1. A method for assisting the planning or performing of spinal cord neuromodulation in a patient, comprising: having a functional image of the patient's spinal anatomy, wherein the functional image of the spinal anatomy includes an electrode and information defining functional regions of the spinal anatomy according to one or more neurologic functions; determining the position of the electrode relative to the functional regions; selecting a target functional region of the spinal anatomy; having an electric field model of an electrode positioned adjacent the patient's spinal cord; determining one or more electrode neuromodulation settings that produces a volume of activation that at least partially encompasses the targeted functional region of the spinal anatomy; and displaying the volume of activation on a display screen.
