摘要

目的:本研究的目的是评估慢性踝关节不稳定(“coopers”)患者在疲劳状态下的静态姿势稳定性,并与健康对照进行比较。方法对60名年轻、体力活动的受试者进行前瞻性研究,将其分为3组:I- 14例单侧踝关节不稳,II - 15例双侧踝关节不稳,31例健康、无踝关节不稳。疲劳试验基于改进的短期疲劳方案。采用HUR平台进行静稳定。结果研究人群ⅰ疲劳后COP微量长度值升高,疲劳前COP微量长度Z水平显著低于疲劳后。研究人群1的受试者与对照组相比,COP痕量长度Z水平较高。对该群体的主要影响也被证明是显著的。研究人群1与对照组相比,COP痕量长度Z水平较高。疲劳后的测量仅在研究人群1和对照组之间有显著差异。结论1。结构性踝关节不稳定的发生率与功能性不稳定无关。踝关节不稳定的受试者,或“copers”,具有良好的功能水平,使他们能够进行体育活动。2. “Copers”在静态稳定性试验中削弱了本体感觉。

The impact of fatigue on static balance in people with chronic ankle instability
Purpose The aim of the study was to assess static postural stability under fatigue in subjects with chronic ankle instability – “coopers” in comparison to healthy controls. Methods We conducted a prospective study on a group of 60 young, physically active subjects, who we divided into 3 groups: I- 14 subjects with unilateral ankle instability, II - 15 subjects with bilateral ankle instability, 31 healthy subjects, without ankle instability. The fatigue trial was based on modified Short-Term Fatigue Protocol. Static stabilography was performed with the use of HUR platform. Results Results showed an increase in the value of COP trace length after fatigue test in study population I. The level of COP trace length Z before fatigue was significantly lower than after fatigue. Subjects from study population I had higher levels of COP trace length Z in comparison with the control group. The main effect for the group also proved to be significant. Study population I had higher levels of COP trace length Z in comparison with the control group. For the measurement after fatigue there was significant difference only between the study population I and the control group. Conclusions 1. The incidence of structural ankle instability was not correlated with functional instability. Subjects with ankle instability, or “copers”, had good functional levels, enabling them to perform sports activities. 2. “Copers” had weakened proprioception in static stabilography tests.
