Monitoring of movement, especially during testing to assess sleep disorders.

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).

Participants completed the actigraphy tracking between 2010 and 2013 and were followed until 2016 and 2017.
At night, participants wore actigraphy monitors - wristwatch-like devices that measure movement - to help determine their "sleep efficiency," or the amount of time in bed spent sleeping soundly.
We admitted eligible participants to the hospital with blunt TBI confirmed by computerized tomography of the head, who had a Glasgow Coma Scale (GCS) score between 3 and 11 (severe to moderate brain injury) (22) on admission to the emergency department, who were 18 years or older, who were less than 24 hours on the neuroscience unit at the time of enrollment, and who had a Rancho Los Amigos (RLA) cognitive functioning score of 5 or greater (to include participants who could meaningfully contribute to the assessment of rest/activity with wrist actigraphy).
