Systematic Review: This new 2026 systematic review and meta-analysis adds something important to the conversation about sensory integration therapy that is important right now.
Across 23 randomised controlled trials, sensory integration therapy was associated with significant improvements in motor skills, daily functioning, and individualised goals in children. The strongest effects were seen for individualised goals, especially in studies aligned with Ayres’ principles. This is a pragmatic view, recognising fidelity is always aspirational to the benefit of the children in receipt of services, but perfection in practical application is sometimes restricted in reality. So this balanced reporting of ‘studies aligned to Ayres’ principles’ is both refreshing and very welcome right now.
This study matters.
They remind us that when sensory integration theory is understood clearly, delivered purposefully, and evaluated in relation to meaningful everyday life, the focussed outcomes we see are not just about isolated skills. They are about participation.
The review also highlights something many therapists have been saying for years. Not all so called ‘sensory approaches’ are the same. Critically studies that were more closely aligned with Ayres’ theory of Sensory Integration showed the clearest gains in meaningful outcomes.
Words matter.
Fidelity matters.
Participation matters.
For families, practitioners, and service leaders, this paper strengthens the case for carefully described, evidence informed, person centred sensory integration used in practice that supports real life doing, being, and belonging.
