This invention pertains to foot massaging devices, and more particularly to such devices that an individual uses in an upright position to relieve foot discomfort.
The plantar fascia is a flat band ligament that connects the heel bone to the toes and supports the arch of the foot. When the plantar fascia becomes irritated or swollen (condition known as plantar pasciitis), pain is produced in the bottom of the foot near the heel. It is postulated that when the plantar fascia is irritated and suddenly stretched, severe pain is produced, (between 8 and 10 on a 10 point pain scale). If the plantar facia is relaxed and allowed to rest and then slowly stretched, less pain is produced, (between 2 to 4 on a 10 point pain scale).
When sleeping or resting horizontally, the plantar fascia can relax. Unfortunately, 7 to 9 nine hours of rest with the feet horizontal on a bed is an insufficient rest period for irritated plantar fascia. Although the heel pain may subside when laying horizontally, when standing or walking after resting, the pain can be very severe.
To reduce irritation and severe pain, suffers of plantar fasciitis sometimes wear special foot boots with high arches when sleeping. The foot boots are worn when sleeping so the user may walk to the rest room at night. Unfortunately, such boots are uncomfortable and interfere with the user's sleep.
What is needed is a device that treats severe foot pain that occurs when an individual who suffers with plantar fasciitis stands after resting horizontally. What is also needed is a device that does not interfere with the user's sleep.
Disclosed herein is a foot pillow designed to be used by an individual who has plantar fasciitis and suffers with severe heel or foot pain when the individual stands after resting horizontally. The foot pillow includes a square or rectangular body with a flat bottom surface and a dome or conical-shaped top surface with thinner perimeter edges. The foot pillow is made of elastic foam sufficient size to allow the user to stand in place and repeatedly lift and press both feet into the top surface. The elastic foam is configured to resiliently compress under the foot. When the foot is lifted, the area of the body under the foot expands and returns to its original position.
The body is thicker at or near its center axis. The body may be conical or wedge shaped with at least one downward diagonal surface. The diagonal surface intersects with a narrow perimeter edge. The body at its center axis is sufficiently thick to support the user's arch on his or her foot when standing near or at the center axis. When foot is moved outward over the body, the pillow's thickness is reduced thereby providing less arch support.
Using the above pillow, a method for reducing heel pain by an individual suffering with plantar fasciitis after resting horizontally is described that requires the individual to place the above described foot pillow on the floor next to the bed or couch, standing on the pillow with both feet at or near the pillow's center axis where the pillow is thicker, and then repeatingly walk in place over the foot pillow for 1 to 4 minutes and gradually moving the feet towards the pillow's narrow perimeter edge, and then before walking directly over the floor.
A foot pillow 10 designed to be used by an individual who suffers with foot pain that occurs when the individual stands after resting horizontally. The pillow 10 is a square or rectangular structure with a flat bottom surface 12 and a dome or conical shaped top surface 16. The pillow 10 is made of elastic polyurethane foam sufficient size to allow the user to stand in place and repeatedly lifting and stepping each foot 90, 95 into the top surface 16. The foot pillow is made of elastic foam designed to resiliently compress under the foot. When the foot 90, 95 is lifted, the pillow area under the foot expands and returns to its original position as shown in
In the embodiment shown, the body 11 has a square or rectangular bottom surface 12 that measures fourteen to twenty-four inches wide and fourteen to twenty-four inches long. It should be understood that the bottom surface 12 of the body 11 may be circular or oval. The thickness of the pillow 10 at the center axis 17 is approximately 4 to 10 inches. The section of the top surface 16 near the center axis 17 is convex. The diagonal section 18 of the top surface 16 that extends from the center axis 17 to the perimeter edge 14 is aligned 20 to 30 degrees from the bottom surface 12. The outer perimeter edge 14 of the pillow 10 are approximately 1 inch thick.
The pillow 10 has a firmness or compression rating between IFD 10 to IFD 30. The density of the pillow 10 is between 1 to 5 lb./cubic ft.
Using the above pillow 10, a method for treating heel pain that occurs when walking or standing after a person with plantar fasciitis has been resting horizontally is taught.
The method includes the step of selecting the above describe foot pillow 10, placing the foot pillow 10 on the floor 99 adjacent to the bed or couch 80 with the bottom surface 12 facing downward the top surface 16 facing upward. When the user who has been resting horizontally wants to stand, she places both feet 90, 95 on the top surface 16 near the pillow's center axis 17 and stands. The user then repeatedly walks in place over the pillow 10 lifting and stepping each foot 90, 95 into the top surface 16 as shown in
In compliance with the statute, the invention described has been described in language more or less specific on structural features. It should be understood however, that the invention is not limited to the features shown, since the means and construction shown, comprises the preferred embodiments for putting the invention into effect. The invention is therefore claimed in its forms or modifications within the legitimate and valid scope of the amended claims, appropriately interpreted under the doctrine of equivalents.
