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...

Effects of liquid stimuli on dual-axis swallowing accelerometry signals in a healthy population
liquid stimuli dual-axis accelerometry signals a healthy population
2010/2/25
Dual-axis swallowing accelerometry has recently been proposed as a tool for non-invasive analysis of swallowing function. Although swallowing is known to be physiologically modifiable by the type of f...
