In other examples, projections 14, FIG. 5, may radially extend from body 12 at different angles, as indicated at 20, 22, and 24. In other examples, projections 14, FIG. 6, may be cylindrically shaped with rounded ends or may also be cylindrically shaped with flat ends, as shown in FIG. 7. Projections 14, FIGS. 1-7, may also extend over the length, l-31, FIGS. 1 and 3 of body 12, e.g., in a right angle pattern, as shown in FIG. 8A, in a helical pattern, as shown in FIG. 8B, in a wave pattern, as shown in FIG. 8C, in a Z pattern, as shown in FIG. 8D, or in a pattern perpendicular to longitudinal axis 15, as shown in FIG. 8E. In other designs, the plurality of shaped projections 14 may extend over body 12 in an individual pattern as shown in FIGS. 9A and 9B. Each of the plurality of shaped projections 14, FIGS. 1-9B, preferably radially, extends about inch to about 3 inches from body 12, e.g., as shown by r-70, FIG. 2. In one example, soft device 10, FIGS. 1-3, may include eleven projections 14. In another example, soft device 10, FIG. 10, indicated at 41, may have twelve projections 14. In other examples, device 10 may have as few as 6 projections or as many as 20 projections 14, although device 10 may have any number of projections of various shapes, disclosed above, depending on the therapeutic use of device 10.

[0054] In another example, one or more of the density of body 12 and the diameter of body 12 in combination with the shape of projections 14 are preferably chosen to mobilize soft tissue structures of the human body which may include, inter alia, the Quadriceps, Hamstrings, Rhomboids, Rotator cuff, Glutes/Piriformis, Iliotibial band, Achilles tendon, Calf, feet, Head and Neck. In this example, often referred to as firm device 10, the density of the pliable material of body 12 is in the range of about 2.0 lb/ft.sup.2 to about 12 lb/ft.sup.3, e.g., preferably about 4 lb/ft.sup.3. The diameter, d-27, FIG. 2, of body 12 is in the range of about 3 inches to about 8 inches, e.g., preferably about 3.5 or 7 inches. The length of body 12, length l-31, FIG. 3, is in the range of about 2 inches to about 36 inches. In one preferred example, body 12 has a diameter of about 3 inches and a length of about 8 inches. In yet another example, body 12 has a diameter of about 3.5 inches and a length of about 12 inches. In yet another example, body 12 has a diameter of about 7 inches and a length of about 18 inches. In another example, body 12 has a diameter of about 7 inches and a length of about 36 inches. Similar as discussed above, the plurality of shaped projections 14 have a predetermined shaped as discussed above with reference to FIGS. 1-10 and preferably radially extend about inch to about 3 inches from body 12. FIG. 10 shows an example of firm device 10, indicated at 43. In this example, projections 14 may have a triangle shape as shown. In this design, device 10 has about thirteen projections 14, although device 10 could have any number of projections of various shapes, discussed above, depending on the therapeutic use of device 10.

[0055] In yet another example, the one or more of density of body 12 and the diameter of body 12 in combination with the shape of projections 14 are preferably chosen to mobilization soft tissue structures of the human body which may include, inter alia, the Quadriceps, Hamstrings, Rhomboids, Upper Trapezius, Forearm, Rotator cuff, Glutes, Piriformis, Calf, Feet, Head and Neck. In this example, which may be referred to as hard device 10, the density of the pliable material of body 12 is in the range of about 4.0 lb/ft.sup.2 to about 12 lb/ft.sup.3, e.g., preferably about 6 lb/ft.sup.3. The diameter, d-27, FIG. 2, of body 12 is in the range of about 3 inches to about 8 inches, e.g., preferably about 3.5 or 7 inches. The length of body 12, length l-31, FIG. 3, is in the range of about 2 inches to about 36 inches. In one preferred example, body 12 has a diameter of about 3 inches and a length of about 8 inches. In yet another example, body 12 has a diameter of about 3.5 inches and a length of about 12 inches. In another example, body 12 has a diameter of about 7 inches and a length of about 18 inches. In another example, body 12 has a diameter of about 7 inches and a length of about 36 inches. Similar as discussed above, the plurality of shaped projections 14 have a predetermined shaped as discussed above with reference to FIGS. 1-10 and preferably radially extend about inch to about 3 inches from body 12. FIG. 10 shows an example of device 10, indicated at 45. In this example, device 10 may include about seven projections with a curved shape as shown, although device 10 may have any number of projections of various shapes, discussed above, depending on the therapeutic use of device 10.

[0056] In the examples above, one or more of the predetermined density and the predetermined diameter in combination with the predetermined shape of the projections effectively mobilize soft tissue structures of the human body. In other examples, one or more of the predetermined density and predetermined diameter in combination with the predetermined shape of the projections may be chosen to effectively optimize body core strength and optimize balance training and/or efficiently break up collagenous fibers of soft tissue structures and/or enhance flexibility of soft tissue structures and/or enhance distensibility of soft tissue structures. Moreover, projections 14 stabilize device 10 when used for body core strength and balance training.

[0057] Examples of the operation of therapeutic, fitness and sports enhancement device 10 with projections 14 of one or more embodiments of this invention used to mobilize soft tissue structures of the human body and/or effectively optimize body core strength and optimize balance training and/or efficiently break up collagenous fibers of soft tissue structures and/or enhance flexibility of soft tissue structures and/or enhance distensibility of soft tissue structures are shown in FIGS. 11-A-11M. For example, FIG. 11A shows an example of device 10 being used to mobilize the soft tissue of Quadriceps 98. When moved back and forth in direction 100, projections 14 extend into the soft tissue of Quadriceps 98 and mobilize Quadriceps 98. This breaks up the collagenous fibers of the Quadriceps 98, enhances flexibility and enhances distensibility of Quadriceps 98.

[0058] In other examples, therapeutic, fitness, and sports enhancement device 10 may be used in a similar manner as discussed above with reference to FIG. 11A to mobilize soft tissue structures of the Iliotibial band (ITB), as shown in FIG. 11B, the inner thigh, as shown in FIG. 11C, the Glutes, as shown in FIG. 11E, the Piriformis, as shown in FIG. 11F, the Hamstrings, as shown in FIG. 11 G, the Lumbar region, as shown in FIG. 11H, the Rhomboids, as shown in FIG. 11I, the Thoracic region (Mid/Lower Back), as shown in FIGS. 11J and 11K, the Shins, as shown in FIG. 11L, and the calf, as shown in FIG. 11M.

[0059] Examples of the operation of firm and/or hard therapeutic, fitness, and sports enhancement device 10 used to mobilize soft tissue structures of the human body, break up collagenous fibers and/or enhance flexibility and/or enhance distensibility are shown in FIGS. 12A-12I. For example, device 10 may be used to effectively mobilize soft tissue, break up collagenous fibers and/or enhance flexibility and distensibility of the Neck, as shown in FIG. 12A, the upper Neck, as shown in FIG. 12B, the upper Trapezius, as shown in FIG. 12C, the shoulder and Rotator cuff, as shown in FIG. 12D, the Rhomboids, as shown in FIG. 12E, the Lower Back, as shown in FIG. 12F, the arch of the foot, as shown in FIG. 12G, the Achilles, as shown in FIG. 12H, and the Calf, as shown in FIG. 12I.

[0060] The result is therapeutic, fitness and sports enhancement device 10 with a unique combination of one or more of density and diameter and the shape of projections 14 maximizes mobilization of soft tissue structures. Typical target soft tissue mobilized by the plurality of shaped projections 14 may include muscles, tendons, ligaments fascia of the human body and the like. Mobilization of soft tissue by projections 14 massages soft tissue and breaks up scar tissue. This increases flexibility of soft tissue, decreases muscle soreness, relieves joint stress, decreases neuromuscular hypertonicity, increases joint range motion and extensibility of musculotendinous junctions, optimizes soft tissue distensibility, increases neuromuscular efficiency, increases flexibility and helps maintain normal functional muscle length. These benefits enhance recovery of injuries when used as a therapeutic tool, maximize sports performance, and improved fitness. Device 10 also optimizes body core strength and optimizes balance training.

[0061] In one example, therapeutic fitness and sports enhancement device 10, FIGS. 1-12I may be manufactured using extrusion process as know by those skilled in the art. In this example, raw material in the form of granules of plastic, e.g., polyethylene, is put hopper 150, FIG. 13, and fed into heated chamber 152. Press 154 pushes the material in chamber 152 through die 156. Die plate has the shape of body 12 with projections 14. In this example, die 14 has a shape similar to body 12, FIGS. 1-3, with rounded projections 14. In other examples, die 156 can be shaped with any configuration to manufacture device 10 with the projections shaped as shown in FIGS. 1-9B, or any other various shape known by those skilled in the art. The extruded material is then allowed to cure in a controlled temperature room to strengthen the material and provide a more finished look to device 10.

[0062] In another example, therapeutic fitness and sports enhancement device 10, FIGS. 1-12I may be manufactured using molding process, as known to those skilled in the art. In this example, raw material, e.g., beads of expandable polyethylene (EPE), is put into a hopper 160, FIG. 14, and then fed into chamber 162 which includes a die in the shape of device 10, FIGS. 1-12I. The chamber is heated and chamber 162 is pressurized. This allows the beads of EPE to shape to the contours of the die. Then a curing phase occurs to allow the EPE form the shape of device 10, e.g., as shown in FIGS. 1-9B. This curing phase occurs in a heated room to allow the polymer to cure.

[0063] In another example, therapeutic fitness and sports enhancement device 10, may be manufactured with a large sheet of the pliable material is cut using a high speed vertical band saw which forms cylindrically shaped body 12 and the plurality of shaped projections 14 thereon.

[0064] In yet another example, device 10 may include cylindrically shaped body 12, FIG. 15 that includes a plurality of bonded sections, e.g., sections 19, 21, 23, and 25, each having a plurality of shaped projections 14 thereon of a predetermined type, e.g., as shown in any of FIGS. 1-9B. Each of sections 19-25, FIG. 15, is similarly made of a pliable material, e.g., closed-cell polyethylene foam, such as MINICEL L200, L300 or L380 discussed above, and is bonded to each other using a high bonding adhesive. The sheets of the pliable material used for the plurality of bonded sections, e.g., sections 19-25, typically has predetermined width, e.g., about 2 inches to 3 inches, or up to 4 inches, although the sheets of pliable material and the resulting width of sections 19-25 may have any width as known to those skilled in the art. The shape of the plurality of shaped projections 16 and cylindrically shaped body 12 made of sections 19-25 is similarly formed using a high speed versatile band saw, as discussed above.

[0065] In another embodiment, therapeutic, fitness, and sports enhancement device 10, FIG. 16, of this invention includes cylindrically shaped core 12 and overlay 13 about core 12. Similar as discussed above, one or more of the predetermined density and the predetermined diameter of body 12 and overlay 13 in combination with the shape of the projections are chosen to effectively mobilize soft tissue structures of the human body. Overlay 13 includes a plurality of shaped projections 14, similar as discussed above with reference to FIGS. 1-9B, which are shaped to mobilize soft tissue structures of the human body and/or improve body core strength and balance training and/or enhance flexibility and/or optimize soft tissue distensibility. Core 12 is similarly made of pliable material, as discussed above. Overlay 13 is typically made of MINICEL L200, L300 or L380. Body 12 and overlay 13 with projections 14 thereon may also be formed from an extrusion process or a die cast process or cut by a high speed foam band saw, as known to those skilled in the art. Similar as discussed above with reference to FIG. 2, projections 14 on overlay 13, FIG. 16, radially extends about inches to about 3 inches from overlay 13, e.g., as indicated at r-70, FIG. 2, as needed to maximize soft tissue mobilization, and improve balance and core strength training, enhance flexibility and optimize soft tissue distensibility. Therapeutic, fitness, and sports enhancement device preferably has a density and d10 may have a length as indicated by l-31, FIG. 16, and has a diameter, d-27, FIG. 17, similar to any of the embodiment of device 10 discussed above with reference to FIGS. 1-9B.

[0066] In one embodiment, therapeutic, fitness, and sports enhancement device 10, FIGS. 1-16, may include end caps 212, FIG. 18, on each end of device 10.

[0067] Therapeutic, fitness, and sports enhancement device 10, FIGS. 1-18, may also include handle 300, FIG. 19A. Handle 300 preferably extends though opening 302, FIG. 19B, having inner diameter d-304, which can vary from about inch to about 5 inches, e.g., about 2 inches as shown in FIG. 19C. Opening 302, FIG. 19B, with inner diameter d-304 is typically created using an extrusion process. Inner sleeve 306 fits inside opening 302 and handle 300 extends through inner sleeve 306. Handle 300 may be used for gripping to allow the ridged roll to roll over the soft tissue of the body, e.g., the Quadriceps, Upper Trapezius, Iliotibial band, and the like, as discussed above with reference to FIGS. 11A-12I.
