For physicians having to perform assessments, this volume contains 71 case studies on evaluating disabilities and impairments of different body systems. Case studies demonstrate the principles of the American Medical Association's Guides to the Evaluation of Permanent Impairment, sixth edition, and correspond to its chapters. It describes the thought process of impairment evaluation and the mechanics necessary to arrive at the correct impairment ratings for the Fourth, Fifth, and Sixth Editions of the Guides for comparison. Most of the cases are of the upper and lower extremities and spinal problems. For this edition, cases have been rewritten and reassessed, with new cases added. The book may also be useful to attorneys, claims professionals, and case managers working on workers' compensation, personal injury, and automobile casualty cases, and professionals studying for exams in assessment.
