Feasibility of a Tele-rehabilitation System with Corrective-Force

This paper proposes a tele-rehabilitation system based on virtual reality (VR) and haptic interaction technologies. The proposed system allows the therapist to remotely monitor the patient's rehabilitation exercise and provide force to correct the patient's movement if it is unexpected. The force is generated according to the force model defined at the server side. It is important for the therapist to know the magnitude of force applied on the patient as excessive force may harm the patient. Experiment results demonstrate that the proposed system is feasible and that the therapist can correct patient's movement effectively through providing force.
