Advances in the application of motor imagery based brain computer interface systems for brain function activation and neural network remodeling in patients with paralysis after stroke / 中华神经科杂志

ABSTRACT

Motor imagery (MI) and its related brain computer interface (BCI) technologies have been used for speech and movement disorders in patients with spinal cord injury, stroke, multiple sclerosis, etc. Current studies have shown that BCI can activate brain function in stroke patients with enhanced frequency, longer duration and more stable electroencephalogram signals. Imaging results showed a significant increase in functional connectivity between the two hemispheres and within the affected hemispheres. In this paper, MI-BCI for stroke patients with brain function activation and neural network remodeling were reviewed, the research progress on mechanisms of the technology was summarized, to provide reference for the application of the technology in clinical and future research.
