David Draper passed away unexpectedly in March 2021 during the production of this textbook. David was a contributing author for both the Therapeutic Ultrasound and Diathermy chapters since the first edition of this text. He was widely recognized as a preeminent scholar and authority in both of those areas. His contributions to the professional literature over many years were extensive and he significantly expanded the body of knowledge relative to how the clinician should use therapeutic modalities. More importantly, David was a good friend to me and he was quite simply a good human being. He will be missed both professionally and personally.
I would like to thank my Associate Publisher, Michael Weitz, my Project Developmental Editor, Peter Boyle, my Administrative Assistant, Melinda Avelar at McGraw Hill, and Adwiti Pradhan my Project Manager from MPS Limited for their assistance in this project. From the very beginning, their advice and direction have certainly been indispensible in its completion.
I would like to thank my sports medicine family at the University of North Carolina at Chapel Hill where I have spent almost my entire professional career. The clinical staff, my faculty colleagues, and my students, both past and present, have been an absolute pleasure to work with over so many truly incredible years. They have always been so kind and supportive of this old man and I have the utmost respect for each and every one of them. Most importantly, to my family … our two sons Brian and Zach and new daughter-in-law Megan…you are what make an effort such as this worthwhile. You guys have always kept me grounded and helped me maintain focus in both my personal and professional life and I am incredibly proud of you. And finally, to my wife Tena … I could not be more thankful that you and I found such a wonderful life in Chapel Hill. Over the last several years you have taught us all not only about the tenuous frailty of the human body, but also about the amazing resilience of the human spirit. You have truly been an inspiration.
