Everyday sounds, textures, lights and movement affect everyone differently, and for some people these sensory experiences can feel overwhelming or hard to register at all. Occupational therapists with sensory processing expertise help build practical strategies for home, school and the community, and this article looks at what that support can involve.
Understanding Over-Responsivity and Under-Responsivity
Sensory processing differences generally show up in two broad patterns, though many people experience a mix of both across different senses. Over-responsivity means sensory input registers more intensely than expected, so things like tags on clothing, background noise, bright lights or certain food textures can feel uncomfortable or distressing. This might look like covering ears in noisy environments, avoiding messy play, or becoming distressed by crowds. Under-responsivity is the opposite pattern, where a person may not notice or register sensory input as readily, and might seek out more intense input through movement, deep pressure, loud noise or fidgeting to feel regulated. Some people also experience difficulty registering where their body is in space (proprioception) or difficulty with balance and movement (vestibular processing). These patterns are not a matter of behaviour choice or discipline, and they can vary day to day depending on tiredness, environment and stress levels. Recognising these patterns is often the first step toward finding strategies that genuinely help, rather than approaches that inadvertently add pressure.
Sensory Integration Therapy: What It Involves
Sensory integration therapy is a structured, play-based approach some occupational therapists use, typically in a specially equipped clinic space with swings, climbing equipment, tactile materials and other tools. The aim is to give the nervous system carefully graded sensory experiences in a supportive setting, helping the person build more adaptive responses to sensory input over time. Sessions are generally individualised, following the person's interests and led by their responses rather than a fixed program, and progress is monitored and adjusted by the treating OT. It's worth noting that sensory integration therapy is one approach among several, and its suitability depends on the individual's goals, age and presentation. Families are encouraged to ask their OT how progress will be measured and how the approach connects to real-life goals, such as coping with a classroom environment or tolerating personal care routines. This is not a guaranteed-outcome intervention, and results vary between individuals, which is why ongoing professional review is a standard part of good practice.
Sensory Diets and Everyday Strategies
A "sensory diet" is a term used for a personalised schedule of sensory activities built into someone's day, designed to help maintain a more regulated, "just right" state for engaging in tasks. This isn't a food-related diet; the term refers to a planned variety of sensory input. Depending on individual needs, this might include movement breaks, use of weighted or textured items, chewy or crunchy snacks, quiet spaces to retreat to, noise-reducing headphones, or scheduled opportunities for heavy work like carrying, pushing or climbing. The key idea is proactive support rather than only reacting once distress has built up. An OT will typically work with the person, family and other supports (like teachers) to identify which activities and environmental adjustments seem to help, and when to use them across the day. Because sensory needs and preferences are highly individual, a strategy that helps one person may not suit another, so a sensory diet is generally reviewed and adjusted over time as needs change.
How an OT Assesses Sensory Needs
An occupational therapist's assessment of sensory processing usually draws on several sources of information rather than a single test. This can include structured questionnaires completed by the person, parents, carers or teachers, direct observation of the person in different environments, and clinical reasoning about how sensory patterns are affecting participation in daily activities like eating, dressing, sleeping, learning or socialising. The OT will also ask about triggers, what helps the person calm or re-engage, and what goals matter most to the person and family. This assessment process is about understanding function and building a support plan, rather than providing a medical diagnosis. Where a diagnosis is relevant to funding or other purposes, this generally sits with a medical or psychological professional, and OTs often work collaboratively within a broader care team.
Practical Strategies for Home and School
Many sensory strategies can be embedded into ordinary routines without special equipment. At home, this might mean predictable routines, advance warning before transitions, a designated quiet corner, or offering choices around clothing textures and food presentation where practical. Movement breaks before homework or sit-down tasks can help some people settle. At school, strategies might include flexible seating options, access to noise-reducing headphones during assemblies, permission to use fidget tools, or a quiet space to retreat to when overwhelmed. Communication between home, school and the treating OT helps ensure strategies are applied consistently, which tends to make them more effective. Rather than aiming for a single fixed solution, the goal is usually an evolving toolkit of strategies that the person, family and educators can draw on as needed, reviewed periodically with the OT.

Frequently Asked Questions About Sensory Processing and Sensory Integration: How Occupational Therapy Can Help
Is sensory processing disorder an official diagnosis in Australia?
Sensory processing differences are widely recognised clinically and can be part of presentations like autism or ADHD, but formal diagnostic frameworks vary and diagnosis sits with qualified medical or psychological professionals. An OT can assess sensory processing and its functional impact, and will refer on for diagnostic assessment where appropriate.
Will the NDIS fund sensory integration therapy or sensory equipment?
NDIS funding depends on whether supports are considered reasonable and necessary for an individual's plan and goals, and this is assessed on a case-by-case basis. There's no guaranteed funding amount or automatic approval, so it's best to discuss specific supports with your planner, support coordinator or treating OT.
How long does sensory integration therapy usually take to show results?
This varies considerably between individuals and depends on factors like age, goals and the nature of the sensory differences involved. Your OT should discuss realistic timeframes and how progress will be reviewed, rather than promising a fixed outcome.
Can adults benefit from sensory-based OT support, or is it only for children?
Sensory processing differences can affect people across the lifespan, and adults can benefit from assessment and strategies just as children can, including for work, study or daily living contexts. The approaches used may look different for adults but the underlying principles of understanding and supporting sensory needs still apply.
What's the difference between sensory strategies and behaviour management?
Sensory strategies aim to address the underlying sensory need driving a behaviour, such as seeking movement or avoiding certain textures, rather than only responding to the behaviour itself. Working with an OT to understand sensory triggers can complement broader behaviour support approaches used by other professionals.
