Brief Summary:
Children with Sensory Modulation Dysfunction (SMD) either over- or under-react to stimuli in their environment. This can cause significant problems with daily activities and may lead to anxiety, poor attention, low self-esteem, and further complications in motor, cognitive, social and emotional development. Diagnosis of SMD is based on physiological responses to specific stimuli, measures of behavioral/social/emotional symptoms, and studies of the resulting functional limitation and disability. Treatments involve direct biomedical and behavioral intervention to improve sensory processing, as well as adjustments to the home, school and community environment. This study will compare the effect of occupational therapy vs. alternative therapy on the reactivity and function of children who have SMD.

Sensory Disorders Behavioral: Occupational Therapy Phase 2

Detailed Description:

This single masked, crossover trial will randomize children with Sensory Modulation Dysfunction (SMD) to either Occupational Therapy (OT), alternative treatment (Activity Protocol), or delayed treatment (initially the control group). Children are assigned to one of the three treatment groups using a random numbers table with block randomization. Assignments are made by the research assistant, who is masked to assessments, parent priorities, and family needs/characteristics. Using block procedures, the first child is randomly assigned to treatment group A, B, or C. The next child entered to the study at that age, gender and socioeconomic status (parents' education) is randomly assigned to one of the two remaining groups. The third child meeting age, gender and SES criteria is automatically assigned to the remaining group. This procedure reduces seasonal confounds and chance variation between group characteristics. The order of treatment by group is: GROUP A (OT - 1st 10 weeks; Activity - 2nd 10 weeks); GROUP B (Activity - 1st 10 weeks; OT - 2nd 10 wks); GROUP C (Wait list - 1st 10 weeks; OT - 2nd 10 wks; Activity - 3rd 10 wks). Inclusion in the study is based on standardized assessments of physiological reactivity after a "Sensory Challenge Protocol", a technique developed by this research group and published in several medical journals. Standardized measurements of physiologic, behavioral and emotional status, are administered before treatment, after each treatment condition, and after all treatments are completed by investigators masked to treatment; and including the following:

Measurements in the Impairment: The Sensory Challenge protocol is a laboratory paradigm in which the child's physiologic reactivity after sensation is tested using electrodermal reactivity and vagal tone indices to assess sympathetic and parasympathetic systems. Measurements of functional limitations include aggression, withdrawal, impulsivity, hyperactivity, inattention, and sensitivity to tactile, movement, taste, smell, auditory and visual stimuli. These are measured in the areas: (1) attention (subscales of the parent-report Child Behavior Checklist [CBCL],and Leiter International Performance Scale-Revised; the Continuous Performance Task, the StopTask and the Go-No Go Task); (2) emotion (the CBCL); (3) sensation (the Short Sensory Profile; the Leiter-R; the Multidimensional Anxiety Scale for Children; the Stop Task; the Go-No-Go Task; the Auditory Continuous Performance Test). Measures of the Disability Dimension include the Vineland Scales of Adaptive Behavior, the Goal Attainment Scale, and play and dinner-time paradigms. Finally, measures in Societal Limitations Dimension include a parent semi-structured interview and the Visual Analogue Scale.

Occupational therapy is a targeted protocol involving functional and sensory-integration activities, supported by family-based activities at home.
