Definitions
- This invention relates to orthotic devices and is particularly concerned with resiliently flexible orthotic devices which are designed to provide functional support for the foot without inhibiting the functional motion of the foot.
- the invention will primarily be described in relation to inserts for footwear, particularly performance footwear such as dancing, ballet and athletic shoes, however it also extends to orthotic devices which are fitted directly to the foot or indirectly with the use of some form of containment such as hosiery, bandages, strapping or layered materials.
- a "high arched" foot is of paramount importance for a ballet dancer.
- the bones of the foot are locked together and the foot is rigid.
- This rigidity provides the stability necessary to maintain an "en pointe” (or tiptoe) dancing position.
- This position also necessitates strengthening and maintaining the strength of the muscles both in the leg and the foot.
- Dancers are not permitted to dance "en pointe” until the foot and the leg muscles are strong enough to ensure stability, control and safe dancing in this position.
- the "arched" foot look is also considered aesthetically pleasing and all dancers strive to enhance the "look" of the foot.
- This invention was inspired out of the necessity to treat dancers and other athletes who had developed serious injuries due to the combination of unprotected repetitive activity and poor "sustained" foot function - often due to muscle fatigue.
- an orthotic device which comprises a substantially rigid moulded sheet of resiliently deformable plastics material which provides continuous contact with the arch of the foot whether the foot is flat or pointed, after it has initially been moulded to substantially conform with the shape of the arch of the foot.
- the orthotic device is formed from a plastics material which is moulded by heat, microwaves or other appropriate means to produce a high arch profile.
- the plastics material is chosen from the range of plastics having a shape "memory" property which permits it to be flattened out under applied pressure and then to return to its original memorized configuration once the applied pressure has been removed.
- the sheet plastics material should also be such as to provide a firm yet flexible contact with the arch of the foot.
- the sheet will suitably range in thickness from less than one millimetre to a few millimetres, preferably approximately one millimetre, and may comprise several sheets laminated together.
- the resiliently flexible orthotic device to be moulded enables it to be shaped or reshaped to the arch contours of the particular foot it is to be used with by a simple process such as direct heating using a hair dryer or the like or by placing it in a microwave oven.
- a simple process such as direct heating using a hair dryer or the like or by placing it in a microwave oven.
- the device When the device is heated or microwaved, it softens sufficiently to enable shaping. As it hardens, it memorises the shape into which it has been formed.
- the preferred plastics material is the product sold under the trade name QuikformTM by Acor Orthopaedic, Inc. of the U.S.A. This product has a moulding temperature of around 200°F.
- the function of the resiliently flexible orthotic device is threefold, viz:
- the orthotic device can be made to fit the template of the performance footwear it is to be used with and suitably includes a portion which enables it to be secured to the heel portion of the footwear.
- the orthotic device can be secured with a two way thin adhesive wafer or a thicker velcro® dot to enable transfer between footwear.
- the orthotic device could be strapped directly to the foot or retained within a suitable stocking.
- a multi-layered orthotic device comprising the mouldable sheet of plastics material referred to hereinbefore, sandwiched between a shock absorbent layer and a covering layer.
- the covering layer is intended to lie adjacent the foot of the wearer and the shock absorbent layer is intended to face the sole of the wearer's shoe.
- the shock absorbent layer and the covering layer may also comprise multi layers of the same or different material to increase shock absorbency if required or to provide additional stimulus or comfort to the arch.
- the shock absorbent or base, layer can be manufactured from any conventional shoe insert material commonly used for this purpose.
- these materials are foamed plastics and rubber materials such as polyurethanes and polyisoprenes .
- Particularly preferred are the Poron® Medical Cellular Urethanes. These are engineered, high density, microcellular urethane foam materials designed for use in orthotic and prosthetic applications. Poron® medical materials are mechanically foamed, resulting in excellent thickness tolerance and lot to lot consistency. They will not thin out or take a compression set, and will retain 95% of their original thickness for the life of the product. These materials are excellent shock absorbers. Each of the cells in the material acts like a tiny spring or energy absorber. Coupled with the compression set properties, these materials will not lose their ability to absorb shock over time.
- the preferred Poron® layer used is a split material with a roughened surface, which is laminated to the rest of the other layers, and a smooth surface.
- the smooth surface contacts the insole of the footwear, which allows the orthotic device to coil and recoil with minimal friction.
- Poron® materials are easily cut and fabricated and can be adhered or laminated to a wide range of other materials. Gram for gram, this material is a superior shock absorber and this lightweight quality makes it suitable for use in the invention.
- the covering, or top, layer of the orthotic device is selected from a range of materials having one or more of the following properties:
- the preferred covering is leather.
- Other covers specifically designed for sweaty feet, skin disorders and increased tactile stimulus may also be used.
- the three layers of the orthotic device are preferably adhered together with a commercial adhesive which is commonly used in the footwear industry.
- a particularly preferred adhesive is sold under the trade name Duall 88®.
- the last size and shape of the footwear will determine the dimensional parameters of the multi-layered orthotic device.
- Body weight and the intended activity will determine the thickness of the shock absorbent layer and the covering layer.
- the shock absorbent layer is suitably cut to the dimensions of the full last of the footwear.
- the inner sheet of plastics material is limited in width to the width of the last and limited in length to the length of the inner longitudinal arch. (This dimension is calculated on the length of the last) . This layer is therefore significantly shorter at both ends than the shock absorbent layer and the covering layer.
- the outer covering layer is cut either to the actual dimensions of the last (as with the shock absorbent layer) or 1 mm larger to enable extra shock absorbency to be added at any time if required.
- the flexible characteristic (coil and recoil) of the orthotic device according to the present invention is unique and sets it apart from other insole devices.
- Other insole devices are designed to supply shock absorbency, to carry a medicament (eg. Charcoal odour eaters within the insole) , to restrict foot function or to support the bones of the foot.
- the present orthotic device provides constant contact with the arch, stimulating the skin, nerve endings and the superficial muscles under the foot.
- the flexibly resilient orthotic device is not an arch support as it is designed to allow the foot to be flexible and the characteristics of the device do not provide any extrinsic support to the foot whatsoever.
- the orthotic device will be available as an "off the shelf” purchase, and will be packaged according to the size of the performance footwear. It will preferably be distributed in flat form, with clear instructions and simple diagrams explaining the moulding process.
- Figure 1 is a side cross-sectional view of an orthotic device in an extended configuration
- Figure 2 is a top plan view of the orthotic device show in Figure 1;
- Figure 3 is a partial top perspective of the orthotic device shown in Figures 1 and 2, in an arched configuration
- Figure 4 is a cross-sectional view of the orthotic device shown in the previous Figures in si tu, with in a ballet shoe, and
- Figure 5 is a cross-sectional view of the orthotic device and ballet shoe shown in figure 4 in an "en pointe” configuration.
- Figures 1 and 2 show a multi-layered flexible orthotic device in a form in which it would be purchased or in a form it would assume under a flat foot in performance footwear.
- the orthotic device comprises a shock absorbent layer 10, a mouldable sheet of plastics material 11 and a covering layer 12.
- the shock absorbent layer 10 consists of a 1 mm layer of Poron®, as referred to hereinbefore; the mouldable sheet of plastics material 11 consists of a 1 mm thick insert fabricated from QuickformTM positioned in the arch region only of the orthotic device; and the covering layer 12 consists of a 1 mm thick layer of leather. All layers are adhered together with the adhesive Duall 88®, also previously referred to.
- Figures 1 and 2 illustrate the form the orthotic device takes when it is purchased. Accordingly, in order to transform it into a useable product with a memorized arch configuration as shown in Figure 3, the orthotic device must be subjected to radiant heat or microwave radiation of a sufficient intensity to enable the sheet of plastics material to become mouldable, without adversely affecting the integrity of the covering and the shock absorbent layers.
- One preferred method to achieve this utilizes a hair dryer on high heat.
- the hair dryer is held approximately
- the nozzle of the hair dryer is moved up and down to direct an even flow of hot air to the mouldable sheet of plastics material 11.
- the plastics material typically softens after a few minutes of such treatment.
- the orthotic device is then bent in half so that the undersides face each other, and is rolled to and fro between the hands several times. It is placed topside facing upwards on a flat surface and the central portion is bent into an exaggerated arch by pushing the toe end and the heel end towards each other until they are approximately 2cms apart. This shape is maintained until the orthotic device cools. When completely cool, the orthotic device is placed in the footwear. If required, securement can be achieved using a velcro® fixing or the like under the heel.
- the flexible resilient orthotic device will slide forward and flatten as shown in Figure 4 then recoil when the heel is lifted or weight is transferred to the lateral border of the foot as shown in Figure 5.
- the orthotic device will ensure contact with the arch at all times.
- the orthotic device can simply be reheated as above to reestablish the required arch shape.
