In this paper a model is proposed to evaluate individually the normalized fatigue at the joint level. More specifically our model distinguishes the two antagonist muscle groups acting for each degree of freedom (in short dof). The fatigue model parameters are normalized torques, joint strength and the maximum holding time that a posture can be maintained. Fatigue evolution is predicted taking into account how these parameters evolve over time. Fatigue levels can be exploited by a posture control algorithm.
