What does the "Worn on Wrist" option do in the Scoring tab?

Defining the "Worn on Wrist" Option

The "Worn on Wrist" option allows users to tell ActiLife that the device was worn on the wrist and that the calculations in Scoring should be scaled appropriately.  At the time of this writing, there are no validation studies available that illustrate how to properly scale wrist-worn devices to yield kCal information. Waist-worn kCal calculations are still the defacto standard and research studies have proven the reliability. That said, ActiGraph applies the following piece-wise scaling to wrist-worn devices based on internal research and development:

The resultant counts are used to calculate kCals and Cut Points in the Scoring tab.
