| 摘 要： | 目的：探讨单侧功能性踝关节不稳者踝关节内外翻肌力特征。方法：选取15名患有单侧功能性踝关节不稳的受试者为实验组，匹配15名无踝关节伤病的受试者作为对照组。采用CON—TREX多关节等速力量测试系统对其进行踝关节内外翻肌力测试。结果：不管是向心收缩还是离心收缩，实验组踝关节内外翻肌力的相对峰值力矩都要明显小于对照组；而在外内翻峰值力矩比的比较中，两组间都没有显著性差异。结论：无论是向心运动还是离心运动，功能性踝关节不稳者惠侧足的内外翻肌力都存在严重不足，明显弱于正常人，其原因可能与踝关节损伤后造成的踝关节不稳有关。

| Abstract: | Objective To explore the ankle invertor and evertor characteristics of unilateral functional ankle in- stabilit. Methods 15 males subjects with unilateral functional ankle instability were enrolled in the study,and other 15 healthy matched-paired subjects were served as controls. The ankle invertor and evertor were measured using CON-TREX multi-joint isokinetic strength testing system. The independent samples t-test was used to compare the differences between two groups, the inspection level for α= 0.05. Result Whether it is in the contraction mode, or eccentric contraction mode, there were significant differences between the experimental group and the control group in ankle eversion and inversion of relative peak torque of muscle strength. While in the ankle invertor and evertor peak torque ratios comparison between the two groups, the differences are not significant. Conclusion： Whether it is in the contraction motion, or eccentric contraction motion, functional ankle instability is serious weaker than normal people in the injured foot of ankle invertor and evertor comparing, the reason may be related to the ankle instability caused by ankle injury. |
