To use the King-Devick (KD) test and Sports Concussion Assessment Tool 2 (SCAT2) in amateur rugby union players to identify witnessed and unrecognised episodes of concussion that occurred from match participation.
A prospective observational cohort study was conducted on a premier club level amateur rugby union team during the 2012 competition in New Zealand. Every player completed a pre-competition questionnaire on concussion history, a baseline PCSS and two trials of the KD before they participated in any match activities.
For players reporting a concussion in the previous three years there was an average of 4.0±2.8 concussions per player. There were 22 concussive incidents recorded over the duration of the competition (46 per 1000 match hours). Five concussive incidents were witnessed (11 per 1000 match hours) and 17 unrecognised concussive incidents were identified with the KD (37 per 1000 match hours). Witnessed concussions recorded, on average, a longer KD on the day of injury (5.5±2.4s) than unrecognised concussions (4.4±0.9s) when compared with their baseline KD.
The KD was able to identify players that had not shown, or reported, any signs or symptoms of a concussion but who had meaningful head injury. The current rate of concussion reported was a ten-fold increase in previously reported concussion injury rates. This makes the KD suitable for rapid assessment in a limited time frame on the sideline such as a five-minute window to assess and review suspected concussed players in rugby union.
使用 King-Devick（KD）测试和运动性脑震荡评估工具 2（SCAT2）来识别业余橄榄球联盟球员中因比赛参与而发生的有目击者和无目击者的脑震荡事件。
在新西兰 2012 年的比赛中，对一个一流俱乐部级别的业余橄榄球联盟队进行了前瞻性观察队列研究。每位球员在参加任何比赛活动之前，都完成了一份关于脑震荡史、基线 PCSS 和两次 KD 测试的预竞赛问卷。
在过去三年中报告有脑震荡的球员中，平均每个球员有 4.0±2.8 次脑震荡。在比赛期间记录了 22 次脑震荡事件（每 1000 比赛小时 46 次）。有 5 次脑震荡事件被目击（每 1000 比赛小时 11 次），17 次未被识别的脑震荡事件通过 KD 确定（每 1000 比赛小时 37 次）。与基线 KD 相比，被记录的目击脑震荡在受伤当天的 KD 值更长（5.5±2.4s），而未被识别的脑震荡则更短（4.4±0.9s）。
KD 能够识别出那些没有表现出或报告过任何脑震荡迹象或症状但头部受到了明显损伤的球员。目前报告的脑震荡发生率是以前报告的脑震荡损伤率的十倍。这使得 KD 适合在有限的时间内进行快速评估，例如在橄榄球比赛中，有 5 分钟的时间窗口来评估和审查疑似脑震荡的球员。
