Sponsor's own description

Pain is a public health condition, which causes great functional disability. Its consequences pervade the personal and social life of the patient, leading to significant changes in their interpersonal relationships, including work, family and social spheres, reducing the ability to perform daily activities. Conventional treatment modalities have been show a very poor therapeutic response, in that most individuals end up becoming polymedicated patients and refractory to treatment. Among non-pharmacological techniques with promising analgesic effects it includes both the hypnotic analgesia and the transcranial stimulation of direct current (tDCS).
