抄録: It is usually convenient to use the force plate method for the analysis of human walking, then many researches have been reported by this method. As these force plates have the sizes enough area of a foot, it is necessarily asked for some effort to step exactly on them. This state is not thought of the natural walking. Therefore, it might be desirable to use the large force plate having enough area to step even if the arbitrary walking. However, the research referred to it is rare and it is not clear about its characteristics also. The large force plate used, is supported at four points which are equipped with three load cells to measure the forces of x, y and z directions, which are foreward, right and downward respectively. The forces of z, x and y directions and the moment around z axis are inspected with dead weight, pull load through the correct load cell and couple forces of x and y directions, at many points of this plate. From these results, total value summerized each load cell is linear against the applied load or force at arbitrary point on the force plate. But each value itself is slightly different from the theoretical one. Generally, the coordinate of applied step force can be calculated with one of each load cell, and twist of ankle during walking is also gotten with forces, moment and coordinate. According to the procedure reported before, step force diagrams of x, y and z directions and twist of ankles, moreover, the locus of the center of gravity during walking on the large force plate are graphically displayedby the computer system.
