Intervention model description: Active repetitive transcranial magnetic stimulation administered through cap worn by patient under healthcare provider.
Primary purpose: TREATMENT

Brief summary: Transcranial magnetic stimulation for post-stroke upper-body motor deficits.

Detailed description: This study uses transcranial magnetic stimulation (magnetic pulses delivered through a specially designed cap worn on the head aimed at specific motor areas of the brain (brain areas responsible for the body's physical movements) to test whether upper-body motor function can be improved.

This is a double-blind study where half of participants will receive active transcranial stimulation and the other half of the participants will receive no transcranial magnetic stimulation; all participants will wear the cap. Participants and some members of the research team will not know who received active magnetic brain stimulation.

Eligibility criteria: Inclusion Criteria:

* Patients aged 18-80 years;
* Clinical diagnosis of chronic ischemic stroke recovering for more than 3 months with unilateral motor deficits of arm and leg, or arm alone; --

Exclusion Criteria:

* History of seizure;
* Epileptogenic activity (indicative of increased risk of seizures) on EEG;
* Any active unstable medical condition;
* Pregnancy;
* Schizophrenia, bipolar disorder, alcoholism, or substance abuse;
* Medications which in the investigator's clinical judgment significantly lower the seizure threshold;
* Presence of metal or electronic implants in the head (or any in the body that preclude MRI) , including pacemakers, defibrillators, aneurysm clips, neuro-stimulators, cochlear implants, metal in the eyes, etc.;
* Any changes in medications prescribed for the treatment of stroke impairment within six weeks prior to inclusion in the study or at any time during the study.
* Botulinum toxin use within two months prior to the screening visit or any planned use of botulinum toxin during the study
* Changes in NIHSS and motor assessment scores between Visit 1 and Visit 2 indicating that the patient's impairment is not stable. The following cutoffs, based on research establishing Clinically Important Differences, will be used for this determination:
* National Institutes of Health Stroke Scale: A change in total score of more than 2 points in either direction, or a change in the motor extremity score of more than 1 point in either direction.
* Fugl-Meyer Assessment of Sensorimotor Impairment: A change of more than 5 points in either direction on the upper-extremity motor score for the affected arm.
* Action Research Arm Test: A change of more than 5 points in either direction on the ARAT score for the affected arm.
* Any condition that precludes a high quality brain MRI scan.
