Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The protocol is designed to first evaluate the accuracy of supine vs. non-supine detection in 15 subjects (hereafter referred to as study 1). In study 2, patients who had completed a baseline polysomnography (PSG) with a minimum of four hours of sleep time were to wear the Night Shift for two nights without feedback to confirm their willingness to continue with the study, followed by 28 nights of vibro-tactile position therapy. A follow-up PSG was to be conducted as soon as possible to the completion of the 28-nights of treatment. During enrollment subjects were to complete pre-treatment questionnaires designed to measure daytime sleepiness, insomnia severity, depression, anxiety, and quality of life. The same instruments were completed post-treatment on the morning after the 28th night of treatment. Subjects completed daily logs to confirm device utilization and identify potential non-device related factors that could influence study completion.

* have an overall Apnea-Hypopnea Index (AHI) \> 10 and hypopneas requiring \>3% oxygen desaturation,
* having a non-supine Apnea-Hypopnea Index (AHI) \< 15 if Continuous Positive Airway Pressure has not been attempted,
* have a overall AHI divided by the non-supine AHI \> 1.5,
* had an Epworth Sleepiness Score of 5 or more at the time of diagnosis and at the start of therapy,
