Auricular Neuromodulation in Veterans With Fibromyalgia: A Randomized, Sham-Controlled Study
VA Office of Research and Development
Summary
PENFS (percutaneous electrical nerve field stimulation) is an FDA-cleared acupuncture-like therapy applied to the external ear targeting several cranial nerve branches including the auricular branch of the vagus nerve to improve pain, physical function, and reduce symptoms of opioid withdrawal. PENFS has been previously shown to provide improvements in fibromyalgia, a difficult to treat chronic pain syndrome, which correlate with changes observed using a special kind of MRI called resting state functional connectivity MRI (rs-fcMRI) that evaluates brain activity at rest. The goals of this study are to rigorously test the initial promising results of PENFS in a much larger group of Veterans suffering from fibromyalgia and to identify potential mechanisms of PENFS effects. Further developing non-pharmacologic therapies for pain can help to improve quality of life and function for those suffering from fibromyalgia and decrease reliance on opioids and other drugs that have numerous side effects for individuals suffering from chronic pain.
Description
BACKGROUND: In the setting of the opioid epidemic, it is crucial to develop and assess non-pharmacologic treatments for pain and understand underlying mechanisms. In the present investigation, the investigators assess a novel non-pharmacologic approach to chronic pain treatment in Veterans suffering from fibromyalgia (a notoriously difficult to treat pain syndrome that affects 5-10 million Americans and disproportionately affects those returning from the Gulf War), utilizing brain imaging as a biomarker and heart rate variability (HRV) to assess a vagal mechanism. Preliminary results from prio…
