Wearable fitness-tracker devices are becoming increasingly available. We evaluated the
agreement between Jawbone UP and polysomnography (PSG) in assessing sleep in a …

Study Objectives: Wearable devices, monitoring sleep stages and heart rate (HR), bring the
potential for longitudinal sleep monitoring in patients with neurodegenerative diseases …

Study Objectives: To evaluate the ability of actigraphy compared to polysomnography (PSG)
to detect wakefulness in subjects submitted to 3 sleep conditions with different amounts of …

Study Objectives: To determine the accuracy of early and newer versions of a nonwearable
sleep tracking device relative to polysomnography and actigraphy, under conditions of …

BACKGROUND: Actigraphy has become an important tool in sleep research, however, most
actigraphic models have had little evaluation of their sleep scoring software. Some reports …

Background Actigraphs are wrist-worn devices that record tri-axial accelerometry data used
clinically and in research studies. The expense of research-grade actigraphs, however, limit …

Study Objectives: To assess the sleep detection and staging validity of a non-contact,
commercially available bedside bio-motion sensing device (S+, ResMed) and evaluate the …

Background: Despite being the gold-standard method for objectively assessing sleep,
polysomnography (PSG) faces several limitations as it is expensive, time-consuming, and …

Study Objectives: Actigraphy is generally compared to polysomnography (PSG), which has
been considered the gold standard for sleep studies. The objective of the present study was …

Study objectives Sleep and physical activity are important contributors to many aspects of
health. Obtaining accurate, objective measures of both behaviours is critical to health …
