Gait analysis is presently a common and useful tool for both biomechanical research andclinical practice. A lot of studies have developed multi-segment foot models in order tocharacterize foot kinematics. However, very few studies deal with dynamic analysis and novalidation has yet been done. The present study proposes a multi-segment foot model thatallows assessment of movements and mechanical actions within the foot.The instrumentation consists in a Motion Analysis® System with eight Eagle® cameras andtwo Bertec® forceplates. One RsScan® baropodometric plate is also used. Ten healthypeople are involved in this study. For each subject, ten gait trials are collected combiningkinematic, dynamic and baropodometric information. An original method of external actionsdistribution based on Coulomb’s laws will be used for inverse dynamics computation.The results are consistent with literature data and additional information (joint angles andjoint moments) is available with the present study. Future works involving more subjects willprovide the statistical analysis required to assess the detection of pathologic cases.
