To evaluate how an exertional field-test impacts the Sport Concussion Assessment Tool 5 (SCAT5) subcomponents in uninjured athletes.
Prospective case-series.
Sports medicine setting.
A total of 37 rugby and wrestling athletes (76% female) with a median age of 19 years (range: 18-23). Twenty-one (57%) had a history of concussion.
The SCAT5 was administered prior-to and following a volitionally fatiguing, field-based 30-15 Intermittent Fitness Test. The primary outcome measures included: total symptom scores and severity, standardized assessment of concussion, neurological screening, and balance errors during the modified balance error scoring system. Wilcoxon signed-rank tests examined differences in ordinal data between pre- and post-exertion with Bonferroni corrections (alpha = 0.006). Data were also stratified into time to SCAT5 administration post-exertion and compared via Cliff's Delta (d).
The SCAT5 was administered a median of 20-min (interquartile range: 14-26-min) following exertion. No differences were found pre- and post-exertion across all SCAT5 metrics (p > 0.048). Within the post-exertion 0-10-min stratification, total symptoms and severity scores appeared to be elevated with a large effect size (d ≥ 0.64).
While SCAT5 metrics were not statistically altered when quantified a median of 20-min following high-intensity exertion; greater symptom reporting may occur 10-min following exertion.
评估一项运动性疲劳测试对未受伤运动员的运动性脑震荡评估工具 5 （SCAT5）分量表的影响。
前瞻性病例系列研究。
运动医学环境。
共有 37 名橄榄球和摔跤运动员（76%为女性），平均年龄 19 岁（范围：18-23 岁）。21 名（57%）有脑震荡病史。
在自愿性疲劳的基于现场的 30-15 间歇性体能测试之前和之后，对 SCAT5 进行了评估。主要观察指标包括：总症状评分和严重程度、标准化脑震荡评估、神经学筛查以及在改良平衡错误评分系统中的平衡错误。Wilcoxon 符号秩检验用于检验预疲劳和疲劳后之间的等级数据差异，并进行 Bonferroni 校正（α=0.006）。数据还按疲劳后进行 SCAT5 评估的时间进行分层，并通过 Cliff 的 Delta（d）进行比较。
在疲劳后，SCAT5 的中位数给药时间为 20 分钟（四分位距：14-26 分钟）。在所有 SCAT5 指标上，疲劳前后均未发现差异（p>0.048）。在疲劳后 0-10 分钟的分层中，总症状和严重程度评分似乎升高，具有较大的效应量（d≥0.64）。
尽管在高强度疲劳后平均 20 分钟进行量化时，SCAT5 指标没有统计学上的改变；但在疲劳后 10 分钟可能会出现更多的症状报告。
