Systems and methods for programming a neuromodulation system
First Claim
1. A method of modifying a neuromodulation parameter set, comprising:
- determining a first index for a first plurality of neuromodulation parameters, wherein the first plurality of neuromodulation parameters are part of a first neurostimulation program;
determining a first normalized value for the first index as a percentage of a first patient perception threshold index;
identifying a second patient perception threshold index;
determining a second index from the identified second patient perception threshold index and the determined first normalized value;
determining a second plurality of neuromodulation parameters from the determined second index; and
modifying at least one of the first plurality of neuromodulation parameters to result in the second plurality of neuromodulation parameters and a second neurostimulation program.

Abstract
A method of operating an implantable neuromodulator includes calculating an index for each of a plurality of modulation parameter sets, wherein each modulation parameter set includes a respective plurality of modulation parameters from which the respective index is calculated, serially conveying electrical modulation energy to a patient in accordance with each of the plurality of modulation parameter sets, causing the patient to perceive paresthesia in response to the conveyance of the electrical modulation energy to the tissue in accordance with one of the plurality of modulation parameter sets, identifying the calculated index for that one modulation parameter set as a perception threshold index based on the perceived paresthesia, and storing the identified perception threshold index. The method may also include determining a new modulation parameter set based on the identified perception threshold index, and conveying electrical modulation energy to the tissue in accordance with the new modulation parameter set.
