Autism and Occupational Therapy: Sensory and Motor Approaches
Occupational therapy plays a crucial role in supporting individuals with ASD. Discover sensory, motor, and functional approaches to promote their autonomy and quality of life.
Autism Spectrum Disorders (ASD) affect about 1% of the population and are characterized by differences in social communication and repetitive or restricted behaviors. Most autistic individuals also exhibit sensory and motor differences that impact their daily lives. The occupational therapist intervenes to assess these differences and propose tailored support strategies aimed at autonomy and social participation.
🧩 Understanding Autism
Autism is a neurodevelopmental disorder characterized by differences in social communication, interactions, and behaviors. Each autistic person is unique, with their own strengths and challenges. The autism spectrum is very broad, ranging from individuals who require significant support to those who are independent with more subtle differences.
Main Characteristics of ASD
Social Communication
Difficulties in social interactions, non-verbal communication, emotional reciprocity
Restricted Behaviors
Specific interests, routines, repetitive movements, resistance to change
Sensory Differences
Hyper or hyposensitivity to sensory stimuli, seeking or avoiding sensations
Why Occupational Therapy in Autism?
The occupational therapist addresses the functional aspects of autism, specifically the impact of autistic differences on daily activities:
- Sensory Differences: Assessment and sensory regulation strategies
- Daily Autonomy: Learning personal care, dressing, eating
- Fine and Gross Motor Skills: Coordination, handwriting, manipulation
- School Participation: Accommodations, tools, organizational strategies
- Environment: Adapting home, classroom, and living spaces
💡 Positive Approach to Autism
Modern occupational therapy adopts a positive approach to autism, recognizing the strengths and skills of autistic individuals while supporting them in their challenges. The goal is not to "normalize" but to promote autonomy and well-being while respecting autistic identity.
🌈 Sensory Differences in Autism
Sensory differences are present in over 90% of autistic individuals and are now a diagnostic criterion for ASD in the DSM-5. They can involve all sensory systems and manifest as hypersensitivity, hyposensitivity, or modulation difficulties.
The Different Sensory Systems Involved
- Tactile System: Sensitivity to textures, clothing, light touch
- Auditory System: Sensitivity to sounds, difficulties in sound filtering
- Visual System: Sensitivity to light, movement, patterns
- Vestibular System: Balance, perception of movement, motion sickness
- Proprioceptive System: Body awareness, clumsiness, seeking pressure
- Taste and Smell Systems: Food selectivity, sensitivity to odors
- Interoception: Awareness of internal signals (hunger, thirst, pain, emotions)
Sensory Manifestations
Hypersensitivity
Intense reactions to ordinary stimuli, avoidance, sensory overload, meltdowns
Hyposensitivity
Seeking intense sensations, diminished response to stimuli, self-stimulatory behaviors
Fluctuations
Variability of responses depending on context, fatigue, stress
Impact on Daily Life
- Eating: Food selectivity related to textures, tastes, odors
- Dressing: Intolerance to tags, seams, certain fabrics
- Hygiene: Difficulty with water on the face, tooth brushing, nail cutting
- School: Concentration difficulties due to noise, lighting, physical proximity
- Outings: Avoidance of noisy, crowded, overly stimulating places
⚠️ Sensory Overload and Meltdowns
The accumulation of sensory stimuli can lead to overload, manifesting as shutdown or meltdown. These reactions are not "tantrums" but neurological responses to an unbearable environment. Prevention involves identifying triggers and adapting the environment.
💪 Motor Aspects in Autism
Although less known than sensory aspects, motor difficulties are common in autism. They can affect gross motor skills, fine motor skills, and motor planning, impacting autonomy and learning.
Common Motor Difficulties
- Gross Coordination: Atypical gait, clumsiness, difficulties in team sports
- Fine Motor Skills: Difficulties in manipulation, writing, buttoning
- Motor Planning (Praxis): Difficulty learning new movements, sequencing
- Muscle Tone: Hypotonia or hypertonia, postural fatigue
- Motor Imitation: Difficulty reproducing demonstrated gestures
Link Between Sensory and Motor
Proprioception
Poor body awareness affects coordination and motor control
Vestibular System
Vestibular difficulties impact balance and movement
Visual-Motor Integration
Eye-hand coordination necessary for writing and manipulation
"Motor difficulties in autism are often underestimated. However, they significantly impact autonomy and learning. Targeted occupational therapy can make a real difference."

🛠️ Tools for Individuals with ASD
COCO offers cognitive stimulation exercises with a clear and predictable interface, tailored to the differences of autistic individuals.
Discover COCO →🔍 Occupational Therapy Assessment in Autism
The occupational therapy assessment of the autistic individual must be adapted to their communication and sensory processing differences. It combines standardized tools, observations, and interviews with family members.
Assessment Tools
- Dunn's Sensory Profile: Questionnaire assessing sensory processing across different modalities
- AASP (Adolescent/Adult Sensory Profile): Version for adolescents and adults
- M-ABC 2: Assessment of motor skills
- Beery VMI: Visual-motor integration
- Vineland: Assessment of adaptive behaviors and autonomy
- PEDI-CAT: Measurement of functional independence
Areas to Assess
Sensory Profile
Hyper/hyposensitivities, seeking sensations, impact on daily life
Motor Skills
Gross, fine motor skills, praxis, coordination
Daily Autonomy
Personal care, eating, dressing, mobility
Adaptations for Assessment
- Calm Environment: Reduce distracting sensory stimuli
- Predictability: Explain the process, use visual supports
- Extra Time: Respect the individual's pace
- Adapted Communication: Clear, concrete questions, visual supports if needed
- Ecological Observation: Observe in the natural environment when possible
💡 Involve the Individual and Their Family
The assessment should be collaborative. The autistic individual (according to their abilities) and their family are the experts of their daily experiences. Their observations and priorities should guide the assessment and the goals of the intervention.
🎯 Intervention Approaches
Occupational therapy intervention for autistic individuals relies on various approaches based on identified needs. It must always be individualized and respectful of autistic identity.
Sensorial Integration Approach
- Sensory Diet: Regular sensory activity program to maintain optimal alertness
- Sensory Strategies: Tools and techniques to manage hypersensitivities (noise-canceling headphones, fidgets, weighted blankets)
- Environmental Adaptation: Reducing excessive stimuli, creating retreat spaces
- Sensorial Integration Therapy: Sessions in an enriched environment (if specifically trained)
Skill Development
Structured Approach
Learning broken down into steps, visual supports, repetition, positive reinforcement
Specific Interests
Using interests as a lever for motivation and learning
Generalization
Transferring learning to different contexts and with different people
Intervention Principles
- Individualization: Each autistic person is unique; the intervention must be personalized
- Predictability: Clear structure, rituals, anticipation of changes
- Visual Supports: Timetables, action sequences, visual rules
- Respect for Pace: Breaks, processing time, adapting demands
- Valuing Strengths: Building on skills to develop other areas
⚠️ Avoid Non-Recommended Approaches
The HAS recommends prioritizing educational and developmental approaches based on evidence. Some methods have not proven effective or present risks. The occupational therapist should stay informed of updated recommendations.
🏠 Development of Autonomy
The development of autonomy is a major goal of occupational therapy in autism. It concerns daily living activities, mobility, time management, and organization.
Strategies for Daily Activities
- Task Decomposition: Break down each activity into small sequential steps
- Visual Supports: Photos, pictograms, videos showing each step
- Chaining: Forward (learning the last step first) or backward
- Material Adaptation: Choose objects that are easier to manipulate
- Environmental Adaptation: Organize space to facilitate autonomy
Areas of Intervention
Hygiene and Toileting
Washing, tooth brushing, hair care, managing menstrual hygiene
Dressing
Choosing clothes, sequencing, fastenings, adapting to sensitivities
Eating
Using utensils, table manners, dietary diversification
Tools to Aid Autonomy
- Time Timer: Visualization of passing time for transitions
- Visual Sequences: Steps of the routine displayed in order
- Checklists: Lists to check off completed tasks
- Organization Apps: Visual agenda, reminders, timers
