PROGRAMMING INTERFACE FOR SPINAL CORD NEUROMODULATION
First Claim
1. A method for selecting stimulation settings, comprising:
- individually activating a plurality of contacts of a leadwire implanted adjacent to a patient'"'"'s spinal cord;
comparing, by a computer processor, a parasthesia area respectively produced by each of the activated contacts to a target area of the patient'"'"'s body;
based on the comparison, selecting, by the processor, a set of contacts and associated settings that provide the parasthesia areas that best match the target area; and
determining and outputting, by the processor, a combined set of settings that includes activations of the selected contacts, wherein an activation of at least one of the selected contacts is adjusted relative to the activation of the at least one contact in the individually activating step.

Abstract
A tool for assisting in the planning or performing of electrical neuromodulation of a patient'"'"'s spinal cord. The tool may have various functions and capabilities, including calculating a volume of activation, registering an electrode(s) shown in a radiologic image, constructing functional images of the patient'"'"'s spinal anatomy, targeting of neuromodulation, finding a functional midline between multiple electrodes, determining the three-dimensional position of multiple electrodes, and/or accommodating for electrode migration. In certain embodiments, the tool can be embodied as computer software or a computer system.
