Title: tDCS in Chronic Stroke Recovery-pilot
Brief Summary: The hypothesis of this study is that different subgroups of stroke will respond differently to direct current stimulation.


Options:
A: Inclusion Criteria:

* Clinical diagnosis of stroke, presenting with hemiplegia
* Within 14 days of stroke onset
* Medically stable
* Able to...

  * tolerate daily therapy for a minimum of 30 minutes per session
  * sit for more than 5 seconds without support
  * understand and follow 1 stage commands

Exclusion Criteria:

* Previous stroke with residual impairments
* Other neurological diagnosis (e.g. Parkinsons Disease, Multiple Sclerosis)
* Clinically relevant pre-morbid disability levels
B: * INCLUSION CRITERIA:
* Age between 18 and 85 years.
* Ability to sit and be active for an hour on a chair (or wheelchair) without cardiac, respiratory and/or pain disturbances as assessed during the screening visit.
* Willingness to commit to participate in the long-term follow-up study (up to 3 months)
* Willingness to give written informed consent.
* Diagnosis of a first clinically apparent unilateral cortical or subcortical stroke at least 3 months prior to study entry

EXCLUSION CRITERIA:

* History of severe neurological illness (e.g. brain tumor, epilepsy or acute seizures, polyneuropathy etc.) or severe cognitive impairment (MMSE less than 23)

* History of alcohol or drug abuse
* Active depression of any severity with psychoactive medication changes in the last 2 months, active psychosis, disruptive or violent behavior, poor motivational capacity as assessed by the study physician by patient questioning
* Aphasia or language disturbances that would interfere with performing the study tasks
* Uncontrolled medical problems (e.g., active cancer or renal disease, any type of end-stage pulmonary or cardiovascular disease, diabetes, or other medical conditions, as determined by the study physician, that would interfere with participation in this study).
* Increased intracranial pressure as evaluated by clinical means (fundoscopic exam).
* Severe neglect or ataxia that would interfere in the completion of the study tasks.

* Serious cardiac conditions (history of congestive heart failure, documented serious and unstable cardiac arrhythmias, hypertrophic cardiomyopathy, severe aortic stenosis, angina or dyspnea at rest or during activities of daily living). Anyone meeting New York Heart Association criteria for Class 3 or Class 4 heart disease will be excluded
* History of serious chronic obstructive pulmonary disease or oxygen dependence

* Intracranial hemorrhage related to aneurysmal rupture or an arteriovenous malformation (hemorrhagic infarctions will not be excluded)

Inclusion and exclusion criteria will be determined by a chart review, depression screen and subject interview by study physician or study coordinator. After initial chart and subject interview, each subject's treating physician will be asked to review inclusion and exclusion criteria and provide a letter supporting inclusion in the study. All subjects who meet selection criteria must successfully complete an exercise tolerance test
