Kat is esentially right in her definition. Dystonia is writhing movements
and painful almost constant spasms in the affected limbs. I have dystonic
postures in all four limbs, unfortunately. Dystonia can affect sleep,
movement, postures, the tightness of limbs.

A GREAT WEBSITE TO GO TO TO FIND OUT MORE ABOUT IT IS:

Hope this helps.
