Understanding the Tonic Labyrinthine Reflex (TLR)
Research shows that the tonic labyrinthine reflex (TLR) can remain active up to 3.5 years, making it one of the longest-lasting primitive reflexes. This extended duration is likely due to its significant connection to posture. Unlike other reflexes that may only be present in utero or during early infancy, the TLR’s influence on postural development means it persists longer, aiding in the transition to more advanced postural reflexes.

Parents frequently report challenges in understanding the impact of the TLR on their child’s development. The reflex’s role in posture means that its retention can affect a child’s ability to maintain proper body alignment and balance. This is why it’s crucial for parents and therapists to recognize the signs of a retained TLR, as it can influence the child’s overall motor skills and coordination.
