Abstract: Apparatus for simultaneously measuring the range of motion in a full 360 degree by 180 degree dual axis range. The devices and software applications allow for real time measurement of total spine and extremity movements by analyzing both pitch and roll angles simultaneously. This provides the tester with an extremely accurate account of range of motion without the usual inaccuracies of individual turning into or away from the set movement plane. Furthermore, the small and easy positioning device and application software allow the system to function without dependency on gravity for accuracy of motion measurement.
