Description

Article 30, Paragraph 2 of the Patent Act applies Date of publication: August 1, 2020 https://www. sk8insoll. tokyo/raiten https://tokyoinsoll. com/aimodel/

The present invention relates to an insole presentation system and an insole presentation method.

When walking or running in shoes, it has traditionally been customary to insert an insole into the sole of a shoe to improve the fit between the shoe and the foot and to absorb shock. It has also been proposed to acquire information about the shape of the foot and how the foot moves while walking, and create insoles suited to the unique foot shapes and walking movements of each individual (see, for example, Patent Documents 1-3).

The prior art technologies shown in Patent Documents 1 to 3 allow for the creation of custom-made or semi-custom-made insoles shaped to suit each individual, reducing the impact on the foot when walking and correcting posture to ensure proper walking. This is thought to prevent injuries and illnesses to joints and muscles caused by stress from walking and running.

However, the technologies disclosed in Patent Documents 1 and 2 involve wearing a dedicated pressure sensor device to measure the distribution of load on the sole of the foot. Such pressure sensor devices require specialized knowledge and proficiency in operation, including how to wear them, measure them, and maintain them, which poses a problem in that it is difficult for individual users or sales staff with little specialized knowledge to properly form insoles.

Furthermore, the technology disclosed in Patent Document 3 acquires data from various movements as comprehensive movement data or pentagonal movement data, and determines the convex shape of the insole near the big toe so as to correct the movement trajectory of the Center of Pressure (COP). However, the amount of data required is enormous, and it is necessary to perform multiple complex movements to acquire the data, which creates the problem of making it difficult to easily form the insole.

Furthermore, Patent Documents 1 to 3 aim to distribute the load on the sole of the foot using the insole shape, not to improve actual walking movements. Furthermore, even if the load on the sole of the foot is distributed using the insole shape, it is difficult to sufficiently improve walking movements, which are caused by a complex interplay of factors, or to sufficiently reduce the load on the body.

The present invention was developed in consideration of the above-mentioned conventional problems, and aims to provide an insole presentation system and method that allows the necessary data to be easily obtained through simple measurements, without requiring specialized measurement knowledge or mastery of device operation.

In order to solve the above problem, the insole presentation system of the present invention comprises a foot movement data acquisition unit that acquires foot movement data regarding the movement of the foot from the time of landing to the next time of landing when walking , and an insole presentation unit that presents an insole selected based on the foot movement data, wherein the insole is a combination of a base insole that covers the entire sole of the foot and a reinforcing insole that is placed at a predetermined position on the base insole, and the foot movement data includes at least two of the following: the degree of plantar flexion and dorsiflexion of the ankle joint, the degree of inversion and eversion of the ankle joint, and the degree of abduction and inversion of the ankle joint.

In the insole recommendation system of the present invention, an insole that is a combination of a base insole and a reinforced insole is selected based on foot movement data, making it possible to easily obtain the necessary data through simple measurements. Furthermore, specialized knowledge regarding measurements or mastery of device operation is not required.

In one aspect of the present invention, the foot movement data includes any one of the following: the degree of plantar flexion/dorsiflexion of the ankle joint, the degree of inversion/eversion of the ankle joint, and the degree of abduction/adduction of the ankle joint.

In one aspect of the present invention, a recommended exercise presentation unit is provided that presents recommended exercise information associated with the insole.

In one aspect of the present invention, the recommended exercise information includes one of a myofascial release method, a gait improvement method, and a training method.

In one aspect of the present invention, the foot movement data includes any one of the following: stride length, foot trajectory, foot lift height, foot swing speed, and widthwise distance between both feet.

In one aspect of the present invention, an attribute information acquisition unit is provided that acquires attribute information about a user of the insole, and the insole presentation unit presents the insole based on the attribute information.

In one aspect of the present invention, a shoe presentation unit is provided that presents shoe information associated with the insole.

In one aspect of the present invention, a foot shape data acquisition unit is provided that acquires foot shape data of the user of the insole, and the insole presentation unit presents the insole based on the foot shape data.

In order to solve the above problems, the insole presentation system of the present invention comprises a foot movement data acquisition unit that acquires foot movement data regarding foot movement from the time of landing to the next time of landing when walking , an insole presentation unit that presents an insole selected based on the foot movement data, and a recommended exercise presentation unit that presents recommended exercise information associated with the insole, and is characterized in that the insole is a combination of a base insole that covers the entire sole of the foot and a reinforcing insole that is placed at a predetermined position on the base insole.

In order to solve the above problem, the insole presentation method of the present invention comprises a foot movement data acquisition process for acquiring foot movement data regarding the movement of the foot from the time of landing to the next time of landing when walking , and an insole presentation process for presenting an insole selected based on the foot movement data, wherein the insole is a combination of a base insole that covers the entire sole of the foot and a reinforcing insole that is placed at a predetermined position on the base insole, and the foot movement data includes at least two of the following: the degree of plantar flexion and dorsiflexion of the ankle joint, the degree of inversion and eversion of the ankle joint, and the degree of abduction and inversion of the ankle joint.

In order to solve the above problem, the insole presentation method of the present invention is characterized by comprising a foot movement data acquisition step of acquiring foot movement data relating to foot movement from the time of landing to the next time of landing when walking , an insole presentation step of presenting an insole selected based on the foot movement data, and a recommended exercise presentation step of presenting recommended exercise information associated with the insole.

This invention provides an insole recommendation system that allows the necessary data to be easily obtained through simple measurements and does not require specialized measurement knowledge or mastery of device operation.

(First embodiment)
Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. The same or equivalent components, parts, and processes shown in each drawing will be denoted by the same reference numerals, and redundant description will be omitted where appropriate. FIG. 1 is a schematic diagram illustrating an overview of an insole presentation system 1000 according to this embodiment. As shown in FIG. 1, the insole presentation system 1000 includes an information acquisition device 100, an insole presentation device 200, and an insole selection device 300. Each device realizes various functions by executing a predetermined program on a computer equipped with a memory unit, an input unit, an output unit, a calculation unit, an information communication unit, etc., and is capable of mutual information communication. While FIG. 1 illustrates an example in which each device is configured with separate hardware and communicates information with each other via electrical information communication lines, multiple programs running on the same hardware configuration may function as each device. Furthermore, multiple functions may be realized on separate hardware configurations and function as each device in cooperation with each other.

The information acquisition device 100 is a device for acquiring information necessary for selecting an insole and transmitting the information to the insole selection device 300. In the example shown in FIG. 1, the information acquisition device 100 includes an attribute information acquisition unit 110, a foot shape data acquisition unit 120, and a foot movement data acquisition unit 130. Various information acquired by the information acquisition device 100 is transmitted to the insole selection device 300 by information communication means via an electrical information communication line or the like. The specific configuration of the information acquisition device 100 is not limited, and it may be an information processing device such as a personal computer or smartphone, or may be configured such that multiple devices are connected to each other so that they can communicate information with each other.

The attribute information acquisition unit 110 is a part that acquires attribute information about the insole user. The specific configuration of the attribute information acquisition unit 110 is not limited, and it may be configured to use an input device to input information into an input form displayed on the screen of an information processing device such as a personal computer or smartphone. Separately recorded information about the user may also be acquired by information communication means. Here, attribute information about the user may include age, gender, height, weight, medical history, exercise history, exercise habits, and exercise type.

The foot shape data acquisition unit 120 is a component that acquires foot shape data, which is information related to the shape of the insole user's foot. The specific configuration of the foot shape data acquisition unit 120 is not limited, and the foot shape data may be measured by capturing a foot shape using plaster or the like, and input using an information processing device. A conventional dedicated device for measuring foot shape data may also be used. Alternatively, a stereoscopic image of the foot may be captured using an imaging device or LiDAR (Light Detection and Ranging) device mounted on a smartphone or tablet, and foot shape data may be acquired using image recognition technology or three-dimensional measurement technology. Examples of foot shape data include the length from heel to toe, width, instep height, and contact surface shape. Foot shape data may be acquired with the foot on the ground and under load, or with the foot lifted from the ground and under no load.

The foot movement data acquisition unit 130 is a part that acquires foot movement data, which is information about foot movement, during the period when the insole user's feet are moving (foot movement period) while walking or running. The specific configuration of the foot movement data acquisition unit 130 is not limited, and a method can be used in which an acceleration sensor and gyro sensor are placed in the shoes used during the test walking to detect trajectory and tilt. One example is Senno Gait (registered trademark) manufactured by Sennotech. Alternatively, foot movement data can be acquired using motion capture technology or image recognition technology by capturing video of the foot movement using an imaging device or LiDAR device mounted on a smartphone or tablet.

Here, examples of foot movement data include the degree of plantar flexion and dorsiflexion of the ankle joint, the degree of inversion (pronation) and eversion (supination) of the ankle joint, the degree of inversion and eversion of the ankle joint, stride length, foot trajectory, foot lift height, foot swing speed, and the widthwise distance between the two feet. As will be described later in this embodiment, the degree of plantar flexion and dorsiflexion of the ankle joint, the degree of inversion and eversion of the ankle joint, and the degree of inversion and eversion of the ankle joint during the foot movement period are important as foot movement data.

The insole presentation device 200 is a device that receives information selected by the insole selection device 300 and presents it to the user. In the example shown in FIG. 1, the insole presentation device 200 includes an insole presentation unit 210 and a recommended exercise presentation unit 220. The insole presentation device 200 receives information about the insole selected by the insole selection device 300 and recommended exercise information from the insole selection device 300 via an electrical information communication line or the like using information communication means, and presents the information to the user. The specific configuration of the insole presentation device 200 is not limited, and various information processing devices such as computers and smartphones can be used. Furthermore, known information output means such as an image display device, audio guidance device, or paper printing device can be used as a method of presenting information.

The insole presentation unit 210 is a device that receives information about insoles suitable for the insole user selected by the insole selection device 300 and presents it to the insole user. The insole presentation unit 210 may also be equipped with online ordering means, etc., and may be provided with a function to access an online retailer connected via an electrical information communication line and order the presented insole online. The insole information presented by the insole presentation unit 210 will be described in detail below.

The recommended exercise presentation unit 220 is a device that receives recommended exercise information associated with the insole selected by the insole selection device 300 and presents it to the insole user. The recommended exercise presentation unit 220 may also transfer the recommended exercise information to other devices, such as exercise aids, and use it to control or adjust the operation of the exercise aids. In this embodiment, an example is shown in which the recommended exercise presentation unit 220 is provided in the insole presentation device 200, but the recommended exercise presentation unit 220 may be omitted. The recommended exercise information presented by the recommended exercise presentation unit 220 will be described in detail below.

The insole selection device 300 is a device that selects an insole suitable for the insole user based on information received from the information acquisition device 100 and transmits the selected insole to the insole presentation device 200. In the example shown in FIG. 1, the insole selection device 300 includes an attribute information database 310, a foot shape database 320, a foot movement database 330, an insole database 340, a recommended exercise database 350, an insole selection unit 360, and a recommended exercise selection unit 370. The specific configuration of the insole selection device 300 is not limited, and a server device equipped with storage means, information processing means, and information communication means can be used. While FIG. 1 shows an example in which the insole selection device 300 is configured as a device separate from the information acquisition device 100 and the insole presentation device 200, it may also be configured as the same hardware as these devices.

The attribute information database 310 is a section that records the attribute information of insole users acquired by the attribute information acquisition unit 110. The attribute information about users recorded in the attribute information database 310 is recorded in association with an identification number assigned to each user. The identification number is also associated with the footprint data recorded in the footprint database 320 and the foot movement data recorded in the foot movement database 330.

The insole selection unit 360 is a part that selects appropriate insole information from the insole database 340 based on the foot movement data acquired by the foot movement data acquisition unit 130, and transmits it to the insole presentation device 200. When selecting an insole, the insole selection unit 360 may also use attribute information and foot shape data associated with the same identification number.

The recommended exercise selection unit 370 is a unit that selects appropriate recommended exercise information from the recommended exercise database 350 based on the insole information selected by the insole selection unit 360 and transmits it to the insole presentation device 200. When selecting recommended exercises, the recommended exercise selection unit 370 may also use attribute information and foot shape data associated with the same identification number.

Figure 2 shows example databases in the insole presentation system 1000, with Figure 2(a) showing an example of the insole database 340 and Figure 2(b) showing an example of the recommended exercise database 350. The examples shown in Figure 2 are examples of the insole database 340 and the recommended exercise database 350, and each may include more items or more detailed information.

The insole information recorded in the insole database 340 includes information on the base insole 10, which covers the entire sole of the foot, and information on the reinforcing insoles 11-17, which are placed in predetermined positions on the base insole 10. The information on the base insole 10 also includes items such as shape, material, and thickness. The information on the reinforcing insoles 11-17 also includes multiple parts (e.g., parts A, B, C, etc.) and items such as shape, material, and thickness for each part. The information on the base insole 10 and the reinforcing insoles 11-17 may also include numerous items or more detailed information such as size, characteristics, and effects.

The recommended exercise information recorded in the recommended exercise database 350 includes multiple pieces of information on the areas to be stressed and the exercise characteristics. Furthermore, recommended exercises are associated with the information on each area to be stressed.

Examples of recommended exercises include myofascial release methods, gait improvement methods, and training methods.

Fascia release methods include massage and stretching methods to promote fascial stretching and improve range of motion in specific body parts. Gait improvement methods include how to use your toes, how to move your pelvis, head position, walking posture, and shifting your center of gravity on the soles of your feet. Training methods include exercises to strengthen muscles in specific body parts, stretching methods to increase the range of motion in specific body parts, and movement practice required for specific sports.

Figure 3 is a schematic diagram of an example of an insole presented by the insole presentation system 1000, with Figure 3(a) showing the base insole 10 and Figure 3(b) showing the reinforcing insoles 11-17. The base insole 10 has an outer shape that covers the entire sole of the foot and is inserted into the sole of the shoe to come into contact with the sole of the insole user. The reinforcing insoles 11-17 are attached to the underside of the base insole 10 (the side that faces the ground opposite the sole of the user's foot) at predetermined positions. The method of attaching the base insole 10 and the reinforcing insoles 11-17 is not limited, but a method of forming the base insole 10 and the reinforcing insoles 11-17 from a thermoplastic resin and then heat-pressing them together can be used. Alternatively, a method of applying an adhesive between the base insole 10 and the reinforcing insoles 11-17 to bond them together can also be used. By attaching the selected reinforcing insoles 11-17 to the underside of the base insole 10, an insole suitable for the insole user can be formed. Additionally, while an example has been shown in which the reinforcing insoles 11-17 are attached to the underside of the base insole 10, they may also be attached to the underside of the base insole 10.

As shown in Figure 3(a), the base insole 10 has an outer shape that covers the entire sole of the foot. Here, the entire sole preferably includes not only the area that the sole of the foot actually comes into contact with when the insole is inserted into the shoe, but also the plantar arch area that the sole does not come into contact with. By providing the base insole 10 to include the plantar arch area, etc., the reinforcing insoles 11-17 can be attached and held in place effectively. Furthermore, the strength and elasticity of the base insole 10 alone can be ensured.

As shown in Figure 3(b), the reinforcing insoles 11-17 are attached to the base insole 10 in predetermined positions. Figure 3(b) shows the reinforcing insoles 11-17 all attached together, but in an actual insole, parts selected from the reinforcing insoles 11-17 by the insole selection unit 360 are attached.

The reinforcing insoles 11-17 shown in Figure 3(b) are examples, and specific examples will be described below. Reinforcing insole 11 is positioned and shaped to cover the medial side of the calcaneus and the talus. Reinforcing insole 12 is positioned and shaped to cover the lateral side of the calcaneus and the lateral side of the cuboid. Reinforcing insole 13 is positioned and shaped to cover a wide area of the plantar arch. Reinforcing insole 14 is positioned and shaped to cover a narrow area of the plantar arch. Reinforcing insole 15 is positioned and shaped to fit along the middle phalanges of the big toe to the little toe. Reinforcing insole 16 is positioned and shaped to cover the ball of the foot. Reinforcing insole 17 is positioned and shaped to cover the sesamoid, proximal phalanges, middle phalanges, and distal phalanges of the big toe. The shapes and positions of reinforcing insoles 11-17 shown in Figure 3(b) are examples, and reinforcing insoles may include multiple parts, or multiple parts may be connected together to form a single unit.

As shown in Figure 3(b), reinforcing insoles 11-17 are attached to base insole 10 at predetermined positions, but they may also be attached to overlapping positions, such as the combination of reinforcing insoles 13 and 14, or the combination of reinforcing insoles 15, 16, and 17. Furthermore, multiple reinforcing insoles 11-17 may be stacked on top of each other. By stacking reinforcing insoles 11-17, the desired thickness and strength can be easily achieved.

Figure 4 is a diagram that schematically shows the degree of plantar flexion and dorsiflexion of the ankle joint contained in the foot movement data, with Figure 4(a) showing the angle at landing and Figure 4(b) showing the angle at push-off. In the diagram, the plane parallel to the contact surface is shown with a thick solid line, the ankle and toes are shown schematically, and the insole inserted into the sole is shown as a white plate. The direction perpendicular to the ground and the direction perpendicular to the insole are shown with dashed lines, respectively.

As shown in Figure 4(a), when landing during walking or running, the heel of the foot that has been moved forward lands first, and the sole of the foot then touches the ground in order toward the toes. At this time, body weight is applied to the sole, and the center of load moves forward within the plane of the sole. The angle between the direction perpendicular to the sole of the foot (insole) and the direction perpendicular to the ground contact surface during the movement of the foot is defined as θ1. The angle between the sole of the foot and the ground contact surface during the movement of the foot is defined as θ2. In this embodiment, the angles θ1 and θ2 between the heel and the ground contact surface during the movement of the foot are included in the foot movement data. Therefore, the foot movement data includes the degree of plantar flexion and dorsiflexion of the ankle joint, which can be calculated from angles θ1 and θ2.

As shown in Figure 4(b), when pushing off during walking or running, the foot remaining behind gradually leaves the ground surface from the heel to the toe. At this time, body weight is also applied to the sole of the foot, and the center of load moves forward within the plane of the sole. The angle between the direction perpendicular to the sole of the foot and the direction perpendicular to the ground surface during the movement of the foot is defined as θ3. The angle between the sole of the foot and the ground surface during the movement of the foot is defined as θ4. In this embodiment, the angles θ3 and θ4 between the toe and the ground surface during the movement of the foot are included in the foot movement data. Therefore, the foot movement data includes the degree of plantar flexion and dorsiflexion of the ankle joint, which can be calculated from angles θ3 and θ4.

Figure 5 is a schematic diagram showing foot trajectories included in foot movement data. The four footprints shown in the figure indicate the ground contact positions of the right and left feet when the insole user is walking or running. The trajectory of the right foot's movement in the air is shown by the solid curve TR, and the trajectory of the left foot's movement in the air is shown by the solid curve TL. The actual foot trajectories, curves TR and TL, are three-dimensional trajectories, as the foot remaining on the rear ground surface is raised, reaches its highest point as the foot moves forward, and the forward foot touches the ground. Furthermore, DR represents the distance between the left and right feet when the right foot is forward, and DL represents the distance between the left and right feet when the left foot is forward. Furthermore, W represents the widthwise distance between the left and right feet. In this embodiment, the foot movement data includes the curves TR, TL that represent the foot trajectories when walking or running, the ground contact distances DR, DL of the left and right feet in the front-to-back direction, and the ground contact distance W of the left and right feet in the width direction.

Figure 6 is a diagram showing the foot orientations included in the foot movement data, where Figure 6(a) shows pronation, Figure 6(b) shows supination, Figure 6(c) shows abduction, and Figure 6(d) shows adduction.

Figures 6(a) and (b) are views from the heel side of the left and right feet, and the thick solid lines in the figures indicate the talocrural joint, the direction of extension of the tibia, the direction of extension of the calcaneus, and the underside of the heel. Figure 6(a) shows the calcaneus extending downward from the talocrural joint opening outward and pronating (inward). Figure 6(b) shows the calcaneus extending downward from the talocrural joint closing inward and supinating (outward).

Figures 6(c) and (d) show the orientation of the soles of the left and right feet, with the solid straight lines in the figures indicating the direction extending from the heel to the center of the toes. Figure 6(c) shows a state in which the direction from the heel to the toes is turned outward and abducted. Figure 6(d) shows a state in which the direction from the heel to the toes is turned inward and adduction. In this embodiment, the degree of inversion/eversion of the ankle joint and the degree of abduction/inversion of the ankle joint are included in the foot movement data.

Figure 7 is a flowchart showing an example of the operation of the insole presentation method using the insole presentation system 1000. As shown in Figure 7, the insole presentation method of this embodiment includes an attribute information acquisition process, a foot shape data acquisition process, a foot movement data acquisition process, an insole selection process, an insole presentation process, a recommended exercise selection process, and a recommended exercise presentation process. In this embodiment, it is assumed that insole information is previously recorded in the insole database 340, and recommended exercise information is previously recorded in the recommended exercise database 350.

First, in the attribute information acquisition process of step S1, the attribute information of the insole user is acquired using the attribute information acquisition unit 110. As an example, the insole user inputs the attribute information using input means such as a mobile information terminal. The attribute information acquisition unit 110 accesses the insole selection device 300 via an electrical information communication line or the like, and records the acquired attribute information in the attribute information database 310 in association with the identification number. Furthermore, if the insole user is using the insole presentation system 1000 for the second or subsequent time, the attribute information acquisition unit 110 may access the insole selection device 300 via an electrical information communication line or the like and read the attribute information from the attribute information database 310. Here, an example is shown in which the insole user operates the attribute information acquisition unit 110 themselves, but the information acquisition device 100 may also be operated by a salesperson or counselor at an insole retailer.

Next, in the footprint data acquisition process of step S2, the footprint data acquisition unit 120 is used to acquire the insole user's footprint data. As an example, the insole user inputs footprint data measured using a tape measure or the like using input means such as a portable information terminal. The footprint data acquisition unit 120 accesses the insole selection device 300 via an electrical information communication line or the like, associates the acquired attribute information with an identification number, and records it in the footprint database 320. Furthermore, if the insole user is using the insole presentation system 1000 for the second or subsequent time, the footprint data acquisition unit 120 may access the insole selection device 300 via an electrical information communication line or the like, and read the footprint data from the footprint database 320. Here, an example is shown in which the insole user inputs the footprint data themselves, but the footprint data acquisition unit 120 may also be operated by a salesperson or consultant at an insole retailer.

Next, in the foot movement data acquisition process of step S3, the foot movement data acquisition unit 130 is used to acquire the insole user's foot movement data. As an example, a measuring device incorporating an acceleration sensor, gyro sensor, and short-range wireless communication is used. With the measuring device inserted into the sole, the insole user puts on the shoes and walks or runs. The measuring device acquires information such as the orientation of the sole, distance traveled, and angle over time, and transmits this information to the information acquisition device 100 via short-range wireless communication. The foot movement data acquisition unit 130 accesses the insole selection device 300 via an electrical information communication line, etc., and records the acquired foot movement data in the foot movement database 330 in association with an identification number. Measurements using the foot movement data acquisition unit 130 may be performed by the insole user themselves, or by a salesperson or consultant at an insole retailer.

Next, in the insole selection process of step S4, the insole selection unit 360 selects an appropriate base insole 10 from the insole database 340 based on the attribute information, foot shape data, and foot movement data associated with the identification number, and selects an appropriate combination from the reinforcing insoles 11-17. As an example, the insole selection unit 360 stores a matrix of the degree of association between the attribute information, foot shape data, and foot movement data for the base insole 10 and the reinforcing insoles 11-17. The insole selection unit 360 selects the base insole 10 and reinforcing insoles 11-17 with the highest degree of association from the attribute information, foot shape data, and foot movement data using the matrix. The insole selection unit 360 transmits information about the selected base insole 10 and reinforcing insoles 11-17 as insole information to the insole presentation unit 210 via an electrical information communication line. The insole selection unit 360 may also associate the insole information with the identification number and record it in the attribute information database 310.

Next, in the insole presentation process of step S5, the insole presentation unit 210 receives the insole information from the insole selection unit 360 and presents information about the selected insole to the operator of the insole presentation device 200. The operator of the insole presentation device 200 may be the insole user themselves, or a salesperson or counselor at an insole retailer. As an example, the shape, material, and thickness of the combination of the selected base insole 10 and the selected reinforcing insole 11-17 are displayed on an image display device. The combination of the selected base insole 10 and the reinforcing insole 11-17 may be displayed as a three-dimensional model on the image display device. Furthermore, instead of displaying the shape, material, and thickness, the model numbers of the selected base insole 10 and the reinforcing insole 11-17 may be displayed.

Next, in the recommended exercise selection process of step S6, the recommended exercise selection unit 370 selects appropriate recommended exercise information from the recommended exercise database 350 based on the insole information selected by the insole selection unit 360. Here, when selecting recommended exercise information, the recommended exercise selection unit 370 may also refer to the attribute information, foot shape data, and foot movement data associated with the identification number. As an example, the recommended exercise selection unit 370 records a matrix of the degree of association with recommended exercise information for the base insole 10 and the reinforcing insoles 11-17. From the selected insole information, the recommended exercise selection unit 370 selects the recommended exercise information with the highest degree of association from the matrix. The recommended exercise selection unit 370 transmits the selected recommended exercise information to the recommended exercise presentation unit 220 via an electrical information communication line. The recommended exercise selection unit 370 may also associate the recommended exercise information with the identification number and record it in the attribute information database 310.

Next, in the recommended exercise presentation process of step S7, the recommended exercise presentation unit 220 receives the recommended exercise information from the recommended exercise selection unit 370 and presents the selected recommended exercise information to the operator of the insole presentation device 200. The operator of the insole presentation device 200 may be the insole user themselves, or a salesperson or counselor at an insole retailer. As an example, the recommended exercise method, equipment to be used, fascia release method, etc. may be displayed on an image display device. Furthermore, actual movements of the recommended exercise may be displayed as a video. After the recommended exercise presentation process is completed, the insole presentation method of this embodiment ends.

As an example of the insole presentation method described above, we will explain a case where the foot shape data indicates hallux valgus on the right foot only, and the foot movement data indicates a small degree of plantarflexion and dorsiflexion at the ankle joint, resulting in inversion of the ankle joint. In the insole selection process, the shape of the heel cup of the base insole 10 is determined to match the shape of the heel so as to promote plantarflexion and dorsiflexion at the ankle joint and prevent inversion. Furthermore, because weight is applied to the right foot, which has hallux valgus, reinforcing insoles 11 and 12 are added to the heel of the left foot. Furthermore, reinforcing insoles 13 and 14 are added to raise the medial arch in order to relieve load on the head of the first metatarsal. Reinforcing insole 16 is added to activate mechanoreceptors so that the ball of the foot can be firmly pressed and kicked off the ground.

In the process of presenting recommended exercises, as the function of the posterior tibialis muscle is weakened, we suggest releasing the fascia of the posterior tibialis muscle using oil and a special tool specifically for fascia release. Furthermore, as the fascia of the entire sole of the foot is stiff, we suggest releasing the fascia of the sole of the foot using a special tool. We also present and instruct basic ankle and hip joint usage and walking techniques to effectively use the insoles. By performing these recommended exercises, it will become easier to plantarflex and dorsiflex the ankle joint, and to place weight on the entire sole of the foot.

As described above, insole information, which is a combination of base insole 10 and reinforcing insoles 11-17, is selected based on foot movement data, making it possible to easily obtain the necessary data through simple measurements. Furthermore, specialized knowledge of measurement or mastery of device operation is not required.

Furthermore, the above-mentioned foot movement data preferably includes any one of the following: the degree of plantar flexion/dorsiflexion of the ankle joint, the degree of inversion/eversion of the ankle joint, and the degree of adduction/abduction of the ankle joint. It is more preferable to combine two of the following into the foot movement data, the degree of plantar flexion/dorsiflexion of the ankle joint, the degree of inversion/eversion of the ankle joint, or the degree of adduction/abduction of the ankle joint, and even more preferably to combine all of them.

The inventors of the present application have discovered that selecting the base insole 10 and reinforcing insoles 11-17 based on foot movement data is important from the perspectives of reducing the strain on the body when walking or running, preventing falls while walking or running, and assisting recovery from a state of difficulty walking to being able to walk on one's own. In particular, they have discovered that the degree of plantar flexion and dorsiflexion of the ankle joint, the degree of ankle eversion and inversion, and the degree of ankle eversion and abduction are important among the foot movement data in order to easily and quickly obtain the information necessary for insole selection. They have also discovered that the time of landing is particularly important among the foot movement periods during which foot movement data is measured.

When walking or running, the foot repeatedly moves and the load shifts as shown in Figure 5, but the load on the foot moves from the heel toward the toes when the foot lands. Furthermore, the impact on the foot when walking or running is first felt at the heel and is greatest. Furthermore, the final point in the foot's trajectory when walking or running is when the foot lands, and the angle of the heel at the time of landing varies depending on the way the foot moves. Therefore, in order to select the optimal insole to reduce the burden on the body and promote appropriate foot movement, the degree of plantar flexion and dorsiflexion of the ankle joint is an important part of foot movement data.

The path that weight takes when it moves from the heel to the toes also differs depending on the degree of inversion/eversion of the ankle joint when landing. Furthermore, when weight is transferred after landing, it is transferred from the fibula and tibia to the talocrural joint and calcaneus, so the degree of inversion/eversion of the ankle joint affects the strain on the talocrural joint, knee joint, hip joint, etc. Therefore, the degree of inversion/eversion of the ankle joint is also extremely important when selecting the optimal insole to reduce strain on the body and promote proper foot movement.

The path that weight takes when it moves from the heel to the toes also differs depending on the degree of abduction/inversion of the ankle joint at the time of landing. Furthermore, when weight transfers after landing, the force exerted when the rear foot strikes the ground is transmitted from the sole of the foot to the fibula, tibia, talocrural joint, and calcaneus. Therefore, the degree of abduction/inversion of the ankle joint affects the strain on the talocrural joint, knee joint, hip joint, etc. Therefore, the degree of abduction/inversion of the ankle joint is extremely important when selecting the optimal insole to reduce strain on the body and promote proper foot movement.

In addition, the degree of plantar flexion and dorsiflexion of the ankle joint, the degree of inversion and eversion of the ankle joint, and the degree of abduction and adduction of the ankle joint can be obtained simply by measuring the angle of the sole of the foot, allowing for simple and quick measurements. Furthermore, even without directly measuring the load transfer on the sole of the foot, a combination of the degree of plantar flexion and dorsiflexion of the ankle joint, the degree of inversion and eversion of the ankle joint, and the degree of abduction and adduction of the ankle joint can be used to estimate load transfer or to substitute for load transfer data. This makes it possible to simply and quickly select a combination of an appropriate base insole 10 and an appropriate reinforcing insole 11-17.

Furthermore, by including stride length, foot trajectory, foot lift height, foot swing speed, and widthwise distance between the feet in the foot movement data, and further referencing this data, it is possible to select an insole that is even more precise.

In addition, by presenting recommended exercise information associated with the insole using the recommended exercise presentation unit 220, it is possible to advise the insole user on exercises suitable for walking or running in order to achieve appropriate walking or running. This not only assists walking or running through the combination of the base insole 10 and the reinforcing insoles 11-17, but also encourages the insole user to adopt a walking posture and method that is less likely to cause falls and that reduces the burden on the joints, thereby helping to prevent injury and illness.

In addition, by including myofascial release methods, gait improvement methods, and training methods in the recommended exercise information, it is possible to provide appropriate rehabilitation information to elderly people and those with walking difficulties, and to provide information useful for preventing injury and improving athletic performance to athletes participating in specific sports.

In addition, the attribute information acquisition unit 110 acquires attribute information about the insole user, and by using this attribute information when the insole selection unit 360 selects a combination of the base insole 10 and the reinforcing insoles 11-17, it is possible to select and present more appropriate insoles that take the insole user's attributes into account.

Furthermore, by acquiring foot shape data using the foot shape data acquisition unit 120 and using the foot shape data when the insole selection unit 360 selects a combination of the base insole 10 and the reinforcing insoles 11-17, it is possible to select and present more appropriate insoles taking into account the foot shape of the insole user.

As described above, in the insole presentation system 1000 and insole presentation method of this embodiment, insole information, which is a combination of the base insole 10 and the reinforcing insoles 11-17, is selected based on foot movement data, making it possible to easily obtain the necessary data through simple measurements. Furthermore, specialized knowledge regarding measurements or mastery of device operation is not required.

Second Embodiment
Next, a second embodiment of the present invention will be described. Details that overlap with those of the first embodiment will not be described. In the first embodiment, an example was shown in which the insole selection unit 360 selected a combination of the base insole 10 and the reinforcing insoles 11 to 17 based on the degree of association between the attribute information, foot shape data, and foot movement data recorded in the matrix. However, in this embodiment, the selection is based on a predetermined relationship.

As one example, foot movement data serving as a target value is pre-recorded in the insole selection unit 360 as target data, and the difference between the insole user's foot movement data and the target data is calculated, and a combination of base insole 10 and reinforcing insole 11-17 is selected based on the difference. As a more specific example, if the target data for the degree of plantar flexion and dorsiflexion of the ankle joint is X degrees and the degree of plantar flexion and dorsiflexion of the ankle joint acquired by the foot movement data acquisition unit 130 is Y degrees, a combination of base insole 10 and reinforcing insole 11-17 is selected based on the difference (X-Y) degrees. Similarly, for the degree of ankle eversion/eversion and the degree of ankle abduction/inversion, the difference between the target data and the measured value is calculated and used for insole selection. Alternatively, instead of pre-recording target data, the average value of the foot movement data measurements of multiple insole users may be used as the target data.

(Third embodiment)
Next, a third embodiment of the present invention will be described. Description of content overlapping with the first and second embodiments will be omitted. In this embodiment, the attribute information acquisition unit 110 acquires health condition history information representing the current health condition, and records the identification number and the health condition history information in association with each other in the attribute information database 310.

The attribute information database 310 stores attribute information, foot shape data, foot movement data, information on the presented insoles, and information on the presented recommended exercises, all associated with an identification number. Therefore, by recording health condition history information in the attribute information database 310, it is possible to analyze the use of insoles and recommended exercises, as well as the health condition history.

The insole selection unit 360 and the recommended exercise selection unit 370 use machine learning to analyze the relationships between the attribute information, foot shape data, foot movement data, presented insole information, presented recommended exercise information, and health condition history information recorded in the attribute information database 310, and can refer to the analysis results obtained through this machine learning when selecting a combination of base insole 10 and reinforcing insole 11-17 from the next time onwards. This makes it possible to further enhance the effectiveness of using insoles and recommended exercises in preventing injuries, illnesses, and declines in athletic ability.
