Effectiveness of a Manipulative Method and Equipment in Treating Abductor Spasmodic Dysphonia

Abstract

Abductor spasmodic dysphonia is thought to be a form of dystonia. Its possible treatments include voice therapy and botulinum toxin injection to the posterior cricoarytenoid muscle. However, voice therapy in this instance has not been fully established, and previous reports indicate an efficacy rate of only about 30% with botulinum toxin injections. Here we report a new effective treatment for abductor spasmodic dysphonia using a sensory trick to press the back of the neck.
