Abstract
A method of providing therapy to a patient having a medical condition comprises delivering electrical stimulation energy to the 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. The delivered electrical stimulation energy generates a plurality of electrical fields having different orientations that stimulate the dorsal horn neuronal elements.
