Indian Journal of Sleep Medicine, 2007 Actigraphy is a methodology for recording and analyzing activity (movement) from small, computerized devices worn on the body. Published reports on the reliability and validity of actigraph measures, although not comprehensive, generally indicate that sleep estimated by scoring algorithms is relatively consistent with PSG-scored sleep for normal ...

A comparison of actigraphy and sleep diaries for infants’ sleep behavior
Frontiers in Psychiatry, 2015 Detecting the effectiveness of behavioral interventions to reduce infant night waking requires valid sleep measures. Although viewed as an objective measure, actigraphy has overestimated night waking.

Comparison Between Actigraphy Records and Parental Reports of Child's Sleep
Frontiers in Pediatrics, 2020 Given the impact of sleep in several domains of a child's development, the comparison between actigraphy and parental questionnaires is of great importance in preschool-aged children, an understudied group.

Wrist Actigraphy in Insomnia [PDF]
Sleep, 1992 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) were obtained as well as actigraphic assessments of their sleep. Patients also wore actigraphs for 7 days at home, were extensively interviewed and filled out psychometric ...

Actigraphy: Analyzing patient movement [PDF]
Heart & Lung, 2011 Actigraphic data during simulated participant movements were evaluated to differentiate among patient behavior states.Arm and leg actigraphic data were collected on 30 volunteers who simulated 3 behavioral states (calm, restless, agitated) for 10 minutes; counts of observed participant movements (head, torso, extremities) were documented.The mean age ...
