13. A method of operating a neurostimulation device, comprising:
-
outputting a pulsed electrical waveform from the neurostimulation device between a plurality of electrodes in accordance with a specified pulse amplitude and a specified pulse width; maintaining the pulsed electrical waveform between a first strength-duration curve for relatively large fibers of neural tissue and a second strength-duration curve for relatively small fibers of the neural tissue, whereby the relatively large fibers are stimulated and the relatively small fibers are not stimulated; allowing the relatively large fibers of the neural tissue to neurological accommodate when the pulsed electrical waveform is between the first and second strength-duration curves; and increasing one or both of the specified amplitude and the specified pulse width, such that the pulsed electrical waveform is on or above the second strength-duration curve, whereby the relatively small fibers are stimulated. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
