GARMENT FOR IMPROVED FOOT AND LEG ALIGNMENT AND IMPROVED CIRCLUATION

Abstract

A garment for a human lower extremity with variable elasticity in the toe, heel and body of the garment is provided. A band of decreased elasticity is incorporated into the body of the sock extending from the toe area to the proximal end of the garment. A novel method for applying the sock includes twisting the garment, which results in providing targeted neuromuscular stimulation by the band to the location on the human lower extremity that the user positions the band over, thus improving alignment, gait, balance, circulation, and decreasing swelling and injury. Twisting of the garment also selectively increases a level of compression applied by the garment at said location relative to a level of pressure applied at adjacent locations. The location of the band and amount of compression generated by the garment is customizable by the wearer, depending upon the degree of twist chosen by the wearer.

DETAILED DESCRIPTION

[0029] As used herein, the terms device and garment are interchangeable. In the illustrated embodiments, the device or garment is a sock.

[0030] FIGS. 1-13 show one embodiment of a garment, specifically a sock or stocking 10. The sock 10 can optionally be made of an elastic knitted material (e.g., cotton or synthetic material) with a denser knit at the toe 22 and heel 23 portions of the sock 10. The purpose of this knit is to provide an anchor for the sock 10 that will remain in place when the sock is twisted or rotated. The toe 22 and heel 23 portions can optionally be thicker than the body (e.g., the remaining portion) 21 of the sock 10. In another embodiment, the toe 22 and heel 23 portions can optionally be thinner than the body 21 of the sock 10. The body 21 of the sock 10 can optionally be an elastic knit with decreased density between 10-50%, and increased elasticity between 10-50%, as compared to the density and elasticity of the toe 22 and heel 23 portions. However, in other embodiments, the body 21 of the sock 10 can have other density and elasticity values relative to the toe 22 and heel 23 of the sock 10. The sock 10 material may optionally contain metal ions and/or have properties that regulate skin temperature and/or wick sweat away from the skin. In one embodiment, the toe 22 and heel 23 portions can optionally include bumps or material that grips the skin to inhibit shifting of the toe 22 and heel 23 portions from engagement with the toes T and heel H of the foot F. Such bumps can be similar to the bumps 20A discussed below.

[0031] A band 20 (e.g., a single band) can optionally be incorporated into the body 21 of the sock 10 (e.g., in a seamless manner), such that the band 20 extends from a distal end (e.g., toe portion 22) of the sock 10 to a proximal end (e.g., band 24 at the ankle A in FIG. 11, band 24 at the calf C in FIGS. 6-7, and band 24 at the thigh TH in FIG. 12) of the sock 10. In another embodiment, the band 20 can be incorporated into the body 21 of the sock 10 in a seamed manner. The band 20 can have a width W that can be between one and three inches. However, in other embodiments, the width W of the band 20 can be greater or smaller than these values. In some embodiments, the width W of the band 20 can optionally vary along the length of the band 20. In other embodiments, the width of the band is generally constant along the length of the band 20. In one embodiment, the band 20 is optionally made of a 10-50% more tightly woven knit than the body 21. However, in other embodiments, the band 20 can have other suitable knit densities. In some embodiments, the band 20 is optionally made of the same material as the body 21 of the sock 10, but only differs in the knit density. In another embodiment, the material of the band 20 is different from the material of the body 21 of the sock. The band 20 can optionally extend from the toe portion 22 to a proximal end 24 of the sock 10. The band 20 can in one embodiment have a generally constant width W along its length. In another embodiment, the band 20 can optionally have a variable width W depending upon the muscles to be stimulated in the foot F and leg L. Advantageously, the band 20 is strategically located to provide targeted neuromuscular stimulation, which mimics the effect of skin taping techniques, but in a dynamic garment worn on the foot F and leg L. In one embodiment, shown in FIG. 11, the sock 10 is relatively short and extends from the user's toes T to their ankle A. In another embodiment, shown e.g. in FIGS. 6-7, the sock 10 has a relatively intermediate length (as compared to the short and long versions) and extends from the user's toes T to their calf C. In still another embodiment, shown in FIG. 12, the sock 10 is relatively long (as compared to the short and intermediate versions) and extends from the user's toes T to their thigh TH.

[0032] In another embodiment, the sock 10 can optionally include an elastomeric material, such as elastane or silicone, where the toe 22 and heel 23 are constructed to conform to the shape of the toes T and heel H to anchor the sock 10 in these locations. The band 20 that extends from the proximal end to the distal end of the sock 10 can optionally be incorporated into the sock 10 and be of an elastomeric material with 25-75% increased resistance to stretch as compared to the body 21 of the sock 10. In other embodiments, the elastomeric material can have lower or higher increased resistance to stretch when compared to the body 21 of the sock 10. The band 20 can optionally be of variable width W depending upon which muscles are to be stimulated, and can be strategically located to provide targeted neuromuscular stimulation which mimics the effect of skin taping techniques, but in a dynamic garment worn on the foot F and leg L.

[0033] Advantageously the sock 10 provides compression of the soft tissue of the lower extremity by way of the elastic nature of the fabric of the sock 10, and can be further augmented by optionally twisting the garment during application over the extremity (e.g., so that the band 20 extends in a spiral manner along the leg L). In one embodiment, unlike existing compression stockings, the sock 10 can apply a minimal amount of compression (e.g., about 1 mmHg) when pulled onto the user's leg, which facilitates the easy donning and doffing of the sock 10, as compared to existing compression stockings. The user can increase the compression provided by the sock 10 at one or more locations targeted by the user by twisting the fabric of the sock 10 at said locations (relative to adjacent locations). Such twisting of the sock 10 can apply an increased pressure to the soft tissues at said locations in the range of about 5 mmHg to about 40 mmHg. Accordingly, the level of compression applied by the sock 10 is provided by the amount of twist applied to the sock 10 while on the user's leg, not by a pre-compression of the garment due to a tightness of the knit of the garment prior to donning the garment.

[0034] FIG. 1 is a schematic diagram showing a position of the sock 10 prior to application to the left foot F as seen from the lateral aspect or side. The sock 10 can be applied with the heel 23 facing outward or away from the user's toes T. As shown in FIG. 4, the band 20 can extend from a distal lateral dorsal side of the toe 22 of the sock 10 for a user with excessive pronation and can include a viscoelastic material with increased resistance to stretch as compared to the body 21 of the sock 10. In one embodiment, the band 20 can optionally include bumps 20A or material that grips the skin for the purpose of neuromuscular stimulation and/or proprioception. The bumps can optionally be made of the same material as the band 20, but provide raised off the surface of the band 20 to contact the skin. In another embodiment, the bumps can optionally be made of a different material (e.g., a viscoelastic material, such as silicone) than the material of the band 20. The material of the sock 10 at the toe 22 and heel 23 can have decreased elasticity as compared to the body 21 of the sock 10 to maintain position of the sock 10 on the toe T and heel H of the user's foot F during application and use.

[0035] FIG. 2 shows the sock 10 pulled onto the toes T of the foot F. The toe portion 22 of the sock 10 engages the toes T and the band 20 is disposed on the dorsal and lateral sides of the foot F, and the heel portion 23 of the sock 10 is on the dorsal side of the foot F. The sock 10 is then twisted counterclockwise as shown in FIG. 3, to reposition the band 20 and heel portion 23 to the plantar side of the foot F while the toe portion 22 remains in place and secured to the toes T of the user's foot F; such twisting also increases a compression force provided by the sock 10 between the toe portion 22 and heel portion 23. Once repositioned from the dorsal side to the plantar side, the band 20, the band 20 can extend across the sole of the foot F as shown in FIG. 4. As shown in FIG. 4, a first portion 20a of the band 20 extends from a lateral side L1 at the toe 22 of the sock 10 to a medial side M1 of the foot F over the arch. Twisting the sock 10 in a specific direction advantageously provides 3-dimensional neuromuscular stimulation to improve leg alignment and proprioception to improve (e.g., create a more normal) gait and muscle efficiency, decrease muscle fatigue and inhibit injury. Twisting the sock 10 also advantageously provides customized or targeted compression, as desired by the user, to decrease swelling and improve circulation in the foot F and leg L. After applied to the toes T, the sock 10 is twisted 180 degrees until it engages on the heel H. The sock can then be twisted between zero and 360 degrees as it is pulled up the leg L to vary the level of compression applied to the leg L as well as to position the band 20 as desired to provide for targeted neuromuscular stimulation. In another embodiment, the sock 10 can instead be rotated clockwise (e.g., where there is excessive pronation of the right foot F).

[0036] With reference to FIG. 5, the heel 23 of the sock 10 is engaged on the wearer's heel H. The band 20 which has the first portion 20a extending medially in FIG. 4, extends up to a second portion 20b of the band 20 adjacent the user's ankle A. The wearer can choose the location of the band 20 on the leg L as the sock 10 is pulled up the leg L by degree the sock is twisted. This degree of twist also customizes the amount of compression provided by the sock 10 on the leg L to the wearer's preference. FIG. 6 shows the sock 10 pulled up the leg L with the band 20 extending in a twisting manner from the second portion 20b up to a third portion 20c of the band 20 generally adjacent the user's calf C with a high degree of twist. FIG. 7 shows the sock 10 from the medial side of the leg L, which shows the first portion 20a of the band 20 extending from the medial side of the foot F upward toward the ankle A and then twisting toward the third portion 20c of the band 20 generally adjacent the user's calf C. The fabric at the top 24 of the sock 10 can optionally include an elastic fabric and can optionally grip the skin. If the wearer chooses relatively less compression by twisting the band 20 by a relatively lower amount, the placement of the second and third portions 20b, 20c of the band 20 can be disposed more laterally on the leg L, as shown for example in FIG. 8.

[0037] In the embodiment illustrated in FIGS. 1-8 and discussed above, the sock 10 was designed for a wearer with excessive pronation. In another embodiment, if a wearer has excessive supination, the sock 10 can optionally have the band 20 located on the opposite side, as in FIG. 9, so that it extends from the medial side M2 of the foot F at the toe 22 of the sock 10 to the lateral side L2 of the foot F along the plantar side of the foot F to provide neuromuscular stimulation, 3-dimensional tension and proprioception. The band 20 can extend from a distal medial 20d portion to the plantar lateral portion 20e to improve the malalignment. As the sock 10 is further pulled up the leg L in FIG. 10, the plantar lateral portion 20e transitions onto the dorsal side of the foot F and then transitions to a leg portion 20e that is twisted around the user's leg L toward the band 24 at the proximal end of the sock 10. The degree of twist and resulting location of neuromuscular stimulation and compression is customized by the wearer by twisting the sock 10 to position the band 20 as desired along the user's leg L.

[0038] The sock 10 is optionally available in 3 lengths: calf-high as in FIGS. 6,7 and 8, ankle-high as in FIG. 11 and thigh-high as in FIG. 12. In the ankle-high version, neuromuscular stimulation, improved proprioception and compression are isolated to the foot F and ankle A, where it can advantageously aid a wearer with mild increased pronation and/or mild foot swelling. The calf-high length version of the sock 10 can advantageously aid a wearer with moderate to severe increased pronation and/or more significant foot/leg swelling. The thigh-high length version of the sock 10 can advantageously aid a wearer with moderate to severe pronation and/or significant foot/leg swelling in and ambulatory and sedentary individual due to the increased surface area provided in the device for neuromuscular stimulation, proprioception and compression.

[0039] In one embodiment, the sock 10 can be used to treat existing malalignment of the foot and/or leg, as described above, as well as to reduce or inhibit swelling by improving blood circulation in the user's legs. In another embodiment, the sock 10 can be used to inhibit such problems from developing. In still another embodiment, the sock 10 can be used as an athletic accessory to enhance performance by facilitating blood circulation in the user's legs and provide neuromuscular stimulation, proprioception and compression as desired by the user.
