Landau reflex

Landau reflex or Landau reaction refers to position of the infant when held horizontally in the air in the prone position. It emerges 3 months after birth and lasts until up to 12 months to 24 months of age.. A normal response of infants when held in a horizontal prone position is to maintain a convex arc with the head raised and the legs slightly flexed. The reflex is displayed at about 3 months of age. It is poor in those with floppy infant syndrome and exaggerated in hypertonic and opisthotonic infants .
