摘　　要：目的:对功能性踝关节不稳(FAI)运动员与非运动员踝内外翻肌进行等速向心及等速离心测试的对比分析,为进一步康复提供依据。方法:使用BiodexSystem-3型等速肌力测试训练系统对35例运动员FAI患者及21例非运动员普通人群FAI患者分别进行踝关节内、外翻等速向心及离心(角速度均为30°/s×5次;180°/s×10次)的测试。结果:运动员FAI患者除了高角速度离心运动时,踝外翻肌群力矩低于同组健侧外,踝内、外翻肌群在低角速度向心、低角速度离心及高角速度向心的力矩均未低于健侧(P>0.05);而普通FAI患者存在踝内外翻肌群在各种角速度时普遍性肌力缺陷、关节活动度降低及I/E比值的升高(P<0.05)。结论:不同人群FAI患者力矩改变特点不同,选用等速仪器中I/E比值并作动态控制率的分析,有利于制定更有针对性的康复处方。Objective： To study the functional changes in isokinetic concentric and eccentric muscle strength of the ankle invertor and evertor in athlete and non-athlete subjects with functional ankle instability（FAI）, in order to provide the reasonable rehabilitation program. Method： Biodex System-3 isokinetic test system was used to assess the isokinetic concentric and eccentric muscle strength of ankle invertor and evertor at two angular velocities （30°/s × 5; and 180°/s × 10） in 35 athletes and 21 non-athlete with FAI. Result： In athlete group, the torque of ankle invertor and evertor of involved limbs was no less than that of uninvolved limbs in concentric and eccentric contraction at low angular velocity and concentric contraction at high angular velocity（P 〉 0.05）, except the torque of ankle evertor decreased in eccentric contraction at high angular veloc- ity. In non-athlete group, the strength of invertor and evertor of ankle decreased significantly comparing with that of uninvolved limbs in concentric and eccentric contraction at all angular velocities （P〈0.05）. Besides, AROM of involved ankle decreased and the invertor/evertor ratio （I/E） of involved ankle increased comparing with that of uninvolved ankle（P〈0.05）. Conclusion： Since the muscles torque of different subjects with FAI had different features, the I/E and dynamic control rate obtained from isokinetic test need to be analyzed together in order to make rational rehabilitation program.
