Abstract


Within this paper we focused on modelling the complete human gait cycle, for pathological conditions as axial deviations, by using a fully parametric 3D assembly designed based on the Skeleton Systems method. Data acquisition could be provided from gait cycle laboratories or research centers and through the parametric assembly we can easily generate the associated virtual 3D model of the lower limb assembly within the three main phases of the gait: the initial heel contact (the heel strike), the mid-stance and the propulsion phase (the push off), as well as all the intermediary positions. Such an approach is of high interest due to the fact that the obtained model could further be used for finite element analysis or biomechanical studies.
