Summary
Hypoglossal nerve stimulation does not awaken patients from sleep after acclimation. A gradual acclimation period is crucial for patients to adjust to stimulation settings, preventing arousal.
Area of Science:
- Neuromodulation
- Sleep Medicine
- Medical Devices
Background:
- Obstructive sleep apnea (OSA) is a common disorder.
- Hypoglossal nerve stimulation (HNS) is an emerging treatment for OSA.
- Patient acclimation to HNS is not well understood.
Observation:
- A case report details a patient undergoing HNS therapy.
- The patient experienced tongue movement during sleep due to stimulation.
- No awakening occurred once the patient acclimated to the sensation.
Findings:
- Activated implanted devices for HNS do not awaken patients post-acclimation.
- A gradual acclimation period is essential for successful HNS therapy.
- Stimulation settings below the threshold of gross tongue movement aid acclimation.
Implications:
- HNS can be safely used in sleeping OSA patients.
- Acclimation protocols should be individualized.
- Further research into HNS acclimation is warranted.

Sensory receptors are specialized neurons that respond to specific types of external stimuli, initiating the process known as sensation. This occurs when sensory input, such as light entering the eye, is detected by these receptors, causing chemical changes in the cells of the retina. These cells then convert the sensory stimulus into action potentials that are transmitted to the central nervous system, a process termed transduction.

Animal organs and organ systems constantly adjust to internal and external changes through a process called homeostasis ("steady state"). Examples of these changes include regulation of the level of glucose or calcium in the blood or internal responses to external temperatures. Homeostasis requires maintaining an internal dynamic equilibrium:
