背景：踝关节内翻损伤在军队人群中很常见，但相关的生物力学危险因素在很大程度上是未知的。这项前瞻性研究探讨了压力和运动学变量之间的关联，以及皇家海军陆战队（RM）新兵踝关节内翻损伤的风险。据推测，一个更中间集中的压力在脚跟关闭阶段的立场，更大的冲动和峰值压力在第一跖骨头，更大的峰值rearfoot外翻角和更大的外翻偏移将与踝关节内翻injuries.Methods：数据从145名男性，受伤的RM新兵记录在第2周的32周的军事训练计划。每个新兵都以3.6 m s（-1）的速度沿着2 m的压力板完成了5次跑步试验，沿着2 m的压力板。同时记录运动学数据。在培训programme prospectively recorded.Findings：数据从11新兵谁遭受了踝关节内翻损伤RM培训期间与20个未受伤的对照进行了比较。伤后第一跖骨峰值压力、跖骨峰值冲量和离地压力集中度均显著高于对照组（P < 0.05）。组间运动学变量无差异。损伤组的体重低于对照组（P < 0.05）。解释：本研究的结果支持现有文献，提供证据表明，跑步时垂直力的内侧高度集中与踝关节内翻损伤风险增加有关。这可能是由于外侧踝关节韧带不太习惯于负荷，导致外侧韧带相对较弱，或韧带比对照组的韧带更不能够处理疲劳。皇冠版权所有（c）2013由爱思唯尔B.

Background: Ankle inversion injury is common in military populations but associated biomechanical risk factors are largely unknown. This prospective study examined the association between pressure and kinematic variables, and ankle inversion injury risk in Royal Marine (RM) recruits. It was hypothesised that a more medially concentrated pressure at the heel-off phase of stance, greater impulse and peak pressure at the first metatarsal head, greater peak rearfoot eversion angle and greater eversion excursion would be associated with ankle inversion injury.Methods: Data from 145 male, injury-free RM recruits were recorded in week-2 of a 32-week military training programme. Each recruit completed five running trials at 3.6 m s(-1), along a 2 m pressure plate. Kinematic data were simultaneously recorded. Injuries sustained during the training programme were prospectively recorded.Findings: Data from eleven recruits who had suffered an ankle inversion injury during RM training were compared with 20 uninjured controls. The injury group displayed a higher (P < 0.05) peak first metatarsal pressure, peak metatarsal impulse and more medially concentrated pressure at heel-off than control recruits. There were no differences in kinematic variables between groups. The injury group had a lower body mass than controls (P < 0.05).Interpretations: The findings from this study support existing literature, providing evidence that high medial concentration of vertical forces when running are associated with increased ankle inversion injury risk. This may be due to the lateral ankle ligaments being less accustomed to loading, resulting in relatively weak lateral ligaments, or ligaments less able to deal with fatigue than those of the control group.
