Abstrakt

To perform an exploratory single center randomized study that will form the basis for a larger scale, more definitive randomized clinical trial to determine the optimal time after stroke for intensive motor training. The investigators will perform a prospective exploratory study of upper extremity (UE) motor training delivered at higher than usual intensity at three different time points after stroke:

- early (initiated within 30 days)

- subacute/outpatient (initiated within 2-3 months)

- chronic (initiated within 6-9 months)

The control group will not receive the therapy intervention during the 1-year study.

Outcome measures will be assessed at baseline, pre-treatment, post-treatment, 6 months and one year after stroke onset.

Compared to individuals randomized during the outpatient (2-3 months after stroke onset) or chronic (6-9 months after stroke onset) time points, participants randomized to early intensive motor training will show greater upper extremity motor improvement measured at one year post stroke.

Experimental: Acute/Early Intervention: A 20-hour dose of early intensive upper extremity motor training therapy will be initiated within 30 days post-stroke.	Behavioral: Acute/Early Using a shaping therapy protocol, participants will receive a dose of 20 hours of intensive upper extremity therapy (in addition to their current therapy) beginning within 30 days of stroke onset.
Experimental: Sub-acute/Outpatient Intervention: A 20-hour dose of sub-acute intensive upper extremity motor training therapy will be initiated within 2 to 3 months post-stroke.	Behavioral: Sub-acute/Outpatient Using a shaping therapy protocol, participants will receive a dose of 20 hours of intensive upper extremity therapy (in addition to their current therapy) beginning within 2 to 3 months post stroke.
Experimental: Chronic Intervention: A 20-hour dose of chronic intensive upper extremity motor training therapy will be initiated 6 to 9 months post-stroke	Behavioral: Chronic Using a shaping therapy protocol, participants will receive a dose of 20 hours of intensive upper extremity therapy (in addition to their current therapy) beginning within 6 to 9 months post stroke.
Placebo Comparator: Control Intervention: Usual and customary care. No additional therapy will be initiated during the 1-year study.	Behavioral: Control Usual and Customary Care only. No additional therapy will be given during the 1-year study.
