Addison LR, Piazza CC, Patel MR, Bachmeyer MH, Rivas KM, Milnes SM, Oddo J. A comparison of sensory integrative and behavioral therapies as treatment for pediatric feeding disorders. Journal of Applied Behavior Analysis. 2012; 45(3): 455-71.
This study about children with feeding issues concludes that behavioral and SI therapy used together can build the variety and amount of food the child will eat, while minimizing inappropriate behavior. Suggested behavioral therapy includes working around a child’s efforts to avoid eating (example: leaving a spoon on lips until food goes into child’s mouth) and periodically offering positive reinforcement.

Kimball JG. Using the sensory integration and praxis tests to measure change: A pilot study. American Journal of Occupational Therapy. 1990; 44(7): 603–608.
In this study, boys age 6 to 8 were pretested and post tested with Sensory Integration and Praxis Tests (SIPT), before and after 6 months of occupational therapy. Most boys showed significant SI improvements. Author suggests that SIPT is useful for documenting client improvements based on SI therapy.

Authors determined there is sufficient evidence, based on review of science literature published from 1964 to 2005, to support Dr. A. Jean Ayres’ SI theory. Results reinforce neuroplasticity, which promotes exploration of how the brain can change throughout life.

Linderman TM, Stewart KB. Sensory integrative-based occupational therapy and functional outcomes in young children with pervasive developmental disorders: A single-subject study. American Journal of Occupational Therapy. 1999; 53(2): 207–213.
In this study, two boys age 3 with pervasive developmental disorders (PDD) which involves inability to socialize, communicate and use imagination, displayed significant post therapy improvements. These findings support SI based occupational therapy to help children with PDD.

May-Benson TA, Koomar JA.. Systematic review of the research evidence examining the effectiveness of interventions using a sensory integrative approach for children. American Journal of Occupational Therapy. 2010; 64(3): 403-414.
Based on a review of 27 studies about SI intervention for children with difficulty processing and integrating sensory information, authors verify that SI approach can result in positive outcomes.

Miller LJ, Coll J, Schoen S. A randomized controlled pilot study of the effectiveness of occupational therapy for children with sensory modulation disorder. American Journal of Occupational Therapy.2007; 61(2): 228-38.
This pilot study suggests that occupational therapy with SI approach can improve skills of children with sensory modulation disorder (exaggerated or insufficient response to sensory environment, or constant sensory seeking).

Miller LJ, Kinnealey M. Researching the effectiveness of sensory integration. Sensory Integration Quarterly. 1993; 21: 2.
Authors note that the effectiveness of SI therapy cannot be answered in an isolated study, but will require collaborative, longitudinal studies with a variety of subjects.

Researchers evaluated effectiveness of the Sensory Integrative Treatment Protocol (SITP) for children with early impairments. The results of this study indicate that SITP is effective in reducing SI issues and helping young children improve preschool performance.

This study concludes that intervention involving SI therapy, neurodevelopmental treatment, and perceptual motor (PM) approach improves sensorimotor functions for children with mild mental challenges. (PM skills are movement related and largely responsible for an individual’s ability to engage in athletic activities and interact with his or her environment.)
