A method of stimulating a dorsal root ganglion includes providing an electrical stimulation lead having a distal end, a proximal end, a longitudinal length, a circumference, a plurality of electrodes disposed along the distal end of the lead, a plurality of terminals disposed along the proximal end of the lead, and a plurality of conductors. Each conductor electrically couples at least one of the electrodes to at least one of the terminals. The plurality of electrodes includes a plurality of segmented electrodes and each of the segmented electrodes extends around no more than 75% of the circumference of the lead. The method further includes implanting the electrical stimulation lead adjacent to the dorsal root ganglion and applying electrical stimulation to the dorsal root ganglion using at least one of the plurality of segmented electrodes of the electrical stimulation lead. |
