The present study was designed to identify possible asymmetries between feet in human walking. Foot loading patterns of the slow (1.11 m.s-1), normal (1.53 m.s-1) and fast (1.94 m.s-1) speeds were investigated on 12 healthy volunteers. 2-D ground reaction forces (GRF) were measured by a 10m long force platform and a data-acquisition system was used to record the plantar pressures. The plantar pressures were greater most of the areas of the foot sole when walking speed increased, bu decreased under the lateral forefoot and central part of the forefoot. Thus, the weight-bearing model shifts more to the medial edge of the forefoot at the higher walking speed. Gait patterns were symmetrical at the selected walking speeds, although bilateral comparison revealed asymmetries in the plantar pressure patterns under midfoot. The pressure distribution reflect these asymmetrical patterns more accurately than the GRFs.
