Effects of the Connection between Ayres SI Intervention and Home-Based SI on Sensory Processing, Interaction and Task Performance in Children with Developmental Delays

Abstract

Objective: The research is to study the effects of children’s sensory processing, social interactions as well as occupational performance with applications of Ayres SI intervention and home-based SI on children with developmental delays. Method: Ayres SI intervention was administered for 50 minutes once a week for 10 weeks on 4 children aged 3-5 years with developmental delays. The home-based SI program was intervened based on the program provided by the therapist of the primary caregiver for at least 10 minutes per session three times a week for 10 weeks. The results were measured through the sensory profile(SP), evaluation of social interaction(ESI), and Canadian occupational performance measure(COPM). Results: The sensory profile evaluation showed changes from definite differences towards probable differences in the poor registration and inattention/distractibility categories among 9 factors. Also, the emotional reaction, fine motor/perception, sedentary tendency, and oral sensory sensitivity categories revealed shifting tendencies from probable differences to normal differences. In social interactions evaluation, 3 out of 4 children showed a meaningful change of 0.4 to 0.6 logits, COPM in performance, 2 out of 4 children showed significant improvement of 2.2 and 4.4 points before and after the intervention, respectively. In terms of satisfaction, one child showed an increase of more than 2 point from 4.8 points to 8.8 points after intervention. Conclusion: Ayres SI and home-based SI are proven to be affects for children with developmental delays on sensory processing, social interaction, and occupational performance.
