Embodiment

[0069] 1. An assembly for supporting the plantar fascia of a wearer, said assembly comprising:

[0070] a footplate contoured to conform to the arch area of ​​the wearer's foot, the footplate including a contoured shape including a medial arch and a lateral arch;

[0071] An adjustable strap adapted to maintain the footrest plate proximal to the arch area during use, wherein the assembly is bipedal.

[0072] 2. The assembly of embodiment 1, wherein the footplate comprises a heat-extensible material.

[0073] 3. The assembly of embodiment 1, wherein the footplate comprises a shape memory material.

[0074]4. The assembly of any one of the preceding embodiments, wherein the footbed has a continuous thickness of at least 0.04 inches and no greater than 0.06 inches.

[0075] 5. The assembly of any one of the preceding embodiments, wherein the adjustable strap includes a dimple, and wherein the footrest remains in the dimple during use.

[0076] 6. The assembly according to any ...

[0093] testing method

[0094] Flexure resistance

[0095] This test provides a means of determining the force (pound-force (lbf)) required to displace a formed footplate a specified distance (in inches).

[0096] Place the sample foot plate on the TCD225 Series Digital Force Testers (available from Ametek Corporation, Largo, Florida). Apply force in a direction generally normal to the center of the sample foot plate. The force required to displace the sample over a distance interval is recorded.

[0097] Sample Preparation

[0098] Sample footplates were produced by injection molding the specific materials listed in Table I (below) in a mold to provide figure 2 The outline shown. Each footplate has a continuous thickness of about 0.04 inches. Three samples of each example footbed construction (F1, F2, F3, F4, F5) were tested according to the method above.

Abstract

Thin, contoured footplates that maintain tension in the plantar fascia without causing undue discomfort to the user are suggested for the treatment of plantar fasciitis and other heel pain. The footplate may be bipedal and thus serve to support either the left plantar fascia or the right plantar fascia. The footplate may be used in assemblies for securing the footplate to a wearer's foot, as well as in systems for recurrent treatment of plantar fasciitis and other heel pain.

Description

Background technique [0001] Plantar fasciitis is inflammation of the plantar fascia near its attachment point to the calcaneus, or the front surface of the heel bone. The plantar fascia becomes wider and thinner as it runs longitudinally over the bottom of the foot, eventually dividing into five processes near the heads of the metatarsal bones, each process corresponding to one of the five toes. As the strongest ligament in the body, the purpose of the plantar fascia is to protect the soft muscles and tissues on the bottom of the foot from injury, as well as to help maintain the integrity of the foot structure itself. If the fascia is stretched or strained, the arch area and the area around the calcaneus can become weak and swollen. This inflammation is called plantar fasciitis and is usually painful from the heel through the entire arch of the foot to the Achilles tendon. Patients suffering from this condition often have a relatively tight and inflexible Achilles tendon, so...
