Translaryngeal Vibration for Hyperfunctional Voice Disorders

Sponsor

Texas Christian University

Enrollment

30 participants

Start Date

Sep 1, 2024

Study Type

INTERVENTIONAL

Conditions

Dysphonia Muscle Tension Dysphonia

Summary

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.

Eligibility

Min Age: 18 Years

Inclusion Criteria1

a) diagnosis by an otolaryngologist of hyperfunctional dysphonia (MTD) without benign mid-membranous lesion (i.e., primary MTD or non-phonotraumatic hyperfunction) with and a recommendation for voice therapy, ((b) confirmation of dysphonia by a comprehensive voice evaluation conducted by a speech-language pathologist with experience in the evaluation and treatment of voice disordered populations, (c) to prevent floor effects of our primary outcome variable, participants will be required to exhibit a pre-treatment VHI score of \>20, as this is the upper range for normal cutoff values in studies which have demonstrated high sensitivity and specificity for this tool (Behlau et al., 2016), (d) 18 years of age or older, (e) no history of local vibration therapy as part of a rehabilitation treatment program.

Exclusion Criteria1

Unable to receive vibration to neck area

Interventions

BEHAVIORALVoice therapy with vibration

Voice therapy with a novel vibration device will be delivered for five or eight weeks depending on group allocation. All participants will receive flow phonation voice therapy.
