To determine whether the King-Devick (K-D) test used as a sideline test in junior rugby league players over 12 matches in a domestic competition season could identify witnessed and incidentally identified episodes of concussion.
A prospective observational cohort study of a club level junior rugby league team (n=19) during the 2014 New Zealand competition season involved every player completing two pre-competition season baseline trials of the K-D test. Players removed from match participation, or who reported any signs or symptoms of concussion were assessed on the sideline with the K-D test and referred for further medical assessment. Players with a pre- to post-match K-D test difference >3s were referred for physician evaluation.
The baseline test-retest reliability of the K-D test was high (rs=0.86; p<0.0001). Seven concussions were medically identified in six players who recorded pre- to post-match K-D test times greater than 3s (mean change of 7.4s). Post-season testing of players demonstrated improvement of K-D time scores consistent with learning effects of using the K-D test (67.7s vs. 62.2s).
Although no witnessed concussions occurred during rugby play, six players recorded pre- to post-match changes with a mean delay of 4s resulting in seven concussions being subsequently confirmed post-match by health practitioners. All players were medically managed for a return to sports participation.
The K-D test was quickly and easily administered making it a practical sideline tool as part of the continuum of concussion assessment tools for junior rugby league players.
确定在国内比赛赛季的12场比赛中，将King-Devick（K-D）测试用作青少年橄榄球联盟球员的场边测试，是否能够识别出有记录的和偶然发现的脑震荡事件。
对一支俱乐部级别的青少年橄榄球联盟球队（n = 19）在2014年新西兰比赛赛季进行前瞻性观察队列研究，每位球员在赛季前完成两次K-D测试的基线试验。被禁止参加比赛的球员，或报告有任何脑震荡迹象或症状的球员，在场边接受K-D测试评估，并被转介进行进一步的医学评估。比赛前后K-D测试差异>3秒的球员被转介给医生进行评估。
K-D测试的基线重测信度很高（rs = 0.86；p<0.0001）。在6名球员中通过医学鉴定发现了7次脑震荡，这些球员比赛前后的K-D测试时间大于3秒（平均变化7.4秒）。球员的赛季后测试表明，K-D时间得分有所改善，这与使用K-D测试的学习效果一致（67.7秒对62.2秒）。
虽然在橄榄球比赛期间没有发生有记录的脑震荡，但6名球员记录了比赛前后的变化，平均延迟4秒，随后有7次脑震荡在赛后被健康从业者确认。所有球员都接受了医学管理以恢复运动参与。
K-D测试实施快速简便，使其成为青少年橄榄球联盟球员脑震荡评估工具连续统一体的实用场边工具。
