Their findings, reported in the journal Scientific Reports , should help to inform improvements in injury prevention. In a follow-up to their previous study on how hockey head impacts occur, researchers returned to a Burnaby rink to follow 43 university men's hockey players over another three seasons (2016-2019). This time they compared video evidence-gleaned from cameras strategically placed around the rink to capture head impacts during play-with data from helmet-mounted sensors, or GForceTrackers, which measured head linear accelerations and rotational velocities. In all, 234 head impact incidents were recorded. The head impact videos were analyzed with a validated questionnaire that probed situational factors before, during, and after impact to the head. Videos were then paired with corresponding helmet sensor data.
