Return-to-play protocols describe stepwise, graduated recoveries for safe return from concussion; however, studies that comprehensively track return-to-play time are expensive to administer and heavily sampled from elite male contact-sport athletes.
To retrospectively assess probable recovery time for collegiate patients to return to play after concussion, especially for understudied populations, such as women and nonelite athletes.
Cohort study; Level of evidence, 3.
Medical staff at a military academy logged a total of 512 concussion medical records over 38 months. Of these, 414 records included complete return-to-play protocols with return-to-play time, sex, athletic status, cause, and other data.
Overall mean return to play was 29.4 days. Sex and athletic status both affected return-to-play time. Men showed significantly shorter return to play than women, taking 24.7 days (SEM, 1.5 days) versus 35.5 days (SEM, 2.7 days) ( < .001). Intercollegiate athletes also reported quicker return-to-play times than nonintercollegiate athletes: 25.4 days (SEM, 2.6 days) versus 34.7 days (SEM, 1.6 days) ( = .002). These variables did not significantly interact.
Mean recovery time across all groups (29.4 days) showed considerably longer return to play than the most commonly cited concussion recovery time window (7-10 days) for collegiate athletes. Understudied groups, such as women and nonelite athletes, demonstrated notably longer recovery times. The diversity of this sample population was associated with longer return-to-play times; it is unclear how other population-specific factors may have contributed. These inclusive return-to-play windows may indicate longer recovery times outside the population of elite athletes.
复出参赛方案描述了从脑震荡中安全复出的逐步、分级恢复过程;然而,全面追踪复出参赛时间的研究实施成本高昂,且主要以精英男性接触性运动项目运动员为样本。
回顾性评估大学患者脑震荡后恢复参赛的可能时间,尤其是针对研究较少的人群,如女性和非精英运动员。
队列研究;证据等级,3级。
一所军事学院的医务人员在38个月内共记录了512份脑震荡医疗记录。其中,414份记录包含完整的复出参赛方案以及复出参赛时间、性别、运动状态、病因和其他数据。
总体平均复出参赛时间为29.4天。性别和运动状态均对复出参赛时间有影响。男性的复出参赛时间显著短于女性,分别为24.7天(标准误,1.5天)和35.5天(标准误,2.7天)(P<0.001)。校际运动员的复出参赛时间也比非校际运动员更快:25.4天(标准误,2.6天)和34.7天(标准误,1.6天)(P = 0.002)。这些变量之间没有显著的交互作用。
所有组的平均恢复时间(29.4天)显示,与大学运动员最常引用的脑震荡恢复时间窗口(7 - 10天)相比,复出参赛时间要长得多。研究较少的群体,如女性和非精英运动员,恢复时间明显更长。该样本人群的多样性与更长的复出参赛时间相关;尚不清楚其他特定人群因素可能产生了怎样的影响。这些更宽泛的复出参赛时间窗口可能表明精英运动员群体之外的恢复时间更长。
