This study undertook to use the K-D sideline test with the SCAT2 to see if concussions could be identified in amateur rugby league players over a representative competition period.
A prospective cohort study was conducted on two teams participating in an amateur rugby league. All players were tested for signs of concussion utilising the K-D test and players with longer times than their baseline scores undertook a further concussion assessment with the SCAT2.
Five athletes with suspected concussion were evaluated by K-D testing. Three concussions were associated with witnessed events during the matches and two athletes were identified by the team medic as having longer K-D time scores incidentally post-match compared to baseline. Post-match K-D scores for all concussed athletes were worse than baseline for those with reported or witnessed concussion events (7s; 5.0-7.1; p=0.025) and for those identified incidentally (>5s; 8.9-9.1s). Both groups also reported more symptoms on the PCSS (a part of the SCAT2) post-match.
In this rugby cohort, the K-D test was not only useful in identifying changes in players with witnessed head trauma, but in identifying changes in players with an un-witnessed suspected concussion.
本研究采用 K-D 侧线测试和 SCAT2，观察在代表性比赛期间是否能识别业余英式橄榄球联赛球员的脑震荡。
对参加业余英式橄榄球比赛的两支队伍进行前瞻性队列研究。所有球员均接受 K-D 测试，以确定是否有脑震荡迹象。对于得分超过基线的球员，采用 SCAT2 进行进一步的脑震荡评估。
对 5 名疑似脑震荡的运动员进行了 K-D 测试评估。其中 3 例与比赛中的目击事件有关，另外 2 例运动员在赛后与基线相比，由队医发现 K-D 时间得分延长。与报告或目击的脑震荡事件（7 秒；5.0-7.1；p=0.025）相比，所有脑震荡运动员的赛后 K-D 得分均比基线差，并且与意外发现的（>5 秒；8.9-9.1 秒）得分相比也更差。这两组在赛后的 PCSS（SCAT2 的一部分）上也报告了更多的症状。
在这个英式橄榄球队列中，K-D 测试不仅有助于识别有目击头部创伤的运动员的变化，还能识别无目击疑似脑震荡的运动员的变化。
