METHODS AND SYSTEMS FOR AUTOMATICALLY TURNING ON AND OFF DRG STIMULATION AND ADJUSTING DRG STIMULATION PARAMETERS

摘要

Methods and systems described herein can be used to automatically turn on and off stimulation of a target dorsal root ganglion (DRG) and/or adjust stimulation parameters. At least one of an input signal (indicative of an electrical field resulting from an electrical signal propagated by adjacent distal sensory nerve fibers toward the target DRG), an output signal (indicative of an electrical field resulting from an electrical signal propagated by adjacent proximal sensory nerve fibers away from the target DRG) or a DRG signal (indicative of an electrical field produced by cell bodies of primary sensory neurons within the target DRG and resulting from an electrical signal propagated by sensory nerve fibers within the target DRG) is/are obtained and analyzed. Delivery of electrical stimulation is turned on and off and/or at least one of pulse amplitude, pulse width and/or pulse repetition rate is/are adjusted based on results of the analysis.
