Sensory integration is the ability to take in information through the senses of touch, movement, smell, taste, vision, and hearing, and to combine the resulting perceptions with prior information, memories, and knowledge already stored in the brain, in order to derive coherent meaning from processing the stimuli. The mid-brain and brainstem regions of the central nervous system are early centers in the processing pathway for sensory integration. These brain regions are involved in processes including coordination, attention, arousal, and autonomic function. After sensory information passes through these centers, it is then routed to brain regions responsible for emotions, memory, and higher level cognitive functions.
Sensory Integration Dysfunction (SID, also called
sensory processing disorder) is a neurological disorder causing difficulties
with
processing information from the five classic
senses (vision,
auditory,
touch,
olfaction, and
taste), the sense of movement (vestibular
system), and/or the positional sense (proprioception). For those with SID,
sensory information is
sensed normally, but
perceived abnormally. This is not the same as
blindness or
deafness, because, unlike those disorders,
sensory information is sensed by people with SID, but the information tends to
be analyzed by the brain in an unusual way that may cause pain or confusion.
SID can be a disorder on its own, but it can also be a characteristic of other
neurological conditions, including autism spectrum disorders, dyslexia,
Developmental Dyspraxia, Tourette's Syndrome, multiple sclerosis, and
speech delays, among many others. Unlike many
other neurological problems that require validation by a licensed psychiatrist
or physician, this condition is most often diagnosed by an occupational
therapist.
Treatment
The main form of sensory integration therapy is a type of occupational therapy that places a patient in a room specifically designed to stimulate and challenge all of the senses. During the session, the therapist works closely with the patient to provide a level of sensory stimulation that the patient can cope with, and encourage movement within the room. Sensory integration therapy is driven by four main principles:
Just Right Challenge (the patient must be able to successfully meet the challenges that are presented through activities)
Adaptive Response (the patient adapts his behavior with new and useful strategies in response to the challenges presented)
Active Engagement (the patient will want to participate because the activities are fun)
Patient Directed (the patient's preferences are used to initiate therapeutic experiences within the session).
People
with lower sensitivity (hyposensitivity) may be exposed to strong sensations
such as stroking with a brush, vibrations or rubbing. Play may involve a range
of materials to stimulate the senses such as play dough or finger painting.
people with heightened sensitivity (hypersensitivity) may be exposed to peaceful
activities including quiet music and gentle rocking in a softly lit room. Treats
and rewards may be used to encourage people to tolerate activities they would
normally.
Looking at Sensory Integration disorders and inhibiting them:
Adaptive equipment and assistive devices comes in all shapes and forms and can be very specialized. Below are sensory areas that may be impaired and examples of assistive devices or adaptive equipment that can inhibit dysfunction. Each is listed under specific sensory areas. Also, various forms of sensory dysfunctions and their indications are included in the charts below.
Tactile Sensation
Consumers with deficits in this area can have the following reactions to stimuli. If any of the following are noted from staff, caretakers/family, or house staff, the consumer’s time in the area can be lengthened or decreased as per his/her tolerance and specific objectives.
TACTILE SENSE: input from the skin receptors about touch, pressure, temperature, pain, and movement of the hairs on the skin.
SIGNS OF TACTILE DYSFUNCTION:
|
HYPERSENSITIVITY TO TOUCH (tactile defensiveness): __ becomes fearful, anxious or aggressive with light or unexpected touch __ distressed when diaper is being, or needs to be, changed __ becomes frightened when touched from behind or by someone/something they can not see (such as under a blanket) __ complains about having hair brushed __ avoids/dislikes/aversive to "messy play", i.e., sand, mud, water, glue, glitter, playdoh, slime, shaving cream/funny foam etc. __ resists friendly or affectionate touch from anyone besides parents or siblings (and sometimes them too!) __ a raindrop, water from the shower, or wind blowing on the skin may feel like torture and produce adverse and avoidance reactions
|
HYPOSENSITIVITY TO TOUCH (under-responsive): __ may crave touch, needs to touch everything and everyone __ is not aware of being touched/bumped unless done with extreme force or intensity __ is not bothered by injuries, like cuts and bruises, and shows no distress with shots (may even say they love getting shots!) __ may not be aware that hands or face are dirty or feel his/her nose running __ may be self-abusive; pinching, biting, or banging his own head __ mouths objects excessively __ frequently hurts other people or pets while playing __ repeatedly touches surfaces or objects that are soothing (i.e., blanket) __ seeks out textures that provide strong tactile feedback |
POOR TACTILE PERCEPTION AND DISCRIMINATION: __ has difficulty with fine motor tasks such as buttoning, zipping, and fastening clothes __ may not be able to identify which part of their body was touched if they were not looking __ may be a messy dresser; looks disheveled, does not notice pants are twisted, shirt is half untucked, shoes are untied, one pant leg is up and one is down, etc. __ has difficulty using scissors, crayons, or silverware __ continues to mouth objects to explore them even after age two __ has difficulty figuring out physical characteristics of objects; shape, size, texture, temperature, weight, etc. __ may not be able to identify objects by feel, uses vision to help; such as, reaching into backpack or desk to retrieve an item
