Non-invasive intraoral genioglossus myoelectric activity assessment method and system

Abstract

The invention discloses a non-invasive intraoral genioglossus muscle electromyographic activity evaluation method, comprising the following steps: S1, obtaining the subject's AHI index; S2, for the subject with AHI>15, respectively obtaining the ggEMG signal parameter value and the Pepi signal Parameter value: S3, according to the ggEMG signal parameter value and the Pepi signal parameter value, calculate the unit pressure EMG value R1 in the awake period, the unit pressure EMG value R2 in the early stage of sleep, and the minimum unit pressure EMG value in the N2 phase of apnea R3, N2 phase. Apnea maximum unit pressure EMG value R4, N2 stage nasopharyngeal airway implantation unit pressure EMG value R5, and calculate the mean value and R standard deviation of R1 to R5; S4, according to AHI index and R standard deviation two parameters, the intraoral genioglossus EMG activity of subjects with AHI>15 can be classified, and the functional factors related to the genioglossus muscle can be objectively evaluated in moderate-severe OSA subjects with AHI>15 , which is beneficial to provide an objective basis for the treatment of the cause. The invention also discloses a system for realizing the above evaluation method.

Description

technical field [0001] The invention relates to a non-invasive intraoral genioglossus muscle myoelectric activity evaluation method, and also relates to a system for realizing the above non-invasive intraoral genioglossus muscle myoelectric activity evaluation method. Background technique [0002] Obstructive sleep apnea (OSA) is a common sleep-disordered breathing disorder, which can cause a series of pathophysiological changes such as nocturnal hypoxia, hypercapnia, significant fluctuations in intrathoracic pressure, and disturbed sleep structure. A number of studies have confirmed that OSA is an independent risk factor for various chronic diseases such as hypertension, coronary heart disease, cerebrovascular disease, and diabetes. Not only that, OSA, as a high-risk predisposing factor of traffic accident, seriously threatens the life safety of motor vehicle drivers. At present, there is still no simple and effective treatment for OSA. The American Sleep Society has eval...

Problems solved by technology

However, there are few clinical assessments of functional factors related to nerve-upper airway dilator regulation, which may be one of the reasons for the current limited efficacy of OSA.
