NEONATAL REFLEXS PRESENTED BY - DR KRITIKA JOSHI ASSISTANT PROFESSOR KAUMARBHRITYA Dept. HAMC & H
Slide2Neontal Reflexes The newborn babies have a large number of primitive reflexes which are brain- stem mediated automatic responses.These reflexes are useful for clinical purposes. One should observe whether the response is sluggish , normal, exaggerated and symmetric or asymmetric.
Slide31. Moro Reflex or Startle Reflex2.Glabellar Tap3.Rooting and Sucking Reflex4.Tonic neck Reflex5. Palmar Reflex6. Plantar Reflex7. Stepping Reflex
Slide41. MORO REFLEX- The baby should be held supine over the right hand and arm, the flexed head is suddenly allowed to drop by about 30 angle .A positive response consists of rapid abduction and extension of upper limbs and opening of hands followed by slower adduction and flexion.Moro response is asymmetric in brachial palsy and fracture of clavicle or humerus.
Slide5Slide62. Glabellar Tap Tapping of nasion is followed by closure of eyes in infants above 30 weeks gestation. 3.Rooting and Sucking reflex-Stimulation of angle of mouth or lips would initiate rooting and sucking in infants above 34 weeks gestation
Slide7Slide84. Tonic neck reflex-When the baby's head is turned to one side , the ipsilateral arm and leg gets extended while contralateral limbs are flexed .If a baby constantly or persistently maintains, the tonic neck posture , it is abnormal and may signify future development of cerebral palsy .
Slide9Slide105 & 6 Palmar and plantar grasp-The finger is placed on the palmar surface of fingers or plantar surface of toes of the baby to elicit grasp or flexion of toes . Most primitive reflexes' disappear b/w 3 and 4 months of age and their persistence is considered as an early sign of cerebral palsy.
Slide117. Stepping Reflex -Consists of movements of walking which are elicited when the infant is held upright and inclined forward with soles of feet touching a flat surface .
