In its Fourth Edition, this popular National Board of Chiropractic Examiners reference text is updated and contains 125 more illustrations. Designed to teach correct evaluation and performance of basic orthopaedic and neurological tests, chapters are organized by region starting with the upper extremities progressing to lower extremities. Each test is presented on one page or two facing pages with photographs that demonstrate the performance of the test. Also includes anatomical drawings. Information discovered by these and other diagnostic tests allows the chiropractor to obtain patient diagnosis and hone logical examination patterns for accuracy in the determination of mechanisms of injury.
