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.
