Abstract:
1. A system comprising: a therapy delivery module configured to: deliver, via one or more electrodes of a plurality of implantable electrodes, electrical stimulation therapy to a tissue of a patient in accordance with a first stimulation therapy program, wherein the first stimulation therapy program defines a first stimulation intensity below a perception threshold stimulation intensity of the patient; and deliver, via one or more electrodes of the plurality of implantable electrodes, stimulation therapy to the tissue of the patient in accordance with a second stimulation therapy program, wherein the second stimulation therapy program defines a second stimulation intensity at or above the perception threshold stimulation intensity; and a processor configured to: determine stimulation parameter values for the second stimulation therapy program that result in a second volume of effect within the patient; and determine stimulation parameter values for the first stimulation therapy program that result in a first volume of effect within the patient that is substantially the same as the second volume of effect, wherein the first volume of effect represents a first volume of tissue in which a therapeutic effect is produced, and wherein the second volume of effect represents a second volume of tissue in which stimulation therapy is perceivable by the patient.
