Physical Performance and Analgesic Effects of tDCS in Primary Dysmenorrhea

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.

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.
