PMID 27090878WHAT IT FOUND
Neuroscientists and occupational therapists define sensory processing differently, creating barriers to collaboration.
Neuroscientists focus on controlled lab measures of neural response, while OTs focus on daily life participation. Current evidence does not confirm that sensory treatment causes functional improvement, highlighting the need for joint research.
Key findings
01Neuroscientists and occupational therapists have divergent goals: neuroscientists prioritize precise, objective measurement of neural responses in controlled settings, while OTs prioritize ecological validity and participation in daily life activities.
02The term 'multisensory integration' is defined differently across disciplines: OTs view it as organizing sensations to support daily activities like writing or eating, whereas neuroscientists define it as the influence of one sensory system on another resulting in a behavioral or perceptual change.
03Evidence for the efficacy of sensory-based interventions in ASD is currently limited and controversial, with a lack of well-controlled studies confirming that treatment improves sensory function or higher-level abilities.

What it does not show
This is a theoretical review and commentary, not a systematic review or meta-analysis, so it does not provide pooled data or effect sizes. The paper relies on the authors' interpretation of the existing literature, which may introduce bias. It does not present new empirical evidence, so it cannot confirm or refute the efficacy of any specific treatment. The focus is primarily on the intersection of neuroscience and occupational therapy, potentially overlooking perspectives from other disciplines like speech-language pathology or physical therapy.

The easy way to misread this
Do not interpret this paper as evidence that sensory integration therapy works or that specific neural mechanisms cause daily functional difficulties. The authors explicitly state that the evidence for treatment efficacy is controversial and that links between neural and behavioral measures are complex and often weak. This is a call for better research design, not a confirmation of current clinical assumptions.
