Musicians with Dystonia Bulletin Board

One of my personal beliefs is that the only FD any of us will ever know is our own. And people that don't have it won't even understand one.

"It" presents itself in so many different ways. And so far no one approach has been shown to be a cure for everyone that tries it.

The fact is, a lot of "musician's FD" very closely parallels the same FD people get from other repetitive actions like typing and writing. The only apparent difference is the variations in the movments involved.
I'd suggest you're just seeing a problem with the language.
IMHO, the "musician" part of the "name" implies nothing more than the activity that led to the problem.

In my experience, I would have said (and the doctors I saw did say) for at least 3 years that my condition was "task-specific" because I was only aware of malfunctions in touching the guitar. And yet I later came to realize that there were subtle issues in handling buttons, dialing telephones, etc., that just wouldn't matter in terms of doing that job. In becoming more aware of the postures, movements and sensations that were indeed part of the FD (or whatever else anyone wants to call it) away from the instrument, I was able to work out measurable improvement to those things that then led to major improvements on the guitar.
