This study examined the epidemiology of concussions in high school boys' ice hockey during the 2008/09 to 2016/17 school years.
Prospective cohort study. Athletic trainers from an average 33 high schools annually reported boys' ice hockey concussion and athlete-exposure (AE) data for the High School Reporting Information Online system.
Convenience sample of high school boys' ice hockey programs during the 2008/09 to 2016/17 school years.
High school boys' ice hockey players (aged ∼14-18 years).
Concussion data on event type, injury mechanism, symptom resolution time, and time loss were obtained.
Concussion rates with 95% confidence intervals (CIs) and distributions were calculated.
Overall, 348 concussions were reported in boys' ice hockey during the 2008/09 to 2016/17 academic years, leading to a concussion rate of 0.68/1000 AEs (95% CI, 0.61-0.75). Most occurred in competitions (85.6%), particularly after the first period (72.1% of all competition concussions). Among practice concussions, most occurred after the first hour of practice (60.0%). Most concussions were due to player contact (47.7%) and boards/glass contact (31.9%). Although 69.0% of concussed athletes had symptoms resolve in less than 7 days, only 14.1% returned to activity within a week.
Most concussions occurred within the second and third periods. Preventive strategies that counter an increased risk of concussion due to a greater intensity of gameplay coupled with increased fatigue may be warranted. Moreover, athletes may further benefit from prevention efforts that focus on anticipating impacts during gameplay.
本研究调查了 2008/09 学年至 2016/17 学年期间高中男生冰球运动中脑震荡的流行病学情况。
前瞻性队列研究。每年，来自 33 所普通中学的运动训练员通过“高中报告信息在线系统”报告男生冰球脑震荡和运动员暴露（AE）数据。
2008/09 学年至 2016/17 学年期间的方便抽样高中男生冰球项目。
高中男生冰球运动员（年龄约 14-18 岁）。
获得了关于事件类型、损伤机制、症状缓解时间和时间损失的脑震荡数据。
计算脑震荡发生率和 95%置信区间（CI）以及分布情况。
在 2008/09 学年至 2016/17 学年期间，男生冰球共报告了 348 例脑震荡，脑震荡发生率为 0.68/1000 AE（95%CI，0.61-0.75）。大多数脑震荡发生在比赛中（85.6%），特别是在第一节之后（所有比赛脑震荡的 72.1%）。在练习脑震荡中，大多数发生在练习的第一个小时后（60.0%）。大多数脑震荡是由球员接触（47.7%）和板/玻璃接触（31.9%）引起的。尽管 69.0%的脑震荡运动员症状在 7 天内缓解，但只有 14.1%在一周内恢复活动。
大多数脑震荡发生在第二节和第三节。可能需要采取预防策略来应对由于比赛强度增加和疲劳增加导致的脑震荡风险增加。此外，运动员可能会从专注于预测比赛中冲击的预防措施中受益。
