RESUMO
PURPOSE: To evaluate a population of dysphonic treated in rehabilitation by comparing the VHI score and GRB scale. MATERIALS AND METHODS: 300 questionnaires were completed, only 42 cases were matched before and after 15 rehabilitation sessions; that is 84 questionnaires. Patients were divided into two groups: group 1 (impaired mobility of the vocal cords), group 2 (benign mucosal lesions). All patients completed a VHI questionnaire, a questionnaire evaluating subjective voice abuse (SSVS), a GRB score. The two tests were correlated to the diagnosis of voice pathology but also used for follow up after voice therapy. The tests used for statistical studies were: comparison by pathology by unpaired series tests (theoretical deviation=0); mean tests, Wilcoxon type. RESULTS: Patients were more handicapped by impaired mobility of the vocal cord than by a nodule or a cyst. The patients' vocal handicap (VHI) was significantly lower after 15 therapy sessions, in all of its components. The perceptual evaluation GRB is also significantly better for these patients after 15 therapy sessions. We could not demonstrate a favorable evolution, that is a diminution of the SSVS before and after 15 sessions. CONCLUSION: The efficacy of speech therapy for certain vocal cord pathologies has been demonstrated both in respect of the Vocal Handicap felt by the patient as well as the Hirano scale.
