Another day, another disorder

In chatting with Quinn's post-surgery physical therapist yesterday, she mentioned something called proprioception and said he may have some challenges feeling where his body fits into the space around him, as in how to climb a ladder, how hard to push with a pencil, how rough to play with the dog (a current BIG issue in our house, as our poor new dog Rosie will tell you...).

I went home and Googled it and found a textbook description of my son as a sensory-seeking kid who is under-responsive to touch and movement. A few of the characteristics are off, but if you read the list below you'll pretty much know Quinn - it's astonishingly, eerily accurate.

I'm encouraged to know there might be a cause for his behavior besides cruelty to animals - which really didn't seem right to me because he LOVES Rosie but can't seem to help himself from being too rough with her. Still, it makes me nervous that I've never heard of this before. Is it real? Quackery? Something in between? If anyone knows about this or has any insights, I'd really appreciate hearing from you, either here or at jspitz@azstarnet.com

And if you haven't heard of this, either, here's what I learned in a quick Google search. First a general definition and then a definition of Quinn's apparent end of the beach along with those checklists that seem to be written just about him:

Proprioceptive dysfunction refers to a body’s inability to properly process sensory input related to proprioception. The sense of proprioception differs from the other senses of sight, smell, sound, taste, and touch by involving more internal sensory perception by which we receive the pain and movement of the internal organs⁽¹⁾.

Sensory Seeking children have nervous systems that do not always process that sensory input is "coming in" to the brain. They are under-responsive to sensation. As a result, they seek out more intense or longer duration sensory experiences. Some behaviors that can be observed are: Hyper-activity as they seek more and more movement input; Unawareness of touch or pain, or touching others too often or too hard (may seem aggressive); Engaging in unsafe behaviors, such as climbing too high; Enjoying sounds that are too loud, such as TV or radio volume.

If they are under responsive to proprioceptive input (i.e. sensory seeking) they will...

walk to hard, push too hard, bang too hard write too hard, play with objects too hard, etc.

be the loud ones, rough ones, crashers, movers, shakers, runners, jumpers, and bouncers (i.e. an insatiable bundle of energy!)

shake his legs or constantly bang the back of his foot on the floor/chair while sitting in class

play too rough (often hurting himself or others), jump off of or crash into ANYTHING he can

crack his knuckles, chew on his fingers, bite his nails until they bleed, chew on pens, gum, pencils, clothing collars, sleeves, or strings, or inedible objects (i.e. paper clips, pieces of toys etc.)

enjoys TIGHT clothes (i.e. turtlenecks, tight belts, hoods, hats, jackets zipped ALL the way up, tight pajamas etc.) (This is the ONLY item on this list that doesn't describe Quinn!)
