Spinal Cord Stimulation
In this procedure, one or two wires (leads) are placed into the epidural space to provide electrical stimulation of the spinal cord, acting to interfere with the transmission of pain. This technique is very effective in arm and leg pain caused by nerve injuries and can also be useful in some types of low back pain. It has also been used to treat pain from vascular insufficiency and chest pain. The stimulation can be adjusted by the patient, thereby adding an element of personal control over the treatment of pain.
