Comparison of epoch and uniaxial versus triaxial accelerometers in the measurement of physical activity in preschool children : a validation study [PDF]

, 2012
The objectives of this Study were to explore whether triaxial is more accurate than uniaxial accelerometry and whether shorter sampling periods (epochs) are more accurate than longer epochs. Physical activity data from uniaxial and triaxial (RT3) devices
