About this study

Official title: The Effects of EXOPULSE Mollii Suit on Fibromyalgia Syndrome in Patients With Fibromyalgia (EXOFIB 2): A Sham Controlled Randomized Double-Blind Trial

The goal of this clinical trial is to demonstrate the improvement of fibromyalgia syndrome obtained following active stimulation compared to sham, with diminished functional disability and improved health status using Exopulse Molli suit stimulation. The main questions it aims to answer are:

Evaluation of pain, fatigue, mood and quality of life changes observed after active stimulation in comparison to sham.

Improvement of fibromyalgia syndrome as per the Fibromyalgia Impact Questionnaire (FIQ)

Study subjects will participate in:

A randomized sham controlled double-blind trial to demonstrate the improvement of pain, quality of life, fatigue and mood in adult patients with fibromyalgia following a 2-week intervention of "active" versus "sham" Exopulse Mollii suit. A 2-week washout period should be enough to prevent a potential carry over effect. After this phase (phase 1), a second open label phase (phase 2) will be proposed for patients to understand the effects of Exopulse Mollii suit employed for 4 weeks (7 sessions per week) on the studied outcomes.

    We designed a randomized sham controlled double-blind trial to demonstrate the improvement of pain, quality of life, fatigue and mood in adult patients with fibromyalgia following a 2-week intervention of "active" versus "sham" Exopulse Mollii suit. A 2-week washout period should be enough to prevent a potential carry over effect. After this phase (phase 1), a second open label phase (phase 2) will be proposed for patients to understand the effects of Exopulse Mollii suit employed for 4 weeks (7 sessions per week) on the studied outcomes.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Fibromyalgia Impact Questionnaire (FIQ)

    It is an 11-item scale that assesses health status and functional disability by exploring the impact of fibromyalgia on work, wellbeing, fatigue, sleep, stiffness, anxiety, and depression. FIQ scores can range from 0 to 100, with higher scores reflecting worse health status. Scores could be used to classify fibromyalgia as mild (scores: 0-38), moderate (scores: 39-58), and severe (scores: 59-100)

    Measured: This to be assessed at baseline, then at week 2, week 4, week 6, week 8 and week 12.

Secondary outcomes (7)
  1. Brief Pain Inventory (BPI)

    will be used to assess pain severity (4 items) and pain interference (7 items). BPI items are rated on a 10-point scale running from 0 (no pain/does not interfere) to 10 (pain as bad as the participant can imagine/interferes completely).

    Measured: This to be assessed at baseline, then at week 2, week 4, week 6, week 8 and week 12.

  2. Pain Catastrophizing Scale (PCS)

    Pain Catastrophizing Scale (PCS) will be employed, which is a valid and reliable scale that includes 13 items assessing the presence and severity of feelings or thoughts that emerge when experiencing pain. Each item is rated on a 5-point Likert scale ranging from 0 (not at all) to 4 (all the time). It is possible to calculate a total and three subscale scores (i.e., helplessness, magnification, and rumination)

    Measured: This to be assessed at baseline, then at week 2, week 4, week 6, week 8 and week 12.

  3. Quality of life as per the Short Form 36 Health Survey (SF-36)

    It is a generic survey that contains 36 items which assess the quality of life and yield eight dimensions: physical functioning, physical role, emotional role, bodily pain, general health, vitality, social functioning, and mental health. The score of each dimension ranges from 0 to 100, with higher scales implying better health status.

    Measured: This to be assessed at baseline, then at week 2, week 4, week 6, week 8 and week 12.

  4. Visual Analogue Scale for Pain

    Pain will be measured using a visual analog score from 0 to 10, 0 being no pain, to 10 being the worst possible pain.

    Measured: This to be assessed at baseline, then at week 2, week 4, week 6, week 8 and week 12.

  5. Visual Analogue Scale for Fatigue

    Fatigue will be measured using a visual analog score from 0 to 10, 0 being no fatigue, to 10 being the worst possible fatigue

    Measured: This to be assessed at baseline, then at week 2, week 4, week 6, week 8 and week 12.

  6. Hospital Anxiety and Depression Scale (HADS)

    It is a 14-item generic scale with good psychometric properties and consists of seven items assessing anxiety and seven others assessing depression. Scores can range from 0 to 21 on each subscale, with higher scores indicating worse symptomatology.

    Measured: This to be assessed at baseline, then at week 2, week 4, week 6, week 8 and week 12.

  7. Clinical Global Impression (CGI)

    Evaluation of overall Clinical improvement will be done using the 7-point Clinical Global Impression (CGI). Patient will fill a questionnaire that will address their clinical situation as follows:

    Very much improved. Much improved. Slightly improved. No change. Slightly worse Much worse. Very much worse The score will range from 1-7, 1 being the best clinical outcome and 7 the worst.

    Measured: This to be assessed at week 2, week 6 and week 12.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 8 Sep 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United Arab Emirates. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Fibromyalgia Impact Questionnaire (FIQ) (time frame: This to be assessed at baseline, then at week 2, week 4, week 6, week 8 and week 12.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06226376, which also lists 40 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Sep 2025.
