The asymmetrical tonic neck reflex (ATNR), also known as the "fencing reflex," is a primitive reflex present in infants. While it's crucial for early development, its persistence beyond the typical timeframe (generally disappearing around 6 months) can hinder motor skills and coordination. This article explores how to identify ATNR and provides exercises to help integrate this reflex, improving overall motor development. We'll also address common questions surrounding this reflex.
What is the Asymmetrical Tonic Neck Reflex (ATNR)?
The ATNR is an involuntary reflex where when a baby's head is turned to one side, the arm on that side extends while the opposite arm flexes. Imagine a baby lying on its back, turning its head to the right. Its right arm will straighten, while its left arm bends at the elbow. This reflex is essential for early development, helping babies to learn to reach for objects and eventually develop hand-eye coordination. However, persistence of the ATNR beyond infancy can interfere with several motor milestones.
How Do I Know if My Child Still Has the ATNR?
If your child is beyond the typical age range for the ATNR to disappear, several signs can indicate its persistence:
- Difficulty crossing the midline: Your child may struggle to reach across their body from one side to the other.
- Poor hand-eye coordination: Challenges with activities requiring hand-eye coordination like catching a ball or writing.
- One-sided preference: Your child may consistently prefer one side of their body over the other for activities.
- Awkward posture or gait: The child's posture or walking pattern may appear unusual or uncoordinated.
- Reading difficulties: ATNR persistence can sometimes be linked with challenges in reading, as it affects eye tracking and visual spatial awareness.
What Exercises Can Help Integrate the ATNR?
These exercises aim to help your child overcome the limitations imposed by a persistent ATNR. It is crucial to consult with a pediatric occupational therapist or other qualified professional for personalized guidance. They can assess your child’s specific needs and develop a tailored exercise plan. The following are general examples and may not be suitable for all children:
1. Neck Rotation Exercises:
Slowly rotate your child's head from side to side, encouraging them to reach their arms across their midline. Start with small movements and gradually increase the range of motion. Avoid forcing the movement.
2. Weight-Bearing Activities:
Activities that require your child to bear weight on their hands and knees, such as crawling or playing on all fours, can help integrate the reflex.
3. Midline Activities:
Engage your child in activities that require crossing the midline of their body, such as reaching across to grab a toy or stacking blocks.
4. "Snow Angels" and Similar Exercises:
Have your child lie on their stomach and lift their arms and legs simultaneously, making “snow angel” movements. This helps promote bilateral coordination and counteracts the asymmetrical nature of the ATNR.
What Are the Potential Consequences of an Unintegrated ATNR?
Persistent ATNR can lead to various developmental challenges, including:
- Difficulties with writing and drawing: The reflex can make it challenging to hold a pencil or crayon correctly and control fine motor movements.
- Problems with sports and physical activities: Coordination and balance issues can hinder participation in various sports.
- Reading and learning difficulties: Eye tracking and visual spatial awareness are affected, leading to challenges in reading comprehension.
- Poor posture and body awareness: The persistent reflex contributes to poor posture and lack of body awareness.
When Should I Seek Professional Help for a Persistent ATNR?
If you suspect your child has a persistent ATNR and it's affecting their development, it's crucial to consult with a healthcare professional, such as a pediatrician or occupational therapist. They can properly diagnose the condition and recommend appropriate interventions. Early intervention is key to minimizing potential long-term effects.
Can Massage Therapy Help With ATNR Integration?
While massage therapy isn't a standalone treatment, it can be a complementary approach to ATNR integration as part of a broader therapy program designed by a qualified professional. Gentle massage and stretching around the neck and shoulders might help improve muscle tone and flexibility, supporting the effectiveness of other exercises.

Always consult with a healthcare professional before starting any exercise program for your child. Early identification and intervention are vital for maximizing your child's developmental potential.
