Study Details

Brief summary:

The purpose of this study is to determine the value of including dynamic vision testing into California State University, Northridge (CSUN) Athletics' established concussion protocol. The study's hypotheses are 1) dynamic vision testing will reveal vision impairments right after a person sustains a concussion, 2) these impairments may still be present upon clearance to return to play.
