(Under the direction of Dr. Kevin Guskiewicz)
Evaluation of concussion is a complex process involving clinical, cognitive, symptom, and postural assessments. This study examined inter-instrument reliability of the X2Impact Mouthguard accelerometer to the already accepted Helmet Impact Telemetry (HIT) System in quantitatively recording head impact biomechanics. Ten collegiate varsity football players at UNC were fitted with both the X2Impact Mouthguard and the HIT system for two months during the fall football season. During this time both systems provided concurrent data collection of the peak linear acceleration, peak rotational acceleration and impact location. Upon completion of data collection a mixed model analysis of variance (ANOVA) will be run in order to calculate the intraclass coeffecients (ICC) between the peak linear acceleration, peak rotational acceleration and impact location reported for the matched impacts by the two systems.
