Document Summary

Skillful reaching (sometimes rely on visual information if something changes, need it for feedback to correct it) Manipulative skills about hands and feet (not only about hands) fine motor manipulative skills (handwriting) How do we develop the manipulative skills in fundamental mtor theory: need to solve dof by constarints and reduce dof the core (trunk/torso) lower extremities (legs/feet, (cid:373)ultiseg(cid:373)e(cid:374)ted (cid:271)ody , upper extremities (arms/hands, still include the core. Arm (humerus/radius/ulna) cs: support (proximal unit providing support for hand, positioning of hand, force production and modulation, transport hand.

Locating: moving head/eye and body to orient toward object (critical for successful reading) Transport: slower phase of the reach used to guide the reach accuracy. Grasping: hand movement to make contact with the object.
