Interaction Design Of Sports Rehabilitation Equipment Based On MI-BCI

In recent years,the design and research of sports rehabilitation equipment has received continuous attention.In the 14 th Five-Year National Health Plan,it is emphasized to improve public health services,disease prevention and control,and medical treatment capabilities,improve the multi-level medical security system,and implement the party ’s health work policy in the new era.Comprehensively promote the construction of healthy China,implement the promotion and application of rehabilitation aids and intelligent aging technology.According to the latest global burden of disease research data,the number of patients with movement disorders caused by severe neurological deficits in China is increasing year by year.According to the summary report of China Stroke Prevention and Treatment Report 2020,the mortality rate of stroke-based brain neurological diseases has ranked first in China,accounting for one-third of the total number of disease deaths.At the same time,due to the continuous development and integration of computer science,a series of breakthroughs have been made in brain science research and medical research in China.The diagnosis,treatment and prevention technologies of brain diseases have become increasingly mature,and the application of brain-computer interface(BCI)technology in clinical and basic research of brain diseases has gradually increased.Motor Imagery braincomputer interface(MI-BCI)system collects human brain signals and converts them into signals that can be recognized and interpreted by computers,so as to realize the control of human motor function,sensory function and cognitive function,and achieve the purpose of helping patients recover part or all of their motor and sensory abilities.In order to improve the problems of single training mode and boring training process in the current rehabilitation equipment,and avoid the use of too limited MIBCI interactive paradigm interface,so as to improve the rehabilitation effect and progress of patients.Based on the theory and method of design,combined with cognitive neuroscience,this thesis starts with the interactive paradigm interface of MIBCI system,and uses physiological experiments such as EEG and eye movement and subjective evaluation to study the MI-BCI interactive interface and rehabilitation equipment related theories.The design status of rehabilitation equipment is analyzed by using product design methods such as market research,competitive product analysis and user research.Secondly,the interactive paradigm interface of the existing MI-BCI system is sorted out and summarized by literature analysis.On this basis,according to the previous design principles of MI-BCI sports rehabilitation equipment,the interface of MI-BCI sports rehabilitation equipment system is analyzed and designed.Through objective physiological data such as EEG and eye movement and subjective evaluation,it is proved that the designed equipment system interface can effectively improve user satisfaction and system efficiency.Finally,under the guidance of the design strategy,a design scheme based on MI-BCI sports rehabilitation equipment was produced.The overall research results and ideas have certain reference significance for the system interactive interface design and modeling design practice based on MI-BCI sports rehabilitation equipment.
