User Compliance and Behavioral Adaptation Associated With Supine Avoidance Therapy

This study investigates behavioral adaptation to vibrotactile position-avoidance therapy during sleep in patients with obstructive sleep apnea (n =135) across 15 to 52 weeks. The overall compliance, based on nights used ≥ 4 hr, was 71%. Overall regular use, that is, ≥ 4 hr/night over 70% of nights, was 88%. Poor early compliance strongly predicted [...]

Assessment of a Neck-Based Treatment and Monitoring Device for Positional Obstructive Sleep Apnea

The objective of this study was to evaluated the accuracy and efficacy of a neck-worn device designed to limit supine sleep. The study included nightly measurements of snoring, sleep/wake, time supine, and the frequency and duration of feedback to monitor compliance. Thirty patients between ages 18 and 75 years, BMI ≤ 35 with an overall [...]

Capability of a neck worn device to measure sleep/wake, airway position, and differentiate benign snoring from obstructive sleep apnea

Abstract To evaluate the accuracy of a neck-worn device in measuring sleep/wake, detecting supine airway position, and using loud snoring to screen for obstructive sleep apnea. Study A included 20 subjects who wore the neck-device during polysomnography (PSG), with 31 records obtained from diagnostic and split-night studies. Study B included 24 community-based snorers studied in-home [...]

Sleep Profiler Automated Sleep Staging compared to Manual Scoring

Download Full Article The objective of this study was to investigate the accuracy of an automated sleep-staging algorithm that is based on a single bipolar EEG signal. Three raters each manually scored the polysomnographic records from 44 patients referred for sleep evaluation. The mean positive percent agreement across subjects and stages was 72.6%, approximately [...]

Retrospective cross-validation of automated sleep staging using electroocular recording in patients with and without sleep disordered breathing

Download Full Article Abstract: Alterations of sleep duration and architecture have been associated with increased morbidity and mortality, and specifically linked to chronic cardiovascular disease and psychiatric disorders, such as type 2 diabetes or depression. Measurement of sleep quality to assist in the diagnosis or treatment of these diseases is not routinely performed due [...]
