Changes in Social Maturity and Activities of Daily Living Following Vestibular- and Proprioceptive-Based Sensory Integration Therapy in Adults with Developmental Disabilities: An Exploratory Study

Abstract

Objectives This study aimed to explore the clinical applicability of sensory integration intervention to promote functional independence and social participation in adults with developmental disabilities. Methods This single-group study retrospectively analyzed clinical data from four adults with developmental disabilities pre- and post-intervention. Vestibular and proprioceptive-focused sensory integration therapy was administered. The Vineland Social Maturity Scale (VSMS) and Modified Barthel Index (MBI) were used to evaluate changes before and after the intervention. Results Both VSMS and MBI mean scores showed a slight increase; however, no statistically significant differences were found. Conclusions Although no statistically significant changes were observed, positive trends were noted in some participants. These findings suggest the potential for functional improvements following sensory integration therapy in adults with developmental disabilities. Future prospective studies with larger sample sizes and control groups are warranted.
