Peripheral Nerve Stimulators (PNS) are devices that are implanted for peripheral neuropathic pain. PNS therapy requires implantation of a metal lead that sits near the target peripheral nerve. The lead is implanted in a minimally invasive procedure under ultrasound guidance. The lead is stimulated externally by a battery using conductive radiofrequency signals. When the lead is stimulated, it in turns stimulates the peripheral nerve resulting in pain relief.
Studies have demonstrated that use of peripheral nerve stimulation has resulted in significant pain relief (~75% reduction in pain scores). Patients with PNS devices have also found significant improvements in function, work abilities, sleep, quality of life, and reduction in medication use. Patients with a pain from a specific peripheral nerve are eligible but certain exclusions apply.
