Brief Summary:
The purpose of this study is to determine whether a non-painful, non-invasive, brain-stimulation technique called transcranial direct current stimulation (tDCS) combined with traditional physical-occupational therapy (OT) will improve motor function in patients with chronic stroke. The aim is to determine the effect of applying real (anodal and/or cathodal) - in a dual configuration - vs sham (pretend) tDCS to the motor brain regions on both hemispheres - in a dual configuration - to improve motor function in chronic stroke patients. Our research in normal subjects has shown that motor skills can be enhanced if tDCS is applied to the brain's motor region during motor learning. The effects after a single session of tDCS can last for up to 30 minutes, effects of multiple sessions (one session per day) can last for weeks. Furthermore, single sessions of tDCS applied to the motor regions in stroke patients have shown that improvements in motor functions can be seen and that effects may last for at least 30 minutes. Patients enrolled in this trial will be randomized to receive either real tDCS or sham tDCS in combination with PT-OT once a day for 5 days. Assessments will be done about 3 days and 7 days after the end of the experimental treatment by investigators who are blinded to the intervention. Patients are also blinded as to whether they are receiving real or sham tDCS. We hypothesize that real tDCS applied to the motor regions in combination with PT-OT results in a subsequent improvement in motor function of the recovering hand over sham tDCS in combination with PT-OT.

Arm Intervention/treatment
Active Comparator: Real-tDCS + PT-OT
Each subject will receive up to 5 days of traditional physical-occupational therapy for at least 1 hour per day in the stroke recovery laboratory in combination with real transcranial direct current stimulation (tDCS) over the motor region for up to 30 min.
Device: Real Transcranial Direct Current Stimulation
A direct current runs between two electrode positions and affects the excitability of the underlying brain tissue
Other Names:
  • Non-invasive brain stimulation
  • Brain stimulation
  • Enhancing stroke recovery

Sham Comparator: Sham-tDCS + PT-OT
Each subject will receive up to 5 days of traditional physical-occupational therapy for at least 1 hour per day in the stroke recovery laboratory in combination with sham (pretend) tDCS for up to 30 min. over the motor region.
Device: Sham Transcranial Direct Current Stimulation
A sham current runs between two electrode positions and might affect the underlying brain tissue.
Other Names:
  • Non-invasive brain stimulation
  • Brain stimulation
  • Enhancing stroke recovery




Primary Outcome Measures :
  1. Fugl-Meyer Assessment of Upper Extremity Motor Impairment [ Time Frame: Baseline Assessment; 3 days after 5 treatment days; 7 days after 5 treatment days ]
    This scale goes from 0 to 66 (max). Higher values are considered to be a better outcome.


Secondary Outcome Measures :
  1. Wolf-Motor-Function-Test [ Time Frame: Baseline Assessment; 3 days after 5 treatment days; 7 days after 5 treatment days ]
    The Wolf-Motor-Function-Test (time) is the average time in seconds taken to perform each of 15 functional tasks ranging in difficulty from putting one's forearm on a table to stacking checkers. Participants are given 120 seconds to perform a task and if they fail, they are scored 120 for that task," or similar as accurate. The average time in seconds is then log10 transformed.
