Clinical Trial of a Rehabilitation Device Based on Electrostimulation for Obstructive Sleep Apnoea

Resumen breve

The aim of this study is to evaluate in a clinical trial a rehabilitation device for patients with obstructive sleep apnoea (OSA) based on oropharyngeal electrical stimulation, which strengthens the dilating muscles of the upper airway, improves mechanical laryngopharyngeal sensitivity and improves OSA. Furthermore, to perform experimental electrotherapy, nasoendoscopy, polygraphy and polysomnography tests with the device in order to calculate thresholds of functional and sensory intensities on the dilating muscles of the upper airway in patients with OSA. These tests also include the detection of signals that measure breathing events during sleep in patients with OSA in order to use them in the control mechanisms of the electrostimulation device. Assess the effects and safety of the device in a group of five healthy volunteers for preliminary results. Finally, to evaluate in a small group of patients with OSA the device capacity to stimulate the upper-airway dilating muscles and to reduce the Apnea-Hypopnea Index (AHI) and oxygen desaturation indices when the electrostimulation device is used over a medium-term period (eight weeks) with morning and evening therapy sessions.
