Primitive Reflexes - Symmetrical Tonic Neck Reflex (STNR)

Symmetrical Tonic Reflex (STNR)

Symmetrical Tonic Neck Reflex (or STNR) is also known as the crawling reflex and can be identified in the two main ways a baby bends and flexes. First, when a baby's head moves down, its legs straighten and arms bend. The next one is just the opposite. As the baby's head moves up, you'll see the legs bend and the arms straighten. STNR starts to develop as early as six months of age and should be fully inhibited by 11 months.


Step 1

A woman is using the wings of the Rezzimax Tuner to scrape her arm, starting from her fingers and ending at the base of her neck.

Set the intensity of the Tuner to the highest level you're able to tolerate. We want to start on the side of the body that's weakest. Using a moderate amount of pressure, use the wing of the Tuner to scrape your entire body, starting from your toes and moving up towards your head. Once you've finished scraping the weakest side of your body, do the same thing to the other side. We want to give the weak side of your body twice as much attention. Go back and scrape it one more time. You'll want to do this for 20 minutes every day, at least three times a week.
