Effects of tDCS Versus HD-tDCS for Stroke Rehabilitation

No results posted yet for this study

Summary

The purpose of this study is to assess the changes in language processing of patients with chronic aphasia after receiving non-invasive brain stimulation.Previous research using traditional transcranial direct current stimulation (tDCS) using 2 sponge electrodes has shown that persons with aphasia show more improvement after treatment when that treatment is accompanied by brain stimulation. Traditional tDCS has recently been modified to deliver current to more specific locations in the brain. This new delivery method is called high-definition tDCS (HD-tDCS). It is not known whether traditional tDCS (more diffuse current delivery) or HD-tDCS (more focal current delivery) will be the better approach for enhancing treatment outcomes. To answer this question, computerized speech-language treatment will be administered during the application of the different forms of brain stimulation.
