Abstract: Methods and systems for selecting electrical stimulation parameters for an electrical stimulation device implanted in a patient can use an iterative process for identifying electrodes for stimulation, as well as suitable stimulation parameters. The process begins with an initial set of electrode combinations to identify regions of the nerve or other tissue for stimulation. This leads to selection of other electrode combinations to test, followed by the selection of multiple electrode groups (which can include three or more electrodes) for stimulation.
