Actigraphy
Purpose
monitoring human rest/activity cycles
Actigraphy is a non-invasive method[1] of monitoring human rest/activity cycles. A small actigraph unit, also called an actimetry sensor,[2] is worn for a week or more to measure gross motor activity. The unit is usually in a wristwatch-like package worn on the wrist. The movements the actigraph unit undergoes are continually recorded and some units also measure light exposure. The data can be later read to a computer and analysed offline; in some brands of sensors the data are transmitted and analysed in real time.
