The clinical application of transcranial direct current stimulation in patients with cerebellar ataxia: a systematic review.

tDCS could be considered an effective approach to promote plasticity in patient with cerebellar ataxia with significant motor effects. Future studies, with larger sample sizes are needed in order to evaluate the effective tDCS benefits on motor functionality. Due to the limited number of studies available so far, conclusions on the effectiveness of the reported approaches are premature.
