Objective To assess any differences in brain activation during active, passive and imaginary movement of the hands using blood oxygen level-dependent functional magnetic resonance imaging (fMRI), to provide references for cortical reorganization patients with injuries.

Methods Twenty healthy, right-handed, adult volunteers were studied. fMRI was performed fist clutching. Whole analysis group applied get voxels, volume activation, peak t-score its coordinates.

Results Active both produced significant contralateral sensorimotor cortex, supplementary motor area ipsilateral cerebellum. The cortex most frequently strongly activated area. Imaginary bilateral area.

Conclusions Active induce similar patterns. This indicates that might replace active when observing brain's rehabilitation hemiplegia.
