This is one way to asses a primitive reflex called the Asymmetrical Tonic Neck Reflex (ATNR).
When I turn her head, I’m watching to see if her arms automatically follow the direction of her head movement. If they do, it may indicate that this early developmental reflex is still influencing how her brain and body communicate.
✨ This simple assessment gives me valuable information about:
• Whether an ATNR reflex may still be present
• Which side is more active or dominant
• Postural control and balance
• How the vestibular system is responding
• What foundational brain networks may need additional support
You’ll also notice at the end that when she turns her head independently, her balance becomes more challenged. That’s because active head movement requires multiple systems to work together—including the vestibular system, postural reactions, visual processing, and reflex control.
One thing that’s important: I always assess reflexes both passively (with my assistance) and actively (with the child moving on their own). Comparing the two often provides some of the most meaningful clinical information.
Sometimes the simplest tests can tell us the most about how a child’s brain is organizing movement, balance, and body awareness đź§
