This document discusses cortical control of hand function from childhood to adulthood. Grasping an object requires the coordination of sensory, cognitive, and motor skills that develop in children. Reaching and grasping are cortical phenomena involving independent finger movement guided by sensory information and visual transformation of object characteristics into adequate hand configurations. Somatosensory feedback is essential for learning new movements, and key moments in motor development should be considered when understanding, treating, and evaluating children with disabilities.
