A method of stimulating patient nerve tissue includes implanting an electrical stimulation lead in a patient. The electrical stimulation lead includes multiple electrodes disposed thereon and the electrodes are implanted in an epidural space adjacent a spinal cord of the patient. The method further includes coupling the electrical stimulation lead to a control module implanting the control module in the patient and generating stimulation current in the control module and delivering the stimulation current to at least one of the electrodes on the electrical stimulation lead. That electrode is an anode and a cathode is provided on the control module. The method also includes electrically stimulating at least one patient nerve tissue using the stimulation current. The stimulated patient nerve tissue is disposed beyond the spinal cord and dorsal and ventral roots extending from the spinal cord.
