Article Synopsis
  • The study investigates the role of the genioglossus (GG) muscle in tongue movement during breathing, specifically focusing on the anterior fibers and their EMG activity during wakefulness and sleep.
  • Results showed that electrical stimulation of the anterior GG fibers caused tongue retraction, while the longitudinal fibers were responsible for protrusion.
  • The findings reveal distinct control mechanisms for the anterior GG compared to the protrusive fibers, suggesting that treatments for obstructive sleep apnea should avoid stimulating the retractor fibers of the GG.

Methods: This pragmatic open-label randomized-controlled trial evaluated 81 older adults hospitalized in an internal medicine ward and diagnosed with delirium.
