Objective : The purpose of this study was to investigate the effects of sensory diet home program for children with autism spectrum disorder who have sensory defensiveness and explore how this intervention affect to sensory modulation and social interaction ability.
Methods : The subject of this case study was a 12-year-old girl with autism spectrum disorder who was struggling with her sensory modulation problem. Parent interview and evaluations were conducted and subject-tailored sensory diet home program was made by the therapist. Parent education for the home program was provided to parents and everyday, 3 times, 30minutes of home program activities were conducted to the child for 23 days. Adolescent/Adult Sensory Profile and Social Maturity Scale were measured at pre and post intervention and parent wrote daily observation record about child during the intervention.
Results : After the intervention, Low Registration, Sensory Sensitivity, Sensation Avoiding area of Adolescent/Adult Sensory Profile included to the normal range and the scores of the Social Maturity Scale improved.
Conclusions : Child’s sensory defensiveness was relieved and sensory modulation and controling emotion ability were improved. While there was significant improvement for sensory modulation and social interaction ability, this was a case study and there was only one subject. So we need to study with larger sample size to generalize this intervention’s effectiveness.
