Use of Hooked-Wire Electrodes for Electromyography of the Intrinsic Laryngeal Muscles

Abstract

A new technique for electromyography of the intrinsic laryngeal muscles with bipolar hooked-wire electrodes is described in detail. This technique has the following important advantages for investigating speech activity: (1) it offers minimum discomfort to the subject, and consequently does not interfere with natural speech; (2) the electrodes stay in place regardless of rapid movements of the vocal cords or of the entire larynx during speech; and (3) it permits considerable localization of the area from which electrical activity is picked up.
