Motor Development 1 & 2 Flashcards
When is the onset and integration of primitive reflexes?
Some reflexes are present as early as _________ weeks gestation.
28 weeks
(About 6.4 months)
Reflexes in a typically developing child (should / should not) be obligatory
Should NOT
What is meant by “reflexes in a typically developing child should not be obligatory” ?
The infant should NOT do the reflex every time the stimulus is given.
True or false
The response depends on the state of the infant and the nervous system
True
Duration of Rooting
Birth to 3 months
Duration of spontaneous stepping
Birth to 2 months
Duration of suck/swallow
Birth to 2/5 months
Duration of Moro or Startle
Birth to 5/6 months
Log rolling with head/body movement
- neonatal NOB
- neonatal BOB
When is it present ?
When does it integrate ?
Present at or before birth
Integrates by 4-5 months when segmental rolling begins
Tonic labyrinthine reflex TLR
When is it present?
When is it integrated ?
Present at or before birth
Integrates at 6 months
Traction / Crossed extension / Flexor withdrawal / Proprioceptive Placing LE & UE
When are they present ?
When do they integrate ?
Present before birth
Integrates around 2 months
Plantar grasp duration
Birth to 9 months
Palmar grasp duration
Birth to 4/6 months
Galant duration
32 weeks to 2 months
Positive supporting (neonatal) duration
35 weeks to 2 months
ATNR duration
Birth to 4/6 months
STNR duration
4/6 months to 8/12 months
What are the automatic reactions + their BOS?
(BOS: base of support)
Righting reactions: Well within BOS
Tilting reactions : Close to edge of BOS
Equilibrium reactions: Close to edge of BOS
Protective reactions : Beyond BOS
Which automatic reaction is this?
- Securing the head in space
- Must develop in all planes
Righting reactions
Which automatic reaction is this?
- Securing the body in space when being on a MOVABLE surface (moderate perturbation to surface)
Tilting reactions
Which automatic reaction is this?
Securing the body in space when being on a STABLE surface (moderate perturbation to the body)
Equilibrium reactions
Which automatic reaction is this?
Regaining balance when the center of mass has been pushed beyond the borders of the BOS .
Protective reactions
What is the purpose of righting reactions?
When is the onset and integration?
Purpose:
- to get into and maintain upright posture for locomotion
- righting of the head and body to the horizon or adjust parts of the body to the vertebral axis
Onset: birth - PERSISTS
Labyrinthine Righting
Optical Righting
Body on Head
( all are righting reactions)
Onset and integration ?
Birth - PERSISTS
Landau onset and integration
Onset: 3-4 months
Integrates: 12-24 months
I don’t know . Just read
Ok
Onset and integration of the rolling reactions (NOB and BOB)
Onset: 4-6 months
Integrates: 5 years
Duration of positive supporting UE and LE
UE: 3/6 months and PERSISTS
LE: 6/9 months and PERSISTS
Segmental rolling onset ?
6 months
This is an example of ?
Tilting reactions
This is an example of?
Protective reactions
This is an example of?
Equilibrium reactions
Onset of equilibrium/tilting reactions in different positions .
- prone?
- sitting/supine?
- stance ?
Prone: 6 months
Sitting/supine : 7-8 months
Stance : 12-21 months
(Quadruped: 9-12 months ; i dont know what this means)
Onset of protective extension UE in different directions.
- forward ?
- sideways ?
- backward ?
Forward: 6-7 months
Sideways: 7 months
Backward: 9 - 10 months
Onset of protective extension LE in different directions.
- downward?
- shifting ?
Downward: 4 months
Shifting: 15 to 18 months
What principle does the following belong to?
Earliest control : ATNR ( limbs move in response to head position)
Control with maturation : Child volitionally moves limbs independent of head position
Reflex control before cortical control
What principle does the following belong to?
Earliest control : neonate moves upper extremities in wide sweeps and at random
Control with maturation : Child gains control of individual joints to stabilize the shoulder for precise, visually directed reach and grasp
Total response before localized response
What principle does the following belong to?
Earliest control : child develops shoulder and hip stability
Control with maturation : Elbow then wrist, and knee, then ankle, stability develop.
Proximal control before distal control
What principle does the following belong to?
Earliest control : shoulders develop control and stability
Control with maturation : hips develop control and stability
Cephalic control before caudal control
What principle does the following belong to?
Earliest control : three ulnar fingers dominate first grasp
Control with maturation : thumb and index finger dominate pincer grasp, forefinger dominance develops
Medial control before lateral control
What principle does the following belong to?
Earliest control : child has motor control of mouth at birth
Control with maturation : child develops ability to fix eyes and focus
Cervical control before rostral control
