Sleep/wake identification and sleep parameter estimates from Motionlogger Watch and
Actiwatch-64 actigraphs were compared to polysomnography (PSG). Following one night of …

Study objective: The lack of quantitative criteria for identifying insomnia using actigraphy
represents an unresolved limit for the use of actigraphy in a clinical setting. The current study …

Two validation studies were conducted to optimize the sleep-detection algorithm of the
Actillume. The first study used home recordings of postmenopausal women (age range: 51 …

Actigraphy has become a common method of measuring sleep due to its non-invasive, cost-
effective nature. An actigraph (Readiband™) that utilizes automatic scoring algorithms has …

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 …

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 …

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 …

Background: Self-report remains the most practical and cost-effective method for
epidemiologic sleep studies involving large population-based samples. Several validated …

Actigraphy has emerged as a valuable method for measuring natural sleep patterns;
however, it is unclear how many consecutive nights should be measured and what sleep …

Polysomnography (PSG) is the “gold standard” for monitoring sleep. Alternatives to PSG are
of interest for clinical, research, and personal use. Wrist-worn actigraph devices have been …
