A system comprises a bendable, pre-formed lead body operable to be implanted proximate a neural pathway of a patient. A first electrode comprising a plurality of first segments at a first longitudinal location of the lead body is configured to be positioned at a lateral epidural region proximate at least one nerve root of the patient, and a second electrode comprising a plurality of second segments at a second longitudinal location of the lead body is configured to be positioned along a midline of the patient's spinal column. The system further includes a signal generator electrically coupled to at least one of the first and second electrodes and a processor coupled to the signal generator and operable to apply a stimulation signal to at least one of the first and second electrodes.
