Autistic children with sensory differences
Sensory channels that can be affected
Sensory tools and OT assessment
Sensory processing differences in autism range from mild sensitivities to profound dysregulation that affects daily function. Children may be hypersensitive (over-reactive), hyposensitive (under-reactive), or both — depending on the sensory system and context.
Sensory accommodations can be written into your child's IEP. The Ontario Human Rights Code requires schools to accommodate sensory needs as part of the duty to provide equal access to education.
Sensory break room or calm-down space
Designated quiet area for self-regulation during the school day.
Movement breaks
Scheduled activity breaks to meet proprioceptive and vestibular needs.
Noise-cancelling headphones
Permitted during loud activities, assemblies, or independent work.
Preferential seating
Away from high-traffic areas, windows, or noise sources.
Modified lighting
Avoid fluorescent flicker; allow hats or sunglasses for photosensitivity.
Sensory tools at desk
Fidget tools, resistance bands on chair legs, wiggle cushions.
Occupational therapists use sensory integration therapy to help autistic children process and respond to sensory input more adaptively. Treatment includes individualized sensory diets, therapeutic equipment activities, and environmental modification recommendations.
