肌电图检查对糖尿病周围神经病变预后判断的临床价值

目的 探讨肌电图检查对糖尿病周围神经病变预后判断的临床价值.方法 收集2011年1月～2013年1月来我院就诊的糖尿病周围神经病变患者32例,另选取同期来我院进行健康体检的30例作为正常对照组,比较两组的神经传导速度、运动与感觉神经波幅和潜伏期及观察组治疗前后各神经的异常率.结果 观察组不同损害程度患者治疗前正中神经、尺神经及腓总神经、腓肠神经的神经传导速度均明显慢于正常对照组（P＜0.05）.治疗后,观察组轻度损害患者的正中神经、尺神经及腓总神经、腓肠神经传导速度及胫神经H反射分别与对照组比较,无显著差异（P＞0.05）,中度损害和重度损害患者组间比较,差异也不显著（P＞0.05）,但中度损害和重度损害患者的正中神经、尺神经及腓总神经、腓肠神经传导速度及胫神经H反射分别与对照组比较,差异仍具有显著性（P＜0.05）.32例糖尿病周围神经病变患者治疗后正中神经MCV、SCV及F波异常率,尺神经MCV、SCV及F波异常率,腓总神经MCV 异常率、SCV 异常率、胫神经MCV异常率、F波异常率、H 反射异常率治疗后均较治疗前明显降低（P＜0.05）.结论 肌电图是评价神经和肌肉功能的一项重要手段之一,可有效评价糖尿病周围神经病患者的神经受损程度,为糖尿病周围神经病的诊断、治疗及预后提供有效的参考依据.

Clinical prognostic value of EMG on diabetic peripheral neuropathyClinical prognostic value of EMG on diabetic peripheral neuropathy

Objective To investigate the clinical prognostic value of EMG on diabetic peripheral neuropathy. Methods From January 2011 to January 2013 in our hospital for diabetic peripheral neuropathy in 32 patients, and the other se- lected the same time in our hospital health examination of 30 cases as normal control group, two groups of nerve con- duction velocity, motor and sensory nerve amplitude and latency and neurological abnormalities rate were observed of each group. Results The different extent of damage was observed in patients of observation group before treatment me- dian nerve, ulnar nerve and common peroneal nerve, the nerve sural nerve conduction velocity was significantly lower than the normal control group （P 〈 0.05）. After treatment, the observation group of patients with mild damage to the median nerve, ulnar nerve and common peroneal nerve, sural nerve conduction velocity and tibial nerve H-reflex compared with the control group, the difference was not significant （P 〉 0.05）, moderate and severe damage harm to patient groups, the difference was not significant （P 〉 0.05）, but moderate damage and severe damage to the pa- tient＇s median nerve, ulnar nerve and common peroneal nerve, sural nerve conduction velocity and tibial nerve H- reflex with the control group, respectively, the difference was still statistically significant （P 〈 0.05）. 32 cases of dia- betic peripheral neuropathy patients after median nerve MCV, SCV, and F-wave abnormality rate, the ulnar nerve MCV, SCV, and F-wave abnormality rate, abnormal rate of peroneal nerve MCV, SCV abnormal rate, tibial nerve MCV abnormal rate, F-wave abnormal rate, H reflex abnormal rate after treatment was significantly lower than before treatment, the difference was statistically significant （P 〈 0.05）. Conclusion EMG to evaluate nerve and muscle func- tion is an important method for patients with diabetic peripheral neuropathy nerve damage, ence for degree of diabetic peripheral neuropathy diagnosis, treatment and prognosis can provide effective refer-
