Multidimensional Mobilization of Lumbar, Pelvic, and Hip Joints

Abstract

A device for multidimensional mobilization of lumbar, pelvic, and hip joints with a generally concave upper surface connected to a generally convex lower surface is disclosed, wherein the generally concave upper surface has a recess to cradle a sacrum.

What is claimed is: 
     
         1 . A device for multidimensional mobilization of lumbar, pelvic, and hip joints comprising a generally concave upper surface connected to a generally convex lower surface, wherein the generally concave upper surface has a recess to cradle a sacrum. 
     
     
         2 . The device of  claim 1 , wherein the recess to cradle the sacrum has a bilateral symmetry and is elliptical, ovate, triangular, or trapezoidal in contour. 
     
     
         3 . The device of  claim 1 , wherein the device is made of one or more materials selected from the group consisting of rubber, plastic, and wood. 
     
     
         4 . The device of  claim 3 , wherein the generally concave upper surface and the generally convex lower surface are made of different materials. 
     
     
         5 . The device of  claim 1  further comprising a lip formed between the generally concave upper surface and the generally convex lower surface. 
     
     
         6 . The device of  claim 5 , wherein the lip limits the degree of tilting of the device from a neutral position when the generally concave upper surface is in a position substantially parallel to the ground or other flat surface, to between about 25 degrees to about 30 degrees of tilt when the generally concave upper surface is in about 25 degrees to about 30 degrees of tilt in relation to the ground or other flat surface. 
     
     
         7 . The device of  claim 1 , wherein the convex lower surface has a pre-set pattern of ridges, grooves, or planar portions. 
     
     
         8 . The device of  claim 7 , wherein the pre-set pattern of ridges, grooves, or planar portions are generally equidistant and form a half spherical polyhedron with twelve regions. 
     
     
         9 . The device of  claim 8 , wherein the ridges, grooves, or planar portions converge at the half spherical polyhedron nadir. 
     
     
         10 . The device of  claim 1  further comprising indicia on the upper surface. 
     
     
         11 . The device of  claim 10 , wherein the indicia comprises markings selected from the groups consisting of numbers of a face of a clock, letters of a compass, and directional arrows of a compass. 
     
     
         12 . The device of  claim 1  further comprising a sidewall around the periphery of the generally concave upper surface. 
     
     
         13 . The device of  claim 12  further comprising indicia on the sidewall. 
     
     
         14 . The device of  claim 13 , wherein the indicia comprises markings selected from the groups consisting of numbers of a face of a clock, letters of a compass, or directional arrows of a compass. 
     
     
         15 . A method of multidimensional mobilization of lumbar, pelvic, and hip joints comprising the steps of
 lying supine on a flat surface with the device of  claim 1  beneath the user's sacrum, and   performing one or more of anterior pelvic tilt, posterior pelvic tilt, left lateral pelvic tilt, right lateral pelvic tilt, pelvic and hip rotation, and diagonal pelvic tilt stretches.
