The systematic and consistent approach to measuring range of motion through simple photos, diagrams, and animations. - For every joint, reference points and the neutral-0 position are defined. - The normal values are shown for every joint and for all complete ranges of motion. - Length and circumference of the extremities are indicated as well - Pitfalls are emphasized with yellow boxes - For every joint, a documentation protocol can be printed showing the range of motion; measurements obtained at follow-up can be included, as well. - References to the literature are linked to the free Medline site of Medscape, allowing immediate and convenient access to abstracts. - CME: CME credit hours are available by means of filling out a questionnaire included with the product (pending approval by ACCNE, USA)
