| 目的：探讨功能性踝关节不稳（FAI）患者踝关节背伸/跖屈（D/P）和外翻/内翻（E/I）峰值力矩比值与其姿势控制能力的相关性。方法：纳入符合标准的FAI患者30例，采用等速肌力测试评估患者健侧和患侧踝关节在不同角速度下的D/P值和E/I值，同时采用Pro-Kin 254评估患者健侧和患侧静态平衡能力、动态平衡能力和本体感觉，并将不同角速度下患侧踝关节的D/P值和E/I值分别与前后运动速度、左右运动速度、运动长度、运动椭圆面积、总体偏移指数、平均轨迹错误率和总负重标准差进行相关性分析。结果：与健侧足比较，FAI患者患侧足静态平衡能力（左右运动速度和运动长度）、动态平衡能力（总体偏移指数）和本体感觉（平均轨迹错误率和总负重标准差）均显著下降（P＜0.05）。FAI患者患侧踝关节在角速度60°/s和120°/s下的D/P值和E/I值均小于健侧（P＜0.05），其比值均与前后运动速度、左右运动速度、运动长度、运动椭圆面积、总体偏移指数、平均轨迹错误率和总负重标准差呈负相关（P＜0.05）。结论：FAI患者患侧踝关节的D/P值和E/I值与其姿势控制能力相关，将踝关节的D/P值和E/I值作为FAI患者姿势稳定性的临床评测指标具有一定的潜力。 |

| Objective: To explore the relationship between the ratio of dorsiflex/plantar (D/P) and eversion/inversion (E/I) peak torque of ankle and postural control function in functional ankle instability. Methods: Totally, 30 stroke patients were recruited for this study. Isokinetic muscle test was used to assess the ankle D/P and E/I value, and Pro-Kin 254 was used to assess the static balance ability, dynamic balance ability and proprioception. The correlation between the D/P value and E/I value and the affected ankle joint at different angular velocities and forward-backward motion velocity, left-right motion velocity, movement length, area of ellipse of motion, total deviation index, average trajectory error rate and standard deviation of total load was analyzed by the correlation analysis. Results: As compared with the unaffected ankle joint, the static balance ability (left-right motion velocity and movement length), dynamic balance ability (overall deviation index) and proprioception (average trajectory error rate and standard deviation of total load) of the affected ankle joint in FAI patients were significantly reduced (P<0.05). The D/P and E/I value of the affected ankle joint at 60°/sec and 120°/sec was significantly lower than that of the unaffected ankle joint (P<0.05), and that of the affected ankle joint at 60°/sec and 120°/sec was negatively correlated with forward-backward motion velocity, left-right motion velocity, movement length, area of ellipse of motion, total deviation index, average trajectory error rate and standard deviation of total load (P<0.05). Conclusion: The D/P value and E/I value of the affected ankle joint in FAI patients are related to their posture control ability, and have certain potential as the clinical evaluation index of the postural stability of FAI patients. |
