目的:探讨2型糖尿病(2DM)患者周围神经病变(DPN)的肌电图变化及其影响因素。方法:采用肌电图仪对118例2DM患者和64例正常者进行正中神经、胫神经的神经传导速度(NCV)测定,并检测2DM患者空腹血糖(FBG)、糖化血红蛋白(HbA1c)水平。结果:有症状和无症状组的NCV均较正常组减慢,有症状组的NCV较无症状组减慢。结论:肌电图检查可以早期发现DPN。
Objective: To investigate the changes of EMG and its influencing factors in patients with type 2 diabetes mellitus (DM) with peripheral neuropathy (DPN). Methods: The median nerve and tibial nerve conduction velocity (NCV) were measured in 118 patients with 2DM and 64 normal controls by electromyography. The fasting blood glucose (FBG) and hemoglobin A1c (HbA1c) levels were measured in 2DM patients. Results: The NCVs in both symptomatic and asymptomatic groups were slower than those in the normal group, and the NCVs in the symptomatic group were slower than those in the asymptomatic group. Conclusion: Electromyography can detect DPN early.
