Study Summary

The objective of this study is to collect data comparing the Zensorium Biosensing Wearable Device (zBWD) to polysomnography (PSG) in individuals with Sleep-Wake Disorders. zBWD is similar to other wearable devices (e.g., fitbit and apple watch) that use an optical light sensor and Tri-axis Accelerometer to record steps, activity, sleep/awake states, sleep staging, and statistical variation of pulse pressure to track stress. Specifically, it is designed to report sleep duration, non-rapid eye movement (NREM) and REM sleep duration. However, zBWD has not been validated against PSG for sleep tracking in healthy controls or in individuals with sleep-wake disorders.

Primary Outcome

A full clinical overnight polysomnography (PSG) study will be performed 7 - 10 days following visit 1. The subject will have EEG, EMG, EOG, and ECG electrodes, an adhesive body position sensor placed in standard locations. This equipment is standard for diagnostic PSG. The variables of interest from the PSG are stages of sleep as indicated by PSG including % rapid eye movement (REM; amount of time in REM sleep/Total sleep time) and % non-REM (amount of time in non-REM sleep/Total sleep time)
