Abstract :
The effect of soft tissue movement on electrogoniometer measurements of human gait is evaluated. The study consists of two parts-a simplified finite-element analysis and a cinematographic analysis to compare the angles measured by the electrogoniometer to the actual angles between the tibia and femur during gait. The results of the finite-element analysis are reported along with a brief description of the cinematographic analysis. The finite-element model, although very simplified with respect to geometry and material properties, provides a qualitative and an approximate quantitative description of soft tissue movement relative to bone. The results offer promise for much better results from a more complex model
