Abstract
Description
[0001] The invention relates to an orthopedic shoe insole. Orthopedic shoe insoles are inserted into a shoe to support the foot of the wearer. Various goals can be achieved by selecting a suitable shoe insole, such as correcting foot deformities, strengthening the muscles of the foot and leg, or protecting tendons and ligaments. This effect is achieved through the special design of the shoe insole. Shoe insoles typically have a shape that corresponds to the footbed of the respective shoe or at least to a part of the shoe. The upper surface of the shoe insole serves as a bearing surface for the foot.In order to achieve the beneficial effects for the foot, the upper surface has various elevations and depressions that correspond on the one hand to the anatomical structure of the foot, but on the other hand are also shaped in such a way that the desired supporting, muscle-activating or soothing effect occurs.
[0002] One type of shoe insole features areas designed exclusively for support. These areas primarily correct or prevent misalignments, thus relieving strain on muscles and tendons. Depending on which part of the foot is to be supported, the insole's surface has raised sections in various locations. A longitudinal arch support may be present on the inner side of the foot. There may also be a raised edge around the heel that extends to the outer side.
[0003] Another type of shoe insole features areas exclusively designed to have an activating effect. These areas are formed by raised sections of the insole surface that exert pressure on muscles or muscle attachments. This activates the corresponding muscles, thereby correcting any misalignment. Muscle activation can persist even after the insole is removed, thus contributing to long-term improvement. These sensorimotor areas of a shoe insole are typically less raised than supportive areas. Furthermore, the sensorimotor areas are usually limited to a small region to achieve near-point activation, often in the midfoot.
[0004] German patent application DE 10 2020 111 989 A1 describes a sensorimotor orthopedic shoe insole. It comprises a base body and at least two pressure modulators connected to the base body, which are intended to have a sensorimotor effect. The base body has a three-dimensional shape. The pressure modulators are each bonded to the base body and positioned in a recess formed by the base body.
[0005] German patent application DE 20 2017 101 877 A1 describes a ready-to-wear orthotic insole for positioning the human foot vertically. The insole has a base and a first sensorimotor elevation below the calcaneal plateau on the medial side of the foot, and a second sensorimotor elevation below the calcaneal plateau on the lateral side of the foot, the first sensorimotor elevation projecting higher above the base than the second sensorimotor elevation. The insole is designed as a brace, the posterior end of which terminates where the calcaneus forms the beginning of the arch, the anterior end of which terminates medially below the sesamoid bone of the first metatarsal bone, and the anterior end of which terminates laterally below the eminence of the fifth metatarsal bone.
[0006] DE 10 2006 044 026 A1 relates to a further shoe insole with three pads facing the sole of the foot and supporting it. They are oriented in such a way that they do not directly stress the plantar aponeurosis. This is intended to correct any deviation of the foot position from the normal foot posture during walking using the body's own sensorimotor system, and to allow the foot to return to the usual walking motion without requiring any conscious effort from the subject.
[0007] Another afferent-stimulating shoe insole, also called a proprioceptive or sensorimotor shoe insole, is described in DE 10 2021 126 214 A1. It is designed to enable the wearer to directly transmit ground reaction forces through the insole of a shoe to the sole of the foot in the area of specifically arranged edge recesses of a support layer, thereby allowing for targeted correction or stabilization of a physiologically desired gait pattern.
[0008] DE 20 2004 017 385 U1 shows a shoe insole intended to alleviate discomfort in the lumbosacral junction. DE 20 2020 000 645 U1 shows a shoe insole with tongue-shaped supports for the foot.
[0009] EP 3 960 133 B1 relates to an orthosis with a first and second raised section, wherein the first raised section increases the relief of the tibialis posterior muscle group and the second raised section stimulates the insertions and tendons of the peroneal muscle. The invention is said to have arisen because the inventor recognized the advantages of stimulating or blocking specific parts of the foot using targeted sections of an orthosis, thereby improving a person's movement pattern through enhanced activation of the neuromuscular complex.
[0010] Based on this state of the art, the object of the invention is to provide an orthopaedic shoe insole that has both a supportive and an activating effect and is characterized by simple manufacturability.
[0011] The problem is solved by an orthopaedic shoe insole according to claim 1. Advantageous embodiments are presented in the dependent claims and in the description.
[0012] The orthopaedic shoe insert has a top surface that serves as a support surface and extends longitudinally along the entire foot, a longitudinal arch support, and a sensorimotor-effective elevation, whereby • the sensorimotorically effective elevation has a highest point H1, which is located in the area of the calcaneus on the outside of the foot on a circumferential line of the upper surface and lies at least 10 mm higher in a first section plane perpendicular to the longitudinal direction passing through this highest point H1 than the lowest point T1 of the upper surface in this first section plane, • the sensorimotorically effective elevation extends so far towards the center of the foot that a first contour line 5 mm below the highest point H1 in the first section plane is at least half as far from the circumferential line in the lateral direction as the lowest point T1 and • the longitudinal arch support extends in the longitudinal direction over at least one third of the total length of the shoe insole and has a highest point H2, which is located in the area of the sustentaculum tali on the inside of the foot on the circumferential line of the top.
[0013] The orthotic insole has a contact surface formed by its upper surface, extending longitudinally along the entire length of the foot. The insole is designed to be placed inside a shoe and covers the entire length of the shoe's footbed. The orthotic effect of the insole is achieved primarily through longitudinal arch support and a sensorimotor elevation, each formed by corresponding elevations on the contact surface. Both the longitudinal arch support and the sensorimotor elevation have a highest point: point H1 for the sensorimotor elevation and point H2 for the longitudinal arch support. Points H1 and H2 are located on the outer and inner sides of the insole's circumference, respectively. From a top view, the circumference defines the contact surface and the upper surface of the insole.
[0014] The sensorimotor elevation extends from point H1, located on the circumferential line in the region of the calcaneus, far inwards towards the center of the contact surface. In a cross-sectional plane perpendicular to the longitudinal direction and passing through point H1, the distance between point H1 and the lowest point T1 on the upper surface is at least 10 mm vertically and, for example, at least 20 mm horizontally. Point T1 is located approximately in the center of the foot. Furthermore, the sensorimotor elevation extends towards the center of the foot to such an extent that a contour line running 5 mm below point H1 in the cross-sectional plane has a lateral distance to point H1, i.e., in the direction of point T1, that is at least half the distance between points H1 and T1.Preferably, the sensorimotorically effective elevation extends in the longitudinal direction so far that a contour line running 2.5 mm below point H1 has a front endpoint lying on the circumferential line and a rear endpoint lying on the circumferential line, which are 20 mm apart in the longitudinal direction.
[0015] The longitudinal arch support is distinguished by its high point H2, located far posteriorly. Point H2 lies on the circumferential line in the region of the sustentaculum tali. Furthermore, the longitudinal arch support is quite long, extending at least one-third of the total length of the shoe insole. Crucially, this is determined by the anterior extension of the longitudinal arch support from point H2. This extension can be measured using a second contour line positioned 10 mm below point H2. The anterior extension of the longitudinal arch support is the longitudinal distance between point H2 and the anterior endpoint of this additional contour line. This anterior endpoint can be located on the medial side of the foot along the circumferential line.
[0016] Because the sensorimotor elevation is positioned relatively far back on the foot, at the level of the heel bone, and extends well towards the center of the foot, it has a pronounced sensorimotor effect. This means that it specifically activates the peroneus longus muscle by applying pressure to the sole of the foot. Activating this muscle actively counteracts and corrects pronation of the foot. The activation effect can persist even after the shoe insert is no longer being worn. As a result, the wearer benefits from the positive effects of the orthotic shoe insert over a long period.
[0017] A further advantage is that the shoe insole according to the invention additionally features a particularly pronounced longitudinal arch support, which on the one hand provides support and on the other hand also activates the muscles in a sensorimotor way. Due to its exceptionally long shape, it supports the longitudinal arch of the foot, thus preventing it from collapsing. Because the longitudinal arch support also extends particularly far back, it also activates the tibialis posterior muscle in a sensorimotor way. This, too, counteracts misalignments, even when the shoe insole is no longer being worn.
[0018] A special feature of this shoe insole is that it activates sensorimotor muscles at two different points on the foot. This initiates a particularly strong and sustained activation process, effectively counteracting misalignments for an extended period. Simultaneously, it also provides support, especially for the longitudinal arch, ensuring a positive effect even in cases of severe misalignment or weak foot muscles. This combination of sensorimotor and supportive elements makes the orthotic insole exceptionally effective.
[0019] At the same time, the relatively simple design, which has no further embedded, bonded, or glued-on elements, allows the orthopaedic shoe insole according to the invention to be manufactured using simple means. It is not necessary to remove further cutouts from the surface into which, for example, sensorimotor modulators could be embedded.
[0020] In one embodiment, point H1 has a lower height and / or is located further back longitudinally than point H2. A particularly advantageous effect results when point H1 has a slightly lower height than point H2. This means that the sensorimotor-effective elevation extends less vertically than the longitudinal arch support. An improvement in the effect of the longitudinal arch support and the sensorimotor-effective elevation can also be achieved if point H1 is positioned further back longitudinally than point H2. This means that on the outer side, the sensorimotor-effective elevation is positioned slightly further back longitudinally than the longitudinal arch support on the inner side.
[0021] According to one embodiment, point H2 lies at least 15 mm higher in a second section plane perpendicular to the longitudinal direction, passing through point H2, than the lowest point T2 of the upper surface in the second section plane. The longitudinal arch support is particularly effective when it has a significant elevation relative to the inner part of the upper surface serving as the bearing surface. An elevation of 15 mm or more can be especially advantageous. This pronounced height difference exerts a correspondingly strong pressure on the inner side of the longitudinal arch, supporting it in such a way that it cannot collapse. This is particularly beneficial in the case of sagging and flat feet.
[0022] According to one embodiment, the longitudinal arch support extends towards the center of the foot such that a second contour line, 5 mm below point H2 in the second section plane, is at least one-quarter as far laterally from the second circumferential line as point T2. The effectiveness of the longitudinal arch support can be enhanced by extending it as far as possible towards the center of the foot. A second contour line, running 5 mm below point H2 in a section plane perpendicular to the longitudinal direction and passing through point H2, then has a lateral distance from point H2 to the circumferential line that is one-quarter of the distance between point H2 and point T2.Due to such a wide extension towards the middle of the foot, the arch of the foot is also subjected to pressure relatively far in the central area of the foot by the longitudinal arch support, which leads to sensorimotor activation.
[0023] According to one embodiment, the first contour line, viewed from above, maintains a distance from point H1 that is at least half the lateral distance between points H1 and T1. The beneficial effect of the sensorimotor elevation can be enhanced by extending it over as large a range as possible in the longitudinal direction. This is the case when the first contour line, which runs 5 mm below point H1, extends relatively far forward and backward from point H1 before ending at the perimeter. In particular, this is the case when the contour line, viewed from above, maintains a distance from point H1 that is at least half the lateral distance between points H1 and T1. Therefore, the contour line must maintain a minimum distance of 5 mm from H1.However, it can also extend significantly further inwards, so that a corresponding, sensorimotor-effective pressure is created further inside the foot.
[0024] According to one design, the first contour line, viewed from above, runs at least partially along a circle centered at point H1. The effect of the sensorimotor elevation is further enhanced by its circular shape when viewed from above. This is the case when the first contour line, viewed from above, runs at least partially along a circle centered at point H1. It is important to note that, extending from the first contour line, a portion of the sensorimotor elevation continues inwards, i.e., towards point T1. A first contour line positioned as far inwards as possible thus indicates that the sensorimotor elevation extends far towards the center of the foot.
[0025] According to one design, the first contour line has an endpoint located on the circumferential line. It is advantageous if the sensorimotor elevation does not form a continuous ridge on the outer side of the foot. In that case, it would primarily have a supporting effect and less of the desired effect of activating the muscles. Instead, it is advantageous if the elevation tapers off forwards and backwards after a certain distance along the longitudinal axis. This is particularly the case if the first contour line, which runs 5 mm below point H1, tapers off at a certain distance from point H1 on the circumferential line and has an endpoint there. Then the sensorimotorically effective elevation has a spatially limited elevation relative to the rest of the upper surface serving as the bearing surface.
[0026] According to one design, the upper surface between point H1 and the first contour line in the first section plane is convex. The sensorimotor effect can be enhanced by the sensorimotor elevation having a convex shape. This means that the slope decreases slowly at first and then more rapidly from point H1. This applies particularly to the area between point H1 and the first contour line, which is therefore convex.
[0027] According to one design, a raised, circumferential edge is present in the heel area. The effect of the sensorimotor elevation and the longitudinal arch support can be enhanced by this raised, circumferential edge in the heel area. This edge provides additional support for the foot, counteracting misalignments.
[0028] According to one design, a metatarsal pad is located in the midfoot area. A metatarsal pad in this area can help counteract splayfoot by activating the midfoot muscles. The presence of a metatarsal pad therefore enhances the positive effects of the orthotic shoe insert.
[0029] According to one design, the height of the top surface decreases continuously from point H1 to point T1 in the first section plane. A continuous surface without dents, craters, or similar defects promotes even pressure on the underside of the foot, resulting in a uniform and highly activating effect.
[0030] In one design, the shoe insole is manufactured as a single piece. When manufactured as a single piece, the surface topography is created through milling or injection molding. Both the sensorimotor elevation and the longitudinal arch support are then part of a single, unified body. The shoe insole can thus be manufactured in a single operation. Furthermore, such a one-piece shoe insole is robust because there are no breaks between different components that could predispose it to damage.
[0031] According to one design, the sensorimotor elevation and the rest of the shoe insole consist of two joined, particularly glued, pieces. This design involves at least two separate components, from which the entire shoe insole is then manufactured using a suitable joining process. The sensorimotor elevation is a separate component and can therefore be manufactured individually. Milling or manual machining are suitable methods for this. In any case, this allows for particularly precise manufacturing of the sensorimotor elevation's shape. Only then is this precisely manufactured sensorimotor elevation applied to the rest of the shoe insole. This can be done by gluing the sensorimotor elevation to the shoe insole. However, other joining methods are also possible.For example, the shoe insole could have a recess that allows for a form-fitting installation of the sensorimotor elevation. In this way, a shoe insole blank, which already has a longitudinal arch support in the design according to the invention, can be modified into the shoe insole according to the invention by means of an additional component. This also makes it easy to achieve a complex or particularly precisely defined shape for the sensorimotor elevation.
[0032] Preferably, the section forming the sensorimotorically effective elevation has a length of at least 30 mm, or even at least 40 mm. The length can refer in particular to the longitudinal direction in the assembled state or to the extent along the circumference in the assembled state.
[0033] According to one embodiment, the sensorimotor elevation, viewed from above, has an outer edge section whose course corresponds to the circumference and an inner edge section that is curved, in particular at least partially circular. The sensorimotor elevation is designed so that it fits seamlessly against the edge of the rest of the shoe insole. Accordingly, it has at least one outer edge section that follows the circumference. In such a case, the inward-facing edge of the sensorimotor elevation is curved. It may be at least partially circular. Viewed from above, the sensorimotor elevation appears almost semicircular in such a case. This shape allows for particularly good sensorimotor activation of the corresponding muscles.
[0034] In one design, the sensorimotor elevation has a different hardness than the rest of the shoe insole. This can be advantageous for achieving the desired muscle activation. This means that the shoe insole is made of a material with, for example, a high degree of hardness, whereas the sensorimotor elevation can be made of a material with a significantly lower or even a significantly higher degree of hardness. Depending on the wearer's weight, size, etc., a different gradient between the hardness of the shoe insole and the sensorimotor elevation can be used. The precise location of the sensorimotor elevation and the specific muscles to be activated can also be taken into account.
[0035] Preferably, the orthopaedic shoe insole is characterized in that the hardness of the remaining areas of the shoe insole is between 20 Shore and 55 Shore, preferably 30 Shore, and the hardness of the sensorimotor-active elevation is between 35 Shore and 55 Shore, preferably 45 Shore. These hardness levels enable most wearers to activate the muscles and support the foot without being uncomfortable.
[0036] The invention will now be explained in more detail using the embodiment shown in the drawings. The drawings show: Fig. 1 a view of a shoe insole according to the invention in a top view, Fig. 2 a sectional view in the area of a sensorimotor-effective elevation and
[0037] Fig. 3 a sectional view in the area of a longitudinal arch support. Fig. Figure 1 shows a top view of a shoe insole 1 according to the invention. The shape of the shoe insole 1 largely corresponds to the shape of a shoe's insole, and its upper surface provides a contact surface 2 for the foot inside the shoe. The contact surface 2 is bounded by the circumferential line 3. The contact surface 2 has areas of varying height, as indicated by the contour lines 4. The front area of the contact surface 2, which corresponds to the front of the foot, is lower than the rear area. This is also evident from the fact that there are more contour lines 4 in the rear of the shoe insole 1 than in the front. In the midfoot area, the shoe insole 1 also has a metatarsal pad 5, which is formed by a corresponding elevation. Furthermore, there is a raised, circumferential edge in the heel area of the rear of the foot.
[0038] On the outer side of the foot (i.e., on the left in the drawing), in the area of the calcaneus, there is a highest point H1 on the circumferential line 3, which corresponds to a sensorimotor elevation. The extent of the sensorimotor elevation associated with point H1 is approximately indicated by the dashed line 6. The fact that point H1 is elevated can be seen from the numerous contour lines in its vicinity. In the middle of the foot lies point T1, which is located on a line perpendicular to the longitudinal direction that passes through point H1. Point T1 represents the lowest point of the contact surface 2 along this line and lies at least 10 mm lower than point H1.
[0039] To achieve its sensorimotor activating effect, the sensorimotor elevation extends relatively far from point H1 towards the center of the foot, i.e., towards T1. This is evident from the fact that a first contour line 7, located 5 mm below point H1, maintains a distance from H1 along the connecting line between H1 and T1 that is at least half the distance between H1 and T1. The corresponding intersection of the connecting line between points H1 and T1 and contour line 7 is marked by point L1.
[0040] In this embodiment, the sensorimotor area 6 is formed integrally with the rest of the shoe insole 1. It is also possible to form area 6 from a separate piece, which, for example, has been milled to shape beforehand. After milling, the piece forming the sensorimotor elevation is then glued onto the rest of the shoe insole. In such a case, this piece would be bounded by a line that, viewed from above, looks approximately like the dashed line 6. Such a piece has a length of at least 30 mm along the circumferential line 3.
[0041] In addition to the sensorimotor elevation, the shoe insole 1 also features a longitudinal arch support, located approximately in the area marked by the dashed line 8. The longitudinal arch support is positioned on the inside of the foot (i.e., on the right side of the drawing) and is formed by a raised section. The highest point H2 of this raised section lies on the circumferential line 3 and is located longitudinally in front of point H1. Furthermore, point H2 is higher than point H1, as indicated by the additional contour lines. The corresponding lowest point T1 in the central area of the contact surface 2, which lies on a connecting line perpendicular to the longitudinal direction, is at a similar height to point T1 and has a vertical height difference a1 = 15 mm relative to H1.
[0042] The longitudinal arch support also extends relatively far towards the middle of the foot. This is indicated by a second contour line 9, located 5 mm below point H2, which, along a connecting line between points H2 and T2, has a distance from H2 that is approximately one-quarter of the distance between H2 and T2. The dashed line 8, in particular, shows that the longitudinal arch support is especially long, namely about one-third the total length of the shoe insert 1. The dashed line 8 largely follows the contour of contour line 7. This contour line is located 10 mm below point H2 and ends on the inner side at the circumferential line 3, just before point H2. The longitudinal distance between the endpoint of contour line 7 on the inner side and point H2 significantly contributes to the length of the longitudinal arch support.Because the longitudinal arch support extends over a relatively large area in both the longitudinal and transverse directions, and is located relatively far back on the foot, namely at the level of the sustentaculum tali, it has both a supporting and a sensorimotor activating effect.
[0043] The height profile of the sensorimotorically effective elevation and the longitudinal arch support is shown below in the Fig. 2 and Fig. 3 explained in more detail, whereby the Fig. 2 corresponds to a section perpendicular to the longitudinal direction, which is arranged on the section line AA, and which is in Fig. The section shown in section 3 is also arranged transversely to the longitudinal direction and runs along the section line BB.
[0044] Fig. Figure 2 shows the sectional view in the area of a sensorimotor-effective elevation along the in Fig. Section AA is shown in Figure 1. In this area, the shoe insole 1 has a horizontally oriented, flat underside and side walls arranged perpendicular to it, which therefore extend vertically. The upper surface is three-dimensionally shaped. It has the form of a valley, with the two highest points located on the outside and inside (i.e., left and right in the drawing) on the circumferential line 3, and a lower area extending between them. Point H1, which forms the highest part of the sensorimotorically effective elevation, is located on the outer edge of the foot (i.e., on the left in the drawing) on the circumferential line 3. The distance d1 between points H1 and T1 in the transverse direction is d1 = 20 mm. Point H1 has a height difference a1 compared to point T1, which is located in the middle of the foot. In this embodiment, the height difference a1 = 10 mm.
[0045] As previously explained, the sensorimotor elevation exerts its effect by extending relatively far into the midfoot. The contour line 7 and the point L1 located on it are also visible in this sectional view. The distance between points H1 and L1 is half the distance d1. Furthermore, the height difference between points H1 and L1 is half the height difference a1. The contact surface between points H1 and L1 is convex. A portion of the longitudinal arch elevation is visible in the right, i.e., inner, area of this section.
[0046] Fig. Figure 3 shows a corresponding sectional view in the area of the longitudinal arch support along the in Fig. Section line BB shown in Figure 1. The basic shape of the cross-section in this area corresponds to the valley shape of the previously discussed cross-section in Figure 1. Fig.2. However, the highest point H2 of the longitudinal arch support is located on the inside of the foot (i.e., on the right in the drawing) along the circumferential line 3. Point H2 is a distance d2 in the transverse direction from point T2, which is located in the middle part of the foot. In this embodiment, the distance d2 is 25 mm. Furthermore, point H2 has a height difference a2 in the vertical direction from point T2, where the height difference a2 = 15 mm. The height difference a2 is greater than the height difference a1, which means that the longitudinal arch support extends higher than the sensorimotorically effective elevation.
[0047] The view also shows point L2, which lies on the second contour line 9. Its transverse distance to H2 is one-quarter the size of distance d2, and its height difference to H2 is one-third the size of height difference a2. Thus, the longitudinal arch support is relatively high and extends relatively far into the midfoot.
[0048] The dimensions of the shoe insole in this example refer to a shoe insole in shoe size 39. For a shoe insole in a larger or smaller size, the dimensions may vary accordingly.
