[Babkin's reflex in newborn: new reflexogenous zone]

The authors have studied the hand-mouth reflex of Babkin on 422 newborns. 413 out of 422 newborns were considered normal. We have found responses not yet published such as accentuation of inferior limb flexion, trunk flexion, upper limb adduction, contraction of the mentalis muscle, contraction of the orbicular of the lips, extension of the inferior limb, extension of the pododactiles and cry. We obtained the same responses by pressing the infraclavicular space just near the esternal bone. We compared statistically: a) responses to the stimulus on the palm of the hand and on the new reflexogenous zone; b) responses presented by term and preterm newborns; c) responses of newborns less than 12 hours of age and more than 24 hours of age.
