Transcranial direct current stimulation treatment in chronic after-stroke dysphagia: A clinical case.

Background: Transcranial direct current stimulation (tDCS) is a non-invasive neuromodulation technique that has shown positive effects in a variety of motor diseases including dysphagia. However, its clinical application and underlying microstructural effects are still being researched. We tested whether tDCS applied together with swallowing training could benefit a treatment-resistent patient with dysphagia after a stroke.
