Abstract
A case of alien sign of the right foot was reported. The patient was a 34-year-old right-handed male who suffered from left anterior cerebral artery territory infarction. Ischemic cerebral lesions confirmed by MRI were located in the left supplementary motor cortex, the central portion of the left cingulate cortex and the middle portion of the corpus callosum. Right hemiparesis, grasp reflex, instinctive grasp reaction, alien hand sign and compulsive manipulation of tools with the right hand were observed. We further observed the following characteristics in addition to hand behavior : (1) The patient manifested uncooperative behavior of the right foot against his will ; (2) The left hand and left foot inhibited behavior of the right foot We considered this phenomenon to be “alien sign” of the foot as well as the hand.
