Modeling of the human gait by means of dynamic software and inverse kinematics: An approach for design of prosthesis

model of the human body that was articulated by changing measurement based on a previous parameter. The Solid Edge V14 was used in this work and the model can be fitted to any physical body by using two parameters of simple inspection like height and body muscle. The model was provided with cinematic data about regular human gait that was obtained in a movement analysis laboratory which uses video graphic computers systems that were developed by the IBV (Intituto de Biomec~nica de Valencia, Spain). This data relates the angular movement of three joints of the limbs involved in the locomotion process (hip, knee, ankle) with the time and percentage of the gait cycle. The dynamic results that were obtained in the simulator (MSC Dynamic Designer Motion Pro) were articular moments in three dimensions (sagittal, coronal, transverse) about the joints mentioned above in both left and right legs. These results were put against with the ones obtained by the video graphic system (IBV) in order to support our model and the correlation was closed and consistent. So, the research demonstrates the possibility to make a model of the human body by using engineering software. Furthermore, it becomes a useful diagnosis tool that is trustful and could be used as a source of information to redesign personal prosthesis or orthesis.
