Actiwatch System

Actiwatch Family of Ambulatory Actigraphy Devices: Actiwatches are small, rugged, actigraphy-based data loggers that record a digitally integrated measure of gross motor activity. Each model of Actiwatch actigraph is equipped with a highly sensitive accelerometer as well as the ability to record additional data channels. The Actiwatch Score, Actiwatch-2, and Actiwatch Spectrum use actigraphy principles to provide sleep schedule variability, sleep quantity and quality statistics and daytime activity patterns.  All three models collect reliable, objective data on sleep/wake patterns for multiple days in a subject’s ambulatory environment with the comfort and aesthetics of a standard wrist watch.
