等速向心肌力训练对膝关节骨性关节炎患者关节功能水平的影响

目的:研究腿部肌群等速向心肌力训练对提高膝关节骨性关节炎患者关节功能水平的作用。方法:将膝关节骨性关节炎患者100例(168膝)随机分为两组,对照组50例(85膝),进行推髌骨、股四头肌训练及楔形垫行走训练等常规康复治疗;等速组50例(83膝),在常规康复治疗的基础上进行患腿肌群等速运动训练。所有患者均在治疗前和治疗后8周时接受等速肌力测试及采用Lysholm膝关节功能评分作为康复疗效判定标准。结果:经过8周的系统康复治疗,等速组与对照组患者的屈、伸肌峰力矩(PT)、总功量(TW)、平均功率(AP)和伸屈肌单次最大作功量(MRTW)均较前有改善,等速组改善较对照组更明显(P<0.01)。两组的患者的Lysholm评分均较前有改善,等速组Lysholm评分较对照组进步明显(P<0.01)。结论:等速向心肌力训练明显提高膝关节骨性关节炎膝部肌群力量,改善关节功能。

Effects of concentric isokinetic strength training on joint function of patients with knee osteoarthritis

Abstracts Objective: To investigate the effect of concentric isokinetic strength training on joint function of patients with knee osteoarthritis. Method: A total of 100 patients(168 knees) suffered from knee osteoarthritis were divided into isokinetic group(50 cases,83 knees) and comparison group(50 cases,85 knees).All 100 patients received the same conventional rehabilitation(containing the patella inside pushing, quadriceps trainings, and wedge-shaped cushion walking) for 8 weeks. In addition, isokinetic group patients received concentric isokinetic strength training for 8 weeks. The Lysholm scores of knee function and the parameters of peak torque(PT), total work(TW), average power(AP)and max rep total work(MRTW) were utilized to evaluate the effectiveness. Result: All the patients' Lysholm scores and the parameters of PT, TW, AP, MRTW increased significantly after therapy, but the isokinetic group were better than the comparison group, and there was statistically significance(P<0.01). Conclusion: The concentric isokinetic strength training can significantly increase the patients' leg muscles strength, and improved the function of knee joint.
