This edition is dedicated to all those who have supported me and encouraged me to pursue my passion for physical therapy and biophysical agents. Thank you to my wife, Mary Helen, and daughters Kate and Caroline, who have fulfilled me with their joy, love, and support throughout my career and life, and to all the students I have ever had the privilege to know. Without you all, none of this would be possible.
I wish to dedicate this edition to the patients who inspire me every day to provide the best evidence-based physical therapy interventions, which may include the appropriate and unbiased use of biophysical agents.
