早期穿戴弹力悬带矫形器对脑卒中患者步行功能恢复的影响

A new elastic suspension strap orthosis for stroke patients to improve their walking ability in the early stage of recovery

目的观察新型弹力悬带矫形器对脑卒中患者下肢运动功能及步行功能恢复的影响。方法共选取39例脑卒中患者，将其随机分为治疗组和对照组。2组患者均接受常规抑制肢体痉挛训练，治疗组同时穿戴本科室研制的弹力悬带矫形器进行步行训练，共连续治疗8周；对照组未穿戴弹力悬带矫形器，在治疗师指导下进行下肢步行训练。结果治疗组患者经早期穿戴弹力悬带矫形器辅助治疗8周后，发现其Fugl-Meyer下肢运动功能评分显著优于对照组；治疗4周、8周时治疗组功能性步行分级（FAC）达到4级的患者数量分别为3例（占15．7％）和15例（占78．9％），均显著优于对照组（P〈0．05）；在治疗8周时，治疗组FAC达到4级患者的10m步行时间明显短于对照组（P〈0．05）。结论早期应用弹力悬带矫形器可纠正脑卒中患者步态异常，提高步行速度，促进步行功能恢复，值得临床推广、应用。

Objective To explore the efficacy of a new elastic suspension strap orthosis, designed by the authors, in improving the motor function and walking ability of stroke patients. Methods Thirty-nine stroke patients less than 1 month after stroke were recruited and divided randomly into a treatment group and a control group. The patients in the treatment group accepted walking training with the assistance of an elastic suspension strap orthosis, 5 times a week for 8 weeks, while the control group accepted the same training without the assistance of the elastic suspension strap orthosis. Results The treatment group improved significantly more than the control group with regard to its average Fugl-Meyer score, the functional ambulation categories of its members, and their walking speeds. Conclusions The elastic suspension strap orthosis could help correct abnormal gait patterns, improve walking speed, and enhance the recovery of walking ability in stroke patients.
