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.
Inclusion Criteria: 1. Older than 18 years old. 2. 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). 3. must have the ability to feel sensation by Von-Frey fiber on the forearm. 4. Able to provide informed consent to participate in the study. Exclusion Criteria: 1. 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…
