A method of measuring the range of motion of a joint or series of joints. Tests include the direct measurement of the angular displacement of a joint using a goniometer, flexometer, still-photography, or X-rays. There are many indirect methods that involve measuring the linear distances between two body segments, or between a body-part and an external object. These tests include the standing toe-touch test, and the sitting toe-touch test. Such indirect tests are quite easy to perform, but difficult to interpret because the movements are quite complex and it is not clear which joints and muscles are involved.
