The Assessment Methods of Laryngeal Muscle Activity in Muscle Tension Dysphonia: A Review

Abstract EN

The purpose of this paper is to review the methods used for the assessment of muscular tension dysphonia (MTD).

The MTD is a functional voice disorder associated with abnormal laryngeal muscle activity.

Various assessment methods are available in the literature to evaluate the laryngeal hyperfunction.

The case history, laryngoscopy, and palpation are clinical methods for the assessment of patients with MTD.

Radiography and surface electromyography (EMG) are objective methods to provide physiological information about MTD.

Recent studies show that surface EMG can be an effective tool for assessing muscular tension in MTD.
