Our facility has developed robot-assistive rehabilitation using robot suits, and tested them on people with gait impairment. In this study, we obtained gait performance and rsfMRI before and after rehabilitation to investigate the relationships between rsfMRI and rehabilitation. In the result, the rsfMRI findings in the supplementary motor area, premotor area, orbitofrontal cortex, and lateral prefrontal cortex were related to motor function recovery in rehabilitation. rsfMRI prior to rehabilitation may help to predict the recovery during rehabilitation.
