[en] Twenty six patients with dysphonia (different etiologies) were submitted to a voice therapy program involving the use of Eutony. In order to assess its efficacy, pre and post-treatment audio recordings were analysed and submitted to perceptual rating using GRBAS-I scale and acoustical analysis of fundamental frequency, jitter and shimmer. Aerodynamic data (Maximum Phonation Time & Estimated Subglottic Pressure) were also included in the voice quality assessment protocol.
In addition , a questionnaire was sent to all patients to collect self-evaluation of voice quality and therapy outcomes.
The study revealed a significant improvement lasting in time for two acoustic parameters : Jitter and Shimmer and five perceptual parameters : Grade, Roughness, Breath, Asthenia and Strain. Aerodynamic data showed slight improvements but no significant changes. Self evaluation questionnaires also tend to strengthen positive effects of therapy.
Thus, this study supports the use of Eutony in vocal therapy for dysphonia. Its effects were shown to be measurable with both acoustical analysis and perceptual rating of voice quality.
