This paper describes the development of the measuring apparatus for spinal strength. It is used to help examine the clinical instability and the mechanical dysfunction of the spine due to degenerative changes and trauma. In this study, the measuring apparatus has the ability to change/control the angular velocity, and apply the Torque Feedback Control. The Torque Feedback Control makes it possible to apply the more simple torque to the specimens. The torsional test carried out by using a spring instead of a spinal specimen to verify the validity of Torque Feedback Control in this apparatus. The white rabbits' cadaveric spinal specimens were also utilized. As a result, we found that there were the significant differences between two conditions, Torque Feedback controlled and uncontrolled.
