EMDR combined with gentle brain stimulation (tDCS) for fibromyalgia
Augmentation of EMDR With Transcranial Direct Current Stimulation (tDCS) in the Treatment of Fibromyalgia: a Double-blind Randomized Controlled Trial
This project will test whether adding non-invasive brain stimulation (tDCS) to EMDR helps people with fibromyalgia who also have trauma-related symptoms, depression, or anxiety.

What this trial studies
Researchers in Barcelona will randomize eligible patients to receive EMDR combined with active tDCS, EMDR with sham tDCS, or treatment as usual. tDCS is applied during EMDR sessions to modulate brain activity related to pain and stress while EMDR targets trauma-related memories. The trial measures pain intensity, depressive and anxiety symptoms, and trauma-associated symptoms after therapy and at follow-up. Comparisons will show whether active tDCS enhances or prolongs EMDR benefits beyond EMDR with sham stimulation or usual care.
Who should consider this trial
Good fit: Adults 18–70 with diagnosed fibromyalgia who report an average pain score of at least 4/10 in the prior two weeks, have current trauma-related symptoms plus depressive and/or anxiety symptoms, and are on stable medication for at least two weeks.
Not a fit: Patients with autoimmune or serious neurological/medical diseases, bipolar or psychotic disorders, active suicidal ideation, recent substance dependence, recent EMDR (within two years), pregnancy, metallic head implants, skin sensitivity conditions, pending litigation, or those without trauma-related symptoms are unlikely to qualify or receive benefit.
Why it matters
Potential benefit: If successful, the combination could produce larger and longer-lasting reductions in pain, mood symptoms, and trauma-related distress for people with fibromyalgia.
How similar studies have performed: EMDR is an established therapy for PTSD and small studies suggest benefit in fibromyalgia, and tDCS has shown modest effects on pain, but combining EMDR with tDCS is a relatively new approach with limited prior data.
