A knowledge of the function of the foot is essential for an understanding of the mechanics of gait. In particular it is necessary to measure the forces, and their directions, between the foot and the ground. Miniature shoe borne load cells were used to measure the centre of foot pressure of a normal subject, a below knee amputee and a polio patient. An(More)
A finite element model of a complete vertebra has been formulated. It is used to simulate the laminectomy and Harrington rod procedures. The results indicate that high tensile stresses occurred on the affected side in the region of the pars interarticularis after laminectomy. High tensile stresses near the pars interarticularis and at the posterior junction(More)
Evidence indicating that comparison of a particular animal trace with a population average is an insufficient test of the health of a limb is presented. The methodology involves representing each of three recorded force components (vertical, lateral, and transverse) as a Fourier-Legendre series; the coefficients in the series represent the trace. A history(More)
A finite element model of a complete vertebra has been developed. The response of the loads applied to the model nodes were correlated with the experimentally measured pressures on the vertebral endplate. Model results were also validated against experimental data and were found to have a reasonably good correlation with measured strains. The model(More)
Miniature triaxial shoe-borne load cells are used to analyze the normal and a below knee amputee's gait. The gait of an amputee is studied from first step on a temporary pylon to a final "normal" gait on a permanent prosthesis. The amputee's gait is compared to that of the normal subject. The load cells are an effective method of analyzing normal and(More)
