Primitive Reflexes: Stimulus & Response
Question | Answer |
---|---|
Stimulus for Rooting reflex? | stroke corner of mouth, lower and upper lip |
Stimulus for plantar grasp reflex? | apply pressure with thumb on ball of infant's foot |
Stimulus for moro reflex? | rapidly drop infants head backwards |
Stimulus for Galant? | hold infant in prone suspension, gently scratch or tap alongside spine with finger from shoulder to butt |
Stimulus for asymetric tonic neck? | Fully rotate infants head and hold for 5 sec |
Stimulus for plantar grasp? | place examiners finger in infants palm |
Stimulus for crossed extension? | supine, one leg flexed other ext, then flex extended leg |
Stimulus for flexor withdrawl? | supine position, one leg extended stimulate sole of foot |
Stimulus automatic walking? | in the standing position, hold the infant under the arms and incline forward |
Stimulus for positive supporting? | hold under arms in vertical position, balance on soles of feet, then maintain standing position |
Stimulus for negative supporting? | hold under arms in vertical position, balance on soles of feet, then hold in space |
Stimulus for tonic labyrinth? | Supine: place child in prone position, Prone: place child in supine position |
Stimulus for placing? | vertical position, brush dorsum of hand & foot against edge of table |
Stimulus for Landua? | supporting the thorax, hold the child in prone position in space |
Stimulus for neck righting on body? | place infant in supine and fully turn head to one side |
Stimulus for body righting on body? | place infant in supine, flex one hip and knee toward the chest and hold briefly |
Stimulus for symmetrical tonic neck? | place infant in crawling postion and extend head |
Stimulus for protective extension down? | with both hands hold the infant around the trunk. Lift in space. Turn upside down then move quickly towards the floor |
Stimulus for protective extension forward? | in the sitting position the child is pushed forwards toward a supporting surface |
Stimulus for protective extension side? | child is placed in sitting position and is pushed sideways on one shoulder with sufficient force to make him lose his balance. |
Stimulus for protective extension backward? | child is placed in sitting position and pushed backwards |
Response for rooting? | mvmt of tongue, mouth and or head to stimulus |
Response for plantar grasp? | toe flexion |
Response for moro? | 1st phase: arm ext and abd, hand opening, 2nd phase: arm flexion and add |
Response for galant? | lateral trunk flexion & wrinkling of skin on stimulated side |
Response for ATNR? | ext of extremities on face side; flexion of extremities on skull side |
Response for palmar grasp? | finger flexion; relflexive grasp |
Response for Crossed extension? | ext of the flexed, opposite leg |
Response for flexor withdrawl? | flexion of leg(knee & hip), dorsiflexion of foot, ext of toes |
Response for automatic walking? | automatic walking steps, which at this stage are rythmical and with heel strike |
Response for positive supporting? | increase of extensor tone in legs |
Response for negative supporting? | increase of flexor tone in legs |
Response for tonic labyrinth? | Supine: flexor tone dominates, Prone: extensor tone dominates |
Response for placing? | flexion & placement of extremity on table |
Response for landau? | extension head, trunk, and legs |
Response for neck righting on body? | log rolling of the entire body to maintain aligment with the head |
Response for body righting on body? | segmental rolling of the upper trunk to maintain aligment |
Response for symetrical tonic neck? | flexion of hips and knees |
Response for protective extension down? | extension of arms |
Response for protective extension forward? | arms project forward with extension of the elbows, wrists, and fingers. |
Response for protective extension side? | Positive reaction is abduction of the opposite arm with extension of the elbow, wrist, and fingers |
Response for protective extension back? | full reaction is backward extension of both arms. Frequently an element of trunk rotation occurs, then the reaction is seen in only one arm. |
