Abstract

This investigation evaluated the use of sensory information in maintaining stability in individuals with intellectual disabilities. Individuals with mild intellectual disabilities (MID; n = 8), Down syndrome (DS; N = 8), and without intellectual disabilities (WID; n = 8) were evaluated with computerized posturography using the Sensory Organization Test (SOT). Outcomes included an equilibrium composite score, equilibrium scores on six sensory conditions, and sensory ratios for visual, somatosensory, and vestibular systems. Participants were tested with their eyes open or closed while the visual surround, force plate, or combination of both moved to measure influence of sensory information on stability. Based on the data analysis, individuals WID utilize sensory information to a greater extent than did individuals with MID or DS, indicating that sensory information for maintaining stability is deficient among these individuals. To amend this problem and facilitate learning in individuals with intellectual disabilities, practitioners should utilize techniques that maximize variable practice activities using sensory information in different contexts.
