Objective : To explore the effect of intensive sensory integration therapy through daily camp programs for children with sensory modulation disorder. Methods : A comparison of quantitative data and qualitative description between before and after sensory integration therapy camp and main outcome measure was used, including MAP behavior checklist, JSI-2, COPM, sensory history, STEP-SI. Results : The adaptive response was increased and sensory modulation problems were observed less than before the camp. Conclusion : For this study a more diverse, extended and intensive SI program is considered necessary. Further study is needed to develop these findings.
