摘　　要：目的:探讨神经肌炎的临床特点以及肌电图(EMG)、神经传导速度(NCV)的诊断价值。方法:分析13例神经肌炎临床表现、EMG、NCV结果。结果:13例患者均以肌肉受累为主要临床表现;11例并发有神经病变的症状及体征。13例患者NCV均有异常。所检测的104根神经NCV异常率为57.7%。F波异常率为26.9%。11例针极EMG呈神经源性与肌源性混合损害,2例呈神经源性损害。结论:EMG、NCV是有价值的电生理诊断方法。确诊神经肌炎需结合临床表现和EMG结果。Aim： To investigate the value of the clinical manifestations, electromyogram（EMG） and nerve conduction velocity （NCV） in the diagnosis of neuromyositis. Methods： The clinical features, EMG and NCV of 13 patients with neuromyositis were analyzed. Results： All the 13 cases presented with muscle weakness in the both proximal limbs, muscular fatigue and myalgia. There were 11 cases who showed numbness in the distal extremities, diminution or loss of tendon reflexes, glove- and stocking-types of sensory disorders and several cases who complained radicular pain. 13 patients all have a different degree abnormality in NCV, whereas 57.7 % （60/ 104） were imperfection in 104 nerves which had been detected. The abnormality rate of the F-wave is 26.9% （7/26）. The needle electromyogram manifested 11 neurogenic changes combined with muscular unconventionality and 2 neurogenic changes alone. Conclusion： EMG and NCV are valuable in diagnosing neuromyositis. It is necessary to combine the clinical presentations and the laboratory changes to make a diagnosis.
