Abstract:This report describes the work conducted during a six-month internship at Julius Wolff Institut (JWI), Charité - Universitätsmedizin Berlin. This internship is part of the master’s curriculum of Mechanical Engineering of the University of Twente. The prime focus of the study was to analyze the effect of restricted ankle movement in two planes (sagittal & frontal) compared to single-plane restriction (sagittal) by using passive and active supporting ankle braces, respectively. Patients with a history of sprained ankles were assessed first for their baseline physiological movement during walking and active tasks, such as a single-limb drop landing. Furthermore, patients were tested on an apparatus that will induce a sudden inversion on the ankle joint, to see how well the ankle can resist movement in the frontal plane. The entire test is repeated with either a passive or active-supporting ankle brace. Motion capture with VICON was used to assess the kinematics not only at the ankle but also at the knee. The study is not yet finished and results are expected early next year.
