      摘要 目的：探讨多肌群协同收缩的功能性电刺激治疗系统对早期脑卒中患者下肢运动功能的影响。 方法：70例早期脑卒中患者随机分为治疗组和对照组，对照组采用常规康复治疗，治疗组在常规康复治疗的基础上，增加多肌群协同收缩的功能性电刺激治疗系统治疗，分别在入组时、入组治疗2周和4周后对患侧髋关节屈曲肌力(MMT)、股四头肌肌张力（MAS）、下肢Fugl-Meyer评分（FMA-LE）及Barthel指数（BI)进行评定，并进行统计学分析。 结果：治疗前两组患者的一般资料及MMT、MAS、、FMA-LE和BI评定结果均无显著性差异（P>0.05）；治疗2周、4周后，两组MMT、MAS、、FMA-LE和BI与治疗前对比，均有显著性意义（P<0.05）；治疗2周后，治疗组MMT、MAS和FMA-LE评分显著高于对照组，具有显著性意义（P<0.05），但是两组间BI评分无显著差异；治疗4周后，治疗组MMT、FMA-LE和BI评分显著高于对照组，具有显著性意义（P<0.05），但两组间MAS无显著性差异。 结论：多肌群协同收缩的功能性电刺激治疗系统对早期脑卒中患者下肢运动功能具有明显的临床促进作用。

Abstract:

      Abstract: Objective: To explore the effects of multi-muscles co-contraction based functional electrical stimulation(FES) on the lower extremities’ motor function among early stroke patients. Method: Seventy stroke patients were admitted. Eligible patients were randomly assigned in a 1∶1 ratio to receive either routine rehabilitation therapy plus multi-muscles co-contraction based FES (intervention group) or routine rehabilitation therapy only (control group). The measurements were taken respectively at the first interview， 2 weeks and 4 weeks after intervention， to explore if any significant difference between the results of two groups pre-and post-treatment. The Manual Muscle Test (MMT) on hip flexion of the involved side， the modified Ashworth scores (MAS) of quadriceps， FMA-LE (Fugl-Meyer Assessment Lower Extremities) and BI (Barthel index) were recruited as outcome measurements of this study. Result: Baseline characteristics and all initial measurements results were comparable between two groups(P>0.05). After analysis， there was great increase in all outcome measurements of post-treatment compared with baseline. Except BI，the increase in the MMT， MAS and FMA-LE scores was found significantly different between two groups two weeks later，with higher scores in the intervention group(P<0.05). Moreover，the statistically improvement in MMT，FMA-UE and BI were observed in intervention group 4 weeks later(P<0.05).However，no obvious difference was found in MAS. Conclusion: Lower limb dysfunction after stroke is an important issue to which rehabilitation clinicians should pay more attention. The clinical application of multi-muscles co-contraction based FES on the lower extremities’ motor function among early stroke patients is proved to be useful and may facilitate its recovery.
