The aim of this study is to investigate whether there is consistency between active and passive movement in patients with brain tumors. Two motor tasks (active and passive hand movement) were applied to brain tumor patients. Our results demonstrate that there is no statistical difference of activation intensity between active hand movement and passive hand movement in patients with brain tumors. Our results suggest that passive movement fMRI provides a potential method for presurgical mapping in cases where patients are unable to comply with task instructions.
