连续被动运动机对脑卒中偏瘫患者膝过伸的疗效观察

Observation on the effect of continuous passive motion machine on knee hyperextension in stroke patients with hemiplegia

目的 探讨连续被动运动(CPM)机改善脑卒中偏瘫患者膝过伸的临床效果。方法 选择2022年1月至10月江苏省徐州市中心医院收治的60例存在膝过伸的脑卒中偏瘫患者,按照随机数字表法分为两组,每组30例。对照组采取常规康复训练和蹲起训练,观察组采取常规康复训练和下肢CPM机训练,两组连续训练6周。比较两组治疗前及治疗6周后6分钟步行测试(6MWT)中膝过伸出现次数、患侧支撑相的膝伸展角度、步幅及步速。结果 治疗6周后,两组6MWT中膝过伸出现频次、患侧支撑相的膝伸展角度低于治疗前,且观察组低于对照组(P<0.05)。治疗6周后,两组步幅与步速高于治疗前,且观察组高于对照组(P<0.05)。结论 CPM机作为一种简单易于操作的辅助治疗方法,与常规康复训练结合能大大提高脑卒中偏瘫患者膝过伸的治疗效果。

Objective To investigate the clinical effect of continuous passive motion(CPM)machine on improving knee hyperextension in stroke patients with hemiplegia.Methods A total of 60 stroke hemiplegia patients with knee hyperextension admitted to Xuzhou Central Hospital,Jiangsu Province from January to October 2022 were selected.They were divided into two groups according to the random number table method,with 30 cases in each group.The control group received routine rehabilitation training and squatting training,while observation group received routine rehabilitation training and lower limb CPM machine training,both groups were trained continuously for six weeks.Knee hyperextension frequency in 6-minute walking test(6MWT),knee extension angle in the support phase of the affected side,stride length,and stride speed were compared between two groups before treatment and six weeks after treatment.Results Six weeks after treatment,knee hyperextension frequency in 6MWT and knee extension angle in the support phase of the affected side in both groups were lower than those before treatment,and observation group was lower than control group(P<0.05).Six weeks after treatment,stride length and stride speed in both groups were higher than those before treatment,and observation group was higher than control group(P<0.05).Conclusion As a simple and easy to operate auxiliary treatment method,CPM machine combined with conventional rehabilitation training can greatly improve the treatment effect of knee hyperextension in stroke patients with hemiplegia.
