摘要

Repetitive subconcussive head impacts were theorized to influence injury tolerance among football players. Higher number of subconcussive head impacts through routine participation have been associated with decreased cognitive abilities. Therefore, it is important to study and quantify differences in head impact history among concussed and non-concussed athletes to better understand the influence of subconcussive head impacts on concussion tolerance. Football athletes from four NCAA Division III colleges and four high schools (n=426) were recruited to participate in the study during 2015 and 2016 football seasons. All participants were issued helmets outfitted with Head Impact Telemetry System (Simbex, Lebanon, NH) sensors designed to continuously monitor and record kinematics associated with head impacts above 10g linear acceleration. Head impact data were stored on the sensors and then wirelessly transmitted to a sideline receiver for processing. Head impact exposure data were collected during games and practices. Concussive impacts were identified using incident details, HITs data, and videos of the event. A total of 248,253 head impacts and 20 concussions were captured with HITS during two seasons of data collection. There was no significant difference in average impacts per session between concussed and non-concussed athletes. However, the number of impacts sustained by a concussed athlete on day of injury was significantly higher than average impacts per session for non-concussed athletes. Cumulative risk metric showed that 19 out of 20 concussed athletes had greater than 50% risk of sustaining a concussion based on the frequency and magnitude of impacts on day of injury. The data from the study shows that cumulative risk metric derived from subconcussive head impact exposure can help in better understanding the risk of injury to an athlete.
