How INPP and Tomatis work can support children with autism and ADHD

When a family receives a diagnosis of autism spectrum condition or ADHD for their child, it often brings a complex mixture of emotions. Relief at finally having a name for what they have been observing. Worry about what it means for the future. And, almost always, an urgent question: what can we actually do to help?

The answer to that question is never straightforward, and I want to be honest about that from the outset. No single approach is right for every child, and neurodevelopmental therapy is no exception. What I can offer is an explanation of how the INPP method and Tomatis sound therapy work, and why, for some children with autism or ADHD, they may provide a form of support that complements everything else already in place.

Neither approach changes a diagnosis. That is an important thing to say clearly. A child who comes to Think Thrive with an autism or ADHD profile will leave with that same profile. What may change, for some children, is how heavily that profile weighs on them day to day. The nervous system foundations they are building from may become a little more stable, and when that happens, life can feel meaningfully different even when the diagnosis itself has not moved.

What is actually happening in the nervous system

Both INPP work and Tomatis therapy are grounded in the same basic principle: that many of the difficulties we see in children with complex neurodevelopmental profiles are, at least in part, a reflection of nervous system foundations that are still maturing. The presenting profile is real and valid. The question neurodevelopmental assessment asks is whether there is something underneath it that is making everything harder.

In the INPP model, the focus is primarily on primitive reflexes. These are automatic movement responses that develop before birth and are essential in early infancy. As the brain matures, these reflexes are normally inhibited and replaced by more sophisticated voluntary movement patterns. When that inhibition is incomplete, the primitive reflex continues to operate. It pulls on the nervous system in ways the child cannot control and often cannot even feel, and the effects ripple outward into posture, sensory processing, emotional regulation, and attention.

Tomatis therapy approaches the nervous system through sound. The Tomatis method is built around the understanding that the auditory system is one of the earliest and most fundamental systems in the brain, deeply connected to the vestibular system, to attention regulation, and to the social engagement pathways. When the listening system is not functioning efficiently, the effects are not confined to what a child can or cannot hear. They extend to how the child processes the world around them and how much energy it costs to do so.

Autism and sensory experience

Sensory differences are recognised as a core feature of autism spectrum condition. Many autistic children experience the sensory world with an intensity that is genuinely overwhelming, and the strategies available to them for managing that overwhelm often come at a significant cost to their energy, their behaviour, and their capacity to engage with learning and relationships.

Retained primitive reflexes may play a role in this. The Moro reflex, which is the primitive startle response, is frequently retained to a significant degree in children with heightened sensory sensitivity. When the Moro is still active, the nervous system remains primed for threat. Unexpected sounds, sudden changes in light, unexpected touch: these can trigger a genuine stress response rather than a simple sensory registration. The child is not being dramatic or difficult. Their nervous system is doing exactly what it was designed to do in early infancy, in a context where that response is no longer serving them well.

INPP movement work may, over time, support the inhibition of this reflex. Families sometimes describe noticing that their child has become somewhat calmer in sensory environments, or that transitions between activities are less distressing. These changes do not happen overnight, and they do not happen for every child. But for some, reducing the activity of the Moro reflex seems to lower the background level of nervous system arousal in a way that creates a little more room for other kinds of progress.

Tomatis therapy may offer something complementary, particularly for autistic children who have significant auditory sensitivities or difficulties with auditory processing. The Tomatis Listening Test can reveal whether the listening system is filtering sound efficiently, whether certain frequencies are causing disproportionate stress, or whether the right and left ear are working together in the way that supports both language processing and social communication. The sound therapy itself, delivered through the Maestro headset, works gently and gradually to retrain the auditory system and may, for some children, help to reduce the degree to which sound is experienced as overwhelming.

It is also worth noting that the vestibular and proprioceptive difficulties that many autistic children experience often have a reflex component. The Tonic Labyrinthine Reflex (TLR), when retained, can affect muscle tone, spatial awareness, and the ability to read the body's position in space. For a child who is a persistent sensory seeker, or who struggles to feel settled and grounded in their body, retained reflexes affecting the proprioceptive and vestibular systems are worth assessing.

ADHD and the challenge of regulation

ADHD is often understood primarily as a difficulty with attention, but many practitioners now see it as a broader regulatory challenge. The child who cannot stay in their seat, who acts before thinking, who is exhausted by the effort of managing a school day: these are presentations of a nervous system that is working very hard, in ways that are not always visible.

The Moro reflex is again frequently relevant here. When this reflex is retained, the nervous system operates in a state of heightened readiness that makes sustained, focused attention genuinely difficult. It is not a choice. It is not something that strategies alone can fully override, because the reflex operates at a level below conscious control. The child with a strongly retained Moro may experience their world as inherently unpredictable and slightly threatening, and the impulsivity and distractibility we associate with ADHD can be, in part, the nervous system's response to that state.

Research from INPP and other neurodevelopmental practitioners has identified retained primitive reflexes, particularly the Moro, the Asymmetrical Tonic Neck Reflex (ATNR), and the Symmetrical Tonic Neck Reflex (STNR), in high proportions of children with ADHD profiles. The ATNR, when retained, can make it difficult for a child to use both sides of the body together smoothly and may affect the ability to sit at a desk, write, or hold a comfortable reading position without undue muscular tension. The STNR may contribute to the difficulties many children with ADHD have with transitioning between postures and maintaining the physical organisation required for focused desk work.

When a daily INPP movement programme is followed consistently, some children show changes in their regulatory capacity over time. Parents and teachers occasionally describe a shift: the child seems to find it slightly less effortful to manage their impulses, or is able to sustain attention for a little longer before becoming dysregulated. Again, this is not universal, it is not rapid, and it is not a substitute for any other support the child is receiving. But for some families, it becomes a meaningful piece of the puzzle.

The role of the listening system in attention

Auditory processing is closely connected to attention, and this relationship is relevant for many children with ADHD. The Tomatis model proposes that the listening system and the vestibular system share deep neurological roots, and that when the auditory system is not functioning efficiently, one of the consequences can be difficulty with sustained attention and the regulation of cortical arousal.

For children who have significant background noise sensitivity, or who seem to tune out in noisy or unpredictable acoustic environments, a Tomatis Listening Test can reveal patterns in how the auditory system is responding. Some children with ADHD profiles show particular difficulties with right-ear dominance, which in the Tomatis model is associated with the efficient processing of language and the maintenance of focused listening. Tomatis sound therapy may, over time, support the development of more efficient auditory processing and, for some children, this may translate into slightly improved capacity for sustained attention in noisy environments.

I want to be careful here not to overstate the case. Auditory processing is one factor among many, and Tomatis therapy is not a treatment for ADHD. What it may offer, for some children, is a reduction in the auditory processing load they are carrying, which in turn may free up a little more cognitive capacity for everything else.

What both approaches share

INPP work and Tomatis therapy are different in their methods, but they share something important: both start from the understanding that many of the difficulties children with complex profiles experience are not simply psychological or behavioural. They have a neurological substrate, and that substrate is, to some degree, malleable.

Neither approach positions the child as someone who needs to be fixed. Both work with the nervous system's own capacity for development and change. The INPP movement programme does not impose new skills on a child; it revisits the developmental sequence the nervous system originally needed to move through, and offers it the opportunity to complete that process. Tomatis therapy does not override the auditory system; it gently stimulates and encourages it, working with the brain's plasticity rather than against it.

What families can realistically expect

The children who seem to benefit most from INPP and Tomatis work are those whose presenting difficulties include a significant sensory or regulatory component, and for whom existing strategies are helping but have reached something of a ceiling. If a child is already receiving good support and making steady progress, neurodevelopmental work is unlikely to be necessary. If a child is working hard, the people around them are working hard, and progress still feels slow or fragile, a neurodevelopmental assessment may offer a different angle.

The process takes time. INPP programmes typically run for twelve months or more, with regular review appointments at Think Thrive. Tomatis programmes follow a structured format with rest periods built in, and some children complete more than one block of therapy. Results vary significantly between children, and I never offer a guarantee of any particular outcome. What I can offer is a thorough assessment, an honest conversation about what the findings suggest, and a programme that is designed around your individual child rather than around a diagnostic category.

For families with autistic or ADHD children who are exhausted by the daily effort of helping their child navigate a world that does not always accommodate their needs, the idea of yet another appointment or another approach may feel like too much. I understand that entirely. There is no urgency to take the next step, and there is no single right time. But if and when you are ready to explore whether the nervous system foundations might be part of the picture, I am here for that conversation. If you're currently waiting for a Right to Choose assessment, I've written more about what reflex integration can offer in the meantime here.

A note on language and respect

I want to be clear that nothing in this article is intended to suggest that autism or ADHD is a problem to be solved. Many autistic and ADHD adults describe their neurology as an integral part of who they are, and I have enormous respect for that perspective. The question I am asking is not how to make a child less autistic or less ADHD. It is whether there is anything happening at the level of the nervous system foundations that is adding unnecessary difficulty to a child's already complex experience. Reducing that difficulty, where it is possible to do so, is offered in the spirit of making life a little more comfortable, not of changing who a child fundamentally is.
