This research study evaluated the sensory and motor skills of a group of children with Asperger's Syndrome (AS) and Pervasive Developmental Disorder - Not Otherwise Specified (PDD-NOS). It also examined the efficacy of a 10-week intervention using sensory integration therapy. In a one-group, pretest-posttest design with a delayed treatment approach, nine children were assessed using the Asperger Syndrome Diagnostic Scale, the Perceived Efficacy and Goal Setting System, Clinical Observations, the Sensory Profile, the Bruininks-Oseretsky Test of Motor Proficiency, Second Edition and the Sensory Integration and Praxis Tests. Testing was repeated after a five-week baseline phase during which children and families followed their normal daily routines. Next, sensory integration therapy was provided twice a week for 10 weeks. A treatment manual provided treatment options that could be used based on individual client needs. The tests were repeated after the intervention period and results were analyzed using repeated measures ANOVA. Prior to intervention, all children were identified as having sensory and motor impairments that were greater than typically developing children, particularly in the areas of sensory processing, inattention, distractibility, sensory modulation, emotional and behavioral responses to sensory input, coordination, praxis and standing and walking balance. Six children completed the study. Following intervention, significant improvements were identified in sensory processing, modulation of sensory input, praxis and balance compared to pre-intervention findings. This provides preliminary quantitative evidence that sensory integration therapy may be a useful strategy to improve the sensory and motor skills that are identified in children with AS and PDD-NOS.
