Damage to the spinal cord is known to be associated with a posterior shift of the motor cortical upper limb representation, i.e. towards the somatosensory cortex. Due to missing pre-traumatic data, knowledge resulted from comparing findings between patients and healthy subjects. Here, we present a case of transient spinal cord injury resulting in a left-sided hemiparesis for 4 weeks. By chance, this patient had a pre-lesional navigated transcranial magnetic stimulation (nTMS) motor mapping 2 years before. Hence, nTMS mapping was repeated during the acute (after 1 day), sub-acute (after 10 days) and chronic (after 2 years) phase to trace the cortical reorganization following this incident.
