Abstract
A method of managing chronic pain and/or symptoms of motor dysfunction produced by a variety of disorders or conditions. The method includes techniques for positioning one or more stimulation leads so as to enable delivery of electrical energy to epidural spinal nervous tissue, spinal ganglia, nerve plexi, or peripheral nerves using superior-to-inferior and/or trans-spinal advancement relative to a vertebral column and stimulating selected spinal nervous tissue.
