<p>An instrument for measuring more precisely the range of motion of body members such as the spine including the Cervical, Thoracic and Lumbar sections, and also shoulders, hips, knees and others which have the capability of movement. The utilization of detector and monitor provides an extremely accurate range of motion measurement. The microprocessor will also print out a permanent record of the measurement and other required information. The device (20) has a variable resistor (74) and a freely movable plum (76) that are movable relative to one another to provide signals transduced into degrees for indicating the range of motion of a body member.</p> |
