Problems solved by technology

For the classification algorithm of motor imagery, it is difficult to obtain the EEG data of patients, and the amount of effective data is small, so it is difficult to train a high-quality model
At the same time, the individual differences and inter-individual differences of EEG signals are relatively large, that is, the differences in the characteristics of EEG signals of different individuals and the differences of EEG signals of the same individual with the advancement of training are very large, resulting in poor classification performance. , thus affecting the accuracy of model training

Abstract

A brain-controlled hybrid intelligent rehabilitation method based on a novel deep learning model comprises the steps of acquiring a motor imagery electroencephalogram signal of a testee through a brain-computer interface composed of an electrode cap and portable electroencephalogram signal collection equipment, and the motor intention of the testee is decoded through a decoding model; controllingrehabilitation equipment to assist the testee in performing limb movement according to the movement intention of the testee; wherein the decoding model is obtained by training a deep learning model through a training data set, and the decoding model is continuously updated along with advancing of rehabilitation training of the testee so as to adapt to electroencephalogram characteristic changes ofthe testee; wherein the training data set comes from a motor imagery database, and the motor imagery database is used for storing collected electroencephalogram signal samples of a testee and markingtime marks and action labels. According to the method, the decoding model can be updated in real time to adapt to electroencephalogram characteristic changes in the training process of a patient, sothat the classification effect of electroencephalogram signals is effectively improved, and a more efficient rehabilitation training effect is achieved.
