A management method for cortical plasticity in movement disorders based on transcranial electrical stimulation brain-muscle coupling

Abstract

The present invention proposes a method for managing plasticity of the movement disorder cortex based on transcranial electrical stimulation brain-muscle coupling. The present invention firstly analyzes the multi-lead EEG signals of functional brain regions, uses the brain functional network modeling method to calculate the brain functional network indicators of connectivity rate and small-world characteristics, compares the brain functional network characteristics before and after tDCS stimulation, and reveals motor activities The regularity of functional connectivity and neural remodeling in the prefunctional area, functional area, and functional perception area of ​​the stimulated hemisphere during the period. Then, the multi-level neuromuscular coupling analysis method based on the causal measure of the dynamic regression model was used to extract the characteristic indicators of brain-brain, brain-muscle and muscle-muscle coupling, and describe the rehabilitation effect of upper limb motor function from different aspects. Finally, the correlation between the characteristics of brain electromyography coupling and the influence of tDCS on neural plasticity was studied to provide a basis for further improvement of tDCS stimulation methods and parameters, and to achieve effective guidance and management of motor function cortical neural remodeling.

Description

technical field [0001] The invention belongs to the field of pattern recognition, and relates to a method for managing plasticity of motor dysfunction cortex based on external stimulus intervention and exercise rehabilitation evaluation based on the use of motor imagery in active rehabilitation robots, and in particular to a method based on transcranial direct current stimulation A method for the management of cortical plasticity in motor dysfunction by coupling analysis with brain electromyography. Background technique [0002] Stroke is one of the common cerebrovascular diseases in the world. After the onset, patients often have motor dysfunction, and the recovery of motor function is slow, difficult, and poor prognosis, which has become the focus and difficulty in rehabilitation treatment. In recent years, the rapid development of brain science, neurophysiology, brain function network theory, brain-computer interface and other interdisciplinary research results have broug...

Problems solved by technology

[0004] At present, most rehabilitation methods based on tDCS use fixed stimulation methods and parameters, and there is no flexible change mechanism based on the evaluation of rehabilitation effects, which restricts the remodeling effect of the central nervous system of motor function.
