Abstract

A system and method for programming a neurostimulation device coupled to a plurality of electrodes implanted adjacent tissue of a patient are provided. A first electrode configuration corresponding to a first mode of programming the neurostimulation device is defined. A second programming mode of programming the neurostimulation device different from the first programming mode is selected. A second electrode configuration is defined based on the first electrode configuration in response to the selection of the second programming mode. The neurostimulation device is programmed using the second programming mode.
