Clinical Research Directory

Inclusion Criteria: 1. Adult males and females between the ages of 19 and 60 who do not fall under the exclusion criteria as study subjects 2. Patients with obstructive sleep apnea syndrome confirmed by polysomnography 3. Those who voluntarily consented to the clinical trial 4. Patients with sleep apnea with moderate or higher apnea hypopnea - Exclusion Criteria: 1. In case of refusal of inspection 2. Patients who do not agree 3. When instructions cannot be performed due to dementia, mental illness, etc. 4. Patients with sleep apnea due to respiratory failure or cervical spine surgery 5. In case of central nervous system abnormalities such as stroke 6. Pregnant and lactating women 7. Patients who cannot apply the electrical stimulation treatment device due to allergy to electrical stimulation pad (allergic reaction to chemical substances such as silicone, polypropylene, polyethylene, etc.), hypersensitivity reaction, etc. 8. Patients with severe regurgitation during electrical stimulation application 9. Others who have comorbidities (e.g., epilepsy, malignant tumors, severe renal/liver/pulmonary diseases, blood coagulation abnormalities, use of anticoagulants, phlebitis, thermophlebitis, etc.) 10. Those who are judged by other researchers to be unsuitable for this clinical trial (e.g., patients with infectious diseases, those who have inflammation or wounds on the skin at the site of electrical stimulation, and those who believe that electrical stimulation can cause abnormalities in the body regardless of disease) judged person) 11. Those who have been diagnosed with a disease that cannot be stimulated i. In patients with peripheral neuropathy (ex. Guillain-Barré syndrome), the electric stimulator does not induce muscle contraction, so it is ineffective. ii. Patients with congenital myopathy and amyotrophic lateral sclerosis do not receive help because muscle contraction is not induced. 12. Patients with sleep apnea due to pharyngeal muscle weakness or abnormal muscle contraction pattern 13. Persons with pacemakers and other internal electrical stimulators 14. Patients with a history of surgery in the area where the medical device is applied, or in the upper respiratory tract or surrounding area 15. Structural diseases such as 'tonsil hypertrophy' and 'soft palate' that can cause 'obstructive sleep apnea' (examined by physical examination)
