目的观察低频电刺激治疗对脑卒中偏瘫疗效,并分析其对患者周围神经电生理学与形态学的影响。方法选取本院94例脑卒中偏瘫患者,以数字表法随机分为两组,各47例,对照组接受基础康复治疗,实验组予以早期综合康复治疗(于对照组基础上进行低频电刺激治疗),比较两组治疗前后Berg平衡量表(BBS)评分、Fugl-Meyer运动功能(FMA)评分、关节(腕与踝)主动活动范围(AROM)、周围神经电生理学[感觉神经传导速度(SCV)、运动神经传导速度(MCV)、动态肌电图]与形态学[腕横纹正中神经(MN)横截面积(CSA)、宽度(W)以及厚度(T)]。结果实验组治疗后BBS评分、上肢与下肢FMA评分高于对照组(P＜0.05),腕与踝AROM大于对照组(P＜0.05);实验组治疗后腓总神经与胫神经SCV、MCV高于对照组(P＜0.05),肱二头肌与腓肠肌协同收缩率均低于对照组(P＜0.05);两组治疗前后MN的CSA、T比较无差异(P＞0.05),实验组治疗后MN的W大于对照组(P＜0.05)。结论低频电刺激联合早期综合康复治疗可有效提高脑卒中偏瘫患者平衡能力、关节活动度及上下肢功能,改善周围神经电生理学与形态学,减轻周围神经损伤。

Objective To observe the curative effect of low frequency electrical stimulation treatment on stroke hemiplegia, and analyze its influences on peripheral nerve electrophysiology and morphology of patients. Methods A total of 94 patients with stroke hemiplegia in the hospital were randomly divided into two groups by number table method, 47 cases in each group. The control group was given basic rehabilitation treatment, while experimental group was given early comprehensive rehabilitation treatment (low frequency electrical stimulation on basis of control group). The scores of Berg Balance Scale (BBS) and Fugl-Meyer assessment (FMA), joint (wrist, ankle) active range of motion (AROM), peripheral nerve electrophysiology [sensory conduction velocity (SCV), motor conduction velocity (MCV), dynamic electromyogram (EMG) ] and morphology [cross-sectional area (CSA) of carpal transverse median nerve (MN), width (W), thickness (T)] before and after treatment were compared between the two groups. Results After treatment, scores of BBS, upper and lower limbs FMA in experimental group were higher than those in control group (P<0.05), AROM of wrist and ankle was larger than that in control group (P<0.05). After treatment, SCV and MCV of common peroneal nerve and tibial nerve in experimental group were higher than those in control group (P<0.05), while co-contraction rates of biceps and gastrocnemius muscles were lower than those in control group (P<0.05). Before and after treatment, there were no differences in CSA and T of MN between the two groups (P>0.05). After treatment, W of MN in experimental group was greater than that in control group (P<0.05). Conclusion Low-frequency electrical stimulation combined with early comprehensive rehabilitation therapy may effectively increase the balance ability, joint range of motion and upper and lower limb function of stroke patients with hemiplegia, improve peripheral nerve electrophysiology and morphology, and reduce peripheral nerve injury.
