Overview
Transauricular vagus nerve stimulation (taVNS) is a newer delivery system, using a non-invasive stimulation device placed at the ear's concha. TaVNS is a portable, safe, and low-cost intervention, and according to some studies, taVNS may influence nociception and pain perception, which can lead to potential applications for various painful illnesses, including fibromyalgia (FM). This trial aims to investigate the clinical effects of taVNS on pain control in FM subjects.
Interventions
- Device Transauricular vagus nerve stimulation (taVNS)
Transauricular vagus nerve stimulation (taVNS) is a simple technique in which small surface electrodes are placed over the skin of the ear that are thought to be innervated by the auricular branch of the vagus nerve (ABVN).
Primary outcome measures
- pain severity using the Brief Pain Inventory (BPI pain) [Time frame: From Baseline to Visit 19 (at 4 weeks)]
Eligibility criteria
Inclusion criteria
- Older than 18 years old.
- Diagnosis of FM pain according to the American College of Rheumatology (ACR) 2010 criteria (existing pain for more than six months with an average of at least 3 on a 0-10 VAS scale).
- must have the ability to feel sensation by Von-Frey fiber on the forearm.
- Able to provide informed consent to participate in the study.
Exclusion criteria
- Subjects who have unstable medical conditions (e.g., uncontrolled diabetes, uncompensated cardiac issues, heart failure, or chronic obstructive pulmonary disease) or who have functional deficits, as self-reported.
- history of substance abuse within the past six months as self-reported (if the subject reports a history of substance abuse, we will confirm using the Diagnostic and Statistical Manual of Mental Disorders (DSM-V) criteria).
- Presence of implanted cranial electronic medical devices (e.g., cochlear implants).
- pregnancy (as the safety of taVNS in the pregnant population (and children) has not been assessed (though the risk is non-significant), we will exclude pregnant women (and children). Women of child-bearing potential will be required to take a urine pregnancy test during the screening process and every two weeks of stimulation).
Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
