Effectiveness of Transcranial Direct Current Stimulation (tDCS) on working memory and Reading Level in Students with Disability of Reading

The purpose of this research is  investigation of the transcranial direct current stimulation tDCS, effect on working memory and reading levels of students with Disability of  Reading.

In this semi-experimental study, the statistical population has been all students of elementary school who had Disability of  Reading in Sirjan city in school year of 95-96 that Out of this number, 20 subjects, including 6 boys and 14 girls in the first and second grades, were selected through the sampling method.All subjects were tested in two groups of 10 experimental and  sham groups for 10 sessions and each session for 20 minutes. In the test, the anode electrode on the DLPFC region and the cathode electrode placed on the opposite side shoulder In order to investigate the effect of electrical stimulation, the experimental group exposed to stimulation.

All subjects evaluated before intervention and after intervention by N-back and Disability of  Reading  tests. The results of acquisitive data analysis by using of single-variable and multi-variable covariance showed that tDCS causes improving of working memory and readability of students with Disability of  Reading.

The acquisitive findings indicates that the protocol of tDCS applying causes the network cortical excitability increase of brain regions that play an important role in working memory. It also has potential abilities for improving the effectiveness of rehabilitation in children with Disability of  Reading.
