What causes muscle tension dysphonia?
Muscle tension dysphonia (MTD) occurs when the muscles around the voice box are too tight during speaking, such that the voice box does not work efficiently. A person may work very hard to get voice out or use too much “muscle tension,” sometimes without even noticing it. MTD is a voice disorder related to how the voice is used. It does not occur when someone strains the voice one time. It is usually a problem occurring from a habit of straining to talk. Your voice may sound raspy or tight. Talking may make you feel tired, or you may even feel a muscle ache in the neck due to MTD.
