About this study
Official title: The Effectiveness of the Comprehensive Voice Rehabilitation Program Compared With Vocal Function Exercises Method in Behavioral Dysphonia: A Randomized Controlled Clinical Trial.
The purpose of this study is to evaluate the effectiveness and safety of the Comprehensive Voice Rehabilitation Program compared with Vocal Function Exercises in behavioral dysphonia.
Read the 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.

| VFE voice therapy | Active comparator | Voice therapy: Vocal Function Exercises applied during 6 weeks Receives: Behavioral: Voice therapy |
| CVRP voice therapy | Experimental | Voice therapy: Comprehensive Voice Rehabilitation Program applied during 6 weeks Receives: Behavioral: Voice therapy |
What is being measured
The primary outcome is the main question the study is designed to answer.
Improvement of the vocal quality (assessed by two self assessment questionnaires)
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
Measured: 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 outcomes (2)
Perceptual auditory analysis (assessed by 3 senior SLP)
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.
Measured: 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)
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.
Measured: First assesment: in the beggining of the treatment; 2nd assesment: after 6 weeks of treatment; 3rd assesment: a month after the end of treatment.

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing Voice therapy in people with Dysphonia, run by Federal University of São Paulo.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 7 Apr 2015. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
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.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02409758, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Apr 2015; AzTrials last refreshed its copy on 27 Oct 2026.
