Nightly Wearable Monitoring During Home-Based Submental Electrical Stimulation for Obstructive Sleep Apnea
Clinical Testing of a Physiological Signal Detection, Recognition and Feedback System for Obstructive Sleep Apnea: Home-Based Submental Transcutaneous Neuromuscular Electrical Stimulation With Nightly Ring-Type Monitoring
This single-arm pilot study evaluates the feasibility of nightly wearable monitoring with a ring-type sleep monitor during a 4-week home-based program of submental transcutaneous neuromuscular electrical stimulation in adults with obstructive sleep apnea, and describes changes in the ring-derived apnea-hypopnea index, sleep continuity, STOP-Bang score and upper-airway anatomy on CT before and after training.

Eksperimentel: Submental NMES with nightly ring monitoring
Adults with obstructive sleep apnea perform home-based submental transcutaneous neuromuscular electrical stimulation (30 minutes every evening for 28 consecutive nights) and wear a ring-type sleep monitor every night during and after training. |
Submental transcutaneous neuromuscular electrical stimulation with the RS-18 wireless low-frequency stimulator (Jie-Mai Medical Technology; TFDA license 007859; off-label use). Biphasic symmetrical pulses, 250 us, 30-100 Hz program, intensity self-titrated to a strong but comfortable contraction. One 30-minute session every evening before bedtime for 28 consecutive nights at home, after supervised instruction. A ring-type wearable sleep monitor (Belun Ring BLS-100) worn on the finger every night during the 4-week training period to record pulse oximetry, heart rate and accelerometry signals for ring-derived apnea-hypopnea index, oxygen desaturation index and sleep parameters. Used for monitoring only; no therapeutic function. |
