Therapy
Spinal Cord Stimulator
A spinal cord stimulator is an implanted device that sends mild electrical pulses to the spinal cord to reduce long-term nerve pain.
Quick answer
Spinal Cord Stimulator: what it is, why it's done and what happens
A spinal cord stimulator places thin electrodes near the spinal cord, connected to a small implanted generator. The pulses change how pain signals reach the brain, replacing pain with a tingling sensation or reducing it.
- Why it is done: It is used for certain types of chronic nerve pain that have not responded to other treatments, such as persistent pain after back surgery or some nerve pain conditions.
- What happens: A trial is usually done first with temporary leads to see if it helps.
What it is
A spinal cord stimulator places thin electrodes near the spinal cord, connected to a small implanted generator. The pulses change how pain signals reach the brain, replacing pain with a tingling sensation or reducing it.
Why it is done
It is used for certain types of chronic nerve pain that have not responded to other treatments, such as persistent pain after back surgery or some nerve pain conditions.
What happens
A trial is usually done first with temporary leads to see if it helps. If successful, the permanent electrodes and generator are implanted under general or local anaesthetic in a minor operation.
Recovery
Recovery from the implant is usually quick. The device settings are adjusted to find the most effective pattern of stimulation. Activity is limited briefly to let the leads settle.
Good to know
Risks and things to consider
Risks include lead movement, infection, and the device not giving enough pain relief. It manages pain rather than curing the cause, and the battery may eventually need replacing.

Answers
Spinal Cord Stimulator: frequently asked questions
Why is a trial done first?
A trial with temporary leads lets you and your team see whether stimulation actually reduces your pain before committing to a permanent implant, improving the chance of a worthwhile result.
Does the stimulator cure my pain?
No. It aims to reduce pain and improve function and quality of life, but it does not cure the underlying condition, and results vary between people.
