双下肢肌电图在糖尿病周围神经病变诊断中的应用分析

目的：探讨双下肢肌电图在糖尿病周围神经病变诊断中的应用。方法：回顾性分析148例2型糖尿病患者的双下肢肌电图数据，包括胫神经、腓总神经运动神经波幅及传导速度（MCV），腓浅神经感觉神经波幅及传导速度，胫神经F-波潜伏期，双足皮肤交感反应（SSR）波幅及潜伏期。结果：胫神经运动传导速度的异常率高于其波幅的异常率，皮肤交感反应波幅的异常率高于其潜伏期的异常率，差异有统计学意义（P﹤0.01）；腓总神经、F-波、皮肤交感反应的异常率高于胫神经和腓浅神经的异常率，差异有统计学意义（P﹤0.01）；临床诊断异常率与肌电图诊断异常率比较，差异有统计学意义（P=0.000）。结论：双下肢肌电图是糖尿病周围神经病变早期诊断的一种颇有价值的检查手段。

Application Analysis of Lower Limbs EMG in the Diagnosis of Diabetic Peripheral Neuropathy

Objective：To study the application of lower limbs EMG in the diagnosis of diabetic peripheral neuropathy. Methods：The data of lower limbs EMG of 148 cases of type 2 diabete were retrospectively analyzed,including the tibial nerve,peroneal nerve motor amplitude and conduction velocity,superficial peroneal nerve sensory amplitude and conduc-tion speed,F-wave latency of tibial nerve,amplitude and latency of foot skin sympathetic response. Results：The abnor-mal rate of tibial nerve motor conduction velocity was higher than amplitude;the abnormal rate of skin sympathetic re-sponse′s amplitude was higher than its latency. The difference was statistically significant（P ﹤ 0. 01）;Peroneal nerve,F-wave,and skin sympathetic response,s abnormal rate were higher than the Tibial and the Superficial peroneal nerve,s and the difference was statistically significant（ P ﹤ 0. 01）;Compared with the abnormal rate of clinical diagnosis and EMG diagnosis,the difference was statistically significant（ P = 0. 000）. Conclusion：Lower limbs EMG is a valuable means of checking in the early diagnosis of diabetic peripheral neuropathy.
