Hypothesis: Therapy-induced functional improvements are associated with increased motor control in the lesioned (stroke) hemisphere as measured by: (a) enlargement of lesioned hemisphere motor maps (robotic TMS), (b) increased functional connectivity between lesioned motor and sensory cortices (rsfMRI), (c) strengthened correlations between lesioned motor cortex NAA and clinical function (MRS), and (d) improved position sense of the affected upper extremity (KINARM robot)
