Concussion is one of the most common injuries in male professional Rugby Union ('rugby') and accounts for significant time loss from training and competition. Despite the most recent Concussion in Sport Group consensus statement recommending a focus on the identification of modifiable risk factors, limited evidence for their existence is available.
To investigate the association between cervical proprioception and concussion incidence in a group of professional male rugby players over the course of a full season.
165 players were assessed at pre-, mid- and end of season time points using the Cervical Joint Position Error Test (CJPET). Associations with diagnosed concussion injuries are presented as incidence rate ratios with 95% confidence intervals. We present the Incidence Rate Ratios (IRR) for a 10% increase in each variable and compared results against concussion using match minutes to account for risk exposure.
During the study period, 45 concussions were incurred by 44 players [or 19.7 concussions per 1000 player-match hours]. There was a significant association between right rotation repositioning error and concussion, with a 5% increase in concussion rate for each 10% increase in gross right rotation error (P = 0.021).
Poor gross right rotation repositioning error is a modifiable intrinsic risk factor for concussion in professional male rugby players. Interventions to improve proprioceptive function may act as an effective method for reducing concussion incidence in this population.
脑震荡是男性职业橄榄球联盟（“橄榄球”）中最常见的损伤之一，占训练和比赛中大量时间损失的原因。尽管最近的运动组脑震荡共识声明建议关注可改变的风险因素，但这些因素的存在证据有限。
在整个赛季中，研究一组职业男性橄榄球运动员的颈椎本体感觉与脑震荡发生率之间的关系。
在赛季前、中、末，使用颈椎关节位置误差测试（CJPET）对 165 名运动员进行评估。使用 95%置信区间的发病率比值报告与诊断性脑震荡损伤的关联。我们报告了每个变量增加 10%的发病率比值比（IRR），并根据比赛时间比较了结果，以考虑风险暴露。
在研究期间，44 名运动员中有 45 人发生了脑震荡[或每 1000 名运动员-比赛小时发生 19.7 次脑震荡]。右侧旋转重新定位误差与脑震荡之间存在显著关联，总右侧旋转误差每增加 10%，脑震荡率增加 5%（P=0.021）。
较差的总右侧旋转重新定位误差是职业男性橄榄球运动员脑震荡的可改变内在风险因素。改善本体感觉功能的干预措施可能是减少该人群脑震荡发生率的有效方法。
