运动脑震荡评估工具(SCAT)是运动相关脑震荡(SRC)之后使用最广泛的工具。最初的SCAT症状负担是大学运动员康复的有力预测指标;然而,在SRC后的急性期(<48小时)内,症状表现是否有变化尚不清楚。这项队列研究的目的是检查美国大学体育协会(NCAA)运动员的急性SRC症状表现。来自美国30所大学的脑震荡NCAA大学运动员(n=1,780)参加了脑震荡评估,Research,包括教育(CARE)联盟。记录损伤发生时间和SCAT给药数据,从哪个时间到SCAT(小时,连续)进行计算。主要结果是SCAT总症状严重程度[(TSS),0-126].使用多变量负二项回归来检查自损伤以来的时间(小时)与TSS之间的关联。协变量包括性别,之前的脑震荡,运动接触水平,失忆/失去知觉,立即报告受伤情况,和受伤情况。随机效应(人水平)占多重评估。提供了TSS评分比(SR)和相关的95%置信区间(CI)。SCAT在SRC后平均14小时(第25-75百分位数:1.2-24小时),所有参与者的平均TSS为27.35±21.28。调整协变量效应后,SCAT时间与TSS下降1%相关(SR:0.99,95%CI:0.99-0.99,p<0.001)。总的来说,我们观察到一个小的,但SRC后每小时TSS显著下降。在急性期评估一次脑震荡的运动员可能会提供足够的症状幸福感,因为措施没有剧烈波动。未来的研究应旨在研究急性症状演变如何影响恢复指标。
The Sport Concussion Assessment Tool (SCAT) is the most widely used tool following sport-related concussion (SRC). Initial SCAT symptom burden is a strong predictor of recovery in collegiate athletes; however, it is unknown if symptom presentation varies within the acute (<48 hours) post-SRC phase. The purpose of this cohort study was to examine acute SRC symptom presentation among National Collegiate Athletic Association (NCAA) athletes. Concussed NCAA varsity athletes (n=1,780) from thirty universities across the United States that participated in the Concussion Assessment, Research, and Education (CARE) Consortium were included. Time of injury occurrence and SCAT administration data were recorded, from which time-to-SCAT (hours, continuous) was calculated. The main outcome was SCAT total symptom severity [(TSS), 0-126]. Multivariable negative binomial regression was used to examine the association between time (hours) since injury and TSS. Covariates included sex, previous concussion, sport contact level, amnesia/loss of consciousness, immediate reporting of injury, and injury situation. A random effect (person level) accounted for multiple assessments. TSS score ratios (SR) with associated 95% confidence intervals (CI) were provided. The SCAT was administered an average of 14 (25th-75th percentile: 1.2-24) hours post-SRC, and average TSS was 27.35±21.28 across all participants. Time-to-SCAT was associated with a 1% decrease in TSS after adjusting for covariate effects (SR: 0.99, 95% CI: 0.99-0.99, p<0.001). Overall, we observed a small, but significant decrease in TSS with each hour post-SRC. Assessing a concussed athlete once in the acute phase will likely provide a sufficient sense of their symptomatic well-being, as measures did not fluctuate dramatically. Future research should aim to examine how acute symptom evolution influences recovery metrics.
