ABSTRACT:
A generally hemispheric shaped dome, which has a flat nonskid base, is on the order of 11/2 inches (3.8 cm.) high from base to apex and is made of a hard nonresilient material. It is placed on a substantially rigid support surface which at least coincides in area with the major portion of a person's back from buttocks to shoulder. A person having an area of pain in his or her back presses his or her back against the dome with the apex of the dome at or adjacent to the area of greatest pain, but not against the spinal column.
