영문 초록

We investigated the activation of the cerebral cortex during active movement, passive movement, and functional electrical stimulation (FES), which was provided on wrist extensor muscles. A functional magnetic resonance imaging study was performed on 5 healthy volunteers. Tasks were the extension of right wrist by active movement, passive movement, and FES at the rate of .5 ㎐. The regions of interest were measured in primary motor cortex (M1), primary somatosensory cortex (SⅠ), secondary somatosensory cortex (SⅡ), and supplementary motor area (SMA). We found that the contralateral SⅠ and SⅡ were significantly activated by all of three tasks. The additional activation was shown in the areas of ipsilateral SⅠ (n=2), and contralateral (n=1) or ipsilateral (n=2) SⅡ, and bilateral SMA (n=3) by FES. Ipsilateral M1 (n=1), and contralateral (n=1) or ipsilateral SⅡ (n=1), and contralateral SMA (n=1) were activated by active movement Also, Contralateral SMA (n=3) was activated by passive movement. The number of activated pixels on SM1 by FES (12±4 pixels) was smaller than that by active movement (18±4 pixels) and nearly the same as that by passive movement (13±4 pixels). Findings reveal that active movement, passive movement, and FES had a direct effect on cerebral cortex. It suggests that above modalities may have the potential to facilitate brain plasticity, if applied with the refined-specific therapeutic intervention for brain-injured patients.
