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).

At 6 months, the SSR group had improved perceived sleep quality and fatigue, and improved sleep efficiency as measured by actigraphy.
Sleep apnea diagnostic devices such PSG, actigraphy systems, and pulse oximeters are used for the screening of sleep apnea, while positive airway pressure and oral appliances are used for sleep apnea therapy.
Recent studies using wrist actigraphy and polysomnography have confirmed that POTS patients have decreased sleep efficiency, increased nocturnal awakenings, and increased REM latency compared to controls (11, 15).
Actigraphy measures of sleep quality and quantity were taken at the beginning of the intervention, to establish baseline measures for participants, and 12 months after the intervention.
The children's nighttime sleep was monitored by actigraphy, which uses a wristwatch-like device to evaluate sleep by measuring movements.
Wrist actigraphy data were collected from the nurses to provide an objective measure of intensity.
As an example, a presentation on unintended weight loss was presented by students from each discipline (dental discussed denture fitting, counseling depression, physical therapy actigraphy, and nursing dietary concerns and medications).
Objective sleep data also were gathered by actigraphy over a 10-day period.
Currently, the technology best suited for objectively tracking relevant sleep parameters in the operational environment is wrist actigraphy.
