Table 5.

Comparison of athletes with concussion to healthy athletes on smooth pursuit parameters. Velocity gain= eye/target velocity. Position gain=eye/target position. Sample sizes below each variable represent the number of non-concussed and number of concussed, respectively, individuals in each analysis, representing the number of individuals from each group who could complete the task.
