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. The electrode delivers rapid electrical pulses that are felt like mild tingles. 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. These devices are an extremely safe, efficient, and effective way to ameliorate a variety of severe neuropathic pain conditions.
