Techniques for confirming a volume of effect of sub-perception threshold stimulation therapy
First Claim
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.

Abstract
A system may include a therapy delivery module configured to deliver electrical stimulation therapy to a tissue of a patient in accordance with a first stimulation therapy program. The first stimulation therapy program may define a first stimulation intensity below a perception threshold stimulation intensity of the patient. The therapy delivery module also may be configured to deliver electrical stimulation therapy to the tissue of the patient in accordance with a second stimulation therapy program. The second stimulation therapy program may define a second stimulation intensity at or above the perception threshold stimulation intensity. The system also may include a processor configured to determine stimulation parameter values for the first stimulation therapy program that result in a first volume of effect and determine stimulation parameter values for the second stimulation therapy program that result in a second volume of effect substantially the same as the first volume of effect.
