What this trial studies

This clinical trial investigates the effects of transcranial direct current stimulation (tDCS) combined with oral feeding on patients suffering from dysphagia following a stroke. Participants are randomly assigned to either an experimental group receiving tDCS or a placebo group, both of which undergo routine rehabilitation therapy and swallowing training. The trial lasts for 15 days, during which the effectiveness of tDCS in enhancing swallowing abilities is evaluated. The study aims to determine if this innovative approach can lead to better recovery outcomes for stroke patients with swallowing difficulties.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 who have experienced a first-time ischemic stroke and have confirmed swallowing disorders requiring enteral nutrition support.

Not a fit: Patients with severe cognitive impairments, other neurological disorders, or contraindications for tDCS may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve swallowing function and quality of life for stroke patients with dysphagia.

How similar studies have performed: Previous studies have shown promising results with transcranial direct current stimulation in various neurological rehabilitation contexts, suggesting potential for success in this novel application.
