Technical Field
[0001] The present invention relates to the field of medical rehabilitation technology, and in particular to a movement disorder rehabilitation training method and system based on electroencephalogram signal recognition. Background Art
[0002] Limb movement disorder is a symptom of limited or uncontrollable body muscle movement due to neurological diseases or injuries. It affects the daily life of patients and brings a lot of trouble to their families. In traditional limb rehabilitation, patients passively accept mechanical training and lack active brain participation. The effect on motor nerve repair is limited and long-term training is required to achieve the ideal effect. With the continuous development of modern science and technology, brain wave monitoring and analysis technology has been widely used in rehabilitation training. Brain waves are a kind of bioelectric signal generated by neurons in the cerebral cortex and can reflect the functional state of the brain. By monitoring and analyzing brain waves, a scientific basis can be provided for rehabilitation training to help patients better restore their functions. However, in the existing technology, there are problems of low recognition speed and accuracy in the process of recognizing brain wave signals, which leads to a decrease in the recognition accuracy of brain wave signals. At the same time, it is impossible to carry out targeted training on short board training movements according to the completion of training movements. In addition, in the traditional muscle strength analysis process, there is a lack of monitoring of the user's force decision, and the user's force decision cannot be adjusted in time, resulting in a prolonged user rehabilitation training cycle. In view of the above technical defects, a solution is now proposed. Summary of the invention
[0003] The purpose of the present invention is to provide a movement disorder rehabilitation training method and system based on EEG signal recognition to solve the technical defects mentioned above. The present invention initially analyzes from the perspective of EEG signal recognition to improve the accuracy of EEG signal recognition, and performs EEG and movement dual evaluation analysis through virtual training to intuitively understand whether each training movement of the user is qualified. At the same time, it analyzes from the two perspectives of overall training completion and single movement completion to reasonably adjust the training intensity, and at the same time, carries out targeted movement disorder rehabilitation training plans for the user's shortcomings, which helps to assist the next round of rehabilitation training tasks based on this. It analyzes from the perspective of the user's muscle strength deviation. On the one hand, it dynamically adjusts the functional electrical stimulation according to the information feedback to improve the rehabilitation training effect. On the other hand, it reminds the user to adjust the force decision based on the feedback information, which helps to shorten the user's rehabilitation training cycle.

This rehabilitation training based on motor imagery can be used for most patients with nerve damage. Modern medical rehabilitation theory proves that this type of functional recovery training can promote the repair of the nervous system of paralyzed patients, and active participation of patients will achieve better rehabilitation effects than passive training.
[0016] Embodiment 2: When an available signal is generated, the rehabilitation division unit is used to perform rehabilitation action division management and analysis on the collected classified action labels, so as to carry out targeted movement disorder rehabilitation training plans based on the user's shortcomings, and then help assist the next round of rehabilitation training tasks based on this.

On the other hand, the user is reminded to adjust the force decision based on the feedback information, which helps to shorten the user's rehabilitation training cycle.
