Brief Summary
Fibromyalgia is a debilitating pain condition that is characterized by the chronic occurrence of pain affecting the musculoskeletal system, a sensitivity to pressure stimuli, and a low threshold to noxious stimuli. The topography of pain is widespread, although it could be more pronounced in some bodily regions. Besides pain, patients suffer from a wide range of symptoms, including fatigue, anxiety and depression manifestations, and altered quality of life. Facing these debilitating symptoms, the available therapeutic strategies for treating pain and associated manifestations are usually faced with limited efficacy and numerous side effects. A previous pilot trial on fibromyalgia (EXOFIB-1 study) was conducted to evaluate the effects of Exopulse Mollii suit on fibromyalgia has showed beneficial and promising results. The intervention significantly alleviated pain, reduced fatigue, decreased physical and psychosocial impact of the disease, and improved the quality of life of patients with fibromyalgia. However, the observed effect sizes were small to medium. The investigators believe that a stimulation duration extended to six months would yield more positive outcomes and higher effect magnitude.

Outcome Measures
Primary Outcomes (1)
Reduction of functional disability as per the Fibromyalgia Impact Questionnaire (FIQ) right after the intervention (phase 1)
It is an 11-item scale that provides the researchers with a global assessment of the fibromyalgia syndrome, by measuring assesses Quality of Life and measures health status and functional disability and by exploring the impact of fibromyalgia on work, wellbeing, fatigue, sleep, stiffness, anxiety, and depression. FIQ ( Fibromyalgia Impact Questionnaire) 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)
This will be assessed before and after each condition (phase 1, 1 session per condition sham or active stimulation) at Visit 1(Day 0) ,Visit 2 (Day 15), Visit 3( Day 30) and Visit4 (Day 45)
Secondary Outcomes (11)
Reduction of functional disability as per the Fibromyalgia Impact Questionnaire (FIQ) throughout the follow-up period (phase 2)
This will be assessed during the phase 2 visits (6 months of using the EXOPULSE Mollii suit). The visits will take place monthly, starting from visit 5 and throughout visits 6, 7, 8, 9, 10 and 11.
Analgesic effects based on the Visual Analogue Scale (VAS) during phases 1 and 2.
This will be assessed through study completion, an average of 8 months (at Visits 1, 2, 3, 4, 5, 6,7,8,9,10 and 11).
Analgesic effects based on the Brief Pain Inventory (BPI) during phases 1 and 2.
This will be assessed through study completion, an average of 8 months (at Visits 1, 2, 3, 4, 5, 6,7,8,9,10 and 11).
Analgesic effects based on the Pain Catastrophizing Scale (PCS) during phases 1 and 2.
This will be assessed through study completion, an average of 8 months (at Visits 1, 2, 3, 4, 5, 6,7,8,9,10 and 11).
Anti-fatigue effects according to the Visual Analogue Scale (VAS Fatigue) during phases 1 and 2.
This will be assessed through study completion, an average of 8 months (at Visits 1, 2, 3, 4, 5, 6,7,8,9,10 and 11).

Study Arms (2)
Experimental Condition
ACTIVE COMPARATORActive sessions will last 1 hour each. The following parameters will be used for electric stimulation: low frequency (20 Hz), low current intensity (2 mA), with a small pulse width of 25-170 microseconds. These parameters were previously found to be safe in human studies.
Control Condition
SHAM COMPARATORThe control arm will be a sham intervention. The patients will receive a sham stimulation, for which the same Exopulse Mollii suit will be used but the control unit will be programmed to start stimulating for 1 minute then it will shut off which could enable cutaneous sensations that mimic the active condition, aiming to achieve an effective blinding integrity. There is no risk related to the sham intervention since it consists of applying the same parameters used for the active session (low frequency: 20 Hz; current intensity: 2 mA; pulse width ranging from 25 to 170 µs) but for a shorter duration of time (1 minute).
Interventions
Exopulse Mollii suit is a new assistive device that has been developed by Exoneural Network (initially Inerventions AB), a Swedish med-tech company. Exopulse Mollii suit is a full-body garment with integrated 58 electrodes that can transcutaneously stimulate several groups of muscles. The device is CE labelled and is intended to use for reducing spasticity and improving blood circulation. The outfit is very easy to put on, it can be used for one hour every day and the analgesic effects last 24 hours or more. EXOPULSE Mollii suit consists of transcutaneous stimulation of several muscles by means of a feeble electric current (i.e., low frequency \~20 Hz, low-intensity 2mA), aiming to reduce pain. This treatment method theoretical background primarily refers to the theory of gate control. Based on this theory, the stimulation of large proprioceptive fibers would inhibit the nociceptive information transmitted by small fibers.
It consists of applying the same parameters used for the active session (low frequency: 20 Hz; current intensity: 2 mA; pulse width ranging from 25 to 175 µs) but for a shorter duration of time (1 minute).
Eligibility Criteria
You may qualify if:
- Patients aged between 18 and 75 years, with a definite diagnosis of fibromyalgia according to the American College of Rheumatology (ACR) 2010 criteria, set for at least three months

- Patient with somatic or psychiatric diagnoses other than anxiety and depression (e.g., arrhythmias, uncontrolled epilepsy, other diseases causing osteoarticular and muscular pain)
- Any change in the pharmacological therapy in the last three months
- Introduction of a medical device other than Exopulse Mollii suit during the study period
