Q: How are sensory integration theory, sensory integration dysfunction, Sensory Processing Disorder, and Sensory Modulation Disorder related? A: Sensory integration theory was formulated by A. Jean Ayres, PhD, OTR, an occupational therapist who practiced from the mid-1950s until 1988. Based on neuroscience principles, the theory describes an underlying rationale for the diagnosis and treatment approach that Dr. Ayres founded to evaluate and intervene with children who have particular sets of sensory and/or motor symptoms and who may have learning disabilities. Her basic concept was that the individual had a deficit in the central nervous system's ability to receive, filter, organize, and integrate stimuli, which resulted in a non-adaptive response. Sensory integration dysfunction (DSI) was the term used by Dr. Ayres to refer to this broad theory, as well as to the diagnosis and the treatment (e.g., sensory integration treatment) of children who have the dysfunction. These terms and the relationships between them have been clarified for the purposes of this web site. The current terminology is explained below. "Sensory integration" is now recommended for use only to refer to Dr. Ayres' theories about mechanisms of the disorder and their intervention. Intervention is now referred to as "occupational therapy (OT) with a sensory-based (or SI, sensory integration) approach," or "OT using Ayres' sensory-based (or sensory integration) approach." Sensory Processing Disorder (SPD) is the label used on this web site to denote the diagnosis of difficulty in processing sensory input in an efficient and accurate manner, and includes the accompanying behavioral, attentional, motor, and functional manifestations. Sensory Modulation Disorder (SMD) is one of the three primary subtypes of Sensory Processing Disorder. Individuals with SMD have difficulty adjusting their responses to match the needs of the situation. They often have patterns of over-responsivity, under-responsivity, or sensory-seeking (or a combination of those patterns) in response to levels of stimulation that typically developing individuals respond to with a brief orienting response (noticing the new stimulus) and then habitation (ignoring the new stimuli) once it is interpreted as non-threatening.

Q: How can I assess Sensory Processing Disorder if I'm not certified in administration of the Sensory Integration and Praxis Tests (SIPT)? A: The basis of all occupational therapy assessment is to evaluate the impact of underlying components, including sensory integrative function, that affect an individual's functional performance in the context of specific settings in which the individual must perform. In addition to the Sensory Integration and Praxis Tests (whose use may be limited due to a child's age or ability to understand the test directions), clinical observations and sensory history questionnaires can provide information about sensory integration (see Cook, 1991; Dunn & Westman, 1997; Royeen & Fortune, 1990). Many standardized perceptual and motor tests (see Carrasco, 1993) also provide an opportunity to observe aspects of sensory integrative function. For advanced clinicians who desire to develop or enhance their diagnostic skills, the SPD Foundation offers a five-day mentorship program that includes training in choosing appropriate tools to evaluate children with SPD; administering, scoring, interpreting ,and writing up standardized scales reliably; and interpreting findings from evaluations for treatment planning. The program is AOTA-approved for continuing education credit. Learn more about the program at Advanced Mentorship Program. .

Q: Are children entitled to Sensory Processing Disorder therapy in school by law? A: The Individuals with Disabilities Education Act (IDEA) guarantees a free and appropriate public education with peers, to the maximum extent appropriate, to all eligible children with disabilities (ages 3-21) who need special education and related services in order to learn in school. Children with disabilities can receive occupational therapy (OT) if they qualify for special education. In addition, a school team, including the parents, must decide if the therapy is necessary. (Some school districts will provide OT in other instances, e.g., to give teachers suggestions before referring a child to special education, called a pre-referral.) There are no provisions in state or federal law that specify how OT, once recommended by the team, must be provided. This includes the service model, frequency of intervention, and the frame of reference. In due process hearings and the courts, the issue of theory base or frame of reference has been referred to as a methodology decision. One of the latest court decisions regarding methodology centered around individual instruction for a student with dyslexia using the Ortho-Gillingham method (E.S. v. Independent Sch. Dist. No. 196). The district court disallowed the parent's request for this kind of reading instruction, stating that schools have discretion over methodology decisions as long as the program provides a free and appropriate public education. Therapists who recommend school-based sensory integration therapy must show how the student needs this kind of occupational therapy in order to benefit from participation in the curriculum and specific school activities. Important issues to address (in jargon-free language) include:
Q: How can I best apply Sensory Processing Disorder principles in school settings? A: The effective application of Sensory Processing Disorder (SPD) principles in school settings is an important role for occupational therapists. When you are in this situation, try to focus on articulating the educational benefit for the student and planning interventions that will improve outcomes related to the student's role in a school setting (e.g., develop goals and objectives for increasing attention for school tasks versus reducing sensory defensiveness). Use consultation and integrated therapy within the classroom to help teachers and parents reframe their perspectives about the student's behavior and abilities as well as adapt the school environment, the educational task, and specific materials used in lessons. Mailloux (1997) states "..it is also the job of the occupational therapists to educate the team about how sensory integrative disorders are affecting the child's educational performance and how appropriate intervention based on sensory integrative concepts can be incorporated into all aspects of their educational program."

Q: How can I assess the sensory integrative function of children from birth to 3 years of age? A: Gather your information from several sources. Most important are the child's parents and child care provider. Interview them to find out how processing of sensory information affects the child's interaction with others, sleep/wake cycles, and play and eating behaviors (DeGangi et al, 1995; Jirgal, Bouma, 1989). Clinical observation and a thorough knowledge of sensory integration theory and typical and atypical development are also essential. Although formal tests may be difficult to administer to very young children, DeGangi and Greenspan (1989) have a test of sensory integration function, and Miller (1994) has developed assessments of the quality of movement based on SI and neurodevelopmental therapy principles for this age group. Many other developmental tests also contain items that provide information about an infant's sensory processing, coordination, and motor planning abilities (see Stallings, 1993, for a description of items for birth-3 in these tests). The SPD Foundation offers a five-day mentorship program in advanced clinical assessment and treatment of SPD. The program is AOTA-approved for continuing education credit.
