Introduction

Sensory integration treatment (SIT), based on Ayres's theory (ASI) of sensory processing, is typically offered by occupational therapists.¹ The process through which a person takes in and arranges their senses from their surroundings, gives them context, and aids develop the skills necessary to engage in everyday activities is known as sensory integration.² In sensory integration treatment and sensory integrative dysfunction, the two main types of dysfunction that are compared and contrasted are dyspraxia and sensory modulation dysfunction.

An occasional feeling of anxiousness is common in life. Concerns about one's health, finances, or family issues are common. However, anxiety disorders encompass more than just fleeting fear or worry. People who suffer from anxiety disorders often experience persistent anxiety that may worsen with time. The symptoms may make it difficult to carry out regular tasks including relationships, employment, and schooling.

Anxiety disorders come in a variety of forms, such as panic disorder, social anxiety disorder, generalized anxiety disorder, and other disorders connected to phobias.³

Anxiety is a common symptom of Sensory Processing Disorder (SPD). It is the extra reward that no one desires.

Anxiety and SPD interact with one another to produce a cascade of symptoms.⁴

Sensory integration

Sensory integration is the organisation, processing, and integration of sensory data from the body and surroundings.

Put simply, this refers to how our senses perceive, process, and respond to information—or not—that reaches our ears. All the daily tasks we have to complete, such as getting dressed, eating, moving around, interacting with others, learning, and working, depend on sensory integration.

Our senses provide us with sensory data, which includes:

• Visual
• Auditory
• Tactile
• Gustatory
• Olfactory
• Proprioceptive
• Vestibular
• Interoception⁵

Although there are eight systems involved in sensory integration, the following three are the most adversely affected when a person struggles with sensory processing:

• The tactile system perceives touch sensations through the skin, such as pressure or temperature
• The proprioceptive system tells us where we are in relation to other people, through our muscles and joints
• The vestibular system, which controls human balance and movement, is made up of an intricate organ in the ear⁶

Throughout our lives, the automatic brain process of sensory integration, also known as sensory processing, takes place. Normal childhood activities help children acquire sensory integration, but for some, this process is less effective and can impact daily activities.⁵

Role of occupational therapist

Occupational therapists are extremely important when it comes to helping people manage their sensory complaints. The following individuals may gain the most from occupational therapy, according to the American Occupational Therapy Association (AOTA):

Occupational therapy can enhance various areas of early life, including playtime, sleep, food, and socialization, for infants and toddlers.

• Children of school age: Occupational therapy can enhance various aspects of school-age children's lives, including self-care, academic performance, socialising, and focus
• Teens: Occupational therapy can assist teenagers in developing other skills that are crucial for young adults, such as driving, independence, and even interpersonal connections
• Adults of any age: Occupational therapy can help adults of any age with their relationships, job, education, and leisure, especially those diagnosed later in life⁶

Techniques and exercises

• Play-based activities: In SIT, play serves as the main medium. To test a child's capacity for sensory processing, occupational therapists create engaging exercises with a range of sensory inputs. Playing with swings, trampolines, big balls, and other equipment that provides sensory input is one way to engage in these activities
• Engaging in activities involving swinging and spinning is a popular way to give vestibular (balance and movement) input. These exercises can help kids become more balanced and coordinated while controlling their arousal levels
• Deep pressure activities: By applying pressure to the child's body, such as squeezing them or covering them with a blanket, you can provide them proprioceptive input, which promotes body awareness and calmness
• Brushing protocol: The Wilbarger Brushing Protocol calls for applying deep pressure to the child's skin with a soft surgical brush. This method enhances sensory processing and lessens tactile defensiveness
• Weighted vests and blankets: Deep pressure and proprioceptive input are applied using weighted vests and blankets. They can support kids in feeling more centered and grounded
• Therapeutic listening: Using music that has been particularly created to boost a child's auditory system is known as therapeutic listening. It is thought to improve self-regulation and sensory processing
• Visual stimulation: Playing with coloured lights or tracking moving objects are two examples of visual stimulation activities that might enhance attention and visual processing
• Oral motor activities: Activities that involve the mouth, such as blowing bubbles or chewing food, can enhance oral sensory processing and assist in speaking and eating
• Changes to the environment: Occupational therapists might advise changing the child's surroundings to lessen sensory disturbances or provide chances for sensory exploration
• Sensory diet: A sensory diet is a personalized strategy that combines sensory activities into the child's daily routines to suit their sensory needs and promote involvement in everyday activities²

Study and research

It is difficult to pinpoint the exact prevalence because sensory integration difficulties can co-occur with other diagnoses (such as autism, ADHD, OCD, genetic syndromes, and learning disabilities), as well as with no other diagnosis at all. 

A 2009 study found that 1 in 6 children has sensory processing issues that make it difficult for them to learn and function in school; other studies have found that 66% of children with special education needs (who were not autistic) and 32% of children with autism show distinct differences in sensory behaviours; and a 2020 paper found that sensory processing difficulties predicted executive and cognitive dysfunctions in inhibitory control, auditory sustained attention, and memory.⁵

There is still a need for more study on the subject; the few studies that do exist suggest that it may be a useful treatment.

That does not exclude sensory integration treatment from being useful in assisting certain individuals in managing their sensory complaints, though.

The American Academy of Pediatrics advises ensuring you have a method to monitor the efficacy of sensory integration treatment if you're considering getting it for a loved one. This entails setting clear treatment objectives with an experienced occupational therapist and monitoring the therapy's effectiveness in achieving those objectives.⁶

Drawbacks

Dysfunction of sensory modulation

The brain's capacity to select and focus on the sensory data it needs to interpret the information needed to complete a job is known as sensory modulation. When we modulate well, we can block out sensory information unrelated to the job at hand.

Dyspraxia 

Dyspraxia describes a person who struggles with motor planning and execution, which can impair their capacity to carry out coordinated motions.

Differences in one or both areas of sensory integration may be experienced by certain individuals.

FAQs

What is the difference between sensory integration and sensory processing?

The brain processes that enable us to receive messages from our senses, interpret them, and react correctly are referred to as "sensory integration" and "sensory processing."

What are the conditions treated with sensation integration therapy?

When treating disorders like autism spectrum disorder (ASD), attention deficit hyperactivity disorder (ADHD), sensory processing disorder (SPD), developmental coordination disorder (DCD), learning disabilities, intellectual disabilities, behavioural disorders, motor skill delays, anxiety disorders, and developmental delays, sensory integration therapy (SIT) is frequently used in conjunction with other therapies and interventions that are customized to meet the specific needs of each patient.

Summary

Sensory integration therapy holds promise as a complementary approach for managing anxiety by addressing sensory processing difficulties. Despite needing more extensive research, existing evidence suggests its potential benefits. By targeting sensory sensitivities, this therapy aims to regulate the nervous system, potentially reducing anxiety symptoms. Incorporating sensory-based activities, environmental modifications, and relaxation techniques, provides individuals with strategies to cope with anxiety triggers effectively.

Collaboration with occupational therapists ensures tailored interventions that cater to individual needs. Integrating sensory integration therapy into existing treatment plans offers a holistic approach to anxiety management, potentially enhancing therapeutic outcomes. However, the effectiveness of this therapy may vary among individuals, emphasizing the importance of personalized approaches.

Continued research and refinement of sensory integration techniques are crucial to better understand its mechanisms and optimize its application in anxiety treatment. Overall, sensory integration therapy represents a promising avenue for alleviating anxiety symptoms and improving the overall well-being of individuals with anxiety disorders.

Pediatric occupational therapists can help children with a variety of developmental disorders with their sensory issues by offering Sensory Integration Therapy (SIT), a helpful intervention based on Ayres's theory of sensory processing. SIT methods provide a holistic approach and include play-based activities, swinging, deep pressure, brushing, and more.

SIT can improve functionality and quality of life for kids with disorders like ADHD, autism spectrum disorder, and sensory processing issues. Working together, therapists, parents, and medical professionals can ensure individualized treatment and positive results.²
