Similar to spinal cord stimulators (SCS), patients can receive peripheral nerve stimulators (PNS), devices that interfere with chronic pain signaling from nerves located outside of the spine. PNS is used to treat chronic pain due to damaged peripheral nerves, migraines, and overactive bladder.

This method does not eliminate the source of pain but, instead, blocks the sensation so that the patient feels less of it. The device is programmed to provide each patient with settings that are best suited to their condition. Before a permanent stimulator device is placed in the body, patients are able to trial an external version.

The amount of relief provided varies from person to person and, if the trial stimulator is unsuccessful, it can easily be removed and the patient can pursue other forms of treatment.
