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).

Actiwatch Spectrum Plus (Phillips Respironics) actigraphs were used to assess wake bouts, total wake time, and sleep efficiency (percentage of time in bed spent asleep).
They also wore an Actiwatch, which assesses sleep/wake patterns.
Sleep quantity was assessed by means of an actigraph that was continuously worn around the non-dominant wrist and only detached during training or when being in contact with water (Actiwatch 2, Philips Respironics, Munysville, USA).
Actiwatch 2 (Philips Respironics) actigraphs were used to measure sleep.
Sleep parameters were assessed using an actigraph (Actiwatch, Respironics, Inc., Mini-Mitter, Bend, OR) and a data analysis software platform (Actiware, version 5.59.0015, 2010).
Therefore, in this study, the use of acupuncture for the add-on treatment of comorbid sleep disorders in a patient with chronic schizophrenia is investigated further by using both psychological-test and actiwatch data.
Physical activity was evaluated with the Actiwatch AW7 (Actiwatch AW7; CamNtech Ltd., Cambridge Neurotechnology, Cambridge, UK), which is a small (39 x 32 x 9) and light-weight (10.5 g) accelerometer that measures sleep-wake physical activity.
Objective sleep disturbances were measured by the Actiwatch Score actigraph (Philips Respironics, Andover, MA), which is a noninvasive method that uses internal motion sensors to capture patient movement data, represented as the number of accelerations per minute [38].

The ActiGraph (Actiwatch, AW64[R], Mini-Mitter Co Inc, Bend, OR, USA) was applied on the participant's non-dominant wrist (Figure 1), to be worn on the day prior to shift-work and on three consecutive days after shift-work to evaluate sleep duration and continuity as well as to obtain some information about daytime naps (10-12).
