NCT01132066

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Dysphagia Outcome and Severity Scale Score (DOSS)

    DOSS is a validated swallowing assessment scoring system that will rate the severity of dysphagia. It will be performed by a speech and swallow pathologist.

    5 days after study enrollment

Secondary Outcomes (1)

  • Incidence of seizure

    5 days after study enrollment

Study Arms (2)

tDCS

EXPERIMENTAL

tDCS will provide an increase in cortical excitability. Patients will be randomized to receive tDCS or sham stimulation.

Other: tDCS

sham

PLACEBO COMPARATOR

Sham stimulation will provide identical subjective sensation as anodal tDCS.

Other: Sham

Interventions
