Peripheral Nerve Stimulation Implant

Peripheral nerve stimulation (PNS) is a form of neuromodulation used for selected chronic pain conditions in which a specific peripheral nerve is thought to be generating or maintaining pain. It may be considered when pain remains troublesome despite medication, physiotherapy, injections or other appropriate treatments, particularly when a clear nerve target can be identified.

The treatment involves placing a small electrical lead close to the selected peripheral nerve, usually under image guidance. The lead is connected to a small pulse generator, which may be positioned under the skin or, depending on the system, used as part of a temporary or external arrangement. Electrical stimulation is programmed to modulate pain signals travelling along the targeted nerve.

Some patients undergo a trial period before a longer-term implant is considered, allowing the response to be assessed during normal activities. If meaningful improvement in pain and function is achieved, longer-term treatment may be discussed. PNS is not suitable for every pain condition, and Dr Danesh will assess the pain diagnosis, nerve target and expected benefits before recommending it.
