Abstract


The first objective of this paper is to develop the virtual model and physical prototype of a new exoskeleton, useful for the stabilization and rehabilitation of the human osteoarthritic knee (OA). The second objective is to validate the proposed exoskeleton using numerical and experimental results of the average exoskeleton cycle. An experimental study is provided to compare the amplitude and shape of mean cycles of knee flexion-extension angles of the exoskeleton, of a sample of eight healthy subjects, a sample of six patients with OA knees, before and three months after total knee replacement.
