Symmetrical Tonic Neck Reflex (STNR)
The STNR is the reflex that precedes the ability to crawl. When the baby's head is up the arms automatically straighten while the knees and hips automatically flex so the baby can sit on thier heels. When the head is lowered, the arms automatically flex. lowering the chest and shoulders as the legs straighten, so the child looks as if they are ready to do a forward roll. The purpose of this reflex is to enable the child to get to their knees to begin crawling or standing. During the changing of positions in this reflex, the eyes change focus from near to far, being lowered to the floor and scanning the horizon.

More About the STNR
Emerges 6-9 months after birth and integrates 9-11 months after expected delivery..
