Sensory Integrative Therapy (Sensory Integration, SI, or SIT)
Description: An intervention in which the participant receives sensory stimulation with the goal of improving attention and cognitive functioning, while decreasing disruptive or repetitive behaviors. Examples include brushing the body, compressing the elbows and knees, swinging from a hammock suspended from a ceiling, and spinning around and around on a scooter board. Examples of sensory diet interventions include wearing a weighted vest or wristbands, putting a body sock on the participant, or massaging the child’s mouth or other body parts. Sensory Integrative Therapy is often supervised by an occupational therapist.
Research Summary: Although Sensory Integrative Therapy has been a popular intervention for individuals with autism spectrum disorders since the 1970s, reviewers have concluded, “There exist so few studies that conclusions cannot be drawn” (Dawson & Watling, p. 419).
Recommendations: An important area for future research is to evaluate Sensory Integration in studies with strong experimental designs. Professionals should present Sensory Integration as untested and encourage families who are considering this intervention to evaluate it carefully.
