Transcranial Direct Current Stimulation (TDCS) for Facilitating Swallowing Improvement After an Acute Unilateral Hemispheric Stroke

Completed

Phase 1/2 Results N/A

Trial Description

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.

Conditions

Interventions

  • 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.

Trial Design

  • Allocation: Randomized
  • Masking: Double Blind (Subject, Outcomes Assessor)
  • Purpose: Treatment
  • Endpoint: Safety/Efficacy Study
  • Intervention: Parallel Assignment

Outcomes
