The purpose of this study was to (1) examine the diagnostic utility of the King-Devick (KD) in professional ice hockey players and (2) determine whether the KD provides unique variance in predicting a diagnosis of concussion when given in combination with the SCAT-5.
Cohort Study.
Primary care.
PATIENTS/PARTICIPANTS: Professional ice hockey players.
Diagnosis versus no diagnosis of concussion.
King-Devick and SCAT-5 component scores.
In part 1, players suspected of having a concussion were evaluated at baseline and acutely with the KD and either the SCAT-3 or the SCAT-5. Players evaluated and not diagnosed with concussion served as active controls. In part 2, a separate group of players suspected of having a concussion was evaluated acutely with both the KD and SCAT-5.
In part 1 of this study, 53 concussed players declined in performance on the KD from baseline to acute evaluation, whereas the performance of 76 active controls improved significantly. In part 2 of the study, 75 players were diagnosed with concussion and compared with 80 active controls who were evaluated and not diagnosed with concussion. Concussed players revealed a decline in KD performance from baseline to acute evaluation when compared with controls. However, the KD did not account for significant unique variance in predicting a diagnosis of concussion after accounting for SCAT-5 data.
The KD is useful in differentiating concussed and not concussed athletes acutely, but the KD does not seem to add additional diagnostic value over and above the SCAT-5.
本研究的目的是（1）检验King-Devick（KD）测试在职业冰球运动员中的诊断效用，以及（2）确定在与SCAT-5联合使用时，KD测试在预测脑震荡诊断方面是否能提供独特的变量信息。

患者/参与者：职业冰球运动员。
脑震荡诊断与否。
King-Devick测试和SCAT-5各部分得分。
在第一部分中，对疑似脑震荡的运动员在基线期和急性期进行KD测试，同时使用SCAT-3或SCAT-5进行评估。接受评估但未被诊断为脑震荡的运动员作为对照。在第二部分中，对另一组疑似脑震荡的运动员在急性期同时进行KD测试和SCAT-5评估。
在本研究第一部分中，53名脑震荡运动员的KD测试表现从基线期到急性期评估有所下降，而76名对照运动员的表现显著改善。在研究的第二部分中，75名运动员被诊断为脑震荡，并与80名接受评估但未被诊断为脑震荡的对照运动员进行比较。与对照相比，脑震荡运动员从基线期到急性期评估时KD测试表现下降。然而，在纳入SCAT-5数据后，KD测试在预测脑震荡诊断方面并未显示出显著的独特变量信息。
KD测试在急性区分脑震荡和未患脑震荡运动员方面是有用的，但KD测试似乎并未在SCAT-5之外增加额外的诊断价值。
