Abstrakt		In muscle tension dysphonia (MTD) excessive tension of both the internal and external laryngeal muscles is observed. In the present pilot study, 9 pairs of surface electodes were used to determine electromyographic (EMG) characteristics of different muscles in prioral area and anterior neck before and during phonation. Eleven patients with MTD and 5 normal speakers were included within the study. The result show a 6-8 fold increase of EMG activity and/or an alternation of the EMG activity level in the perioral and supralaryngeal muscles before and during phonation in most of the patients with MTD. It is not clear whether these muscles are activated as compensation for excessive tension of internal laryngealmuscles, or whether they are responsible for some of the voice disorders.
