The Effect of Cerebellar tDCS on Static and Dynamic Balance of Inactive Elderly Men

Abstract

The aim of this study was investigating the effect of cerebellar transcranial direct current stimulation (tDCS) on static and dynamic balance of inactive older adults. Twenty-four older adults participated in this study. All participants underwent static and dynamic balance tests. In the Experimental group, anode electrode was positioned at the O point in the cerebellum and cathode electrode was positioned on the left eye socket (FP1). In the control group, the anode and cathode electrodes were positioned at O and FP1 points, respectively, but the current stimulation was stopped after 30 s. Then, the posttest was performed. Data analysis was done using MANCOVA. There was a significant difference between the Experimental and control groups in static balance ( p = .12) and dynamic balance ( p = .18) and the performance was better in the experimental group. It can be concluded that tDCS can improve static and dynamic balance in inactive older adults.
