Background Multisensor fitness trackers offer the ability to longitudinally estimate sleep
quality in a home environment with the potential to outperform traditional actigraphy. To …

Background Wearable sleep monitors are of high interest to consumers and researchers
because of their ability to provide estimation of sleep patterns in free-living conditions in a …

Study Objectives: Consumer home sleep trackers provide a great opportunity for longitudinal
objective sleep monitoring. Nonwearable sleep devices cause little to no disruption in the …

Polysomnography (PSG) is the “gold standard” for monitoring sleep. Alternatives to PSG are
of interest for clinical, research, and personal use. Wrist-worn actigraph devices have been …

We compared performance in deriving sleep variables by both Fitbit Charge 2™, which
couples body movement (accelerometry) and heart rate variability (HRV) in combination with …

Abstract Study Objectives Consumer sleep-tracking devices are widely used and becoming
more technologically advanced, creating strong interest from researchers and clinicians for …

Study Objectives: Consumer wearable devices may be a helpful method of assessing sleep,
but validation is required for their use in clinical practice. Our aim was to validate two models …

Abstract Study Objectives Multisensor wearable consumer devices allowing the collection of
multiple data sources, such as heart rate and motion, for the evaluation of sleep in the home …

For the last 40 years, actigraphy or wearable accelerometry has provided an objective, low-
burden and ecologically valid approach to assess real-world sleep and circadian patterns …

Purpose The commercialization of sleep activity tracking devices has made it possible to
manage sleep quality at home. However, it is necessary to verify the reliability and accuracy …
