摘　　要：目的:观察膝关节骨性关节炎(KOA)患者髋外展肌等速肌力变化。方法:采用Biodex system 4对23例双侧KOA患者及14例正常对照者进行角速度为30°/s及60°/s的髋外展肌等速肌力测试,分别采用配对样本t检验及独立样本t检验比较KOA患者主患侧与对侧、KOA组主患侧与正常对照组髋外展肌等速肌力。结果:KOA组30°/s峰力矩主患侧显著小于对侧(1.15 vs 1.22Nm/kg,P=0.039),峰力矩均值、单次最佳做功主患侧亦显著小于对侧(P<0.05),总功、平均功率无显著性差异(P>0.05);60°/s峰力矩主患侧显著小于对侧(1.03 vs1.13Nm/kg,P=0.006),峰力矩均值、单次最佳做功、总功、平均功率主患侧亦显著小于对侧(P<0.05)。髋外展肌30°/s峰力矩均值、平均功率、单次最佳做功及总功KOA组主患侧显著小于正常对照组(P≤0.05);60°/s时峰力矩KOA组显著小于正常对照组(1.03 vs 1.25Nm/Kg,P=0.032),余观察指标两组无显著性差异(P>0.05)。结论:膝骨关节炎患者主患侧髋外展肌等速肌力峰力矩、做功能力、运动效率较对侧减弱。膝骨关节炎患者髋外展肌等速肌力峰力矩、做功能力、运动效率较正常对照组减弱。Objective： To evaluate the differences in isokinetic strength of hip abductor in patients with Knee osteoartnrltlS （KOA）. Method： Twenty-three patients with diagnosis of bilateral KOA and 14 matched controls participated in the study. Isokinetic test of hip abductor for all the participators were tested by using Biodex system 4, and the test velocities were 30°/s and 60°/s. Using paired-sample t test and independent-sample t test respectively the isokinetic strength were compared between the mainly involved limbs and the contralateral limbs in patients, and between the mainly involved limbs in patients and the control group. Result： In patients with KOA, at 30°/s, the peak torque of hip abductor of the mainly involved limbs was ob servably lower than that of the contralateral limbs （1.15 vs 1.22Nm/kg, P=0.039）, and there were significant dif ferences in average peak torque and max repeat total work between the mainly involved limbs and the contra lateral limbs, but there was no significant difference in total work and average power. At 60°/s, the peak torque of the mainly involved limbs was observably lower than that of the contralateral limbs （1.03 vs 1.13Nm/ kg, P=0.006）, and there were significant difference, in the average peak torque, max repeat total work, total work and average power. At 30°/s there was no significant difference in peak torque of hip abductor between the groups （1.15 vs 1.35 Nm/kg, P=-0.056）, but there were remarkably differences in average peak torque, aver age power, max repeat total work, total work （P≤0.05）. At 60°/s only the peak torque of hip abductor in pa-tients with KOA was observably lower than control group （1.03 rs 1.25Nm/kg, P 0.032）. Conclusion： Patients with KOA exhibited lower peak torque, work capacity and efficiency of hip abductor of the mainly involved limbs than the contralateral limbs, and exhibited lower peak torque, work capacity and effi ciency of hip abductor than healthy controls.
