Sensory Processing in Autism Spectrum Disorder
Sensory processing differences (SPDs) are commonly observed in individuals with Autism Spectrum Disorder (ASD), affecting their ability to process and respond to sensory input in a typical manner. According to data, about 90% of people living with ASD also have SPD. This can manifest as atypical responses to sensory stimuli, such as being hypersensitive (over-reactive) or hyposensitive (under-reactive) to sensory input or experiencing fragmented or distorted perceptions.
The sensory processing differences in individuals with ASD can make it challenging for them to filter out irrelevant sensory information and integrate sensory input from different sources. As a result, they may find it overwhelming or difficult to focus in sensory-rich environments. Understanding these sensory processing differences is crucial in providing appropriate support and accommodations for individuals with autism.

Interventions for Sensory Processing
When it comes to addressing sensory processing difficulties in individuals with autism spectrum disorder (ASD), there are various therapeutic approaches and strategies that can be employed. These interventions aim to support individuals in managing sensory issues and improving their overall sensory functioning.
Therapeutic Approaches
Therapeutic interventions play a crucial role in helping individuals with ASD navigate their sensory experiences. Educating caregivers about sensory triggers and reducing environmental factors that contribute to sensory issues are important initial steps. This can involve creating a sensory-friendly environment, minimizing sensory overload, and implementing sensory-based activities to promote sensory integration and regulation.
One approach that has shown promise is sensory integration therapy (SIT). This therapy aims to improve sensory functioning and reduce associated behavioral issues in individuals with ASD. It involves providing individuals with a variety of sensory experiences, such as weighted clothing or materials, interventions providing auditory sensations, and other sensory-focused techniques implemented by licensed professionals, teachers, parents, and other providers.
Occupational therapy (OT) is another therapeutic approach commonly used to address sensory processing difficulties in individuals with ASD. OT focuses on understanding and addressing sensory needs through sensory integration techniques. It aims to help individuals develop skills to cope with sensory challenges and improve their ability to engage in daily activities. OT can also provide guidance and strategies for parents and caregivers to support sensory processing at home [5].
Strategies for Managing Sensory Issues
In addition to therapeutic approaches, there are various strategies that can be employed to help individuals with ASD manage their sensory issues. These strategies aim to provide support and create a sensory-friendly environment that promotes optimal functioning.
One effective strategy is the use of sensory strategies that involve providing specific sensory input to help regulate arousal levels. This can include movement and vestibular input, proprioceptive input, and deep-pressure tactile input. These strategies help individuals with ASD regulate their sensory experiences and promote optimal participation in tasks, including communication.
It is important for individuals with ASD and their families to collaborate with professionals, such as occupational therapists and speech therapists, to develop personalized sensory management plans. These plans may incorporate a combination of therapeutic interventions, sensory strategies, and accommodations to support individuals in their daily lives.
By implementing therapeutic approaches and employing strategies for managing sensory issues, individuals with ASD can improve their sensory functioning, reduce sensory-related challenges, and enhance their overall quality of life. It is important to seek professional guidance and support to tailor interventions to the specific needs of each individual with ASD.

Hyperreactivity vs. Hyporeactivity
Hyperreactivity refers to an oversensitivity or heightened response to sensory stimuli. Autistic individuals with hyperreactivity may exhibit behaviors such as avoiding sensory experiences, expressing distress through crying or withdrawal, covering their ears or eyes, or appearing restless, stressed, or irritable in response to sensory input [7]. They may have difficulty filtering out irrelevant sensory information, resulting in an overwhelming sensory experience.
On the other hand, hyporeactivity refers to undersensitivity, where individuals have reduced sensitivity or awareness of sensory input. Autistic individuals with hyporeactivity may seek out sensory experiences, such as touching different textures, exploring things by touch, enjoying tight hugs, or wearing tight-fitting clothing [7]. They may require more intense sensory input to register and respond to stimuli.
Effects on Daily Life
These sensory sensitivities can have significant effects on the daily lives of individuals with autism. The challenges they face in processing sensory information can impact their behavior, emotions, and overall well-being.
For individuals with hyperreactivity, everyday environments may be overwhelming due to heightened sensitivity to sounds, lights, textures, smells, or other sensory stimuli. This can result in stress, anxiety, or even meltdowns in response to sensory triggers. It may also lead to avoidance behaviors, where individuals actively try to limit exposure to sensory input that causes distress.
On the other hand, individuals with hyporeactivity may seek out intense sensory input to feel more connected to their environment. They may engage in repetitive behaviors or seek out specific sensations to compensate for their reduced sensitivity. This can include behaviors like increasing music volume or speaking loudly in response to sensory stimuli.
It's important to note that sensory sensitivities can vary among individuals with autism. Some may experience a combination of hyperreactivity and hyporeactivity across different sensory modalities, while others may have more pronounced sensitivities in specific sensory domains. Understanding and addressing these sensory sensitivities is crucial to creating supportive environments and promoting the well-being of individuals with autism.
In the following sections, we will explore interventions and strategies that can help manage sensory processing difficulties in autism, as well as the role of professional support, such as occupational therapy and a multi-disciplinary approach.
Professional Support for Sensory Challenges
When it comes to addressing sensory challenges in individuals with autism, professional support can play a crucial role in improving their sensory processing abilities. Two key approaches for seeking professional support are occupational therapy and a multi-disciplinary approach.
Occupational Therapy
Occupational therapy (OT) is a commonly utilized intervention for individuals with autism spectrum disorder (ASD) who experience sensory processing difficulties. OTs work closely with children to address their sensory processing differences using interventions such as sensory integration and sensory-based strategies. These strategies aim to help children organize environmental input and perform daily activities, such as jumping, swinging, and weight-bearing activities [6].
Sensory strategies implemented by occupational therapists can be tailored to meet the unique needs of individuals with ASD. These strategies may involve providing specific movement or vestibular input, proprioceptive input, and deep-pressure tactile input to help regulate arousal levels and enhance participation in tasks like communication [6]. Through occupational therapy, individuals with autism can develop skills to navigate their sensory world more effectively.
