Abstract: A device and process for measuring cervical range of motion about three axes comprises an eyeglass frame which is supported on the nose and ears of a patient. A pendulum angle finder and a compass and the pendulum is mounted a horizontal axis and the compass needle is mounted about a vertical axis. The angle finder and compass are mounted on the eyeglass frame with a clamp that permits rotating the angle finder 90.degree. to permit measuring angles about two mutually perpendicular axes in the horizontal plane to permit tri-planar angle measurements. The angle finder and compass can be adjusted to a zero position and cervical range of motion is then measured through the use of angle indictor scales provided on the angle finder and compass. Readings may be made about one, two, or all three axes of rotation.
