ABSTRACT

Objective: The aim of this study was to identify the characteristics and analyze the quality level of studies regarding the effectiveness of sensory integration therapy on feeding and oral function through a single-subject research design. Methods: A total of seven studies were chosen through the Research Information Sharing Service (RISS) and Korean Studies Information Service System (KISS). Keywords were sensory integration, sensory integration therapy, sensory stimulation, and oral defensiveness. The characteristics and quality level were analyzed. Results: A reversal design was used in every study. Sensory integration therapy and oral related intervention were used at the same time. After intervention, dependent variables such as feeding, breathing, posture, drooling, and brushing teeth were increased. The treatment time, number of minutes, and duration varied. The quality level was moderate overall. Conclusion: The effectiveness of sensory integration therapy on feeding and oral function was identified. The quality level of single-subject design research was deemed appropriate. A high quality level of study should be executed using an extra method for increasing the validity in the future.
