Description

  The present invention relates to a legwear particularly for suppressing knee sway, and more particularly to a legwear useful for O leg control and sports support.

  In elderly women, there are many people with knee pain caused by O leg deformation, which is a problem. Therefore, conventionally, techniques for guiding the knee inward have been proposed.

  For example, Patent Document 1 proposes a tubular knee supporter surrounding a knee joint for correction of varus deformation. This supporter is provided with a band portion which applies a tightening force in a direction in which the calcaneal small head is directed to the inner side of the leg when the main body portion is mounted. Thereby, the rib small head shifted to the outside is pressed inward, and correction of varus deformation is intended.

  Further, Patent Literature 2 and Patent Literature 3 propose crotched clothing that covers from the waist to the upper part of the thigh, which makes it easy to turn the knee inward. The crotched clothing described in Patent Document 2 includes a body part covering from the waist to the upper part of the thigh, and a large adductor muscle covering a site where a large adductor muscle having a stronger tightening force than the body part is located. A support portion and a non-stretchable side patch cloth portion that covers the side of the thigh and is partially adjacent to the large adductor support portion. The crotch garment described in Patent Document 2 extends and contracts along the large adductor muscle in a state where the large adductor muscle support portion is in close contact with the thigh.

  The crotched clothing described in Patent Document 3 includes a main body that covers from the waist to the upper part of the thigh, and a support line that covers a portion where the large adduction muscle is located, which is stronger than the main body. Have. The support line portion is spirally connected from a position corresponding to the outer side of the longitudinal front line of the femur to a position corresponding to the rear side of the thigh and the outer side than the inner end of the groin groove There is. As a result, a tightening force is generated by the support line at a portion corresponding to the inside of the thigh where the skin greatly expands in accordance with the movement of the wearer.

(Embodiment 1)
It will be as follows if one Embodiment of this invention is demonstrated based on FIGS. 1-5. In the present embodiment, the leg wear according to the present invention is applied to spats as an example. However, the present invention is not limited to the spats, and can be suitably applied to tights, tubular supporters, long socks, and various other leg wears.

(On the onset of pain in knee osteoarthritis)
First, the onset of pain in knee osteoarthritis will be described based on FIGS. 3 and 13A. FIG. 3 is a figure for demonstrating the pain of the knee which arises by O leg deformation. (A) of FIG. 13 is a figure explaining the bone of a leg.
(A) of FIG. 3 is a figure which shows the leg of O leg state, (b) of FIG. 3-(d) of FIG. 3 is the elements on larger scale of the knee joint of (a) of FIG. (B) of FIG. 3 shows the condition of a normal knee joint, (c) of FIG. 3 shows the condition of the early to middle of osteoarthritis of the knee, (d) of FIG. 3 shows the condition of the knee osteoarthritis Indicates the status of the advanced stage.

  Generally, Japanese have many O-legs of varus knees as shown in FIG. 3 (a). O If knee deformity continues, osteoarthritis of the knee develops, causing arthritis, deformity and pain in the knee.

  Specifically, in the normal knee joint, as shown in FIG. 3 (b), the surfaces of the tibia 22 and the femur 20 of the joint are covered with a cartilage 40 composed of an elastic tissue, and the movement of the joint Make it smooth.

  However, when the condition of the O leg continues, the cartilage 40 of the knee joint is worn away, and the distance between the tibia 22 and the femur 20 becomes narrow. As shown in (c) of FIG. 3, when the wear of the cartilage 40 is advanced to some extent, arthritis is caused by bending and stretching of the knee and rising, an increase in load on the knee during walking, and stimulation by degeneration of the cartilage 40 and meniscus. It occurs. Arthritis causes pain and limitations in flexion and extension when the knee is flexed and extended.

  Furthermore, as osteoarthritis of the knee progresses and wear of the cartilage 40 progresses as shown in (d) of FIG. 3, the lower bone of the cartilage 40 is exposed or deformation of the bone scale 41 itself occurs. In this state, each time the knee is moved or stands and walks, the hard bones directly collide with each other, causing strong pain, and the restriction of bending and extension of the knee also becomes high.

  Next, with reference to FIG. FIG. 4 is a diagram for explaining the inverted moment, and FIGS. 4 (a) and 4 (b) show the condition of the normal leg, and FIGS. 4 (c) and 4 (d). ) Shows the state of the O-leg deformed leg.

  Inversion moment is an amount of force to invert knee joint 31 generated by the distance from the knee joint rotation center to the floor reaction force acting line. The floor reaction force acting line is indicated by a single arrow in (c) of FIG. 4 and is a line connecting the center of gravity of the foot (middle of the contact point of the foot) to the center of gravity Z of the body (around the navel). The knee joint rotation center is the knee joint 31. The distance from the knee joint rotation center to the floor reaction force acting line is a distance shown by a double arrow in (c) of FIG. In other words, the valgus moment is a moment at which the knee tries to move outward. As the inverted moment increases, O leg deformation occurs.

  As shown in FIG. 4 (a), the femur 20 is disposed between the hip joint 30 and the knee joint 31, and the tibia 22 is placed inside between the knee joint 31 and the ankle joint 32, as shown in FIG. Rib 21 is arranged. In the normal leg condition, as shown in FIG. 4 (b), the hip joint 30, the knee joint 31, and the ankle joint 32 line up in a straight line in the upright state. Therefore, since the weight is linearly weighted on the knee joint 31 and the ankle joint 32 (arrow A in (b) of FIG. 4), no rotational force is applied to the knee joint 31.

  On the other hand, in the O-leg deformation state as shown in (c) of FIG. 4, the hip joint 30 has the knee joint 31 and the ankle joint 32 in the upright state as shown in (d) of FIG. It is located inside the straight line connecting. Therefore, the weight is applied to the inside of the knee joint 31 and the ankle joint 32 (arrow A in (d) of FIG. 4), so that the knee tends to turn to the knee joint 31 in an outward direction. The arrow B) in (d) of FIG. 4 is applied.

  Such a load from the inside of the knee joint 31 is 90% or more of the cause of the osteoarthritis of the knee, and the pain in the knee joint 31 also increases if the inverted moment increases. Therefore, in order to reduce the pain in the knee caused by osteoarthritis of the knee, it is effective to suppress the inverted moment. The spats 100 can suppress the varus moment by internally rotating the lower leg.

(Schematic configuration of the spats 100)
FIG. 1 is a front view in the case where only the left foot tightening portion 10 according to the first embodiment of the present invention is taken out. FIG. 2 is a view showing the state where the spat 100 is attached. (A) of FIG. 2 is a front view, (b) of FIG. 2 is an inner side view, (c) of FIG. 2 is a rear view, and (d) of FIG. 2 is an outer side view. In FIG. 2, the tightening portions of the right foot are not shown. In the present embodiment, in the standing position, the direction in which the top of the head of the user is located is referred to as "upper", and the direction in which the sole of the user is located is referred to as "lower".

  The spats 100, as shown in FIGS. 1 and 2, include a main body portion 101, a tightening portion 102, and a tightening portion 10. In the present invention, the main body portion 101 is knitted by a knitting machine, but can also be formed by sewing a woven fabric by a loom.

  As shown in FIG. 2, the main body portion 101 covers the lower leg, the thighs and the waist. In other words, the body portion 101 covers from the waist to the lower end of the tibia of the lower leg. The lower thigh indicates the area from the knee to the ankle. A tightening portion 10 having a stronger tightening force than the main body portion 101 and a tightening portion 102 are integrally provided in the main body portion 101. The tightening force indicates a pulling force, and that the tightening force is stronger than the main body portion 101 indicates that each tightening portion has lower elasticity than the main body portion 101 (the other region). In addition, the tightening force of each tightening portion has a pulling force in the longitudinal direction. Thereby, in each tightening part, the taping effect can be produced.

  The tightening portion 10 and the tightening portion 102 can be formed by, for example, adjusting the stitch (stitch) in the main body portion 101, changing the type of yarn, changing the material, or bonding the fabric. Specifically, for example, in the present embodiment, the tightening portion 10 uses the same yarn as the main body portion 101, and reduces the elasticity by reducing the size of the stitches. As a result, the tightening portion 10 can be formed without forming a yarn switching portion which occurs when a different thread from the main body portion 101 is used for the tightening portion 10. Therefore, the terminal (step) of the switching part of the thread is eliminated, there is no influence on the skin such as the marking of the switching part on the skin, and the feeling of fabric does not feel uncomfortable even when worn for a long time.

  Further, as another method of providing each tightening portion, it is also possible to change the stitch structure by tack knitting or the like, or to reduce the stretchability by insertion of a low stretch yarn, application of a resin or the like. Specifically, for example, in the case of bonding the dough to strengthen the tightening force, each tightening portion is formed on the inner surface side (skin side) of the main body portion 101 (base material layer) constituting the spats 100 as a whole. It is possible to laminate and form a material having a higher tightening force than in the other regions. In particular, when inserting a low expansion / contraction yarn or applying a resin to the inside of the spats 100, each tightening portion can be provided without impairing the appearance.

  The main body portion 101 is provided with a mark (not shown) by which the user can visually recognize before and after the spats 100 when the spats 100 are worn. This makes it easy to wear the spats 100 in an appropriate position.

  The spats 100 are made of a stretchable material. For example, the spats 100 may use Warfill (Asahi Kasei Seisen Co., Ltd. registered trademark, composition: cupra 50%, polyester 50%) for the surface yarn material. The cupra makes it soft and feels better. In addition, the texture is softened and the touch is improved by smoothing the surface using a filament that has a large amount of air and a bulge. In addition, since the surface of the filament is smooth, static electricity hardly occurs. The spats 100 may be made of a partially breathable material depending on the application.

  It is desirable that the main body portion 101 and the respective tightening portions have the same color and the same material. This makes it possible to reduce knee pain while keeping the appearance close to everyday wear spats.

  The thickness of the main body portion 101 can be about 0.02 mm to 0.03 mm. With the configuration of the tightening portion 10 described later, even with a thin cloth, it is possible to suppress the inward moment without excessive pressure and tightening, so it is possible to provide the spats 100 without deteriorating the comfort. it can.

  The tightening portion 102 has a semicircular shape whose lower side is an ellipse, and is formed at a position covering the lower abdomen in a state where the spats 100 are attached, and suppresses the lower abdomen.

(Tensioner 10)
As shown in FIG. 1 and FIG. 2, the tightening portion 10 includes a first lower leg tightening portion 1, a second lower leg tightening portion 2, a knee joint tightening portion 3, a seam muscle tightening portion 4, a thin muscle tightening portion 5, a hamstrings A tightening portion 6 and a medial broad muscle tightening portion 7 are provided.

(First lower leg tightening part 1)
The first lower leg tightening portion 1 is in the form of a band, from the first side of the upper end of the tibia or the upper end of the rib, through the anterior surface of the tibia and calcaneus, the posterior surface of the tibia and the rib, and the second side of the lower end of the tibia or lower rib The second side is the medial side of the tibial lower end when the first side is the medial side of the tibial upper end, and the second side is the lateral side of the tibia upper end; Is the lateral side of the lower end of the rib.

  Specifically, as shown in FIGS. 1 and 2, with the first lower leg tightening portion 1 attached with the spats 100, the anterior surface of the tibia and calcaneus, the posterior surface of the tibia and calcaneus from the medial side of the upper end of the tibia As it passes in order, it is formed to reach the medial side of the lower end of the tibia. In other words, the first lower leg tightening portion 1 is formed in a spiral shape from the lower upper end inside near the patella to the inner side of the lower lower end near the inner heel via the shin and the calf. The first lower leg tightening portion 1 internally rotates the lower leg by guiding the lower leg around the above-mentioned route, and guides the knee inward. Internal rotation of the lower leg means that the lower leg (from knee to ankle) rotates inward.

  The bone interlocks with the body, and when any bone angle is changed, other bones are interlocked together to change the alignment. For example, when the arch of the sole collapses, bones move to the ankles, knees, and hips in conjunction with it, causing pain and the like in the future.

  The spats 100 cause the lower leg to rotate internally by the first lower leg tightening portion 1. This causes bone interlocking in which the bone alignment is changed in the direction of closing the O leg. In other words, the first lower leg tightening portion 1 can prevent bone interlocking such that the knee points outward.

  It is desirable that the first lower leg tightening portion 1 be formed so as to make one turn around the lower leg. When the first lower leg tightening portion 1 is formed to go around the lower leg portion one or more turns, the angle between the first lower leg tightening portion 1 and the ground becomes smaller, and the tension in the longitudinal direction becomes weaker. In addition, if the circumference of the lower thigh portion of the first lower leg tightening portion 1 is less than or equal to one turn, the angle with the ground becomes large, and the tension in only the vertical direction is obtained. The width of the first lower leg tightening portion 1 can be, for example, about 1.5 cm to 4.0 cm. The width of the first lower leg tightening portion 1 and the second lower leg tightening portion 2 becomes thinner toward the foot according to the thickness of the foot.

  Furthermore, starting from the medial side of the upper end of the tibia at the first lower leg tightening portion 1 and ending at the medial side of the lower end of the lower end of the tibia, the starting point is at least the medial side of the upper end of the upper tibia It is desirable to be in the middle of the side, preferably behind the center of the medial side of the upper end of the tibia. Further, it is desirable that the end point is at least the center of the medial side of the lower end of the tibia, preferably in front of the center of the medial side of the lower end of the tibia on one side when the inside of the lower leg is viewed laterally. With such a design, the lower leg can be effectively internally rotated.

(2nd lower thigh tightening part 2)
The second lower leg tightening portion 2 is in a band shape, and with the spats 100 attached, from the outer lateral side of the upper end of the rib, sequentially through the anterior surface of the tibia and ribs, the posterior surface of the tibia and rib, and the lateral side of the lower end It is formed as. Further, the tightening force of the first lower leg tightening portion 1 is stronger than the tightening force of the second lower leg tightening portion 2. Internal rotation of the lower leg may promote X leg. Therefore, by arranging the second lower leg tightening portion, the lower leg is guided in the external rotation direction with a force weaker than that of the first lower leg tightening portion 1. Thereby, it can suppress that the 1st lower leg tightening part carries out internal rotation of the lower leg part too much.

  Further, by making the width of the first lower leg tightening portion 1 wider than the width of the second lower leg tightening portion 2, the tightening force of the first lower leg tightening portion 1 may be made stronger than the second lower leg tightening portion 2. . Specifically, the tightening force per unit area of the first lower leg tightening portion 1 and the tightening force per unit area of the second lower leg tightening portion 2 are made the same, and the width of the first lower leg tightening portion 1 is the second lower leg By making the width of the tightening portion 2 wider, the tightening force of the entire first lower leg tightening portion 1 can be made stronger than the entire tightening force of the second lower leg tightening portion 2. Further, in addition to the method of widening the width, the tightening force per unit area may be strengthened by the type of yarn, the bonding of the fabric, or the like. Alternatively, the tightening force per unit area may be increased after the width is increased. It is desirable that the difference in tightening force between the first lower leg tightening portion 1 and the second lower leg tightening portion 2 be appropriately set in accordance with the degree of the O leg of the individual or the like.

  The first lower leg tightening portion 1 and the second lower leg tightening portion 2 intersect at the center in the width direction of the lower leg in the front of the tibia and rib, and in the rear in the width direction of the lower leg It is desirable to cross at Thereby, the balance of the twist is maintained, and the lower leg can be internally rotated in a balanced manner. The width of the second lower leg tightening portion 2 can be, for example, about 1.5 cm to 3.0 cm.

(Knee joint tightening part 3)
The knee joint tightening portion 3 is formed so as to surround the patella 23 (see (a) of FIG. 13) in a state where the spats 100 are attached. In other words, the knee joint tightening portion 3 is formed so as to surround the patella. A first lower leg tightening portion 1 and a second lower leg tightening portion 2 are connected to the lower portion of the knee joint tightening portion 3. In addition, a thin muscle tightening portion 5, a hamstrings tightening portion 6, and a medial broad muscle tightening portion 7 are connected to the upper portion of the knee joint tightening portion 3.

  Since the knee joint tightening portion 3 is provided around the knee joint, it is possible to damp the movement of the knee joint (restrain the movement). In addition, since the first lower leg tightening portion 1 is connected to the knee joint tightening portion 3, the first lower leg tightening portion 1 pulls the knee joint tightening portion 3, thereby enhancing the internal reaction moment suppressing effect by the internal rotation of the knee joint. be able to. The width of the knee joint tightening portion 3 can be, for example, about 4.0 cm at the upper part and about 3.0 cm at the lower part.

(Seal work muscle tightening part 4, thin muscle tightening part 5, and hamstrings tightening part 6)
In order to effectively reduce the motion of the knee joint, in addition to the method of directly damping the movement and rotation of the knee itself, it is effective to damp the extra motion of the muscle connected to the knee joint. (B) of FIG. 13 is a figure explaining the muscle of a leg. In the present embodiment, attention is paid to Hamstrings 53 including medial muscle 51, thin muscle 52, biceps femoris muscle, etc., and medial lateralis muscle 54 shown in FIG. The spats 100 have a tightness to support stable movement of these muscles.

  The sewing muscle tightening portion 4 is formed to have a tightening force along the line direction of the sewing muscle 51 in a state where the spats 100 are attached. Specifically, the sewing muscle tightening portion 4 is spirally disposed around the thigh along the direction of the muscle of the sewing muscle 51. In other words, the sewing muscle tightening portion 4 is disposed so as to pass from the medial side of the femur to the anterior side of the femur, the posterior face of the femur, and to the medial side of the femur. The width of the sewing muscle tightening portion 4 can be, for example, about 3.5 to 5.0 cm. The width of the sewing muscle tightening portion 4 increases from the bottom to the top. As a result, since the sewing muscle tightening portion 4 is stabilized, it is possible to prevent the positional deviation of the sewing tightening portion 4 and the tightening portions connected to the sewing muscle tightening portion 4.

  The thin muscle tightening portion 5 is formed to have a tightening force along the muscle direction of the thin muscle 52 in a state where the spats 100 are mounted, the lower end portion is connected to the upper portion of the knee joint tightening portion 3, and the upper end portion Is connected to the sewing machine muscle tightening portion 4. In other words, the thin muscle tightening portion 5 is disposed on the posterior surface of the femur so as to extend from the medial side of the upper end of the tibia to the sewing muscle tightening portion 4. The lower end of the thin muscle tightness portion 5 is connected to the upper portion of the knee joint tightness portion 3 by a heel foot portion 55 which is a muscle group that dampens the rotation of the knee joint inside the knee joint. This can support the muscle group that damps the rotation of the knee joint, so that it is possible to damp knee joint and muscle sway. The width of the thin muscle tightening portion 5 can be, for example, about 2.5 cm.

  The hamstrings tightening portion 6 is formed to have a tightening force along the line direction of the hamstrings 53 with the spats 100 attached. Hamstrings are muscles that mainly affect knee joint flexion, as well as knee joint flexion. In other words, the hamstrings tightening portion 6 is disposed on the outer side surface of the femur so as to extend from the outer side surface of the upper end of the tibia to the back surface of the sew muscle tightening portion 4 in an arc toward the rear surface of the femur. The lower end portion of the hamstrings tightening portion 6 is connected to the upper portion of the knee joint tightening portion 3, and the upper end portion is connected to the sewing muscle tightening portion 4. The width of the hamstrings clamp portion 6 can be, for example, about 4.0 cm.

  By forming the seam muscle tightening portion 4, the thin muscle tightening portion 5 and the hamstrings tightening portion 6, the muscles supporting the knee joint can be supported, so that the knee joint and muscle movement can be damped.

  At least one of the thin muscle tightening portion 5 and the hamstrings tightening portion 6 may be provided, and the sewing muscle tightening portion 4 may be either the thin muscle tightening portion 5 or the hamstrings tightening portion 6. Or may be connected to both.

(Interior musculature tightening part 7)
The medial latissimus muscle tightening portion 7 is formed to have a clamping force in a direction intersecting the traveling direction of the muscle fibers of the medial broad muscle 54 in a state where the spats 100 are attached. A muscle fiber is a cell that constitutes a muscle, and the muscle fibers are arranged in a specific direction, and the direction in which the muscle fibers are arranged is called a running direction. Also, the muscle stretches in the running direction of the muscle fiber. When the longitudinal direction of the medial musculoskeletal region 7 crosses the traveling direction of the muscle fibers of the medial lateral muscle, the tightening force acts in the direction intersecting the traveling direction of the myofibers of the medial lateral muscle. When the muscle is tightened in the direction crossing the running direction of the muscle fibers, the muscle is stimulated and muscle output is enhanced. It is desirable that the medial visceral tightness portion 7 is formed so as to have a tightening force orthogonal to the running direction of the muscle fibers of the medial broad muscle 54 with the spats 100 attached, but the crossing angle is 90 degrees Not exclusively. In the front of the thighs, three inward parallel internal muscle tightening portions 7 are formed so as to be located between the thin muscle tightening portion 5 and the hamstrings tightening portion 6, and the inner side located at the bottom The broad muscle tightening portion 7 is connected to the upper portion of the knee joint tightening portion 3. The medial striated muscle 54 is a muscle that stretches the knee. Since the medial musculoskeletal region can be appropriately stimulated by the medial musculoskeletal region, the muscle output can be enhanced and the force to support the knee joint can be increased.

  In addition, since a thick blood vessel passes through the back of the knee, it is desirable not to provide each tightening portion on the back of the knee in order not to inhibit the blood flow by tightening. By not providing the tightening portion on the back of the knee, it is possible to prevent the inhibition of bending and stretching of the joint.

(Effect of spats 100)
FIG. 5 is a figure for demonstrating the effect by mounting | wearing the spats 100. As shown in FIG. (A) of FIG. 5 shows the force concerning a leg by mounting | wearing the spats 100, and (b) of FIG. 5 and (c) of FIG. 5 show the effect by mounting | wearing the spats 100. FIG.

  The spats 100 according to the first embodiment includes (1) tightening portions supporting muscles supporting knee joints (sewing muscle tightening portion 4, thin muscle tightening portion 5, and hamstrings tightening portion 6), and (2) knee extension. Tighten the part that stimulates the muscles (the medial broad muscle tightening part 7), (3) the tightening part that wraps around the knee joint (the knee joint tightening part 3), and It has a tightening portion (a first lower leg tightening portion 1, a second lower leg tightening portion 2) which makes it difficult for the knee to spread outward and which suppresses the inverted moment.

  The spats 100 pull the lower leg with the first lower leg tightening portion 1 wider than the second lower leg tightening portion 2 from the inside of the knee to the outer leg, as shown by arrows D and E in FIG. In the direction of arrow C, the inflexion moment of the knee joint can be suppressed and the motion of the knee can be damped in the direction of the arrow C. Thereby, O leg can be suppressed as shown to (b) of FIG.

  In addition, by supporting the muscles by each tightening portion along the muscles supporting the knee joints, as shown in (c) of FIG. 5, it is possible to make it difficult for the knees to spread outward, which causes pain and pain in the knees. Can be reduced.

  With the above structure, the spats 100 do not cause excessive pressure or tightening, as there is no corrective pressure on the knee joint or unnecessary tightening on the lower leg that causes pain or discomfort. Upset can be suppressed. That is, the spats 100 can brake the knee from turning externally without excessive loading and tightening.

  Furthermore, the main body portion 101 and each tightening portion are formed of the same material and the same color. Therefore, for example, when the spats 100 are formed in black, they have substantially the same appearance as the spats or leggings and the like worn normally, and the appearance does not notice that they have special functions. Therefore, the user can suppress knee sway and reduce knee pain just by wearing the spats 100 in the same manner as the spats worn on a daily basis without taking special measures and measures. In other words, the user can relax pain in the usual clothes, especially when climbing stairs that feels particularly heavy, and can enjoy traveling and going out without feeling pain in the knee and its anxiety.

  Further, since the spats 100 can suppress the lateral movement of the knee joint, the spats 100 can also be used as a means for supporting the knee in a sport scene or the like.

  One embodiment of the present invention will be described below with reference to FIGS. In the present example, the motion of the knee joint was measured using a Bicon (3D measurement), and the presence or absence of the reduction effect of O leg deformation of the present invention was verified.

  In this example, bare feet, a tubular product α covering a knee joint, and normal spats were used as comparisons for the spats 100. In the product α, a U-shaped taping knit for supporting the plate of the knee to be lifted is applied to a tubular main body that covers only the knee. Normal spats are spats that do not have the first lower leg tightening portion 1 and other tightening portions.

〔Test method〕
(1) A marker was attached to eight elderly women who are subjects in a state in which each comparative example is attached (a state in which nothing is attached to bare feet). FIG. 6 is a diagram for explaining measurement points of the test of the embodiment. (A) of FIG. 6 is a rear view showing a measurement place, (b) of FIG. 6 is a right side view showing a measurement place, and (c) of FIG. 6 is a front view showing a measurement place. The marker position is the pelvic region (upper anterior iliac crest, upper retroiliac crest) using the plug-in-gait lower body Ai method as shown in (a) to (c) of FIG. Leg (outside the knee joint, a straight line between the greater trochanter and the upper anterior iliac crest, and a point one-third above the greater trochanter and a straight line between the outer side of the knee joint and a straight line between the outer side of the knee joint and the outer limb) There were a total of 16 sites on the foot (outer foot, calcaneus, 2nd metatarsal head). From the above marker positions, the pelvis, right thigh, left thigh, right lower thigh, left lower thigh, right foot and left foot are made into a solid of one or more planes, and the Euler angles between faces are calculated The counter moment was identified. The motion analysis was all measured at a sampling frequency of 120 Hz.
(2) 10 m walks were carried out under each condition for 6 trials.

〔Test results〕
The test results will be described based on FIGS. (A) of FIG. 7 is a graph which shows the test result of the internal and external rotation angle of an Example, FIG. 7: (b) is a table | surface which shows the test result of the internal and external rotation angle of an Example. (A) of FIG. 8 is a graph which shows the test result of the inverted moment of an Example, (b) of FIG. 8 is a table | surface which shows the test result of the inverted moment of an Example. FIG. 9 is a diagram for explaining an in-and-out rotation angle.

  The vertical axis in (a) of FIG. 7 indicates the inward / outward rotation angle. The vertical axis in (a) of FIG. 8 indicates the magnitude of the moment. SD (Standard Deviation) in FIG. 7A and FIG. 8A is a standard deviation, and SE (Standard Error) is a standard error.

  The inside and outside turning angle is a turning angle at which the knee swings inward or outward, and when the value is low, the knee is more upright. Specifically, for example, the in-and-out rotation angle is the angle θ shown in FIG. 9, and it is perpendicular to the ground through the weir, and the line of intersection between the surface extending in the front direction of the body and the ground, and the outer end of the weir And the end of the foot on the outside (little finger side). As shown in FIG. 9, when the straight line is positioned inside the body than the intersection line, the angle θ indicates an internal rotation angle, and when the straight line is positioned outside the body than the intersection line, the angle θ is Indicates the external rotation angle. The internal and external rotation angles shown in FIG. 7 are both positive for the internal and external rotation angles. A larger internal rotation angle promotes the X leg, and a larger external rotation angle promotes the O leg.

  As shown in FIG. 7, when the spats 100 were attached, the inward / outward rotation angle became smaller as compared with the other comparative examples. This indicates that the wearing of the spats 100 suppressed the rotation of the lower leg regardless of the internal and external rotation of the lower leg. In other words, it indicates that the spats 100 have dampened knee sway. Considering that the O leg is the majority in Japanese, it is considered that the function of braking the lower thigh of the spats 100 in the direction of the internal rotation suppresses the internal and external rotational angles. Moreover, when the average value was compared with the case where it mounted | worn with the spats 100 and the case where it was barefoot especially, the internal and external rotation angle became small about 30%. This indicates that wearing the spats 100 reduced the rotation of the lower leg by about 30%.

  As shown in FIG. 8, when the spats 100 were attached, the ballback moment decreased as compared with the other comparative examples. This indicates that wearing of the spats 100 suppressed the knee from turning outward. Moreover, when the average value was compared with the case where it mounted | worn with the spats 100 especially and the case where it was barefoot, the inverted moment became about 35% small. This indicates that the attachment of the spats 100 reduced the force by which the knee spreads outward by about 35%.

  From the above results, it was found that there is a correlation between the inverted moment and the inward / outward turning angle, and the inverted moment can be suppressed by braking the involute.

  Thus, in the present example, the effect of the spats 100 for suppressing the inverted moment was recognized. That is, by internally rotating the lower leg with the spats 100, the inverted moment can be suppressed, so that it is possible to damp the external rotation of the knee, that is, to damp the movement of the knee joint.

[Supplement]
For reference, the appearance of the spats 100 according to the present invention is shown in (a) to (e) of FIG. 10 and (e) to (e) of FIG. (A)-(e) of FIG. 10 are drawings which show the external appearance of the spats based on this invention. 10 (a) is a plan view of the spats 100, FIG. 10 (b) is a front view of the spats 100, and FIG. 10 (c) is an outside (left side) of the spats 100. FIG. 10 (d) is a back view of the spats 100, and FIG. 10 (e) is a bottom view of the spats 100. FIG. (A) to (e) of FIG. 11 are drawing substitute photographs showing the appearance of the spats 100 according to the present invention. In particular, (a) of FIG. 11 is a drawing-substituting photograph showing the flat surface of the spats, (b) of FIG. 11 is a drawing-substituting photo showing the front of the spats, and (c) of FIG. 11D is a drawing substitute photo showing the back of the spats, FIG. 11D is a drawing substitute photo showing the outside (left side) side of the spats, and FIG. 11E is a bottom view of the spats It is a drawing substitute photograph. Portions indicated by dots in (a) of FIG. 11 and (e) of FIG. 11 show fillings for adjusting the shape of the article. Note that, since the left side surface and the right side surface of the spats 100 are symmetrical, the drawing substitute photograph showing the right side surface is omitted. Further, in FIG. 11, the illustration of the tightening portion 102 is omitted.

  Although the drawing substitute photograph of FIG. 11 illustrates the main body portion 101 as black and each tightening portion as gray for easy understanding, the present invention is not limited thereto. The main body portion 101 and the tightening portions may have the same color or different colors. For example, when each tightening portion is formed by stitch adjustment and the main body portion 101 and each tightening portion have the same color, there is almost no difference in color between the main body portion 101 and each tightening portion. Specifically, the main body portion 101 may be dark black and each tightening portion may be light black, or each tightening portion may be dark black and the main body portion 101 may be light black.

  In addition, six women in their 50s or more who usually have pain in their knees were allowed to wear the spats 100 having the configuration shown in FIG. As a result of the questionnaire, 4 out of 6 people answered that they could feel relief of knee pain. Specifically, (1) there was no knee pain at all. (2) The material and the knee felt well and I could move without worrying about the pain in my knee when I was wearing it. (3) It feels like the whole foot has fallen and it feels good. I could go up and down the stairs smoothly. (4) The knee was supported and I could walk without worrying about pain. I felt pain, because I felt pain if I did not wear it, I could get an answer such as.

Second Embodiment
As the valgus moment in which the knee tries to move inward increases, X-leg deformation occurs. In the X-leg deformed state, the hip joint 30 is located outside the straight line connecting the knee joint 31 and the ankle joint 32 (see (a) in FIG. 4, not shown). Therefore, since the weight is weighted on the outside of the knee joint 31 and the ankle joint 32, a rotational force that causes the knee to move inward is applied to the knee joint 31, that is, a valgus moment. Therefore, in order to reduce the X-leg deformation, it is effective to suppress the valgus moment by externally rotating the lower leg.

  In the present embodiment, the spats 100a capable of suppressing the ball reversion moment by externally rotating the lower leg will be described. The spats 100a is different from the spats 100 shown in FIGS. 1 and 2 in that a fastening part 10a is provided instead of the fastening part 10, and the other configuration is the same. In other words, in the spats 100 shown in FIG. 2, the spats 100 a are provided with the fastening parts 10 a instead of the fastening parts 10.

(Tensioner 10a)
FIG. 12 is a front view in the case where only the left foot tightening portion 10a of the spats according to the second embodiment is taken out.

  The tightening portion 10a is provided with a first lower leg tightening portion 1a and a second lower leg tightening portion 2a in place of the first lower leg tightening portion 1 and the second lower leg tightening portion 2 as compared with the tightening portion 10 shown in FIG. The other configurations are similar.

(First lower leg tightening part 1a)
The first lower leg tightening portion 1a is in the form of a band, and is formed to pass from the outer lateral surface of the upper end of the rib, the anterior surface of the tibia and the rib, the posterior surface of the tibia and the rib, and the lateral side of the lower end of the rib. As a result, the lower leg is pulled by the first lower leg tightening portion from the outside to the inside of the knee so that the lower leg rotates externally. Therefore, it is possible to suppress the valgus moment of the knee joint and to damp the sway of the knee. As a result, it is possible to brake the knee from turning externally without excessive application pressure and tightening.

(2nd lower leg tightening part 2a)
The second lower leg tightening portion 2a is in the form of a band, and is formed to pass from the inner side of the upper end of the tibia to the anterior side of the tibia and the calcaneus, the posterior side of the tibia and the calcaneus, and the medial side of the lower end of the tibia. In addition, the tightening force of the first lower leg tightening portion 1a is stronger than the tightening force of the second lower leg tightening portion 2a. Therefore, the second lower leg tightening portion 2a guides the lower leg portion in the internal rotation direction with a weaker force than the first lower leg tightening portion 1a, so that the first lower leg tightening portion 1a excessively rotates the lower leg portion. It can be suppressed.
