等速运动训练用于治疗创伤性膝关节僵直的研究

A research on effects of isokinetic training on the function of traumatic stiff knee

目的:研究等速运动训练对创伤性膝关节僵直在功能方面改善的作用。方法:60例膝关节僵直患者被随机分为3组,每组各20例。第1组为等速运动训练组,只采用等速运动训练治疗;第2组为常规训练组,只采用常规运动疗法进行治疗;第3组为联合治疗组,行等速运动训练加常规运动疗法。三组患者分别在治疗前后行膝关节活动度(ROM)评定、美国特种外科医院(HSS)指数评定及等速肌力测试系统评定膝关节伸肌和屈肌的峰力矩值(PT)、峰力矩与体重比值(PT/BW)、平均功率[AP]、腘绳肌峰力矩/股四头肌峰力矩值(H/Q)。结果:三组治疗后屈曲度、伸直度、屈伸弧度均较治疗前有明显改善,在改善度数方面第3组优于第1组和第2组,第1组优于第2组;治疗后三组伸屈肌群PT、PT/BW、AP值均较治疗前有改善,第3组明显优于第1组和第2组,第1组优于第2组,三组治疗后H/Q值与治疗前比较无明显差异;三组治疗后HSS指数均有改善,但是第3组在HSS指数改善方面优于第1组和第2组,第1组优于第2组。结论:等速运动训练对关节僵直的疗效明显,可以很好地改善膝关节功能,临床上可以与常规运动疗法联合应用。

Objective： To observe the effects on the function of traumatic stiff knee after isokinetic training. Method： Sixty cases with traumatic stiff knee randomly were divided into the 1st group and the 2nd group, and the 3rd group. The 1st group received isokinetic training, the 2nd group received regular exercise therapy, and the 3rd group received isokinetic training and regular exercise therapy. Range of motion （ROM）, American hospital for special surgery（HSS） index, maximum peak torque （PT）, peak torque/body weight （PT/BW）, aver- age power （AP）, and hamstrings/quadriceps （H/Q） were assessed before and after the treatments in 3 groups. Result：The flexion degree, extention degree and flexion radian improved significantly after treatments all in 3 groups, in the 3rd group the improvement was more than that in both the 1st group and the 2nd group,and the 1st group had better change than the 2nd group.All the parameters of the isokinetic test improved signifi- cantly after training except H/Q all in 3 groups, in the 3rd group the improvement was more than that in 1st group and 2nd group,and the 1st group changed better than the 2nd group,while there was no significant difference in H/Q in 3 groups after treatments. The HSS index changed better after treatments in all 3 groups, the 3rd group improved more than both the 1st group and the 2nd group,and the 1st group changed better than the 2rid group. Conclusion： Effects on knee joint function of stiff knee after isokinetic training is evident. Therefore, it is worthy of clinical application combined with the regular exercise therapy.
