Purpose

Diabetic peripheral neuropathy causes a decrease in brain afferantiation . Neuronal injury or extremity amputation causes a decrease in afferantiation or lost afferantiation as well. In the related area of the cerebral cortex, cerebral sensorial neurons make synaptic connections with the nearby motor neurons.1, 2, 3, 4 We also know that cortical neuron pool of extremity muscles that are lost due to amputation are added to the cortical motor neuron pool of the amputation stump muscles. For this reason functional cortical activation area increases.1, 2, 3, 4

The aim of this study is to detect the brain reorganization by sensory motor changes in central nervous system with functional magnetic resonance imaging (fMRI) in diabetic patients who had lower limb amputations due to peripheral neuropathy.
