Principles of Deglutition

Dr. Shaker is one the founders of the Dysphagia Research Society and the Medical College of Wisconin's Dysphagia Institute.  Dr. Shaker is internationally recognized for his studies of deglutition and deglutition disorders, gastroesophageal reflux disease and cerebral cortical control of gastrointestinal sensory motor function. His research has led to some of the seminal discoveries in the area of airway protection and has opened new avenues of investigation and treatment for patients with swallowing disorders. He developed the rehabilitative exercises for treatment of upper esophageal sphincter dysphagia: The `Shaker Exercises` commonly used in clinical practice.

From the reviews:“This book examines the principles of swallowing, including basic physiology, and related disorders. … The objectives are worthy, as a comprehensive book on this topic is difficult to come by. It is written for anyone interested in learning more about swallowing and its related disorders. … The chapters are a collection of articles on the various topics, each with pertinent illustrations/graphics. … This is a useful, up-to-date, comprehensive reference on swallowing and its related disorders.” (Inna Athar Husain, Doody’s Review Service, February, 2013)
