4. The rehabilitation analysis management system based on brain imaging stroke patient data according to claim 3, wherein the specific way of analyzing and processing the experimental data by the resting state analysis end is as follows:
removing the first 10 time point data due to the instability of the initial signal;
and (3) performing head movement correction on the data, wherein the removal standard is as follows: each axis is displaced by >1mm or rotated by >1 °;
the data is spatially standardized, different brain images are required to be spatially standardized due to the difference of the tested brain in anatomical structures, T1 images of all experimenters are standardized to a T1 template, and then an average structural image is generated on average;
smoothing the data with a 4mm full width half maximum Gaussian kernel;
and removing data with excessive head movement, adopting programmed REST software, respectively using a functional connection method, a low-frequency amplitude method and a local consistency method to obtain respective results, counting the functional connection differences between the ROIs and the whole brain, and obtaining difference parameters.
5. The rehabilitation analysis management system based on cerebral imaging stroke patient data according to claim 4, wherein the specific way for the task state analysis end to analyze three sets of training data corresponding to three sets of task blocks is as follows:
when a tested patient is subjected to MRI scanning, the tested patient can watch the actions of both hands in the video through the reflectors and receive auditory stimuli, and the three task blocks are A, B and C task blocks respectively;
the A task block is an action observation group, wherein the action observation group refers to that a patient observes actions and simultaneously hears action sounds and imitates actions, the patient looks at virtual double-hand actions through VR glasses and simultaneously hears action related sounds, and the hand is healthy to imitate actions on a screen;
the task B module is an action vocabulary processing group, wherein the action vocabulary processing group refers to that a patient looks at vocabularies and simultaneously hears corresponding verbs and imitates actions, and the patient looks at continuously presented action vocabulary text pictures through VR glasses and simultaneously hears the corresponding verbs;
the C task block is a 'vision-hearing-moving' multichannel integration group, and a patient firstly looks at virtual double-hand actions through VR glasses and simultaneously hears action-related sounds; then looking at the text picture corresponding to the action, and hearing the corresponding verb at the same time;
each chunk comprises 10 sections of video, 40s total, and each section of manual video is 4s;
when the task A is executed, analyzing the hand motions of the cerebral apoplexy personnel and hearing related motion sounds, checking the execution degree, and marking the execution degree as ZXa;
when the task B is executed, verb characters of a cerebral apoplexy person are acquired, the cerebral apoplexy person listens to sound of action words, the execution degree is checked, and the action words are marked as ZXb;
when executing the task block C, the content of the task block A and the content of the task block B are subjected to centralized execution processing, and an execution degree parameter ZXc is obtained;
and transmitting the execution degree parameters, the ratio parameters, the reduction parameters of the structural integrity of the gray matter on the damaged side after the cerebral apoplexy and the functional connection difference parameters between the ROIs and the whole brain of different cerebral apoplexy personnel into a comprehensive evaluation end.
