To investigate changes from baseline on SCAT3 as a result of football game exposure, and association with X2 Patch measured head acceleration events in amateur Australian footballers.
Prospective cohort.
Peak linear acceleration (PLA) of the head (>10 g) was measured by wearable head acceleration sensor X2 Biosystems X-Patch in male (n=34) and female (n=19) Australian footballers. SCAT3 was administered at baseline (B) and post-game (PG).
1394 head acceleration events (HEA) >10 g were measured. Mean and median HEA PLA were recorded as 15.2 g (SD=9.2, range=10.0-115.8) and 12.4 g (IQR=11.0-15.6) respectively. No significant difference in median HEA PLA (g) was detected across gender (p=0.55), however, more HEAs were recorded in males (p=0.03). A greater number (p=0.004) and severity (p<0.001) of symptoms were reported PG than at B. No significant association between number of HEA or median PLA, and SCAT3 change scores (p>0.05 for all), was identified for either gender.
Increase in symptom severity post game was not associated with X2 measured HEA. Males sustained more HEA, however HEA PLA magnitude did not differ across gender. Further work on the validation of head acceleration sensors is required and their role in sports concussion research and medical management.
研究足球比赛暴露对 SCAT3 的影响，并探讨其与 X2 贴片测量的业余澳大利亚足球运动员头部加速度事件的相关性。
前瞻性队列研究。
使用可穿戴头部加速度传感器 X2 Biosystems X-Patch 测量男性（n=34）和女性（n=19）澳大利亚足球运动员头部的峰值线性加速度（PLA）（>10 g）。在基线（B）和赛后（PG）时进行 SCAT3 测试。
共测量了 1394 个>10 g 的头部加速度事件（HEA）。记录的平均和中位数 HEA PLA 分别为 15.2 g（SD=9.2，范围为 10.0-115.8）和 12.4 g（IQR=11.0-15.6）。性别之间的中位数 HEA PLA（g）无显著差异（p=0.55），但男性记录的 HEA 更多（p=0.03）。与基线相比，赛后报告的症状数量（p=0.004）和严重程度（p<0.001）更高。无论是男性还是女性，HEA 数量或中位数 PLA 与 SCAT3 变化评分之间均无显著相关性（p>0.05）。
赛后症状严重程度的增加与 X2 测量的 HEA 无关。男性承受了更多的 HEA，但男女之间的 HEA PLA 幅度没有差异。需要进一步研究头部加速度传感器的验证及其在运动性脑震荡研究和医疗管理中的作用。
