Infant Reflexes : Position /stimulus/ Reaction

What is the stimulus for Rooting?

Stoke cheek/lip

What is the starting position for Rooting?

Supine, head mid-position

ID reflex:

Rooting

What is the reaction for Rooting?

Head turns towards stimulated side

Seeking with mouth

Why is Rooting reflex important?

Locating food source for survival

what is the position of Suck-swallow reflex?

Supine, head mid-position

What is the stimulus for Suck-Swallow reflex?

Nipple/finger inserted into infant’s mouth

Lips are tougher

What is the reaction for Suck-swallow reflex

Sucks vigorously and rhythmically

Why is Suck-swallow reflex important?

Feeding and nutrient intake

What is the Starting position for Palmar Grasp reflex?

Supine, head in mid-postion

What is the stimulus for Palmar Grasp Relfex?

Pressure to palm

What is reaction for Palmer Grasp reflex?

Finger flexion, reflexive grasp

What is palmer grasp reflex important

Tactile stimulation to palm

Preparation for voluntary grasp

Starting position of Plantar Grasp reflex?

Supine, leg extended

ID reflex

Plantar grasp

ID stimulus

Press finger/object along the metatarsal phalangeal groove of sole of foot

ID reaction

Toes curl into flexion

Why is plantar grasp important?

Tactile discrimination in feet

Preparation for standing and walking

ID reflex:

Traction reflex

Starting Position:

Supine

Stimulus:

Grasp infant’s forearms and pull to siT

Reaction

Initial head lag followed by complete

Flexion of Upper extremities

Why is Traction reflex important?

Preparation for voluntary control of grasping

ID reflex:

Moro (Startle)

Starting position:

place infant a semi-reclined position

Stimulus:

Rapid postural change: sensation of falling

Reaction

Immediate extension and abduction of arms, axgtension and abduction of fingers, and arching of back; followed by flexion and Adduction

Why is Moro(Startle) reflex impotant/

“Alarm” system triggered by sudden loss of support

Starting position of Galant reflex

Prone suspension

Stimulus of Galant relfex

Hold infant in prone; stroke along one side of spine

Reaction of Galant reflex

Lateral trunk flexion on stimulated side

Why is Galant reflex important

Facilitates trunk control and stabilzation

Preparation for future crawling and creeping

ID reflex:

TLR (prone)

Starting position

Prone

Stimulus

Placing infant in prone

Reaction

Into flexor tone

ID reflex

TLR (supine)

Starting position

Supine

Stimulus

Placing infant in supine

Reaction

Extensor tone

Why is TLR (prone and supine) important?

Preparation for voluntary muscle control needed for functional mobility

ID reflex

Neonatal neck righting

Starting position

Supine

Stimulus

Fully turn/rotate head to one side

Reaction:

Log rolling: roll entire body with the side of head

No set,meta; roll; lees mature, no trunk rotation

Why is Neonatal neck righting important/

Develop head control

Preparation for crawling initiative rolling

ID reflex

Placing

Starting position

Held verification position

Stimulus

Touch dorsum (upper surface) of foot

Reaction

Foot rise over the object

Importance of Placing reflex

Preparation for crawling, facilitated by quadruped

ID reflex

Babinski

Starting position

Supine, feet extended

Stimulus

Stoke plantar heel to toes

Reaction

Big toe extends upward

Why is Babinski reflex important

Tactile discrimination in feet

Preparation for standing and walking

ID reflex

ATNR

Starting position

Supine, head in mid-position, arms and legs extended

Stimulus

Rotate head to one side

Reaction

Extension of arm and leg on face side, flexion of arm and leg on opposite side

Importance of ATNR

Attention of head in preparation for eye-hand coordination
