Finger isolation is an important stage in the development of grasp. It is the ability to move certain fingers apart from the rest of the hand/fingers. When children begin using their hands, all fingers move together at the same time. As they grow and develop, they gain the ability to move individual fingers. It helps with being able to fasten and unfasten buttons, hold and control a pencil for drawing and writing, cut with scissors, type on a keyboard, play a musical instrument, tie shoelaces, and many other daily living skills.
