Q

Moro reflex- functional/ global implications if not integrated:

A

Functional implications:
1. Motion sickness
2. poor balance/coordination
3. delayed equilibrium & righting responses
4. auditory hypersensitivity/poor auditory discrimination
5. difficulty w/ transitions
6. hypersensitivity may be seen in only one sense
Global manifestations:
Dislike change, Allergies, lowered immunity, ear infection, parents walk on eggshells, need to control, poor stamina, low self-esteem, difficulty making decisions, “glued” to mom, sedentary

Q

What does the infant automatically do during the birthing process

A

Push, turn and wriggle movements which are generated by infant reflexes.
These reflexes are progressively integrated following natural birth

Q

During the 1st year of life, what position do baby’s love to be in

A

-Lie on tummies and backs
-Move freely
-Be held, moving with adult
They can develop sensory skills relating to touch, balance and proprioception, as well as an emotional attachment

Q

What is a disadvantage of “Baby containers”

A

alters hip development.

Reflexes in the first year are not fully achieved and problems emerge. Babies are inactive in a fixed position

Q

What is one example of a postural reflex

A

Head-righting reflex

20
Q

Landau Reflex

A 
Coming in for Landau! 
Onset= 4 months
Integration= 12 months; 
Test: Suspend infant horizontally in prone ;
Response: ext head, neck, and trunk
21
Q

Landau Reflex helps develop?

A

posture, sitting and walking, inhibit TLR

22
Q

What happens if Landau is not integrated?

A

poor muscle tone, chronic neck/back pn, tension and hyperext of legs with stiffness of lower body, affects development of balance, inability to flex leg correctly, vertical eye tracking, limit field of vision, poor at sports, stiff and awkward movement of lower half, difficulty jumping and hopping

23
Q

STNR Reflex

A

Onset: 6 months
Integration: 11 months
Test 1: child is sitting on knees, tip forward
Test 1 response: Neck and arms flex up to protect face, legs separate and extend
Test 2: Place in sitting
Test 2 response: neck and arms extend, LE flex to create a slowed fall

24
Q

STNR helps develop?

A

allows to defy gravity and assume quadruped; dissociate UE and LE; integrates when they begin crawling and rocking back and fourth in quadruped

25
Q

What happens if STNR is not integrated?

A

W sitting (inhibits STNR); poor posture; hands in pockets; bunny hop instead of crawl; difficulty sitting still; falls out of chair; clumsy; poor balance; behavior problems; poor eye hand coordination; difficulty copying; difficulty sitting to do fine motor activity

26
Q

Define Reflex

A

An involuntary motor response to a sensory stimulus. They thought or planning.

27
Q

Where do reflexes originate?

A

In the brainstem

28
Q

What is the general age , when most reflexes should be integrated?

A

Usually by age 3, however postural reflexes evolve and stay with us much longer.

29
Q

What are 2 lifespan reflexes?

A
  1. Knee-jerk

2. Flexor withdrawal

30
Q

“Infant” reflexes do not persist past _______?

A

The first year

31
Q

ATNR “Fencing Pose” onset & integration

A

birth

6 months

32
Q

ATNR Testing procedure

A

child on back, gently turn head to one side

33
Q

ATNR response

A

UE flexion on opposite side of head turn and UE extension on side head is turned toward

34
Q

How ATNR helps development

A
  • Helps develop muscle tone
  • Provides vestibular stimulation
  • Develops balance
  • Decreases chances of breech birth
  • Initiates eye hand activities
  • Helps initiate rolling
35
Q

What happens when ATNR not integrated

A

Delayed eye-hand skills

  • Poor midline development
  • Difficulty crossing midline with hands and eyes
  • Difficulty with auditory processing
  • Poor organization
  • When reaching, one arm extends, other retracts
  • One leg left behind during crawling
  • Turning body while drawing/writing
  • Not spontaneously using non-dominant hand to assist
36
Q

Spinal Galant onset & integration

A

32 weeks gestation

3 months

37
Q

Spinal Galant Testing Procedure

A

Stroke down the back from below the shoulder to the base of the lumbar region at a distance of ½ inch from the spine, first on one side, then on the other. Repeat the procedure up to 3 times (repetition beyond this can fail to elicit the reaction
even though the reflex is present).

38
Q

Spinal Galant Response

A

Infant will laterally flex toward stimulated side.

39
Q

How spinal galant helps development

A

-Thought to take an active part in birthing process by stimulating lumbar region causing rotational movement of hips.

40
Q

What happens if spinal galant is underdeveloped?

A
  • Contributes to hyper-tonicity
  • Strong ATNR and STNR
  • Impeded cross patterns for crawling and creeping
41
Q

What happens if spinal galant is not integrated?

A
  • Fidgeting
  • Bed Wetting
  • Poor concentration and short term memory
  • Hip rotation to one side when walking
  • Child may only wear sweatpants (worn low) to avoid stimulation of lumbar region.
42
Q

TLR onset & integration

A

utero

36 months

43
Q

TLR testing procedure

A

Place child on back, and lift up into sitting position.

Place child on tummy.

44
Q

TLR responses

A

sitting up–> flexor tone dominates.

tummy–> extensor tone will dominate

45
Q

How TLR helps development

A
  • A response to gravity: Movement of head above the spine: extension. Movement of the head below the spine: flexion.
  • If Moro reflex isn’t integrated, TLR probably won’t be either.
46
Q

What happens if TLR is not integrated?

A

Flexor TLR:

  • Slouched posture
  • Low muscle tone
  • Dislike of physical activity
  • Stuck in flexion

Extensor TLR:

  • Toe walking
  • High muscle tone
  • Dislike of physical activity
  • Stuck in extension
  • Poor organizational skills
  • Motion sickness
