摘　　要：目的:探讨功能性不稳踝关节的位置觉和肌肉力觉特征及其发生机制,为踝关节损伤防治和康复训练提供依据。方法:选取14名有单侧踝关节功能性不稳的受试者为实验组(FAI组),匹配14名无踝关节伤病的受试者作为对照组。测试受试者踝关节跖屈5°的被动定位并被动复位能力作为踝关节位置觉,计算位置觉的可变误差(VEJPS)和绝对误差(AEJPS)。测试受试者踝关节跖屈肌群对25%最大等长峰值力矩值的复制能力作为肌肉力觉,计算肌肉力觉的可变误差(RVEFS)和绝对误差(RAEFS)。采用2×2混合多元方差分析对比FAI组和对照组两侧踝关节本体感觉,检验水准均选0.05。结果:FAI组踝关节VEJPS和AEJPS与对照组之间差异无统计学意义(P>0.05),而RVEFS和RAEFS在两组之间的差异存在统计学意义(P<0.05);无论FAI组或对照组,受试者踝关节RVEFS、RAEFS、VEJPS和AEJPS在两侧之间的差异均无统计学意义(P>0.05)。结论:(1)功能性不稳组踝关节肌肉力觉较正常对照组显著不足,神经肌肉控制能力降低,而关节位置觉无明显差异;(2)受试者两侧之间踝关节本体感觉无显著性差异。Objective To examine the difference in proprioception of the ankle joint with functional instability through analyzing the joint position sense and force sense, in order to provide the basis for the prevention from and treatment on the sprained ankle. Methods Fourteen males subjects with uni- lateral functional ankle instability （FAI） were enrolled in the study, and other 14 healthy matched- paired subjects were served as controls. The target angle of the ankle passively reposition was set at 5° plantar flexion for measuring joint position sense and the target force of the muscle at 25% maximal voluntary isometric contraction for measuring muscle force sense. 2×2 mixed model ANOVA was used to compare the difference in proprioception between two the groups with and without FAI. Results The VEJPS （variable error of joint position sense） and AEJPS （absolute error of joint position sense） of FAI group were not significantly different from those of the control group （P 〉 0.05 ） . However, there was significant difference in the RVEFS （relative variable error of force sense） and RAEFS （relative absolute error of force sense） between the two groups （P 〈 0.05） . The RVEFS, RAEFS, VEJPS and AEJPS showed no significant difference between the two groups （P 〉 0.05 ） . Conclusion The dif- ference between FAI group and the control group was found not in the joint position sense, but in the muscle force sense. The ability of neuromuscular control for the FAI group was impaired. There was only one subject whose proprioception appeared to be normal.
