Understanding Tactile Defensiveness

Tactile defensiveness, also known as tactile hypersensitivity or tactile sensitivity, is a condition characterized by an overresponsiveness to tactile input. Individuals with tactile defensiveness may perceive certain tactile sensations as noxious or uncomfortable, leading to purposeful avoidance or a decrease in behavior organization as a response. This condition is often associated with sensory processing disorder, a condition that affects how the brain processes sensory information.

Definition of Tactile Defensiveness

Tactile defensiveness, also known as hypersensitivity to touch, refers to an increased sensitivity to touch compared to others. Individuals with tactile defensiveness may exhibit various reactions to touch, such as being bothered by certain fabrics or clothing textures, experiencing discomfort when wearing shoes, avoiding messy textures like finger paint, and being averse to certain types of touch, such as hugs and kisses.

Sensory Processing Disorder Overview

Tactile defensiveness is considered a specific deficit within the larger umbrella of sensory integration. Sensory integration refers to the body's ability to receive, interpret, and respond to sensory information from the environment. When there are deficits in sensory integration, an individual's response to sensory input may not be functional [1].

Sensory processing disorder (SPD) is a condition that affects the way the brain processes sensory information. Individuals with SPD may be oversensitive or undersensitive to various sensory stimuli, including touch, sound, and light. Tactile defensiveness is one aspect of sensory processing disorder, specifically related to an overreaction to light touch sensations, which can trigger a fight or flight response in some individuals.

Understanding tactile defensiveness and its association with sensory processing disorder is important in recognizing and addressing the challenges faced by individuals who experience hypersensitivity to touch. By gaining a deeper understanding of these conditions, individuals, caregivers, and professionals can better support those with tactile defensiveness in their daily lives.

Causes and Symptoms of Tactile Defensiveness

Tactile defensiveness, also known as tactile hypersensitivity or tactile sensitivity, is characterized by an overresponsiveness to tactile input, where specific tactile sensory input may be perceived as noxious, leading to purposeful avoidance or a decrease in behavior organization as a response.

This hypersensitivity can manifest in various ways, such as being bothered by certain fabrics or clothing textures, having difficulty with wearing shoes, avoiding messy textures like finger paint, and being averse to touch such as hugs and kisses [3].

Neurological Factors

Tactile defensiveness is thought to be a result of neurological factors, specifically an overreaction of the nervous system to light touch sensation. The brain pays excessive attention to light touch and protective sensations from the skin, interpreting ordinary touch sensations like clothing textures or hugs as threats. This heightened sensitivity can trigger a fight, flight, or freeze response, leading to meltdowns, arguments, and avoidance of touch.

Behavioral Indicators

The behavioral indicators of tactile defensiveness can vary from person to person. Some common symptoms include:

Bothered by certain fabrics or clothing textures
Disliking socks with seams
Having difficulty with wearing shoes
Avoiding messy textures
Being averse to touch such as hugs and kisses

Individuals with tactile defensiveness may exhibit avoidance behaviors, such as resisting or withdrawing from touch, fidgeting, or displaying anxiety or distress in response to certain tactile sensations. It's important to note that these behaviors are not intentional but are rather a response to the discomfort associated with tactile input [3].

Understanding the causes and symptoms of tactile defensiveness is crucial in identifying and managing this sensory processing difficulty. By recognizing these indicators, individuals and caregivers can seek appropriate interventions and strategies to support individuals with tactile defensiveness in their daily lives.

Diagnosis and Evaluation

To determine if an individual is experiencing tactile defensiveness, a comprehensive evaluation is necessary. This evaluation typically involves the assessment by occupational therapists and the use of questionnaires and observations.

Assessment by Occupational Therapists

Occupational therapists (OTs) play a crucial role in the diagnosis and evaluation of tactile defensiveness. They are trained to assess sensory processing difficulties and can specifically evaluate tactile sensitivity and defensiveness. OTs use various techniques and tools to gather information about an individual's sensory responses and behaviors.

One technique used by OTs is sensory integration therapy. This therapy involves evaluating the child for sensory defensiveness and sensory cravings using a battery of tests, observations, and interviews with caregivers [4]. Additionally, OTs may utilize specific techniques such as "brushing" as part of the evaluation process. The Wilbarger protocol, for example, involves using a soft-bristled brush in a specific way to provide deep pressure, followed by joint compressions.

This technique can be particularly helpful in identifying tactile defensiveness in children [4].

Questionnaires and Observations

Questionnaires and observations are valuable tools in assessing tactile defensiveness. These methods involve gathering information from caregivers, teachers, and the individual themselves to gain insight into their sensory experiences and behaviors.

Questionnaires for sensory processing, such as Dunn's model, can help identify the individual's sensory processing patterns and responses to stimuli. These questionnaires provide valuable information about their neurological thresholds and self-regulation strategies. Caregivers and teachers can provide important observations regarding the individual's responses to different sensory events in daily life.

By combining the assessment by occupational therapists with questionnaires and observations, a comprehensive evaluation can be conducted to diagnose tactile defensiveness. This evaluation process helps in understanding the individual's sensory processing patterns, identifying specific areas of sensitivity, and tailoring the treatment approach accordingly.

It's important to note that the diagnosis of tactile defensiveness should be made by qualified professionals, such as occupational therapists, who specialize in sensory processing difficulties. The evaluation process allows for a more accurate understanding of an individual's tactile defensiveness, leading to the development of effective treatment strategies.

Treatment Approaches

When it comes to addressing tactile defensiveness, there are various treatment approaches that can help individuals manage and overcome their sensory challenges. Two commonly used approaches are sensory integration therapy and sensory diet implementation.

Sensory Integration Therapy

Sensory integration therapy is a treatment approach used by occupational therapists to help individuals with sensory processing issues, including tactile defensiveness. This therapy aims to help individuals experience an optimal level of arousal and regulation by engaging in specific movement activities and resistive body work. It also involves techniques such as brushing of the skin to provide sensory input and promote appropriate integration and responses to sensory stimuli.

The goal of sensory integration therapy is to "rewire" the brain so that individuals can better process and respond to sensory information. By engaging in sensory integration activities, individuals can become more confident, successful, and interactive in their exploration of the world around them.

This therapy is often carried out in a specialized setting equipped with sensory gym equipment, such as swings, ball pits, and weighted vests, to provide different types of sensory input and promote regulation.

Sensory Diet Implementation

Sensory diet implementation is another important aspect of managing tactile defensiveness. In this approach, caregivers work closely with occupational therapists to create a detailed schedule of tailored therapies specific to each individual. The sensory diet is designed to provide a consistent and structured routine of sensory activities throughout the day, both at home and in other settings like school.

The sensory diet may include a variety of activities that offer regulating sensory input. This can involve incorporating sensory-friendly items and adaptations into the individual's environment. For example, creating quiet spaces, reducing visual clutter, and using items like weighted blankets or fidget toys can help provide calming and regulating input. The sensory diet is personalized to meet the unique needs of each individual, taking into consideration their sensory preferences and sensitivities [4].

By combining sensory integration therapy and sensory diet implementation, individuals with tactile defensiveness can receive comprehensive support for managing their sensory challenges. These approaches aim to improve sensory processing and regulation, ultimately enhancing the individual's daily functioning and overall well-being.

It is important to work with qualified professionals, such as occupational therapists, who can provide guidance and develop personalized treatment plans based on individual needs.
