Effect of Transcranial Direct Current Stimulation on Balance in Individuals with Stroke: A Systematic Review and Meta-Analysis

Background and purpose: Postural instability is a disabling consequence of stroke. Transcranial direct current stimulation (tDCS) has been proposed as an adjunctive intervention for rehabilitation; however, the efficacy of different stimulation parameters remains unclear. This study aimed to investigate the effect of tDCS on balance after stroke and identify its potential moderators.
