Interventions
BCI intervention group:The intelligent brain-computer interface system based on motion image EEG is mainly composed of three parts: motion image EEG acquisition system, hand function air pump and supp
Assist the patient to take a comfortable seat, about 50 cm away from the prompt screen
Wear EEG cap and hand function air pump
Patients complete MI tasks after visual and listening to text prompts, which are judged by the EEG system. If the EEG intensity changes exceed the set threshold value, the computer will give a rewardi
Control group:In addition to receiving the same amount of routine rehabilitation training for cerebral infarction as the BCI intervention group, the patients also received the same length of treatment
