Sleep Disordered Breathing (SDB) is a spectrum of conditions spanning from Simple Snoring to Severe Sleep apnea. SDB has multiple underlying mechanisms. Some portion of patients have issues with upper airway dilator muscle control; and such patients may be amenable to upper airway muscle training exercises using neuromuscular stimulation techniques. The investigators and others have published on the topic of neuromyopathy in the upper airway, defining a subgroup of OSA patients who may be amenable to training exercises. Based on this background, the investigators seek to test the hypothesis that upper airway tongue muscle training using transoral surface neuromuscular electrical stimulation may have benefits to patients with Simple Snoring.
