Effectiveness and safety of the comprehensive rehabilitation program compared with vocal function exercises in behavioral dysphonia. A randomized controlled clinical trial

Abstract

Voice therapy is the best indication for the most voice disorders, with a strong degree of recommendation based on systematic reviews and randomized clinical trials with a predominance of benefit over risk. Some speech therapy techniques are specific, others are organized principles or with eclectic approaches, that use a combination of strategies. So far, few studies have tested the effectiveness of treatment for dysphonia due to time spent, safety and improved quality of life more comprehensive as they are made in clinical. The main objective of this work is to evaluate the effectiveness and safety of the Integral Rehabilitation Voice Program compared with Vocal Function Exercises in behavioral dysphonia. A hundred and six professional of voice with dysphonia behavior, above 18 years old and vocal complaints for more than six months. These professionals will be evaluated by an otolaryngologist, randomized to participate of Vocal Function Exercises group or Integral Rehabilitation Voice Program group. Both groups will be followed for six sessions with speech therapists and reassessed at the end of the period and after one month. The primary outcomes assessed are: reduction of IDV score, improved voice quality in the CAPE-V and improves the standard laryngeal. The Integral Program has an eclectic approach and follows the philosophy of what is practiced in clinics in Brazil. We believe this program can demonstrate the power of voice therapy effectiveness more organized, with shorter duration of treatment, benefit patient health and funding agencies such as SUS and health insurance.
