目的 探讨持续被动运动(continuous passive motion,CPM)对预防截瘫患者膝关节僵硬和肌肉萎缩的疗效.方法 将70例截瘫患者分为CPM组38例和对照组32例,CPM组应用CPM锻炼方法,对照组应用传统的被动锻炼方法.观察干预前后两组患者膝关节被动屈曲活动范围和股四头肌萎缩的情况.结果 CPM组膝关节活动范围受影响的程度明显小于对照组(P＜0.05),CPM组患者股四头肌萎缩发生率较对照组低(P＜0.05).结论 应用CPM锻炼方法可改善截瘫患者膝关节僵硬,预防股四头肌萎缩.%Objective To investigate the effect of continuous passive motion (CPM) on knee joint stiffness and myoatrophy of patients with paraplegia. Methods 70 patients with paraplegia were divided randomly into CPM group (n = 38) and control group (n = 32). The CPM group received continuous passive motion treatment, and the control group only underwent traditional passive rehabilitation treatment. The knee joint ranges of passive motion and quadriceps femoris atrophy state before and after rehabilitation were assessed. Results After stay in bed for some time, both CPM group and control group developed knee joint motion limitation to a certain degree. But the dysfunction of knee joint motion range (passive flexion ROM) of CPM group were significantly smaller than the control group (P < 0.05). The rate of quadriceps femoris atrophy in CPM group was significantly lower than that in control group (P < 0.05). Conclusion CPM may significantly improve knee joint dysfunction and myoatrophy of patients with paraplegia.
