Sensor device measures

Sleep measures derived from sensor devices are collected in MAP. The specific device has changed over time but the data collected by each device can emulate the original Actical signals in order to calculate the same actigraphy metrics for analyses.

AX3: 2020-present
GENEActiv: 2018-2020
Actical: 2005-2018

See the Actigraphy category description for details on each device.

Transition probability - Activity to rest Actical sleep measure - Probability of transitioning from active state to rest state (MAP only)
Transition probability - Rest to activity Actical sleep measure - Probability of transitioning from rest state to active state (MAP only)
Interdaily stability Actical measure - Interdaily stability (MAP only)
Intradaily variability Actical measure - Intradaily variability (MAP only)

Sleep questionnaire
