  • Abstract
  • Look Inside

A 60-year-old, right-handed man suffered from left hemiparesis with upper limb dominance. CT and MM revealed cerebral infarction of the entire right middle cerebral artery territory. His hemiparesis recovered excellently and residual neurological deficits 6 years later were left hand weakness (grasping power 9 kg vs. 35 kg in the right) and clumsiness. Functional MRI was performed . During right (normal) hand grasping, activation was seen in the left sensorimotor cortex and supplementary motor area.
