Card Set Information
for the principel of "reflex before cortical control" what's the early and matured responses?
: ATNR, Moro
: limbs move indep of head
asymmetrical tonic neck reflex
turn head to side, and the limbs on nose-side extend while those on occiput side flex
for the principel of "total body movement before issolted movement (dissociation)" what's the early and matured responses
: upper extremity swiping; prone kicking w both legs
: grasping skills; prone flex/ext knee
for the principel of "proximal control before distal control" what's the early and matured responses
: shoulder and hip stabilility
: elbow, wrist, hand, knee ankle stability
for the principel of "cephalic before caudal" what's the early and matured responses
: shoulder control & stability
: hip control & stability
cephalocaudal direction of body control by quarters (quarters of the first year???)
: head control
: arms & upper trunk
: lower trunk & pelvis
: mobility & control of lower legs, and upright postural control
which antigravity control comes first?
extensor before flexor (can lift head in prone before in supine)
wt bearing on flex/ext extremities - which comes first?
flexed - prone on elbow comes before prone on extended arms
which part of hands get control first?
med then lat
ulnar fingers before index and thumb
raking emerges when?
pincer grasp emerges when?
when does handedness appear?
around 2 yrs old, gets established at 3-4 yrs
- if it comes in before 1 yr, indicates motor impairment of opp arm
7 reflexes present at birth
Moro reflex - when does it appear? when does it disappear
28-32 weeks gestation
Moro/Startle reflex - what triggers it?
being startled - noise, change in light, change in body pos, falling
Moro/Startle reflex - what is it?
UEs abd, extend, supinate
3 troubles if the Moro/Startle reflex persists (past it's usual time for integration at 4-5 months)
throws infant off balance
excess extensor tone developmen
associated w CP
rooting reflex - what is it?
tactile stim to cheek makes head turn to that side and mouth opens
prepares the baby to suck
sucking reflex - begins when?
32 week gestation, fully developed by week 36
sucking reflex - integrates when?
how to trigger the sucking reflex?
stim the top of the mouth
fyi - sucking promotes flexion of body
palmer grasp reflex, begins when?
28 weeks gestation
palmer grasp reflex - what is it?
stim the palm and the baby grasps, can't volitionally release
when is palmar grasp integrated?
when vol grasp develops - by 6 months
plantar grasp reflex - appears when?
28 weeks gestation
plantar grasp reflex - what is it?
apply firm pressure to base of toes, and the toes will flex down
when does the plantar grasp reflex integrate?
when kid starts walking
babinski - normal response in babies?when does it integrate?
toe fanning & big toe dorsiflexing
normal up to 2 years, may disappear by 1 year
(it disappears when the system becomes more myelinated)
step or walk reflex - begins when? integrated when?
begins at 37 weeks gestation
integrated at months
what is the step/walk reflex?
alternating, rhythmical, coordinated steps
elicit it by supporting infant upright with feet on ground - support it and guide it forward
ATNR - appear when? integrates when?
what do you think of persisten neck reflexes at 12-24 months?
suggests limited motor control and possibly decreased indep amb
"neck righting on the body" - appears when? integrated when?
34 weeks gestation
neck righting on the body - what is it?
pt supine, head midline - turn the head to side, and entire body will turn in this direction
(sounds like it's really body righting on the head)
landau reflex - appears when? integrates when?
what's the Landau reflex?
hold an infant prone w yr hands under chest and stomach, and the head, neck, arms should extend so the kid's in a superman pose, everything raised above the stomach's horizontal
symmetrical tonic neck reflex - what is it?
flex/ext neck, legs move you away from where you're looking, arms do the opposite
: LE ext, UE flex
: LE flex, UE ext
when is the symmetrical tonic neck reflex (STNR) present?
4th - 7th month
parachute reflex - present when?
appear 6-9 months
cortical thumb - appears and disappears when?
found in normally developing infants
resolves 1.5-7 months
