Abstract

The purpose of this study was to capture on-field head impact data from the HIT System and xPatch concurrently in order to gain a broader understanding of their ability to appropriately measure head impact biomechanics. Nine collegiate football players participated in this study. We used video analysis to record head impacts during three game sessions. Our findings reveal a moderate correlation between the HIT System and xPatch in measuring linear acceleration and HITsp, and low correlation in measuring rotational acceleration. Our findings also reveal poor agreement in impact location between the recorded impact location of the HIT System and xPatch, and the actual impact location verified by video analysis. Additional analyses revealed the number of false positive head impacts recorded and allowed us to estimate total head impact exposure. Future research should investigate head impact biomechanics in non-helmeted sports and test the xPatch in a laboratory setting.
