What this Trial Is About
Researchers are evaluating the use of local translaryngeal vibration therapy combined with flow phonation voice therapy to treat muscle tension dysphonia (MTD), a common hyperfunctional voice disorder. This trial aims to determine the effectiveness of vibration therapy as an added treatment and to understand the relationship between treatment dose and clinical outcomes. The study addresses the ongoing challenge that current voice therapies often do not fully restore normal voice function or reduce voice handicap to typical levels. Participants will be randomly assigned to one of three groups: five weeks of voice therapy with vibration, eight weeks of voice therapy with vibration, or eight weeks of voice therapy with a placebo vibration device. All groups receive flow phonation voice therapy, and the vibration therapy is delivered through a novel device applied locally to the perilaryngeal area. The study uses a single-blind design to compare the effects of different vibration durations and the placebo. During the study, participants will undergo voice therapy sessions over either five or eight weeks, depending on their assigned group. Researchers will assess changes in voice handicap using the Voice Handicap Index from enrollment to the end of treatment. Secondary assessments include auditory-perceptual evaluation of voice quality. The study includes monitoring throughout treatment to evaluate clinical response and safety. Participation involves regular voice evaluations and therapy visits over the treatment period.
