Transcript of Asymmetric Tonic Neck Reflex

The Asymmetical Tonic Neck Reflex (ATNR)
This reflex is found in newborn babies and normally remains until around 6 months

It emerges in utero at around 18 weeks after conception and can be seen within the first 3 months of life

The purpose of the ATNR is to provide stimulation for developing muscle tone and the vestibular system prior to birth

This assists with the birthing process so that the baby uses a "corkscrew" movement through the birth passage

This reflex serves as a precuror to hand eye-coordination
To review:
A retained ATNR can have a significant impact on a child's development
- Baby will find it difficult for hands, feet, and eyes to cross the midline
- Prevents cross pattern movements like rolling over and crawling
- Writing is difficult because of the involuntary movement
- Reading is difficult because the individual cannot track the words
The following exercises illustrate movements which replicate the early reflex movements and build the neural pathways that will enable the child to overcome the retained reflex
