Primitive Reflex
Tonic Labyrinthine Reflex (TLR)
Spatial awareness, balance, posture, and muscle tone — through the vestibular system.
The tonic labyrinthine reflex emerges prenatally and typically integrates by ages 3–4 months. It enables spatial awareness regarding up/down and front/back orientations, maintaining balance, posture, and muscle tone through the vestibular system in the inner ear.
Integration is essential for achieving motor milestones including rolling, sitting, crawling, and walking. Unintegrated reflexes cause involuntary limb positioning during head movement, disrupting coordinated intentional movement.
Symptoms When Unintegrated
- •Motion sickness
- •Poor coordination and balance
- •Poor posture and low muscle tone
- •Fear of heights
- •Sports and gym avoidance
- •Fatigue when standing
- •Poor sense of time, rhythm, and sequencing
- •Convergence, divergence, and depth perception difficulties
- •Eye movement and visual perception problems
