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 …

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

To assess the use of actigraphy in evaluating insomnia, 36 patients with a serious complaint
of insomnia slept 3 nights each in the laboratory, where the usual polysomnograms (PSGs) …

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 …

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 …

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

In the past decades, actigraphy has emerged as a promising, cost‐effective, and easy‐to‐
use tool for ambulatory sleep recording. Polysomnography (PSG) validation studies showed …

To record sleep, actigraph devices are worn on the wrist and record movements that can be
used to estimate sleep parameters with specialized algorithms in computer software …

Measures derived from the wrist actigraph have been found to correlate highly with EEG
measures of normal sleep. Although the actigraph has been used to study normal sleep, few …

Objective: The present study explores the clinical utility and sensitivity of actigraphy as an
outcome measure in the treatment of chronic insomnia. Design: Following a screening …
