Brief summary (from the registry)

Fibromyalgia is a public health condition, which causes great functional disability. Conventional treatment modalities have been shown a very poor therapeutic response, in that most individuals end up becoming poly-medicated and refractory to treatment. Non-pharmacological techniques with promising effects on the syndrome symptoms include both hypnotic analgesia and the transcranial direct-current stimulation (tDCS). Giving the treatment limitations of this syndrome its important to better understand the pain processess in fibromyalgia and treatments effect. This project was developed in order to evaluate the synergistic effect of a hypnotic analgesia suggestion associated with tDCS over pain levels and cortical excitability in individuals with fibromyalgia over a nociceptive stimulation pattern.
