Claim 17:
18. A method of massaging using a therapeutic device to provide a therapeutic effect comprising:
providing an upper massage surface having a central spinous channel, a first domed portion on a first lateral side of the central spinous channel and a second domed portion on a second lateral side of the central spinous channel, wherein the first and second domed portions each comprise a circumferential edge at its base and an outer curved surface with a plurality of projections extending upwardly and outwardly from the outer curved surface, the upper massage surface being applied to a body of a user with the central spinous channel accommodating the spine of the user;
forming a lower base surface with frictional capacity to reduce sliding on a surface;
providing a front edge;
providing a rear edge, the upper massage surface extending between the front edge and the rear edge;
providing a first lateral edge on one side of the therapeutic device and a second lateral edge on an opposing side of the therapeutic device which are away from the spine of the user, and wherein a distance between the first and second lateral edges is greater than a distance between the front edge and the rear edge so that the therapeutic device can fit between the back of the user and a seating surface on which the user is positioned;
providing on each side of the central spinous channel, a plurality of large projections on a periphery of the upper massage surface and a plurality of small projections in an internal surface area defined by the plurality of large projections;
wherein the circumferential edges of each of the first and second domed portions intersect the periphery having the plurality of large projections and the internal surface area having the plurality of small projections on each side of the central spinous channel, respectively; and
heating the therapeutic device to a temperature to enhance the therapeutic effect.
