Thoroughly revised and updated, the 4th Edition features enhanced sections on evidence-based practice intervention outcomes and up-to-date coverage of the latest procedures, as well as full-color photographs and line art. "At a Glance" boxes let you quickly review each modality and illustrated "Treatment Strategies" boxes relate theory and physiological material directly to clinical practice. As a bonus, you'll also have access to the resources online at DavisPlus, including the new Modality Animated Learning Modules that visually reinforce core concepts in the text.
