I am absolutely 100% certain that in MY case, M is dystonic.
I cannot say what the situation is in your case without seeing your hand.Initially, when I first had FD, my index finger would curl tightly into the palm if I tried to play with M - clearly 'I' was overcompensating for M's lack of movement. My 'workaround' technique for years was to play with I and P, avoiding M. Clearly if my index was dystonic, I wouldn't be able to use it.
Where do you get your stats from?: "I would say that in 90 % of all cases the finger that curls in is dystonic,the one that sticks out is the compensating one"
