- Registration Number
- NCT05427422
- Lead Sponsor
- Health Science Center of Xi'an Jiaotong University
- Brief Summary
This study is aimed to investigate the post-stroke motor recovery of patients with ischemic stroke based on their neural features extracted from EEG-fMRI data.
- Detailed Description
A group of patients with ischemic stroke and age/gender matched healthy controls would be enrolled in this study. Their features of neural activities based on EEG-fMRI fusion scan would be extracted to investigate the mechanisms of motor recovery after stroke. Particularly, the correlations of their features of neural networks or local activities to their motor function (defined as their Fugl-Meyer scores) at enrollment and their recovery time courses consisted of Fugl-Meyer scores in follow-up time points.

Group Intervention Description High Recovery MRI recording Effective recovery rate defined as difference between Fugl-meyer scores in the 6 weeks after stroke onset (eF) and in the enrollment (sF) normalized by (total score-sf) would be used to indicate the recovery Level of a patients, i.e., (eF-sF)/ (total score-sf). A previously reported recovery rate, i.e., proportional recovery((eF-sF)/(total score-sf)=0.7) was chosen as a standard of a high recovery. Patients with effective recovery rate higher than 0.7 at the T1 time point (6 weeks after stroke onset) would be assigned to group with high recovery rate High Recovery EEG recording Effective recovery rate defined as difference between Fugl-meyer scores in the 6 weeks after stroke onset (eF) and in the enrollment (sF) normalized by (total score-sf) would be used to indicate the recovery Level of a patients, i.e., (eF-sF)/ (total score-sf). A previously reported recovery rate, i.e., proportional recovery((eF-sF)/(total score-sf)=0.7) was chosen as a standard of a high recovery. Patients with effective recovery rate higher than 0.7 at the T1 time point (6 weeks after stroke onset) would be assigned to group with high recovery rate Low Recovery MRI recording The Low Recovery group indicates that patients with effective recovery rate lower than 0.7 Low Recovery EEG recording The Low Recovery group indicates that patients with effective recovery rate lower than 0.7 Healthy Control MRI recording Age/sex matched healthy subjects enrolled to compare with group of patients. Healthy Control EEG recording Age/sex matched healthy subjects enrolled to compare with group of patients.
