目标:与立即报告的运动员相比,脑震荡后继续比赛可能导致更差的结果和更长的恢复时间。这在青年运动员中得到了很好的证明,尽管在医疗保健方面存在差异,但对大学运动员的关注较少,恢复轨迹,和额外的压力。因此,这项研究的目的是确定脑震荡后立即继续比赛是否会影响大学运动员的临床结局和恢复时间.
方法:前瞻性,重复测量设计用于比较继续比赛的大学运动员(n=37)和脑震荡后立即移除的运动员(n=56)的临床结局和恢复时间.使用运动脑震荡评估工具第5版(SCAT5)在脑震荡后5天内和完全医疗许可(FMC;±3天)进行评估,前庭/眼部运动筛查评估,和高级移动性评估工具。Mann-WhitneyU检验确定了组间临床结果的差异。Cox比例风险回归模型检查了与症状缓解天数和FMC天数相关的因素之间的关系。和协变量是根据以前的文献先验选择的。报告每个预测变量的95%CI的危险比。
结果:在急性访视和FMC访视的近收敛点平均距离(cm;p=0.005)之间,发现SCAT5浓度综合评分(p=0.010)和SCAT5延迟回忆综合评分(p=0.045)存在显着差异。两组在症状缓解天数上没有差异(10天vs7天,p=0.05)和清除天数(13vs11.50天,p=0.13)。组间与症状缓解天数的关联(χ2[4]=5.052,p=0.282),和清除天数(χ2[4]=3.624,p=0.459)在校正协变量时没有显著性。
结论:与立即被移除的运动员相比,脑震荡后继续比赛的大学运动员没有表现出更差的临床结果或恢复时间。虽然在这项研究中发现的缺乏差异可以得到先前文献的支持,包括改善教育,意识,报告态度,以及近年来大学层面的脑震荡管理,作者认为,差异更有可能是由于研究特定的差异(例如,样本量,护理设置,和时间安排)。因此,这些发现不应减少继续比赛的危险以及脑震荡后及时清除的重要性。
OBJECTIVE: Continued play following concussion can lead to worse outcomes and longer recoveries compared with athletes who immediately report. This has been well documented in youth athletes, while less attention has been paid to collegiate athletes despite differences in healthcare access, recovery trajectories, and additional pressures to play. Therefore, the purpose of this study was to determine if continuing to play immediately following a concussion influenced clinical outcomes and recovery time in collegiate athletes.
METHODS: A prospective, repeated-measures design was used to compare clinical outcomes and recovery time between collegiate athletes who continued playing (n = 37) and those immediately removed (n = 56) after a concussion. Assessments were conducted within 5 days of the concussion and at full medical clearance (FMC; ± 3 days) using the Sport Concussion Assessment Tool-5th edition (SCAT5), Vestibular/Ocular Motor Screening assessment, and High-Level Mobility Assessment Tool. Mann-Whitney U-tests determined differences in clinical outcomes between groups. Cox proportional hazards regression models examined the relationship between factors associated with days to symptom resolution and days to FMC, and covariates were selected a priori based on previous literature. Hazard ratios with 95% CIs were reported for each predictor variable.
RESULTS: Significant differences were found in SCAT5 concentration composite scores (p = 0.010) and SCAT5 delayed recall composite scores (p = 0.045) at the acute visit and near point of convergence average distance (cm; p = 0.005) at the FMC visit between the group who continued to play and those who were immediately removed. There were no differences between groups in days to symptom resolution (10 vs 7 days, p = 0.05) and days to clearance (13 vs 11.50 days, p = 0.13). The association between groups and days to symptom resolution (χ2[4] = 5.052, p = 0.282), and days to clearance (χ2[4] = 3.624, p = 0.459) were not significant when adjusting for covariates.
CONCLUSIONS: Collegiate athletes who continued to play following concussion did not exhibit worse clinical outcomes or recovery times compared with athletes who were immediately removed. While the lack of differences found in this study could be supported by prior literature, including improved education, awareness, reporting attitudes, and concussion management at the collegiate level in recent years, the authors believe discrepancies are more likely due to study-specific differences (e.g., sample size, care setting, and timing). Therefore, these findings should not diminish the dangers of continued play and the importance of timely removal after concussion.
