Dear Editor, Clinicians and researchers are increasingly interested in employing tracking
devices to measure activity and sleep, both of which are calculated via algorithms that use …

Background Wearable devices have tremendous potential for large-scale longitudinal
measurement of sleep, but their accuracy needs to be validated. We compared 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 …

Objectives: We validated actigraphy for detecting sleep and wakefulness versus
polysomnography (PSG). Design: Actigraphy and polysomnography were simultaneously …

Abstract Study Objectives: To evaluate the validity and reliability of 2 new models of
commercially available actigraphs compared to polysomnography for children and …

Abstract Study Objectives Wearable sleep technology has rapidly expanded across the
consumer market due to advances in technology and increased interest in personalized …

Objective To assess the agreement of sleep parameters measured by two actigraphs
(SOMNOwatch plus®, ActiGraph GT3X+®) at two different placements (wrist, hip) and of self …

Wrist actigraphy is employed increasingly in sleep research and clinical sleep medicine.
Critical evaluation of the performance of new actigraphs and software is needed. Actigraphic …

Sleep-tracking devices, particularly within the consumer sleep technology (CST) space, are
increasingly used in both research and clinical settings, providing new opportunities for …

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 …
