The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
We claim:
1. A foot lifter orthesis comprising:
a dorsal leg shell, extending over the rear foot, which can be fixed by a strapping means to the calf of the orthesis wearer and which has a forefoot shell section constructed in one piece which extends to a point below the foot sole region, wherein the leg shell exhibits a low resistance in dorsal foot bending and a high resistance compensating for the foot and shoe mass in plantar foot bending with at least one resilient inlay, which extends approximately parallel to and at a short distance from an edge of the leg shell from the calf region thereof to a point below the forefoot shell section.
2. The foot lifter orthesis according to claim 1, wherein said dorsal leg shell includes plastic.
3. The foot lifter orthesis according to claim 1, wherein said leg shell includes soft, flexible plastic.
4. The foot lifter orthesis according to claim 1, wherein said at least one resilient inlay includes at least one spring wire.
5. The foot lifter orthesis according to claim 1, wherein said at least one resilient inlay includes a pair of spring wires.
6. The foot lifter orthesis according to claim 1, wherein said edge of said leg shell is an inner edge.
7. The foot lifter orthesis according to claim 1, wherein said edge of said leg shell is an outer edge.
8. The foot lifter orthesis according to claim 5, wherein said edge of said leg shell is an inner edge.
9. The foot lifter orthesis according to claim 5, wherein said edge of said leg shell is an outer edge.
10. The foot lifter orthesis according to claim 1, wherein said leg shell includes a low-density polyethylene.
11. The foot lifter orthesis according to claim 1, wherein said leg shell includes an EVA.
12. The foot lifter orthesis according to claim 5, wherein said at least one spring wire inlay ends approximately in the lower region of the heel bone.
13. The foot lifter orthesis according to claim 5, wherein said at least one spring wire inlay is at least partially surrounded by plastic.
14. The foot lifter orthesis according to claim 1, wherein a central rib which is formed integrally in the rear heel region of the leg shell and on the rear side thereof, protrudes beyond the shoe edge of footwear put on by an orthesis wearer.
15. A method of forming a foot lifter orthesis comprising:
molding with soft, flexible plastic a dorsal leg shell, extending over the rear foot, which can be fixed by a strapping means to the calf of the orthesis wearer and which has a forefoot shell section constructed in one piece which extends to a point below the foot sole region; and
encasing in plastic at least one resilient inlay, which extends approximately parallel to and at a short distance from an edge of the leg shell from the calf region thereof to a point below the forefoot shell section., wherein the leg shell exhibits a low resistance in dorsal foot bending and a high resistance compensating for the foot and shoe mass in plantar foot bending.
