肌电图对糖尿病周围神经病的诊断价值

目的：探讨神经肌电图在糖尿病性周围神经病（DPN ）诊断中的应用价值。方法：选择我院2012年1月～2014年6月收治的200例DPN患者的临床资料，分析肌电诱发电位仪对患者的相关神经进行检测的结果。结果：在200例DPN患者中，神经电图总异常率高达71．5％。且随着病程的延长，其EM G异常率的发生逐渐增加。病程在1年以内的患者EM G异常率为40．8％，而病程在10年以上者异常率达到92．2％。病程在1年以内的患者H反射异常率为46．9％，而病程在10年以上者H反射异常率达到94％。其次是腓总神经运动传导速度（MCV）、腓浅神经感觉传导速度（SCV）异常率，分别是43．1％和58．8％，均超过40％。EM G结果提示：病程＜1年组拇短展肌、肱二头肌、胫前肌、趾总伸肌EM G异常率均为0，病程≥10年组异常率分别为17．6％、9．8％、21．5％、31．4％，同样随病程延长而异常率增加。结论：EM G在诊断DPN中具有较高的准确性，有利于早期发现和进行治疗。

Diagnostic value analysis of electromyography in diabetic peripheral neuropathy

Objective:To investigate the diagnostic value of electromyography(EMG)in diabetic pe‐ripheral neuropathy .Methods:200 patients with diabetic peripheral neuropathy in our hospital from Janu‐rary 2012 to June 2014 were selected ,and their related neurological indicators were detected by evoked potential instrument .Results:Total abnormal rate of EMG was 71 .5% ,and with the disease duration in‐creasing ,the abnormality rate increased ,from 40 .8 % in patients with 1 year duration to 92 .2% in pa‐tients with the duration of more than 10 years .In patients with the disease duration of less than one year , the abnormality rate of tibial nerve H‐reflex reached 46 .9% ,while in patients with the duration of more than 10 years ,the abnormality rate of tibial nerve H‐reflex up to 94% ,followed by the lower extremities peronral nerve HCV and superficial peroneal nerve SCV ,the abnormality rate were 43 .1 % and 58 .8 %respectively ,higher than 40% .In patients with duration less than one year abnormal rates of abductor pollicis brevis ,biceps brachii ,anterior tibial muscle ,extensor digitorum communis muscle was 0 ,while the abnormal rates of patients with the duration of less than one year were 17 .6% ,9 .8% ,21 .5% and 31 .4%respectively .Conclusion:EMG has high accuracy in the diagnosis of diabetic peripheral neuropathy .Detec‐tion by EMG in patients with diabetes can help early discovery of peripheral neuropathy ,early treatment and intervention .
