Abstract
A dynamic spine stabilizer moves under the control of spinal motion providing increased mechanical support within a central zone corresponding substantially to the neutral zone of the injured spine. The dynamic spine stabilizer includes a support assembly and a resistance assembly associated with the support assembly. The resistance assembly generates greater increase in mechanical force during movement within the central zone and lesser increase in mechanical force during movement beyond the central zone. A method for using the stabilizer is also disclosed.
