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

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 …

Study Objectives: Total sleep time (TST), sleep efficiency (SE), sleep latency (SOL) and
wake after sleep onset (WASO) assessed by actigraphy gathered in 3 different modes were …

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) …

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 …

Objectives Actigraphy is widely used to estimate sleep–wake time, despite limited
information regarding the comparability of different devices and algorithms. We compared …

Abstract Study Objective: Actigraphy, a method of inferring sleep from the presence or
absence of wrist movement, has been well validated against polysomnography in trials with …

Wrist actigraphy is commonly used to measure sleep, and hip actigraphy is commonly used
to measure activity. It is unclear whether hip-based actigraphy can be used to measure …

Wrist actigraphy (ACT) may overestimate sleep and underestimate wake, and the agreement
may be lower in people with chronic conditions who often have poor sleep and low activity …

Abstract Study Objectives: Current actigraphic algorithms are relatively less accurate in
detecting sleep and wake in sleep apnea patients than in people without sleep apnea. In the …
