This pilot study aims to identify behavioral and neural measures of sensory processing and attention associated with routine occupational therapy intervention for children with autism spectrum disorders. Specifically, the investigator will examine the impact of a child's level of engagement during therapy using standardized behavioral and electroencephalography (EEG) measures of sensory processing.
Occupational therapy is one of the most frequently requested and highly utilized interventions for children with autism spectrum disorders (autism) and therapists have consistently reported using the sensory integration framework as a dominant theory guiding practice. A key component of sensory integration theory is the child's active engagement during therapy, which is assumed to improve neural function, behavior, and participation. However, no studies have examined the neural mechanisms associated with occupational therapy interventions among children with autism.
This pilot feasibility study will examine behavioral and electroencephalography (EEG) measures of attention and sensory processing before and following 6-8 weeks of routine occupational therapy at community outpatient centers among 30 children with autism aged 6 - 13 years. The primary aim is to determine the feasibility, sensitivity, and validity of EEG measures of auditory processing as a response biomarker following routine occupational therapy intervention. Another aim is to examine the contribution of a child's engagement during therapy as a key predictor of change using behavioral and EEG outcome measures. The occupational therapy intervention consists of one-hour weekly sessions of usual care at Nationwide Children's Hospital outpatient centers.
Results from this grant will provide valuable proof-of-concept data establishing engagement during therapy as an active ingredient in occupational therapy intervention using neurophysiological and behavioral measures. These results will also establish the validity of EEG measures as sensitive to a child's level of engagement and neuroplastic changes following occupational therapy intervention.

| Occupational Therapy | Behavioral | Children with autism will receive 6 - 8 weeks of regularly scheduled occupational therapy at Nationwide Children's Hospital outpatient centers. The intervention consists of one-hour weekly sessions with a licensed occupational therapist. |
| Measure | Description | Time Frame |
|---|---|---|
| EEG: Changes in Sensory Gating event-related potential (ERP) measures. | Amplitudes and latencies of the P50 and N1 ERP components from the sensory gating paradigm. The P50 component presents as a positive deflection that occurs around 40-80 milliseconds (ms) after click onset and the N1 represents a negative deflection occurring around 100 ms. Gating will be assessed using difference scores wherein the amplitude of click 2 is subtracted from the amplitude of click 1. | 8 weeks |
| EEG: Changes in Sensory Gating neural oscillations | Evoked and phase-locked Beta power (13-18 Hz) and Gamma power (30-50 Hz) following click onset will be examined. | 8 weeks |
| EEG: Changes in Sensory Registration event-related potential (ERP) | The Sensory Registration paradigm consists of four tones of different frequencies and intensities. Amplitude and latency of the P1, N1, P2, N2, and P3 ERP measures following the four tones of the sensory registration paradigm will be examined. | 8 weeks |
| Changes in behavioral measure of Social Responsiveness | The Sensory Responsiveness scale - 2 (SRS-2) is a standardized parent-report measure and will be used to measure social responsiveness. | 8 weeks |
| Changes in behavioral measure of Sensory Processing | The Sensory Profile - 2 (SP2) is a standardized parent-report measure and will be used to measure sensory processing. | 8 weeks |
| Changes in behavioral measure of Attention | The Test of Everyday Attention for Children 2 (TEA-Ch2) will be used to measure attention. The TEACh2 is a standardized performance-based measure. |
| Measure | Description | Time Frame |
|---|---|---|
| Changes in Behavioral measures of executive functioning | The Behavior Rating Inventory of Executive Function-2 (BRIEF-2) is a standardized parent-report measure of executive functioning. | 8 weeks |
| Changes in behavioral measure of Adaptive behavior |
