目的:探讨低频神经肌肉电刺激对急性脑卒中偏瘫患者运动功能的影响。方法:80例急性脑卒中患者按前瞻性随机化原则分为电刺激组40例和对照组40例。两组常规治疗相同,电刺激组加用低频神经肌肉电刺激仪进行治疗,电极片置于偏瘫侧胫前肌及腓骨长、短肌的运动点上,刺激参数为频率30Hz,脉宽200μs,电流以患者最大耐受强度为限。每天治疗1次,每次30min,共2周(14次)。用Fugl-Meyer运动功能评定量表(FMA)中下肢部分评定下肢运动功能,用改良Barthel指数(MBI)评定ADL能力。结果:2组患者在治疗2周后,电刺激组与对照组的FMA评分及MB1总分比较,差异均有统计学意义(P<0.05)。结论:低频神经肌肉电刺激治疗能提高急性脑卒中后偏瘫患者运动功能。
Objective: To investigate the effects of low frequency neuromuscular stimulation on motor function in patients with hemiplegia after acute stroke. Methods: Eighty patients with acute stroke were divided into two groups according to the principle of prospective randomization: 40 cases in the electro-stimulation group and 40 cases in the control group. Two groups of conventional treatment the same, the electrical stimulation group plus low-frequency neuromuscular electrical stimulation for treatment, the electrode piece placed in the hemiparetic side of the anterior tibial and fibula long, short muscles movement point, the stimulation parameters for the frequency of 30Hz, pulse width 200μs, The current is limited to the patient’s maximum tolerated intensity. Treatment once daily, every 30min, a total of 2 weeks (14 times). Lower extremity motor function was assessed using the lower limbs of the Fugl-Meyer Motor Function Rating Scale (FMA), and the ADL ability was assessed using a modified Barthel Index (MBI). Results: After 2 weeks of treatment, FMA score and MB1 score of electro-stimulation group and control group showed statistically significant difference (P <0.05). Conclusion: Low-frequency neuromuscular stimulation can improve the motor function of patients with hemiplegia after acute stroke.
