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 …

Actigraphy offers a low-cost alternative to conventional polysomnography (PSG) for
screening of sleep-wake patterns. Effective use of actigraphy signals requires reliable …

This study determined if using alternative sleep onset (SO) definitions impacted
accelerometer-derived sleep estimates compared with polysomnography (PSG). Nineteen …

The concurrent usage of actigraphy and heart rate variability (HRV) for sleep efficiency
quantification is still matter of investigation. This study compared chest (CACT) and wrist …

The multidimensional sleep health framework emphasizes that sleep can be characterized
across several domains, with implications for developing novel sleep treatments and …

Background The current gold standard for measuring sleep is polysomnography (PSG), but
it can be obtrusive and costly. Actigraphy is a relatively low-cost and unobtrusive alternative …

Purpose This paper aims to compare the absolute performance of three noncontact sleep
measurement devices for measuring sleep parameters in normal subjects against …

Actigraphy, a method for inferring sleep/wake patterns based on movement data gathered
using actigraphs, is increasingly used in population-based epidemiologic studies because …

Aims Evaluate the performance of 6 wearable sleep trackers across 4 classes (EEG-based
headband, research-grade actigraphy, iteratively improved consumer tracker, low-cost …
