Can voice therapy ease vocal cord strain? new study investigates
NCT ID NCT06165536
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how voice therapy works for people with vocal fold lesions (like nodules) caused by voice overuse. Researchers want to see if therapy reduces the pressure when vocal folds collide. 60 adults aged 18-40 with these lesions will be studied before and after voice therapy to measure changes in voice handicap and lesion severity.
