Virtual Performance-Enhancing Reality (ViPER) for robot-assisted gait training

Abstract

Robotic rehabilitation devices become increasingly popular in research and clinical use. One drawback of these devices is the reduced physical interaction between the therapist and the patient compared to manual training. Because of this lack, the device has to assess the patient's movements and display this assessment to the patient to give biofeedback, deliver instructions and increase motivation. This paper describes the design and implementation of an immersive virtual environment for robot-assisted gait training that delivers feedback and increases motivation. The subject can navigate through exchangeable virtual rooms and locations by modulating his or her performance of the left and right leg. Preliminary tests show usability with control subjects. Clinical tests are still required to show applicability in the clinical routine and to test for therapeutic efficacy
