NCT04890964

Brief Summary

This study aims to map the impact of anodic transcranial direct current stimulation (tDCS) for prolonged home use applied to the primary motor cortex and the left dorsolateral prefrontal córtex (DLPFC), compared to the respective treatments simulated in fibromyalgia.

Eligibility Criteria

Age30 Years - 65 Years
Sexfemale(Gender-based eligibility)
Gender Eligibility DetailsWe have chosen women over men, due to the prevalence of the disease that we are researching and also because the symptoms characteristics are more homogeneous.
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Women aged 30 to 65 years; who can read and write, with a confirmed diagnosis of FM according to the criteria of the American College of Rheumatology (2010-2016). Pain score equal to or greater than six on the Numeric Pain Scale (NPS 0-10) on most days in the last 3 months.

You may not qualify if:

  • Living outside Porto Alegre area and pregnancy.
  • Contraindications to TMS and tDCS: metallic implant in the brain; medical devices implanted in the brain, cardiac pacemaker; aneurysmal clip; metallic cochlear prosthesis, ear implants, and non-removable hearing aids; infusion pumps (including implantable); cranial halos. Pregnant women, shift work, use of exogenous melatonin, history of alcohol or drug abuse in the last 6 months, neurological pathologies, history of head trauma or neurosurgery, decompensated systemic chronic diseases, chronic inflammatory diseases (lupus, rheumatoid arthritis, Reiter's syndrome), personal history of cancer, past or under treatment.
