Brain zaps + coping skills: new hope for fibromyalgia pain?
NCT ID NCT07239427
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether adding a gentle, non-invasive brain stimulation technique called tDCS to a structured pain coping program can help people with fibromyalgia feel better. About 68 adults with fibromyalgia will take part. They will all go through the same program of pain education and exercise, but half will also receive real tDCS and the other half a sham (fake) version. The goal is to see if the real stimulation leads to greater reductions in pain and improvements in daily life.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Must have a prior diagnosis of Fibromyalgia (FM), which must be documented and validated in the patient's medical record. Exclusion Criteria: * Neurological Conditions: History of epilepsy or any other decompensated neurological condition that could contraindicate Transcranial Direct Current Stimulation (tDCS). * Active Pathologies: Presence of other active or recent pathologies (e.g., cancer, fractures, fissures, or severe traumatic accidents of the skull) that could interfere with treatment or evaluation. * Pregnancy: Currently pregnant or planning to become pregnant during the study period. * Metallic Implants: Presence of metallic implants in the skull that may interact with or contraindicate the use of tDCS. * Concurrent Studies: Active participation in another concurrent clinical research study involving treatments for fibromyalgia. * Protocol Adherence: Inability to understand or adhere to the treatment and evaluation protocol.
