Systems and methods for programming a neuromodulation system

摘要

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.

1. A method of operating an implantable neuromodulator coupled to an electrode array implanted adjacent tissue of a patient having a medical condition, comprising:
calculating an index for each of a plurality of modulation parameter sets to provide each of the plurality of modulation parameter sets with a respective calculated index, wherein each modulation parameter set includes a respective plurality of modulation parameters, and wherein the respective calculated index for each of the plurality of modulation parameter sets is calculated as a function of the respective plurality of modulation parameters; serially conveying electrical modulation energy to the tissue 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 respective calculated index for the one of the plurality of modulation parameter sets as a perception threshold index based on the perceived paresthesia; storing the identified perception threshold index; determining a new modulation parameter set for a sub-threshold therapy based on the identified perception threshold index; and delivering the sub-threshold therapy, including conveying sub-threshold electrical modulation energy to the tissue in accordance with the new modulation parameter set.
