Abstract

The present invention is a restraint and method for stretching the plantar fascia. A foot plate in combination with a lifting member serves to elevate the phalanges and to reduce contracture of the MTP joints. Employing a leg support shell, side railings, and straps, the present invention is able to be worn at night unobstrusively but fixedly upon the lower limb. Padding throughout the present invention ensures comfort. The user can vary the angle of dorsiflexion of the phalanges by removing and attaching various lifting members to the foot plate.

Claims

1. A restraint for retaining a generally planar foot in a predetermined dorsiflexion position comprising:

a foot plate;

a lifting member located atop said foot plate; and

means for attaching said foot plate to an underside of a foot;

wherein said lifting member fixedly positions toes of the foot at a greater slope than the generally planar underside of the foot.

2. The restraint of claim 1, further comprising a leg support shell attached to and extending upwardly from said foot plate, wherein said leg support shell is formed to engage a lower leg and an ankle.

3. The restraint of claim 2, wherein said leg support shell is generally U-shaped.

4. The restraint of claim 2, further comprising a means for attaching said leg support shell to said foot plate.

5. The restraint of claim 4, wherein said means for attaching said leg support to said foot plate is a hinge comprising a male portion and a female portion which interengage.

6. The restraint of claim 2, further comprising means for attaching said leg support shell to the lower leg and the ankle.

7. The restraint of claim 6, wherein said means for attaching said leg support shell to the lower leg and the ankle is at least one strap means with hook and loop fastening strips.

8. The restraint of claim 2, wherein an angle of dorsiflexion between said foot plate and said leg support shell varies from about 85 degrees to 90 degrees.

9. The restraint of claim 1, further comprising side rails attached to and extending upwardly from edges of said foot plate to form a lower profile side railing to retain the foot on said foot plate.

10. The restraint of claim 1, wherein said foot plate is planar.

11. The restraint of claim 1, wherein said means for attaching said foot plate to the foot comprises at least one strap with hook and loop fastening means positioned on said foot plate to secure said foot plate to the foot.

12. The restraint of claim 1, further comprising a first fastener element positioned atop and attached to said foot plate, said first fastener element in communication with said foot plate and said lifting member.

13. The restraint of claim 12, wherein said first fastener element includes a loop fastening element.

14. The restraint of claim 12, wherein said first fastener element is elongated, longitudinal, and positioned in about the middle third portion of said foot plate, and extending from about a midsection of said foot plate longitudinally toward a distal end of said foot plate.

15. The restraint of claim 1, wherein said lifting member has a triangular-shaped cross section.

16. The restraint of claim 1, further comprising a means for fastening said lifting member to said foot plate.

17. The restraint of claim 1, wherein a plane of said lifting member and said foot plate create an angle varying from about 0 degrees to 30 degrees.

18. The method for treatment of recalcitrant plantar fasciitis comprising the steps of:

placing a lifting member on a foot plate;

strapping said foot plate to a bottom of a foot; and

varying a degree of dorsiflexion of metatarsalphalangeal joints by placing differently sized said lifting members on said foot plate;

wherein said lifting member fixedly positions toes of the foot at a greater slope than the generally planar underside of the foot.
