The Asymmetrical Tonic Neck Reflex and Learning Difficulties
Does your child struggle with handwriting?
An often overlooked reason exists. Children that have difficulties with handwriting frequently have a retained Asymmetrical Tonic Neck Reflex (ATNR).
The ATNR is a primitive reflex that babies exhibit. It is part of the development of muscle tone, consistent one-side movements with their body, and even proper hand-eye coordination. This reflex should have been inhibited by the time a child reaches around eight months. However, when it is retained, it manifests as handwriting and learning issues such as dyslexia.
Indicators your child could have a retained Asymmetrical Tonic Neck Reflex
Normally, when a child turns their head to look at a page, the active ATNR will automatically cause the arm to extend and the fingers to open. However if a child has a retained ATNR, using a pen or pencil will require more effort for the student, and they may compensate by using excessive pressure.
Further indicators your child may have ATNR:
Difficulty keeping to the left hand margin when writing
Handwriting that trails off to a slant towards the right hand side of the page
Difficulty with planning and may run out of room towards the right hand edge of the paper
The ATNR and learning difficulties
The ATNR and subsequent handwriting issues also have a bigger impact on learning for the child. They will significantly divert their energy into heavily focusing on the physical process of writing. This distracts them from what they are actually writing about.
Using a pen or pencil will require a huge amount of effort, leading to a very tight pencil grip and tension in the body. An overly tight grip can cause cramping and fatigue to set in rapidly, especially in the arm and hand. The frequent “shaking out” of a cramped hand is often an indicator of an active ATNR.
There may also be a big difference between their expression of ideas in written form versus their ability to express themselves orally.
A child with ATNR will experience eye tracking difficulties when reading. This means their eyes do not move smoothly from one side of the page to the other and frequently jump. This can result in losing their place, loss of accuracy and loss of comprehension.
They may also experience an issue called mixed laterality. This is when a child uses their left foot and right hand, or they may use left and right hands interchangeably for the same task. The effect of mixed laterality can be the failure to send information to the most efficient centre of the brain for that skill.
All of this requires intense concentration that occurs at the expense of cognitive processing. Their handwriting will suffer in terms of quality and quantity.
Neurodevelopmental therapy and the Asymmetrical Tonic Neck Reflex
At The Key Clinic, we help children to develop and mature their handwriting. Anna Trundle is one of our Neurodevelopment and Auditory Supervisor and Occupational Therapist.
Anna is a HCPC Registered Occupational Therapist with 30 years’ experience. She has a specialism in Paediatrics and Neurological Rehabilitation. Anna is also a National Handwriting Association Tutor and trained in Auditory Therapy.
Anna oversees our NeuroMature Therapy practice which helps children mature their handwriting skills, as well as overcome labels such as dyslexia.
ATNR and Dyslexia Support
Crucially, 90% of children that are diagnosed with dyslexia have a retained Asymmetrical Tonic Neck Reflex. As mentioned above, the ATNR affects the eyes’ ability to track smoothly across a line of writing, causing the eyes to jump at the midline. This means that words seem to move, with readers frequently skipping over lines and words.
Dyslexic symptoms can be effectively eased through a series of neuro-developmental movements, which give the nervous system a second chance to develop. NeuroMature Therapy uses simple, precise exercises to inhibit primitive reflexes, overcoming blockages and creating new neural pathways in the brain by maturing the nervous system.
These need to be carried out for up to 20-25 minutes a day over a few weeks/months, until any remaining primitive reflexes have fully inhibited and the system becomes fully matured.
This neurodevelopmental therapy can lead to significantly improved ability to learn and the ability to fulfil their true potential.
“We brought our eldest son to The Key Clinic at the start of his GCSE year, as he had recently flunked some really important exams. He had previously been diagnosed with Dyslexia and suffered from great anxiety and constant tummy aches/indigestion. After an in-depth assessment, he was prescribed exercises and some BrightBeatz therapy. On his return to boarding school, he achieved an instant 20% increase in his exam results across the board.”- The Phelps family
