Overview
Understanding spinal cord stimulation
Thin leads are placed in the epidural space and connected to a pulse generator. The system sends low-level electrical signals that alter pain signaling. Modern systems may use settings that do or do not create a tingling sensation.
This therapy is generally considered after less invasive options have not provided enough improvement. Selection includes review of the pain diagnosis, prior treatment, health risks, goals, and ability to manage and follow up with the device.
Useful context
When this may be discussed
- Selected persistent neuropathic pain patterns
- Some pain that continues after spine surgery
- Other chronic pain conditions after appropriate evaluation and earlier treatment
At the clinic
What the process may involve
- 01
A detailed assessment, review of prior treatment, imaging, and device goals
- 02
A temporary trial to judge whether stimulation provides meaningful benefit
- 03
Permanent implantation only if the trial and overall evaluation support it
- 04
Programming, wound care, device education, and ongoing follow-up
Benefits, limits, and risks
Questions to discuss before treatment
- Implantation involves surgery and does not guarantee a particular level or duration of relief.
- Risks include infection, bleeding, lead movement, device problems, spinal-fluid leak, and rare nerve injury.
- MRI planning, security screening, driving, charging, and future procedures require device-specific guidance.

Questions and answers
Spinal cord stimulation FAQs
How does spinal cord stimulation work?
Spinal cord stimulation uses a small implanted device that delivers mild electrical pulses to the spinal cord, interrupting pain signals before they reach the brain. The device includes leads placed in the epidural space and a battery implanted under the skin. A trial period precedes a decision about permanent implantation.
Is spinal cord stimulation reversible?
Spinal cord stimulation involves a trial and, when appropriate, a longer-term system. The clinician explains the process, expected goals, limitations, and risks before treatment.
