To explore the potential utility of head acceleration event (HAE) measurements to augment identification of players for further concussion screening in non-helmeted contact sport.
Prospective observational pilot study.
210 (118 female) professional Australian football players in 2017 season.
Players wore the X-Patch® accelerometer for one match each with data collected across 14 matches. Players with HAEs above thresholds associated with concussion, 95 g (males) or 85.5 g (females), were compared to players identified to have suspected concussion by club personnel during the inspected matches. Video review of matches was undertaken by a physician blinded to HAEs to identify players with concussive signs.
Among 26 players (50% female) with HAEs above threshold, two players were screened for concussion. Of the remaining 24 players, nine were not visible on video at the HAE time, six sustained verifiable head impacts, and nine sustained verifiable body impacts with no head impacts. Among 184 players with HAEs below threshold, five players were screened.
Players were identified to have head impacts and suspected concussion in the absence of HAEs above threshold. Use of X-Patch® was not sufficiently reliable for identifying players for further concussion screening in professional Australian football. Video review of head impacts remains essential in concussion screening.
探讨头部加速度事件 (HAE) 测量在非头盔接触性运动中进一步识别疑似脑震荡运动员以进行筛选的潜在作用。
前瞻性观察性试点研究。
2017 赛季 210 名（女性 118 名）澳大利亚职业足球运动员。
运动员佩戴 X-Patch®加速度计参加每场比赛，共收集了 14 场比赛的数据。将 HAE 超过与脑震荡相关的阈值（男性 95g，女性 85.5g）的运动员与在检查比赛中由俱乐部人员确定疑似脑震荡的运动员进行比较。由一名对 HAE 不知情的医生对比赛进行视频复查，以识别有脑震荡体征的运动员。
在 HAE 超过阈值的 26 名运动员中（50%为女性），有 2 名运动员接受了脑震荡筛查。在其余 24 名运动员中，9 名运动员在 HAE 时间点无法在视频中看到，6 名运动员遭受了可验证的头部撞击，9 名运动员遭受了可验证的身体撞击但没有头部撞击。在 HAE 低于阈值的 184 名运动员中，有 5 名运动员接受了筛查。
在 HAE 未超过阈值的情况下，运动员仍被识别出有头部撞击和疑似脑震荡。X-Patch® 的使用在识别疑似脑震荡运动员以进行进一步筛查方面的可靠性还不够。对头部撞击的视频复查仍然是脑震荡筛查的必要手段。
