抄録: As a method of the study of the gait, there has been the measurement of the floor reaction by the force plate. But it is not enough to know the accurate behavior during gait by the present instrument. Then the purpose of this study is to develop a new force plate and to get many informations concerning gait. The new force plate is supported by twelve combinations ball anb bar with strain gauges sticked on the latter. Therefore, it is able to measure various floor reactions simultaneously: normal compression, shear forces 'of antero-posterior and transverse direction, and torsion. Furthermore, it is the characteristics of the new instrument that the reaction forces are able to be combined each other and a locus of the resultant force draws an intuitive diagram, a loop, on the Braun tube. Six kind loops were obtained as combination of two from four reaction forces. Now we define these loops α, β, γ, ξ, ηand ζ diagram; For example, α diagram is the loop of combination of normal compression and antero-posterior shear force. Among them, it became clear that α diagram was the most important one and its characteristics was indicated as the inverted heart pattern, which was affcted and deformed easily by pitch and step width of gait. By use of α diagram it is possible to distinguish obviously the abnormal gait from the normal then it may be used as assistant of diagnosis and the rehabilitation. Another diagrams indicate less characteristics compared with α diagram, but also will be referred when making the artificial leg.
