All children learn about the world through their senses. A common symptom of Pervasive Developmental Disorder and autism is an unusual response to the senses of hearing, sight, touch, smell and/or movement. According to the National Information Center for Children and Youth with Disabilities, children with pervasive developmental disorders "may seem underresponsive or overresponsive to sensory stimuli. Thus, they may be suspected of being deaf or visually impaired. It is common for such young children to be referred for hearing and vision tests. Some children avoid gentle physical contact, yet react with pleasure to rough-and-tumble games. Some children carry food preferences to extremes, with favored foods eaten to excess. Some children limit their diet to a small selection."
Is your child super sensitive to certain noises, bright lights or crowds? Does he look out of the corners of his eyes? Is he afraid of swings or very clumsy? Does he dislike being touched or hugged unless he initiates it? Is he extremely irritated by tags or seams on his clothes? Does he refuse to wear a coat and fuss over socks and shoes? Does he have an unusually high or low tolerance for pain?
These may be signs of Sensory Processing Disorder, also known as Sensory Integration Dysfunction. Sensory processing problems are fairly common among children with autism, PDD and Asperger's Syndrome. Please be aware that sensory problems alone do not mean a child has autism. Some children have a sensory processing disorder only, but no other diagnosis.
The theory of sensory integration was developed by occupational therapist A. Jean Ayres, Ph.D. Sensory integration occurs when our brains organize the information from our senses for our use. For some people, sensory integration does not develop as it should. Sounds and sights may seem stronger, more chaotic and more distracting or disorienting than they do to other people. People with sensory integration dysfunction may have trouble with balance and coordination. Occupational and physical therapists who are also trained in sensory integration techniques offer a range of activities designed to help the child process the information he receives from his senses in a more typical manner.
An occupational therapist (OT) can develop a treatment plan for a child that a parent can also follow at home. The child may need to play with different textures (such as sand, play-dough or shaving cream), to swing, or to sit atop a large ball. The activities should be just challenging enough to help the child respond better to sensory information without being overwhelmed.
"Traditional sensory integrative therapy takes place on a 1:1 basis in a room with suspended equipment for varying movement and sensory experiences," according to Marie DiMatties and Jennifer Sammons at The Council for Exceptional Children. "The goal of therapy is not to teach skills, but to follow the child's lead and artfully select and modify activities according to the child's responses."
"The How Does Your Engine Run? Program is a step-by-step method that teaches children simple changes to their daily routine, such as a brisk walk, jumping on a trampoline before doing their homework, and listening to calming music, that will help them self-regulate or keep their engine running 'just right.' Through the use of charts, worksheets, and activities, the child is guided in improving awareness and using self-regulation strategies," according to DiMatties and Sammons.
Children with autism, PDD and Asperger's Syndrome may receive free physical and occupational therapy at their public schools or through their state's early intervention program. Parents can ask their school system to evaluate their child to see if he qualifies for these services, including sensory integration activities.
An occupational therapist will work with the child to improve his sensory motor skills in addition to fine motor skills (holding a pencil, using scissors) and self-help skills (using buttons, zippers and silverware). A physical therapist can work on gross motor skills such as walking, running, balance and climbing. Also, parents and caregivers can learn sensory-rich activities to do at home with the child. This therapy is almost never offered as a sole treatment for autism or PDD; instead, it may be a piece of a larger program.
Some studies show people benefit from Sensory Integration Therapy while other studies do not show a benefit. A small study released in 2008 by Temple University researchers found that children with autism spectrum disorders who had sensory integration therapy had fewer "autistic mannerisms" than children who received fine motor therapy.
Sensory integration treatment can be expensive if not covered by medical insurance or provided by the school or early intervention office.
Remember, a child's "occupation" is play and learning about his world.

Thank you for sharing the article. I actually have sensory integration dysfuntion without autism and never received any therapy up until now. I am just starting therapy with an occupational therapist who works with both adults and children. My daughter benefited immensely over the last year from therapy and she is starting to overcome a lot of things I as an adult have difficulty with. I tried the brushing and compression techniques on myself but no results. I am finding out that sensory integration therapy will work on adults, but it takes a lot longer to see benefits and some of the things may not work at all whereas different things might. I'm in my 30s, so I guess my brain is pretty established. Oh well. I figured out how to get along fine on my own, but I am going through this stuff with my daughter (hence the OT who works with both adults and children). The OT is showing me coping mechanisms as well. Plus she's encouraged me to take up swimming for both myself and my daughter. Swimming evidently is immensely wonderful for the senses and helps you be more organized and stuff. I am finding it's helping my ADD a little bit after I've swum for 30 minutes. Thank you YMCA heated swimming pool. I think it also is helping my daughter immensely as well.
But my daughter has done amazingly over the last year with sensory integration therapy. When she was 24 months old, she didn't respond to her name or any language, she flapped her hands constantly, walked on her toes, never looked anyone in the eye. I could go on. Within a week of brushing and compression techniques done every 2 hours, she was starting to make more eye contact. Over the next couple months she started responding to language and her name. Then gradually she stopped flapping her arms and only does so when she's like really upset or really excited. She no longer walks on her toes, though she occasionally walks around on her heels which I find stranger. But, anyways, many of the autistic "red flags" started lessening with sensory integration therapy, with the brushing and compressions and massages. Plus other exercises on balls and bouncing and sensory stimulation. She still has some of these things, again when she's upset, tired, or out of her regular routine. The sensory therapy hasn't really done much for her rigidity to routine and rituals. I know some would say some of this would just gradually go away as she got older and had other types of therapy, but I think it sped this along it's course. And if you compare her to me... I really wish I had sensory integration therapy when I was a child. Maybe some of these things in me would have gone away too. *sigh*
If you can't find empirical evidence I would suggest getting in touch with the professional body for Occupational Therapists and they should be able to put you in the right area. I also believe that prior to Ayres someone called Delacatto was also working in the same area as is Olga Bogdashina today.
