Thanks for all the info. When DS was 6 he was diagnosed w/ Developmental Coordination Disorder. On the BOT in the past (a few years ago) he has had problems with bilateral coordination. Now, he is at an 8 year old level for coordination (possibly because he works on certain skills like jumping jacks in DAPE at school), so not that far behind, but at a 5 year old level for muscle strength, running speed, and balance. He possibly has a chiari I malformation, the measurements were borderline when he had a MRI a few years ago. I just want to make sure I'm not missing something important. He isn't having Chiari headaches. He had a TBI at age 5 1/2 (his skull was fractured by his right ear). He seems unusually weak, cannot do a push up at all, and cannot hang from a bar for more than 3 seconds. I guess he's at a 5 year old level for strength, at best, like the test showed. He should have been working on some of this in DAPE though, so how much worse would he be without that?
