Musculoskeletal injuries and insufficient sleep are common among U.S. Army Rangers. There has been limited research into whether indices of sleep differ between injured and uninjured Rangers. The purpose of this study was to investigate the association between self-reported sleep and musculoskeletal injury in Rangers.
A total of 82 Army Rangers (male, 25.4 ± 4.0 years) were asked if they currently have any musculoskeletal injuries; completed the Pittsburgh Sleep Quality Index (PSQI), the Insomnia Severity Index (ISI), and the Stanford Sleepiness Scale; and were asked about their average sleep quality/sleep duration over the preceding week. Rangers were then dichotomized into groups, one that reported a current musculoskeletal injury and another that did not.
The reported musculoskeletal injury prevalence was 15.9% (n = 13). The Rangers that reported an injury, compared to those that did not, had a significantly higher Global PSQI score (6.7 ± 3.7 versus 4.5 ± 2.7, P = .012) and ISI score (10.9 ± 3.7 versus 7.2 ± 4.1, P = .003), both indicative of poorer sleep. The group reporting an injury rated their average sleep quality over the preceding week significantly lower compared to those that did not report an injury (50.8 ± 17.5 versus 68.9 ± 18.3, P = .001). There was no significant group difference in the average nightly sleep duration (6.1 ± 1.0 hours versus 6.5 ± 0.9 hours, P = .099).
In this cohort of male Army Rangers, In this cohort of male Army Rangers, those with a musculoskeletal injury reported poorer sleep quality than uninjured Rangers. Sleep duration was not associated with reported injuries; however, both the injured group and uninjured group averaged less than the recommended amounts of sleep. Further investigation into the relationship between musculoskeletal injury and sleep in military personnel is warranted.
肌肉骨骼损伤和睡眠不足在美国陆军游骑兵中很常见。关于受伤和未受伤的游骑兵之间睡眠指标是否存在差异的研究有限。本研究的目的是调查游骑兵自我报告的睡眠与肌肉骨骼损伤之间的关联。
共82名陆军游骑兵（男性，25.4±4.0岁）被询问他们目前是否有任何肌肉骨骼损伤；完成匹兹堡睡眠质量指数（PSQI）、失眠严重程度指数（ISI）和斯坦福嗜睡量表；并被问及他们前一周的平均睡眠质量/睡眠时间。然后将游骑兵分为两组，一组报告目前有肌肉骨骼损伤，另一组没有。
报告的肌肉骨骼损伤患病率为15.9%（n = 13）。与未受伤的游骑兵相比，报告受伤的游骑兵的PSQI总分显著更高（6.7±3.7对4.5±2.7，P = 0.012），ISI得分也显著更高（10.9±3.7对7.2±4.1，P = 0.003），两者均表明睡眠较差。与未报告受伤的游骑兵相比，报告受伤的组对其前一周的平均睡眠质量评分显著更低（50.8±17.5对68.9±18.3，P = 0.001）。两组的平均夜间睡眠时间没有显著差异（6.1±1.0小时对6.5±0.9小时，P = 0.099）。
在这一男性陆军游骑兵队列中，有肌肉骨骼损伤的人报告的睡眠质量比未受伤的游骑兵差。睡眠时间与报告的损伤无关；然而，受伤组和未受伤组的平均睡眠时间均低于推荐量。有必要进一步研究军事人员肌肉骨骼损伤与睡眠之间的关系。
