Safety of cathodal transcranial direct current stimulation early after ischemic stroke

According to the hypothesis of interhemispheric inhibition, the unaffected motor cortex (M1UH) may excessively inhibit the motor cortex of the affected hemisphere (M1AH) in subjects with stroke leading to exaggeration of the contralateral upper limb paresis. TDCS can be used to either inhibit M1UH, excite M1AH, or both. Typically, anodal tDCS increases brain excitability and cathodal tDCS (ctDCS) has the opposite effect [1].
