Description

Hand rehabilitation training system Technical Field The application relates to the technical field of rehabilitation training instruments, in particular to a hand rehabilitation training system. Background The active rehabilitation technology based on the brain-computer interface has the core principle that the movement intention is analyzed from brain wave data of a patient, and the patient is assisted to execute active training through a movement device, so that a closed-loop nerve feedback mechanism is realized, and the cerebral nerve function remodeling of the patient is promoted. The technology mainly relates to three hardware modules, which respectively correspond to the functions of signal acquisition, intention decoding and motion feedback. In a traditional brain-computer interface system, a user generally adopts a multichannel electroencephalograph to acquire electroencephalogram data, sends the data to a computer for online analysis, and finally realizes motion feedback by means of an exoskeleton system. The brain computer acquisition device in the existing brain wave-based hand rehabilitation training instrument is similar to a helmet, is provided with a plurality of brain electrodes to acquire brain waves of a patient, and then the exoskeleton manipulator can execute corresponding actions according to the analyzed signals, but the existing brain computer acquisition device is basically of a fixed structure, is difficult to adapt to patients with different head circumferences, and leads to the difficulty in tightly fitting part of brain electrodes to the head of the patient, so that the full acquisition of the brain waves is influenced, and the exoskeleton manipulator cannot accurately execute the corresponding actions. Disclosure of utility model The application mainly aims to provide a hand rehabilitation training system, which aims to solve the technical problems that the existing hand rehabilitation training instrument based on brain waves is difficult to adapt to patients with different head circumferences, and insufficient brain wave acquisition is easy to cause.
