Various system embodiments comprise a lead having a distal end and a proximal end. The distal end includes a plurality of electrodes. The lead is configured to be fed into a dorsal epidural space of a human to a desired region of a spinal column and to be fed laterally to at least partially encircle a spinal cord in the desired region to place at least one stimulation electrode in position to stimulate a dorsal nerve root and at least another stimulation electrode in position to stimulate a ventral nerve root. The desired region may include cervical vertebrae, thoracic vertebrae, or lumbar vertebrae. Some embodiments stimulate the spinal cord in the T1-T5 region.
