Established care
Sensory therapies
Ayres Sensory Integration, sensory-based interventions, weighted vests, auditory integration, listening programmes
Two things are sold under one word. Manualised Ayres Sensory Integration has been tested in trials; the sensory add-ons sold around it mostly have not.
Randomised or controlled trials in children are under way or completed, but the result is not yet settled enough for routine care. Taking part in a registered trial is reasonable; paying for it as an established treatment is not.
Where it stands, condition by condition
The same therapy can be well supported for one problem and completely untested for another. This is the single most common place families are misled.
| Condition | Evidence | What that means here |
|---|---|---|
| Ayres Sensory Integration (manualised) — participation goals in autism | In clinical trials | Randomised trials exist, using fidelity measures and individualised goal outcomes. Results are promising for functional goals; evidence is not strong enough to call it established. |
| ASI for core autism features or academic skills | Early research only | A different and weaker claim than improving participation in a specific child. |
| Weighted vests and blankets for attention or behaviour | Not supported by evidence | Studied repeatedly; benefit for attention has not been demonstrated. Blankets may help some children settle at night, which is a comfort claim, not a therapy claim. |
| Auditory integration and listening programmes | Not supported by evidence | Reviewed multiple times without demonstrated benefit. |
| Brushing protocols, swings and sensory diets as stand-alone treatment | Early research only | Widely delivered, largely untested as discrete interventions. |
What it is
Ayres Sensory Integration is a specific, manualised therapy: a trained occupational therapist, specialised equipment, child-led play that provides controlled vestibular, proprioceptive and tactile input, with fidelity to a defined protocol and goals set with the family.
Sensory-based interventions are the separate menu of add-ons — weighted vests, brushing, swings, listening programmes, sensory diets — often delivered by people without that training.
Only the first has been tested as a therapy. The two are routinely spoken about as if they were the same thing, and that is where families are misled.
How it is meant to work
The proposal is that some children process sensory information atypically, that this interferes with attention, regulation and participation, and that structured sensory experience within play improves how they cope.
The underlying neuroscience is contested. Being unconvinced by the theory, however, is not the same as showing the therapy does not help a child participate — those are separate questions, and critics sometimes conflate them too.
What has actually been tested
- Trials of manualised ASI in autistic children, using fidelity measures and individualised goal attainment, have reported improvement in functional goals. The studies are modest in size, and findings on broader measures are weaker.
- The weighted vest is the clearest case. It is one of the most frequently recommended sensory tools and has been studied repeatedly without demonstrating benefit for attention or behaviour.
- Auditory integration and commercial listening programmes have likewise not held up under review.
- A fair summary: ASI may help a specific child reach specific participation goals; the accessories sold around it should not be assumed to carry that evidence with them.
What we still do not know
- Which children respond, and whether any pretreatment measure predicts it.
- Whether gains persist after therapy ends.
- How much of the effect comes from intensive, individualised, playful adult attention rather than the sensory content.
Risks and costs
- Direct harm is low; the cost is time and money that could buy therapy with stronger evidence.
- Equipment bought on advice and then unused is extremely common.
- The more serious risk is diagnostic: attributing distress to “sensory issues” when the cause is pain, constipation, sleep deprivation, anxiety or a communication failure the child cannot report.
Questions to ask before you agree
A centre that is doing good work will welcome these questions and answer them in writing.
- Is this manualised Ayres Sensory Integration delivered by a trained therapist, or sensory-based activities?
- What functional goal are we targeting, and how is it measured?
- Before we treat this as sensory, has pain, sleep, constipation and communication been checked?

Early detection and early intervention
The single highest-value thing in this whole field, and the one least often discussed in clinics selling treatment. Cerebral palsy can be identified in the first months of life, and that is when therapy does the most.
Established careGoal-directed, task-specific training
Not a brand of therapy but the principle underneath the ones that work: the child practises the actual task they are trying to learn, with enough repetition to matter.
Established careConstraint-induced therapy and bimanual training
For a child who uses one hand much more than the other, these are among the best-evidenced interventions in paediatric neurology — and both work, for different things.
Established carePhysiotherapy and strength training
Well supported when it is built around function and genuinely loaded — much weaker when it is passive stretching and generic exercise.
Established careOccupational therapy
The discipline that works on what the child actually does all day — dressing, eating, writing, playing, getting through a school morning.
Established careSpeech, language and communication
For a child who cannot speak clearly, giving them a way to communicate is among the most consequential interventions available — and the fear that it will stop them talking is unfounded.
Established careSpasticity and tone management
Medical and surgical treatment of tone, which works best when it is tied to a functional goal rather than to a number on a tone scale.
In clinical trialsTechnology-assisted rehabilitation
Useful mainly as a way of delivering more practice, not as a treatment in its own right — and that distinction decides whether it is worth the money.
In clinical trialsNamed physiotherapy approaches
Families are usually asked to choose between brands. The evidence says the brand matters far less than whether the session is active, goal-directed and repeated often enough.
Established careVision and cerebral visual impairment
The most commonly missed problem in children with brain injury. A child who cannot interpret what they see is often described as inattentive, uncooperative or more delayed than they are.
