Experimental study of non-invasive percutaneous electrical stimulator for treatment of obstructive sleep apnea syndrome and its clinical effect / 生物医学工程学杂志

ABSTRACT

To study the stimulation of the genioglossus with percutaneous biphasic current pulses as a new therapeutical method to treat the obstructive sleep apnea syndrome (OSAS), polysomnography (PSG) was used to synchronously monitor the patient. When OSAS was occurring, the stimulation with the optimal parameter was given in time to make the tongue move forward, the glossopharyngeal airway dilated, the resistance of the upper respiratory tract reduced, the hypoxia at night to be improved and the sleeping structure to be ameliorated because of the function of the dilated muscle of the upper airway. The results of the clinical therapeutic effect indicated that 17 of 22 patients with OSAS had cured effects, 2 of whom improved and 3 of whom were without effect. The effective rate was 77.27%. It is preliminarily proved that this is a new method in the treatment of patients suffered from OSAS.
