Peripheral nerve field stimulation is a relatively new technique and involves placement of stimulator leads into the subcutaneous tissue (just underneath the skin) to stimulate the distal nerve endings and provide a “field” of stimulation in the area of pain. Many patients find this to be highly effective and in fact for some conditions this appears to provide greater relief than traditional spinal cord stimulation (i.e. – groin pain). Peripheral nerve field stimulation is controversial because of the limited evidence associated with this therapy at this time. Peripheral nerve field stimulation also requires a trial before permanent implantation.
