Developmental Progression of Grasp
Finger and hand skills such as writing, cutting, opening lunch boxes, and tying shoelaces. The development of these skills relies upon the age appropriate development of physical skills (such as core trunk control and shoulder strength) providing the stable base from which the arm and hand can then move with control.
