Peds Reflexes

Reflexes for Test 1

QuestionAnswer
STNR symmetrical tonic neck reflex
nickname for positive response to STNR cat
emergence of STNR 4-6 months
integration of STNR 8-12 months
positioning to test STNR suspended prone over knees, ventroflex and dorsiflex head
STNR positive response to ventroflexion flex arms, extend legs
STNR response to dorsiflexion extend arms, flex legs
ATNR asymmetric tonic neck reflex
nickname for positive response to ATNR stimulus fencer
emergence of ATNR 0 mos
integration of ATNR 4-6 mos
positioning to test for ATNR supine, turn head to side
response to test for ATNR extension of arm and leg on face side, flexion on skull side
TLR-S tonic labrinthine reflex - supine
emergence of TLR 0 mos
integration of TLR 4 mos
positive response for TLR-S extremities extend or have increased extensor tone while supine (head at midline)
positive response for TLR-P extremities will flex or have increased flexor tone while prone (head at midline)
Moro reflex startle reflex
positioning for Moro reflex sit semi reclined and drop head 30 degrees
positive response for Moro reflex abduction, extension, external rotation of the arms; extension and abduction of the fingers
emergence of the moro reflex 0 mos
integration of the moro reflex 6 mos
positioning for flexor withdrawal reflex supine, legs extended
emergence of the flexor withdrawal reflex 0 mos
integration of the flexor withdrawal reflex 2 mos
positive response to flexor withdrawal reflex test stroke foot and leg of stroked foot will flex
range of time for rooting reflex 0-3 mos
stimulus for rooting reflex stroke cheek
positive reaction to stimulus for rooting baby turns head to stimulus
range of time for suckling reflex 0-5 mos
stimulus for suckling reflex strike lip with firm pressure
positive reaction to suckling stimulus sucks
range of time for palmar grasp reflex 0-6 mos
stimulus for palmar grasp reflex strike plam on ulnar side (finger, long block)
positive reaction to palmar grasp stimulus grasps object
range of time for plantar grasp reflex 0-4 to 9 mos
stimulus for plantar grasp reflex stroke foot
positive response to plantar grasp stimulus toes flex and curl to grasp
range of time for primary standing reflex 0-2 mos
stimulus for primary standing reflex touch feet to surface
positive response to primary standing reflex stimulus will bear weight on feet
range of time for automatic walking 0-2 mos
stimulus for automatic walking reflex touch feet to surface
positive response to stimulus for automatic walking reflex automatic steps
range of time for extensor thrust 0-2 mos
stimulus for extensor thrust supine, leg flexed, stroke flexed leg's foot
positive reaction to stimulus for extensor thrust extension of stroked foot
range of time for crossed extension 0-2 mos
stimulus for crossed extension supine, one leg flexed; then flex the other leg
positive reaction to crossed extension stimulus opposite leg will extend
alternative position for testing STNR in older children quadruped; positive response is going into a 'girl pushup' upon stimulus
range of time for parachute reactions lifetime
What is the parachute reaction? arms extend to protect head and catch fall
protective extension another name for parachute reaction
time forward protective extension (parachute reaction)emerges 6 mos
time when sideways protective extension (parachute reaction) emerges 7 mos
time when backwards protective extension (parachute reaction) emerges 10 mos
Landau reaction time period 3-4 mos to 12-24 mos
stimulus for Landau reaction prone in space "airplane" - raise head; arms and legs extend
cortical reactions serve to return body to vertical position after displacement
equilibrium reactions correct body displacement
five positions to test equilibrium 1. prone, 2. supine, 3. sitting, 4. quadruped, 5. standing
equipment to test equilibrium therapy ball, tilt board
Why text reflexes and righting reactions? to indicate a normally developing CNS or indicate delays
