To investigate the use of the King-Devick (K-D) test for sideline assessment of concussive injuries in a New Zealand amateur women's rugby union team.
Prospective cohort observational.
All players were K-D tested during pre-season using a tablet (iPad; Apple Inc., Cupertino, CA). Differences in K-D scores and test-retest reliability were calculated for baseline test scores, baseline, and post-injury (concussion) sideline assessment and baseline and post-season testing scores for tests by year and as a combined score.
One training-related (0.3 per 1000 training-hrs) and nine match-related (16.1 per 1000 match-hrs) concussions were recorded. The K-D post-injury (concussion) sideline test score were significantly slower than established baseline (-4.4 [-5.8 to -3.4] s; χ = 42.2; p < 0.0001; t = -4.0; p = 0.0029; d = -0.8). There was good-to-excellent reliability of the K-D test for baseline (ICC: 0.84 to 0.89), post-injury (concussion) sideline assessment (ICC: 0.82 to 0.97) and post-season evaluation (ICC: 0.79 to 0.83).
By utilising the baseline to post-injury (concussion) assessment comparisons, any player with a post-injury (concussion) assessment slowing of their K-D test time, regardless of whether the player has, or has not had a witnessed insult, should be withheld from any further participation until they are evaluated by a medical professional trained in the management of concussion.
This study has provided additional evidence to support the use of the K-D test as a frontline method of assessing concussion with good to excellent reliability of the test for baseline, side-line assessment and post-season evaluation.
调查在新西兰一支业余女子橄榄球联盟球队中使用King-Devick（K-D）测试进行脑震荡损伤的场边评估情况。
前瞻性队列观察研究。
在季前赛期间，使用平板电脑（iPad；苹果公司，库比蒂诺，加利福尼亚州）对所有球员进行K-D测试。计算K-D得分的差异以及重测信度，用于基线测试得分、基线、损伤后（脑震荡）场边评估以及按年份和综合得分计算的基线与赛季后测试得分。
记录到1次与训练相关的脑震荡（每1000训练小时0.3次）和9次与比赛相关的脑震荡（每1000比赛小时16.1次）。损伤后（脑震荡）场边测试的K-D得分显著慢于既定基线（-4.4 [-5.8至-3.4]秒；χ = 42.2；p < 0.0001；t = -4.0；p = 0.0029；d = -0.8）。K-D测试在基线（组内相关系数：0.84至0.89）、损伤后（脑震荡）场边评估（组内相关系数：0.82至0.97）和赛季后评估（组内相关系数：0.79至0.83）方面具有良好至优秀的信度。
通过利用基线至损伤后（脑震荡）评估的比较，任何损伤后（脑震荡）评估时K-D测试时间减慢的球员，无论该球员是否有或没有目睹的受伤情况，在由受过脑震荡管理培训的医疗专业人员评估之前，都应禁止其进一步参与比赛。
本研究提供了额外证据，支持使用K-D测试作为评估脑震荡的一线方法，该测试在基线、场边评估和赛季后评估方面具有良好至优秀的信度。
