With the heightened awareness of concussions in all sports, the development and implementation of effective prevention strategies are necessary. Education has been advocated as an effective injury prevention intervention.
To examine the effectiveness of the 'Smart Hockey: More Safety, More Fun' video on knowledge transfer among minor league hockey players.
Cluster-randomised controlled trial.
A total of 267 participants from two age divisions and competitive levels were assigned to either a video or no-video group. The video was shown (or not shown) to the entire team as a result of random assignment. To evaluate the effectiveness of the educational video, questionnaires specific to concussion knowledge and players' attitudes and behaviours were completed.
There was a significant increase in the players' concussion knowledge scores immediately following exposure to the video (F(1,103)=27.00, p<0.001). However, concussion knowledge at 2 months was not significantly different between the video and no-video groups, after controlling for prior knowledge level, age and competitive level (F(1,115)=0.41, p=0.523). Similarly, players' attitudes and behaviour scores at 2 months did not differ between groups (F(1,115)=0.41, p=0.507).
We were able to show that a single viewing of an educational video in hockey could immediately improve knowledge about concussion but that this effect was transient and lost at 2-month follow-up. Future prevention endeavours in hockey and other sports should attempt to incorporate strategies and modalities to enhance knowledge retention.
随着人们对所有运动中脑震荡的认识不断提高，有必要制定和实施有效的预防策略。教育已被提倡为一种有效的伤害预防干预措施。
检验“智能曲棍球：更安全，更有趣”视频在青少年曲棍球运动员知识转移方面的效果。
群组随机对照试验。
将来自两个年龄组和竞技水平的 267 名参与者分配到视频组或无视频组。视频作为随机分配的结果显示（或不显示）给整个团队。为了评估教育视频的有效性，专门设计了与脑震荡知识以及球员态度和行为相关的问卷进行评估。
在接触视频后，球员的脑震荡知识得分立即显著增加（F(1,103)=27.00，p<0.001）。然而，在控制先前知识水平、年龄和竞技水平后，视频组和无视频组在 2 个月时的脑震荡知识得分没有显著差异（F(1,115)=0.41，p=0.523）。同样，在 2 个月时，两组球员的态度和行为得分没有差异（F(1,115)=0.41，p=0.507）。
我们能够表明，在曲棍球中单次观看教育视频可以立即提高对脑震荡的认识，但这种效果是短暂的，在 2 个月的随访中消失。未来在曲棍球和其他运动中的预防工作应该尝试采用策略和方式来增强知识的保留。
