摘要

背景:体位不稳是脑震荡后常见的观察结果,平衡评估在临床评估中起着至关重要的作用。目前广泛应用的脑震荡后平衡测试主要侧重于静态和动态平衡,而忽略了反应性平衡的关键方面。目的:研究脑震荡对大学生运动员反应性平衡的急性和纵向影响。方法:在赛季前基线和4个脑震荡后时间点(急性期、RTP前、RTP后和脑震荡后6个月)对脑震荡和健康匹配的NCAA一级运动员进行评估。仪器改进的推和释放测试测量了单任务和双任务条件下的反应平衡。应用广义估计方程研究了脑震荡对稳定时间和阶跃潜伏期的纵向影响。结果:脑震荡后,运动员在双任务条件下表现出反应性平衡受损,表现为更长的稳定时间(P = 0.004)。这些急性损伤是短暂的,并随时间恢复。探索性分析显示,运动员一生中第一次脑震荡表现为急性(P = 0.037)和纵向(P = 0.037)。与没有终身脑震荡的对照组相比,在单任务和双任务中有损伤。结论:这项综合评估为脑震荡后损伤的多面性提供了见解,并强调了在评估运动员平衡时考虑认知需求和脑震荡史的重要性。

Acute and Longitudinal Effects of Concussion on Reactive Balance in Collegiate Athletes.

BackgroundPostural instability is a common observation after concussions, with balance assessments playing a crucial role in clinical evaluations. Widely used post-concussion balance tests focus primarily on static and dynamic balance, excluding the critical aspect of reactive balance.ObjectivesThis study investigated the acute and longitudinal effects of concussion on reactive balance in collegiate athletes.MethodsConcussed and healthy matched controls NCAA division I athletes were assessed at pre-season baseline and 4 post-concussion timepoints: acute, pre-return-to-play (RTP), post-RTP, and 6 months post-concussion. The instrumented-modified Push and Release test measured reactive balance during single- and dual-task conditions. Longitudinal effects of concussions on time to stability and step latency metrics were investigated applying Generalized Estimating Equations.ResultsAcutely after concussion, athletes demonstrated impaired reactive balance, indicated by longer times to stability, in dual-task conditions (P = .004). These acute impairments were transient and recovered over time. Exploratory analyses revealed that athletes who sustained their first lifetime concussion exhibited both acute (P = .037) and longitudinal (P = .004 at post-RTP) impairments in single- and dual-task compared to controls with no lifetime concussion.ConclusionsThis comprehensive evaluation provides insights into the multifaceted nature of post-concussion impairments and emphasizes the importance of considering cognitive demand and history of concussions in assessing athletes' balance.
