Auricular acupuncture, a form of ancient peripheral nerve stimulation (PNS) was documented as early as 200 B.C. in China. The application of electrical stimulation to nerves distal to the dorsal root ganglion or PNS was introduced more than 50 years ago. Due to the lack of dedicated equipment and challenges in reimbursement, the advancement of PNS technology has been rather subdued until the last decade. An implantable PNS device was FDA cleared in 2015 after the first landmark study by Deer et al. This led to a series of fortuitous events paving the way for the recent explosion of PNS innovation in interventional pain medicine. This presentation will review the evolution of peripheral nerve stimulation technology and the accompanying scientific evidence. The topics introduced will help both interventional and non-interventional pain physicians understand the application of peripheral nerve stimulation options for various chronic pain conditions.
