This study aimed to clarify the kinematic, kinetic characteristics associated with lateral ankle sprain.
A 16-month prospective cohort study.
Laboratory.
A total of 179 college athletes.
Joint kinematics, moment during single-leg landing tasks, and ankle laxity were measured. The attendance of each participating team, injury mechanism, existence of body contact, presence of orthosis, with or without medical diagnosis, and periods of absence were recorded.
Twenty-nine participants incurred lateral ankle sprain during non-contact motion. The Cox regression analysis revealed that greater knee varus peak angle (hazard ratio: 1.16 [95% confidence interval: 1.10-1.22], p < 0.001) and greater pelvic internal rotation peak angle toward the support leg were associated with lateral ankle sprain (hazard ratio: 1.08 [95% confidence interval: 1.02-1.15], p = 0.009). The cut-off values for each predictive factor were -0.17° (area under the curve = 0.89, p < 0.001) and 6.63° (area under the curve = 0.74, p < 0.001), respectively.
A greater knee varus peak angle and pelvic internal rotation peak angle after single-leg landing are predictive factors for lateral ankle sprain.
本研究旨在阐明与外侧踝关节扭伤相关的运动学和动力学特征。
一项为期 16 个月的前瞻性队列研究。
实验室。
共 179 名大学生运动员。
单腿落地时的关节运动学、力矩和踝关节松弛度。记录每个参赛队的出席情况、损伤机制、是否存在身体接触、是否使用矫形器、是否有医学诊断以及缺席时间。
29 名参与者在非接触运动中发生外侧踝关节扭伤。Cox 回归分析显示，膝关节内翻峰值角度较大（危险比：1.16 [95%置信区间：1.10-1.22]，p < 0.001）和支撑腿骨盆内旋峰值角度较大与外侧踝关节扭伤相关（危险比：1.08 [95%置信区间：1.02-1.15]，p = 0.009）。每个预测因素的截断值分别为-0.17°（曲线下面积为 0.89，p < 0.001）和 6.63°（曲线下面积为 0.74，p < 0.001）。
单腿落地后膝关节内翻峰值角度和骨盆内旋峰值角度较大是外侧踝关节扭伤的预测因素。
