The study aimed at investigating the primary motor cortex (PM) plasticity of five both upper extremities amputees with different foot movement skill. fMRI data showed that tope tapping of the amputees possessing more excellent foot movement skill activated the bilateral hand area, and top movement of the amputees possessing less skill activated the contralateral hand area. The amputees without foot movement skill only activate the foot area while toe tapping. We consider that plasticity of PM is responsible for obtaining foot movement skill and reorganization of PM in the amputee is related with higher and more complex brain functions.
