This outstanding third edition features a framework for understanding and applying the systematic process of research. This edition keeps the reader apprised of the current and future focus of rehabilitation research and emphasizes the importance of the joint effort of the producers and consumers of research. In this edition, the author has taken an important leap from the context of physical therapy research to the broader context of rehabilitation research. The addition of research examples and research approaches used by occupational therapists, speech-language pathologists and audiologists, physiatrists, athletic trainers, and prosthetists and orthotists has added richness to the text. All of this plus a new chapter on Synthesizing Bodies of Evidence (26).
