Sensory integration disorders in children - how to recognize them and when to seek help?

Symptoms of sensory disorders in children can be varied and not always immediately obvious. Sometimes there are difficulties concentrating, other times over-sensitivity to sounds, textures or motor stimuli. Sometimes a child has problems with balance, eating or reacts violently to situations that are neutral to peers. All this may indicate a sensory integration disorder, that is, an abnormal way in which the nervous system processes stimuli. Early recognition of such difficulties and appropriate therapy make it possible to support the child's development, improve daily functioning and reduce the frustration associated with an excess or deficiency of sensory impressions.

SI disorders - what are they?

SI disorders - what exactly is it? Sensory integration disorder (colloquially known as "SI disorder," or Sensory Integration / Sensory Processing Disorders) is an increasingly recognized developmental problem in children. Symptoms of a sensory disorder can be subtle or pronounced - from eating and sleep problems in infants to difficulties with concentration, coordination and behavior in older children. Early recognition and proper support improve a child's chances of functioning better at home, preschool and school.

In neurophysiological terms, sensory integration disorders are difficulties in receiving, segregating and responding adequately to information coming from the senses (touch, proprioception - deep sensation, vestibular/balance, vision, hearing, taste, smell and interoception - internal sensations). As a result, a child either "overloaded" with excess stimuli reacts with anxiety, pain or rejection of contact, or is "under-stimulated" and seeks intense motor or tactile sensations. Such an inadequate nervous system response impedes motor, emotional and cognitive development.

What do sensory disorders look like in children?

The symptoms described in the literature and clinical practice are collected below. One symptom of a sensory disorder in children does not necessarily indicate the development of problems - what is important is a holistic assessment and the impact of the symptoms on the child's daily functioning.

• Tactile hypersensitivity: the child does not tolerate certain fabrics, cuts himself when touched, rejects certain foods with texture.
• Hypersensitive hearing: avoids noise, gets frightened easily, reacts by crying to sudden sounds.
• Over/underreaction to pain and temperature.
• Difficulties with balance and coordination - frequent stumbling, falls, clumsy movements.
• Problems with planning movements (e.g., difficulties in learning to tie shoelaces, drawing, writing).
• Motor overactivity or, on the contrary, apathy, low activity levels.
• Sleep disorders, difficulty falling asleep.
• Problems with concentration and emotion regulation (tantrums, getting frustrated easily).
• Difficulty in eating and accepting new tastes, textures.

The more areas affected and the stronger the impact on daily life (playing, eating, independence, learning), the more urgent the need for diagnosis.

How is sensory integration disorder diagnosed?

Diagnosis is based on three pillars: a detailed developmental interview and observation, standardized questionnaires, and functional testing by a qualified SI/occupational therapist. In practice, tools such as the Sensory Profile (parent/teacher questionnaires) and specialized clinical tests are used - and their interpretation requires clinical experience. Diagnosis should be supplemented by a physician/pedagogue/psychologist to rule out other causes (e.g., visual or hearing impairment, cognitive disorders, motor disorders).

When to seek help? - practical signals for parents and caregivers

Seek specialized evaluation if:

• you notice in your child a set of symptoms from different areas (touch, movement, hearing, emotions) lasting ≥ 3 months and affecting daily functioning;
• problems make it difficult to eat, dress, self-care, sleep, play with peers or learn;
• the child has been repeatedly diagnosed at various counseling centers without a satisfactory explanation of the difficulties;
• Symptoms worsened after vaccinated injuries, infections or environmental changes.

Early consultation (pediatrician → rehabilitation specialist/occupational therapist/psychologist) makes it possible to implement help more quickly, reduce secondary developmental difficulties, and to some extent reduce the symptoms of sensory disorders.

Therapy - what helps?

When it comes to the health of little ones, it is important not only to ask the question, SI disorder - what exactly is it, or what are the symptoms of a sensory disorder, but also how to treat the individual. The most common and well-established approach is individually tailored sensory integration therapy conducted by a trained therapist. The therapy is play-based and relies on controlled sensory stimulation (swinging, jumping, deep presses, balance tasks, etc.) to "train" the brain to correctly receive and organize stimuli. In practice, SI therapy is often implemented as part of a process such as occupational therapy for children-hencethe importance of having a certified and experienced specialist as the instructor.

It is also worth noting the scientific evidence: systematic reviews and controlled studies indicate that sensory integration therapy (especially the Ayres model approach) can be beneficial in achieving individual goals in children (e.g., improving motor skills, behavioral regulation), especially in certain groups (e.g., children with autism). At the same time, for the development of symptoms of sensory integration disorder, the literature emphasizes the need for therapy provided by qualified therapists and the selection of outcomes assessed with appropriate tools.

In practice, help tends to be multidisciplinary: SI/occupational therapy, speech therapy, physiotherapy, psychological and educational support - arranged according to the child's needs. In the therapy of daily difficulties, it is worth considering the offer of specialists who consciously conduct sessions focused on the functions of daily life.

Practical tips for parents - what to do here and now?

• Note specific situations in which the symptoms manifest themselves (when, what exactly, how long, what reaction).
• Consult your pediatrician - he will refer you to the appropriate tests and specialists.
• Avoid immediately labeling behavior; instead, look for patterns and influences on the child's functioning.
• At home, simplify stimuli (e.g., a quiet place to study, soft clothes, a predictable routine) and introduce safe proprioceptive activities (e.g., carrying a backpack with a weight, pushing/pulling safe objects together) after consulting with a specialist.
• Choose therapists with the right qualifications and ask for a therapeutic plan with measurable goals.

Summary - sensory integration disorders

Sensory integration disorder is a stimulus processing disorder that can significantly affect a child's development and daily functioning. Problems with stimulus tolerance, coordination, emotion regulation and independence are characteristic. If symptoms persist, or if they affect eating, sleep, learning or peer relationships, it is worth consulting a pediatrician and specialists (SI/occupational therapist, psychologist, speech therapist) as soon as possible. Sensory integration therapy provided by a qualified therapist, often as part of occupational therapy, is beneficial, especially when individually tailored and based on functional goals.
