A method for providing cyclic mobilization of the lumbar spine of a person includes providing a fluid-inflatable bag, positioning the bag behind and adjacent the lumbar region of the person, and alternately directing fluid to flow into and out of the bag to inflate and to deflate the bag to vary forces applied to the spine of the person thereby moving the spine through a range of degrees of lordosis. Also, apparatus for providing support and spinal movement to the lower back of a person includes a fluid-inflatable bag adapted to be positioned behind and adjacent the lumbar region of the person, a source of fluid under pressure, a conduit adapted to conduct the fluid between the source and the bag, and a regulator adapted for controlling the flow of the fluid in the conduit; the flow of fluid alternately causes inflation and deflation of the bag, and the inflation and deflation of the bag applies greater and lesser forces to move the spine of the person through a range of degrees of lordosis.
