Efficiency of Repetitive Transcranial Direct Current Stimulation of the Dorsolateral Prefrontal Cortex in Disorders of Consciousness: A Randomized Sham-Controlled Study

Figure 2

Overview of experimental structure. (a) 15 patients were equally divided into 3 groups as group A (left anodal tDCS), group B (right anodal tDCS), and group C (sham tDCS). Stimulation sites of each group were marked on the international 10–20 system. The anode is colored red, the cathode blue. (b) Stimulation protocol. One session per day, for a total of 10 sessions in a 2-week period. Evaluations were performed at baseline (T0), immediately after stimulation (T1), and 3 months later.
