Title: TDCS-enhanced Stroke Recovery and Cortical Reorganization
Brief Summary: The purpose is to determine whether application of a non-invasive battery powered device called transcranial direct current stimulation (tDCS) can improve recovery of hand weakness after stroke beyond what is achievable with rehabilitative treatment alone.


Options:
A: Inclusion Criteria:

* Diagnosis of stroke according to WHO's definition of stroke
* Living in the city of Trondheim or the municipalities of Asker or Bærum
* Included 2.5 - 4 months after stroke
* Modified Rankin Scale 0 - 4
* Living at home
* Mini Mental State Examination \> 20 or \> 16 if aphasia
* Provide informed consent

Exclusion Criteria:

* Are already included in the study
* Are included in other experimental studies
* Unstable coronary function
* Uncompensated heartfailure
* Other diseases that make it difficult to complete the intervention
B: Inclusion Criteria:

* no other neurological or psychiatric disease, who are able to perform study tasks

Exclusion Criteria:

* patients younger than 18 or older than 80 years

* Patients with bilateral motor impairment
* Patients with poor motivational capacity, history of severe alcohol or drug abuse
* Patients with severe language disturbances, particularly of receptive nature
* Patients with serious cognitive deficits (defined as equivalent to a MMS score of 23 or less)
* Patients with severe uncontrolled medical problems (e.g., seizures, progressive stroke syndromes, severe rheumatoid arthritis, active joint deformity of arthritic origin, active cancer or renal disease, end-stage pulmonary or cardiovascular disease, or a deteriorated condition due to age or others),
* Patients with unstable thyroid disease
* Patients with increased intracranial pressure
* Patients with unstable cardiac arrhythmia
* Patients with contraindication to TMS or tDCS stimulation (pacemaker, an implanted medication pump, a metal plate in the skull, or metal objects inside the eye or skull, patients who had a craniotomy, skin lesions at the site of stimulation)
* Patients who are not available for follow-up at 3 and 12 months
* Pregnancy
* Patients with contraindication to MRI will not participate in MRI
C: Inclusion Criteria:

* Acute first-ever stroke
* Korean Mini-Mental State Examination: 11\~24 at 7 days after stroke onset

Exclusion Criteria:

* Transient ischemic stroke
D: Inclusion Criteria:

All subjects must be between the ages of 18-90 and must not be pregnant.

Additional Entry criteria for Stroke subject enrollment:

1. First-time clinical ischemic or hemorrhagic cerebrovascular accident - evidenced by a radiological (or physician's) report;
2. Weakness, defined as score of less than 55 (out of 66) on arm motor Fugl-Meyer (FM) scale
3. Stroke onset \>6 months prior to study enrollment.

Exclusion Criteria:

1. Significant pre-stroke disability;
2. Major depression, as defined by Hamilton Depression (HAM-D) scale grater then or equal 17 if needed (history of depression before the stroke);
3. Any substantial decrease in alertness, language reception, or attention that might interfere with understanding instructions for motor testing;
4. Excessive pain in any joint of the paretic extremity (not applicable to severe stroke subjects);
5. Contraindications to single pulse Transcranial Magnetic Stimulation (TMS) (TMS will be used to measure cortical excitability) such as metal head implants

   * history of seizures
   * unexplained loss of consciousness
   * metal in the head
   * frequent or severe headaches or neck pain
   * implanted brain medical devices.
6. Contraindications to tDCS

   * metal in the head
   * implanted brain medical devices
7. Advanced liver, kidney, cardiac, or pulmonary disease;
8. A terminal medical diagnosis consistent with survival \< 1 year;
9. Coexistent major neurological or psychiatric disease as to decrease number of confounders;
10. A history of significant alcohol or drug abuse in the prior 6 months;
11. Use of carbamazepine and amitriptyline;
12. Subjects may not be actively enrolled in a separate intervention study targeting stroke recovery and
13. Subjects may not have already received constraint induced motor therapy and/or tDCS treatment for stroke;
14. History of epilepsy before stroke (or episodes of seizures within the last six months).
15. Subjects with global aphasia and deficits of comprehension
16. Pregnancy
