VIRTUAL PROTOTYPING FOR AN MECHATRONICS DEVICE USED FOR MEDICAL REHABILITATION

Abstract

In this paper presents some CAD models and virtual prototypes for rehabilitation orthotic device designed to train stroke patients to correct knee hyperextension during stance and stiff-legged gait (defined as reduced knee flexion during swing). The knee brace provides variable damping controlled in ways that foster motor recovery in stroke patients. An electrical motor, and mechatronics control is used to facilitate knee flexion during stance by providing resistance to knee buckling. Furthermore, the knee brace is used to assist in knee control during swing to allow patients to achieve adequate knee flexion for toe clearance and adequate knee extension in preparation to heel strike. In this paper will be present the detailed design of the rehabilitation orthotic device, the first prototype and some graphics from virtual testing.
