Design of a multi-functional system based on virtual reality for stroke rehabilitation

This paper presents a motor function rehabilitation system for the disabled with virtual reality. The design of the entire system is established on the SIGVerse virtual platform. The patient can complete the rehabilitation training immersed in a virtual environment. Firstly, the motion information of the patient is recognized by Kinect, and regenerated by the avatar in the virtual environment accurately. At the same time, the view of the avatar can be presented to the patient by HMD. Though this method, the patient can exposure to the virtual environment during the rehabilitation training, so that they can feel like their real and health motions in the virtual environment. Additionally, the EMG signals of the activated muscle are collected, and they can provide a feedback of contraction intensities of the muscle to the patient in real time. Moreover, we provide an electrical stimulation to the corresponding muscle. As a result, the patient can have the perception of muscle contractions.
