1 Introduction Laryngeal dystonia (LD), also known as spasmodic dysphonia [1], is a movement disorder involving uncontrollable, repetitive muscle contractions of the larynx. LD is a form of isolated focal dystonia of the laryngeal adductor and/or abductor muscles. Task specificity is a hallmark of the disorder, with speaking ability being greatly affected while other vocal activities such as whisper remain intact [1].
