Battlefield Acupuncture: An Emerging Method for Easing Pain
Pain medications, including opioids, often have limited efficacy and may impose unwanted adverse effects. These limits explain the Department of Defense and the Veterans Administration's interest in nonpharmacologic interventions including acupuncture.2 As traditionally practiced, acupuncture involves a complex assessment and individualized treatment by trained providers (300 hrs required for physicians), which are barriers to widespread implementation in military and veteran settings.
In 2001, Niemtzow3 developed “battlefield acupuncture” (BFA), a form of auriculotherapy where a sequence of gold aiguille semipermanent needles (Sedatelec, Irigny, France) are placed at up to five specific sites in one or both ears. Battlefield acupuncture is purported to influence central nervous system pain processing through its effects on a somatotopic organization of the body represented in the auricle. It has been suggested that auricular therapies cause the release of β-endorphins to elicit short-term analgesia or anti-inflammatory cytokines for long-term effects.4 The BFA needles (more accurately described as tiny conical darts) pierce the ear in designated locations in a particular order (Figs. 1 and 2 show the technique and the locations of needle placement). They stay in place until they fall out typically within 3–4 days.2
Although there is some support for auricular therapy in general, the evidence base for BFA is relatively meager.2,4 Regardless, the Defense and Veterans Center for Integrative Pain Management and the Veterans Health Administration National Pain Management Program Office recently completed a 3-yr $5.4 million acupuncture education and training program, which deployed certified BFA trainers to receptive Department of Defense and Veterans Administration medical centers. Over 2800 providers were trained to provide BFA. At the author's Veterans Administration facility, approximately 60 practitioners have been trained, producing approximately 2500 patient BFA encounters in the past 2 yrs. In the first author's experience with nearly 30 veterans, BFA has reduced pain for those with headaches, acute and chronic back and musculoskeletal pain, and neuropathic pain.
Besides obvious questions regarding the mechanisms of action, the comparative efficacy, and duration of effects, the Department of Defense and Veterans Health System embrace of BFA presents an opportunity to study the adaption and implementation of this most fascinating complementary technique into traditional western practice. If the promise of BFA holds true, it will add an important treatment option in physiatrists' arsenal to treat acute and chronic pain.
