Reproducibility of a triaxial seismic accelerometer (DynaPort).

Validation of the triaxial accelerometer for the evaluation of physical activity in Japanese patients with COPD.

OBJECTIVE The quantification of physical activity is useful for the management of chronic obstructive pulmonary disease (COPD) but has not been fully established yet. The DynaPort Activity Monitor(®) (DAM), a triaxial accelerometer is the only well validated accelerometer in Caucasians but it has not been validated in Japanese COPD patients. We initially evaluated the reproducibility of the DAM...

A Simple and Fast Method for Field Calibration of Triaxial Gyroscope by using Accelerometer

Validity of DynaPort GaitMonitor for assessment of spatiotemporal parameters in amputee gait.

Accelerometry can be used to objectively assess the walking ability of people with a lower-limb prosthesis inside and outside the laboratory setting. In this study, the validity of the DynaPort GaitMonitor software (McRoberts, The Hague, the Netherlands) for assessing spatiotemporal parameters of amputee gait was evaluated. Fourteen subjects with a lower-limb prosthesis walked on a straight lev...

Physical Activity in Hemodialysis Patients Measured by Triaxial Accelerometer

Different factors can contribute to a sedentary lifestyle among hemodialysis (HD) patients, including the period they spend on dialysis. The aim of this study was to evaluate characteristics of physical activities in daily life in this population by using an accurate triaxial accelerometer and to correlate these characteristics with physiological variables. Nineteen HD patients were evaluated u...

Estimating activity-related energy expenditure under sedentary conditions using a tri-axial seismic accelerometer.

Activity-related energy expenditure (AEE) is difficult to quantify, especially under sedentary conditions. Here, a model was developed using the detected type of physical activity (PA) and movement intensity (MI), based on a tri-axial seismic accelerometer (DynaPort MiniMod; McRoberts B.V., The Hague, the Netherlands), with energy expenditure for PA as a reference. The relation between AEE (J/m...
