Continuous stiffness testing device with participant positioned for the measurement of lumbar spine stiffness. The device measures displacement which is produced by loads applied to the vertical rod. The software quantifies stiffness values as a ratio between the applied force and the resultant displacement. The weight of the unloaded roller is ~17 N. Each additional mass increment is ~11 N
