Abstract: Electric stimulation method and system for treating Obstructive Sleep Apnea (OSA) Syndrome using an external actuator on the pharyngeal-laryngeal muscles. Using this actuator, the muscles involved receive an electric stimulus, with the aim of widening the muscular opening and attaining sufficient air flow to prevent the lack of air. Said stimulus only acts in the event of an apnea episode being detected, by means of analyzing sound patterns of the upper airways. Both detection and treatment arc self-regulatory, in order to adapt to the patient's morphology and the evolution of the condition or problem.
