Sensory Research: The Evidence Base

Why is Sensory Research Important?

Sensory research is essential to advance our understanding of the processes involved in sensory integration and enable evidence-based decision-making around helpful environmental adaptations and therapies.


How to Understand and Navigate Research: A Guide for Parents

Identifying high-quality, reputable research that addresses your family’s immediate needs can help parents to make better-informed decisions. This guide to navigating research provides parents with easy-to-understand explanations of the different kinds of research and how to interpret that research. Although the guide is aimed at parents of autistic children, the information provided concerning sourcing and evaluating research also applies to sensory integration and sensory processing topics.


What Evidence is There to Support Sensory Integration?

There is growing evidence supporting the underpinning theory of sensory integration and the effective use of sensory integration based therapy.

Sensory Integration Recognised as Evidence-Based Practice by US Child Development Research Body

The US-based Frank Porter Graham Child Development Institute, which leads the National Clearinghouse on Autism Evidence and Practice, has published an updated systematic review of literature related to interventions for autistic individuals. The 'Evidence-Based Practices for Children, Youth, and Young Adults with Autism Spectrum Disorder' report now recognises sensory integration therapy, specifically Ayres Sensory Integration, as evidence-based practice.

Recent papers supporting evidence for the use of SI Therapy, Ayres Sensory Integration® Therapy (ASI) and Sensory Modulation Approaches include:

Occupational Therapy Using Ayres Sensory Integration®: A Randomized Controlled Trial in Brazil 

Occupational therapy using Ayres Sensory Integration® was effective in enhancing self-care, socialisation, and goal attainment for children with ASD in a Brazilian cohort.

Effectiveness of Sensory Modulation for People With Schizophrenia: A Multisite Quantitative Prospective Cohort Study

This study provides evidence to suggest that sensory modulation interventions can be complementary to standard care when utilised appropriately in clinical settings. Findings also suggest that the sensory profile of people with schizophrenia differs from that of the general population, which may have clinical implications.

Evaluating the Long-Term Effectiveness of an Intensive OT Sensory Integration (OT-SI) Program for Children With Challenges in Sensory Processing and Integration

This study aimed to explore whether children could maintain improvements after OT services ended and to understand parent perspectives of OT using a sensory integration approach. The results from this study showed that children who completed the OT-SI program at CCHMC maintained improvements 6-12 months after the intervention. Themes from parent/caregiver interviews identified strengths and perceived benefits of OT-SI programs as well as potential areas for improvement for OT-SI programs.

An Intervention for Sensory Difficulties in Children With Autism: A Randomized Trial

This study evaluated a manualised intervention for sensory difficulties for children with autism, ages 4-8 years, using a randomised trial design. Diagnosis of autism was confirmed using gold standard measures. Results showed that the children who received 30 sessions of the occupational therapy intervention scored significantly higher on Goal Attainment Scales. They also scored significantly better on measures of caregiver assistance in self-care and socialisation than the usual care control group. The study shows high rigour in its measurement of treatment fidelity and use of a manualised protocol, and provides support for the use of this intervention for children with autism.

The Effects of Occupational Therapy With Sensory Integration Emphasis on Preschool-age Children With Autism

Researchers examined the effects of an occupational therapy intervention that emphasised sensory integration on five preschool children with autism using a single-subject research design. The results support descriptions in the literature regarding the behavioural changes that children with autism can make when participating in intervention using a sensory integration approach.

Effectiveness of Sensory Integration Interventions in Children With Autism Spectrum Disorders: A Pilot Study

This pilot study aimed to establish a model for randomised controlled trial research, identify appropriate outcome measures, and address the effectiveness of sensory integration (SI) interventions in children with autism spectrum disorders (ASD). Results identified significant positive changes in Goal Attainment Scaling scores for both groups; more significant changes occurred in the SI group, and a significant decrease in autistic mannerisms occurred in the SI group.

Systematic Review of Sensory Processing in Preterm Children Reveals Abnormal Sensory Modulation, Somatosensory Processing and Sensory-Based Motor Processing

This review aimed to systematically identify assessments, incidence, and nature of sensory processing disorder in preterm-born infants and children. The authors concluded that preterm-born children exhibited elevated risk for sensory processing disorder from infancy into school age. Routine screening of sensory processing, intervention intervals and parental consultations should be considered in ameliorating sensory processing and neurocognitive development.
