Multidimensional Assessment of the Effectiveness of Group Voice Therapy

Group voice therapy has been successfully used in patients with dysphonia, but there is little objectively documented evidence of its effects on voice quality and the self-perception of voice fatigue. The aim of this study was to investigate the effectiveness of group therapy in patients with functional dysphonia and minor anatomic vocal fold pathologies linked by appearance and history to voice use in an objective and multidimensional manner.Our findings provide evidence that group voice therapy can be associated with improvements in perceptual, acoustic, aerodynamic, and self-evaluated parameters in some patients with dysphonia. Controlled, randomized studies are needed in follow-up. This method of treatment may be a means of reducing the costs and waiting lists associated with rehabilitative treatment, and enhancing patients' motivation and compliance.
