摘　　要：目的：探讨神经肌电图（EMG）检测对肌炎辅助诊断的价值。方法：分析25例肌炎患者EMG检测中自发活动、运动单位电位（MUP）的时限、波幅及多相波、大力收缩时的募集形式，以及神经传导速度（NCV）检测。结果：25伪肌炎患者NCV均正常，排除了周围神经损害。针刺EMG检测均为肌原性损害，主要表现为插入电位延长（67％）、出现自发电位（88％），MUP时限缩短（90％）、MUP波幅降低（90％）、多相渡增多（91％），大力收缩时波型异常（93％）。结论：神经EMG检测是协助临床诊断肌炎的重要手段，能够客观地反映肌肉炎性病变程度，对提高肌炎的临床诊断、转归有着重要的意义。Objective： To investigate the value of electromyogram （EMG） in the diagnosis of myo- sitis. Methods：EMG records of 25 patients with myositis were analyzed including fibrillation, mean dura- tion of motor unit potentials （MUP）, mean amplitude of MUP, polyphasie, recruitment patterns of max- imum voluntary contraction and nerve conduction velocity （NCV）. Results： 25 cases with myositis in nerve conduction tests were normal, excluding the peripheral nerve damage. EMG mainly showed myo- genic damage prolonged insertion potential （67%）, increased spontaneous potential （88%）, shortened MUP duration （900%）, decreased amplitude （90 %） and increased polyphasie potential （91 % ）. The ab- normality rate in heavy contraction was 93 %. Conclusion： EMG is an important means of diagnosis of my- ositis. It can reflect objectively the dramatic level of muscular infammatory degeneration and has guiding significance in clinical prognsosis.
