Participants\u2019 blink reflex was assessed at preseason physicals and then again within 48 hours of concussive head injury using the EyeStat. Thirty-two cadets with SRC (mean age 20.1 years, 78% male) and 6 cadets with a repeat SRC during the enrollment period (mean age 21.7 years, 83% male) were assessed, a mean of 1 day post injury, and included in the analysis.

No significant difference was observed for oscillations (P = .167). Although underpowered, our exploratory analysis suggests that this finding was not affected by participant age or sex. In repeat concussions, ipsilateral latency had a similar trend, but differential latency did not.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The blink reflex is affected after SRC, and its assessment may provide objective data to aid diagnosis.
