Auricular Acupuncture for Autonomic Balance and Pain in Fibromyalgia

June 6, 2026 updated by: Antonello Lovato, Italian Association for the Research and the Scientific Update

Impact of Semi-Permanent Auricular Acupuncture on Autonomic Balance and Pressure Pain Threshold in Patients With Fibromyalgia: A Longitudinal Study

This longitudinal study evaluates the effects of semi-permanent auricular acupuncture on the Autonomic Nervous System (ANS) activity and pressure pain threshold in adult female patients (aged 35-64) diagnosed with Fibromyalgia according to the 2016 American College of Rheumatology (ACR) criteria. The study aims to investigate how a 5-week treatment cycle influences cardiac autonomic regulation and pain sensitivity

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Participants will undergo a series of 5 weekly sessions of auricular acupuncture using semi-permanent needles (Pyonex Seirin 0.9 mm). The needles will be applied to specific auricular points: Point Zero, Shen Men, Thalamus, and Master Cerebral Point. Each application will last for 72 hours, with the patient performing the removal

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

Confirmed diagnosis of Fibromyalgia by a Rheumatologist according to the 2016 ACR (American College of Rheumatology) criteria.

  • Female sex.
  • Aged between 35 and 64 years.
  • Signed written informed consent.

Exclusion Criteria:

  • Presence of cardiac rhythm disorders such as permanent Atrial Fibrillation.
  • Patients with Pacemakers.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change from Baseline in Autonomic Nervous System (ANS) Balance via LF/HF Ratio
Time Frame: Baseline (T0), Week 1 (T1), Week 2 (T2), Week 3 (T3), Week 4 (T4), and Follow-up at Week 8 (T5).
Evaluated through Photoplethysmography (PPG) using the PPG Stress Flow device. The autonomic nervous system balance is expressed specifically by the Low Frequency to High Frequency (LF/HF) ratio. Other spectral parameters (SDNN and HF power) are collected simultaneously to support the comprehensive Heart Rate Variability (HRV) analysis. All measurements are taken immediately before each acupuncture session.
Baseline (T0), Week 1 (T1), Week 2 (T2), Week 3 (T3), Week 4 (T4), and Follow-up at Week 8 (T5).

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change from baseline in Pressure Pain Threshold (PPT)
Time Frame: Baseline (T0), Week 2 (T2), Week 4 (T4), and Week 8 (T5)
Measured using the Force Ten FPX 25 Algometer to determine the minimum pressure perceived as painful. Measurements are taken at three specific body points: Trapezius (GB21), Lateral Epicondyle (LI11), and below the knee (ST36). Measurements are taken immediately before the acupuncture session
Baseline (T0), Week 2 (T2), Week 4 (T4), and Week 8 (T5)

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
