Abstract:
1. A method for relieving symptoms of lumbar pain associated with flexion of a spinal segment of a patient, said method comprising: increasing the bending stiffness of the spinal segment by an amount in the range from 0.1 Nm/deg to 2 Nm/deg., wherein the bending stiffness is increased by coupling an elastic constraint between a superior spinous process and an inferior spinous process or between an L5 spinous process and a sacrum, wherein the elastic constraint has an elastic stiffness in the range from 7.5 N/mm to 40 N/mm, and wherein the constraint is positioned at a distance in the range from 25 mm to 75 mm in a posterior direction from a center of rotation of the spinal segment.
