Brief Summary
The investigators ultimate goal is to personalize brain stimulation for stroke so outcomes of the upper limb can be maximized for each individual patient. Several groups including the investigators have recently theorized that personalizing stimulation so as to selectively stimulate iM1 in mild, and cPMd in patients with greater severity would help generalize benefits of stimulation. The investigator premise that variances in expressions of plasticity can explain how to best stratify patients for robust, personalized stimulation.

Outcome Measures
Primary Outcomes (1)
Aim 1: Change in time (seconds) to perform functional reaching
Patients will be seated with test arm resting on a table. Three buttons (labeled 1, 2, 3) will be arranged in a semi-circle at 80% of reaching distance of the paretic limb. A number (1, 2, or 3) will cue patients to reach and push the designated button as fast as possible using shoulder flexion-abduction and elbow extension while their trunk is stabilized. Three blocks of 20 trials will be tested pre- and post-rTMS.
Change in functional reaching from baseline to post rTMS, assessed for approximately 4-6 hours.
Secondary Outcomes (1)
Aim 2:Change in plasticity evoked with rTMS.
Change in neurophysiology from baseline to post rTMS assessed for approximately 4-6 hours.

Eligibility Criteria
You may qualify if:
- greater than 21 years old
- more than 6 months from first, unilateral index stroke
- unilateral paresis of the upper limb indexed as greater than or equal to 20% slowness in functional reaching compared to non-paretic limb
- UEFM less than or equal to 61 out of 66.
You may not qualify if:
- subjects who cannot perform reaching with shoulder
- severe cognitive deficit (less than or equal to 24 on Mini-Mental State examination.
- contraindication to TMS or MRI including: seizures, ongoing use of certain neuro- or psycho-active medications, implants, or pacemaker.
- currently receiving outpatient therapy.
