EEG Prediction and Clinical Efficacy of tDCS in Fibromyalgia. (FM-TDCS-PREDIC)
Clinical Efficacy of tDCS in Fibromyalgia: A Controlled Clinical Trial and Analysis of Electrophysiological Biomarker Predictors.
The purpose of this randomized controlled trial is to investigate the non-inferiority, and possible superiority, of a high-dose home-based tDCS protocol compared with a conventional home-based protocol, and to assess its cost-effectiveness, in patients with fibromyalgia.
As complementary goals, we aim to assess the predictive value of baseline EEG for clinical response to high-dose home-based tDCS treatment; and to describe the effectiveness of a high-dose home-based protocol applied to the motor cortex (M1) versus the dorsolateral prefrontal cortex (DLFPC) in patients with fibromyalgia.

Inclusion Criteria:
- Patients who meet the diagnostic criteria described by the American College of Rheumatology (Wolfe et al., 2016):
- Widespread Pain Index (WPI) ≥7 and Symptom Severity Scale (SSS) score ≥5 or a WPI score of 4-6 and SSS ≥9

- Volunteer to participate and sign the specific informed consent form for this study.
Exclusion Criteria:
- Presenting with immune system disorders or comorbidities that explain the main symptoms of fibromyalgia: rheumatoid arthritis, lupus, autoimmune, neurological, and oncological disorders.
- Presenting with any uncompensated clinical condition such as ischemic heart disease, kidney disease, or liver disease.
- Presenting with dermatological conditions, such as allergic skin reactions at the electrode sites, psoriasis, etc.
- Any exclusion criteria established by clinical guidelines on non-invasive brain stimulation (Woods et al., 2016):
- Metallic implants or head injuries, any electronic device such as cochlear implants or cardiac pacemakers.
- Brain stimulation within the last 6 months.
- A clinical or family history of epilepsy.
- Having any structural lesion (for example, any structural neurological condition or more subcortical lesions than would be expected for their age, or having suffered a stroke affecting the stimulated area or connected areas) or any other clinically significant abnormality that could affect safety, participation in the study, or confound the interpretation of the study results, as determined by the investigator.
- History of drug or alcohol abuse during the study or in the 3 months prior (except for nicotine).

Kokeellinen: High-dose home-tDCS M1
tDCS administered at home using a high-dose protocol targeting the primary motor cortex.
|
Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique in which a weak direct current (2 mA) is applied to the scalp via electrodes. The anode will be applied to C3 (primary motor cortex) and the cathode to Fp2 (contralateral anterior frontal region). The application of tDCS will be carried out at home in this group. Each session will consist of 20 minutes of stimulation. Dose: 3 weeks, daily. (1) 1st week - 3 times per day; (2) 2nd Week - 2 times per day; (3) 3rd week - 1 time per day (total of 42 sessions). |
|
Active Comparator: Conventional home-tDCS
tDCS administered at home using a conventional stimulation protocol targeting the primary motor cortex.
|
Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique in which a weak direct current (2 mA) is applied to the scalp via electrodes. The anode will be applied to C3 (primary motor cortex) and the cathode to Fp2 (contralateral anterior frontal region). The application of tDCS will be carried out at home in this group. Each session will consist of 20 minutes of stimulation. Dose: 4 weeks, from Monday to Friday. 1 time per day (total of 20 sessions). |
|
Kokeellinen: High-Dose home-tDCS DLPFC
tDCS administered at home using a high-dose stimulation protocol targeting the dorsolateral prefrontal cortex.
|
Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique in which a weak direct current (2 mA) is applied to the scalp via electrodes. The anode will be applied to F3 (left dorsolateral prefrontal cortex) and the cathode to F8 (right ventrolateral prefrontal cortex). The application of tDCS will be carried out at home in this group. Each session will consist of 20 minutes of stimulation. Dose: 3 weeks, daily. (1) 1st week - 3 times per day; (2) 2nd Week - 2 times per day; (3) 3rd week - 1 time per day (total of 42 sessions). |
