In determining the position (1), when the rib bulge is displaced outward (the fifth metatarsal side, that is, the little finger side in FIG. 2), the amount (the amount displaced outward) is measured. The position is set as possible. Normally, if the rib bulge is displaced, it is on the outside of the foot (the little finger side) and does not come off the inside of the foot (the first metatarsal side, that is, the thumb side in FIG. 2).

Description

足裏計測装置Foot measuring device
 本発明は、人間の足裏の特定の部位に作用する力(例えば圧力、せん断力)を計測する装置に関する。 The present invention relates to an apparatus for measuring a force (for example, pressure, shearing force) acting on a specific part of a human foot sole.
 人間の足裏の特定の部位に作用する圧力を測定して、所謂「足圧分布」を特定することにより、足裏で最も荷重が加わる位置を推定し、変形性膝関節症や外反拇指のリスク評価を行なうことが出来る。
 しかし、従来技術では人間の足裏の特定の部位に作用する圧力を測定するのに大型な装置が必要となり、被測定者に余計なストレスを与えてしまい、正確な計測が困難になる恐れがある。
 また、足裏圧力測定は運動している中で(例えば歩行中に)計測することが必要であるが、従来の機器では歩行中の足裏圧力測定が困難である。そのため、静止した状態で足裏圧力を計測し、静止した状態の足裏圧力から歩行中の足裏圧力を推定するしかないのが実情である。
By measuring the pressure acting on a specific part of the human foot and identifying the so-called “foot pressure distribution”, the position where the most load is applied on the sole is estimated, and knee osteoarthritis and hallux valgus Risk assessment.
However, in the prior art, a large device is required to measure the pressure acting on a specific part of the human foot, which may cause extra stress on the person being measured and may make accurate measurement difficult. is there.
In addition, although it is necessary to measure the sole pressure while exercising (for example, during walking), it is difficult to measure the sole pressure during walking with conventional devices. Therefore, the actual situation is that the sole pressure is measured in a stationary state, and the sole pressure during walking is estimated from the sole pressure in a stationary state.
 さらに足、脚の異常は、変形性膝関節症や外反拇指以外にも各種存在するが、変形性膝関節症や外反拇指以外の異常を判定するには足圧分布以外のパラメータが必要である。しかし、従来はその様なパラメータは提案されていなかった。
 その他の従来技術として、シート式の圧力センサを用いて歩行能力を評価する技術が存在する(特許文献1参照)。しかし、係る従来技術(特許文献1)では、シート式圧力センサを設置するのに大きな面積が必要であり、また、各種疾患を判定する技術に適用することが出来ない。
In addition, there are various types of abnormalities in the legs and legs other than knee osteoarthritis and hallux phalanges, but parameters other than foot pressure distribution are necessary to determine abnormalities other than knee osteoarthritis and hallux phalanges. It is. However, no such parameter has been proposed in the past.
As another conventional technique, there is a technique for evaluating walking ability using a seat-type pressure sensor (see Patent Document 1). However, the related art (Patent Document 1) requires a large area for installing the seat type pressure sensor, and cannot be applied to a technique for determining various diseases.
特開2014-94070号公報JP 2014-94070 A
 本発明は上述した従来技術の問題点に鑑みて提案されたものであり、計測装置を小型化して、且つ、運動している状態(例えば歩行中)における人間の足裏の特定の部位に作用する力(例えば圧力、せん断力)を計測することが出来て、しかも、足圧分布以外のパラメータを決定することが出来る足裏計測装置の提供を目的としている。 The present invention has been proposed in view of the above-described problems of the prior art, and has a function of reducing the size of a measuring device and acting on a specific part of a human foot sole while in motion (for example, while walking). An object of the present invention is to provide a sole measuring device that can measure a force (for example, pressure, shearing force) to be performed and can determine parameters other than a foot pressure distribution.
 本発明の足裏計測装置(100)は、足の裏が接触する部材(10:例えばインソール、靴)の踵骨***部(位置1)、立方骨(位置2)、第五中足骨頭(位置3)、第一中足骨頭(位置5)、中間楔状骨(位置6)、横足弓中心(位置7)に対応する位置(図2のL(1)、R(1)、L(2)、R(2)・・・・L(7)、R(7):図2の(1)~(7))にセンサ(せん断力センサ、圧力センサ)を設けたことを特徴としている。 The sole measuring device (100) of the present invention includes a rib raised portion (position 1), a cubic bone (position 2), and a fifth metatarsal head (10 Position 3), first metatarsal head (position 5), intermediate wedge bone (position 6), positions corresponding to the lateral foot arch center (position 7) (L (1), R (1), L ( 2), R (2)... L (7), R (7): (1) to (7) in FIG. 2 are provided with sensors (shear force sensors, pressure sensors). .
 また本発明において、拇指接地面(図1のL(4)、R(4):図2の(4))にセンサを設けることが好ましい。
 そして本発明において、踵骨***部(位置1)、立方骨(位置2)、第五中足骨頭(位置3)、拇指接地面(位置4)、第一中足骨頭(位置5)、中間楔状骨(位置6)、横足弓中心(位置7)に対応する位置に設けられたセンサ1~7の出力を解析装置(20)に対して無線で送信するのが好ましい。
In the present invention, it is preferable to provide a sensor on the thumb contact surface (L (4), R (4): FIG. 2 (4) in FIG. 1).
In the present invention, the rib raised portion (position 1), the cubic bone (position 2), the fifth metatarsal head (position 3), the thumb contact surface (position 4), the first metatarsal head (position 5), the middle The outputs of the sensors 1 to 7 provided at the positions corresponding to the wedge bone (position 6) and the lateral foot arch center (position 7) are preferably transmitted wirelessly to the analysis device (20).
 本発明の実施に際して、位置踵骨***部(位置1)、立方骨(位置2)、第五中足骨頭(位置3)、第一中足骨頭(位置5)、横足弓中心(位置7)に設けられるセンサはせん断力センサであるのが好ましい。 In carrying out the present invention, the position rib ridge (position 1), the cubic bone (position 2), the fifth metatarsal head (position 3), the first metatarsal head (position 5), the lateral foot arch center (position 7). ) Is preferably a shear force sensor.
 上述の構成を具備する本発明の足裏計測装置(100)によれば、靴或いはソール等(10)の足裏と接触する部材にセンサを設けるだけで構成することが出来るので、装置全体を小型化することが出来る。
 そのため、大型装置の様に被測定者に余計なストレスを与えてしまうことはなく、そのため、正確な計測が可能である。また、小型化された装置であれば、運動している中で(例えば歩行中に)、上述した位置に作用する力(せん断力或いは圧力)を直接計測することが可能になる。従来技術の様に、静止した状態の足裏圧力から歩行中の足裏圧力を推定する必要はない。
 特に、本発明においてセンサの出力を解析装置(20)に対して無線で送信すれば、運動中における動きの解析が容易に行われる。
According to the sole measuring device (100) of the present invention having the above-described configuration, it can be configured only by providing a sensor on a member that comes into contact with the sole of the shoe or sole (10). It can be downsized.
Therefore, it does not give extra stress to the person being measured like a large-sized device, and therefore accurate measurement is possible. In addition, if the device is downsized, it is possible to directly measure the force (shearing force or pressure) acting on the above-described position while exercising (for example, during walking). Unlike the prior art, it is not necessary to estimate the sole pressure during walking from the sole pressure in a stationary state.
In particular, if the sensor output is wirelessly transmitted to the analysis device (20) in the present invention, analysis of movement during exercise is easily performed.
 また本発明では、踵骨***部(位置1)、立方骨(位置2)、第五中足骨頭(位置3)、第一中足骨頭(位置5)、中間楔状骨(位置6)、横足弓中心(位置7)と対応する位置にセンサを設けているので、足の重心点、アーチ、足の骨軸を決定することが出来る。
 そして、足の重心点の軌跡である「足の重心線」も容易に求めることが出来る。
 足の重心線、アーチ(横アーチ、縦アーチ、外アーチ)、足の骨軸を決定することにより、変形性膝関節症や外反拇指以外の各種異常を判断して、当該異常を矯正或いは抑制する様な器具、運動を提案することが可能である。特に、小学生、中学生の様に成長途中の段階であれば、上述した様な運動や器具により、各種異常が解消され、正常な状態になる可能性が高い。
 そして、変形性膝関節症や外反拇指以外の各種異常を判断するパラメータとして、足の重心線、アーチ、足の骨軸という足圧分布以外のパラメータを用いることが出来る。
In the present invention, the rib raised portion (position 1), the cubic bone (position 2), the fifth metatarsal head (position 3), the first metatarsal head (position 5), the intermediate wedge bone (position 6), the lateral bone Since the sensor is provided at a position corresponding to the center of the foot arch (position 7), the center of gravity of the foot, the arch, and the bone axis of the foot can be determined.
Then, the “foot barycentric line” that is the trajectory of the barycentric point can be easily obtained.
By determining the center of gravity line of the foot, arch (lateral arch, vertical arch, external arch), and bone axis of the foot, various abnormalities other than knee osteoarthritis and hallux valgus are determined, and the abnormality is corrected or It is possible to propose a device or exercise that can be suppressed. In particular, at the stage of growth like elementary school students and junior high school students, there is a high possibility that various abnormalities will be resolved and the normal state will be obtained by the exercise and equipment described above.
As parameters for determining various abnormalities other than knee osteoarthritis and hallux phalanges, parameters other than foot pressure distribution such as foot center of gravity, arch, and foot bone axis can be used.
 ここで、拇指接地面(位置4)における圧力値が大きい場合には、歩行に際して足指が有効に使われており、地面を蹴り出す力が大きいことを意味している。従って、その他の条件が同じであれば、拇指接地面(位置4)における圧力値が大きい場合には、歩幅が大きく、歩行速度が速く、クリアランス(歩行中のつま先と接地面との距離)も大きいことになる。そのため、歩行が安定しており、歩行時の転倒の危険性が少ない。
 本発明において、拇指接地面(位置4)にセンサを設けた場合には、当該センサ(位置4)の計測結果から、歩行機能が判定され、歩行時に転倒する可能性を判断することが出来る。
Here, when the pressure value on the thumb contact surface (position 4) is large, it means that the toes are used effectively during walking and the force to kick the ground is large. Therefore, if other conditions are the same, when the pressure value on the thumb contact surface (position 4) is large, the stride is large, the walking speed is fast, and the clearance (the distance between the toe and the contact surface during walking) is also large. It will be big. Therefore, walking is stable and there is little risk of falls during walking.
In the present invention, when a sensor is provided on the thumb contact surface (position 4), the walking function is determined from the measurement result of the sensor (position 4), and the possibility of falling during walking can be determined.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
FIG. 1 shows an overview of an embodiment of the present invention.
The sole measuring device 100 of the present invention according to the embodiment is generally indicated by reference numeral 100 in FIG. 1, and includes an insole 10 (or shoes) that is a member that contacts the sole of the foot, an analysis device 20, and a display. The apparatus 30 and the determination apparatus 40 are included.
The insole 10 (or shoes) is composed of an insole 10R for the right foot and an insole 10L for the left foot, and in each of the insole 10R, 10L, seven predetermined positions (R1) to (R7), (L1) to (L7). ) Are provided with sensors R1 to R7 and L1 to L7. In FIG. 1, the “predetermined position” or the “sensor” installed at the predetermined position is represented by the same reference numeral, and is indicated by reference numerals (R1) to (R7) and (L1) to (L7), respectively. ing.
 各センサR1~R7、L1~L7による計測結果は、それぞれ無線により解析装置20に送信される。図1では各センサを代表して、センサR1、L1から解析装置20に計測結果が無線送信される態様を、矢印SR1、SL1(無線信号ライン)で示している。
 なお、各センサR1~R7、L1~L7から解析装置20にそれぞれの計測結果を送信するに際して、有線で行うことも可能である。
The measurement results obtained by the sensors R1 to R7 and L1 to L7 are transmitted to the analysis device 20 by radio. In FIG. 1, as an example of each sensor, arrows SR <b> 1 and SL <b> 1 (wireless signal lines) indicate how the measurement results are wirelessly transmitted from the sensors R <b> 1 and L <b> 1 to the analysis device 20.
It should be noted that, when the respective measurement results are transmitted from the sensors R1 to R7 and L1 to L7 to the analysis device 20, they may be performed by wire.
 解析装置20による解析結果は、情報信号ラインIL9を介して表示装置30に送信される。
 また、解析装置20により処理された結果(解析結果)は情報信号ラインIL10を介して判定装置40に送信され、表示装置30の画像データも情報信号ラインIL12を介して判定装置40に送信される。

Further, the result (analysis result) processed by the analysis device 20 is transmitted to the determination device 40 via the information signal line IL10, and the image data of the display device 30 is also transmitted to the determination device 40 via the information signal line IL12. .
The determination device 40 determines and presents the necessary countermeasure content based on the analysis result of the analysis device 20 and the image data of the display device 30.
 次に、センサR1~R7、L1~L7の設置位置について、図2を参照して説明する。
 図2では、右足(右足用のインソール10R或いは靴におけるセンサ(1)~(7)の位置)について示しているが、左足或いは左足用のインソール10L(或いは靴)におけるセンサの位置は、図2で示す位置と左右対称の位置である。
 センサ1~7(センサR1~R7であるが、煩雑さを避けるため、以下「センサ1~7」と記載する)は、人の足の側部の骨格構造からその位置が定義される。そのため、図2では右足の骨格を示している。
Next, the installation positions of the sensors R1 to R7 and L1 to L7 will be described with reference to FIG.
FIG. 2 shows the right foot (the position of the sensors (1) to (7) in the insole 10R for the right foot or the shoe), but the position of the sensor in the insole 10L (or the shoe) for the left foot or the left foot is shown in FIG. It is a position symmetrical to the position indicated by.
The positions of the sensors 1 to 7 (sensors R1 to R7, which are hereinafter referred to as “sensors 1 to 7” for the sake of simplicity) are defined from the skeleton structure of the side of the human foot. Therefore, FIG. 2 shows the skeleton of the right foot.
 センサ1が配置される位置(図2では符号(1)で示す)は踵骨***部である。より望ましくは、位置(1)は踵の骨の中心部である。
 また、位置(1)を決定するに際しては、踵骨***部が外側(図2で第五中足骨側、すなわち小指側)にずれた際に、その量(外側にずれた量)を計測出来る様な位置に設定される。通常、踵骨***部がずれてしまうとすれば足の外側(小指側)であり、足の内側(図2で第一中足骨側、すなわち親指側)にはずれない。
 センサ2が配置される位置(図2の符号(2)で示す位置)は、立方骨に対応する位置である。但し、立方骨の中心よりもやや外側(小指側:第五中足骨の領域)であっても良い。
The position where the sensor 1 is disposed (indicated by reference numeral (1) in FIG. 2) is the rib bulge. More preferably, position (1) is the center of the heel bone.
In determining the position (1), when the rib bulge is displaced outward (the fifth metatarsal side, that is, the little finger side in FIG. 2), the amount (the amount displaced outward) is measured. The position is set as possible. Normally, if the rib bulge is displaced, it is on the outside of the foot (the little finger side) and does not come off the inside of the foot (the first metatarsal side, that is, the thumb side in FIG. 2).
The position where the sensor 2 is arranged (the position indicated by the reference numeral (2) in FIG. 2) is a position corresponding to the cubic bone. However, it may be slightly outside the center of the cubic bone (the little finger side: the region of the fifth metatarsal bone).
 センサ3が配置される位置(図2では符号(3)で示す)は、第五中足骨頭に対応する位置である。
 歩行時の状態を解析するためには、「歩行時に体重が掛かる箇所」に作用する力を計測する必要がある。第五中足骨の付け根である第五中足骨頭は、「歩行時に体重が掛かる箇所」である。
 ここで、センサ3が配置される位置が第五中足骨頭の長さの1/3程度、つま先とは反対側にずれたとしても、「歩行時に体重が掛かる箇所」に作用する力を計測出来るので問題はない。
 ただし、第五末梢骨(つま先側の骨)には体重が掛からないので、第五中足骨頭よりも第五末梢骨側(つま先側)にずれた位置にセンサを取り付けることは不都合である。
The position where the sensor 3 is disposed (indicated by reference numeral (3) in FIG. 2) is a position corresponding to the fifth metatarsal head.
In order to analyze the state at the time of walking, it is necessary to measure the force acting on the “location where weight is applied during walking”. The fifth metatarsal head, which is the root of the fifth metatarsal, is a “location where weight is applied during walking”.
Here, even if the position where the sensor 3 is arranged is about 1/3 of the length of the fifth metatarsal head and deviates to the side opposite to the toes, the force acting on “the place where weight is applied during walking” is measured. There is no problem because it can be done.
However, since the fifth peripheral bone (toe side bone) does not bear weight, it is inconvenient to attach the sensor to a position shifted to the fifth peripheral bone side (toe side) from the fifth metatarsal head.
 センサ4が配置される位置(図2では符号(4)で示す)は、拇指接地面、すなわち拇指の先端部で歩行の際に地面に着く領域である。
 歩行の際の蹴り出しの強さを求めるのに、位置(4)に作用する力を計測する必要があることによる。
 ここで、骨(第一末梢骨)が足の親指のどの部分まで伸びているのかについては、個人差がある。そのため、位置(4)は骨の名称で特定するのではなく、上述した様に「拇指接地面」として特定している。
 センサ4の位置が拇指接地面を外れてしまうと、歩行の際の蹴り出しの強さを計測できないので、不都合である。
 後述するが、「足の骨軸」、「アーチ」、「重心線」を特定(決定)するのには、位置(4)に配置したセンサ4の計測結果は用いない。
The position at which the sensor 4 is disposed (indicated by reference numeral (4) in FIG. 2) is a region that reaches the ground when walking on the thumb contact surface, that is, the tip of the thumb.
This is because the force acting on the position (4) needs to be measured in order to obtain the kicking strength during walking.
Here, there are individual differences as to which part of the big toe the bone (first peripheral bone) extends. Therefore, the position (4) is not specified by the name of the bone, but is specified as the “finger ground contact surface” as described above.
If the position of the sensor 4 deviates from the thumb contact surface, it is inconvenient because the strength of kicking out during walking cannot be measured.
As will be described later, the measurement results of the sensor 4 arranged at the position (4) are not used to specify (determine) the “foot bone axis”, “arch”, and “center of gravity”.
 センサ5が配置される位置(図2で符号(5)で示す)は、第一中足骨頭に対応する位置である。
 歩行時に体重がかかるのが第一中足の骨頭側、いわゆる「拇指球」の部分である。そのため、センサ5の取付位置は、「拇指球」から外れないようにする必要がある。拇指球に体重が掛かるからである。
The position where the sensor 5 is disposed (indicated by reference numeral (5) in FIG. 2) is a position corresponding to the first metatarsal head.
It is the so-called “thumb ball” part of the first metatarsal side that weighs during walking. For this reason, it is necessary to prevent the sensor 5 from being attached to the “finger ball”. This is because the ball ball takes weight.
 センサ6が配置される位置(図2では符号(6)で示す位置)は、中間楔状骨に対応する位置である。
 センサ6が配置される位置は、センサ1を配置した位置(1)から第二指(人差し指)を結ぶ直線Lαと、位置(1)から第四指(薬指)を結ぶ直線Lβとで挟まれた領域における3つの楔状骨の領域であれば良い。
 ここで、位置(1)と第二指(人差し指)を結ぶ直線Lαよりも親指側の領域は、土踏まずになってしまう可能性があるため、センサ6を設置するのは不都合である。一方、位置(1)と第四指(薬指)とを結ぶ直線Lβよりも小指側の領域は、位置(2)と重複してしまう可能性があるため、やはりセンサ6を設置するのは不都合である。これ等の理由により、センサ6の配置位置は上述の様に決定されている。
The position where the sensor 6 is disposed (the position indicated by reference numeral (6) in FIG. 2) is a position corresponding to the intermediate wedge bone.
The position where the sensor 6 is arranged is sandwiched between a straight line Lα connecting the second finger (index finger) from the position (1) where the sensor 1 is arranged and a straight line Lβ connecting the fourth finger (ring finger) from the position (1). What is necessary is just the area of three wedge-shaped bones in the area.
Here, it is inconvenient to install the sensor 6 because the region closer to the thumb than the straight line Lα connecting the position (1) and the second finger (index finger) may become an arch. On the other hand, since the region on the little finger side of the straight line Lβ connecting the position (1) and the fourth finger (ringing finger) may overlap with the position (2), it is also inconvenient to install the sensor 6. It is. For these reasons, the arrangement position of the sensor 6 is determined as described above.
 図3を参照して後述する様に足のアーチには縦アーチAR1、外アーチAR2、横アーチAR3の3種類がある。縦アーチAR1は、図2で踵骨***部を表す位置(1)の近傍から第一中足骨頭を表す位置(5)の近傍まで延在しており、外アーチAR2は、図2で踵骨***部を表す位置(1)の近傍から第五中足骨頭を表す位置(3)の近傍まで延在している。さらに横アーチAR3は、図2で第一中足骨頭を表す位置(5)の近傍から第五中足骨頭を表す位置(3)の近傍まで延在している。アーチAR1~3により、歩行時などに足裏に係る衝撃を吸収することができる。
 足のアーチを特定するためには、位置(2)、(6)以外の位置(例えば、位置(1)、(3)等)における計測結果を併せて参照する必要がある。
 また、位置(6)と位置(2)の計測結果(及びその他の位置(1)、(3)等の計測結果と併せて)から、重心点(瞬間における足裏の圧力中心:重心点の軌跡が「重心線」)が特定(決定)出来る。
As will be described later with reference to FIG. 3, there are three types of foot arches: a longitudinal arch AR1, an outer arch AR2, and a lateral arch AR3. The longitudinal arch AR1 extends from the vicinity of the position (1) representing the rib bulge in FIG. 2 to the vicinity of the position (5) representing the first metatarsal head, and the outer arch AR2 is the heel in FIG. It extends from the vicinity of the position (1) representing the bone protuberance to the vicinity of the position (3) representing the fifth metatarsal head. Further, the lateral arch AR3 extends from the vicinity of the position (5) representing the first metatarsal head in FIG. 2 to the vicinity of the position (3) representing the fifth metatarsal head. The arches AR1 to AR3 can absorb the impact on the sole when walking.
In order to specify the foot arch, it is necessary to refer to the measurement results at positions other than the positions (2) and (6) (for example, the positions (1) and (3)).
Also, from the measurement results of position (6) and position (2) (and other measurement results of positions (1), (3), etc.), the center of gravity (the pressure center of the sole at the moment: the center of gravity of the center of gravity) The trajectory can be specified (determined).
 センサ6により計測される位置(6)に作用する力(圧力、せん断力)の計測結果と、センサ2により計測される位置(2)に作用する力(圧力、せん断力)の計測結果により、「扁平足」、「正常」、「ハイアーチ」の3種類を判定することが出来る。
 「扁平足」、「正常」、「ハイアーチ」の各々において、位置(6)で作用する力(圧力或いはせん断力)の計測結果と、位置(2)に作用する力(圧力或いはせん断力)の計測結果の大小関係が異なっている。すなわち、
 扁平足: 位置(2)に作用する力≒位置(6)に作用する力、或いは、
 位置(2)に作用する力≦位置(6)に作用する力
 正常: 位置(2)に作用する力>位置(6)に作用する力
 ハイアーチ: 位置(2)に作用する力、位置(6)に作用する力は共に検出されない。
 これについては、図8を参照して後述する。
From the measurement result of the force (pressure, shear force) acting on the position (6) measured by the sensor 6 and the measurement result of the force (pressure, shear force) acting on the position (2) measured by the sensor 2, Three types of “flat feet”, “normal”, and “high arch” can be determined.
Measurement results of force (pressure or shear force) acting at position (6) and force (pressure or shear force) acting at position (2) in each of “flat foot”, “normal”, and “high arch” The magnitude relationship of the results is different. That is,
Flat feet: force acting on position (2) ≒ force acting on position (6), or
Force acting on position (2) ≦ force acting on position (6) Normal: force acting on position (2)> force acting on position (6) High arch: force acting on position (2), position (6 The force acting on) is not detected.
This will be described later with reference to FIG.
 図2において、センサ7が配置される位置(図2で(7)で示す)は、第二中足骨頭(第二指(人差し指)の付け根部分)と第三中足骨頭(第三指(中指)の付け根部分)の間の領域に位置している。
 ここで、重心線は、踵と第二指をつないだ線(図2のラインLα)に沿って抜ける。そのため、第二指より第一指側(親指側)の領域にセンサ7を設けるのは不都合である。
 一方、第三指(中指)よりも小指側の領域は、重心線から外れてしまうので、センサ7を設けるのは不都合である。また、体重は足の中心線よりも内側に係るので、センサ7の位置(7)が足の中心線よりも外側にあると、体重が掛かった状態が検出できない。
In FIG. 2, the position where the sensor 7 is disposed (indicated by (7) in FIG. 2) is the second metatarsal head (the base portion of the second finger (index finger)) and the third metatarsal head (the third finger ( It is located in the area between the base part of the middle finger).
Here, the barycentric line passes along a line (line Lα in FIG. 2) connecting the heel and the second finger. For this reason, it is inconvenient to provide the sensor 7 in a region closer to the first finger (thumb side) than the second finger.
On the other hand, the region closer to the little finger than the third finger (middle finger) deviates from the barycentric line, so it is inconvenient to provide the sensor 7. Since the weight is on the inner side of the center line of the foot, if the position (7) of the sensor 7 is on the outer side of the center line of the foot, the weighted state cannot be detected.
 図示の実施形態によれば、上述した位置(1)~(7)に配置したセンサ1~7により、当該位置に作用する力を計測することにより、測定装置の所定位置に立っている状態の計測のみではなく、歩いている状態の計測が出来る。
 位置(1)~(7)に作用する力を計測し、解析装置20により解析することで分かる項目を、(前記アーチの種類の特定に加えて)以下に例示する。
 まず、足の柔軟性に個人差があることから、図3で示すアーチの柔軟性にも個人差が存在する。
 位置(2)、(6)、(7)の計測結果を解析することにより、アーチの柔軟性が分かる。アーチの柔軟性如何によっては、立って静止した状態では「ハイアーチ」でも、歩いているときには「扁平足」となる場合(アーチが柔らかい場合)がある。或いは、立って静止している状態では「正常」でも、歩いているときには「ハイアーチ」の場合(アーチが硬い場合)が存在する。
According to the illustrated embodiment, the sensors 1 to 7 arranged at the positions (1) to (7) described above are used to measure the force acting on the position, thereby standing in a predetermined position of the measuring device. Not only measurement but also walking measurement.
Items that can be understood by measuring the forces acting on the positions (1) to (7) and analyzing them by the analysis device 20 are exemplified below (in addition to specifying the type of the arch).
First, since there are individual differences in foot flexibility, there are also individual differences in the flexibility of the arch shown in FIG.
By analyzing the measurement results at the positions (2), (6), and (7), the flexibility of the arch can be understood. Depending on the flexibility of the arch, a “high arch” when standing still may result in a “flat foot” when walking (when the arch is soft). Alternatively, there is a case of “normal” when standing and stationary, but a “high arch” when walking (when the arch is hard).
 また、図7を参照して後述するが、位置(2)、(6)、(7)の計測結果を解析することにより、重心点(瞬間における足裏の圧力中心)とアーチ形状が適切に分かる。
 ここで、位置(2)、(6)、(7)に作用する力を計測しない場合、例えば位置(1)、(3)、(5)に作用する力のみを計測する場合には、そもそもアーチを特定することが不可能である。
 図示の実施形態では、位置(1)、(3)、(5)に作用する力に加えて、位置(2)、(6)、(7)に作用する力を計測することにより、アーチの特定を可能にしている。すなわち、位置(2)、(6)の計測結果により、縦アーチAR1、外アーチAR2が決定でき、縦アーチAR1から土踏まずの様子が把握出来る。さらに、位置(3)、(7)、(5)の計測結果により横アーチAR3の特定が可能になる。換言すれば、位置(7)の計測結果は、横アーチAR3の決定に不可欠である。
As will be described later with reference to FIG. 7, by analyzing the measurement results at positions (2), (6), and (7), the center of gravity (the pressure center of the sole at the moment) and the arch shape are appropriately I understand.
Here, when the force acting on the positions (2), (6), (7) is not measured, for example, when only the force acting on the positions (1), (3), (5) is measured, It is impossible to identify the arch.
In the illustrated embodiment, by measuring the forces acting on the positions (2), (6), (7) in addition to the forces acting on the positions (1), (3), (5), It enables identification. That is, the vertical arch AR1 and the outer arch AR2 can be determined from the measurement results of the positions (2) and (6), and the state of the arch can be grasped from the vertical arch AR1. Further, the lateral arch AR3 can be specified based on the measurement results at the positions (3), (7), and (5). In other words, the measurement result of the position (7) is indispensable for determining the lateral arch AR3.
 次に、重心線の特定に関して、従来は位置(1)、(3)、(5)のみに圧力センサを設置し、足においては位置(1)、(3)、(5)における荷重分布が比率として3:1:2になる、という前提で重心点を特定していた。
 しかし、図示の実施形態では、位置(2)、(6)、(7)にもセンサ(センサ2、6、7)を設置している。そして、位置(2)、(6)、(7)に作用する力(圧力、せん断力)も計測して重心点(COP)を正確に求め、さらにその軌跡である重心線を正確に特定している。この点についても、図7を参照して後述する。
Next, regarding the specification of the center of gravity line, conventionally, pressure sensors are installed only at the positions (1), (3), and (5), and the load distribution at the positions (1), (3), and (5) on the foot is The center of gravity point was specified on the assumption that the ratio was 3: 1: 2.
However, in the illustrated embodiment, sensors (sensors 2, 6, 7) are also installed at positions (2), (6), (7). The force (pressure, shear force) acting on the positions (2), (6), and (7) is also measured to accurately determine the center of gravity (COP), and the center of gravity line that is the locus is accurately specified. ing. This point will also be described later with reference to FIG.
 ここで、「足の骨軸」について説明する。
 「足の骨軸」は、踵骨***部を表す位置(1)と距骨とを貫く軸であり、位置(1)、(2)、(3)、(5)、(7)にせん断力センサ1、2、3、5、7を設け、計測結果を解析することにより、「足の骨軸」における動きを正確に把握することが出来る。これについても、図7を参照して後述する。
 位置(1)、(2)、(3)、(5)、(7)は足底部で大きく動く部位なので、この5箇所のせん断力を求めると、「足の骨軸」の動きを解析し易い。そして位置(1)、(2)、(3)、(5)、(7)のせん断力を解析して「足の骨軸」の動きを解析することで、歩行中の踵骨などのずれや移動の速度、力(荷重の変化)、向き、ねじれ等が評価出来る。
 また、足の骨軸の動きは、足裏の関節の柔軟性に依存する。
Here, the “foot bone axis” will be described.
The “foot bone axis” is an axis that penetrates the position (1) representing the rib bulge and the talus, and shear force is applied to the positions (1), (2), (3), (5), and (7). By providing the sensors 1, 2, 3, 5, and 7 and analyzing the measurement result, it is possible to accurately grasp the movement in the “foot bone axis”. This will also be described later with reference to FIG.
Positions (1), (2), (3), (5), and (7) are parts that move greatly at the bottom of the foot, so when the shear force of these five parts is obtained, the movement of the “bone axis of the foot” is analyzed. easy. By analyzing the shear force at positions (1), (2), (3), (5), and (7) and analyzing the motion of the “bone axis of the foot”, the displacement of the ribs and the like while walking Speed, force (change in load), direction, twist, etc. can be evaluated.
Further, the movement of the foot bone axis depends on the flexibility of the joint of the sole.
 位置(1)、(2)、(3)、(5)、(7)には、圧力センサではなく「せん断力センサ」を配置することが好適である。その理由について、図4を参照して説明する。
 位置(1)、(2)、(3)、(5)、(7)に作用する力を計測し、上述の解析を行うためには、図4(A)において、力の作用軸SH1の下端の矢印AHで示す力(紙面に垂直な方向の力も含む)を計測する必要がある。そのため、係る力の計測が可能なせん断力センサを、位置(1)、(2)、(3)、(5)、(7)に設置するのが好ましい。
 図4(B)で示す様に、圧力センサは垂直軸SH2の垂直方向荷重(符号P)しか計測することが出来ない。そのため、位置(1)、(2)、(3)、(5)、(7)に作用する力を計測するには不都合である。
It is preferable to arrange a “shear force sensor” in place of the pressure sensor at the positions (1), (2), (3), (5), and (7). The reason will be described with reference to FIG.
In order to measure the force acting on the positions (1), (2), (3), (5), and (7) and perform the above-described analysis, in FIG. 4 (A), the force acting axis SH1 It is necessary to measure the force indicated by the arrow AH at the lower end (including the force in the direction perpendicular to the paper surface). Therefore, it is preferable to install a shear force sensor capable of measuring such force at the positions (1), (2), (3), (5), and (7).
As shown in FIG. 4B, the pressure sensor can only measure the vertical load (reference symbol P) of the vertical axis SH2. Therefore, it is inconvenient to measure the force acting on the positions (1), (2), (3), (5), (7).
 上述した様に、位置(1)、(2)、(3)、(5)、(7)に作用するせん断力の計測結果を解析することにより、「足の骨軸」の動きが正確に把握することが出来る。例えば、足の骨軸から、踵の骨が外反しているか否かが判断出来る。
 例えば、アーチが硬く、足の骨軸が内側に動かない場合には、位置(2)、(3)側に荷重がかかり、歩行中に膝が捻じれ(回内モーメントが発生し)、将来、いわゆる「膝がこすれる」状態になって膝の痛みを訴える恐れがある。それに対して、図示の実施形態では位置(2)、(3)側に荷重がかかっているか否かを計測して、膝の痛みを訴える恐れがあるか否かを判定することが出来る。これについても、図9を参照して後述する。
As described above, by analyzing the measurement results of the shear force acting on the positions (1), (2), (3), (5), (7), the movement of the “foot bone axis” can be accurately performed. I can grasp it. For example, it can be determined from the bone axis of the foot whether or not the bone of the heel is valgus.
For example, when the arch is hard and the bone axis of the foot does not move inward, a load is applied to the positions (2) and (3), the knee is twisted during walking (pronation moment is generated), and in the future There is a risk of complaining of knee pain in a so-called “knee rub” condition. On the other hand, in the illustrated embodiment, it is possible to determine whether or not there is a risk of knee pain by measuring whether or not a load is applied to the positions (2) and (3). This will also be described later with reference to FIG.
 踵の上方の状態の一例を示す図5において、参考線L5L、L5Rは足Fの骨軸(実線で示す)と連続する脚部Lの中心軸(破線で示す)を表現している。参考線L5L、L5Rで示す様に、踵が曲がっている(外反している)場合には、踵が硬く(踵周辺の関節の可動域が制限されており)、外側(小指側)に曲がらないため、位置(1)におけるせん断力の数値が小さくなる。図5で示す様な場合(踵が硬く外側に曲がらない状態)では、膝にストレスが掛かり、痛みが発症する場合がある。
 その様な場合に、靴或いはインソールにおいて、靴の外側の高さ、内側の高さ或いは踵自体の高さを調節することにより、踵の動きを制限し、正常な重心線に近づけることが出来る。そのため、膝の痛みも低減する。これについては、図10を参照して後述する。
In FIG. 5 showing an example of the state above the heel, reference lines L5L and L5R represent the central axis (indicated by a broken line) of the leg L that is continuous with the bone axis of the foot F (indicated by a solid line). As shown by the reference lines L5L and L5R, when the heel is bent (extroverted), the heel is hard (the range of motion of the joint around the heel is limited) and bent outward (little finger side). Therefore, the value of the shear force at the position (1) is small. In the case as shown in FIG. 5 (a state where the heel is hard and does not bend outward), stress may be applied to the knee and pain may develop.
In such a case, in the shoe or insole, the movement of the heel can be restricted by adjusting the height of the outside of the shoe, the height of the inside of the shoe, or the height of the heel itself, and it can be brought close to the normal center of gravity line. . Therefore, knee pain is also reduced. This will be described later with reference to FIG.
 ここで位置(4)における圧力の値は、アーチ、脚の骨軸、重心線の特定とは関係が無い。
 位置(4)における圧力値が大きい場合には、歩行に際して足指が有効に使われており、地面を蹴り出す力が大きいことを意味している。すなわち、歩行に際して足指が有効に使われており、地面を蹴り出す力が大きければ、その他の条件が同じ場合には、歩幅が大きく、歩行速度が速く、クリアランス(歩行中のつま先と接地面との距離)も大きい。そのため、歩行が安定しており、歩行時の転倒の危険性が少ない。
 換言すれば、位置(4)の計測結果は、歩行機能を判定し、歩行時の転倒の可能性を判断するのに用いられる。
Here, the value of the pressure at the position (4) has no relation to the specification of the arch, the bone axis of the leg, and the center of gravity line.
When the pressure value at the position (4) is large, it means that the toes are used effectively during walking and the force to kick the ground is large. In other words, if the toes are used effectively during walking, and the force to kick the ground is large, if the other conditions are the same, the stride is large, the walking speed is high, and the clearance (toe and ground contact surface during walking) The distance to the is also large. Therefore, walking is stable and there is little risk of falls during walking.
In other words, the measurement result of the position (4) is used for determining the walking function and determining the possibility of falling during walking.
 図1で示す解析装置20とその作用について、図6~図10を参照して説明する。
 図示の実施形態で好適に用いられる解析装置20の機能ブロックを示す図6において、解析装置20(破線で囲まれた部分)は、重心点決定ブロック20A、重心点の軌跡である重心線を決定する重心線決定ブロック20B、アーチ決定ブロック20C、骨軸決定ブロック20D、判定ブロック20E、記憶ブロック20Fを有する。図6における符号20I、20Oは、それぞれ入力側インターフェース、出力側インターフェースを示している。
 図1を参照して述べた通り、解析装置20は、表示装置30、判定装置40と、情報信号ラインIL9、IL10により接続されている。
The analysis apparatus 20 shown in FIG. 1 and its operation will be described with reference to FIGS.
In FIG. 6 which shows the functional blocks of the analysis apparatus 20 preferably used in the illustrated embodiment, the analysis apparatus 20 (the part surrounded by a broken line) determines the center-of-gravity point determination block 20A and the center-of-gravity line which is the locus of the center-of-gravity point. A centroid line determination block 20B, an arch determination block 20C, a bone axis determination block 20D, a determination block 20E, and a storage block 20F. Reference numerals 20I and 20O in FIG. 6 indicate an input side interface and an output side interface, respectively.

 重心点決定ブロック20Aは、入力側インターフェース20I及び情報信号ラインIL1を介してセンサ1、2、3、5、6、7からの計測信号(位置(1)、(2)、(3)、(5)、(6)、(7)に作用する圧力或いはせん断力の計測結果)を受信し、重心点(COP)を求める機能を有している。
 重心点決定ブロック20Aで決定された重心点(瞬間における足裏の圧力中心)の情報は、情報信号ラインIL2を介して重心線決定ブロック20Bに送信される。
 重心点決定ブロック20Aにおいて重心点(COP)を決定する際には、従来公知のソフトウェア技術を用いて、測定対象者の特質等を考慮して、ケース・バイ・ケースで決定する。後述する重心線決定ブロック20B、アーチ決定ブロック20C、骨軸決定ブロック20Dにおいても同様である。
The center-of-gravity point determination block 20A includes measurement signals (positions (1), (2), (3), (7)) from the sensors 1, 2, 3, 5, 6, and 7 via the input-side interface 20I and the information signal line IL1. 5), (6), and (7) are received (measurement results of pressure or shear force) and have a function of obtaining the center of gravity (COP).
Information on the center of gravity point (the pressure center of the sole at the moment) determined by the center of gravity point determination block 20A is transmitted to the center of gravity line determination block 20B via the information signal line IL2.
When the center-of-gravity point determination block 20A determines the center-of-gravity point (COP), it is determined on a case-by-case basis using conventionally known software technology and taking into account the characteristics of the person being measured. The same applies to the center-of-gravity line determination block 20B, the arch determination block 20C, and the bone axis determination block 20D described later.
 重心線決定ブロック20Bは、情報信号ラインIL2を介して重心点決定ブロック20Aから重心点(COP)の情報を受信し、重心点の軌跡である重心線を決定する機能を有している。

Information on the centroid line determined by the centroid line determination block 20B is transmitted to the determination block 20E via the information signal line IL3.
 アーチ決定ブロック20Cは、入力側インターフェース20I及び情報信号ラインIL4を介して、センサ1、2、3、5、6、7からの計測信号(位置(1)、(2)、(3)、(5)、(6)、(7)に作用する圧力、せん断力の計測値)を受信し、それに基づいてアーチを決定する機能を有している。
 アーチ決定ブロック20Cでは、アーチを構成する縦アーチAR1、外アーチAR2、横アーチAR3のそれぞれの位置や形状を特定し、アーチが決定される。
 アーチ決定ブロック20Cで決定された縦アーチAR1、外アーチAR2、横アーチAR3の情報は、情報信号ラインIL5を介して判定ブロック20Eに送信される。
The arch determination block 20C receives measurement signals (positions (1), (2), (3), (7)) from the sensors 1, 2, 3, 5, 6, and 7 via the input-side interface 20I and the information signal line IL4. 5), (6), and (7) pressure and shear force measurement values) are received, and an arch is determined based thereon.
In the arch determination block 20C, the positions and shapes of the vertical arch AR1, the outer arch AR2, and the horizontal arch AR3 constituting the arch are specified, and the arch is determined.
Information on the vertical arch AR1, the outer arch AR2, and the horizontal arch AR3 determined by the arch determination block 20C is transmitted to the determination block 20E via the information signal line IL5.
 骨軸決定ブロック20Dは、入力側インターフェース20I及び情報信号ラインIL6を介してセンサ1、2、3、5、7からの計測信号(位置(1)、(2)、(3)、(5)、(7)に作用する圧力、せん断力の測定値)を受信し、足の骨軸の動きを把握して、足の骨軸を決定する機能を有している。
 骨軸決定ブロック20Dで決定された足の骨軸の情報は、情報信号ラインIL7を介して判定ブロック20Eに送信される。
The bone axis determination block 20D receives measurement signals (positions (1), (2), (3), (5)) from the sensors 1, 2, 3, 5, 7 via the input side interface 20I and the information signal line IL6. , (7) (measurement values of pressure and shear force), and the movement of the bone axis of the foot is grasped to determine the bone axis of the foot.
Information on the bone axis of the foot determined by the bone axis determination block 20D is transmitted to the determination block 20E via the information signal line IL7.

The flowchart in FIG. 9 determines whether or not there is such a fear. Therefore, the force acting on the positions (2) and (3) is measured, and if the measured force is large, a determination such as “the arch is hard and the knee may be twisted during walking” is performed. At the same time, a device for exercise and use for suppressing “twisting the knee while walking (pronation moment occurs)” is presented.

In step S22, it is determined whether a large load is applied to the positions (2) and (3) based on the forces acting on the positions (2) and (3) measured in step S21. Such determination is based on, for example, measurement results of forces acting on the positions (2) and (3), various data when the knee is twisted during walking (pronation moment is generated), and measurement data of the subject. This is performed by comparing with a comprehensively determined threshold value.
If it is determined in step S22 that a large load (to be dealt with) is applied to the positions (2) and (3) (step S22 is “Yes”), the process proceeds to step S23.

 ステップS24では、当該被験者には、現在或いは将来において、「歩行中に膝が捻じれる(回内モーメントが発生する)」と判断し、そのため、「将来、いわゆる「膝がこすれる」状態になって膝の痛みを訴える恐れがある」と判断する。
 そして、ステップS25に進む。
In step S23 (when it is determined that a large load (which should be dealt with) is applied to the positions (2) and (3)), “the arch is stiff and the bone axis of the foot does not move inward (therefore, the O leg It makes me feel and my legs bend outward). Then, the process proceeds to step S24.
In step S24, the subject is determined that the knee is twisted (pronunciation moment is generated during walking) at present or in the future, so that the subject is in a so-called “knee rub” state in the future. There is a risk of complaining of knee pain. "
Then, the process proceeds to step S25.
 ステップS25では、歩行中に膝が捻じれ(回内モーメントが発生し)、将来、いわゆる「膝がこすれる」状態になって膝の痛みを訴える恐れがある場合に対する改善策或いは対処法を提示する。

In the flowchart of FIG. 10, the shearing force acting on the position (1) is measured, and when the shearing force is small, it is determined that “the heel is bent (turned outward) and the heel does not bend outward”. Then, it presents gymnastics and appliances to suppress it.
 図10において、ステップS31では、センサ1により位置(1)に作用するせん断力を計測する。そしてステップS32に進む。
 ステップS32では、ステップS31で計測した位置(1)に作用するせん断力がしきい値N以下か否かを判断する。ここで、しきい値Nは、外反に関する蓄積されたデータと、被験者の計測データに基づいて、総合的に決定される。
 ステップS32で、位置(1)に作用するせん断力がしきい値N以下の場合は(ステップS32が「Yes」)、ステップS33に進む。
 一方、ステップS32で、位置(1)に作用するせん断力がしきい値Nより大きい場合は(ステップS32が「No」)、制御を終了する。
In FIG. 10, in step S31, the shear force acting on the position (1) is measured by the sensor 1. Then, the process proceeds to step S32.
In step S32, it is determined whether or not the shear force acting on the position (1) measured in step S31 is equal to or less than a threshold value N. Here, the threshold value N is comprehensively determined based on accumulated data relating to hallux valgus and measurement data of the subject.
If the shear force acting on the position (1) is equal to or less than the threshold value N in step S32 (step S32 is “Yes”), the process proceeds to step S33.
On the other hand, when the shearing force acting on the position (1) is larger than the threshold value N in step S32 (step S32 is “No”), the control is terminated.
 ステップS33(位置(1)に作用するせん断力がしきい値N以下の場合)は、被験者の「踵が曲がっており(外反している)、踵が硬くて外側(小指側)に曲がらない状態」と判断する。そしてステップS34に進む。
 ここで、踵が硬く外側に曲がらない状態では、膝にストレスが掛かり、痛みが発症する恐れがある。そのため、ステップS34では、踵が硬く外側に曲がらないため、膝にストレスが掛かり、痛みが発症する恐れがある場合の改善策或いは対処方法を提示する。
 ステップS34では、例えば、踵の外側に隙間のあるインソール或いは靴を提示する。靴或いはインソールにおいて、靴の外側の高さ、内側の高さ或いは踵自体の高さを調節することにより、踵の動きを制限し、正常な重心線に近づけることが出来る。そのため、膝の痛みも低減する。
Step S33 (when the shearing force acting on the position (1) is equal to or less than the threshold value N) is “the beard is bent (reversed), the beard is hard and does not bend outward (the little finger)”. It is judged as “state”. Then, the process proceeds to step S34.
Here, when the heel is hard and does not bend outward, stress may be applied to the knee and pain may develop. Therefore, in step S34, since the heel is hard and does not bend outward, an improvement measure or a coping method when the knee is stressed and there is a risk of developing pain is presented.
In step S34, for example, an insole or a shoe with a gap on the outside of the bag is presented. In the shoe or insole, by adjusting the height of the outside of the shoe, the height of the inside of the shoe, or the height of the heel itself, the movement of the heel can be limited and brought close to the normal center of gravity line. Therefore, knee pain is also reduced.
 また図示はしないが、図示の実施形態であれば、外反母趾についても、それを改善することが出来る。
 外反母趾或いはその傾向がある場合には、位置(7)に大きな荷重が掛かり、位置(3)で地面を強く蹴っている。そのため、位置(5)における地面を蹴る力を抑制し、位置(7)に係る荷重が適正になる様に靴やインソール等を工夫し、器具を提案し、或いは、位置(5)における地面を蹴る力を抑制し、位置(7)に係る荷重が適正になる様な運動プログラムを提案することが出来る。
Although not illustrated, the embodiment of the illustrated embodiment can improve the hallux valgus.
When the hallux valgus or the tendency exists, a large load is applied to the position (7), and the ground is strongly kicked at the position (3). Therefore, the force of kicking the ground at the position (5) is suppressed, the shoes and the insole are devised so that the load related to the position (7) is appropriate, the device is proposed, or the ground at the position (5) is It is possible to propose an exercise program that suppresses the kicking force and makes the load related to the position (7) appropriate.
 図示の実施形態に係る足裏計測装置100によれば、インソール10(或いは靴)の足裏と接触する部材にセンサ1~7を設けることにより検出部を構成しているので、装置全体を小型化することが出来る。
 そのため、大型装置の様に被測定者に余計なストレスを与えてしまうことはなく、正確な計測が可能である。また、小型化された装置であるので、足裏計測装置100を着用或いは装着した状態で運動することが出来る。そのため、運動している中で(例えば歩行中に)、位置(1)~(7)(センサ1~7を配置)に作用する力(せん断力或いは圧力)を直接計測することが可能である。そのため、従来技術の様に、静止した状態の足裏圧力から歩行中の足裏圧力を推定する必要はない。
 特に、図示の実施形態では、センサ1~7の出力を解析装置20に対して無線で送信しているので、有線で計測結果を送信する場合に比較して、被験者が運動中(例えば歩行中)における計測結果の送信が容易である。
According to the sole measuring apparatus 100 according to the illustrated embodiment, the detection unit is configured by providing the sensors 1 to 7 on the member that comes into contact with the sole of the insole 10 (or shoes). Can be
Therefore, the measurement subject is not subjected to excessive stress unlike a large-sized device, and accurate measurement is possible. Moreover, since it is a miniaturized device, it is possible to exercise with the sole measuring device 100 worn or worn. Therefore, it is possible to directly measure the force (shearing force or pressure) acting on the positions (1) to (7) (sensors 1 to 7 are arranged) while exercising (eg during walking). . Therefore, unlike the prior art, there is no need to estimate the sole pressure during walking from the sole pressure in a stationary state.
In particular, in the illustrated embodiment, the outputs of the sensors 1 to 7 are wirelessly transmitted to the analysis device 20, so that the subject is exercising (for example, walking) compared to the case where the measurement result is transmitted by wire. ) Is easy to transmit the measurement results.
 また図示の実施形態では、踵骨***部(位置1)、立方骨(位置2)、第五中足骨頭(位置3)、第一中足骨頭(位置5)、中間楔状骨(位置6)、横足弓中心(位置7)と対応する位置にセンサを設けているので、各センサの計測値から足の重心点、アーチ(縦アーチAR1、外アーチAR2、横アーチAR3)、足の骨軸を決定することが出来る。
 そして、足の重心点の軌跡である「足の重心線」も容易に求めることが出来る。
 足の重心線、アーチ(横アーチ、縦アーチ、外アーチ)、足の骨軸を決定することにより、変形性膝関節症や外反拇指以外の異常の有無を判断して、当該異常を矯正或いは抑制する様な器具、運動を提案することが可能である。
 そして、変形性膝関節症や外反拇指以外の各種異常を判断するパラメータとして、足の重心線、アーチ、足の骨軸という足圧分布以外のパラメータを用いることが出来る。
In the illustrated embodiment, the rib ridge (position 1), the cubic bone (position 2), the fifth metatarsal head (position 3), the first metatarsal head (position 5), and the intermediate wedge bone (position 6). Since the sensor is provided at a position corresponding to the center of the lateral foot arch (position 7), the center of gravity of the foot, the arch (the vertical arch AR1, the outer arch AR2, the lateral arch AR3), and the bone of the foot from the measured values of each sensor Axis can be determined.
Then, the “foot barycentric line” that is the trajectory of the barycentric point can be easily obtained.
By determining the barycentric line, arch (lateral arch, vertical arch, external arch), and bone axis of the foot, it is possible to determine whether there is an abnormality other than knee osteoarthritis or a hallux phalanx and correct the abnormality. Alternatively, it is possible to propose a device or exercise that can be suppressed.
As parameters for determining various abnormalities other than knee osteoarthritis and hallux phalanges, parameters other than foot pressure distribution such as foot center of gravity, arch, and foot bone axis can be used.
 ここで、拇指接地面(位置4)における圧力値が大きい場合には、歩行に際して足指が有効に使われており、地面を蹴り出す力が大きいことを意味している。従って、その他の条件が同じであれば、拇指接地面(位置4)における圧力値が大きい場合には、歩幅が大きく、歩行速度が速く、クリアランス(歩行中のつま先と接地面との距離)も大きいことになる。そのため、歩行が安定しており、歩行時の転倒の危険性が少ない。
 図示の実施形態においては、拇指接地面(位置4)にセンサ4を設けているので、当該センサ4(位置4)の計測結果から、歩行機能が判定され、歩行時に転倒する可能性を判断することが出来る。
Here, when the pressure value on the thumb contact surface (position 4) is large, it means that the toes are used effectively during walking and the force to kick the ground is large. Therefore, if other conditions are the same, when the pressure value on the thumb contact surface (position 4) is large, the stride is large, the walking speed is fast, and the clearance (the distance between the toe and the contact surface during walking) is also large. It will be big. Therefore, walking is stable and there is little risk of falls during walking.
In the illustrated embodiment, since the sensor 4 is provided on the thumb contact surface (position 4), the walking function is determined from the measurement result of the sensor 4 (position 4), and the possibility of falling down during walking is determined. I can do it.
 そして図示の実施形態では、位置(6)と位置(2)に作用する力の計測値から、被験者が「扁平足」、「正常」、「ハイアーチ」の何れに該当するのかを特定出来る。
 さらに、位置(2)、(3)側に作用する力の計測値から、「アーチが硬く歩行中に膝が捻じれる」か否かを判断することが出来て、それ抑制する運動、使用器具も併せて提示することが出来る。
 それに加えて、位置(1)に作用するせん断力の計測値から、「踵が曲がっていて(外反していて)、踵が外側に曲がらない状態」であるか否かを判断することが出来て、それ抑制する使用器具を提示することが出来る(図10)。
In the illustrated embodiment, it is possible to specify whether the subject corresponds to “flat foot”, “normal”, or “high arch” from the measurement value of the force acting on the position (6) and the position (2).
Furthermore, from the measured values of the force acting on the positions (2) and (3), it is possible to determine whether or not “the knee is twisted while walking because the arch is stiff”, and the exercise and equipment used Can also be presented.
In addition, from the measured value of the shear force acting on the position (1), it is possible to determine whether or not “the heel is bent (valgus) and the heel does not bend outward”. Thus, it is possible to present an appliance to be used to suppress it (FIG. 10).
 図示の実施形態はあくまでも例示であり、本発明の技術的範囲を限定する趣旨の記述ではないことを付記する。
 例えば、図5では外反の場合を示しているが、本発明では内反に対しても対応することが出来る。
It should be noted that the illustrated embodiment is merely an example, and is not a description to limit the technical scope of the present invention.
