Evaluation of Babinski Reflex in Neonates

Abstract

Babinski reflex (BR) is one of the infantile reflexes. Most newborn babies are not neurologically mature and therefore show a BR. Upon stimulation of the sole, they dorsiflex the great toe smaller toe will fan out. Objective of our study was to evaluate the Babinski reflex in neonates. Study was conducted on 458 neonates, babies of either sex which were categorised as preterm 120, Term SGA 123, Term AGA 215. Their plantar response was assessed using thumb nail drag method. The response was graded as flexor, extensor, equivocal and asymmetrical. Plantar response was recorded as in preterm AGA extensor 75%, flexor 5%, equivocal 8.3% and asymmetrical 11.7%. In term SGA extensor 61.8%, flexor 9.8%, equivocal 13%, asymmetrical 15.4%. In term AGA extensor 61.9%, flexor 12.1%, equivocal 14.9%, asymmetrical 11.2%. Study showed predominant extensor response in neonates. p value was 0.11.
