From David Leisner:
"Since I am not a member of and never read comments in the Delcamp forum and do not have the time or the inclination to get involved, I have asked Jean Feys, whom I did not know until he wrote to me about this thread today and asked me to comment, to kindly post a single statement by me. This will be my only statement in this thread.
The comments of a few of the contributors were, in my opinion, extraordinarily ignorant, arrogant and disrespectful. The comments of "Guit-box" are particularly disturbing in these ways. If he (I'm assuming it's a he) or anyone had simply asked me for a list of students who have benefited from my teaching, I would have been happy to supply it. And I will do just that now. In the limited time I have available to me at the moment, here is a list of names, just off the top of my head, of musicians who I have either completely cured or significantly helped on the way to curing their focal dystonia: Guitarists - Brian Hays (who is currently funding the Johns Hopkins University/Peabody FD research program because of his experience of being cured of FD by me), Mark Ashford, Christian Verspay, Matthew Marshall, Sean Behrens, Steve Rings, Pam Kimmel, Eduardo Gonzalez, Pierluigi Serraino, Michael Black, Vincenzo (I can't remember his last name, from Italy, whose FD in the thumb disappeared within months in the early 2000's after studying with me, the fastest cure to date amongst my students), Flavio Ciatto, and a very famous guitarist who wishes to remain private about his FD experience - David Griego, flutist, Bernard Zinck, violinist, Brian Bloye, pianist, Myra Melford, pianist, Eli Wilson, percussionist, and Gustavo Peterlevitz, pianist. There are more, but these are the names I remember quickly at this moment.
Guit-box also comments that "you won't see large-muscle arm movements" when watching me on video. That is exactly the point. One begins with gross exaggeration of movement and ends with little or no excessive movement. This is described succinctly in the section, called "The Refinement Process" on p. 110-11 in my book. The very same section answers the far more respectful questions of Todd Tipton, who honestly wondered "how the large muscle ideas are applied outside of a few isolated circumstances." I believe, Todd, you will find the answer you seek in that section.
The unteachable Mr. Guit-box reports that [in the four lessons I apparently gave this person who hides his true identity behind his made-up user name] "all we did was swing from the elbow for 4 days". That aspect of the lessons would have occupied about 5 minutes' worth in the very first lesson. I am very generous with my time with FD sufferers - each of the 4 lessons is usually about 75-90 minutes long. Multiply that by 4, and you can do the math to see the actual percentage of time taken up by this one simple idea that is just the beginning of a huge amount of material that is offered in the 4 lessons. If, in fact, that was all that Guitar-box retained from his lessons with me, then he certainly did not get his money's worth. And that, I would venture to say, was not my fault.
My book was written with the utmost care and precision, and read and re-read many, many times by not only me, but the superb Oxford University Press Editor and several of my friends, for accuracy, clarity and expression. If some ideas failed to communicate through words, videos, photos and illustrations, then it is most certainly on me. However, I can also say that it is apparent in some of the comments that my book may not have been read by them with the utmost care and precision on their part. If you're going to criticize, be sure you have read everything carefully first.
It is true that the large-muscle ideas of Chapter 5 are very hard to communicate in just words. That is why the bulk of the videos on the companion website are associated with that chapter. But even with the videos, there really is no substitution for in-person, hands-on demonstration (which, in fact, I mention in the book). If you can catch me at a master class or a workshop, perhaps you'll ask me about these issues in person and have me demonstrate some things for you. I'm always happy to do that. Or you're welcome to take a private lesson from me at the "huge $" price that I charge, which virtually everyone who has ever taken a private lesson with me has felt was worth every penny. I get a lot accomplished in a short amount of time, and in the case of those who come to me with injuries of various sorts, I have a reputation for solving their problems quickly and efficiently.
Thanks for your attention, and thanks to Jean Feys for his support and for allowing me to speak through him on this forum."
