摘　　要：目的：了解膝骨关节炎患者下肢动静态位置觉与下肢功能水平和动静态平衡之间的关系。方法对32例膝骨关节炎患者完成Lequesne患者指数评分、下肢动静态位置觉测试和动静态跌倒风险测试。进行Pearson相关性分析。结果患者双下肢中高频段姿势摆动系数和与Lequesne患者指数总分（r=0.36, P0.05）；健侧或较轻侧和患侧或较重患侧复位误差平均值与Lequesne患者指数总分（r=0.33~0.39, P〈0.05）、动态平衡跌倒风险指数（r=0.65~0.70, P〈0.05）、静态平衡跌倒风险指数（r=0.38~0.45, P〈0.05）正相关。结论膝骨关节炎患者下肢功能水平的下降会对维持机体平衡的本体感觉传入能力产生不良影响，从而导致其平衡能力的下降。Objective To study the relationship among static and dynamic position sense of lower extremity, physical function, and stat-ic and dynamic balance in patients with knee osteoarthritis. Methods 32 patients with knee osteoarthritis were tested with Lequesne Index, static and dynamic position sense of lower extremity, and fall risk of static and dynamic balance, and analyzed with Pearson correlation coef-ficient. Results The medium-to-high-frequency in postural sway correlated with Lequesne Index （r=0.36, P0.05）. The reposition accuracy error of the un-affected/mild-affected lower extremity and affected/severe-affected lower extremity correlated with Lequesne Index （r=0.33~0.39, P〈0.05）, the fall risk index of static （r=0.38~0.45, P〈0.05） and dynamic balance （r=0.65~0.70, P〈0.05）. Conclusion Lower extremity dysfunction post knee osteoarthritis would result in poor proprioception that maintains balance.
