Effects of transcranial direct current stimulation (tDCS) on balance improvement: a systematic review and meta-analysis.

Transcranial direct current stimulation (tDCS) has emerged as a promising therapeutic tool to improve balance and optimize rehabilitation strategies. However, current literature shows the methodological heterogeneity of tDCS protocols and results, hindering any clear conclusions about the effects of tDCS on postural control. Evaluate the effectiveness of tDCS on postural control, and identify the most beneficial target brain areas and the effect on different populations.
