Amputation Upper Rehabilitation System Based On Virtual Reality

Because of illness or accident causing serious injury so that patients have to take upper limb amputation. Unfortunately,patients must have an tremendous effect on psychological . Although, patients can install the EMG prosthetic hand to recover some daily function and improve self-care ability of life, in order to achieve flexible control of EMG prosthesis, it is particularly important with long-term training aiming for strengthening specific parts of the brain on the EMG signal before the installation of EMG prosthesis, which help patients to accurately control myoelectric prosthetic hand.Rehabilitation doctor have done a lot of works to help patients recovery, But due to objective conditions, currently there are many shortcomings at the training that for rehabilitation of patients with upper limb amputation. For instance: the training position is free, the training effect is not intuitive, and interesting training methods are lacked.In this paper a real-time electromyogram (EMG) pattern recognition based on virtual reality system for the upper limb rehabilitation is designed,In order to provide effective training for patients. a combination of AR and neural network technique for EMG pattern identification is adopted, and it can driver a specific person Realistic 3D model of the hand and upper limb, In the virtual reality environment, fingers can open and close, rotate the wrist, bent wrist, elbow and other training actions. It can greatly reduce the workload of medical staff after using VR, and it can also help patients to feel more favorable, continuously to help patients in the correct psychological suggestion and receive more encouragement, It improves the training efficiency and shortens the recovery period.
