等速训练对早中期髌骨软骨病的康复疗效研究

目的:在超短波和温针治疗的基础上,观察等速训练对早中期髌骨软骨病患者进行康复的效果。方法:将58例早中期髌骨软骨病单膝自愿患者随机分成等速组30例和常规组28例。2组均采用超短波、温针进行治疗;在此基础上,等速组用等速测力仪器进行康复训练,常规组进行常规的运动疗法康复;检测比较2组患者治疗前后大腿围度和角速度为60°/s时等速肌力测试峰力矩等指标,同时进行Lysholm膝关节评分和治疗后临床疗效比较。结果:治疗8周后,2组患膝屈伸肌PT、伸肌PT患/健侧比值及患侧PT屈/伸比均较治疗前有明显改善(P0.01),同时等速组在患膝伸肌PT和伸肌PT患/健侧比值上较常规组提高更显著(P0.05)。2组患膝大腿腿围和Lysholm膝关节功能评分均较治疗前明显提高(P0.01),等速组更高于常规组(P0.05)。治疗后,等速组总有效率明显高于常规组(P0.05)。结论:等速训练在早中期髌骨软骨病的康复中疗效显著。

Rehabilitative effectiveness of isokinetic training on chondromalacia patellae at early-middle stage

Objective: On the basis of remedy by ultrashort wave and acupuncture with warmed needle, to observe the curative effect of isokinetic training on chondromalacia patellae (CP) at early-middle stage. Methods: Fifty-eight voluntary sole knee patients with CP at early-middle stage were randomly divided into isokinetic group (n=30) and control group (n=28). Both two groups were treated with ultrashort wave and acupuncture with warmed needle. The isokinetic group was given rehabilitation training with isokinetic dynamometer, and control group was given conventional kinesiatrics. The indexes including thigh circumference, peak torque which were measured at 60°/sec with isokinetic dynamometer before and after the treatment were detected. Simultaneously, the knee Lysholm scores and the curative effectiveness after the treatment were compared. Results: After 8-week treatment, PT of extensor and flexor, the peak torque ratios for extensor of affected side to uninjured side, and peak torque ratios of the flexor to extensor on the affected side were all significantly improved as compared with those before treatment (P<0.01). At the same time, both PT of extensor and the peak torque ratios for extensor of affected side to uninjured side were significantly increased (P<0.05) in isokinetic group as compared with those in control group. The thigh circumference and the knee Lysholm scores were significantly increased (P<0.01) in both groups after treatment as compared with those before treatment, more significantly in isokinetic group than in control group (P<0.05). After treatment, the total effective rate in isokinetic group was obviously higher than that in control group. Conclusion: Isokinetic training has obviously therapeutic effects on the rehabilitation of CP at early-middle stage.
