Effect of Transcutaneous Electrical Stimulation on Polysomnographic Parameters in Patients With Obstructive Sleep Apnea

* The aim of this study is to assess the impact of transcutaneous electrical stimulation on polysomnographic findings in obstructive sleep apnea patients. * The hypothesis of the present study is that nocturnal delivery of transcutaneous electrical stimulation of the pharyngeal dilators, in particular the genioglossus, may help in treating the functional loss of the neuromuscular tone with sleep onset to keep the Upper airway patent during sleep which would reduce the severity of OSA as measured by the apnea-hypopnea-index (AHI), so representing an alternative and better-tolerated approach compared to usual care with CPAP.
