Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Recently, various electronic lifestyle activity monitoring devices (ELAM) are increasingly commercially available. However, the quality and reliability of the data from ELAM are unclear, compared with polysomnography (PSG), which is the gold-standard sleep assessment method. Thus, combining ELAM with PSG will validate ELAM and improve its clinical and research utilization. The investigators propose to conduct this study to validate ELAM device for sleep assessment. The investigators will compare Belun Ring data collection and overnight in-lab PSG measures of Sleep-Disordered Breathing (SDB) and sleep architecture in adults with obstructive sleep apnea (OSA) symptoms. The investigators propose to recruit a total of 40 participants with symptoms of OSA. The overall accuracy, sensitivity and specificity of Belun Ring to assess SDB and sleep architecture will be validated by using PSG analysis as a gold standard.
