Tonic Labyrinthine Reflex (TLR)
If a child has a residual TLR it can affect muscle tone and posture. The TLR is triggered by head movement in flexion or extension (looking up or down), so when the head moves, the arms and legs also move. The vestibular system plays a key factor in this reflex. The TLR is not always obvious in a child beyond 3 1/2 years. The effects of a residual TLR can cause a mismatch between the balance mechanism and the body, causing the system to get inaccurate information. The TLR can interfere with other stages of motor development, causing interruptions in some higher-level brain functioning.
