Reflexes 0-12 Months Flashcards
Principle
REFLEX BEFORE CORTICAL CONTROL
earliest response
matured response
earliest response:
- ATNR
- MORO
matured response:
1. moves limbs, independent of head
Principle
TOTAL BODY MOVEMENT BEFORE ISOLATED MOVEMENT (DISSOCIATION)
earliest response
matured response
earliest: random
UE swiping
prone kicking both legs (random)
matured response: isolated
grasp
prone flexing/extending knee
Principle
PROXIMAL CONTROL BEFORE DISTAL CONTROL
earliest response
matured response
earliest:
- shoulder and hip stability
matured:
- elbow-wrist-hand-knee-ankle
Principle
CEPHALIC BEFORE CAUDAL CONTROL
earliest response
matured response
earliest response:
-shoulders control and stability
matured:
- hip control and stability
Cephalocaudal Direction First Quarter
head control in all positions
Cephalocaudal Direction Second Quarter
arms and upper trunk control (shoulder girdle)
Cephalocaudal Direction Third Quarter
lower trunk and pelvic control (hips)
Cephalocaudal Direction Fourth Quarter
mobility and control of the lower legs and upright postural control (standing)
Cephalocaudal Direction After Fourth Quarter
antigravity control
Principle
MEDIAL CONTROL BEFORE LATERAL CONTROL
earliest response
matured response
earliest:
3 ULNAR fingers dominate first grasp
matured:
thumb and index finger dominate grasp
Principle
EXTENSOR ANTIGRAVITY CONTROL BEFORE FLEXOR ANTIGRAVITY CONTROL
earliest response
matured response
earliest:
lift head in prone at 4 months , antigravity extensor
matured:
lift head in supine at 5 months, antigravity flexor
Principle
WEIGHT BEARING ON FLEXED EXTREMITIES BEFORE EXTENDED EXTREMITIES
earliest response
matured response
earliest:
prone on elbow
matured:
prone on extended arms
Principle
GROSS MOTOR DEVELOPMENT BEFORE FINE MOTOR DEVELOPMENT
earliest response
matured response
earliest:
jump
matured:
handwrite
Grasp Patterns
RAKING
emerges at 6 MONTHS
thumbs against curled index finger
Grasp Patterns
PINCER GRASP
emerges 8-12 MONTHS
pad of thumb and pad of index finger
note: WHICH IS IT??
pad to pad is more refined than tip to tip
pad to pad is nails together?
tip to tip is the palmar aspect of fingers together?
Developing hand preference before 12 months:
developing hand before 12 months indicates motor impairment in the opposite extremity
When does hand preference start?
NOT begin to develop until age 2 years
establish somewhere between 3 and 4
should see swatting, reaching, grabbing with both hands in infants
What reflexes are present at birth?
- Moro
- Suck
- Root
- Palmar
- Plantar
- ATNR
- Babinski
What reflexes are not present at birth but emerge during infancy?
- STNR
- Landau
- Parachute
