1883年 Erb 氏首创感应—直流电试验。近20年来,电诊断的临床应用特别是肌电图及神经传导速度测定的应用颇广。本文介绍常用电诊断方法,并复习文献,探讨其临床应用价值。一、刺激试验法—根据肌肉对电刺激的收缩反应的质与量来作诊断。1.感应—直流电试验一般将非作用极置于背部相应节段(颈、 1883 Erb’s first induction - DC test. In the past 20 years, the clinical application of electrodiagnosis, especially electromyography and nerve conduction velocity measurement is quite wide. This article describes the commonly used diagnostic methods, and review the literature to explore its clinical value. First, the stimulation test method - according to muscle contraction of the electrical stimulation of the quality and quantity for diagnosis. 1. Induction - DC test is generally non-action pole placed in the corresponding segments of the back (neck,
