Effects of taVNS on Fibromyalgia Pain

Study Purpose

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.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

 No
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

More Inclusion & Exclusion Criteria

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 self-reported. 2. 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). 3. Presence of implanted cranial electronic medical devices (e.g., cochlear implants). 4. 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).

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

 NCT06193317
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Arms & Interventions

Arms

Experimental: Active taVNS

TaVNS will be administered by an earset, with conductive eartips placed on the auricular concha of the ears, connected to a stimulator, and during active stimulation, we stimulate both the cymba conchae and external auditory canal of both left and right ears with the following parameters: 30Hertz (Hz), 200-250 us, and with adjustable intensity for 60 min for 16 sessions.

Sham Comparator: Sham taVNS

Sham condition will have the same device, with an earset, and conductive eartips placed in the same location of the active stimulation; however during 60 min for 16 sessions there will be no current and the device will be turned off.

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).
