The model presents five union segments (legs, thighs and torso) moved by electrical motors. The movement equations, presented in matrix form, are based on Lagrange-Euler and simulated on Matlab. The data obtained represents the joint torques according to preset trajectories. The trajectories are taken from a gait cycle and the results are matched against those found on the bibliography. The simulation built in MatlabÒ, is a tool that allows a physiotherapist to evaluate behaviors from a subject, with motor disabilities on his lower limbs, who is wearing an exoskeleton.
