Development of Hand Skills
Terms in this set (26)
Components of hand skills:
Effective use of hands depends on interaction of hand skills, postal mechanisms, cognition and visual perception
What are the mature pencil grips?
Dynamic tripod, lateral tripod, dynamic quadripod, and the lateral quadripod
This grip is characterized by holding the writing tool with the whole hand or extended fingers, pronating the forearm and using the shoulder to move the pencil
This grip is characterized by the pencil being held with flexed fingers and the forearm is pronated (thumb side down) or supinated
In this type of grip the pencil is stabilized by the distal phalanges of the thumb and index, middle and possibly ring fingers; the wrist is slightly extended yet dynamic; and the supinated forearm rests on the table
Finger -> palm translation occurs at what ages?
Palm -> finger translation and simple rotation occurs at what ages?
Shift and complex rotation occurs at what ages?
In hand manipulation with stabilization occurs at what ages?
True or false: rotation of small-medium objects is easier than rotation of larger objects?
Dynamic grasps are or are not mature grasps?
Static grasps are or are not mature grasps?
What is the standard grip for handwriting?
This involves purposeful and goal directed manipulation of a tool to interact with other objects or materials
Precursors to precision grasps:
Ulnar palmar, palmar, radial palmar, raking, radial digital, inferior pincer
Precision grasps (grasps WITH thumb oposition)
Pad-to-pad, three jaw chuck, tip pinch
Grasps without thumb opposition - power grasps
Hook grasp, basic power grasp, lateral pinch, spherical grasps, cylindrical grasps, disk grasp
Sequence for voluntary release:
Pulls object out of other hand or stabilizes with mouth
Releases to other hand with relaxing hand fully opened
Extends elbow in order to extend fingers for object release
Uses elbow flexion with release
Releasing objects into containers and stack blocks (fingers still fully extend)
Voluntarily release of small objects with graded extension
Ball throwing skills sequence:
Ability to throw ball forward and maintain balance
Aim ball toward target and project ball ~3 feet forward
Throw ball 5-7 feet in straight line toward target
Overhand throw to target 5 feet away
Overhand throw to target 12 feet away
Bilateral hand use sequence:
Fingering hands in midline
Banging objects together
One hand stabilizes while other manipulates object requires dissociation of hands
Opposing hand and arm movements
Hand preference develops and progresses until when?
Develops in preschool and progresses until ~8 years old
Snipping of scissors occurs at what age?
Cutting across 6 inches of paper occurs at what age?
Cut on 6 inch line occurs at what ages?
?Cutting a circle occurs at what age?
Cutting a square occurs at what ages?
