A comparison between positional therapy and continuous positive airway pressure therapy for positional obstructive sleep apnoea..

This study is comparing two treatments for positional obstructive sleep apnoea (pOSA) — a type of sleep apnoea where breathing problems mainly occur when sleeping on your back. The two treatments are CPAP (a mask that delivers continuous airflow to keep the airway open) and a vibrating wearable device worn at the back of the neck (called NightShift) that gently nudges you when you roll onto your back. Adults aged 18–65 with mild to moderate positional sleep apnoea confirmed by a sleep study, and who feel excessively sleepy during the day, will be randomly assigned to try each treatment for 8 weeks before switching to the other. The main measure is how sleepy participants feel (using the Epworth Sleepiness Scale), along with cognitive tests, sleep quality, and mood. You may be eligible if you are between 18 and 65, have been diagnosed with positional OSA on a sleep study, feel sleepy during the day, and have not previously used CPAP. People who are pregnant, work night shifts, drink heavily, have significant neurological or psychiatric conditions, or have severe sleep apnoea requiring urgent CPAP treatment cannot participate. This study aims to determine which approach works better for this specific group of sleep apnoea patients.
