High-dose motor therapy improves outcomes after perinatal stroke

In infants and toddlers who had a stroke before birth or as a newborn (28 days or younger), a treatment that combined restricting the use of the stronger arm with intensive task-oriented physical therapy led to improved function and skill gained on the weak side compared to standard care, according to preliminary late-breaking science presented today at the American Stroke Association's International Stroke Conference 2026.
