目的 探讨肌电图对糖尿病患者周围神经测试的临床价值 ;并探讨周围神经病变的影响因素。方法 于 2 0 0 4 - 0 1～ 0 4上海市静安区医院 2 3例糖尿病患者空腹血糖、糖化血红蛋白和餐后 2h血糖 ,采用肌电图仪对腓总神经、腓浅神经进行测定。结果 肌电图测试结果与临床症状相符 ,具有神经症状的糖尿病患者轻收缩峰电压明显高于无神经症状的糖尿病患者 ,轻收缩峰平均时限延长 ,多相电位比数增大 (P <0 .0 0 1) ;病程明显较长 ,空腹血糖和餐后血糖控制不佳 ,差异有显著意义 (P <0 . 0 5 )。结论 高血糖的长期作用是造成糖尿病周围神经病变 (DPN)的基础因素 ,肌电图检测适用于临床检测糖尿病患者的神经功能。
Objective To investigate the clinical value of EMG on peripheral nerve in diabetic patients and explore the influencing factors of peripheral neuropathy. Methods Fasting blood glucose, glycosylated hemoglobin (HbA1c) and postprandial blood glucose (2h) were measured in 20 patients with diabetes mellitus in Shanghai Jing’an District Hospital from 2000 to 2001 and 0 to 40 patients respectively. The common peroneal nerve and peroneal nerve were measured by electromyography. Results The EMG test results were consistent with clinical symptoms. The peak systolic pressure of patients with neurological symptoms was significantly higher than that of patients without neurological symptoms. The mean time of light systolic peak was prolonged and the ratio of multiphase potentials was increased (P <0. The course of disease was significantly longer, with impaired fasting glucose and postprandial glycemic control, with significant differences (P <0.05). Conclusion The long-term effect of hyperglycemia is the basic factor causing diabetic peripheral neuropathy (DPN). EMG test is suitable for the clinical detection of neurological function in diabetic patients.
