Book excerpt: Even though the osteopathic profession is over 100 years old, very little literature has been available to assist the public in better understanding osteopathic medicine. Perhaps this is the primary reason many persons cling to "old wives tales" in their concept of this uniquely American medical profession.It is extremely difficult, if not impossible, to relate in a few brief pages the history, nature, philosophy, methods, and processes of development of any profession and do it justice. Therefore, perhaps this effort to introduce once again osteopathic medicine to the public will encourage others to articulate their insights into osteopathic medicine and complement the work of ones who have tried.This book is written by a layman for the lay reader. Much of the information has been gleaned from the few written sources available and from personal taped interviews with more than thirty persons in the osteopathic profession and ones related to it by employment and dedication. Some of the information has not previously been widely disseminated to the public. Nonetheless, it is a documented part of the osteopathic story.The remainder of the information in the book reflects the author's observations and opinions based on years of experience with, appreciation for, and commitment to the osteopathic profession.The author hopes The Difference a D.O. Makes will make a positive difference in the public's understanding of osteopathic medicine.Bob E.
