Landaus reflex, also known as Landau's response or the parachute reflex, is a primitive reflex observed in infants. It is named after the Russian physician Lev Semenovich Landau, who first described it in 1925. This reflex is typically present from around 3 to 12 months of age and disappears as the infant develops.
When a baby with a fully developed Landaus reflex is held in a horizontal position face-down, their body will respond with an automatic extension of the head, legs, and arms. This extension creates a parachute-like posture, with the limbs outstretched and the back arched. The reflex is triggered by the sensation of being tilted forward or the sensation of falling.
The purpose of the Landaus reflex is believed to be a protective mechanism that prepares the infant for upright posture and the ability to control their body during potential falls. It is part of the infant's early motor development and helps to facilitate the development of core strength, balance, and coordination.
It's important to note that the presence or absence of the Landaus reflex at a specific age can vary from one infant to another. Some babies may exhibit the reflex earlier or later than the typical age range, and its disappearance can also vary. The development and disappearance of primitive reflexes are influenced by various factors, including the individual's neurological maturation and environmental stimulation.
As the infant grows and acquires more advanced motor skills, such as sitting, crawling, and walking, the Landaus reflex gradually integrates into more voluntary movements, and the baby gains greater control over their posture and movements. Other reflexes, such as the Moro reflex and the grasp reflex, also follow a similar pattern of integration into voluntary motor skills as the baby develops.
It's worth noting that if the Landaus reflex persists beyond the expected age range or if there are concerns about the infant's motor development, it is recommended to consult with a pediatrician or a healthcare professional for further evaluation and guidance.
