Waking genioglossal electromyogram in sleep apnea patients versus normal controls (a neuromuscular compensatory mechanism).

Pharyngeal collapse in obstructive sleep apnea patients is likely a product of a sleep-related decrement in pharyngeal dilator muscle activity superimposed upon abnormal airway anatomy. We postulate that during wakefulness, increased pharyngeal dilator muscle activity in apnea patients compensates f... View More
