Title: A Double-blind, Sham-controlled, Randomized Clinical Trial on Stroke Treatment Using Transcranial Direct Current Stimulation
Brief Summary: The purpose of this study is to determine whether active stimulation of the affected hemisphere will be more effective than simulated current in treatment of stroke


Options:
A: Inclusion Criteria:

* ischemic stroke causing arm weakness within 5-15 days
* 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 more than one disabling stroke
* 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
B: Inclusion Criteria:

* Males and females subjects. Age \> 18 years.
* Diagnosis of first ischemic stroke
* Impairment of the upper limb
* Trunk control defined in the Trunk-Control Test (TCT), with a score \> 50.

Exclusion Criteria:

* anyone who does not have adequate understanding of verbal or written information in Italian sufficient to complete any test
* Impaired cognitive functioning: score less than 24 on the Mini Mental Status Examination (MMSE)
* contraindications to single-pulse transcranial magnetic stimulation (TMS)(TMS will be used to measure cortical excitability): presence of a history of epilepsy, frequent headaches or neck pain, implantable devices (ventriculoperitoneal shunts, pacemakers, intrathecal pumps, intracranial metal implants)
* Contraindications to tDCS: intracranial metal implants that can be stimulated, incorrectly positioned or over-heated by the electric current
* Neurological or psychiatric pathology
* severe cardio-pulmonary, renal, hepatic diseases
* Pregnancy
C: Inclusion Criteria:

* Ischaemic acute stroke
* Informed consent

Exclusion Criteria:

* 25 ≤ National Institute of Health Stroke Scale ≤ 32
* Rankim ≥ 5
* Mini Mental State Examination ≤ 24
* tDCS criteria: use of modulators of the Central Nervous System drugs; patients with implanted metallic or electronic devices; pacemaker; seizures; pregnancy;any other condition that might limit or interfere in the sensorimotor system CIMT criteria: inability to actively execute the movements of wrist flexion, metacarpophalangeal and interphalangeal active extension of 10º and wrist extension of 20º
D: Inclusion Criteria:

- first -ever ischemic stroke within 5-30 days a paresis of the arm/hand with NIHSS \<15 age 35-85 years

Exclusion Criteria:

Pregnancy psychiatric disease patients with history of alcohol or drug abuse or severe depression patients with a severe language disturbances, particularly of receptive nature patients with increased intracranial pressure or serious cardiac disease patients with contraindication to TMS
