MotionWatch 8 Wrist Actimetry Data Analysis: from ambulatory recording to real life monitoring

On the National Sleep Research Resource (NSRR) platform, there’s a year’s worth in real-life wrist actigraphy data using a Motionwatch8. The data analysis suggested in this paper reveals a data structure that allows the design of parameters to be used in real life monitoring and may drive the developments of devices. The analysis is totally data driven and connects in a quantitative way the wrist movements (time base seconds) to the circadian rhythms (time base days). A simple example of parameters is described
