  1. aGeneActiv measures the acceleration of movement at the wrist and provides the output as raw acceleration (milli-g, i.e. multiples of 0.00981 m/s2). With previous accelerometry monitors, raw acceleration data was converted into counts through a manufacturer-specific algorithm that wasn’t disclosed, preventing comparison between studies. The average acceleration for each child provides a measure of acceleration over the measurement period
