What is sensory integration therapy?
Sensory Integration (SI) therapy is an occupational therapy approach developed by Jean Ayres in the 1960s and 1970s. It uses structured, child-directed sensory activities, swinging, tactile play, proprioceptive exercises, to help the nervous system process sensory input more effectively. It is delivered by occupational therapists trained specifically in the Ayres Sensory Integration (ASI) framework.
How is SI therapy different from general OT?
General occupational therapy addresses a broad range of daily living skills. Sensory Integration therapy is a specialized approach within OT that specifically targets the neurological processing of sensory input. Fidelity-based ASI requires a sensory room (with swings, climbing equipment, crash pads) and specific therapist training. Not all OTs are trained in ASI, ask specifically about your OT's SI training and credentials.
What does a sensory integration therapy session look like?
An ASI session takes place in a specially equipped sensory gym. The therapist uses a variety of sensory equipment, platform swings, lycra tunnels, ball pools, weighted tools, textured surfaces, in activities that follow the child's lead. The therapist carefully grades the sensory challenge to match the child's current processing capacity, incrementally expanding their sensory tolerance and integration abilities. Sessions are typically 45–60 minutes.
Is there evidence for sensory integration therapy?
The evidence base for SI therapy is growing but mixed. Systematic reviews show benefits for sensory and motor outcomes for autistic children when fidelity to the ASI framework is maintained. A 2020 Cochrane-adjacent review found ASI produced meaningful improvements in goal attainment for autistic children. However, evidence quality varies across studies. ASI is most supported for sensory and motor outcomes; evidence for behavior and social outcomes is more limited.
How do I find a trained sensory integration therapist in Ontario?
Look for an occupational therapist registered with the College of Occupational Therapists of Ontario (COTO) who holds specific ASI training, such as certification through the USC Mrs. T.H. Chan Division of Occupational Science and Occupational Therapy (the Ayres Clinic) or similar internationally recognized programs. Children's Treatment Centres, autism-specialized OT clinics, and some hospital outpatient departments in Ontario offer ASI.
