Limb movement rehabilitation method and device based on brain-computer interface, storage medium and equipment

Abstract

The invention relates to a limb movement rehabilitation method and device based on a brain-computer interface, a storage medium and equipment. The invention aims to provide the limb movement rehabilitation method and device based on the brain-computer interface, the storage medium and equipment, so as to improve the recognition accuracy of the movement intention of a user and improve the rehabilitation training result. According to the technical scheme, the limb movement rehabilitation method based on the brain-computer interface is characterized by comprising the steps: acquiring the electroencephalogram state of a user; judging whether the user prepares to enter a state machine according to the electroencephalogram state of the user; acquiring an electro-oculogram and / or electromyogram signal sent by a user according to requirements, and entering a state machine after receiving the electro-oculogram and / or electromyogram signal; detecting the electroencephalogram state of the user after entering the state machine; when it is detected that the electroencephalogram state of the user contains the motion intention, sending an action execution control signal to the limb auxiliary module. The method is suitable for the field of brain rehabilitation training.

Description

technical field [0001] The invention relates to a limb movement rehabilitation method, device, storage medium and equipment based on a brain-computer interface, which is applicable to the field of brain rehabilitation training. Background technique [0002] With the intensification of the aging society, there are more and more stroke patients in our country. According to statistics, there are approximately 2.7 million new cases of stroke each year, and the incidence rate is increasing at a rate of 13% per year. In my country, the disability rate due to stroke is as high as 75%, while it is only 30% in Western countries. The main reason for the high disability rate in my country is the lack of timely and effective rehabilitation treatment. Coupled with physical impairments caused by brain injuries, cranial nerve diseases, and sports injuries, there is currently a huge demand for rehabilitation equipment in my country. However, there are still very few professional rehabilit...

AI Technical Summary

Problems solved by technology

[0004] However, at present, the rehabilitation training system based on brain-computer interface has not been widely used in clinical practice.

On the one hand, because stroke patients have different degrees of brain nerve damage and weak perception ability, it is difficult to maintain the motor intention for a long time

On the other hand, due to the limitations of the current brain-computer interface technology, there are still deficiencies in motion recognition.

Therefore, the current limb movement rehabilitation training system based on the brain-computer interface cannot fully activate the brain's motor circuit, and the sense of substitution is poor, which easily makes patients lose confidence in rehabilitation
