passthepotatoes,

My son has low tone as part of his issues, and he could never stay still. He's still fidgety. And he talks, hums and sings almost constantly, even if no one else is listening - and he's 14. His OT explained some the constant motion as being partly a retained reflex issue (movements constantly being reflexively triggered) and as attempts to maintain proprioceptive input, so he would know here his body was in space. The constant movement improved somewhat as a consequence of the reflex integration techniques she used with him, and what remains gets better when we do deep pressure and massage a few times a day for him. Nothing but reading a sufficiently absorbing book or playing video games that are at the limit of his capacity will make him quiet, though.
