developmental reflexes Flashcards
Rooting onset age Integration age stimulus response relevance
28 weeks gestation
3 months
stroke the corner of mouth upper lip or lower lip
movement of tongue mouth or head towards the stimulus
to search for and locate food
suck-swallow onset age integration age stimulus response relevance
28 weeks gestation 2-5 months place examiners index finger inside infants mouth with head in mid-position strong rhythmical sucking allows ingestion of nourishment
Traction onset age integration age stimulus response relevance
28 weeks gestation 2-5 months grasp infants forearm and pull to sit complete flexion of upper extremity enhance momentary reflexive grasp
Moro onset age integration age stimulus response relevance
28 weeks gestation
4-6 months
rapidly drop infants head backwards
first phase-arm extension, abduction, and hand opening. second phase- arm flexion and adduction
facilitates ability to depart from dominant flexor posture: protective response
plantar grasp onset age integration age stimulus response relevance
28 weeks gestation 9 months apply pressure with thumb and infants ball of foot toe flexion increases tactile input to sole of foot
Galant onset age integration age stimulus response relevance
32 weeks gestation
2 months
hold infant in prone suspension, gently tap or scratch alongside the spine with finger, from shoulder to buttocks
lateral trunk flexion and wrinkling of the skin on the stimulated side
facilitates lateral trunk movements necessary for trunk stabilization
Asymmetric tonic neck onset age integration age stimulus response relevance
37 weeks gestation
4-6 months
fully rotate infants head and hold for five seconds
extension of extremities on the face side flexion of extremities on the skull side
promotes visual hand regard
Tonic labyrinthine supine onset age integration age stimulus response relevance
> 37 weeks gestation 6 months Place infant in supine Increased extensor tone Facilitates total body extensor tone
Tonic labyrinthine prone onset age integration age stimulus response relevance
>37 weeks gestation 6 months place infant in prone increased flexor tone facilitates total body flexor tone
Landau onset age integration age stimulus response relevance
3-4 months
12-24 months
hold infant in horizontal prone suspension
complete extension of head trunk and extremities
breaks up flexor dominance facilitates prone extension
symmetric tonic neck onset age integration age stimulus response relevance
4-6 months
8-12 months
place infant in the crawling position and extend the head
flexion of the hips and knees
breaks up total extensor posture; facilitates static quadruped position
Body righting onset age integration age stimulus response relevance
4-6 months
5 years
place infant in supine, flex one hip and knee toward the chest and hold briefly
segmental rolling of upper trunk to maintain alignment
facilitates trunk and spinal roatation
