First-Line Treatment for Sensory Processing Disorder
Occupational therapy (OT) using sensory integration techniques is the first-line treatment for sensory processing disorder, focusing on graded sensory exposure, environmental modifications, and activity-based interventions to improve functional participation in daily activities. 1
Evidence Base and Treatment Framework
The treatment approach stems from Jean Ayres' sensory integration theory, which posits that organizing sensory input through therapeutic activities can improve behavioral and functional responses 2. However, it is critical to understand that sensory processing disorder should generally not be diagnosed as a standalone condition 3. Sensory processing difficulties are characteristics commonly seen in other developmental and behavioral disorders including autism spectrum disorders, ADHD, developmental coordination disorders, and anxiety disorders 3.
Core Treatment Components
Sensory-Based Occupational Therapy Interventions
The primary intervention involves OT assessment and treatment using:
Sensory grounding techniques that keep individuals present in the moment through environmental awareness (noticing colors, textures, sounds), cognitive distractions (word games, counting backwards), and tactile stimulation (textured items, rubber band flicking) 1
Graded sensory exposure using brushes, swings, balls, and specially designed therapeutic equipment to provide vestibular, proprioceptive, auditory, and tactile inputs 3
Environmental modifications to reduce sensory overload, including quiet spaces with dimmed lighting and reduced auditory stimulation 1
Assessment Tools
Occupational therapists should utilize standardized assessments including:
The Adolescent/Adult Sensory Profile (AASP) to characterize sensory processing patterns across four quadrants: low registration, sensory sensitivity, sensory seeking, and sensory avoidance 4, 5
The Canadian Occupational Performance Measure (COPM) to identify functional goals 4
The Sensory-Motor Preference Checklist for treatment planning 4
Treatment Dosage and Expected Outcomes
Clinical improvement correlates positively with the number of treatment sessions received 5. In a retrospective cohort study, 62% of patients with functional neurological disorder and sensory processing difficulties showed clinician-determined improvement following sensory-based OT intervention 5. The treatment should focus on:
Addressing hypersensitivity to touch, light, sound, and movement as these become maintaining factors that limit functional participation 1
Preventing avoidant behaviors that exacerbate symptoms and disability 1
Improving participation in activities of daily living through individualized sensory-based treatment plans 4
Critical Caveats and Limitations
Parents and clinicians must be informed that research regarding sensory integration therapy effectiveness is limited and inconclusive 3. The American Academy of Pediatrics states that while sensory-based therapies may be acceptable as one component of a comprehensive treatment plan, the evidence base remains weak 3.
Important Clinical Considerations:
Always evaluate for underlying developmental and behavioral disorders before attributing symptoms solely to sensory processing difficulties 3
Implement a trial period of therapy with clear functional goals and objective measures of progress 3
Avoid over-reliance on equipment or aids that may interrupt normal automatic movement patterns and create maladaptive functioning 1
Address comorbid conditions including anxiety, which commonly co-occurs and may independently predict sensory processing difficulties 5
Practical Implementation Strategy
Complete comprehensive evaluation for autism spectrum disorder, ADHD, anxiety disorders, developmental coordination disorder, migraine, and cognitive complaints, as these conditions predict individual differences in sensory processing patterns 5
Initiate OT with sensory-based interventions focusing on functional activities rather than isolated sensory exercises 1
Modify environments to reduce sensory overload while gradually increasing tolerance through graded exposure 1
Monitor progress using standardized outcome measures and functional participation metrics 4, 5
Adjust treatment intensity based on response, recognizing that more sessions correlate with better outcomes 5
The treatment should prioritize real-world functional improvements in daily activities, social participation, and quality of life rather than isolated sensory responses 4, 5.
