| Sumario: | Background: Primitive reflexes (PRs) are of great importance to visual function due to their ability to interfere with visual projection (VP). VP is defined as the binocular behavior pattern, which, when measured, determines whether there is an orthophoria or identifies the point closest to it. The purpose of this study was to assess the relationship of four primitive reflexes and to determine how their inhibition modified VP. Methods: We investigated the use of two different therapies for the inhibition of four PRs, including the Moro reflex (MR), the tonic labyrinthine reflex (TLR), the asymmetric tonic neck reflex (ATNR), and the symmetric tonic neck reflex (STNR), in a group of 78 children (aged 4 to 15) with modified VP. The Van Orden star (VOS), which aids in understanding how progressive inhibition of PRs modifies VP, was the outcome measure. Results: The results showed a significant correlation between inhibition of PRs and improvement in VP (p=0.000; <0.05). The values obtained suggest that the changes obtained as a consequence of inhibiting PRs are similar regardless of the therapy used. For the total sample of 78 children, the majority experienced an increase in VOS scores of 1 to 4 points. Conclusion: The results suggest that inhibition of PRs enhances motor control and is significantly associated with the improvement of binocular coordination.
