L'actimétrie en pratique clinique

Actigraphy is a method used to study sleep-wake patterns and circadien rhythms by assessing movement most commonly of the wrist. It is a reliable and valid for detecting sleep in normal, healthy populations, but less reliable for detecting disturbed sleep. Although actigraphy is not indicated for the diagnosis, assessment, or management of any of the sleep disorders, it may serve as a useful adjunct to routine clinical evaluation of insomnia, circadian-rhythm disorder, and excessive sleepiness.
