[Abstract] Objective: To investigate the change of brain motor functional connectivity in ischemic stroke patients after rehabilitative treatment with resting-state functional MRI(fMRI).Materials and Methods: Resting-state fMRI was employed on two sub-acute ischemic stroke patients before and after the rehabilitative treatment with functional electric stimulation (FES), and the difference of brain motor functional connectivity was analyzed.Results: After rehabilitative treatment, motor function of upper extremity was ameliorated, and functional connectivity of bilateral motor cortex was decreased. There was the correlation between behavioral improvement and connectivity decrease.Conclusion: The dependence of affected cerebral hemisphere on unaffected cerebral hemisphere was decreased after motor functional improvement of upper extremity.
