The effectiveness of direct electrical stimulation of the brain on visual perceptual coordination in children with learning disabilities

The purpose of this study was to the effectiveness of transcranial direct current stimulation (tDCS) on perceptual visual coordination in students with learning disabilities.

It was a quasi-experimental study with pretest, posttest and control group design. The statistical population of the study included all students with learning disabilities in Dezful in 2020. The sample size consisted of 30 students with learning disabilities who were selected by available sampling method and according to the inclusion and exclusion criteria. The experimental group received ten sessions of ten minutes per week.The applied questionnaires in the study included Visual Critical Scale of the Bender-Gastalt. Data were analyzed using univariate analysis of SPSS version 22 software.

The results showed that transcranial direct current stimulation on perceptual visual coordination in the learning disabilities (p<0/001).

According to the findings of the present study, transcranial direct current stimulation can be suggested as an efficient method in order to reduction perceptual visual coordination in the learning disabilities.
