Yes. Given enough time, effort, and interest, it is amazing what they can accomplish... but it takes enough time and effort, that kids with these kinds of motor skills problems will master a smaller set of physical-based activities.
I still haven't mastered writing. Can barely ride a bike. Can NOT walk across the parking lot without tripping on my own two feet. But... I type at about 55 wpm (out of practice these days), play piano, do handicrafts (knitting, etc.)...
