Abstract

Introduction: The vocal disorders are generally characterized by abnormalities of pitch and loudness or poor voice quality. These caracteristics can limit the efficiency of communication, causing loss of social or occupational order for the speaker. The vocal therapies for dysphonia can be direct or indirect. A procedure that has shown to be efficient when linked to the two forms of therapy in the dysphonia treatment in adults is the electromyographic biofeedback. This type of treatment may be considered an adjunctive therapeutic tool in voice disorders. Objective: to analyze the immediate and long-term effect of the electromyographic biofeedback associated with vocal therapy in the electrical activity of the supra-hyoid, infrahyoid, trapezius and sternocleidomastoid muscles, voice and larynx of dysphonic women. Method: will participate of the study 22 women with aged between 18 and 45 years old, with functional dysphonia, divided into two groups randomly: Group 1 (Experimental) - 11 women who will receive 8 sessions of biofeedback electromyographic in the sternocleidomastoid and supra-hyoid muscles, associated with vocal therapy (vibration, nasal and fricative sounds) for 30 minutes; Group 2 (Placebo) - 11 women who will undergo 8 sessions of biofeedback electromyographic placebo (same conditions as the G1, but there will be the regulation and control of the intensity of muscle activity of each exercise, performing the exercises will take place with the screen computer deleted) associated with voice therapy (vibration, nasal and fricative sounds) for 30 minutes. The evaluations will be performed before, immediately after, after one and three months of vocal therapy, and will consist of: questionnaire, otorhinolaryngologic evaluation, voice assessment (perceptual and acoustic analyses), surfasse electromyographic evaluation, self-assessment of pain symptoms, vocal symptoms and Voice-Related Quality of Life protocol . The data will be tabulated in Microsoft Excel program and will be analyzed statistically, comparing the two speech therapy groups, as well as before, post immediate, after one month, and after three months of therapy in both groups.
