Dysphonia - spasmodic

Definition

Spasmodic dysphonia involves difficulty speaking because of repetitive or continuous contraction (dystonia) of the muscles that control the vocal cords.

The excessive activity of the vocal cord muscles drives the vocal cords either too close or too far apart, causing a hoarse sounding voice (known as adductor dysphonia) or a whispery, high-pitched voice (abductor dysphonia).
