The purpose of the research study is to investigate the effect of a brain stimulation technique called Transcranial Direct Current Stimulation (TDCS) in improving swallowing functions in subjects who develop dysphagia after a unilateral hemispheric infarction.
- TDCS Device
Intervention Desc: tDCS will lead to an increase in cortical excitability ARM 1: Kind: Experimental Label: tDCS Description: tDCS will provide an increase in cortical excitability. Patients will be randomized to receive tDCS or sham stimulation.
- Sham Device
Intervention Desc: Sham will provide identical subjective sensation as tDCS ARM 1: Kind: Experimental Label: sham Description: Sham stimulation will provide identical subjective sensation as anodal tDCS.
- Allocation: Randomized
- Masking: Double Blind (Subject, Outcomes Assessor)
- Purpose: Treatment
- Endpoint: Safety/Efficacy Study
- Intervention: Parallel Assignment
