Critique of sensory integration therapy and its application in mental retardation

Studies on the use of sensory integration therapy with mentally retarded persons were critically reviewed. Experimental design and statistical procedures were found inadequate to support the use of this therapy on an empirical basis. In addition, certain methodological and design problems seriously cloud interpretation of research results on this topic. Alternative explanations of positive outcome as well as equivocal findings among studies appear related, in part, to the conceptual foundation of sensory integration therapy. Recommendations for future directions in research and restraint in application were discussed.
