Sensory Integration Test

• SIT was introduced by Jean Ayres introduced in 1963.
• It is defined as “the organization of sensory information for use”.
• It assumes that some children have ‘sensory integration dysfunction” leading to difficulties in regulating sensory info.
• This SI dysfunction causes difficulties in a variety of functions (learning new skills, organizing themselves, engaging in positive social experiences)….etc.
• Sensory integration therapy is supervised by occupational therapists (OTs).
• Examples of SI techniques: brushing, compression, weighted vests, and sensory diets.
• While children with autism have documented sensory problems, evidence for SIT is not convincing.

Research Summary: Most of the studies published on SIT did not find significant effects for this kind of treatment. Moreover, this type of therapy is very expensive and there are other treatments that were found effective in managing the same types of disorders (such as ABA and function based interventions).

ASLL Recommendations: Not recommended due to lack of evidence and the availability of other treatments.
