The median/99th percentile of (PLA) and (PAA) were 20/50 g, and 1700 rad/s2/4600 rad/s2. There were no diagnosed concussions. One athlete was removed by athletic training staff after a significant head impact.Conclusions In the future, head impact dynamics data must be correlated with sensitive and specific assessments of cognitive, executive, vision and balance parameters in order to determine the concussion assessment threshold.Disclosures: Dr. Bartsch has nothing to disclose.
