Peripheral Nerve Stimulator
What is a peripheral nerve stimulator? How does it help?
Peripheral nerve stimulator with implanted battery is a device to stimulate nerves. Peripheral nerve stimulation, frequently referred to as PNS, is a commonly used approach to treat chronic pain. It involves surgery that places a small electrical device (a wire-like electrode) next to one of the peripheral nerves. (These are the nerves that are located beyond the brain or spinal cord). The electrode delivers rapid electrical pulses that are felt like mild tingles (so-called paresthesias). During the testing period (trial), the electrode is connected to an external device, and if the trial is successful, a small generator gets implanted into the patient’s body. Similar to heart pacemakers, electricity is delivered from the generator to the nerve or nerves using one or several electrodes. The patient is able to control stimulation by turning the device on and off and adjusting stimulation parameters as needed.
Who would benefit from peripheral nerve stimulation?
Peripheral nerve stimulation can be used in patients with nerve injuries when other modalities of treatments fail. It is often used to reduce pain in conditions like complex regional pain syndromes (CRPS), migraine headaches, occipital neuralgia and post-surgical nerve entrapment pain.
How long does the peripheral nerve stimulation operation take?
The trial procedure, performed on an outpatient basis at Atlas Pain Care, Coimbatore, takes approximately 30 to 45 minutes and is followed by a short period of observed recovery. The procedure to implant the long-term device is performed in an outpatient surgical setting and, generally, takes about two hours.
Does it need repeating?
The peripheral nerve stimulator implant is usually permanent but can be easily reversed. Batteries will need to be replaced every few years, but this is a simple procedure.
What are the Expected Results?
Peripheral nerve stimulation (PNS) has a high success rate for reducing pain. The benefit from this procedure will occur almost immediately; however, you may experience some post-procedure soreness for a day or two.
