What is the threshold dose of upper limb training for children with cerebral palsy to improve function? A systematic review

To improve individual goals, children need to practice goals for more than 14-25 hr, combining face-to-face therapy with home practice. To improve general upper limb function (based on evidence in the unilateral population), children need to practice for more than 30-40 hr. Interventions that set functional goals and involve actual practice of those goals lead to goal achievement at a lower dose than general upper limb motor training.
