Improving repeatability of setting volume origin and coordinate system for 3D gait analysis

Highlights • We investigated the variability from replacement of different calibration objects. • New calibration object instigated consisting of 4 markers screwed into the floor. • Coronal plane joint moments were most affected by miscalibration. • New calibration object had least variation for sag...

Description
Summary:Highlights • We investigated the variability from replacement of different calibration objects. • New calibration object instigated consisting of 4 markers screwed into the floor. • Coronal plane joint moments were most affected by miscalibration. • New calibration object had least variation for sagittal and coronal joint moments.
