Figure 2From: Patient-conducted anodal transcranial direct current stimulation of the motor cortex alleviates pain in trigeminal neuralgiaAnalgesic efficacy of anodal transcranial direct currents stimulation (tDCS). tDCS significantly decreases mean pain intensity on the verbal rating scale (VRS) (p < 0.05), while attack frequency (AF) is not significantly different compared to control conditions. Changes of values are expressed as Δ compared to mean values under control conditions in box plots.Back to article page
