Efficacy and Neural Mechanisms of Transcranial Direct Current Stimulation Targeting the Supplementary Motor Area for the Treatment of Subacute Post-stroke Aphasia

2026年7月15日 更新者:Panpan Hu, MD、The First Affiliated Hospital of Anhui Medical University

Study on the Efficacy and Neural Mechanisms of Transcranial Direct Current Stimulation Targeting the Supplementary Motor Area for the Treatment of Subacute Post-stroke Aphasia

This study aims to investigate the efficacy of transcranial direct current stimulation (tDCS) in patients with post-stroke aphasia (PSA) and to explore its potential neural mechanisms. The study will recruit PSA patients and provide them with 14 tDCS sessions over 7 days, along with speech therapy. Language Behavior Scale scores and resting-state functional MRI scans will be collected before and after the intervention. In addition, a retrospective comparison will be conducted of language function and resting-state fMRI changes in a group of PSA patients who received only speech therapy; these patients did not undergo any physical intervention but received only speech therapy. Changes in Language Behavior Scale scores and functional connectivity (FC) before and after treatment in the speech therapy-only group will be analyzed and compared with those in the tDCS intervention group.

武器和干预

参与者组/臂
干预/治疗
实验性的:tDCS group
PSA patients enrolled in the tDCS group received tDCS treatment twice daily for 7 consecutive days, along with 7 days of speech-language therapy. The current intensity was 2 mA, and each treatment session lasted 20 minutes.
As a non-invasive brain stimulation technique, tDCS offers advantages such as convenience, safety, and low cost. Its mechanism of action involves regulating neuronal activity in the brain by applying a weak direct current to the scalp.
无干预:The speech-language therapy group
The speech-language therapy group received only 7 days of speech-language therapy.

The Aphasia Battery of Chinese (ABC) is a standardized Chinese adaptation of the Western Aphasia Battery (WAB). The Aphasia Quotient (AQ) is a composite score that reflects the overall severity of language impairment. The AQ score ranges from a minimum of 0 to a maximum of 100. Higher scores indicate better language function (i.e., less severe impairment).
Baseline, immediately after all interventions have ended
