Preliminary Study 2 to Test the Effects of Ambulatory Voice Biofeedback

Muscle Tension Dysphonia Clinical Trial

Official title: Preliminary Study 2 to Test the Effects of Ambulatory Voice Biofeedback in Small Groups of Patients With Vocal Hyperfunction

Status Completed

Clinical Trial Summary

Patients with vocal hyperfunction will undergo standard of care voice therapy with ambulatory voice monitoring before therapy and after the first 3 voice therapy sessions. Biofeedback will be added to ambulatory monitoring after the 2nd voice therapy session only.

Clinical Trial Description

This study will use a single subject design to determine if adding ambulatory voice biofeedback to conventional voice therapy can result in faster carryover (generalization) of new vocal behaviors established during voice therapy to daily life. Here, ambulatory voice biofeedback will be based on objective measures that have subject-specific sensitivity to vocal hyperfunction. Hypothesis: The ambulatory voice biofeedback week (week 2) will result in higher generalization percentages when compared to baseline and the week prior to the initiation of biofeedback (week 1). This effect will be retained when the biofeedback is removed (week 3), thus it will be different than baseline and week 1, but not different than week 2. ;
