I want to express my gratitude to my mentors and colleagues who have taught me the art of neuromuscular medicine and continue to do so. I would be remiss if I did not thank all the patients whom I have had the honor to learn from all these years. Most of all I would like to thank and dedicate this book to my wife, Mary, and my children, Joseph, Erin, Michael, and Katie, for their unconditional love and support over the years.

To the newest addition to our lives, Isabel Reagle Russell, in the hope that someday you will see this undertaking as a source of both pride and motivation.
