low or no sense of proprioception, aka the ability to to have a sense of body position, force, and movement. it can show up as-

not knowing where your limbs are without looking at them

being unaware of involuntary movements (I didn’t realize I physically stimmed until people started mentioning it to me)

having a poor sense of balance

difficulty controlling how soft/hard you hit

having a hard time with physically complex tasks

textbook clumsiness

slow reflexes (could also be a processing issue, I have both)

being unaware of your posture until it’s mentioned

having difficulty with uneven surfaces

issues specifically when walking up or down stairs

people would be like “hey you do this really weird thing with your hands what’s that about 🤨”

and I’d be like. “??? I don’t think I do. I think I would know if I was doing a funky little thing with my hands, me being myself” and then I didn’t.
