Youre absolutly wright that were retraining the hole hand.Sorry that I dont have a video of the hand in action.
I have tried to pluck with M alone.Sometimes it returns to the start position,sometimes it doesnt.It could be that tension is the bad gay,but I try to be as relaxed as possible when I do my exersises.Its more the feeling of the finger thats different from time to time.
By the way,I think I have found a good exersise for the dystonic M finger(the finger that used to curl into the palm of the hand.Had no control over that finger.Now I have a certain degree of control).I place I/C on the second string and pluck the first/third string with M/A.It feels good when I do this.Kind of give me more control.But I have to do this for a longer period of time and see what happends.
