Every second, a child’s brain receives information from the body and the world around it: sounds, light, touch, movement, smells, tastes and signals from inside the body. Sensory integration is how the brain organises all of this so the child can play, learn, move and connect with others. When this process does not work smoothly, children may struggle with behaviour, learning and everyday activities. Sensory integration therapy, provided by occupational therapists, helps the brain process sensory input more effectively.
At Nutrimind Child Development Centre in Tripunithura (Thripunithura), Kochi, our occupational therapists use sensory integration therapy to support children with sensory processing difficulties, autism, ADHD and developmental delays. This guide explains the basics every parent should know.
Quick answer: what is sensory integration therapy?
Sensory integration therapy is an occupational therapy approach that uses play-based, structured sensory activities (such as swinging, climbing, deep pressure and textured play) to help a child’s brain organise and respond to sensory information. It works with all 8 senses: tactile, visual, auditory, gustatory, olfactory, vestibular, proprioceptive and interoceptive. It is commonly used for children with Sensory Processing Disorder, autism, ADHD and developmental coordination difficulties.
What is sensory integration?
Dr. A. Jean Ayres, the occupational therapist who developed the theory, defined sensory integration as “the neurological process that organizes sensation from one’s own body and from the environment and makes it possible to use the body effectively within the environment” (Ayres, 1979).
In simple words, it is a person’s ability to take in many kinds of sensory input, make sense of it and use it to respond appropriately.
Sensory integration usually happens automatically. Good sensory integration helps a child:
- interact with others with more confidence,
- develop motor, play and self-care skills, and
- stay organised, calm and focused.
When sensory integration does not develop well, it can lead to developmental lags, learning problems and behavioural issues.
The 8 senses in sensory integration
Most of us learned about five senses at school. Sensory integration looks at eight senses, including three that work “behind the scenes”.
| Sense | Where the input comes from | What it tells the brain |
|---|---|---|
| 1. Tactile | Skin receptors | Touch, pressure, temperature, pain, movement of hairs on the skin |
| 2. Visual | Retina of the eye | Sight: light, colour, shape, movement |
| 3. Auditory | Inner ear | Sounds: loud, soft, high, low, near and far |
| 4. Gustatory | Chemical receptors on the tongue | Taste: sweet, sour, bitter, salty and spicy |
| 5. Olfactory | Chemical receptors in the nose | Smell, and social cues that shape our responses |
| 6. Vestibular | Inner ear | Balance, movement and position in space |
| 7. Proprioceptive | Muscles and joints | Body position, weight, pressure, stretch and movement |
| 8. Interoceptive | Receptors inside the body | Hunger, fullness, thirst, temperature, need for the toilet |
1. Tactile sense
The tactile sense takes input from skin receptors about touch, pressure, temperature, pain and the movement of hairs on the skin.
2. Visual sense
Sight is processed through the visual sense. Visual stimuli are picked up by receptors in the retina of the eye.
3. Auditory sense
Sound is processed through the auditory sense. Auditory receptors in the inner ear identify loud, soft, high, low, near and far noises in the environment.
4. Gustatory sense
Taste is processed through the gustatory sense. Gustatory receptors on the tongue pick up sweet, sour, bitter, salty and spicy flavours, and they work closely with the sense of smell.
5. Olfactory sense
Olfaction is the sense of smell. Chemical receptors in the nose detect and tell apart different odours, as well as social cues that influence our natural responses.
6. Vestibular sense
The vestibular sense gets input from the inner ear. It helps us keep our balance and understand movement and the position of our body in space.
7. Proprioceptive sense
The proprioceptive sense gets input from muscles and joints about body position, weight, pressure, stretch and movement. It helps a child know how much force to use and where their body is without looking.
8. Interoceptive sense
Interoception is a lesser-known sense that helps us understand and feel what is going on inside our body. Children who struggle with interoception may have trouble knowing when they are hungry, full, hot, cold or thirsty. Difficulty with this sense can also make self-regulation a challenge.
Types of Sensory Processing Disorder (SPD)
Sensory Processing Disorder (SPD) is a term used by occupational therapists to describe ongoing difficulty in receiving, organising and responding to sensory information. It is generally classified into three main types:
- Sensory Modulation Disorder
- Sensory-Based Motor Disorder
- Sensory Discrimination Disorder
1. Sensory Modulation Disorder (SMD)
This happens when the brain has difficulty regulating how strongly it responds to sensory information. It has three sub-types.
A. Sensory Over-Responsivity (SOR)
The brain reacts too strongly to sensory input. Everyday sounds, lights, touch or textures may feel uncomfortable or overwhelming. Examples:
- Covering ears when hearing loud sounds
- Avoiding certain clothes or food textures
- Feeling uncomfortable in bright lights
- Becoming upset with unexpected touch
B. Sensory Under-Responsivity (SUR)
The brain responds less to sensory input. The child may not easily notice or respond to what is happening around them. Examples:
- Not responding when their name is called
- Not noticing when someone touches them
- Not reacting easily to certain sounds
- Appearing less aware of their surroundings
C. Sensory Seeking (SS)
The child looks for more sensory input because they enjoy or need extra sensory experiences. Examples:
- Constantly jumping or spinning
- Touching everything around them
- Crashing into cushions or objects
- Seeking hugs or strong pressure
2. Sensory-Based Motor Disorder (SBMD)
This happens when the brain has difficulty using sensory information to plan movements and maintain posture. It has two types.
A. Dyspraxia (motor planning difficulty)
The child has difficulty planning, organising and carrying out movements, especially new or unfamiliar activities. Examples:
- Difficulty learning to ride a bicycle
- Difficulty imitating actions
- Difficulty with activities that involve several steps
- Appearing clumsy during play
B. Postural Disorder
The child has difficulty keeping the body stable while sitting, standing or moving. Examples:
- Difficulty sitting upright for a long time
- Poor balance and coordination
- Difficulty maintaining body position
- Weak core stability
3. Sensory Discrimination Disorder (SDD)
Here the brain receives sensory information but has difficulty working out exactly what it means. The child can feel, hear or see something but may struggle to identify or tell it apart correctly. Examples:
- Auditory: difficulty hearing the difference between similar sounds
- Visual: difficulty telling apart similar shapes or letters, such as “b” and “d”
- Tactile: difficulty identifying an object by touch without looking
- Proprioceptive: difficulty judging how much force to use when holding or handling objects
- Vestibular: difficulty understanding body movement and position
How sensory integration therapy helps children
In sensory integration therapy, an occupational therapist first assesses how the child responds to different kinds of sensory input. Therapy then takes place in a safe sensory room, through play the child enjoys, such as swings, climbing, ball pools, textured materials and heavy-work activities. Each session is matched to the child’s needs, giving the “just right” challenge so the brain gradually learns to process sensations better.
Over time, therapy can support:
- better attention and sitting tolerance in class,
- calmer responses to sounds, touch and busy places,
- improved balance, coordination and motor planning,
- easier daily routines such as dressing, eating and grooming, and
- more confident play and social interaction.
Parents are part of the process. Our therapists suggest simple home activities, often called a “sensory diet”, so progress continues outside the clinic. Read more about the role of parents in child therapy.
When should parents consider a sensory assessment?
Consider speaking to an occupational therapist if your child’s sensory reactions regularly get in the way of daily life. For example, if your child:
- has frequent meltdowns in noisy or crowded places,
- refuses many foods or clothes because of texture,
- seems constantly on the move, crashing or spinning,
- is often clumsy or finds new motor tasks very hard, or
- does not seem to notice pain, hunger or the need for the toilet.
Early support makes a real difference to a child’s confidence, learning and family life.

Frequently asked questions about sensory integration therapy
What is the difference between sensory integration and Sensory Processing Disorder?
Sensory integration is the brain’s normal process of organising information from the senses. Sensory Processing Disorder describes ongoing difficulty with that process, which affects a child’s behaviour, learning or daily activities.
What are the 8 senses?
The 8 senses are tactile (touch), visual (sight), auditory (hearing), gustatory (taste), olfactory (smell), vestibular (balance and movement), proprioceptive (body position) and interoceptive (internal body signals such as hunger and thirst).
Who provides sensory integration therapy?
Sensory integration therapy is provided by trained occupational therapists. They assess the child’s sensory needs and plan play-based activities to improve how the brain processes sensory input.
Is sensory integration therapy only for children with autism?
No. Many children with autism benefit from it, but it is also used for children with ADHD, developmental delays, dyspraxia, learning difficulties and sensory processing difficulties without any other diagnosis.
What does a sensory integration therapy session look like?
A session looks like structured play. A child may swing, climb, jump on a trampoline, push heavy objects or explore textures, while the therapist carefully adjusts the activity to the child’s sensory needs.
How long does sensory integration therapy take to show results?
Every child is different. Some families notice changes within a few weeks, while others need several months of regular sessions. The therapist reviews goals regularly and shares progress with parents.
