Q

How does Equal balance between flexors and extensors affect fine motor skills

A

if you have hightone and constantly flexed, you won’t be able to reach out for forks and self feed. Need an equal balance for controlled smooth movement.

Q

How to we prepare babies for function

A

prone, works on shoulder stability to be able to function later.

shoulder stability - prepare through weight bearing

elbow mobility and control - reaching and against gravity

forearm rotation and control - grabbing things and pulling to the mouth

wrist control - weight bearing on hands.

Q

lying supine and reaching up is good for what

A

working against gravity and stabilizing shoulders.

24
Q

at 4 weeks old what kind ofmovement?

A

primitive

25
Q

at 7 weeks how is movement

A

still reflex driven but more visual attention and

26
Q

at 12 weeks

A

less reflexes, better able to play without reflexes keeping us in a certain position

27
Q

grasp and relesase have 4 guiding concepts

A

reflex activity - become integrated during weight bearing

Grasp and associated release begin

Grasp and release develop is largely with objects.

Early grasp

Early-on release is

28
Q

categories of hand use

A

Constructive Activities:
Tool Use:
Action on a Surface
In-Hand Manipulation
Handwriting

29
Q

Primitive reach

A

Asymmetry
Windmill fashion, every limb on it’s own.

Swiping: first primitive reach. Hitting something by accident. They will go into ATNR and it bring hand in field of vision

30
Q

Transitional Reach

A

Skills:
Object held with both hands (3-4 months)
Two handed reach
Object transfer (5 months)

Strategies used:
Need to develop:
Should internal stability
Elbow Mobility/control
Forearm rotation/control
Wrist control

31
Q

Mature Reach

A

Plays with 2 toys; bang together

Coordinated and complementary bimanual movement

Coordinated and asymmetrical movement (dominant/assist pattern)

32
Q

mature reach

A

cross midline

use both hands

reaching

grasp and release

coordinated and bimanual movement.

33
Q

40
Q

primitive grasp

A

Primary Grasp: Reflex
Primary Release: Reflex driven
Swiping: ATNR

41
Q

Transitional Grasp

A

Sensorimotor Strategies:
Weight bearing to prepare arm and hand

Righting reactions

Postural fixations -> Limit in hand and hand to hand manipulation

Visual regarding of hand/object

Palm used as a point of stability

42
Q

postural fixation causes what

A

limits ability to reach and grasp but I need those to get the info into hands.

43
Q

In transitional grasp phase

A

Scratching/raking

Ulnar palmar grasp

Reach and Pat

Palmar Grasp

Radial Palmar Grasp

Radial Digital Grasp

44
Q

when can they pass object hand to hand

A

6 months old

45
Q

Mature grasp

A

Sensorimotor Strategies:

Equilibrium and midline stability reactions provide stable base

Internal stability proximally
Stabilizes at wrist

Within hand manipulation allowed because of increased dissociation and use of pinch grips

46
Q

Visual Orientation: Child adjusts position of the hand in relation to the object before grasping.

A

Lateral Pinch: holding a key

Inferior Pinch – fingers straight

Superior Pinch – just tips of fingers touching.

Manipulative Prehension – using fingers to play with a toy

In hand manipulation (Translation, shift, simple rotation and complex rotation

47
Q

Release Sequence

A

Involuntary release
(birth to 4 months

Mouthing and transfers from hand (to 7 months)

“Drops” objects with full extension (first volitional release)

Release is with control with external support (9-11 months)

Refined release- no external support needed (12-15 months)

48
Q

four things that we need for in hand manipulation

A

Must move independently from each other

Need force controlling grip and force to provide the lift of an object.

Change in grip force dependent on the texture of the object

Tactile input is necessary to update grip force so it can adjust to object as it is held and manipulated in the hand.

49
Q

maturation changes in the hand

A

Grasp and release are only the beginning of action of an object - true hand skill involves manipulation.

Remember all the neurological connections- maturation, practice, repetition, learned function!

50
Q

In hand manipulation
1. Translation: finger to palm

A

Object grasped by fingertips (pads) and moved into the palm, where it is released to rest on the palm.

Emerges around 18-21 mos.

51
Q

In hand manipulation
2. Translation: palm to fingers

A

Object is moved from the palm of the hands to the fingers.
More difficult than fingers to palm.

Emerges around 24 mos.

52
Q

In hand maniupation
3. Shift

A

The object is moved in linear direction across the fingers

Involves isolated control of the thumb in opposition

Emerges between 24-36 months

53
Q
  1. SIMPLE ROTATION
A

Turning or rolling an object held with the pads of the finger—approximately 90 degree’s or less.
Fingers act as a unit with the thumb opposed.
Examples—unscrewing a small bottle cap ; picking up a small peg from a table surface; rotating a puzzle piece by turning it slightly to correctly orient it in space
Emerges in function around 36 months

54
Q

Rotation of an object around its axis 180 degrees or more.
Thumb and finger are opposed and alternate movements as the object rotates.
Fingers move independently of one another
Example: an object is rotated end over end such as using the eraser of a pencil and returning it to the writing position
Emerges around 36 months and is refined through 72 months

A
  1. Complex rotation
55
Q

How does the child become a bilateral / bimanual being?
