A Novel Mini-invasive Approach to the Treatment of Neuropathic Pain: The PENS Study.

Background: Peripheral neuromodulation is often used as chronic neuropathic pain treatment. Percutaneous electrical nerve stimulation (PENS) is generally utilized with several probes at the same time and repeated treatments.

Objectives: Evaluate the short- and long-term efficacy of a single probe and single shot PENS approach.
