Sponsor's own description
The purpose of the proposed study is to evaluate the efficacy of Brock String therapy prescribed in the acute stage of concussion recovery can improve clinical outcomes among patients with receded near point of convergence (NPC). Aim 1: Determine if participants receiving the Brock String have more significant improvements in NPC measurements at follow up 7-10 days post injury. Aim 2: Determine if participants receiving the Brock String 1) improve on computerized neurocognitive test scores from initial visit (\<48 hours post injury) to follow up visit (7-10 days post injury) compared to control participants, and 2) have reduced recovery time (i.e., days from injury until return to play) compared to control participants.
