肌电图在糖尿病周围神经病变诊断中的应用价值分析

Diagnostic value analysis of electromyography in diabetic peripheral neuropathy

目的探讨肌电图在糖尿病周围神经病变诊断中的应用价值。方法选择我院2009-03—2012-06收治的231例糖尿病周围神经病变患者的临床资料,使用肌电诱发电位仪对患者的神经相关指标进行检测。结果神经肌电图总异常率高达78.8%,且随着病程的延长异常率的发生逐渐增加,D组异常率62.1%,A组异常率94.8%;D组胫神经H反射异常率达56.9%,其他项的检测异常率均<20%;A组胫神经H反射异常率最高达93.1%,其次是下肢的腓总神经MCV与腓浅神经SCV,异常率分别为41.3%和46.6%,均高于40%。结论神经肌电图在诊断糖尿病周围神经病变中具有较高的准确性,有利于早期发现其外周神经病变,从而早期进行治疗和干预,有利于患者的预后,值得临床应用。

Objective To investigate the diagnostic value of electromyography （EMG） in diabetic peripheral neuropa-thy.Methods 231 patients with diabetic peripheral neuropathy in our hospital from March 2009 to June 2012 were selected , and neurological related indicators were detected EMG by evoked potential instrument.Results Total abnormal rate of EMG was 78.8% ,and with the duration increasing incidence of abnormal rate increased ,from 62.1% in group with duration ＆lt;1years ,to 94.8 % in group with duration more than 10 years ;in patients with duration less than one year abnormal rate of tibi-al nerve H-reflex reached 56.9% ,abnormal rate of other items less than 20% ;while in patients with duration more than 10 years ,abnormal rate of the tibial nerve H-reflex up to 93.1% ,followed by the lower extremities peroneal nerve MCV and su-perficial peroneal nerve SCV ,abnormal rates were 41.3% and 46.6% ,all higher than 40%.Conclusion EMG has high accu-racy in the diagnosis of diabetic peripheral neuropathy ,detection by EMG in patients with diabetes can help early discovery of peripheral neuropathy ,thereby help early treatment and intervention ,and it is worthy of clinical application.
