This project investigated the prevalence of sensory processing problems in a clinical group and also examined the clinical effectiveness of a specialised therapeutic technique, sensory integrative therapy (SIT), in the treatment of maladaptive behaviours in two adults with learning disabilities. The Sensory Integration Inventory - Revised for Individuals with Developmental Disabilities (SII-R, Reisman and Hanschu 1992) was used to identify two clients suspected of having poor sensory processing. A single-subject experimental design (ABAB) was used to assist the objective measurement of the effects of SIT. The results suggest that the SII-R has some limitations in identifying clients who would benefit from SIT. One client (Ms D) was seen to instigate more positive interactions with her environment during and following the treatment phases; however, the overhabituated behaviours of the other client (Mr K) showed little response to SIT. These results are discussed in the form of a practitioner's update, with respect to the indicators of sensory processing dysfunction and the potential therapeutic benefits of SIT as an adjunct to therapeutic interventions for individuals with learning disabilities.
