Previous studies have reported the factors contributing to chronic ankle instability, which could lead to more effective treatments. However, factors such as the reflex response and ankle muscle strength have not been taken into account in previous investigations.
Fifty recreational athletes with chronic ankle instability and 55 healthy controls were recruited. Peroneal reaction time in response to sudden inversion, isokinetic evertor muscle strength and dynamic balance with the Star Excursion Balance Test and the Biodex Stability System were measured. The relationship between the Cumberland Ankle Instability Tool score and performance on each test was assessed and a backward multiple linear regression analysis was conducted.
Participants with chronic ankle instability showed prolonged peroneal reaction time, poor performance in the Biodex Stability System and decreased reach distance in the Star Excursion Balance Test. No significant differences were found in eversion and inversion peak torque. Moderate correlations were found between the Cumberland Ankle Instability Tool score and the peroneal reaction time and performance on the Star Excursion Balance Test. Peroneus brevis reaction time and the posteromedial and lateral directions of the Star Excursion Balance Test accounted for 36% of the variance in the Cumberland Ankle Instability Tool.
Dynamic balance deficits and delayed peroneal reaction time are present in participants with chronic ankle instability. Peroneus brevis reaction time and the posteromedial and lateral directions of the Star Excursion Balance Test were the main contributing factors to the Cumberland Ankle Instability Tool score. No clear strength impairments were reported in unstable ankles.
先前的研究报告了导致慢性踝关节不稳的因素，这有助于更有效的治疗。然而，先前的研究并未考虑诸如反射反应和踝关节肌肉力量等因素。
招募了50名患有慢性踝关节不稳的休闲运动员和55名健康对照者。测量了对突然内翻的腓骨反应时间、等速外翻肌力量以及通过星标偏移平衡测试和Biodex稳定性系统进行的动态平衡。评估了坎伯兰踝关节不稳工具评分与每项测试表现之间的关系，并进行了向后多元线性回归分析。
患有慢性踝关节不稳的参与者表现出腓骨反应时间延长、在Biodex稳定性系统中表现不佳以及在星标偏移平衡测试中伸展距离减小。在外翻和内翻峰值扭矩方面未发现显著差异。在坎伯兰踝关节不稳工具评分与腓骨反应时间以及星标偏移平衡测试表现之间发现了中度相关性。腓骨短肌反应时间以及星标偏移平衡测试的后内侧和外侧方向占坎伯兰踝关节不稳工具评分差异的36%。
慢性踝关节不稳的参与者存在动态平衡缺陷和腓骨反应时间延迟。腓骨短肌反应时间以及星标偏移平衡测试的后内侧和外侧方向是坎伯兰踝关节不稳工具评分的主要影响因素。在不稳定的踝关节中未报告明显的力量损伤。
