To determine (1) the association between lifetime diagnosed concussion and lower extremity musculoskeletal injury (LE-MSI) among community rugby union players and (2) the sex specific risk of LE-MSI given concussion history among males and females.
Retrospective survey.
1037 (59.0% male, (612/1037), age: 31.6 ± 11.3 years) rugby players (10.1 ± 8.1 years played) completed an online survey to ascertain injury history. A chi-squared test of association was performed between concussion and LE-MSI; significant outcomes were followed-up with an odds ratio. A binary logistic regression with any LE-MSI (yes/no) as the outcome and concussion (yes/no) and sex (male/female) as predictors was performed to determine if there was a sex by concussion interaction.
There was an overall significant association between concussion and any LE-MSI(χ(1) = 13.055, p < 0.001, OR = 2.30 [95%CI: 1.45, 3.65]). Both male (OR = 2.21) and females (OR = 2.49) had significant associations for concussion and LE-MSI, but there were no differences between sex for risk of LE-MSI (R = 0.024, p = 0.999).
Community rugby players with a history of concussion are >2× more likely to also experience an LE-MSI than those without a history of concussion. There were no differences in the odds of LE-MSI between males and females with a history of diagnosed concussion. In line with current World Rugby injury prevention programs, future research should aim to reduce LE-MSI incidence to maximize player safety and wellness through targeted injury prevention and teams should utilize a conservative return to play protocols following concussion.
确定（1）社区英式橄榄球联盟球员中终生诊断的脑震荡与下肢肌肉骨骼损伤（LE-MSI）之间的关联，以及（2）在有脑震荡病史的男性和女性中，LE-MSI的性别特异性风险。
回顾性调查。
1037名（59.0%为男性，即612/1037，年龄：31.6±11.3岁）橄榄球运动员（参赛年限为10.1±8.1年）完成了一项在线调查以确定损伤史。对脑震荡与LE-MSI之间进行了关联的卡方检验；显著结果通过比值比进行后续分析。以任何LE-MSI（是/否）为结果、脑震荡（是/否）和性别（男/女）为预测因素进行二元逻辑回归，以确定是否存在脑震荡与性别的交互作用。
脑震荡与任何LE-MSI之间总体存在显著关联（χ(1)=13.055，p<0.001，OR=2.30[95%CI：1.45，3.65]）。男性（OR=2.21）和女性（OR=2.49）的脑震荡与LE-MSI均存在显著关联，但LE-MSI风险在性别之间无差异（R=0.024，p=0.999）。
有脑震荡病史的社区橄榄球运动员发生LE-MSI的可能性比没有脑震荡病史的运动员高2倍以上。有诊断脑震荡病史的男性和女性发生LE-MSI的几率没有差异。与当前世界橄榄球损伤预防计划一致，未来的研究应旨在通过有针对性的损伤预防降低LE-MSI发生率，以最大限度地提高运动员的安全性和健康水平，并且球队在脑震荡后应采用保守的复出比赛方案。
