Rehabilitation system for disabled persons based on virtual reality

Abstract

The invention discloses a rehabilitation system for disabled persons based on virtual reality, which comprises a functional electrical simulation module, a motion capture module and a virtual reality module; wherein the motion capture module is respectively connected with the functional electrical simulation module and the virtual reality module. By stimulating the nerves and muscles of human body and simultaneously recording the limb movement after stimulation, the rehabilitation system for disabled persons based on virtual reality adjusts a functional electrical stimulation parameter through closed loop control, and presents the movement to a user by utilizing a virtual reality technology. For the reconstruction of limb movement function, the closed loop control is a more natural optimal control method which realizes the stationarity of limb movement and better conforms to human movement characteristics. Real-time visual feedback can effectively promote the reconstruction of limb movement function and improve the efficiency of rehabilitation training. The three-dimensional interactive immersing environment of the virtual reality can provide multi-mode feedback information such as visual feedback information, acoustic feedback information and the like of movement process and movement effect for patients, arouse and maintain the motivation of the patients for repetitive practice.

Description

technical field [0001] The invention relates to a rehabilitation device, in particular to a rehabilitation device combining virtual reality and functional electrical stimulation (FES). Background technique [0002] According to the results of the second national sample survey of disabled people in 2006, the number of disabled people in China has reached 82.96 million, accounting for 6.34% of the national population, of which 24.12 million are physically disabled, and 60% of disabled people need nursing care and rehabilitation training. At the same time, the data analysis report of the survey predicts that the growth of the number of disabled people will soon enter a period of rapid growth, and the disability rate will continue to rise. [0003] Functional electrical stimulation directly acts on paralyzed muscles, which can prevent muscle atrophy, enhance muscle strength, strengthen nerve impulses, promote limb blood circulation and nerve regeneration, and achieve the purpose...
