摘要
目的：探讨肌电图在评估突眼性甲状腺肿合并肌病患者的病程、病情、治疗效果中的作用。方法：对44例突眼性甲状腺肿患者检测正中神经和胫后神经共88条神经感觉传导速度(SCV)、运动末端潜伏期(ML)及波幅；F波潜伏期及出现率。并观察三角肌、股四头肌共88块肌肉的肌电图。结果：88条神经中有16条SCV减慢或波幅降低；12条ML延长或波幅降低。4条F波潜伏期延长，4条F 波出现率降低。检测88块肌肉，有5块肌肉出现自发电位，58块肌肉出现短时限多相运动单位电位，49块肌肉募集反应呈病理干扰相。结论：肌电图对突眼性甲状腺肿合并肌病有客观评价病情和疗效的作用。
Objective:To investigate the significance of electromyography in evaluating the Graves disease complicated with myopathy. Method: The sensory conduction velocity(SCV), motor distal latency (ML) and wave amplitued, F wave and its occurrence rate was detected in 88 nerves(median nerves and posterior tibial nerves) of 44 patients with Graves diseases and EMG of 88 muscles(deltoid and vastus medialis) were observed. Results:In 88 nerves,decreace of SCV of wave amplitude was noted in 16 ones, prolongation of ML or decreace of wave amplitude in 12 ones, prolongation of F wave latency in 4 and decreace of F wave occurrence rate in 4 nerves. Out of 88 muscles detected, 5 muscles showed pathological spontaneous potentials, 58 ones showed polyphasic, short duration and low amplitude of MUAP (66%). Fourty-nine muscles showed pathological recruitments(56%).The results of EMG and the clinical data demonstrated that the degree of muscle lesion have an positive relavation to the severe degree of the disease condition,and the longer the course of disease was ,the severe of the myogenic lesion. If the treatment was effectual ,the lesion muscles recovered significantly. Conchusion:EMG might have an important role in the diagnosis, evaluating the disease condition and therapeatic effect of Graves disease complicated with myopathy.[
