Progress in the Application of Brain-computer Interface Technology in Stroke Rehabilitation

Abstract

Stroke patients are often left with different degrees of dysfunction in different aspects, which seriously affects patients' schedule and quality of life. At present, the rehabilitation of stroke patients mainly relies on passive and repetitive training of patients, and the rehabilitation effect is not ideal. brain computer interface is a cutting-edge rehabilitation technology that completely does not rely on peripheral nerves and muscles to interact with the external environment. This technology can interpret the movement intention of patients in real time, establish the connection pathway between the human brain and the machine, and conduct closed-loop feedback training. Trigger the neuroplasticity of the brain, ultimately achieve the purpose of functional rehabilitation of stroke patients, and provide patients with individualized rehabilitation training. This paper reviews the domestic and foreign research progress of brain-computer interface technology in the field of stroke rehabilitation in recent years, expounds the working process and principle of brain-computer interface technology, summarizes its application status in the aspects of stroke limb dysfunction, cognitive impairment, speech impairment and psychological rehabilitation, and finally analyzes its challenges and development trends, with a view to promoting the rapid development of brain-computer interface technology. It provides a new idea for the rehabilitation of stroke patients.
