Spinal Cord Stimulation

Top view of vertebra and spinal cord showing spinal cord stimulator.Pain messages travel over nerve pathways to the spinal cord, inside the spine. The spinal cord carries the messages to the brain. Constant pain messages can cause long-term pain that is hard to treat. This is known as chronic pain. Spinal cord stimulation uses a medical device to send signals to the nerve pathways inside your spinal cord. These signals help block the pain.

Keeping a pain log

Your doctor may ask you to keep a pain log for a certain amount of time. In it, you may answer certain questions:

  • When do you feel pain?

  • What does it feel like?

  • How long does the pain last?

  • What makes it better or worse?

  • When the stimulation is on, is your pain relieved?

Your answers help show how well spinal cord stimulation may work for you. Your doctor will give you guidelines for your pain log. During the time you write the log, you may not be able to take pain medicine. Be sure to discuss this with your doctor.

Spinal cord stimulation may help

Spinal cord stimulation is one treatment for chronic pain. Certain criteria need to be met to be a good candidate for spinal cord stimulation. A small medical device sends signals to your spinal cord. These signals keep the chronic pain messages from being sent to your brain. Instead, you may feel tingling from the electrical signals. A trial stimulator that is worn outside the body is tried first to see if it will work. If it does, the permanent stimulator system may be used. This device can be removed at any time.

The stimulator system

The stimulator system has several parts. A power source makes the signals. This power source may be worn outside the body or implanted under the skin of the abdomen or buttocks. One or more leads (flexible, plastic-covered wires or paddle) are placed inside the body to carry the signals to the spinal cord. Your doctor can explain the system you’ll be using in more detail.
