Hi Wombat ~ Dystonia is "disordered tonicity" - the property of possessing tone.
And Dyspraxia is the impairment of ability to perform coordinated movements.
I hope that's what you wanted to know.
Anyway ~ WELCOME to NeuroTalk and i hope we hear more from you.

I'm sure you'll like it here. The people here are great and there's loads of information.
Take care and God bless! Hugs, Lee
