Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Technological advances and non-invasive techniques to modulate brain function have been developed, including transcranial Direct Current Stimulation (tDCS). Basically, electrodes are placed on the brain regions to stimulate or inhibit it. Subsequently, a continuous electrical current (0.4-2 mA) is imposed, for a period of 3-20 minutes, to modify cortical excitability. Few are the research groups that work on the topic of primary dysmenorrhea and the use of tDCS as the focus of study. Preliminary studies associated the use of tDCS with pain reduction, but the outcomes of physical and behavioral function needs further investigation.

Active-tDCS

A constant current (anodic) of 2mA will be applied for 20 minutes over the Primary motor cortex (M1).

Group Type EXPERIMENTAL

Active Transcranial Direct Current Stimulation

Intervention Type DEVICE

For electrode placement, the criteria used by the 10/20 electroencephalography system will be obeyed and the electrodes will be positioned over Primary motor cortex, C3 area for the anode and Fp2 (contralateral supraorbital area) for the cathode electrode. A constant current of 2mA will be applied for 20 minutes.

Sham-tDCS

A constant current (sham) of 2mA will be applied on the Primary motor cortex, but the stimulator will be turned off after 30 seconds .

Group Type SHAM_COMPARATOR

Sham Transcranial Direct Current Stimulation

Intervention Type DEVICE

For electrode placement, the criteria used by the 10/20 electroencephalography system will be obeyed and the electrodes will be positioned over primary motor cortex, C3 area for the anode and Fp2 (contralateral supraorbital area) for the cathode electrode, but the stimulator will be turned off after 30 seconds of stimulation.
