 Primary outcome measure will be the total time to complete functional relevant tasks of the hand, Jebsen-Tailor-Test JTT. Secondary outcomes are tapping speed with one finger; simple reaction times SRT; pinch force; and number of correct keyboard piano sequences played in 30sec with the paretic hand. To better understand the mechanisms underlying the proposed behavioral gains, we will use transcranial magnetic stimulation TMS to identify corticomotor excitability changes.
