Detailed Description

Introduction: 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. Objective: To evaluate the effectiveness and safety of the Comprehensive Voice Rehabilitation Program compared with Vocal Function Exercises in behavioral dysphonia. Methods: 106 professional of voice with dysphonia behavior, between 18 and 50 years old and vocal complaints for more than six months. These professionals have been evaluated by an otolaryngologist, randomized to participate of Vocal Function Exercises arm or Comprehensive Voice Rehabilitation Program arm. Both arms were follow for six sessions with speech therapists and reassessed when finish the period and after one month. The primary outcomes assessed are: reduction of VHI score, improved voice quality in the CAPE-V and improves the larynx condition. Conclusions: The Comprehensive Voice 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 to solve problems, with shorter duration of treatment, benefit patient health and funding agencies such as Unified Public Health System (SUS) and health insurance.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Improvement of the vocal quality (assessed by two self assessment questionnaires)
Time Frame: First assesment in the beggining of the treatment; 2nd assesment after 6 weeks of treatment; 3rd assesment a month after the end of treatment.
The improvement was assessed by two questionnaires of self assessment vocal quality: Voice Related Quality of life questionnaire (VRQOL) and Voice Handicap Index (VHI) in the three different moments: pre therapy, post therapy and one month after therapy
First assesment in the beggining of the treatment; 2nd assesment after 6 weeks of treatment; 3rd assesment a month after the end of treatment.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Perceptual auditory analysis (assessed by 3 senior SLP)
Time Frame: First assesment in the beggining of the treatment; 2nd assesment after 6 weeks of treatment; 3rd assesment a month after the end of treatment.
The general grade of hoarseness was assessed blindness by 3 senior SLP in the three different moments: pre therapy, post therapy and one month after therapy. The 3 SLP assessors was blinded according to kind of therapy and moment of evaluation.
First assesment in the beggining of the treatment; 2nd assesment after 6 weeks of treatment; 3rd assesment a month after the end of treatment.
Improvement of larynx (evaluation by blind assessor)
Time Frame: First assesment: in the beggining of the treatment; 2nd assesment: after 6 weeks of treatment; 3rd assesment: a month after the end of treatment.
Evaluation of the larynx by a senior otorhinolaryngologist in the three different moments: pre therapy, post therapy and one month after therapy. The otorhinolaryngologist assessor was blinded according to the kind of therapy and moment of evaluation.
First assesment: in the beggining of the treatment; 2nd assesment: after 6 weeks of treatment; 3rd assesment: a month after the end of treatment.
