Analysis of Completed and Dropped-Out Cases of Voice Therapy, by Type of Disorder

Abstract

We investigated voice disorders in patients who received voice therapy, and no other therapy, at our hospital. Based on our previous experience, we chose an end point for the voice therapy of 6.0 sessions over a span of 3.5 months. For this study, we again divided the patients into two groups: those who completed the therapy and those who dropped out before completion. We investigated the end point of voice therapy for each disorder individually, and compared those individual results against the results, in terms of number of sessions and months of voice therapy, obtained earlier for all cases collectively. We found no significant differences. We therefore concluded that the timing of the end of voice therapy at 6.0 sessions over 3.5 months is valid for all types of voice disorder.
