Abstract

Background: Traumatic brain injury (TBI) in combat sports is relatively common, and rotational acceleration (RA) is a strong biomechanical predictor of TBI. This review summarizes RA values generated from head impacts in combat sport and puts them in the context of present evidence regarding TBI thresholds.

Sources of data: PubMed, EMBASE, Web of Science, Cochrane Library and Scopus were searched from inception to 31st December 2021. Twenty-two studies presenting RA data from head impacts across boxing, taekwondo, judo, wrestling and MMA were included. The AXIS tool was used to assess the quality of studies.

Areas of agreement: RA was greater following direct head strikes compared to being thrown or taken down. RA from throws and takedowns was mostly below reported injury thresholds. Injury thresholds must not be used in the absence of clinical assessment when TBI is suspected. Athletes displaying signs or symptoms of TBI must be removed from play and medically evaluated immediately.

Areas of controversy: Methodological heterogeneity made it difficult to develop sport-specific conclusions. The role of headgear in certain striking sports remains contentious.

Growing points: RA can be used to suggest and assess the effect of safety changes in combat sports. Gradual loading of training activities based on RA may be considered when planning sessions. Governing bodies must continue to work to minimize RA generated from head impacts.

Areas timely for developing research: Prospective research collecting real-time RA data is required to further understanding of TBI in combat sports.

旋转头部加速度和创伤性脑损伤在格斗运动:系统回顾。

背景:外伤性脑损伤(TBI)在格斗运动中比较常见，旋转加速度(RA)是TBI的一个强有力的生物力学预测指标。这篇综述总结了格斗运动中头部撞击产生的RA值，并将它们置于目前关于脑外伤阈值的证据背景下。数据来源:PubMed, EMBASE, Web of Science, Cochrane Library和Scopus从成立到2021年12月31日进行检索。包括22项研究，其中包括拳击、跆拳道、柔道、摔跤和综合格斗中头部撞击的RA数据。使用AXIS工具评估研究的质量。一致的地方:与被扔或被打倒相比，直接头部撞击后RA更大。投掷和起落的RA大多低于报道的受伤阈值。当怀疑有TBI时，在没有临床评估的情况下，不得使用损伤阈值。出现创伤性脑损伤迹象或症状的运动员必须立即离场并进行医学评估。争议领域:方法的异质性使得很难得出特定运动的结论。在某些引人注目的运动中，头饰的作用仍然存在争议。生长点:RA可用于建议和评估格斗运动中安全变化的效果。在计划课程时，可以考虑基于RA的逐步加载培训活动。管理机构必须继续努力，尽量减少头部撞击产生的类风湿关节炎。及时开展研究的领域:需要前瞻性研究收集实时RA数据，以进一步了解搏击运动中的TBI。
