Tonic Labyrinthine Reflex

A residual TLR is significant because it can affect muscle tone interfering with the development of head righting reflexes and equilibrium responses which provide the basis for proprioceptive and vestibular integration, coordination and the control of eye movements. Stable eye movements are essential in order to focus and maintain visual attention, required for reading, writing and aligning columns correctly in maths.

Effects may be related to the following: 

  • Balance concerns

  • Mismatch between balance and body (head to body) 

  • Muscle tone

  • Posture & gait

  • Eye movement especially involving convergence (if insufficient the eyes do not turn in easily, and as a result, extra convergence effort must be used to force the eyes to turn in. This additional effort can cause a number of symptoms such as eyestrain, headaches, blurred vision, double vision, difficulty concentrating, loss of place and concentration, and reading slowly).

  • Visual perception discrepancies especially with figure ground effect (difficulty separating the primary focus from the background)

  • Motion sickness

  • Spatial skills (to think and reason about objects in three dimensions) needed in math, sports, physics.

  • Toe walkers
