Q

Primitive Reflexes

  • what are they
  • general integration time period
  • developmental concern if…
A

Present in newborn; response to stimulus that occurs w/o conscious thought (involuntary movement)

Generally integrated by 6 mo, NO longer than 12 mo

Developmental concern if…

  • arent present in the newborn OR
  • persist > 12 mo

Q

Affects of persistence of primitive reflexes (5)

A
  1. poor motor control
  2. delay in acquisition of motor milestones
  3. difficulty feeding
  4. difficulty w/ reaching and grasping
  5. poor eye-hand coordination

Q

ATNR

  • onset
  • integration
  • stimulus & response
A

asymmetrical tonic neck reflex

onset = birth
integration = 4-6 mo

Stimulus - turn head to one side
response - facial arm abducts and extends, occipital arm flexes and abducts
(fencing posture)

Q

STNR

  • onset
  • integration
  • stimulus & response
A

not primitive reflex

onset - 4-6 mo
integration - 8-12 mo

stimulus - flex or ext of head (in quadruped position)
response - head flexion then arms flex, hips extend; if head extension, then arms extend and hips flex
- head and arms have symmetrical movements, hips do opposite of head
