Efeito do programa integral de reabilitação vocal em professoras com disfonia comportamental

Abstract

Purpose: Analyze the effects of the Comprehensive Vocal Rehabilitation Program (CVRP) and the motivational stages during speech therapy in teachers with behavioral dysphonia. Methods: Retrospective, longitudinal, observational study using data from the medical records of 33 teachers regarding auditory-perceptual, acoustic, self-perception analyses and the Voice Handicap Index (VHI-10) protocol in pre- and post-speech therapy situations, and motivational stages of adherence to treatment. Results: Auditory-perceptual assessment of the voice showed that 64.7% of the participants improved voice quality post-speech therapy. Comparison between the pre- and post-speech therapy moments showed that 82.4% of the teachers improved their voice according to self-perception. The VHI-10 showed no statistically significant difference between the pre- and post-speech therapy moments (p=0.879). Acoustic analysis of the voice showed improvement in the means of all evaluated parameters. Statistically significant correlation was observed in the analysis between the pre- and post-speech therapy moments only for the variables maximum phonation time and shimmer. Most of the teachers were at the stage of contemplation on the URICA-VOICE scale. No statistical significance was observed in the correlation analysis between VHI-10, auditory-perceptual assessment of the voice, maximum phonation time, and parameters of acoustic analysis with vocal self-perception of teachers and with auditory-perceptual assessment of voice. Conclusion: The use of CVRP for the treatment of behavioral dysphonia presented positive results in the pre-and post-speech therapy evaluation. As for motivation, the teachers strongly believed in the possibility of facing the problem, but still without much effort to change this situatio
