Semi-occluded Vocal Tract Exercise in Velopharyngeal Dysfunction in Patients With Cleft Palate

May 28, 2019 updated by: Hospital de Clinicas de Porto Alegre

Exercise Of Semi-Occluded Vocal Tract In Velopharyngeal Dysfunction In Patients With Cleft Palate : Effects Of Short-Term

Analyze the effect of SOVTE (Semi-occluded Vocal Tract Exercise), with high resistance tube, on the velopharyngeal mechanism, for speech rehabilitation of twelve patients with cleft palate with vocal alterations, after four weeks. The study was developed in the city of Porto Alegre, southern Brazil. The hypothesis of the study is that after four weeks of exclusive therapy with exercise it will be improvement in the voice of patients with cleft palate.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The study is an uncompared before-after clinical trial. All patients were submitted to videonasoendoscopy and had their vocal emissions recorded before and after the four weeks of speech therapy. These individuals were submitted to multidimensional evaluation comprised of analysis of images generated by specialized videonasoendoscopy software, analysis of speech emissions by perceptual-auditory evaluation and acoustic analysis, and vocal self-assessment.

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.

Ages Eligible for Study

6 years and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Individuals with surgically repaired CLP (Cleft lip and palate), regardless of gender and regardless of the type of clef palate.
  • The sample only included patients aged 6+ because this is the ideal age to be submitted to videonasoendoscopy.
  • These patients attended four speech therapy sessions.
  • All individuals agreed to participate in this research voluntarily.

Exclusion Criteria:

  • Individuals with cleft lip and palate associated with genetic syndromes or other congenital malformation
  • Individuals who proved unable to do SOVTE (Semi-occluded Vocal Tract Exercise),
  • No condition to be submitted to videonasoendoscopy examination,
  • Patients who did not attend the four sessions of therapy or who did not do exercise at home were excluded from the sample.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Group before-after
Speech therapy with Semiocluded vocal tract exercise.
Behavioral: Group before-after
The group was submitted to four weeks of speech therapy intervention with Semiocluded vocal tract exercise. The 12 participants were evaluated before and after the intervention with a multidimensional evaluation comprised of analysis of images generated by specialized videonasoendoscopy software, analysis of speech emissions by perceptual-auditory evaluation and acoustic analysis, and vocal self-assessment.

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
Analyze the effect of semi-occluded vocal tract exercise, with high resistance tube, on the velopharyngeal mechanism
Time Frame: one month
Patients were submitted to evaluation of the VPS (velopharyngeal sphincter) region before and after the speech therapy. Patients were sitting in the examination chair, facing the examiner, throughout the entire procedure. The otorhinolaryngologist framed the image of the VPS and tried to maintain the optic fiber positioned at this site while those being evaluated performed selected sentences.
one month

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
Changes on speech after semi-occluded vocal tract exercise in cleft palate.
Time Frame: one month
To measure this outcome, samples of the participant's speech were recorded before and after the exercise with semi-occluded vocal tract (SOVTE). The vocal samples were randomly presented to three experients judges, voice specialists. They analyzed the samples and consensually completed the protocol of perceptual-auditory evaluation.
