Description

[Technical Field]

[0001] The present invention relates to a brace for releasing adhesion of fascia and muscles, and more particularly to a technique for a brace that causes a protrusion to abut against the adhered portion at the medial and lateral midline of the gastrocnemius from the posterior proximal part to the central part of the lower leg, and separates the adhesion through movement. [Background Art]

[0002] It is considered that one of the causes of pathological conditions such as ingrown toenail, hallux valgus, flatfoot and other deformations of toes and foot is that excessive force is applied when the bone of the lower leg moves over the foot during the gait cycle. This excessive force leads to hardening of the muscles of the foot and toes, and also leads to destruction of the skeleton of the foot and toes. The triceps surae consists of the soleus and the medial and lateral heads of the gastrocnemius. In pathological conditions such as ingrown toenail, hallux valgus and flatfoot, the gastrocnemius is also pulled downward together with the shortened and contracted soleus during initial contact of walking. Then the gastrocnemius gets caught at the distal medial and lateral bifurcation points. Therefore, at the median portion which is the bifurcation between the medial and lateral sides of the gastrocnemius, the medial and lateral muscles and fascia adhere to each other in a manner that the medial and lateral heads of the gastrocnemius are rolled inward.

[0003] Various techniques have been conventionally proposed for myofascial release. For example, a myofascial release treatment tool (see Patent Document 1) has been proposed and is a known technique. However, according to this treatment tool, although adhesion between subcutaneous tissue and fascia can be separated, it cannot separate adhesion of muscles between the medial head and lateral head of the gastrocnemius and adhesion of fascia between the muscles, so the above problem has not been solved.

[0004] Based on the idea that if adhesion of the medial and lateral muscles and fascia of the gastrocnemius can be removed, it would be useful for the pathological condition of foot and toe deformation, the applicant of the present application has arrived at the proposal of a brace capable of effectively separating adhesion of the medial and lateral muscles of the gastrocnemius.

[0005] [Patent Document 1] Japanese Patent Publication No. 2020-92808 [Overview of the project] [Problems that the invention aims to solve]

[0006] In view of the above problems, the present invention aims to provide a device that can efficiently separate adhesions between the medial and lateral heads of the gastrocnemius muscle, as well as adhesions of the fascia between muscles. [Means for solving the problem]

[0007] To solve the above-mentioned problems, the fascia and muscle adhesion release orthosis according to the present invention comprises a band that can be wrapped around the calf, and a projection on the inner surface of the band that presses in a direction to separate the adhesion between the medial and lateral heads of the gastrocnemius muscle, the projection biases both the medial and lateral heads in a direction that separates their fascia, and the projection is detachably attached to any position on the inside of the band.

[0008] Furthermore, the present invention employs a method in which the shape of the projection is a frustoconical shape or a frustoconical shape with a rounded edge on the upper surface, the upper surface is a pressure limiting part that limits the amount of pressure applied to the calf, and the side surface of the frustoconical shape is a gastrocnemius muscle biasing part that biases the medial and lateral heads of the gastrocnemius muscle from an oblique angle.

[0009] Furthermore, the present invention provides a projection whose shape is spherical or spherical with a rounded edge on the upper surface, the spherical base is generated from a sphere with radius R1 and does not include the center point of the sphere, the upper surface is a pressure limiting portion that limits the amount of pressure applied to the calf, the spherical surface of the spherical base is a gastrocnemius muscle biasing portion that biases the medial and lateral heads of the gastrocnemius muscle from an oblique angle, and the upper surface is a flat surface or a spherical notch generated from a sphere with radius R2, with R2 being greater than R1.

[0010] Furthermore, the present invention employs a method in which the angle formed by the line connecting the center point of the bottom surface of the projection and the edge point, and the line connecting the edge point and the nearest point on the top surface, is between 30 and 70 degrees.

[0011] Furthermore, unlike acupressure devices, the present invention employs a method in which the diameter of the top surface is 5 mm or more, and the diameter of the bottom surface is greater than the width of the band.

[0012] Furthermore, the present invention employs a method in which the projection has a cylindrical portion on its bottom side. [Effects of the Invention]

[0013] The fascia and muscle adhesion release orthosis according to the present invention can effectively release adhesions in the medial and lateral heads of the gastrocnemius muscle, thereby bringing the gastrocnemius muscle closer to a normal state and improving the pathological condition of foot and toe deformities.

[0015] The most notable feature of the fascia and muscle adhesion release orthosis according to the present invention is its ability to effectively release adhesions in the medial and lateral heads of the gastrocnemius muscle.

[0016] The present invention will be described with reference to FIGS. 1 to 5.

[0017] The fascial and muscular adhesion release device 1 is a device for peeling adhesion between the medial head and lateral head of the gastrocnemius muscle. In other words, by wrapping the device around the calf, the protrusion 20 is continuously pressed between the medial head and lateral head of the gastrocnemius muscle to eliminate adhesion therebetween. There have been devices such as acupressure pressing devices that press a protrusion against the skin, but there has been no device that peels adhesions of muscles. Although manual methods are available for peeling muscle adhesions, continuous stimulation of the adhered area is required, so a device that can be continuously fixed has been suitable. In addition, general myofascial release aims to resolve adhesions between subcutaneous tissue and fascia, and there has been no device that resolves adhesions between two muscles and the fasciae covering the muscles as in the present invention. A fascia and muscle adhesion release device 1 includes a band 10 that can be wrapped around a calf and a protrusion 20.

[0018] The band 10 is for fixing the fascia and muscle adhesion release device 1 around the calf of a lower leg L. The band 10 is elongated, has a folded ring portion 12 at one end, and a distal end portion 13 at the other end, and a hook-and-loop fastener 14 for band adjustment is provided on the distal end portion 13 and a corresponding portion of the distal end portion 13. By passing the distal end portion 13 through the folded ring portion 12 and fixing with the band adjustment hook-and-loop fastener 14, the band 10 can be adjusted to a size that fits the calf on which it is worn. The band 10 is made of a non-elastic material such as a fabric material. This is because if the band has elasticity, the expansion and contraction causes the compression exerted by the protrusion 20 to be overcome by muscle contraction, resulting in weakened compression force. A hook-and-loop fastener 11 is disposed in a predetermined region on the inner side of the band 10. This hook-and-loop fastener 11 corresponds to a hook-and-loop fastener 60 on the protrusion 20 side, and integrates the band 10 and the protrusion 20. The hook-and-loop fastener 11 covers a relatively wide area, allowing the fixing position of the protrusion 20 to be changed. By changing the fixing position of the protrusion 20, the position of the folded ring portion 12 and the like when the fascia and muscle adhesion release device 1 is wrapped around the lower leg L can be adjusted.

[0019] The protrusion 20 is a portion that presses in a direction to peel adhesions between the medial head and lateral head of the gastrocnemius muscle. When the fascia and muscle adhesion release device 1 is attached to the lower leg L, the protrusion 20 urges the gastrocnemius muscle GA. The protrusion 20 is semi-rigid, and for example, EVA resin is conceivable as a material thereof. The projection 20 consists of a pressure limiting portion 21, a calf muscle biasing portion 22, and a cylinder 50. The indentation limiting portion 21 is the upper central part of the projection 20, and is generally flat with rounded edges. The diameter of the indentation limiting portion 21 is preferably 5 mm or more, and about 10 mm. When the projection 20 is pressed against the lower leg L, it makes direct contact with the lower leg L. If the indentation limiting portion 21 is small, the projection 20 will sink more into the lower leg L, increasing the adhesion-breaking effect, but the projection will become more acute, which may increase the pain caused by compression. Conversely, if the indentation limiting portion 21 is large, the amount the projection 20 sinks into the lower leg L will be reduced, and the adhesion-releasing effect will be lower, but the projection will be more obtuse, which may reduce the pain caused by compression. The size of the indentation limiting section 21 can be changed according to the patient's age, symptoms, etc., to optimize the amount of adhesion release. The rounded edges help to reduce pain and discomfort caused by sharp corners.

[0020] The gastrocnemius muscle biasing portion 22 is located on the side of the projection 20 and is generally oblique in shape. The purpose of pressing the projection 20 against the lower leg L is to separate the adhesions between the medial head MG and the lateral head LG of the gastrocnemius muscle GA. The gastrocnemius muscle biasing part 22 biases both the medial head MG and the lateral head LG at an angle, thereby biasing them in a direction that separates them and reducing adhesions between the medial head MG and the lateral head LG. Focusing on the fascia of each muscle, the biasing applies to both the medial head and the lateral head in a direction that separates their respective fascia. One example of the shape of the gastrocnemius muscle biasing portion 22 is a shape that combines a truncated cone 30 and a cylinder 50. A truncated cone with a rounded edge on its top surface is preferable because it avoids unnecessary irritation from sharp corners. The upper part is a compression limiting section that restricts the amount of pressure applied to the calf, and the frustoconical side is a gastrocnemius biasing section that applies oblique bias to the medial and lateral heads of the gastrocnemius muscle. In the frustum of the cone 30, which is the gastrocnemius muscle biasing portion 22, the angle formed by the straight line from the center point of the base portion 33 to the base portion 33 and the straight line from any point on its edge to the nearest point on the edge of the upper portion 31 is preferably between 30 and 70 degrees (Figure 5(h)). If the angle is too large, the lateral biasing force on the muscle will be too strong, and if the angle is too small, the lateral biasing force will be too weak. An angle of 60 degrees is even more preferable, as it allows for an appropriate biasing force to be applied to the muscle. The cylinder 50 is for positioning the truncated cone 30, which consists of a pressure limiting section 21 and a calf muscle biasing section 22, at a certain height from the band 10. The truncated cone 30 and the cylinder 50 may be made as a single unit, or they may be made separately and then combined into one unit. A hook-and-loop fastener 60 is positioned at the bottom of the cylinder 50, and it can be attached to and detached at any position inside the band 10 by the hook-and-loop fastener 11 of the band 10. By making the diameter of the base portion 33 larger than the width of the band 10, as shown in Figure 3(b), when the fascia and muscle adhesion release orthosis 1 is attached to the lower leg L, the position of the projection portion 20 can always be determined, making it convenient to easily detect and correct any misalignment.

[0021] Ingrown toenails, where the big toenail curves inward, can progress to the side of the nail digging into the toe, causing pain due to pressure and severe pain due to inflammation. Foot conditions such as ingrown toenails, bunions, and flat feet are caused by stiffening of the muscles that move the toes and feet, preventing proper movement. The calf muscles and other related factors that cause this problem will be explained in accordance with Figure 2(a). The lower leg (L) consists of the soleus muscle (Sol) and the medial head (MG) and lateral head (LG) of the gastrocnemius muscle (GA), collectively known as the triceps surae muscle. The soleus muscle (Sol) and the medial head (MG) and lateral head (LG) of the gastrocnemius muscle (GA) are connected to the Achilles tendon (AT). The soleus muscle (Sol) and the gastrocnemius muscle (GA) are used at different times during walking.

[0022] Walking technique will be explained using Figure 2(b) as a guide. Walking is divided into initial contact, load response phase, mid-stance phase, terminal stance phase, and pre-swing phase. Initial contact refers to the moment when the foot first touches the ground during walking. It marks the beginning of the gait cycle and plays a role in preparing for shock absorption. The loading response phase is the period from the moment one foot touches the ground until the opposite foot leaves the ground. Mid-stance is the period within the "stance phase" when the foot is in contact with the ground, until the forefoot of the opposite foot that has left the ground crosses over the stance leg. Terminal stance refers to the period until the opposite lower limb lands. Pre-swing is the period until the foot leaves the ground (off-ground). In the correct walking technique, the toes are raised when the heel touches the ground during the initial contact (part A). During the terminal stance phase, the soleus muscle (Sol) works to maintain balance with the arch of the foot, while the gastrocnemius muscle (GA) performs a movement that curls the lower leg backward. Therefore, the gastrocnemius muscle (GA) can be said to be a muscle that should be used more in running than walking. The muscles attached to the sole of the foot, the arch of the toes, and the Achilles tendon are stretched, allowing for balance and a forward shift in the center of gravity (part B). However, in poor walking posture where the toes drop during initial contact with the ground, the gastrocnemius muscle (GA), like the soleus muscle (Sol), works excessively in a downward direction instead of its intended upward direction when the lower leg moves over the foot. Since the gastrocnemius muscle (GA) is a muscle that pulls upward with a winding action, in a normal state it is better to have volume in the upper part of the calf. However, with poor walking posture, the gastrocnemius muscle is pulled downward in a winding motion between the medial head (MG) and lateral head (LG), resulting in volume being added to the lower lateral part of the gastrocnemius. As a result, the muscles that make up the toes and foot skeleton are subjected to excessive strain, causing them to stiffen or shorten, leading to deformation of the foot and toe skeleton. This is a contributing factor to foot conditions such as ingrown toenails, bunions, and flat feet.

[0023] The fitting of the fascia and muscle adhesion release orthosis 1 will be explained in accordance with Figure 3. The orthosis should be fitted so that the projection 20 is located on the upper posterior part of the calf, as shown in Figure 3(a) or (b). The external appearance will be as shown in (b). In relation to the medial head MG and lateral head LG of the gastrocnemius muscle GA, the projection 20 should be positioned between the medial head MG and the lateral head LG. For example, press on the upper back of the calf, near the midline, to identify the painful spot (Figure 3(c)). Place the projection 20 against the painful spot, pass the tip 13 through the folded ring portion 12 of the band 10, tighten it, and secure it with the band adjustment hook-and-loop fastener 14 (Figure 3(d)). The fascia and muscle adhesion release orthosis 1 is mainly held in place by a band 10 that contacts the tibial surface KM, which is the anterior side of the tibia, and by projections 20 that contact the medial and lateral heads of the gastrocnemius muscle. Therefore, even when tightened, it does not restrict blood flow. It is effective simply by wearing it while going about your normal daily life. The projection 20 compresses the medial and lateral heads of the gastrocnemius muscle. This is because, while compressed, movement of the muscle through walking or other means causes the adhesions to separate. The area to be compressed varies from patient to patient. The protrusion 20 is placed on a hardened or tender area near the midline, and the band 10 is secured with the band adjustment hook-and-loop fastener 14 to prevent the protrusion 20 from shifting. In that state, perform general daily activities such as walking. These activities will move the muscles, making it easier to release adhesions.

[0024] Figure 4 illustrates the process of resolving adhesions between the medial head MG and lateral head LG of the gastrocnemius muscle. Figure 4(a) shows the condition before applying the fascia and muscle adhesion release orthosis 1. The lateral surface of the medial head MG and the lateral surface of the lateral head LG are adhered at the adhesion site AD. This can be described as either the adhesion between the medial head MG and the lateral head LG muscles, or the adhesion between the fascia covering the medial head MG and the lateral head LG muscles. Figure 4(b) shows the fascia and muscle adhesion release orthosis 1 in place. The projection 20 is positioned between the medial head MG and the lateral head LG. The gastrocnemius muscle biasing portion 22, which is the side of the projection 20, biases the medial head MG and lateral head LG diagonally downward, and as a whole, moves in a direction that separates the adhesions and reduces the adhesion area AD. The indentation amount limiting portion 21 controls the amount of biasing. Without the indentation amount limiting portion 21, the projection 20 would penetrate far between the medial head MG and lateral head LG, resulting in a large amount of biasing, which could cause significant pain to the patient. With the indentation amount limiting portion 21, the patient can reduce adhesions with an appropriate amount of biasing. Figure 4(c) shows an example of someone wearing the device while performing some daily activities. The adhesion has been resolved, and the adhesion site A and D have disappeared. In this way, the effect can be obtained by continuously stimulating the adhesion area while wearing the fascia and muscle adhesion release device 1.

[0025] As an example of the shape of the projection 20, a shape combining a truncated cone 30 and a cylinder 50 was described. However, as a structure for separating adhesions between the medial head MG and lateral head LG of the gastrocnemius muscle GA, it is possible that the shape may deform depending on the patient's age and the degree of adhesion. Figure 5(a) shows the shape of the projection 20 described above. It is a shape formed by combining the frustum of a cone 30 and the cylinder 50. The edge of the upper surface 31 of the frustum of a cone 30 is rounded. The lower part of the cylinder 50 is fixed to the hook-and-loop fastener 11 of the band 10 by the hook-and-loop fastener 60. Figure 5(b) shows that the edge of the upper surface 31 of the frustum of the cone 30 is not rounded. By adopting this shape, the area of ​​the gastrocnemius muscle biasing portion 22 can be increased, thereby improving the efficiency of the release. Figure 5(c) shows the combined shape of the sphere base 40 and the cylinder 50. The upper surface 42 is shaped like a sphere notch 41. Geometrically, a sphere vault is a solid formed when a sphere is cut by two parallel planes, and the side portion of the sphere vault (the original spherical portion) is called a sphere band. Furthermore, a three-dimensional object created when a sphere is cut by a single plane is called a spherical cutout. The side portion of a ball that has a defect (the original spherical part) is called the ball cap. By changing the shape of the projection 20 from a truncated cone 30 to a spherical base 40, the gastrocnemius muscle biasing portion 22 of the projection 20 becomes more rounded. By changing the shape of the indentation amount limiting portion 21 from a flat surface to a spherical notch 41, the indentation amount limiting portion 21 becomes rounded. By adopting this shape, pain and discomfort during pressure welding can be reduced. The shape of the sphere base 40 is generally similar to that of the frustum of the cone 30, and the sphere base 40, for example, if generated from a sphere of radius R1, does not include the center point of that sphere. With this shape, the sphere band 45 is generally tapered upwards, similar to the side surface 34 of the frustum of the cone 30. The shape of the upper surface portion 42 is that of a ball-shaped cutout 41, so the central part is slightly bulging. The upper surface portion 42 is the indentation amount limiting portion 21, so it is nearly flat, for example, a ball-shaped cap 46 generated from a diameter R2, where R2 is larger than R1 of the ball base 40. By adopting this shape, the upper surface can always be made flatter than the sides (Figure 5(g)).

[0026] If the patient is a child, or if it is desired to reduce the amount of pressure applied when wearing the fascia and muscle adhesion release orthosis 1, the shape may be modified to omit the cylinder 50. Figure 5(d) shows the shape of the truncated cone 30 with the cylinder removed, and Figures 5(e) and (f) show the shapes of Figures 5(b) and (c) with the cylinder removed. Since there is no cylinder 50, the hook-and-loop fastener 60 is placed on the base surface of a truncated cone 30 or the like, and fixed to the band 10.

[0027] Thus, according to the present invention, adhesions between the medial and lateral heads of the gastrocnemius muscle can be effectively separated, thereby bringing the condition of the gastrocnemius muscle closer to a normal state and improving the pathological condition of foot and toe deformities.

[0028] Furthermore, the present invention allows for the separation of adhesions by wearing the orthotic device for a certain period of time. In addition, since the compression increases when performing daily activities that tend to cause adhesions while wearing the device, it becomes easier to identify the daily activities that cause adhesions.

[0029] Furthermore, this invention has the function of separating the points between the medial and lateral sides of the gastrocnemius muscle, transforming the gastrocnemius muscle into a muscle that is easier to pull upwards, thereby facilitating the shift of the center of gravity at the ankle joint and having the effect of loosening stiffened foot and toe muscles. By loosening the muscles, it is possible to promote the improvement of foot conditions such as ingrown toenails, bunions, and flat feet.

[0030] Furthermore, since the projection is detachable from the band, the shape of the projection can be changed according to changes in symptoms, etc., which is convenient. Furthermore, since the position where the protrusion is fixed to the band can be changed, the relative position of the protrusion and the folded-over ring during wear can also be changed, making it convenient for the patient to adjust the folded-over ring to a suitable position when wearing it.

[0031] Furthermore, in this invention, by using a ball base, the part that presses on the gastrocnemius muscle becomes more rounded, so the pressing force is distributed, and it can be used even for patients who are resistant to strong force.

[0032] Furthermore, according to the present invention, since the projection has a flat or nearly flat surface in the center, even if the projection is pressed hard, no sharp force is applied to the muscle, thus reducing the pain associated with compression.

[0033] Furthermore, because the diameter of the projection is larger than the width of the band, when the fascia and muscle adhesion release orthosis is attached to the lower leg, the position of the projection can always be known, making it convenient to easily detect and correct any misalignment. [Industrial applicability]

[0034] The fascia and muscle adhesion release orthosis according to the present invention has great industrial potential as an orthosis that efficiently resolves adhesions between the medial and lateral heads of the gastrocnemius muscle, which are factors that cause foot lesions.
