Shock therapy for snorers? new device zaps airway muscles to stop sleep apnea

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Patients over 18 years of age with confirmed OSA (four with mild OSA, four with moderate OSA and four with severe OSA) who sign their informed consent to participate in the study. Exclusion Criteria: * Pregnancy * Basal polysomnography that does not meet validity criteria to be interpreted. * Anticoagulation (although not a contraindication for laryngopharyngeal sensory endoscopic testing, anticoagulation is an exclusion criterion for this study to maintain the lowest level of risk). * Haemorrhagic diathesis (to avoid risk of severe epistaxis during nasal endoscopy). * Glasgow scale less than 15 (to avoid confusion with sensory or motor laryngopharyngeal involvement due to neurological disease that compromises the state of consciousness). * Basal oxygen saturation by awake pulse oximetry below 88%. * Patients with more than 5% of the total apnoea events being of central origin. (to avoid including patients with central sleep apnoea in whom laryngopharyngeal electrostimulation would have no effect). * Inflammatory or infectious lesions on the face or neck * Skin hypersensitivity * Anaesthetic areas, burns, bruises or recent wounds in the area of electrical stimulation * Cardiac pacemakers or other telemetry-controlled devices, * History of maxillofacial or pharyngeal surgery. * Active cancer * Tumours of the laryngopharyngeal tract. * Significant mental and/or behavioural conditions or inability of the patient to cooperate during the examination/intervention. * Epilepsy * Central Nervous System (CNS) surgery in the last three months (to avoid confusion with muscle or sensory laryngopharyngeal compromise). * Brain trauma in the last three months (to avoid confusion with muscle or sensory laryngopharyngeal compromise). * Neurological sequelae of any cause compromising the head and neck muscles (to avoid confusion with muscle or sensory laryngopharyngeal compromise). * Underlying neuromuscular diseases affecting the head and neck muscles (to avoid confusion with muscle or sensory laryngopharyngeal involvement due to neuromuscular disease). * Chronic use of systemic corticosteroids at doses greater than or equal to 20 mg daily of prednisone or equivalent (to avoid confusion with corticosteroid myopathy that compromises the laryngopharyngeal region). * Bone prostheses or osteosynthesis (in polarized currents there is danger of chemical burn and bone resorption) * Acute febrile processes * Chronic decompensated diseases * Diseases in terminal states * Refusal to participate in the study.
