Monitoring of movement, especially during testing to assess sleep disorders.
[L. actus, action, + -graphy]

actigraphy

(ak-tig′ră-fē) [acti(vity) + -graphy]
The monitoring of body movements with a small device usually attached to the wrist or foot, used in sleep medicine (and sometimes in anesthesia or critical care medicine) to determine whether and how well a person is resting or sleeping. In sleep medicine, actigraphy can aid in the diagnosis of insomnia, obstructive sleep apnea, and periodic limb movements. It is used in anesthesia to determine depth of sedation (e.g., during recovery from surgery).

Their sleep was assessed via actigraphy measurements taken over 5 consecutive nights, keeping a sleep diary, and answering questionnaires, including the Epworth Sleepiness Scale, at three time points: prior to randomization, 8 weeks into the trial, and finally 1 week after the study ended.
2) Actigraphy is a non-invasive method for measuring and assessing the circadian rhythm of sleep-wake patterns continuously over several weeks through a device worn on the wrist.
Large variation in prevalence of shorter sleep duration exists between studies, mainly due to: cultural variability; different study measures used, such as actigraphy, polysomnography, parent-completed sleep diaries, or parental report; and developmental stages of the examined populations.
Beyond the Raspberry Pi, there is a vast array of cutting-edge tools for monitoring external exposures, ranging from individual-level assessment with sensors, personal exposure monitors, imaging technologies, actigraphy meters, wristbands, smartphones, and data scraping algorithms to ecological-level assessments with satellite remote sensing, modeling, and geographical information systems.
Use of additional objective measures should also be considered to supplement the parent report, including actigraphy or polysomnography.
The relationship between parental report of sleep duration and objective sleep duration using actigraphy has been measured.
Sleep was measured by both self-report and actigraphy.
Subjective assessment of sleep is done in this study which is less reliable than objective method like actigraphy and polysomnography.
Relative to sleep times based on actigraphy measures, self-reported sleep duration tends to be overestimated and have poor internal validity.
The global sleep apnea diagnostic and therapeutic devices market segmentation is based on product types (diagnostic devices - actigraphy systems, polysomnography, respiratory polygraph, single channel screening devices (pulse oximeters), therapeutic devices - adaptive servo ventilation systems, airway clearance systems, positive airway pressure devices, oral appliances, oxygen devices).
