Physical medicine and rehabilitation (PM&R) is one of the broadest and most challenging specialties in medicine. Physiatrists see patients of all age groups with impairments of every organ system and must have a keen understanding of anatomy, biomechanics, ergonomics, exercise physiology, kinesiology, neurophysiology, pharmacology, and psychology. They not only prescribe medications and perform procedures, but also prescribe prosthetics, orthotics, splints, and complex medical equipment. They lead interdisciplinary teams that address the holistic bio-psycho-social and spiritual needs of people with disabling conditions. In PM&R, board certification has three components: The first component, Part I, is a written examination testing medical knowledge; the second component, Part II, is an oral examination that tests clinical practice skills. The third component, Part III, is maintenance of certification. The Accreditation Committee for Graduate Medical Education defined six core competencies for physicians: medical knowledge, clinical care, practice-based learning, communication, professionalism, and systems-based practice. Part I tests the first of these competencies, while Part II tests the remainder. This workbook is an additional tool, unique in its format. It walks the reader through cases in an interactive format. The cases are structured in a similar format to The American Board of Physical Medicine and Rehabilitation (ABPMR) Part II. The content mirrors the exam outline, which is available on the ABPMR website. The exam consists of questions about case vignettes. Each vignette fits into one or more diagnostic categories, and each may focus on one or more evaluation or management skills. Each case tests five clinical skills: data acquisition, problem-solving, patient management, system-based practice, and interpersonal and communication skills. While the text is intended as a board review workbook to be used in preparation for the Part II exam, other audiences will find it helpful as well.
