This change in the weather, season can create enough of sensory 'triggers' that I thought I would share again, some great information about SPD -sensory processing disorder. I just copied a portion of the article, with some key points to remember , please click on the link to see the whole piece.
Children, teens and adults with SPD experience either over-sensitivity (hypersensitivity) or under-sensitivity (hyposensitivity) to an impairing or overwhelming degree. The theory behind SPD is based on the work of occupational therapist Dr. A. Jean Ayres. In the 1970s, Dr. Ayres introduced the idea that certain people's brains can't do what most people take for granted: process all the information coming in through seven—not the traditional five—senses to provide a clear picture of what's happening both internally and externally.
Along with touch, hearing, taste, smell and sight, Dr. Ayres added the "internal" senses of body awareness (proprioception) and movement (vestibular). When the brain can't synthesize all this information coming in simultaneously, "It's like a traffic jam in your head," Peske says, "with conflicting signals quickly coming from all directions, so that you don't know how to make sense of it all."
What are these two "extra" senses in Dr. Ayres' work?
Proprioceptive receptors are located in the joints and ligaments, allowing for motor control and posture. The proprioceptive system tells the brain where the body is in relation to other objects and how to move. Those who are hyposensitive crave input; they love jumping, bumping and crashing activities, as well as deep pressure such as that provided by tight bear hugs. If they're hypersensitive, they have difficulty understanding where their body is in relation to other objects and may bump into things and appear clumsy; because they have trouble sensing the amount of force they're applying, they may rip the paper when erasing, pinch too hard or slam objects down.
The vestibular receptors, located in the inner ear; tell the brain where the body is in space by providing the information related to movement and head position. These are key elements of balance and coordination, among other things. Those with hyposensitivity are in constant motion; crave fast, spinning and/or intense movement, and love being tossed in the air and jumping on furniture and trampolines. Those who are hypersensitive may be fearful of activities that require good balance, including climbing on playground equipment, riding a bike, or balancing on one foot, especially with eyes closed. They, too, may appear clumsy.
To help parents determine if their child's behavior indicates possible SPD, Peske and Biel have created a detailed sensory checklist that covers responses to all types of input, from walking barefoot to smelling objects that aren't food, as well as questions involving fine and gross motor function, such as using scissors (fine) and catching a ball (gross). The SPD Foundation also offers a litany of "red flags." The list for infants and toddlers includes a resistance to cuddling, to the point of arching away when held, which may be attributed to feeling actual pain when being touched. By preschool, over-stimulated children's anxiety may lead to frequent or long temper tantrums. Grade-schoolers who are hyposensitive may display "negative behaviors" including what looks like hyperactivity, when in fact they're seeking input.
