Peds Primitive Refle
Pediatric Primitive Reflex
Question | Answer |
---|---|
ROOTING | 28 weeks/3 months Stroke cheek at corner of mouth Head turns towards stimulus Absent in depressed babies |
MORO | 28 weeks/5-6 months Allow head fall back 20-30 degrees in supported sitting Abd/ ext of shoulders, extension of elbows, wrist and fingers Challenges with sitting balance |
PALMAR GRASP | 28 weeks/4-5 months Pressure to palm. Finger flex voluntary grasp patterns |
PLANTAR GRASP | 28 weeks/9 months Pressure to foot Flex/curling of toes. Can limit & delay gait pattern |
ASYMMETRICAL TONIC NECK REFLEX (atnr) (Archer) | Birth-2 months/4-6 months Turn head to one side,Arm & leg on Difficult rolling, no middling, sciolosis, never totally obligatory in full term infant |
SYMMETRICAL TONIC NECK REFLEX (stnr) | 4-6 months/8-12 months Suspended prone position w/flex or ext of head Head flex: arms flex, leg ext Head ext: arm ext, leg flex Limits reciprocal creeping, walking Integration coincides with crawling |
TONIC LABYRINTHINE REFLEX | Birth/6 months Observe child in prone & supine Prone: flex posture dominates Supine: ext posture Diff. w/moro coord, planning & crossing midline, head control against gravity |
PRIMARY STANDING REFLEX | 32 weeks/1-2 months Support infant upright & allow feet to make firm contact Co-contract of flex & ext allow WB Hypotonia, muscle weakness, prerequisite for stepping reflex |
STEPPING REFLEX | 38 weeks/2 months Supported stand position Reciprocal flex/ext of legs Standing balance, walking,& weight shifting |
GALANT REFLEX | 30-32 weeks/2 months Positioned in prone, stroke lateral to spine from shoulder to crest, lateral flexion towards side of stimulus Affect sitting balance, lead to scoliosis |
LANDAU REFLEX | 3-4 months/12-24 months Prone suspension with trunk support Head, upper truck, and hip/legs extended Poor response with hypotonia, breaks overall flexor tone for development of head/ trunk control against gravity |
reflexes assist movement before | cortical volitional control |
generalized before | localized movement (whole arm/leg moves before individual joints) |
gross before | fine motor |
proximal before | distal (trunk before arms) |
cephalad before | caudal (head before legs) |
primitive reflexes | originate in brainstem, 'protection & survival" (breathing) |
Involuntary muscle reaction to certain types of stimulation | primitive reflexes |
persistence of primitive reflexes after typical integration age can be a sign of | damage to the CNS or brain |
asymmetry with reflexes could indicate injury to | one side of the brain |
