This edition is a significantly expanded version of Functional Performance. It has been a labor of love for many people who've been instrumental in making it the best book it could possibly be.
We thank our many excellent authors for their thoughtful contributions and patience during a lengthy revision process. We also thank our reviewers, who offered helpful observations that have greatly improved the final product. We thank Melissa Spor, who provided technical writing assistance, and Rebecca and Jordan Bray who were instrumental in developing the online materials.
We thank F. A. Davis for its continuing support and confidence in this project. In particular, Christa Fratantoro, Rose Foltz, George Lang, Amelia Bevins, Nicole Liccio, Megan Chandler, Carolyn O'Brien, and Bob Butler. Our sincere apologies if we left anyone off this list; many F. A. Davis staff work hard and effectively behind the scenes.
We appreciate the input from our students over the years, and we are deeply grateful to the many clients who have enabled us to learn from their experiences. We also appreciate the students who helped us refine the content of the book, responding to material, checking references, and otherwise helping us enhance the product. We are grateful to the many people who have read the book, and especially those who contacted us with suggestions or posted reviews that helped us continue to improve it.
And, as always, we thank our families. The process of bringing this book to completion has been a very long term, and at times intensive, effort, and they've not only provided helpful input, but have also cooked meals, handled household chores, and been cheerleaders during the process. Patrick Bray, Lisa Gomersall and Aaron Bray, Rebecca and Jordan Bray, and Tom Haas have our profound gratitude.
