“…Each head impact video was analyzed independently by three trained raters using a reliable and validated questionnaire 43 . We previously describe the nature and inter-rater reliability of the questionnaire and procedures for training raters 30 . For the eight questionnaire items included in this study, the total percent agreement (TPA) and free marginal kappa 44 ranged between 67 and 97% and 0.31-0.93, respectively.…”

“…Furthermore, previous studies were limited by the use of a single camera that followed the puck, and the high likelihood of missing impact events occurring outside of the camera’s field of view. Using five cameras to capture the entire ice surface, we recently reported that the head was impacted nearly twice as often by the (gloved) hand than the shoulder/upper arm or elbow/forearm, and the head impacted the glass four times more often than the boards 30 . Furthermore, we found that impacts to the side of the head were four times more common than impacts to the back or front.…”

Improved evidence on the most common and severe types of head impacts in ice hockey can guide efforts to preserve brain health through improvements in protective gear, rink design, player training, and rules of play. In this observational cohort study of men’s university hockey, we compared video evidence on the circumstances of 234 head impacts to measures of head impact severity (peak linear accelerations and rotational velocities) from helmet-mounted sensors (GForceTracker). Videos were analyzed with a validated questionnaire, and paired with helmet sensor data. Shoulder-to-head impacts were more common than hand- or elbow-, but there were no differences in head impact severity between upper limb contact sites (p ≥ 0.2). Head-to-glass impacts were nearly four times more common, and just as severe as head-to-board impacts (p ≥ 0.4). Head impacts resulting in major penalties (versus no penalty), or visible signs of concussion (versus no signs), involved greater head rotational velocities (p = 0.038 and 0.049, respectively). Head impacts occurred most often to the side of the head, along the boards to players in their offensive zone without puck possession. Head impact severity did not differ between cases where the head was (versus was not) the primary site of contact (p ≥ 0.6). Furthermore, penalties were called in only 4% of cases where the head was the initial point of contact. Accordingly, rules that focus on primary targeting of the head, while important and in need of improved enforcement, offer a limited solution.

Objective: To describe the epidemiology of body checking injuries in the National Collegiate Athletic Association (NCAA) Men's Ice Hockey. Design: Secondary data analysis of historical cohort data. Setting: A convenience sample of injuries in NCAA Men's Ice Hockey during the 2009/10 to 2019/20 academic years. Patients (or Participants) NCAA student-athletes. Independent Variables: Event type, season, time loss, body part, diagnosis, player position, and mechanism. Main Outcome Measures: This study examined injuries that occurred during practice or competition, regardless of time loss, reported to the NCAA Injury Surveillance Program. Injury counts, rates, and proportions were used. The injury rate and proportion ratios with 95% confidence intervals were also constructed. Three independent logistic regression models were constructed to examine differential odds of time loss (≥1 day; TL) injury and the 2 most common injuries, between body checking injuries and all other injuries. Results: Overall, 1290 body checking injuries (rate = 1.59/1000 athlete-exposures) were reported during the study period. Most were attributed to the upper extremity (42%) or head/neck (27%). The competition injury rate generally decreased after 2012/13. After adjusting for covariates, odds of (1) a TL injury was lower and (2) an acromioclavicular sprain was higher among body checking injuries as compared with injuries attributed to all other activities. Odds of concussion was not associated with body checking injuries. Conclusions: Body checking injuries were frequently attributed to the head/neck and upper extremities, and the rate of these injuries during competition appeared to be decreasing. Still, improvements in helmet and shoulder pad technology may further improve health and safety.
