Vocal, laryngeal and self-perception measurements of dysphonic teachers: analysis after voice therapy

PURPOSE: to analyze the results of evaluations vocals, laryngeal and self-perception after speech therapy in a group of dysphonic teachers. METHOD: this is a retrospective study carried out using a handbook review of 42 patients with hyperfunctional dysphonia, yielding data of hearing-perceptual and acoustic analysis, laryngeal exams and Voice Activity and Participation Profile (VAPP) before and after speech therapy. Patients were treated by students of speech language therapy, under supervision of a single professional using direct therapy, which consists in vocal techniques, and indirect, with exposure about vocal health care. RESULTS: in respect to hearing-perceptual assessment, 73,8% of voice samples were described as better in post treatment situation. The parameters grade of dysphonia (G) and roughness (R) most contributed for voice improvement. In acoustic analysis, there was significantly change after therapy for jitter, perturbation of frequency, shimmer and perturbation of amplitude parameters. Laryngeal analysis demonstrated that 43% have improved in visual-perceptual assessment after vocal therapy; 38% of the exams had no change with therapy and 19% were worst at discharge moment. Considering VAPP, was possible to verify significant improvement in post treatment situation for all parameters, and the biggest difference between the averages before and after vocal therapy refers to "effects of this alteration at work". CONCLUSIONS: there was an improvement of hearing-perceptual parameters grade of dysphonia (G) and roughness (R), acoustic parameters of perturbation of frequency and amplitude, in larynx image and a positive impact of voice in evaluated patient's quality of life after voice therapy.
