This application relates to the field of neurorehabilitation engineering and discloses a rehabilitation system based on central-peripheral fusion decoding and trajectory closed-loop correction. The system's training subsystem collects EEG signals from the affected side, peripheral electromyography (EMG) signals from the healthy side, and peripheral kinematic signals, constructing a "fusion-type teacher signal" of peripheral EMG and peripheral kinematic signals. A deep learning model is then trained to learn the mapping from EEG signals to this fusion signal. The system's application subsystem, based on real-time EEG signals, simultaneously predicts coordinated EMG patterns and coordinated movement trajectories using the model. The coordinated EMG patterns are used to generate feedforward instructions for functional electrical stimulation to reproduce physiological coordination patterns; the coordinated movement trajectory serves as a dynamic target trajectory, compared with the actual kinematic signals from the affected side, and the trajectory error is calculated to generate feedback correction instructions for functional electrical stimulation. This application achieves natural, precise, and personalized motor assistance.
