Claim:
1. A method, comprising: providing therapy using implanted electrodes to a patient having a medical condition, wherein the providing therapy to the patient includes delivering electrical stimulation energy as a pulsed electrical waveform to a spinal cord of the patient in accordance with a stimulation program that preferentially stimulates dorsal horn neuronal elements over dorsal column neuronal elements in the spinal cord, wherein delivering electrical stimulation energy includes generating a plurality of electrical fields having different orientations at different times to stimulate the dorsal horn neuronal elements, and wherein generating the plurality of electrical fields having different orientations at different times includes generating a first electrical field having a first orientation during at least a first pulse in the pulsed electrical waveform, generating a second electrical field having a second orientation during at least a second pulse in the pulsed electrical waveform, and generating a third electrical field having a third orientation during at least a third pulse in the pulsed electrical waveform, the first, second and third orientations being different from each other.
