Full guideOccupational therapy

Occupational therapy is the discipline that assesses and treats sensory processing differences. An OT identifies which sensory systems a child over-responds to, under-responds to, or actively seeks, then builds a plan around specific daily-life goals — tolerating a haircut, sitting through a lesson, eating a wider range of foods. Sessions are play-based and often look like climbing, swinging, and messy play, which is deliberate: the activity is the assessment and the intervention at once. Ayres Sensory Integration, delivered by an OT with specific additional training, is the approach with the strongest evidence.⁠1 Sensory processing disorder isn't a standalone diagnosis in the DSM-5 or ICD-11, so what you get is a sensory profile and a plan rather than a diagnostic code.

Key takeaways

  • Occupational therapy is the discipline that assesses and treats sensory processing differences.
  • An OT identifies which systems a child over-responds to, under-responds to, or actively seeks, then builds a plan around specific daily-life goals such as tolerating a haircut or sitting through a lesson.
  • A session usually happens in a large room with suspended equipment: swings, a climbing frame, crash mats, a ball pit, textured materials.
  • It looks like play, and that is the point. The therapist is watching how a child organizes movement and what they seek and avoid while the child climbs, swings, or digs in a bin of rice.
  • In Ayres Sensory Integration specifically, the child's own choices drive the session while the therapist shapes the challenge. A session where the therapist directs every activity is not ASI.
  • Parents are often involved, particularly with younger children, and increasingly so as the plan moves toward home strategies.

Sensory processing differences involve difficulty taking in, organizing, and responding to information from the eight sensory systems. → What sensory processing differences are

What does an OT work on for sensory issues?

Which systems are affected and how · daily activities the difficulty is blocking — dressing, eating, school, sleep, play · environmental adjustments at home and school · building tolerance gradually where that's the goal · handwriting and fine motor where postural or proprioceptive difficulty is contributing · self-regulation strategies the child can eventually use themselves

How does an OT assess sensory processing?

Developmental history · standardized caregiver and teacher questionnaires — commonly the Sensory Profile 2 and the Sensory Processing Measure · structured clinical observation, often the most informative part · ruling out hearing and vision · consideration of autism, ADHD, and language disorders, which co-occur frequently → How sensory processing is assessed

What does a sensory OT session look like?

Usually a large room with suspended equipment — swings, a climbing frame, crash mats, a ball pit, textured materials.

It looks like play, and that's the point. The therapist is watching how your child organizes movement, how they respond to input, what they seek, and what they avoid — while the child is climbing, swinging, or digging in a bin of rice.

The child leads more than parents expect. In Ayres Sensory Integration specifically, the child's own choices drive the session while the therapist shapes the challenge. A session where the therapist directs every activity isn't ASI.

Parents are often involved, particularly with younger children, and increasingly so as the plan moves toward home strategies.

Typically 45–60 minutes, weekly or more.

What should sensory OT goals look like?

Tolerates having her hair brushed for two minutes · Sits at the dinner table for the length of a family meal · Wears school shoes without distress · Stays in assembly for ten minutes

Improves sensory processing · Increases sensory integration · Improves regulation

If the goals are written the second way, ask for them in daily-life terms.

Does OT for sensory processing disorder work?

Ayres Sensory Integration has moderate-quality evidence for autistic children when delivered with fidelity and adequate intensity.⁠1 Individual sensory-based techniques — weighted vests in particular — have repeatedly been found to have little or no effect.⁠2 Environmental modification has performed more consistently in research than sensory input applied to a child. → The evidence in full

How to get OT for sensory processing disorder

Under 3, early intervention, free evaluation, parent self-referral⁠3 · 3+, school evaluation, request in writing · privately · insurance often tied to an associated diagnosis, since SPD isn't a diagnostic code — ask providers how they bill

Frequently Asked Questions

Does OT help sensory processing differences?
It's the discipline that assesses and treats them. Ayres Sensory Integration has moderate evidence for autistic children; individual sensory techniques generally have weaker support.
Why does the session just look like play?
Because that's how it works — the therapist is assessing and shaping while the child moves. Child-led play is a defining feature of ASI.
Do we need a diagnosis first?
No. SPD isn't a standalone DSM-5 or ICD-11 diagnosis. An OT assessment produces a sensory profile and a plan.
How long before we see a difference?
Progress is uneven and plateaus are normal. Agree a review point at the start.
Should we buy a weighted vest?
Research has found little or no effect on the outcomes claimed. Discuss with the OT before spending.
Is this the same as sensory integration therapy?
Not necessarily. → Is SI therapy the same as OT?
