There are many prosthetic foot-ankle units with various functions. A postheist selects a prosthetic foot to match the life style and activity of each prosthetic user. One of the methods to evaluate the prosthetic foot function is the roll-over shape of foot-sole. This paper describes new method to get the rollover shape in walking. A measuring system is constructed from a six-component force transducer installed in upper position of the prosthetic foot and a three dimensional coordinates measuring device (Mac3D), and the roll-over shape while in walking is calculated. In this paper, we propose a new calculation method to get the locus of the fcp ( force contact point ), instead of the cop ( center of pressure ).
