1. A method of programming a neurostimulation device, comprising: varying a first stimulation parameter under user control; automatically varying a second stimulation parameter as the first stimulation parameter is varied under user control; generating a plurality of stimulation parameter sets from the varied first and second stimulation parameters; 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 second stimulation 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.
