Translaryngeal Vibration for Hyperfunctional Voice Disorders

Contemporary treatments for hyperfunctional voice disorders such as muscle tension dysphonia (MTD) are effective but typically do not restore voice handicap or voice function to normal thresholds. Recent reports of vibration as a voice therapy modality have been published, but many questions remain about the efficacy of this tool. The current project addresses these problems through a blinded and randomized controlled trial to investigate the efficacy of local translaryngeal vibration for MTD and the dose-response relationship of this modality when compared to treatment without vibration.
