Effects of tDCS in Language Recovery and Reorganization in Chronic Aphasia
In Brief
A clinical study evaluating Targeted Transcranial Direct Current Stimulation, Active Control Transcranial Direct Current Stimulation, and 2 other interventions for Stroke and Aphasia. Completed, enrolled 25 participants across 1 site.
Detailed Summary
This study will investigate the effects of mild electrical stimulation in conjunction with speech therapy for people with post-stroke aphasia to enhance language recovery.
Study Details
Timeline
Interventions
High-Definition-tDCS will be delivered via a battery-driven constant direct current stimulator (Soterix) using a 4x1 montage (1 central anodal electrode and 4 cathodal electrodes) arranged in a HD-cap. The current is turned on and increased in a ramplike fashion over approximately 30 seconds until reaching a strength of no more than 2mA, with a current density equal to 0.08mA/cm2. Stimulation will be maintained no longer than 20 minutes, and stimulation will be applied to the targeted region.

Participants are asked to generate or choose from a list phonologic information about a target picture.
Participants who have difficulty retrieving an object name are given hierarchical clues or asked questions about the objects function as a way of activating the semantic network for that object, leading to eventual retrieval of the target word.
