Sensory Processing Disorder

Sensory processing disorder (SPD) is the inability to use information received through the senses in order to function smoothly in daily life.  SPD is not one specific disorder but rather an umbrella term to cover a variety of neurological disabilities. Sensory processing disorder is also called Sensory Integration Dysfunction (SI Dysfunction) and Dysfunction in Sensory Integration (DSI).  SPD happens in the central nervous system, at the “head” of which is the brain.  When processing is disorderly, the brain cannot do its most important job of organizing sensory messages.  The child cannot respond to sensory information to behave in a meaningful, consistent way. He may also have difficulty using sensory information to plan and carry out actions that he needs to do. Thus he may not learn easily. The following infograpic, courtesy of summarises many of the more common signs of Sensory Processing Disorder.

The most common category of SPD is Sensory Modulation Disorder. This is suspected when the child exhibits one or more symptoms with frequency, intensity and duration.

This chart provides a quick overview of common problems.

Table depicting Sensory Modulation Problems



Another category of SPD is Sensory Discrimination Disorder, which is the difficulty in distinguishing one sensation from another, or in understanding what a sensation means.

The third category of SPD is Sensory-Based Motor Disorder, which includes two types, Postural Disorder involving problems with movement patterns, balancing and using sides of the body together (bilateral coordination) and Dyspraxia whereby the child has problems performing coordinated and voluntary actions.

The vestibular system tells us about up and down and whether we are upright or not.  It tells us where our heads and bodies are in relation to the earth’s surface.  It sends sensory messages about balance and movement from the neck, eyes and body to the central nervous system for processing and then helps generate muscle tone so we can move smoothly and efficiently. It tells us about whether we are moving or standing still and whether objects are moving or motionless in relation to our body in addition to informing us what direction we are going in and how fast.  The vestibular system gives us information necessary for many everyday skills such as gravitational security, movement and balance, muscle tone, bilateral co-ordination, motor planning, vision and hearing and emotional security.


The over-responsive child who shows intolerance for movement may:

  • Dislike playground activities such as swinging, spinning and sliding.
  • Be cautious, slow moving, and sedentary, hesitating to take risks.
  • Seem willful and uncooperative.
  • Be very uncomfortable in lifts and on escalators.
  • Demand continual physical support from a trusted adult

The child with gravitational insecurity may:

  • Have a great fear of falling, even where no real danger exists.
  • Be fearful of heights, even slightly raised surfaces.
  • Become anxious when her feet leave the ground, feeling that even the smallest movement will throw her into outer space.

  • Be fearful when someone moves her .
  • For self-protection, try to manipulate her environment or other people.
  • Have poor proprioception and poor visual discrimination

The sensory disregarder with under-responsiveness to vestibular sensations may:

  • Not notice or object to being moved.
  • Seem to lace inner drive to move actively.
  • Once started, swing for a lengthy time without getting dizzy.
  • Not notice sensation of falling and may not respond efficiently to protect himself by extending his hands or a foot to catch himself

The sensory-seeking child with increased tolerance for movement may:

  • Need to keep movement, as much as possible, in order to function.
  • The child may have trouble sitting still or staying in a seat.
  • Repeatedly, vigorously shake her head, rock back and forth and jump up and down.
  • Crave intense movement experiences, such as bounding on furniture, using a rocking chair, turning in a swivel chair or assuming upside-down positions.
  • Be a thrill seeker, enjoying fast-moving or spinning playground equipment or seeking the fast and scary rides at an amusement park.
  • Not get dizzy, even after twirling or spinning rapidly for a lengthy amount of time.
  • Enjoy swinging very high or for long periods of time.
  • Like seesaws or trampolines.

The sensory child with sensory-based postural disorder affection movement of the head, balance, muscle tone and bilateral coordination may:

  • Lose her balance unless both feet are firmly planted, as when stretching on tiptoes or standing on both feet when her eyes are closed.
  • Easily lose her balance when out of a two-footed position, e.g climbing stairs, riding a bicycle, hopping or standing on one foot.
  • Move in an uncoordinated, awkward way.

  • Fatigue easily during physical activities.
  • Be unable to catch herself from falling.
  • Not have crawled as a baby.
  • Have poor body awareness.
  • Have poor gross motor skills and frequently stumble and trip.
  • Be clumsy at sports or active games.
  • Have poor fine motor skills and difficulty using pencils, crayons or combs.
  • Have difficulty making both feet or both hands work together such as jumping up and down or throwing and catching a ball.
  • Have difficulty using one foot of hand to assist the other during tasks e.g standing on one foot to kick a ball.
  • Have trouble using both hands in a smooth, alternating manner.
  • Not have an established hand preference by the age or four or five.

  • Have a hard time with organization and structured activities.

The sensory child with dyspraxia or poor motor planning may:

  • Have difficulty conceptualizing, organizing and carrying out a sequence of unfamiliar movements.
  • Be unable to generalize what she has already learned in order to accomplish a new task.

The child who is emotionally insecure may:

  • Get easily frustrated and give up quickly.
  • Be reluctant to try new activities.
  • Have a low tolerance for potentially stressful situations.
  • Have low self esteem.
  • Be irritable in others company and avoid or withdraw from people.
  • Have difficulty making friends or relating to peers.



Proprioception tells us about our own movement and body position. Proprioception informs us:

  • Where our body or body parts are in space.
  • How our body parts relate to one another.
  • How much and how quickly our muscles are stretching.
  • How fast our body is moving through space.
  • How our timing is.
  • How much force our muscles put forth.

Proprioception dysfunction is the inefficient processing of sensations perceived through the muscles and skin, as well as the joints.  The child with poor proprioception has difficulty interpreting sensations about the position and movement of his body parts. He may show confusion when walking down a street, getting in and out of the bath or crossing the playground. He may be clumsy and easily frustrated. He may exert too much pressure or too little pressure on objects, struggling to turn door knobs and regularly breaking toys and pencils. He may have a poor grip on forks or combs and experience difficulty zipping a jacket, buttoning a shirt or getting out of bed in the dark.


The child who is over-responsive to proprioceptive input may:

  • Prefer not to move.
  • Become upset when limbs are passively moved.
  • Become upset when it is necessary to stretch or contract his muscles.
  • Avoid weight-bearing activities such as jumping, hopping, running, crawling or rolling.
  • Be a picky eater

The under-responsive child may:

  • Have low tone.
  • Fix elbow to ribs when writing, or knees tightly together when standing to compensate for low muscle tone.
  • Break toys easily.

The sensory seeking child may:

  • Deliberately bump and crash into objects in the environment.
  • Stamp or slap his feet on ground with walking.
  • Kick his heels against the floor ro chair.

  • Appear to be aggressive

The child with poor discrimination and dyspraxia may:

  • Have poor body awareness and motor control.
  • Have difficulty planning and executing movement.
  • Have difficulty positioning his body when someone is helping him into his coat or when he is trying to dress or undress.
  • Have difficulty knowing where his body is in relation to objects and people frequently falling, tripping or bumping into obstacles.
  • Show fear when moving in space.

The child with emotional insecurity may:

  • Avoid participation in ordinary movement experiences because they make him feel uncomfortable or inadequate.
  • Become rigid, sticking to the activities that he has mastered and resisting new physical challenges.
  • Lack self-confidence.
  • Become timid in unfamiliar situation.



Children with visual sense dysfunction are inefficient in coordinating visual discrimination and visual-motor skills with vestibular, proprioceptive and postural mechanisms eg. Their eyes and bodies are out of syn. When dysfunction involves movement (ie tripping on air), posture (slumping at the desk) and body awareness (difficulty learning left and right) it is likely that the problem is sensory based.


The child with a problem with basic visual skills may:

  • Have headaches, eye strain, or red, burning, itchy or teary eyes.
  • Rub eyes or blink, frown and squint excessively.
  • Complain about blurred images when looking at pictures, print or faces.

The vestibular and auditory systems work together as they process sensations of movement and sound. Hearing is the ability to receive sound and this basic skill develops in the womb. The ear’s influence on physical development is profound as it is vital not only for hearing, balance and flexibility but also for bilateral coordination, respiration, speaking, self-esteem, social relationships, vision and academic learning.


The child with difficulty modulating auditory sensations may:

  • Be distressed by loud noises, including the sound of voices.
  • Be distressed by sudden noises, such as thunder, fire alarms, sirens and balloons popping.
  • Be distressed by tinny or metallic sounds.
  • Be distressed by high-pitched sounds such as whistles, violins and sopranos.
  • Be distressed by sounds that do not bother others such as a toilet flushing, a distant church bell or soft background music.

The child with poor auditory discrimination may:

  • Seem unaware of the source of sounds or may look all around to locate where they come from.
  • Have difficulty recognizing particular sounds, such as voices or cars coming down the street.
  • Have difficulty tracking a sound in the environment, such as footsteps.
  • Have difficulty recalling, repeating or referring to words, phrases, conversations, song lyrics or instructions both right away or later.
  • Be unable to focus or maintain attention to a voice, conversation, story or sound without being distracted by other sounds.
  • Have difficulty hearing or reading jokes, verbal math problems, crossword puzzle definitions or discussions and understanding how all the information fits together into a coherent whole.
  • Have a poor sense of timing and rhythm when clapping, marching, singing, jumping rope or playing band instruments.

The child with receptive language difficulty may:

  • Have a problem discriminating similar sounding word sounds, especially consonants at ends of words, as in cap/cat, bad/bag, side/sign.
  • Have a short attention span for listening to stories or for reading.
  • Misinterpret questions and requests.
  • Be able to follow only one or two instructions in sequence.
  • Look to others before responding.

The child with speech and articulation difficulty may:

  • Be unable to speak clearly enough to be understand.
  • Have a flat, monotonous voice quality.
  • Speak very loudly or very softly.
  • Speak with a hoarse, husky, strident, weak, or breathy voice.
  • Speak hesitantly or without fluency and rhythm.



What should you do and where should you start?

  1. You can take the “wait and see” approach and wait to see if the dysfunction improves over time.
  2. You can improve your child’s “sensory diet” by liaising with your child’s teacher to develop a home and school sensory program that will help strengthen your child’s skills.
  3. Seek specialist evaluation to screen your child for possible risk factors or do a full Sensory Profile evaluation.



After an evaluation has taken place, the next step is to arrange for treatment. The most beneficial treatment for SPD is occupational therapy using a sensory integration framework. The Occupational Therapist improves the person’s social participation, self-esteem, self-regulation and sensory-motor abilities. The following is a sample of the activities that an OT may provide:

  • To reduce tactile defensiveness.
  • To improve tactile discrimination.
  • To develop better body awareness and improve postural security.
  • To improve balance.
  • To improve bilateral coordination.
  • To improve motor planning.
  • To improve fine motor skills.
  • To improve extension against the pull of gravity.
  • To improve flexion.
