Introduction: Increased risk of musculoskeletal (MSK) injury post-concussion has been reported in collegiate athletes, yet it is unknown if professional football athletes are at the same risk of secondary injury. The objective of this study was to determine if the risk of MSK injury in National Football League (NFL) athletes increases after concussion.
Methods: NFL injury reports from 2013 to 2017 were collected from public websites. Concussed athletes (n=91) were equally matched to a non-injured control and an athlete with an incident of musculoskeletal (MSK) injury.
Results: Following their return to sport, concussed athletes were 2.35 times more likely to have a subsequent MSK injury relative to non-injured controls (95% CI: 2.35 [1.25, 4.44], P = 0.01), but were no more likely than athletes with an incident MSK injury (P = 0.55). Likewise, athletes with an incident MSK injury were no more likely to have a subsequent MSK injury than controls (P = 0.08).
Discussion: Increased odds of MSK injury in the 12-week period following a concussion in professional football athletes warrants future research on the acute effects of concussion and the relationship to MSK injury risk.

先前脑震荡的国家橄榄球联盟运动员肌肉骨骼再损伤的评估

简介：据报道，大学生运动员脑震荡后肌肉骨骼 (MSK) 受伤的风险增加，但尚不清楚职业足球运动员是否有同样的继发性受伤风险。本研究的目的是确定美国国家橄榄球联盟 (NFL) 运动员的 MSK 损伤风险在脑震荡后是否增加。
方法：从公共网站收集 2013 年至 2017 年 NFL 受伤报告。脑震荡的运动员 (n=91) 与未受伤的对照组和发生肌肉骨骼 (MSK) 损伤的运动员同等匹配。
结果：在重返运动场后，与未受伤的对照组相比，脑震荡的运动员随后发生 MSK 损伤的可能性高出 2.35 倍（95% CI：2.35 [1.25, 4.44]，P= 0.01），但不比发生 MSK 损伤的运动员更有可能（P = 0.55）。同样，与对照组相比，发生 MSK 损伤的运动员随后发生 MSK 损伤的可能性不大（P = 0.08）。
讨论：职业足球运动员发生脑震荡后 12 周内 MSK 受伤的几率增加，需要进一步研究脑震荡的急性影响以及与 MSK 受伤风险的关系。
