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

During the last decade actigraphy (activity-based monitoring) has become an essential tool
in sleep research and sleep medicine. The validity, reliability and limitations of actigraphy for …

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

Current evidence has shown that, overall, actigraphy is an excellent tool for unobtrusive
documentation of sleep/wake activity in normal individuals. However, a number of …

1.0 BACKGROUND ACTIGRAPHY HAS BEEN USED TO STUDY SLEEP/WAKE PATTERNS
FOR OVER 20 YEARS. The advantage of actigraphy over traditional polysomnography …

Abstract Study Objectives: While actigraphy is considered objective, the process of setting
rest intervals to calculate sleep variables is subjective. We sought to evaluate the …

Actigraphy is a method used to study sleep-wake patterns and circadian rhythms by
assessing movement, most commonly of the wrist. These evidence-based practice …

In recent years, wrist actigraphy has been scrutinized as a possible supplement to or even
replacement for other methods traditionally used to assess the sleep of clinical patients and …

Activity-based sleep-wake monitoring or actigraphy has gained a central role as a sleep
assessment tool in sleep medicine. It is used for sleep assessment in clinical sleep research …

Abstract Study Objectives: Because sleep and wakefulness differ from each other by the
amount of body movement, it has been claimed that the two states can be accurately …
