目的：探讨肌电图动态监测在脑梗塞后偏瘫行电刺激联合康复治疗中的临床价值。方法：选取我院2013年1月-2015年1月我科收治的100例脑梗塞后偏瘫患者，随机分为观察组和对照组，每组50例，观察组给予肌电图定位定量下电刺激联合康复治疗，对照组给予低频电脉冲联合康复治疗，治疗过程中均行肌电图仪持续监测，分析相应神经在刺激前后的电学变化。结果：观察组治疗后桡神经的传导速度为（53.93±3.92）m/s，明显快于治疗前，并快于对照组（47.31±3.91）m/s，其组内和组间差异均有统计学意义，p<0.05；观察组正中神经传导速度为（54.08±3.71）m/s，明显快于治疗前，并快于对照组（46.09±4.12）m/s，p<0.05；观察组尺神经的传导速度为（54.38±3.69）m/s，明显快于治疗前，并快于对照组（47.47±4.26）m/s；治疗后两组患者的运动电位潜伏期明显缩短，波幅增大，但治疗组较对照组更明显，p<0.05。结论：肌电图仪定位定量下电刺激联合康复治疗脑梗塞后偏瘫患者，可有效促进周围神经再生及神经功能恢复，值得临床推广使用。“,”To study the clinical value of dynamic monitoring of electromyography in cerebral infarction hemiplegia after electrical stimulation combined with rehabilitation treatment. Methods 100 patients of hemiplegic after cerebral infarction in our hospital from January 2013 to January 2015 were randomly divided into the observation group and the control group, 50 cases in each group.The observation group was given the quantitative EMG positioning under electrical stimulation combined with rehabilitativetreatment, the control group was given low frequency electric pulse combined with rehabilitation therapy, the treatment process were underwent EMG instrument for monitoringand analysis of the corresponding neural electrical changes before and after stimulation and. Results The observation group after treatment of radial nerve conduction velocity was (53.93+3.92) m/s, significantly faster than before treatment, and faster than the control group(47.31+3.91) m/s, the significance of within group and between group differences were statistically p<0.05;the observation group median nerve conduction velocity was (54.08+3.71) m/s. Significantly faster than before treatment, and faster than the control group (46.09+4.12) m/s, p<0.05;the conduction velocity of ulnar nerve in observation group was (54.38+3.69) m/s, significantly faster than before treatment, and faster than the control group (47.47+4.26) m/s;after treatment, two groups of patients with motor evoked potential latency was significantly reduced in short, the amplitude is increasing, but the treatment group was better than that of control group, p<0.05. Conclusion Quantitative electromyography localization ofelectrical stimulation combined with rehabilitation on hemiplegic patients after cerebral infarction, can effectively promote the regeneration of peripheral nerve and recovery of nerve function, is worthy of clinical use.
