ABSTRACT
Objective To observe the cerebral activation by functional MRI(F MRI) during the thumb movement in different motor fashion. Methods Four stroke patients with hemiplegia were involved in this study During the examination by F MRI, these patients were asked to move thumbs in passive, active and overcoming resistance fashion. Results (1) During the thumb at unaffected side moving in active fashion, functional activity was observed in the contralateral primary motor cortex In passive fashion, however, functional activity was observed in contralateral somatosensory cortex The overcoming resistance motor test was associated with activity in bilateral primary motor cortex and somatosensory cortex (2) The same motor tests were made in movement of the thumb at affected side , functional activity appeared not only in primary motor cortex, somatosensory cortex of affected side, but also in basal ganglia(affected area), frontal lobe, supplementary motor cortex, somatosensory cortex, and contralateral primary motor cortex. Conclusion These results have proved the neurorehabilitation theory such as neuroplasticity and so on
