If your child struggles with everyday activities — getting dressed, managing a busy classroom, or tolerating certain textures and sounds — you may have heard a professional mention sensory integration therapy. But what does it actually involve, and how does it work? This article explains sensory integration therapy in plain terms, drawing on guidance from occupational therapists and trusted UK organisations, so you can make informed decisions for the children in your care.

What Is Sensory Integration?

Before exploring the therapy itself, it helps to understand the underlying process. Sensory integration is the neurological process by which the brain takes in information from all of our senses, organises it, and produces a meaningful response. This happens constantly and automatically — allowing us to sit comfortably in a chair, respond to someone calling our name, or navigate a playground without tripping.

We typically think of five senses, but occupational therapists recognise eight. In addition to sight, hearing, taste, smell and touch, there are three "hidden" senses that play a crucial role in everyday functioning:

• Vestibular — our sense of movement and balance, processed in the inner ear
• Proprioception — our awareness of where our body is in space, informed by muscles and joints
• Interoception — our awareness of internal body signals, such as hunger, thirst, or a racing heartbeat

As noted by the NHS West Suffolk Foundation Trust, these eight senses work together to help children participate in daily activities — from learning in the classroom to playing in the garden. When a child's brain struggles to process and integrate these signals effectively, it can affect their behaviour, learning, attention, and ability to take part in everyday life.

Where Does Sensory Integration Therapy Come From?

Sensory Integration (SI) theory and the therapeutic approach that stems from it were developed by Dr A. Jean Ayres — an occupational therapist and educational psychologist who began her research in the late 1960s and 1970s. Dr Ayres was interested in understanding how difficulties with sensory processing and motor planning could interfere with daily activities and learning.

Her work gave rise to what is now known as Ayres Sensory Integration® (ASI) therapy — a structured, evidence-informed intervention that forms the basis of much of the sensory integration work carried out by qualified practitioners today. Sensory Integration Education, a UK not-for-profit organisation established in 1994, describes ASI as "a neurological process that organises sensation from one's own body and from the environment, making it possible to use the body effectively within the environment."

Who Delivers Sensory Integration Therapy?

In the UK, sensory integration therapy must be delivered by a qualified allied health professional — typically an occupational therapist (OT), speech and language therapist, or physiotherapist — who has also completed specialist postgraduate training in sensory integration. This is above and beyond their core professional qualification.

As explained by Sensory Help Now (produced by Sensory Integration Education), therapists who qualify as SI Practitioners must complete a Postgraduate Certificate in Sensory Integration, as well as a set number of supervised clinical hours. Advanced Practitioners hold a Postgraduate Diploma or MSc in Sensory Integration, accredited by Sheffield Hallam University.

All occupational therapists in the UK are regulated by the Health and Care Professions Council (HCPC), and the Royal College of Occupational Therapists (RCOT) provides updated professional guidance on best practice in sensory approaches. You can find a registered occupational therapist via the RCOT website. Access through the NHS varies significantly, and many families choose to seek a private SI practitioner.

What Happens in a Session?

A course of sensory integration therapy typically begins with a thorough assessment. The therapist will observe the child, gather background history from parents and carers, and often ask the child to attempt various physical tasks. This helps build a detailed picture of the child's individual sensory processing patterns, motor skills, and functional abilities.

From there, the therapist designs an individualised plan of intervention. Sessions themselves are play-based and child-led — they may look like fun to an outside observer, but every activity is carefully chosen and structured. Common features of a session might include:

• Suspended equipment such as swings or hammocks, which target the vestibular system
• Ball pools and tactile activities to engage the touch (tactile) system
• Obstacle courses that provide proprioceptive input to joints and muscles
• Climbing, crawling and balancing activities to build body awareness and motor planning

The approach uses what practitioners call the "just-right challenge" — activities are pitched at a level that gently stretches the child's abilities without overwhelming them. The therapist follows the child's lead, observing behavioural cues and adjusting activities accordingly. Carers are often encouraged to observe or take part in sessions, and strategies to support the child at home are shared throughout.

The UK-based SenITA trial — a significant randomised controlled trial conducted across Wales and England — involved children receiving 24 face-to-face sessions of manualised ASI therapy over 26 weeks, delivered by NHS occupational therapists. Carers reported improvements in goal performance and satisfaction across the course of therapy. You can read more about the trial at NCBI Bookshelf.

Who Might Benefit?

Sensory integration therapy is most commonly used to support children who have difficulty processing or responding to sensory input in a way that affects their everyday functioning. This includes children with:

• Autism Spectrum Disorder (ASD)
• Attention Deficit Hyperactivity Disorder (ADHD)
• Developmental coordination disorder (dyspraxia)
• Sensory processing differences
• Developmental delays

Signs that a child may benefit include difficulty tolerating clothing labels or food textures, becoming overwhelmed in busy or noisy environments, appearing clumsy or uncoordinated, seeking out intense physical input (such as crashing into things), or struggling to sit still and focus. Many of these behaviours can be misread as simply "naughty" or "difficult," when they are in fact the nervous system's response to sensory overload or under-stimulation.

If you recognise any of these signs, it's worth speaking with your GP, health visitor, or your child's school SENCO, who can help you explore the right pathway for assessment and support. You can also read our blog on what a sensory diet is and how it is used in occupational therapy, which often works alongside SI therapy.

What About the Evidence?

The RCOT updated its Informed View on sensory integration and sensory-based interventions in March 2026, providing guidance to occupational therapists and service commissioners on what high-quality sensory practice looks like. The RCOT advises that a child's sensory needs must always be considered in the context of their occupational engagement — that is, how sensory differences affect their ability to learn, play, socialise, and carry out daily activities.

As with many therapies in child development, the research evidence base is still growing. The RCOT recommends that goals be clearly linked to functional outcomes and that interventions be regularly reviewed. This means that reputable SI practitioners will set clear, measurable goals with families from the outset and will monitor progress throughout.

Supporting Sensory Integration at Home and School

Sensory integration therapy does not happen only in a clinic. A key part of good SI practice is supporting children across all the environments they live and learn in — at home, at school, and in the community. Therapists will often work closely with parents, carers, and school staff to share strategies and recommend activities that can be woven into daily routines.

Schools and nurseries can play an important role. Simple adjustments — such as providing a sensory circuit at the start of the school day, offering fidget tools during carpet time, or modifying the sensory environment — can make a significant difference to a child's ability to regulate and engage with learning.

At home, sensory integration therapy equipment — such as balance boards, tactile play resources, and proprioceptive tools — can be used to complement professional support. These should be used in line with guidance from your child's therapist. Our motor and tactile play collection includes a range of resources suitable for supporting sensory development at home and in educational settings.

How to Access Sensory Integration Therapy in the UK

If you believe your child may benefit from sensory integration therapy, the first step is to speak with your GP or health visitor. They may be able to refer you to your local community paediatric occupational therapy service, though availability of specialist SI therapy through the NHS varies considerably by region.

You can also search for a privately qualified SI practitioner via Sensory Integration Education's directory at sensoryintegrationeducation.com, or find a registered occupational therapist via the Royal College of Occupational Therapists.

If your child has an Education, Health and Care Plan (EHCP) or is receiving SEN support at school, it is worth discussing sensory needs with the school SENCO, who can help ensure that sensory strategies are built into your child's support plan.

Final Thoughts

Sensory integration therapy is a specialist, play-based approach that can make a meaningful difference for children who find it hard to process and respond to the sensory world around them. Delivered by qualified practitioners and supported by strategies at home and school, it aims to help children participate more fully in the activities that matter most to them — from learning and socialising, to simply feeling comfortable in their own skin.

If you are exploring this area for the first time, we hope this guide has given you a helpful starting point. As always, working with a qualified professional is the most important step.
