About this study

Official title: Non-invasive Reinforcement of the Upper Airway Dilator Muscles as an Alternative Approach to Treat Patients With Obstructive Sleep Apnea

This study will investigate the effectiveness of a simple and quick myofunctional reeducation protocol of the tongue in reducing the obstructive sleep apnea syndrome (OSAS) severity.

Read the detailed description

This is a randomized controlled study. Participants with moderate OSAS severity will be either allocated to receive a myofunctional reeducation protocol (study group) or a sham protocol (control group). Apnea-hypopnea index (AHI) will be measured before and at the end (6 weeks) of the protocol. Participants from the study group will follow an upper airway reinforcement regimen using the IOPI (Iowa Oral Performance Instrument) device over 6 weeks while participants from the control group will perform a sham reeducation protocol using an "EMT threshold" at minimal resistance.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • IOPIDevice

    IOPI is a portable device with a tongue bulb used to reinforce upper airway muscles.

  • EMT thresholdDevice

    EMT threshold is a small portable device producing a positive expiratory pressure when the patient is exhaling.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in AHI (apnea-hypopnea index) on polygraphy

    Evolution of the number of apnea-hypopnea events (AHI) over 6 weeks. The AHI value at discharge will be compared with the baseline value.

    Measured: Baseline and 6 weeks

Secondary outcomes (2)
  1. Change in tongue strength using the IOPI device

    Evolution of tongue strength over 6 weeks. Tongue strength will be measured by asking the participants to squeeze the tongue bulb of IOPI as much as possible over 3 seconds. Three trials are accepted and the best value will be recorded (Pmax). Pmax at discharge will be compared with Pmax at baseline.

    Measured: Baseline and 6 weeks

  2. Change in tongue endurance using the IOPI device

    Evolution of tongue endurance over 6 weeks. Tongue endurance will be measured by asking the participants to sustain a tongue pressure against the IOPI bulb at 50% of Pmax. Endurance will be assessed by measuring the holding duration of 50% of Pmax. Holding duration at discharge will be compared with the value at baseline.

    Measured: Baseline and 6 weeks

Questions about this trial

What is this clinical trial studying?

A study testing IOPI and EMT threshold in people with Obstructive Sleep Apnea Syndrome, run by Haute Ecole de Santé Vaud at 2 sites in Switzerland.

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 2 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: status not confirmed, as of the sponsor's last update on 28 Oct 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Olivier Contal, PhD (+41213168122, olivier.contal@hesav.ch), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in AHI (apnea-hypopnea index) on polygraphy (time frame: Baseline and 6 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 28 Oct 2019.
