Electromyographic activity at the base and tip of the tongue across sleep-wake states in rats.
Obstructive sleep apnea (OSA) patients have elevated tonic and phasic inspiratory activity in the genioglossus and other upper airway muscles during wakefulness; this protects their upper airway from collapse. In this group, sleep-related decrements of upper airway motor tone result in sleep-related upper airway obstructions. We previously reported that in the rat, a species widely used to stud...
متن کاملBreathing modes, body positions, and suprahyoid muscle activity.
AIM To determine (1) how electromyographic activities of the genioglossus and geniohyoid muscles can be differentiated, and (2) whether changes in breathing modes and body positions have effects on the genioglossus and geniohyoid muscle activities. METHOD Ten normal subjects participated in the study. Electromyographic activities of both the genioglossus and geniohyoid muscles were recorded d...
متن کاملGenioglossus and intrinsic electromyographic activities in impeded and unimpeded protrusion tasks.
Eight muscles invest the human tongue: four extrinsic muscles have external origins and insert into the tongue body and four intrinsic muscles originate and terminate within the tongue. Previously, we noted minimal activation of the genioglossus tongue muscle during impeded protrusion tasks (i.e., having subjects push the tongue against a force transducer), suggesting that other muscles play a ...
متن کاملAsynchrony of lingual muscle recruitment during sleep in obstructive sleep apnea.
Pharyngeal collapsibility during sleep increases primarily due to decline in dilator muscle activity. However, genioglossus EMG is known to increase during apneas and hypopneas, usually without reversing upper airway obstruction or inspiratory flow limitation. The present study was undertaken to test the hypothesis that intense activation of the genioglossus fails to prevent pharyngeal obstruct...
متن کاملEffect of changes in the breathing mode and body position on tongue pressure with respiratory-related oscillations.
The purpose of this study was to examine whether tongue pressure on the lingual surface of the mandibular incisors shows respiratory-related changes, with particular attention paid to its relationship to genioglossus electromyographic activity, and to determine the effect of changes in the mode of breathing and body position on tongue pressure. Tongue pressure was recorded with a miniature pres...
