[Electroglottography in the research and physiology of larynx].
Electroglottography (EGG) is a noninvasive method of monitoring the movement of the vocal folds by measuring the variation of impedance to a weak alternating current through the tissues of the neck. Basically EGG is an index of the vocal fold contact area. Despite recent controversy EGG continues being an easy to handle method in larynx basic research, with increasing use in clinical diagnosis and rehabilitation of vocal pathology. EGG technique is described and some of its applications in clinical practice and voice research are pointed out.
