A child can hear the same sound as everyone else, feel the same texture, see the same movement and receive the same information from their environment, but their brain may process that information differently.

This is one reason some children may become overwhelmed by certain sounds, avoid particular textures, constantly seek movement, struggle with body awareness or find everyday activities more difficult than expected.

But what exactly is happening?

This is where sensory integration and sensory processing become important.

In this first part of our Sensory Integration Therapy series, we will explain what sensory integration means, why it matters in childhood and how occupational therapists use this understanding to support children’s everyday participation.

 

What Is Sensory Integration?

Sensory integration is the process through which the brain receives, organises and uses information from the different sensory systems.

Our brains receive sensory information all day.

A child may be:

• Hearing a parent’s voice
• Feeling their clothes against their skin
• Seeing toys around them
• Feeling their feet on the floor
• Moving their body
• Noticing hunger or thirst
• Smelling food
• Feeling the position of their body while climbing

The brain has to take all this information and make sense of it.

It then helps the child decide how to respond.

For example, when a child is walking across an uneven surface, the brain receives information about movement, balance, touch and body position. The child can then adjust their body to remain balanced.

This ability to take in sensory information, organise it and use it to respond is an important part of sensory integration.

What Is Sensory Processing?

You may also hear the term sensory processing used alongside sensory integration.

Sensory processing refers broadly to how the nervous system receives, organises and responds to sensory information.

A child may process sensory information in ways that affect how they respond to:

• Sounds
• Touch
• Movement
• Visual information
• Smells
• Tastes
• Body sensations

For some children, particular sensory experiences may feel too intense.

For others, the information may not seem noticeable enough, or they may actively look for more movement, touch or other sensory experiences.

These differences can affect how a child participates in everyday activities.

 

Why Does Sensory Integration Matter?

Sensory processing is happening whether a child is sitting in a classroom, playing at home, eating dinner or climbing on playground equipment.

It is connected to everyday participation.

A child uses sensory information when they:

Play

They need to see, touch, move and interact with toys and people around them.

Eat

They experience the smell, taste, texture, temperature and appearance of food.

Get Dressed

They experience different fabrics, pressure and movement against their skin.

Learn

They need to process information from their environment while listening, looking, sitting and using their hands.

Move

They need information about balance, movement, body position and force.

Complete Daily Routines

Bathing, brushing teeth, grooming and other routines all involve sensory experiences.

So when we talk about sensory integration, we are not talking about something that happens only during therapy.

Sensory processing is part of everyday life.

What Might Sensory Processing Differences Look Like?

Children can respond to sensory information in many different ways.

For example, a child might:

• Become uncomfortable with certain clothing textures
• Avoid messy play
• Cover their ears around certain sounds
• Seek frequent jumping, spinning or climbing
• Seem to miss information around them
• Have difficulty knowing where their body is in space
• Become overwhelmed in busy environments
• Have difficulty participating in certain daily routines

However, it is important not to assume that one behaviour automatically means a child has a sensory processing problem.

The same behaviour can have different reasons.

That is why a child’s overall development, environment, behaviour, strengths, challenges and daily participation need to be considered.

Is Sensory Integration Just About Sensory Activities?

This is an important question.

You may see sensory activities online involving:

• Swings
• Balls
• Play dough
• Sand
• Climbing
• Jumping
• Heavy work
• Different textures

These activities can provide sensory experiences, but not every sensory activity is sensory integration therapy.

Sensory integration therapy, particularly the Ayres Sensory Integration® approach, is a specific occupational therapy approach that involves individualised assessment and intervention.

The therapist considers the child’s sensory and motor abilities, participation, developmental needs and functional goals when planning intervention.

The purpose is not simply to give a child as much sensory input as possible.

The bigger goal is to support the child’s ability to participate meaningfully in everyday activities.

What Does Sensory Integration Therapy Look Like?

Sensory integration therapy is individualised.

Two children who appear to have similar sensory behaviours may not need exactly the same intervention.

An occupational therapist may observe how a child:

• Moves
• Plays
• Responds to sensory information
• Uses their body
• Interacts with people and objects
• Completes everyday tasks
• Responds to challenges

The therapist then uses this information to develop appropriate goals and intervention strategies.

Depending on the child’s needs, therapy may involve activities that challenge and support sensory-motor skills in a safe and purposeful way.

The activities are not chosen simply because they are “fun sensory activities.”

They should have a reason and connect to the child’s individual needs and functional goals.

What Is the Goal of Sensory Integration Therapy?

The goal is not to make every child respond to sensory information in exactly the same way.

Children have different sensory preferences and ways of experiencing the world.

Instead, therapy aims to support functional participation.

That may mean helping a child participate more effectively in:

• Play
• School activities
• Dressing
• Eating
• Grooming
• Movement
• Social activities
• Family routines
• Other meaningful daily activities

In other words, the question is not simply:

“Can we change this child’s sensory response?”

We also need to ask:

“How is this sensory experience affecting what the child is able to do?”

That shift in perspective is important.

Sensory Integration and Occupational Therapy

Occupational therapists look at how children participate in the activities that are meaningful and important in their everyday lives.

For children, these “occupations” can include playing, learning, getting dressed, eating, moving, interacting and participating in family and school routines.

Sensory processing is one part of understanding why a child may find some of these activities easier or more difficult.

A paediatric occupational therapist may therefore consider sensory processing alongside:

• Motor skills
• Fine motor skills
• Gross motor skills
• Visual-motor skills
• Attention
• Regulation
• Play skills
• Daily living skills
• Environmental factors

This gives a more complete picture of the child.

 

Sensory Integration Is Not a One-Size-Fits-All Approach

One of the most important things for parents to understand is that there is no single sensory strategy that works for every child.

A strategy that helps one child may not be appropriate for another.

For example, one child may enjoy movement activities while another child may become uncomfortable with the same type of movement.

This is why individual assessment, observation and professional guidance are important when sensory concerns are affecting a child’s everyday life.

When Should Parents Seek Professional Support?

Consider speaking with a qualified paediatric occupational therapist if sensory-related behaviours are regularly interfering with your child’s daily life.

For example, if your child is consistently struggling with:

• Dressing
• Eating
• Grooming
• Sleep routines
• School participation
• Playing
• Movement
• Attention during activities
• Tolerating everyday environments

A professional can help you understand what may be contributing to the difficulty and whether further assessment or support would be appropriate.

Sensory Integration: Looking Beyond the Behaviour

Sometimes, what adults see as “difficult behaviour” may be a child’s response to an experience that feels overwhelming, uncomfortable or difficult to process.

This does not mean every challenging behaviour is caused by sensory processing.

But understanding sensory experiences can give us another important piece of the puzzle.

Instead of only asking:

“Why is the child doing this?”

we can also ask:

“What is the child experiencing, and how might that be affecting their ability to participate?”

That question can lead to a much better understanding of the child’s needs.

What Have We Learned?

Sensory integration is about how the brain receives, organises and uses sensory information.

Sensory processing happens throughout the day and can influence how children interact with their environment and participate in everyday activities.

For some children, sensory processing differences may make certain experiences more challenging.

Understanding these differences can help parents, teachers and therapists look at the child more holistically.

And importantly, sensory integration therapy is not simply about providing sensory activities.

It is about understanding the individual child and supporting meaningful participation.
