Systems and methods for selecting low-power, effective signal delivery parameters for an implanted pulse generator

摘要

Systems and methods for selecting low-power, effective signal delivery parameters for an implanted pulse generator are disclosed. A representative system includes a signal generator and a computer-readable medium that, for first and second signals, increases and decreases an amplitude of the signal over multiple steps from a baseline amplitude at which the patient has a baseline response. At individual step increases and decreases, the system receives a pain score based on the patient's response. The instructions compare the pain scores for the two signals and determine one of the signals for additional therapy to the patient, based on the pain scores and an expected energy consumption of the signals.

1. A method for configuring a spinal cord stimulation system for providing pain relief to a patient, wherein the spinal cord stimulation system includes a signal generator configured to generate an electrical therapy signal, and a signal delivery device configured to receive the electrical therapy signal from the signal generator and deliver the electrical therapy signal to the patient's spinal cord region, the method comprising:
(a) configuring the signal generator to deliver a first therapy signal with a first set of therapy signal parameters, wherein the first set of therapy signal parameters includes a first frequency in a frequency range from 10 kHz to 100 kHz, inclusive; (b) configuring the signal generator to deliver a second therapy signal with a second set of therapy signal parameters, wherein the second set of therapy signal parameters includes a second frequency in a frequency range from 1.5 kHz to 10 kHz, (c) for both the first and second signals:
(i) increasing an amplitude of the signal, over multiple steps, from a baseline amplitude at which the patient has a baseline pain score;(ii) for individual step increases, determining a pain score based on the patient's response to the increased amplitude;(iii) decreasing the amplitude over multiple steps; and(iv) for individual step decreases, determining a pain score based on the patient's response to the decreased amplitude; (d) comparing the pain scores corresponding to the first therapy signal with the pain scores corresponding to the second therapy signal; and (e) based on the pain scores and an expected energy consumption for the first and second therapy signals, selecting one of the first and second therapy signals for additional therapy to the patient.
