Use of Transcranial Direct Current Stimulation (TDCS) in an Active Pain Coping Program for Patients With Fibromyalgia: A Randomized Control Trial.
The trial is designed to determine the added effect of active transcranial direct current stimulation (tDCS) when combined with a multimodal Active Pain Coping Program in individuals with fibromyalgia. The primary objective is to compare the effectiveness of active versus sham tDCS when both are delivered to the same standardized multimodal intervention. All participants will undergo an identical treatment sequence consisting of 8 sessions of Pain Neuroscience Education (PNE), followed by 5 consecutive daily sessions of either active or sham tDCS, and 18 sessions of therapeutic exercise (TE). Active tDCS will be administered over the primary motor cortex (M1) and orbitofrontal region for 20 minutes at 2 mA. The sham procedure will replicate the electrode placement and brief initial stimulation to ensure blinding, with no active current thereafter. Secondary outcomes will examine changes in pain intensity, central pain processing, psychological variables, and physical function.
