A neurostimulator is a small, surgically implanted device about the size of a stopwatch. It delivers mild electrical signals to the epidural space near your spine through one or more leads (special medical wires). The electrical signals cause a tingling sensation in the area of your chronic pain.
Neurostimulation provides pain relief by modulating (modifying) the pain messages before they reach the brain. Think of it like rubbing your "funny bone" after you've bumped it – the rubbing masks the feeling of pain. Similarly, the tingling produced by the neurostimulation system masks the feeling in your area of pain.
You can adjust the strength and location of stimulation using a handheld programmer. For example, you can regulate different levels of stimulation at different times of the day or for various activities – such as walking, sleeping, or sitting.
A complete neurostimulation system consists of five parts:
The neurostimulation system does not make any noise. It may be felt as a small bump under your skin, but does not normally show through your clothes.
