Abstract
An example of a system may include electrodes on at least one lead configured to be operationally positioned for use in modulating neural tissue where the neural tissue including dorsal horn tissue or nerve root tissue, a neural modulation generator, and a controller. The neural modulation generator may be configured to use at least some electrodes to generate a modulation field. The neural modulation generator maybe configured to use a programmed modulation parameter set to promote uniformity of the modulation field in the dorsal horn tissue. The controller may be configured to control the neural modulation generator to generate the modulation field in pulse trains of at least two pulses.
