SWIFT-RELIEVE : Simultaneous Treatment of Widespread Pain In Fibromyalgia and PTSD: Randomized Evaluation of Live vs. Inactive Electrical VNS With PE-PC

Summary

Fibromyalgia (FM) pain and PTSD are highly prevalent and comorbid with associated increased risk of negative physical and mental health outcomes, including higher risk for opioid use and suicide. This project is designed to determine the effects of a 4 week trial of a device for pain management \[transauricular vagus nerve stimulation (taVNS)\] on pain interference and intensity \[Pain, Enjoyment, and Activity General Scale (PEG)\] and PTSD. The investigators will also examine how this impacts the Veterans by examining heart rate variability (HRV) as a stress response related biomarker. The investigators plan to randomize 180 Veterans (estimate up to 360 enrolled) with co-morbid FM and PTSD across pain integrated care and PTSD sites in this prospective study and compare: 1) active taVNS for pain + Prolonged Exposure in Primary Care (PE-PC) and 2) sham taVNS + PE-PC. Study includes 4 weeks of randomized treatment and 4 weeks of voluntary open label treatment. Veterans are assessed (self report \& interview measures, heart rate variability by wearable device) at Intake, Baseline/Post Run-In, Week 2, Week 4, Week 8 and 4 month follow-up. The investigators plan to retain data after the study for potential future use in research.
