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).

Comparison of Actiwatch activity monitor and Children's Activity Rating Scale in children.
As part of a research study, the patients' activity levels were measured using a wristwatch-like device called an actiwatch.
After 3 days, 20 patients were told about the discrepancy between the data from the activity monitor and their subjective estimates of sleep time and were taught to read the Actiwatch themselves.
The actiwatch showed I wasn't going to bed or getting up at regular times and, without realising it, I was having little naps during the day.

Royal Philips Electronics has introduced the Actiwatch 2 and Actiwatch Spectrum ambulatory actigraphy systems.
Actigraphy (Actiwatch AW4, Cambridge Neurotechnology Ltd; Cambridgeshire, United Kingdom, and Actiwatch L, Philips Respironics; Andover, Massachusetts) is a small, wrist watch-sized activity monitor that can register and quantify physical activity.
The Actiwatch actigraphy system, from Respironics/Mini Mitter, enables you to record the sleep/wake patterns, light exposure and subjective scores from your sleep-disordered patients for weeks at a time.
