Design outcomes

Primary

MeasureTime frame
Completion of the study after 9 weeks: (I) significant improvement of attention, proven by a lower failure rate in the attention network test and (II) significant attenuation of pain related evoked potentials in the EEG after active tDCS and tRNS compared to sham stimulation.

Secondary

MeasureTime frame
Completion of the study after 9 weeks: (I) Significant improvement of depression rating in the Hospital Anxiety ans Depression Scale (HADS) and the Modified Fatigue Impact Scale (MFIS) and (II) significant reduction in pain perception in the Brief Pain Inventory (BPI) after active tDCS and tRNS compared to sham stimulation.
