Lavaste LBM, ENSAM, Paris, CERAH, Woippy INTRODUCTION Whereas a lot of study investigated the gait of individuals with trans-tibial amputation, a few authors carried out kinematic and dynamic analysis of the gait of trans-femoral amputee. Gait analysis is a tool useful to evaluate quantitatively the performance of prosthetic systems. In dynamic studies, the models used are rarely detailed. Van der Linden[1] and Dundass[2] precised their method. Both measured inertial characteristics of three prosthesis in order to personalize a model used in an inverse dynamic method. Whereas some 3D dynamic models have been validated to obtain ground reaction forces for asymptomatic subjects, we didn’t find such a validation for amputees. The aim of the study was to develop a dynamic model to calculate the external forces applied on the feet during gait for a sample of asymptomatic subjects and for a group of patients with transfemoral amputation. A preliminary validation of the model was realized comparing forces calculated using kinematic measures as input data with forces measured by force plates.
