System and method for avoiding, reversing, and managing neurological accommodation to electrical stimulation
First Claim
1. A method of programming a neurostimulation device, comprising:
- varying an electrode combination under user control;
automatically varying an electrical pulse parameter as the electrode combination is varied under user control;
generating a plurality of stimulation parameter sets from the varied electrode combination and varied electrical pulse parameter;
outputting a pulsed electrical waveform from the neurostimulation device between a plurality of electrodes in accordance with the plurality of stimulation parameter sets, such that neural tissue is stimulated without undergoing neurological accommodation that would otherwise occur if the electrical pulse parameter were not varied; and
programming the neurostimulation device with a new set of stimulation parameters based on a result of the neural tissue stimulation.

Abstract
A method of operating a neurostimulation device comprises outputting a pulsed electrical waveform from the neurostimulation device between a plurality of electrodes while at least one of the electrodes has a first polarity, thereby stimulating neural tissue adjacent the electrode(s), allowing the neural tissue to undergo neurological accommodation in response to the electrical energy output between the electrodes, switching the electrode(s) from the first polarity to a second polarity, outputting the pulsed electrical waveform from the neurostimulation device between the electrodes while the electrode(s) has the second polarity, thereby hyperpolarizing the neural tissue to reverse the neurological accommodation, switching the electrode(s) from the second polarity to the first polarity, and outputting the pulsed electrical waveform from the neurostimulation device between the electrodes while the electrode(s) has the first polarity, thereby stimulating the previously hyperpolarized neural tissue.
