  • Patent number: 7293363
    Abstract: A dual line protractor fixed to a central axis which has two housings, each housing having a spool with retractable lines, the housings and spools being rotatably attached to the central axis. The spools and housings rotate independently of each other on the central axis. The lines can be extended from the spools and the tips of the lines are attached to anatomical landmarks on first and second body members. The protractor is placed on a joint between the first and second body members. The lines extend from the spools and housings over degree marks on the protractor. The difference between the degree marks provide the angle between the body members at the joint. The application of the dual line protractor for these measurements is simple and rapid, requiring only a few minutes, so that the range of motion of several joints with several repeat measurements can be performed in a relatively short period of time.
