Abstract : Workstations design has a direct impact on working conditions. Ergonomics takes an important place in the industry. Musculoskeletal disorders (MSD) appear more and more frequently as working diseases. The purpose of this thesis is the design of motion analysis tools of the upper extremity that can be used to improve the ergonomics of workstations and decrease the risks of MSD appearance. The main contributions presented in this thesis are: - A biomechanical model of the upper extremity based on functional anatomy ; - A complete processing chain, from motion capture to muscle forces estimation in an inverse dynamics approach; - The definition and the evaluation of additional constraints that can simulate the co-activation of the antagonism muscles ; - The presentation and the evaluation of an muscle forces computation method based on interpolation; - The definition and the evaluation of an ergonomic criterion usable to evaluate the painfulness of a motion.
