Asymmetrical Tonic Neck Reflex

The ATNR reflex is activated when a baby turns their head to one side, the arm and leg on the jaw side automatically straighten and the limbs on the opposite side flex. The ATNR reflex is thought to have an important role to play in not only the birthing process but also early hand eye coordination and distance perception. If the ATNR reflex remains active it can significantly impact on a Childs academic performance and ability to function well in school.

Implications for a retained ATNR Reflex:

Poor handwriting
Immature pencil grip
Uses excessive pressure on pencil when writing
Rotates page by 90 degrees when writing

to compensate for reflex

Poor expression of ideas onto paper
Difficulty crossing the midline
Mixed Laterality
