OBJECTIVE 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. DESIGN Prospective cohort observational. METHODS 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. RESULTS 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; χ2(1) = 42.2; p < 0.0001; t(9) = -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). DISCUSSION 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. CONCLUSION 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.

使用 King-Devick 测试在新西兰两个赛季的国内业余女子橄榄球联盟团队中识别脑震荡

目的 调查使用 King-Devick (KD) 测试对新西兰业余女子橄榄球队的脑震荡损伤进行边线评估。设计 前瞻性队列观察。方法 所有球员都在季前赛期间使用平板电脑（iPad；苹果公司，加利福尼亚州库比蒂诺）进行了 KD 测试。KD 分数和重测信度的差异是针对基线测试分数、基线和受伤后（脑震荡）边线评估以及基线和季后测试分数按年份和作为组合分数计算的。结果 记录了 1 次与训练相关的脑震荡（每 1000 次培训小时 0.3 次）和 9 次与比赛相关的脑震荡（每 1000 次比赛小时 16.1 次）。KD 伤后（脑震荡）边线测试得分明显低于既定基线（-4.4 [-5.8 至 -3.4] s；χ2(1) = 42.2；p < 0.0001；t(9) = -4.0；p = 0.0029；d = -0.8）。KD 测试对于基线（ICC：0.84 至 0.89）、伤后（脑震荡）边线评估（ICC：0.82 至 0.97）和季后评估（ICC：0.79 至 0.83）具有良好至极好的可靠性。讨论 通过使用基线与伤后（脑震荡）评估比较，任何受伤后（脑震荡）评估减慢 KD 测试时间的球员，无论该球员是否有或没有目睹过侮辱，都应该在接受脑震荡管理培训的医疗专业人员进行评估之前，不得进一步参与。结论 本研究提供了额外的证据来支持使用 KD 测试作为评估脑震荡的一线方法，具有良好到极好的基线测试可靠性，
