Effects of Combined Treatment With tDCS & Cognitive Training in Patients

Status Completed

Clinical Trial Summary

Chronic pain represents an important health problem responsible for decreases in quality of life, and is associated with great negative impact in society and economy. In many cases, its treatment does not reach therapeutic success causing health professionals and patients dissatisfaction. Chronic pain is also associated with somatization, hopelessness and catastrophizing thinking. These information processing includes sensorial, emotional and cognitive-appraisal thinking, which manifests the working of neural networks at cortical and sub-cortical levels. Attention and memory are a central aspect in the processing of pain modulation. Like in addictions (e.g. smoking, alcohol), chronic pain may debut with displacement in the focus of attention and alterations in the sensorial processing in the incentive-motivation tests. Considering that other studies have indicated that experimental and clinical pain is capable of modulating cognitive activities such as attention,memory and expectation, in this study the investigators will test whether cognitive training, tDCS, or the combination of both interventions decrease cognitive deficits associated with Fibromyalgia

Clinical Trial Description

Will be included women aged between 18 and 65 years, chronic pain fibromyalgia according to the criteria of the American College of Rheumatology, pain unresponsive to analgesics such as paracetamol, acetylsalicylic acid, ibuprofen, Carisoprodol, Zanaflex (Tizanidine) and Codeine and give informed consent to participate after initial evaluation. Primary outcome is to Evaluate whether the tDCS associated with cognitive retraining technique is able to modulate attentional bias in fibromyalgia patients. Secondary outcomes are: compare the effect of active tDCS and sham in: Assessed with the Visual Analog Scale for 8 days, Functional capacity, Conditional pain modulation (CPM), Maximal Heat Pain tolerance,Catastrophic thinking,Serum levels of Brain Derived Neurotrophic Factor (BDNF), Beck Depression Inventory, forward and backward digit span( WAIS),Pittsburgh sleep quality and State-Trait Anxiety Inventory (STAI) test. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
