In this paper, dynamic analyses of normal walking of men are performed by measuring the foot pressure distributions. The measuring system is a sensing system of piezoelectric ceramics that was previously proposed by the authors. The sensor part of this system has 16×32 measuring points and the measuring area is 174mm×352mm, sufficient to measure foot pressure distributions of men. A microcomputer system is also used to analyze the numerous measured datums, and contour lines of foot pressure distribution and its related information are drawn on the display. By using this system, the dynamic change in foot pressure of standing and walking typical men are measured under the conditions of open or closed eyes, load or noload, and various walking speeds. From the results, the dynamic behavior of normal walking of men is discussed.
