Handwriting Readiness: Handwriting Readiness Controversy: when are children ready for formal handwriting instruction?
What problems arise from not mastering writing readiness skills?
Ponder: Could this be the cause of Literacy problems? Decreased test Scores?
Handwriting Readiness: Handwriting Readiness Readiness factors needed to write require integrity of a number of sensoriomotor systems
1. Letter formation
2. sufficient fine motor coordination
Six Prerequisites needed prior to handwriting instruction: Six Prerequisites needed prior to handwriting instruction Small muscle development
Eye-hand coordination
Ability to hold tools
basic strokes (| ─ о + / \ × ∆)
Letter perception
Orientation

Components of Hand Function: Components of Hand Function COGNITION
sequencing skills
psychosocial skills
Components of Hand Function: Components of Hand Function EXTERNAL FACTORS
characteristics of the object: size, shape, weight
orientation of the object: on a surface or held in space
stability of the object
POSITIONING: POSITIONING The student’s positioning will affect their fine motor and handwriting skill level
POSITIONING: POSITIONING Proper Chair Size
feet flat on floor
thighs parallel with floor
ankles, knees, hips 90°
seat not too large, student can reach back
space between knee and seat front = 2” (able to put 2 fingers in this space
does not tilt student back
POSITIONING: POSITIONING Proper Chair Position
student can sit comfortably
bend slightly forward at waist
small space between chest and desk top
arm at 30° angle from trunk
POSITIONING: POSITIONING Proper Desk Size
height of desk or table should be 2” above the height of the elbow when seated
POSITIONING: POSITIONING Position of Paper
when seated properly, student should fold hand on desk and place paper under writing hand in the Δ formed
angle paper 20-35° with top right side point higher for right-handed; 30-35 ° with top left hand point higher for left-handed
place line or tape on desk as memory aid.
POSITIONING: POSITIONING Modifications
supported use is easier than unsupported use (arms on desk vs off desk
easels or slanted top desk help child sit straighter and also allow wrist extension
Shoulder Stabilityfor position and support of the arm and hand during fine motor task: Shoulder Stability for position and support of the arm and hand during fine motor task Shoulder - provides support and mobility to the arm
Parts of the shoulder include: the shoulder blade (scapula); upper arm bone (humerus; back of the ribs (thorax); and the collar bone (clavicle).
4 joints of the shoulder
ball and socket (glenohumeral joint) which most people think of as the shoulder, gives the most movement
shoulder blade (scapula) - attached to the back, necessary to keep shoulders from hunching up next to ears
collar bone (clavicle) attached to the scapula (AC joint)
breast bone (sternum) attached to clavicle, allows shrugging and rounding of shoulders; students that slump sometimes have problems with this joint.
Shoulder Stability: Shoulder Stability Development of Shoulder stability
begins to develop as an infant props on elbows when lying on stomach
continues to develop with propping on extended arms, all fours, and then crawling
Shoulder Stability: Shoulder Stability Signs of decreased shoulder stability
student may hold arms close to body while doing as fine motor task
student’s shoulders may hunch up close to their ears
student may hold tool too tightly, increasing the tightness of the muscles, decreasing and limiting fine motor movements
Shoulder Stability: Shoulder Stability Modifications
use vertical surfaces - black or white boards, paper taped to walls or doors
inclusion of shoulder strengthening activities in class and PE - arm circles, wheelbarrow walking
Somatosensory Perception: Somatosensory Perception In order words, a Sense of Touch
Many terms are used in the literature to describe somatosensory processing. Tactile, proprioceptive, and haptic perception give a student information about the materials they are using
Different types of receptors provide fine spatial discrimination and give pain and temperature information.
According to Case-Smith (1998) decreased somatosensory registration and discrimination seem to be related to delays in manipulation skills.
Sense of Touch: Sense of Touch Tactile discrimination
the ability to determine, without using vision, where the body is touched and what is touching it
if a student has decreased tactile discrimination, the ability to get meaning from the environment is diminished
if the student can’t rely on their tactile system for information then the student needs to use more visual cues
Sense of Touch: Sense of Touch Proprioceptive and kinesthetic system
information on position and movement
monitors the direction - amount
regulation of force of movement or grasp.
Essential in monitoring fine motor tasks
gives feedback, maintains movement
decreased proprioception and kinesthesia = use of too much pressure
Sense of Touch: Sense of Touch Haptic Perception
What it is
How it is activated
When it starts
Not dependent on vision
Example = stereognosis
Muscles of the Hand: Muscles of the Hand Extrinsic Muscles
Intrinsic Muscles
Muscles of the Hand: Muscles of the Hand Thenar eminence:
Hypothenar eminence:
Deep muscles:
Release: Release The developmental sequence of release
Automatic release - the first releases are reflexive
Voluntary release - develop a voluntary release from age 7-9 months; refined in precision, speed, and dexterity through 5 years of age
Problems that can impact release
Wrist Stability: Wrist Stability Description of Wrist
The need for extension
Wrist Stability: Wrist Stability Extension -
allows optimal working of the intrinsic muscles and thumb to move into the hand and work with the fingertips
The angle of the wrist extension controls the length of the finger flexors. The finger flexors cross at the wrist on the palmar surface of the hand
40° of wrist extension allows full finger flexion, efficient muscle function (Case-Smith & Berry, 1998)
Wrist Stability: Wrist Stability Flexion –
Positioned down
Allows for power grasp, such as when you open a jar.
Wrist Stability: Wrist Stability Supination -
palm is facing up.
allows the student to look at the fingers
allows the thumb and radial fingers better ease of movement
Wrist Stability: Wrist Stability Pronation -
palm is facing down.
most important range = supination full pronation to midposition supination (Exner, 95).
Wrist Stability: Wrist Stability Modifications -
horizontal surfaces promotes the wrist in neutral or flexion
vertical surfaces put the hand in an optimal position for fine motor and writing; aids shoulder stability
Using an easel or 4” binder promotes wrist extension
Arches of the Hand: Arches of the Hand Importance to hand function
Allow hand to cup
Gives position for skilled use
Grades finger power
Allows multiple sized object manipulation
Allows for thumb movement
Arches of the Hand : Arches of the Hand Structure and development
bones, intrinsic muscles, extrinsic muscles
Stability
Intrinsic responsible for change in hand arches (Strickland, 1995)
present at birth; not functional until 2nd year of life (Case-Smith & Berry, 1998)
Three types of arches:
longitudinal,
oblique, and
transverse
Arches of the Hand: Arches of the Hand Longitudinal Arch – made of four rays from carpal bones in the hand to finger tips; allow grading finger movements
Arches of the Hand: Arches of the Hand Oblique Arch – gives power to the hand from thumb to each finger, allowing the thumb to touch each finger
Arches of the Hand : Arches of the Hand Transverse Arch – two, cup hand to form concave surface in palm
Proximal Transverse Arch – reasonably fixed; provides stability
Distal Transverse Arch – allows for mobility
Slide44: Two Sides: Skill and Power
Skill Side of Hand –
thumb, index, and middle fingers
aka - radial side
Necessary to develop fine motor control and thumb opposition
allows skilled, fast, small movements Two Sides of the Hand
Separating the Two Sides of the Hand: Separating the Two Sides of the Hand Power side = ulnar side
stability
power for grip
Separating the Two Sides of the Hand: Separating the Two Sides of the Hand Development
Begins at crawling
crawling with object on thumb side
Finger isolation seen at 40 months (Erhardt, 1982)
Importance of using both sides together
Correct scissor use assists in hand separation

Requires
tactile system
Coordination thumb and fingers
Regulation
In–Hand Manipulation: In–Hand Manipulation Terms – three major categories of in-hand manipulation described by Exner (1989)
Translation
Rotation
Shift
With Stabilization
First developed without stabilization
In–Hand Manipulation: In–Hand Manipulation Generally, 50% of children will have developed
Finger to palm 1.5 – 2.0
Palm to finger 2.0 – 2.4
Simple rotation 2.0 – 2.4
Complex rotation 2.5 – 2.9
Finger to palm, stab 3.0 – 3.4
Ulnar shift of pen 4.0 – 4.4
Radial shift of pen 4.5 – 4.9
Palm to finger, stab 5.0 – 5.4
Complex rotation, 6.0 – 6.4
with palmar stabilization

Grasp Patterns: Grasp Patterns Progression = non-holding grasps → holding grasps → manipulative grasps
Begin in utero
For Prehension or Precision
Tool grasp
Grasp Patterns: Grasp Patterns Non-holding
Nonprehensile
Hand movement without grasp
Object pushed or lifted
Grasp Patterns: Grasp Patterns Holding Grasp/Nonmanipulative:
Object held partly or entirely within the hand
Object is not moved within the hand
Two holding grasps
Hook – carry purse/lunchbox
Power – hammer/knife
Grasp Patterns: Grasp Patterns Link Grasp/Blended Grasp
power with a small object (key)
Thumb opposes index finger
No finger movement needed
Manipulative/Precision Handling Grasps: Manipulative/Precision Handling Grasps Held between fingers and thumb and allows object to be moved by fingers; Two main types
Palmar Pinch Grasp – frequently used
Pad-to-pad
3 point pinch/ 3 jaw chuck
Superior forefinger grasp
Tip Pinch/Pincer grasp
Used to pick up and manipulate small objects (pegs, pennies)
Tip of thumb meets tip of any finger; all finger joints are flexed
Pencil Grasp: Pencil Grasp Dynamic tripod and lateral tripod
Tool Grasp: Tool Grasp Scissor Grasp
Preschool Crayon Hold
Knife Hold or Diagonal Volar Grasp
Tweezers Hold
Use of Two Hands Together: Use of Two Hands Together Observe use of both hands together
Bilateral Motor Coordination requires different but complementary actions
Gross Symmetrical bilateral skills:
Stabilize objects with one hand while manipulation of object by other hand
Complementary hand use

Art Projects List
Toys List
Warm-up Activities for Printing or Cursive
Real Life: Real Life Go back and talk with your OT/PT staff; talk about the caseload and see if this information could be effective in your district
If you decide to try this method, track OT referrals, participation in the program and see if direct OT intervention is decreased after 6 months, 1 year
What This Means To Your District: What This Means To Your District OT staff don’t teach handwriting; they work on the underlining components needed to accomplish the task successfully
positioning is primary
hand development skills have a great impact
lack of these skills are leading to greater number of referrals to OT
More importantly, they may be negatively impacting tests scores and performance
Next Steps : Next Steps Talk with your Occupational Therapy staff
Enlist volunteers for a fine motor program that can be supervised by teaching staff and OT staff
Provide a training and planning to establish the program
Keep accurate records of student progress
Do a program review
