Muscle tension dysphonia (MTD) is a prevalent voice disorder, causing up to 40% of voice-related complaints. The traditional treatment involves voice therapy (SLT-VT) administered by specialized speech-language therapists. However, a recent study protocol published in Pilot and Feasibility Studies investigates the feasibility of using Complete Vocal Technique (CVT), a structured pedagogic method, for treating MTD patients.
CVT, primarily used by singers and actors, aims to optimize vocal function. The study explores whether CVT, delivered by trained practitioners (CVT-Ps) via telehealth, can be beneficial for MTD patients. The primary outcome measure is the change in pre- and post-therapy scores of the Voice Handicap Index (VHI), with secondary outcomes including throat symptoms, acoustic/electroglottographic measures, and acceptability assessments.
Key findings from the feasibility study indicate:
- CVT-VT shows potential in improving vocal function in MTD patients, as evidenced by significant improvements in VHI scores.
- Telehealth delivery of CVT-VT is feasible and acceptable to patients, CVT-Ps, and SLT-VTs.
- Differences between CVT-VT and traditional SLT-VT techniques were observed, suggesting CVT-VT offers a novel approach to voice therapy.
For practitioners, integrating CVT principles into therapeutic practices can provide a systematic and scientifically supported method to enhance vocal outcomes. Moreover, the use of telehealth platforms ensures accessibility and continuity of care, crucial for ongoing therapy amidst constraints like the COVID-19 pandemic.
Encouraging further research, this study lays the groundwork for a larger pilot randomized controlled trial comparing CVT-VT and SLT-VT. Practitioners are urged to stay informed on emerging evidence and consider the potential benefits of incorporating CVT into their therapeutic repertoire.
