Abstract

The invention provides a rehabilitation training system and method based on a motor imagery-brain-computer interface and virtual reality. An electroencephalogram signal of a subject in a rehabilitation process is collected in real time through an electroencephalogram signal collection device, and the electroencephalogram signal is preprocessed; feature extraction is performed on the preprocessed electroencephalogram signal, and a motor imagery intention recognition model is established based on extracted features; training exercise scenes in a first-person visual angle and a third-person visual angle are developed, and the training exercise scenes are rendered through a VR helmet; the subject selects two different visual angles for training in the VR environment, the subject performs motor imagery according to prompts, and when the subject imagery is recognized, corresponding limbs in a scene complete corresponding actions; rehabilitation training is scored according to quantitative indexes of the brain region activation degree related to the motor imagery of the subject obtained by performing brain network analysis on the electroencephalogram signals of the subject, and a rehabilitation report is generated. The rehabilitation training system can achieve a good rehabilitation training effect.

Description

technical field [0001] The invention relates to the technical field of rehabilitation training, in particular to a rehabilitation training system and method based on motor imagery-brain-computer interface and virtual reality. Background technique [0002] Stroke is a disease of neuromuscular pathway damage caused by blocked blood supply to the brain. Brain tissue damage leads to rupture of brain nerve pathways that control functions such as movement and language, resulting in hemiplegia and even disability. According to the World Health Organization report: stroke has become the main cause of disability and high mortality in my country. In 2017, the number of deaths due to stroke in my country reached 1.96 million, and the number of stroke subjects in my country has maintained a sharp upward trend in recent years. Stroke subjects are unable to take care of themselves due to motor dysfunction, which seriously affects the physical and mental health of the subjects. How to re...
