JP7056971B2 - Socks for foot skeleton correction - Google Patents

Description

The present invention relates to socks for foot skeleton correction, and more specifically to foot skeleton correction socks used for foot correction / treatment.

As an example of this type of conventional technique, Patent Document 1 discloses a sock-type supporter for correctly correcting inner thigh walking, outer crotch walking, and walking posture. This sock-type supporter partially contains a band-shaped stretch fabric for fixing the ankle metatarsophalangeal joint (Lisfranc joint) and ankle part, and the band-shaped stretch fabric contains the ankle metatarsophalangeal joint. The area around the toes and the area extending downward from the ankle to the ankle on the opposite side around the sole of the foot are formed. By wearing this sock-type supporter and fixing the ankles (and ankles) and insteps (ankle metatarsophalangeal joints), we are trying to correct the lifestyle of inner crotch walking, outer crotch walking, and walking posture. There is.

Further, in Patent Document 2, a plurality of non-stretchable elasticitys are provided in order to correct the posture of the foot so that the weight is mainly applied to the ball of the sole when the foot is worn and walked and the sole touches the ground. A sock is disclosed in which a region is provided and the other region is an elastic region. By wearing these socks and correcting the foot so that it puts a lot of weight on the ball of the sole when the sole touches the foot while walking, it creates a state in which the ankle joint is continuously corrected, and the knee and knee. I am trying to reduce, eliminate, and prevent pain in each of my lower back.

Japanese Unexamined Patent Publication No. 2019-123952 Japanese Patent No. 4654340

As described above, in the sock-type supporter of Patent Document 1, the stretch fabric laterally surrounds the tip of the foot including the metatarsophalangeal joint of the foot, and extends downward from the medial malleolus to go around the sole of the foot. By forming to the fruit, the ankle (and ankle) and the instep (foot metatarsophalangeal joint) are fixed, and in the socks of Patent Document 2, the foot is laterally surrounded by a non-stretchable member. As a result, the ankle joint is fixed, and both of them limit the movement of the ankle joint.

These are correction methods that keep the ankle joint in a static and stable state so that it does not move, similar to the general procedure of resting and fixing the affected area with a cast or supporter when the foot is injured by orthopedic surgery. Therefore, if a long period of time has passed while wearing the sock-type supporter of Patent Document 1 or the socks of Patent Document 2, the function of the proprioceptor is deteriorated due to the restriction of joint movement, and the plantar dorsiflexion of the ankle joint is caused. The limitation may reduce the milking function (blood circulation) of the lower limb muscles and delay tissue repair. In addition, joint contracture and muscular atrophy may occur after fixation removal.

Therefore, a main object of the present invention is to provide socks for foot skeletal correction that are effective for foot correction and treatment.

In order to achieve the above-mentioned object, the sock main body and the first supporter portion having less elasticity than the sock main body are provided, and the first supporter portion extends from the upper part of the inner malleolus to the lower part of the distance projection on the inner malleolus and the sole of the foot. Foot skeletal correction socks are provided that are formed through and corresponding to the lateral side of the cuboid bone.

The distance-distance projection is the origin of the function of human erect bipedalism, which supports most of the pressure of the entire human skeleton and distributes the force to the entire foot, such as standing, walking, running, jumping, and kicking. Generates the driving force of movement. In order for the foot to function sufficiently for human standing walking, it is important to maintain the upper surface of the distance-mounting projection at an appropriate angle (about 90 degrees) with respect to the long axis of the foot.

In the present invention, when the foot skeletal correction sock is worn, the first supporter portion having low elasticity is the distance projection of the medial malleolus and the sole of the foot from above the medial malleolus (around the transition from the calcaneal tendon to the gastrocnemius muscle). It functions like tapping through the bottom to the outside of the cuboid bone. At this time, since the first supporter portion supports the medial malleolus, the talus, and the talus so as to press them toward the lateral malleolus, the upper surface of the talus is maintained at an appropriate angle with respect to the long axis of the foot, and the talus is maintained. Can be placed in the normal position on the talus process, and the medial malleolus and thus the tibia can be kept in the normal position. As a result, the foot can fully fulfill the role of the placement system, the center of gravity can be placed on the talus process during walking, the subtalar joint is stable, and the person can walk in the correct posture. In addition, the first supporter portion does not surround the foot in the lateral direction and is not formed in an annular shape. That is, the first supporter portion is formed on the inner malleolus and the sole of the foot, but is hardly formed on the instep and not on the outer malleolus. Therefore, the movement of the ankle joint is not restricted by the first supporter portion, and the ankle joint can be comfortably flexed to the plantar dorsiflexion, whereby the function of the fibula can be improved. In this way, the first supporter portion allows the ankle joint to move smoothly while keeping the foot skeleton in the correct position. In other words, by substantially taping the necessary part in the first supporter part, the correct positional relationship of the feet can be maintained, movements such as walking can be stabilized, unstable elements during movements can be reduced, and dynamic stability can be achieved. It can enhance the sex. When the socks for foot skeletal correction according to the present invention are worn during acute trauma such as sprained ankle, joint movement such as plantar dorsiflexion of the ankle joint is not restricted, so that the force to recover (encapsulation force / natural healing force) ) Can be maintained. Therefore, it is possible to suppress a decrease in proprioceptor function and a decrease in milking function (blood circulation), and further suppress joint contracture and muscular atrophy after fixation removal, so that the healing period can be shortened.

Preferably, a second supporter portion having a smaller elasticity than the sock body is further included, and the second supporter portion is formed in a portion corresponding to the heel so as to wrap the heel. In this case, when the socks for correcting the foot skeleton are worn, the second supporter portion having a small elasticity functions in the same manner as the taping of the heel that wraps the heel. Therefore, the second supporter portion can stabilize the position of the heel in the foot portion and fix the heel in the correct position. As a result, movements such as walking can be made more stable, and dynamic stability can be further enhanced.

It also preferably further includes a third supporter portion that is less elastic than the sock body, the third supporter portion passing from above, medially and inferior to the first metatarsophalangeal joint to the lateral side of the fifth metatarsal bone. It is formed in the portion corresponding to the above, and the portion corresponding from the lateral side of the fifth metatarsal bone to the medial side of the cuneiform bone along the anterior end portion of the first supporter portion. In this case, when the foot skeletal correction socks are worn, the third supporter portion, which has low elasticity, passes from above the first metatarsophalangeal joint to the lateral side and the lower side to the lateral side of the fifth metatarsal bone. And, it functions in the same manner as tapping from the lateral side of the fifth metatarsal bone to the medial side of the wedge bone along the first supporter portion. Therefore, the third supporter portion can press the vicinity of the first metatarsal joint to the lateral side (second toe side), and can suppress the varus of the first metatarsal bone and the valgus of the mother toe. Therefore, the valgus can be improved. As a result, movements such as walking can be further stabilized, and dynamic stability can be further enhanced.

More preferably, the elasticity of the first supporter portion is smaller than the elasticity of the second supporter portion and the third supporter portion. In this case, a preferable taping force is given to each part of the foot whose position is corrected by the first supporter portion, the second supporter portion, and the third supporter portion, and the foot skeleton can be kept in an appropriate position.

Preferably, the first supporter portion has a double structure, and the second supporter portion and the third supporter portion have a single structure. In this case, the elasticity of the first supporter portion can be easily made smaller than the elasticity of the second supporter portion and the third supporter portion.

"Stretchability" refers to the property of expanding and contracting, and for example, "small elasticity" means that the degree of expansion and contraction is small.

Regarding the foot, the "medial side" refers to the side of the first toe (mother toe) in the lateral direction, and the "outer side" refers to the side of the fifth toe (small toe) in the lateral direction.

According to the present invention, socks for foot skeleton correction that are effective for foot correction / treatment can be obtained.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

With reference to FIGS. 1 to 5, the foot skeleton correction sock 10 is a high sock type sock type supporter that covers up to below the knee when worn, and is a sock body 12, a first supporter portion 14, and a second supporter portion. 16 and a third supporter unit 18.

The sock body 12 is made of, for example, a mixed fabric of cotton and polyester, and the first supporter portion 14, the second supporter portion 16 and the third supporter portion 18 are made of, for example, nylon. The elasticity of the first supporter portion 14, the second supporter portion 16, and the third supporter portion 18 is smaller than the elasticity of the sock body 12. Further, the first supporter portion 14 has a double structure, and the second supporter portion 16 and the third supporter portion 18 have a single structure. As a result, the elasticity of the first supporter portion 14 becomes smaller than the elasticity of the second supporter portion 16 and the third supporter portion 18.

The sock body 12 is formed in the foot skeleton correction sock 10 at a position other than the first supporter portion 14, the second supporter portion 16, and the third supporter portion 18.

Also referring to FIGS. 6 and 7, the first supporter portion 14 extends downward from above the medial malleolus a (ie, around the transition from the calcaneal tendon to the gastrocnemius muscle) through the medial malleolus a. The 14a, the outer support portion 14b extending downward from the lateral side of the cuboid bone b, passing under the distance projection d of the sole c, and connecting the lower end portion of the inner support portion 14a and the lower end portion of the outer support portion 14b. Includes lower support section 14c. As a result, the first supporter portion 14 is formed in a portion corresponding to the outer side of the cuboid bone b from above the inner malleolus a, passing below the distance projection d of the medial malleolus a and the sole c.

The second support portion 16 is located behind the first supporter portion 14, is connected to the rear portions of the inner support portion 14a, the outer support portion 14b, and the lower support portion 14c, and extends from the heel e to the center of the outer fruit f. Formed to cover. As a result, the second supporter portion 16 is formed in a portion corresponding to the heel e so as to wrap the heel e.

The third supporter portion 18 includes an anterior support portion 18a extending from above, medially and inferior to the lateral side of the fifth metatarsal bone h from above the first metatarsal joint g, and the lateral end portion of the anterior support portion 18a. The posterior support portion 18b extending from the first supporter portion 14 to the medial side of the cuneiform bone i along the anterior end portion thereof is included, and is formed in a substantially V shape. As a result, the third support portion 18 becomes a portion corresponding to the lateral side of the fifth metatarsal bone h from the upper side to the medial side and the lower side of the first metatarsophalangeal joint g, and the first supporter part 14. It is formed along the corresponding portion from the lateral side of the fifth metatarsal bone h to the medial side of the cuneiform bone i.

In this way, in the front view of the foot skeleton correction sock 10, the first supporter portion 14 is formed in a substantially J shape. The first supporter portion 14 is sandwiched between the rear support portion 18b of the third supporter portion 18 and the second supporter portion 16 from the front and back. Further, none of the first supporter portion 14, the second supporter portion 16, and the third supporter portion 18 is formed so as to cross the front surface (the portion corresponding to the instep j) of the sock 10 for foot skeleton correction. .. That is, on the front surface of the foot skeleton correction sock 10, the sock body 12 is formed so as to be continuously connected from the upper end portion to the lower end portion of the foot skeleton correction sock 10.

According to the foot skeletal correction socks 10, when worn, the first supporter portion 14, which has low elasticity, is located above the inner malleolus a (around the transition from the calcaneal tendon to the peritoneal muscle) to the medial malleolus a and the sole c. It functions in the same manner as tapping to the lateral side of the fifth metatarsal bone h through the lower part of the distance-carrying process d. At this time, since the first supporter portion 14 supports the inner malleolus a, the talus k, and the talus d so as to press them toward the outer malleolus f, the upper surface of the talus d is appropriate for the long axis P of the foot. The talus k can be placed in a normal position on the talus process d, and the medial malleolus a and thus the tibia l can be kept in a normal position. As a result, the foot can sufficiently play the role of the placement system, the center of gravity can be placed on the talus process d during walking, the subtalar joint m is stable, and the person can walk in the correct posture. Further, the first supporter portion 14 does not surround the foot in the lateral direction and is not formed in an annular shape. That is, the first supporter portion 14 is formed on the inner malleolus a and the sole c, but is hardly formed on the instep j and not on the outer malleolus f. Therefore, the movement of the ankle joint is not restricted by the first supporter portion 14, and the ankle joint can be comfortably flexed at the plantar dorsiflexion, whereby the function of the fibula n can be improved. In this way, the first supporter portion 14 can smoothly move the ankle joint while keeping the foot skeleton in the correct position. In other words, by substantially taping the necessary part with the first supporter portion 14, the correct positional relationship of the legs can be maintained, movements such as walking can be stabilized, unstable elements during movements can be reduced, and dynamics can be achieved. Stability can be increased. When the socks 10 for foot skeletal correction are worn during acute trauma such as sprained ankle, joint movement such as plantar dorsiflexion of the ankle joint is not restricted, so the force to recover (encapsulation force / natural healing force) is maintained. can. Therefore, it is possible to suppress a decrease in proprioceptor function and a decrease in milking function (blood circulation), and further suppress joint contracture and muscular atrophy after fixation removal, so that the healing period can be shortened.

When the foot skeleton correction socks 10 are worn, the second supporter portion 16 having a small elasticity functions in the same manner as the taping of the heel e that wraps the heel e. Therefore, the second supporter portion 16 can stabilize the position of the heel e in the foot portion and fix the heel e in the correct position. As a result, movements such as walking can be made more stable, and dynamic stability can be further enhanced.

When the foot skeletal correction socks 10 are worn, the third supporter portion 18 having a small elasticity passes from the upper side to the medial side and the lower side of the first metatarsophalangeal joint g to the lateral side of the fifth metatarsal bone h. It functions in the same manner as tapping from the lateral side of the fifth metatarsal bone h to the medial side of the wedge-shaped bone i along the first supporter portion 14. Therefore, the third supporter portion 18 can press the vicinity of the first metatarsal joint g laterally (to the second toe side), and the varus of the first metatarsal bone o and the valgus of the mother toe. Can be suppressed, so the hallux valgus can be improved. As a result, movements such as walking can be further stabilized, and dynamic stability can be further enhanced.

By making the elasticity of the first supporter portion 14 smaller than the elasticity of the second supporter portion 16 and the third supporter portion 18, the position is determined by the first supporter portion 14, the second supporter portion 16, and the third supporter portion 18. A favorable taping force is given to each part of the foot to be corrected, and the foot skeleton can be kept in an appropriate position.

By making the first supporter portion 14 a double structure and making the second supporter portion 16 and the third supporter portion 18 a single structure, the elasticity of the first supporter portion 14 can be easily increased to the second supporter portion 16 and the third supporter. It can be made smaller than the elasticity of the portion 18.

In the above-described embodiment, the case where the foot skeleton correction sock 10 includes the first supporter portion 14, the second supporter portion 16, and the third supporter portion 18 has been described, but is not limited thereto. The sock for foot skeleton correction according to the present invention may include at least the first supporter portion 14, and may include at least one of the first supporter portion 14 and at least one of the second supporter portion 16 and the third supporter portion 18. It may be included.

In the above-described embodiment, the same material is used for the first supporter portion 14, the second supporter portion 16, and the third supporter portion 18, the first supporter portion 14 has a double structure, and the second supporter portion 16 and the third supporter portion are formed. By making 18 a single structure, the elasticity of the first supporter portion 14 is made smaller than the elasticity of the second supporter portion 16 and the third supporter portion 18, but the elasticity is not limited to this. The first supporter portion 14, the second supporter portion 16 and the third supporter portion 18 have a single structure, and the fabric of the first supporter portion 14 has less elasticity than the fabric of the second supporter portion 16 and the third supporter portion 18. By using the above, the elasticity of the first supporter portion 14 may be made smaller than the elasticity of the second supporter portion 16 and the third supporter portion 18.

Further, the elasticity of the first supporter portion 14, the second supporter portion 16 and the third supporter portion 18 may be the same as long as they are smaller than the elasticity of the sock body 12.
