Figure 5.

Mean accuracy in naming untrained words on the Philadelphia Naming Test (PNT) with right cerebellar transcranial direct current stimulation (tDCS) versus sham conditions, at pre-treatment (PreTx), post-treatment (PostTx), and 2 months PostTx. This figure illustrates data from reference 133 but combines data for anodal and cathodal right cerebellar tDCS, which did not have significantly different effects. Both tDCS conditions resulted in greater improvements than sham from PreTx to PostTx, and sustained 2 months later. To see results reported separately for anodal and cathodal tDCS, see reference 111.
