System and method for programming an implantable spinal cord stimulation system
In one embodiment, a method for facilitating programming of an implantable pulse generator (IPG) by an external programming device, the method comprises: receiving input from a user by the external programming device to calibrate electrode combinations at a plurality of locations along one or more stimulation leads implanted within the epidural space of a patient; controlling the IPG by the external programmer to apply stimulation to the patient via the electrode combinations; receiving input from a user by the external programming device that indicates values of a respective perception stimulation threshold at each location of the plurality of locations; receiving input from a user by the external programming device that indicates values of a respective bilateral stimulation threshold at each location of the plurality of locations; calculating positions by the external programming device of each of the plurality of locations using the perception stimulation thresholds and the bilateral stimulation thresholds; and displaying calculated positions of the plurality of locations relative to a physiological midline of the patient by the external programming device.
1. A method for facilitating programming of an implantable pulse generator (IPG) by an external programming device, the method comprising:
receiving input from a user by the external programming device to program electrode combinations at a plurality of locations along one or more stimulation leads implanted within the epidural space of a patient;
controlling the IPG by the external programmer to apply stimulation to the patient via the electrode combinations;
receiving input from a user by the external programming device that indicates values of a respective perception stimulation threshold at each location of the plurality of locations, wherein the perception stimulation threshold represents a minimal stimulation level that causes perception of stimulation in the patient on either side of the body of the patient;
receiving input from a user by the external programming device that indicates values of a respective bilateral stimulation threshold at each location of the plurality of locations, wherein the bilateral stimulation threshold represents a minimal stimulation level that causes the perception of stimulation on both sides of the body of the patient;
calculating positions by the external programming device of each of the plurality of locations using the perception stimulation thresholds and the bilateral stimulation thresholds; and
displaying calculated positions of the plurality of locations relative to a physiological midline of the patient's spinal cord by the external programming device.
2. The method of claim 1 wherein the one or more stimulation leads comprises two percutaneous stimulation leads implanted bilaterally in the epidural space of the patent.
3. The method of claim 2 wherein the plurality of locations comprises a distal electrode location and a proximal electrode location on each of the two percutaneous stimulation leads.
4. The method of claim 1 wherein the one or more leads comprises a paddle-style stimulation lead.
5. The method of claim 1 wherein the calculating comprises calculating a ratio between a respective bilateral stimulation threshold and a corresponding perception stimulation threshold.
6. The method of claim 1 wherein the external programming device provides one or more graphical user interface screens for entry of data to define the respective perception and bilateral threshold values.
