What is Sensory Integration or Sensory Processing?

 

Sensory integration is the ability to organize sensory information for use.

Sensory Integration and Adaptation 

Growing, Learning, Adapting

In a growing child, many senses must be developed in order for him to adapt and survive - senses of taste, hearing, vision, smell, proprioception (muscles and joints), touch, movement, and gravity.
As a child develops, information from these senses combines, enabling him to automatically adapt to each new environment or setting. These senses protect him from harm and help him learn about his body parts in relation to each other. Soon he can balance his head, trunk and limbs for rolling, creeping, sitting, walking, standing.
Once a child develops reflex maturation, body awareness and postural balance, he learns to control body functions and is ready for motor skills which demand more coordination. He masters riding a bike, jumping rope, skipping, catching and throwing balls, putting together puzzles, speaking, reading, writing, buttoning buttons, tying shoelaces. He learns to quiet himself when upset, interact with others and play with toys in a meaningful way. He masters his environment and gains feelings of adequacy, accomplishment, and inner self security.

Not Every Child Is So Lucky
Problems occurring pre-natally, at birth or early in life may impair a child's ability to integrate information from all of his senses. Some learning skills are blocked. One child yearns to communicate but cannot form words, even though his hearing is perfect. Another is bright-eyed but clumsy. Still another runs like a deer, swims like a fish, but cannot fix his attention on any one task for more than a few seconds. She frustrates easily, and/or breaks out in temper tantrums. She is unable to play independently. She has difficulty dressing herself. She is disorganized.
Impaired sensory integration shows up in older children too. One child is of above average intelligence and is learning in school, but has great difficulty with reading or written communication. Another has sharp vision and hearing but prints his ABC's backwards. He holds a pencil awkwardly. Left and right confuse him. Among other children, he soon begins to feel inadequate; he develops a poor self-image, becomes destructive, refuses to keep trying, becomes disruptive and aggressive, cannot adapt to group settings.
Why does this happen? What can be done to develop the missing skills? Is it too late?

Parent, Teacher, Clinician
Often, sensory integration can be improved with appropriate treatment. Occupational therapists skilled in this approach can help a child more fully realize his potential by building a better foundation for skills to develop and/or compensate for deficits.
The therapist also works to help parents and teachers understand these limitations which are most significant to the child's daily performance. With a sound treatment program, a child can be helped through trying times to overcome physical and emotional challenges, to adjust socially, and to fit more comfortably into her environment.
It takes a coordinated effort, however. Parents, teachers and doctors play a key role; they must understand and accept the goals and methods of treatment. Parents, especially, must relate closely with the child and share his joy of accomplishment when he develops new abilities. Teachers must be aware of how much performance to expect in school... when discipline is needed and when it is harmful, and how to motivate a child using his most effectively developed skills. The family doctor, psychologist or neurologist must realize to what extent a child is hampered by sensory integrative dysfunction in order to prescribe accurate, effective medical treatment. Later in life, an employer may need to know a young person's special needs as well as his special skills, so he can work productively with satisfaction and fulfillment.

The Role of O.T. For Sensory Integrative Dysfunction
What's Wrong?
Before treating a child, we must find out exactly what her problems are. Tests have been devised to evaluate a child's strengths and weaknesses. They must be given by an occupational therapist who has advanced training with these tests. The therapist must evaluate the child and interpret the results to learn the source of her problems. Home and school information is critical in understanding the child and determining needs. Typical problems include:
A. The child may have difficulty with:
  • Learning new motor skills
  • Organization
  • Handwriting
  • Keeping his/her balance
  • Puzzles

  • Tying shoes and other self care skills
  • Following instructions
  • Language skills
  • Eating a variety of foods
B. The child may:
  • Overreact to a touch or sound
  • Reject certain food textures
  • Be aggressive or withdraw in play situations
  • Be easily distracted
  • Be fearful of certain movement experiences
  • Have difficulty with transition
  • Avoid playing on stomach, preferring to sit/stand
  • Avoid drawing, cutting, coloring
C. The child may seem:
  • Clumsy
  • Lazy
  • Manipulative

 

What Can Be Done?
Occupational therapy for sensory integrative dysfunction begins with understanding the problem. After evaluation, the therapist explains to the parents aspects of sensory-motor functions that are problems. This determines what kinds of intervention might be indicated. The therapist also suggests what attitudes and expectations may best aid the child's progress, since it sometimes takes many months to show the effects of treatment. Discussion with teachers and other professionals may be indicated.
The treatment environment, engineered by the therapist, utilizes equipment and space designed to activate or modulate sensory-motor experiences, depending on the child's needs. There is no "typical" case. Each child is unique. The therapist monitors and interacts with the child and the environment to facilitate play that will meet the child's needs. Some methods include:
  • Touch and movement experiences
  • Active or controlled movement
  • Heavy muscle work
  • Gross motor activities using both or one side of the body
  • Activities requiring balance and adjustment of posture

  • Calming techniques
  • Fine motor or visual perceptual activities
  • Interactive or turn taking activities
  • Techniques to address food aversion


How Does A Child Respond?
Responses depend on the child's combination of difficulties. Here is an assortment of commonly observed responses that may show up early in treatment:
  • Improved organization
  • Faster responses to auditory or visual stimuli
  • Improved balance and comfort with movement experiences
  • Initiation of play
  • Better coordination of both sides of the body
  • Refined motor skills in hand and body movements

  • Willingness to try new activities or tasks
  • Less aversion to touch
  • Decreased hyperactivity
  • Longer attention span
  • Better peer relationships
  • Improved self esteem
  • Increased vocalization

Often, the benefits from occupational therapy using sensory integrative procedures are not immediate. Significant improvements may take time to develop. Some children respond to therapy better than others. But when parents, teachers, therapists, and other disciplines coordinate efforts in treating a child, some major improvements are almost always achieved.
Most importantly, the improvements though this sensory integrative approach continue to benefit the child during his adult life.
Children do not outgrow sensory integrative dysfunction. They may develop compensatory strategies for specific problems. This need to compensate for underlying deficits, however, can take its toll on the person. Stress and anxiety, poor interpersonal skills, low self esteem an/or poor work habits are frequently seen in adult clients. Evaluation, detailed history and current concerns are critical components of identifying sensory integrative dysfunction in adults. Intervention includes individual therapy and support to change life patterns including a "sensory diet" to promote improved integration and more effective compensation. A support group may also be helpful for adults/adolescents to help deal with life issues.
