Hi, sorry I wasn't sure where to post this! Just a query really, my 5 year old ds was diagnosed with asd back in the summer. I've noticed he doesn't seem to have much muscle strength behind him, I mean I know he's only five lol but he struggles with things like piecing Lego together or pulling an xmas cracker there just seems to be nothing behind him ! Is this what would be classed as low muscle tone? Is it something that can be improved with exercise etc?
