Abstract

This study aimed to quantify the effect of combining the measurements from force plates when a subject’s foot comes in contact with more than one force plate. A 3-Dimensional Gait Analysis (3DGA) was performed on a subject walking barefoot. Ten gait trials (good both) were captured where both subject’s feet hit a single force plate. Then 20 gait trials (two force plates) were captured where either the right or left subject’s foot was in contact with two force plates at a time. Kinematics were computed with VICON1 Plugin Gait and kinetics with a BodyLanguage1 (VICON, Oxford, UK) model that allowed the combination of force plate measurements. The kinetics traces from both sets of data were compared using variance component analysis. Results suggest that effects of how the moments were calculated were at most a third of those arising from stride to stride variability. This suggests that development of automated systems for determining foot contact coupled with arrays of more and smaller force plates than are commonly used might be useful to ensure the capture of good quality kinetic data in a wide range of patients.
