Sensory Integration is the process through which the brain organizes and interprets external stimuli such as movement, touch, smell, sight and sound. Individuals with autism often exhibit symptoms of The goal of Sensory Integration Therapy is to facilitate the development of the nervous system’s ability to process sensory input in a more typical way. Through integration the brain pulls together sensory messages and forms coherent information upon which to act. SIT uses neurosensory and neuromotor exercises to improve the brain’s ability to repair itself. When successful, it can improve attention, concentration, listening, comprehension, balance, coordination and impulse control in some children.

Sensory integration is a therapy-based intervention, which people usually do with an occupational therapist. For example, an occupational therapist might design and implement an individual program of sensory experiences for a child with autism spectrum disorder (ASD).

The idea of sensory integrative dysfunction was first proposed by A. Jean Ayres, an occupational therapist and educational psychologist, in the 1950s and 1960s. Ayres developed sensory integration therapy in the late 1970s as a treatment for children with difficulties processing sensory information.


Sensory integration therapy is used to help children learn to use all their senses together – that is, touch, smell, taste, sight and hearing. SI therapy can improve the challenging behaviour that’s caused by difficulties with processing sensory information.

Children with autism spectrum disorder (ASD) can have trouble combining sensory information. The idea of sensory integration therapy is to use physical activities and exercises to help children learn to interpret and use sensory information more effectively.
