基于虚拟现实的下肢主被动康复训练系统研究
Active and Passive Training System of Lower Limb Rehabilitation Based on Virtual Reality

针对传统下肢康复训练中病人参与度低、无法产生主动运动意图等问题,设计实现了基于虚拟现实的下肢康复训练系统。基于大脑镜像神经元和神经可塑性理论,利用Matlab和Labview等软件实现数据实时通信与反馈处理,结合虚拟现实场景建模和动画脚本编辑的方法,通过3D视觉和听觉等效果作用于患者神经中枢,形成信息传递的封闭回路,以实现对受损神经中枢的主被动协同刺激,激发大脑运动区镜像神经元,强化自主运动意图。研究结果表明,该系统能辅助患者完成主被动模式下的康复训练,并在训练中为患者提供深度虚拟环境的视觉交互,大大增强了康复训练中对受损神经中枢的刺激,提高了患者的训练效率和积极主动性。该技术在神经中枢损伤的康复领域有一定的应用前景。
Aiming at the problems such as low participation in the traditional lower limb rehabilitation training and being unable to produce the active movement intention, a lower limb rehabilitation training system based on virtual reality is designed. Following the theories of human brain mirror neurons and neural plasticity, real？？time data communication and feedback processing are realized with Matlab and Labview software. Combining with the method for virtual reality modeling and animation script editing and exerting effect on the patient central nervous system through 3D visual and auditory, a closed information transmission loop is constructed to achieve the active and passive synergistic stimulation of the damaged nerve center to stimulate the brain motor area of mirror neurons and to strengthen the independent movement intention. The results show that the system is able to assist patients to complete rehabilitation training of active and passive mode, and provides patients with the depth of the living environment of the virtual visual interaction, which greatly enhance the rehabilitation training for patients with damaged neural stimulation, and improve the training efficiency and positive initiative
