The efficacy of combining speech training with transcranial direct current stimulation on patients with non-fluent aphasia after stroke

This study will provide a theoretical basis for the treatment of post-stroke aphasia with transcranial direct current Stimulation(tDCS) by observing the efficacy of combining speech training with transcranial direct current Stimulation on patients with non-fluent aphasia after stroke. Thirty four patients with post-stroke non-fluent aphasia who met the inclusion criteria were enrolled. All patients were informed of the trial and signed informed consent. Patients were randomly divided into an experimental group and a control group, each consisting of 17 patients. Linear regression models were used to assess within-person differences within conditions for each outcome. Post-test scores were considered as dependent variables explained by condition and pretest scores as the independent variables. Results showed that participants in the speech training with tDCS experimental condition reported significant changes in The Western Aphasia Battery (WAB), The Boston Diagnostic Aphasia Examination (BDAE), Arabic Version of the Communication Checklist (CCC2)scores from pre-intervention to post-intervention.
