Towards Uniform Accelerometry Analysis: A Standardization Methodology to Minimize Measurement Bias Due to Systematic Accelerometer Wear-Time Variation
Accelerometry wear-time variation data standardization
2015/5/22
Accelerometers are predominantly used to objectively measure the entire range of activity intensities – sedentary behaviour (SED), light physical activity (LPA) and moderate to vigorous physical activ...

Comparability of Measured Acceleration from Accelerometry-Based Activity Monitors
GENEACTIV ACTIGRAPH GT3X+ TIME DOMAIN FREQUENCY DOMAIN
2017/4/14
Background: Accelerometers that provide triaxial measured acceleration data are now available. However, equivalence of output between brands cannot be assumed and testing is necessary to determine whe...
