Nerve stimulation is a reversible technique that is used successfully for the treatment of traumatic neuropathic pain, complex regional pain syndrome, and craniofacial neuropathic pain. Nerve field stimulation targets painful regions rather than a single nerve and has expanded indications, including axial low back pain. ⋯ Ongoing research is necessary to provide high-level evidence for the use of nerve stimulation. Most electrodes are primarily designed for spinal cord stimulation, hence the need to develop nerve electrodes dedicated for nerve stimulation.

Although the first publications on clinical use of peripheral nerve stimulation for the treatment of chronic pain came out in the mid-1960s, it took 10 years before this approach was used to stimulate the occipital nerves. The future for occipital nerve stimulation is likely to bring new indications, devices, stimulation paradigms, and a decrease in invasiveness. As experience increases, one may expect that occipital nerve stimulation will eventually gain regulatory approval for more indications, most likely for occipital neuralgia, migraines and cluster headaches. This process may require additional studies, at least for approval from the US Food and Drug Administration.

ReviewEvolving Techniques and Indications in Peripheral Nerve Stimulation for Pain.
Peripheral nerve stimulation is the direct electrical stimulation of named nerves outside the central neuraxis to alleviate pain in the distribution of the targeted peripheral nerve. These treatments have shown efficacy in treating a variety of neuropathic, musculoskeletal, and visceral refractory pain pathologies; although not first line, these therapies are an important part of the treatment repertoire for chronic pain. With careful patient selection and judicious choice of stimulation technique, excellent results can be achieved for a variety of pain etiologies and distributions. This article reviews current and past practices of peripheral nerve stimulation and upcoming advancements in the field.
