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.
