Weddel等1944年首先对喉肌作了肌电图检查,他们建议为了记录喉内肌的肌电活动需要用适当长度的同心针状电极(Concentric needle electrode),以便所有的操作能通过喉镜进行。Feinstein(1945年)和Macbeth(1946年)对声带麻痹的病人应用了新的试验。以后对喉内肌进行肌电图检查沿三种主要径路。一、通过咽部手术或喉裂开术切口直接径路:许多检查者通过这种外科手术的径路在直接观察下用同心的或双极的针状电极研究了喉肌的活动电位。这种径路对生理的研究和临床的实践都有明显的限制。
Weddel et al first performed an EMG examination of the laryngeal muscles in 1944 and recommended that an appropriate length of concentric needle electrode be used to record the myoelectrical activity of the laryngeal muscles so that all operations could be performed through the laryngoscope . Feinstein (1945) and Macbeth (1946) applied new tests to patients with vocal cord paralysis. After the EMG examination of the throat along the three main routes. First, through the throat surgery or laryngectomy direct incision incision: Many examiners through this surgical approach under direct observation with concentric or bipolar needle electrode activity of the larynx studied. This approach has obvious limitations on physiological research and clinical practice.
