Detailed Description

This study aims to map the impact of anodic tDCS for prolonged home use applied to the primary motor cortex and the left dorsolateral prefrontal córtex (DLPFC), compared to the respective treatments simulated in fibromyalgia, targeting the outcomes of the following axes: (1) pain intensity and functional capacity; (2) psycho cognitive functions; (3) neurophysiological markers; (4) biological rhythm markers; (5) to map the potential of neurophysiological markers, biological rhythm and history of trauma in childhood and adolescence in functional capacity, depressive symptoms and working memory tests.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

30 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description

Time Frame: Up to 60 minutes before and after tDCS stimulation
response on the Numeric Verbal Scale (NPS) from 0-10 during the conditioning stimulus
Up to 60 minutes before and after tDCS stimulation

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
