sensory profile in infant/toddler: birth to 36 months

Objectives: sensory processing patterns refer to a person’s ability to receive and respond to sensory events which are important to succeed in daily routine activities. this study aims to determine the sensory processing patterns in infants/toddlers. methods: this is a cross-sectional study. a total of 518 infants/toddlers participated in this study. their ages ranged from birth to 36 months. parents completed the infant/ toddler sensory profile for all participants. results: no significant difference was observed between girls and boys in sensory processing from birth to 6 months; however, there is a significant difference between girls and boys in low registration, sensory sensitivity, and sensory avoidance from 7-36 months. in addition, no significant difference was detected between children born by cesarean and those born through natural childbirth in terms of sensory processing (quadrants and scores) from birth to 6 months and 7-36 months. there is a significant difference between preterm and full-term children (birth to 6 months) in auditory processing. the findings also indicate only a significant difference in oral sensory processing between the preterm and full-term children (7-36 months). discussion: we discussed sensory processing patterns in children and their differences based on different factors. the results of this study can provide considerations for iranian occupational therapists and psychologists.
