Actigraphy

Actigraphy is a non-invasive technique used to assess cycles of activity and rest over several days to several weeks. Your doctor may ask you to wear an actigraph for a period of time to get an objective measurement of your sleep schedule. An actigraph is worn like a watch on the wrist of your non-dominant hand and measures activity through light and movement.

Actigraphy data can be very helpful for assessing circadian rhythm disorders such as advanced or delayed sleep phase disorder and insomnia.
