The aim of this study is to develop for the first time a foot raising device orthosis for hemiplegics (RFO). Our original idea is to take into account human mechanics as a whole, and not considering the pathological area, only. In fact the characteristic of the hemiplegics is muscles stiffness during walking inducing an incapacity to move fluently. For example, kinetics of the pathological legs shows for some subject's stiffness of the Rectus Femoris during toe-off and swing phases prohibiting knee flexion. The results obtained for this first prototype confirm the capability of the system to improve knee and ankle movement during different walking phases. The perspective is to develop and to test this prototype with several subjects.
