Concussion Screen Use Recovery Time

A two-year parallel randomized clinical trial study to examine the effect of screen time (ST) restriction, exercise alone, and combined ST-restricted-exercise when compared to stretching only (control group) on sports related concussion recovery time among adolescents aged 12 to 17 years. Study hypothesis 1 - There will be significant differences between the treatment and the control arms' mean recovery time (days). Study hypothesis 2 - The ST-restricted \& exercise treatment arm will have a significantly shorter mean recovery time (days) compared with the other treatment arms and control arm.
