Learn how to apply the new principles for evaluation of musculoskeletal permanent impairments using the "Guides Sixth Impairment Training Workbook" series, developed by the American Medical Association (AMA). Based on the sixth edition of the "Guides to the Evaluation of Permanent Impairment (Guides Sixth)", these three new, resourceful training workbooks focus on the musculoskeletal systems, including the spine, the lower extremity and the upper extremity. Each workbook contains more than 125 content-based questions with rationales explaining the correct answer. Also included in this title is a 25-question self-test to assess your improved understanding of the Guides Sixth methodology and its application. Let impairment and training experts walk you through new concepts found in this edition and help you: understand the new diagnosis-based impairment (DBI) rating and how it differs from the prior editions' use of the diagnosis-related estimate (DRE) and/or range of motion methods as the primary choice for evaluating musculoskeletal conditions or illness; become familiar with new criteria for differentiators and how objective tests are emphasized in the clinical assessment; and, take into account individual variation and treatment effects in assessing each musculoskeletal system. Delivered in an easy-to-use format and geared toward a multi-disciplinary audience, each workbook contains tips and strategies to assist adjusters, physicians and lawyers with the application of the new concepts presented in Guides Sixth. Emphasis is placed on correctly applying the new grid construct and determining impairment with consideration to physical examination, functional history and clinical studies. Each module illustrates key differences between Guides Sixth and prior editions, allowing you to easily recognize changes as you start using the sixth edition in your assessment practices.
