Lumbar Spinal Cord Trial Stimulation wire electrode neuro-surgery animations. Special pain nerves carry pain messages from the body through the spinal cord, to the brain. When the messages reach the brain, we become aware of the pain. If the adjacent non-pain nerves in the spinal cord are activated, it can decrease the transmission of the pain nerve’s pain messages to the brain and hence decrease our awareness of the pain.

Spinal cord stimulation is used to decrease the sensation of pain from a particular area of the body by activating the adjacent non-pain nerves. The first spinal cord stimulation system was implanted in 1967. A strip of electrodes on a lead is placed in the epidural space next to the spinal cord in the spinal canal.
