Description

本発明は、身体の重心動揺パラメータから筋力，関節柔軟性，平衡感覚等の身体の運動能力に関係する健康指標を測定する健康測定装置に関する。 The present invention relates to a health measurement device that measures health indices related to the body's motor ability, such as muscle strength, joint flexibility, and balance sensation, from body sway parameters.

従来より、身体の重心位置の軌跡長や重心位置の軌跡により囲まれる面積等の身体の重心動揺パラメータを測定することにより、身体の運動能力に関係する健康指標を測定する装置が知られている。具体的には、現在の身体の重心位置と目標となる身体の重心位置を表示し、身体の重心位置が現在の重心位置から目標となる重心位置に移動するまでの時間を測定することにより健康指標を測定する装置や、重量計の踏台に掛かる荷重変動から健康指標を測定する装置が考案されている（特許文献１，２参照）。

Description of the Related Art Conventionally, a device that measures a health index related to a body's athletic ability by measuring a body's center-of-gravity sway parameter such as the length of the body's center-of-gravity position or the area surrounded by the locus of the center of gravity position is known. . Specifically, it displays the current body centroid position and the target body centroid position, and measures the time it takes for the body centroid position to move from the current centroid position to the target centroid position. An apparatus for measuring an index and an apparatus for measuring a health index from load fluctuations applied to a platform of a weight scale have been devised (see Patent Documents 1 and 2).

重心動揺パラメータを測定する際には、被験者は閉眼片足立ち姿勢や最大前傾姿勢，最大後傾姿勢等の測定姿勢を所定時間保持する必要があるが、このような測定姿勢を所定時間保持することは高齢者等にとって非常に難しく、安全性の面で問題がある。さらに、最大前傾姿勢や最大後傾姿勢等の測定姿勢は被験者の主観によって異なり、測定姿勢の基準が不明確であるために、測定の度毎に測定姿勢が変化することによって健康指標を再現性よく測定することが難しい。このため、従来の装置は、主に医療機関において使用されており、一般家庭向けには普及していないというのが現状である。 When measuring the center-of-gravity sway parameter, the subject needs to hold a measurement posture such as a single-leg standing posture, a maximum forward tilt posture, or a maximum backward tilt posture for a predetermined time. This is very difficult for elderly people and the like, and there is a problem in terms of safety. In addition, measurement postures such as the maximum forward leaning posture and maximum backward leaning posture vary depending on the subject's subjectivity, and because the measurement posture reference is unclear, the health index is reproduced by changing the measurement posture at each measurement. It is difficult to measure well. For this reason, the conventional apparatus is mainly used in medical institutions and is not widely used for general households.

本発明は、上記課題を解決するためになされたものであり、その目的は、身体の運動能力に関係する健康指標を一般家庭でも簡便に再現性よく測定可能な健康測定装置を提供することにある。 The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a health measuring device that can easily and easily measure a health index related to physical exercise ability even in a general home. is there.

本発明に係る健康測定装置は、被験者の足が乗せられる踏台と、踏台に埋設され、被検者の足裏の一部と接触可能な少なくとも１つのブロック部と、ブロック部を上下方向に昇降させることにより、被検者の足裏の少なくとも１箇所を直接押圧して、被験者の立位姿勢を変化させる姿勢調整部と、踏台に足を乗せた状態の被験者の重心位置を検出する検出部と、検出部により検出された重心位置から重心動揺パラメータを算出し、算出された重心動揺パラメータに基づき被験者の運動能力に関係する健康指標を算出する演算部とを備える。 The health measurement device according to the present invention includes a step on which a subject's foot is placed, at least one block portion that is embedded in the step and can be in contact with a part of a subject's foot, and the block portion is moved up and down. A posture adjusting unit that directly presses at least one place on the sole of the subject to change the standing posture of the subject, and a detection unit that detects the position of the center of gravity of the subject with the foot on the step And a calculation unit that calculates a center-of-gravity fluctuation parameter from the position of the center of gravity detected by the detection unit, and calculates a health index related to the exercise ability of the subject based on the calculated center-of-gravity fluctuation parameter.

本発明に係る健康測定装置によれば、踏台に埋設されたブロックを昇降させることにより重心動揺パラメータを算出するために必要な測定姿勢に被験者の姿勢を誘導するので、被験者の運動能力に関係する健康指標を一般家庭でも簡便に再現性よく測定することができる。 According to the health measurement device of the present invention, the posture of the subject is guided to the measurement posture necessary to calculate the center-of-gravity sway parameter by raising and lowering the block embedded in the platform, and therefore, related to the exercise ability of the subject. Health indicators can be measured easily and with good reproducibility even in general households.

以下、本発明の実施形態となる健康測定装置の構成について説明する。 Hereinafter, the structure of the health measuring apparatus which becomes embodiment of this invention is demonstrated.

〔第１の実施形態〕
始めに、図１乃至図４を参照して、本発明の第１の実施形態となる健康測定装置の構成について説明する。 [First Embodiment]
First, with reference to FIG. 1 thru | or FIG. 4, the structure of the health measuring apparatus used as the 1st Embodiment of this invention is demonstrated.

〔装置の構成〕
本発明の第１の実施形態となる健康測定装置は、図４に示すように、被験者の両足が乗せられる踏台２、踏台２内部に埋設されたロードセル（荷重センサ）３ａ，３ｂ，３ｃ，３ｄと、ロードセル３ａ，３ｂ，３ｃ，３ｄの出力信号を増幅出力する増幅器４ａ，４ｂ，４ｃ，４ｄと、増幅器４ａ，４ｂ，４ｃ，４ｄの出力信号をＡＤ（アナログ／デジタル）変換するＡＤ変換器５と、ＡＤ変換器５の出力信号を用いて重心動揺パラメータ及び被験者の運動能力に関係する健康指標を演算する演算部６と、被験者の重心位置や演算部６により演算された重心動揺パラメータ及び被験者の運動能力に関係する健康指標を表示する表示部７とを主な構成要素として備える。 [Device configuration]

And amplifiers 4a, 4b, 4c and 4d for amplifying and outputting the output signals of the load cells 3a, 3b, 3c and 3d, and an AD converter for AD (analog / digital) conversion of the output signals of the amplifiers 4a, 4b, 4c and 4d 5, a calculation unit 6 that calculates a centroid swing parameter and a health index related to the exercise ability of the subject using the output signal of the AD converter 5, a centroid swing parameter calculated by the centroid position of the subject and the calculation unit 6, and The display part 7 which displays the health parameter | index relevant to a test subject's athletic ability is provided as a main component.

健康測定装置の本体１には、図１に示すように、表示部７と、踏台２の所定位置に設けられたブロック８ａ，８ｂと、切替スイッチ９と、電源スイッチ１１と、足固定位置ガイド１２ａ，１２ｂとが設けられている。ブロック８ａ，８ｂは、ゴム弾性体等により形成され、図２に示すように、被験者による切替スイッチ９の押下操作と連動してアクチュエータ（図示せず）により上下方向に昇降制御される。具体的には、ブロック８ａ，８ｂの上面は、通常時は踏台２の面とほぼ同一面になるように埋設されているが、アクチュエータが、ポンプ２９により油圧を発生させ、シリンダー３０内でプランジャー３１を押し出すことにより、図３に示すように所定量隆起する。 As shown in FIG. 1, the body 1 of the health measuring device includes a display unit 7, blocks 8 a and 8 b provided at predetermined positions on the platform 2, a changeover switch 9, a power switch 11, and a foot fixing position guide. 12a and 12b are provided. The blocks 8a and 8b are formed of a rubber elastic body or the like, and as shown in FIG. 2, the elevation is controlled up and down by an actuator (not shown) in conjunction with the pressing operation of the changeover switch 9 by the subject. Specifically, the upper surfaces of the blocks 8 a and 8 b are normally embedded so as to be substantially flush with the surface of the platform 2, but the actuator generates hydraulic pressure by the pump 29, and the plan is generated in the cylinder 30. By pushing out the jar 31, it is raised by a predetermined amount as shown in FIG.

〔健康指標測定時の動作〕
このような構成を有する健康測定装置は、以下のように動作することにより被験者の運動能力に関係する健康指標を測定する。すなわち、始めに被験者が、電源スイッチ１１をオン状態に切り替えた後、踏台２に乗り、図２に示すように足固定位置ガイド１２ａ，１２ｂに足１３を合わせて静止立位状態を保持する。次に、増幅器４ａ，４ｂ，４ｃ，４ｄがロードセル３ａ，３ｂ，３ｃ，３ｄの検出信号を増幅し、ＡＤ変換器５が所定のサンプリング周波数で増幅器４ａ，４ｂ，４ｃ，４ｄの出力信号をＡＤ変換する。次に、演算部６が、ＡＤ変換器５の出力信号を重心位置座標に変換し、変換された重心位置座標を用いて軌跡長，矩形面積，平均重心位置等の重心動揺パラメータを算出する。なお、重心動揺パラメータの算出方法は本願発明の出願時点で公知であるのでその説明は省略する。詳しくは、特公昭４８−３３９５０号公報，昭５０−１６９１８号公報，昭６０−１６９１９号公報，特許２７６０４７１号公報，特許２７１０２２３号公報，特許２７６０４７２号公報を参照のこと。 [Operation during health index measurement]
The health measuring device having such a configuration measures a health index related to the exercise ability of the subject by operating as follows. That is, first, after the subject switches the power switch 11 to the ON state, the subject gets on the platform 2 and puts the foot 13 on the foot fixing position guides 12a and 12b as shown in FIG. Next, the amplifiers 4a, 4b, 4c, 4d amplify the detection signals of the load cells 3a, 3b, 3c, 3d, and the AD converter 5 converts the output signals of the amplifiers 4a, 4b, 4c, 4d to AD at a predetermined sampling frequency. Convert. Next, the calculation unit 6 converts the output signal of the AD converter 5 into the center-of-gravity position coordinates, and uses the converted center-of-gravity position coordinates to calculate center-of-gravity fluctuation parameters such as a trajectory length, a rectangular area, and an average center-of-gravity position. The method for calculating the center-of-gravity sway parameter is well known at the time of filing of the present invention and will not be described. For details, see Japanese Patent Publication Nos. 48-33950, 50-16918, 60-16919, 2760471, 2710223, and 2760472.

次に、被験者が切替スイッチ９を押下するのに応じてアクチュエータが作動することによって、ブロック８ａ，８ｂが踏台２の水平面から所定量隆起する。そして被験者は再び、足固定位置ガイド１２ａ，１２ｂに足１３を合わせ、図３に示すように足裏の一部、例えば土踏まず１４が持ち上げられた状態で静止立位状態を保持する。土踏まず１４が持ち上げられたことにより、足１３と踏台２との接地面積が減少し、ブロック８ａ，８ｂが隆起していない状態に比べて被験者の身体のバランスは悪くなる。従ってバランスを保持するためには足裏の筋力と足関節の柔軟性が必要になる。そしてこの状態で再び所定時間重心動揺を計測し、軌跡長，矩形面積，平均重心位置等の重心動揺パラメータが算出される。 Next, the actuator is actuated in response to the subject pressing the changeover switch 9, whereby the blocks 8 a and 8 b are raised by a predetermined amount from the horizontal surface of the platform 2. Then, the subject again puts the foot 13 on the foot fixing position guides 12a and 12b, and maintains a stationary standing state in a state where a part of the sole, for example, the arch 14 is lifted as shown in FIG. When the arch 14 is lifted, the ground contact area between the foot 13 and the platform 2 is reduced, and the balance of the subject's body is worse than when the blocks 8a and 8b are not raised. Therefore, in order to maintain the balance, the muscle strength of the sole and the flexibility of the ankle joint are required. In this state, the center-of-gravity fluctuation is measured again for a predetermined time, and the center-of-gravity fluctuation parameters such as the locus length, the rectangular area, and the average center-of-gravity position are calculated.

このように本発明の第１の実施形態となる健康測定装置では、ブロック８ａ，８ｂが隆起することにより２種類の測定姿勢における重心動揺パラメータを算出するので、これらのパラメータを用いて筋力，関節柔軟性，平衡感覚機能等の被験者の運動能力に関係する健康指標を測定することができる。一般に、筋力，関節柔軟性，平衡感覚機能が優れている場合、同姿勢における重心動揺パラメータの差は小さい。一方、筋力，柔軟性，平衡感覚機能が劣っている場合には、両姿勢の重心動揺パラメータの差は大きく現れる。また、運動等トレーニングにより筋力，柔軟性，平衡感覚機能が向上すれば両姿勢の重心動揺パラメータの差は小さくなるためトレーニング効果を簡易的、且つ、安全に計測することができる。 As described above, in the health measurement apparatus according to the first embodiment of the present invention, the blocks 8a and 8b are raised to calculate the center-of-gravity sway parameters in the two types of measurement postures. It is possible to measure health indicators related to the motor ability of subjects such as flexibility and balance sensory function. In general, when the muscle strength, joint flexibility, and balance sensory function are excellent, the difference in the center-of-gravity sway parameter in the same posture is small. On the other hand, when the muscle strength, flexibility, and balance sensory function are inferior, the difference in the center-of-gravity sway parameter between both postures appears greatly. Further, if muscle strength, flexibility, and balance sensory function are improved by training such as exercise, the difference in the center-of-gravity sway parameter between the two postures is reduced, so that the training effect can be measured easily and safely.

〔第２の実施形態〕
次に、図５，図６を参照して、本発明の第２の実施形態となる健康測定装置の構成について説明する。 [Second Embodiment]
Next, with reference to FIG. 5 and FIG. 6, the configuration of a health measuring apparatus according to the second embodiment of the present invention will be described.

本発明の第２の実施形態となる健康測定装置では、図５，図６に示すように、ロック機構１６ａ，１６ｂによって踏台２に傾斜板１５ａ，１５ｂが水平に保持されている。傾斜板１５ａ，１５ｂの上面は、通常時は踏台２の面とほぼ同一面になるように埋設されているが、アクチュエータが、ポンプ２９により油圧を発生させ、シリンダー３０内でプランジャー３１ａ，３１ｂを持ち上げることにより、所定量隆起する。また、ポンプ２９とシリンダー３０間には電磁弁３２ａ，３２ｂが設けられ、ポンプ２９が発生する油圧の切り替えを行うことができる。 In the health measuring apparatus according to the second embodiment of the present invention, as shown in FIGS. 5 and 6, the inclined plates 15a and 15b are held horizontally on the platform 2 by the lock mechanisms 16a and 16b. The upper surfaces of the inclined plates 15a and 15b are normally embedded so as to be substantially flush with the surface of the platform 2, but the actuator generates hydraulic pressure by the pump 29 and the plungers 31a and 31b in the cylinder 30. Raise a predetermined amount. In addition, electromagnetic valves 32a and 32b are provided between the pump 29 and the cylinder 30, and the hydraulic pressure generated by the pump 29 can be switched.

〔健康指標測定時の動作〕
このような構成を有する健康測定装置は、以下のように動作することにより被験者の運動能力に関係する健康指標を測定する。すなわち、始めに被験者が、電源スイッチ１１をオン状態に切り替え、図６（ａ）に示すように踏台２に乗り、足固定位置ガイド１２ａ，１２ｂに足を合わせ、静止立位状態を保持する。次に、増幅器４ａ，４ｂ，４ｃ，４ｄがロードセル３ａ，３ｂ，３ｃ，３ｄの検出信号を増幅し、ＡＤ変換器５が所定のサンプリング周波数で増幅器４ａ，４ｂ，４ｃ，４ｄの出力信号をＡＤ変換する。次に、演算部６が、ＡＤ変換器５の出力信号を重心位置座標に変換し、変換された重心位置座標を用いて軌跡長，矩形面積，平均重心位置等の重心動揺パラメータを算出する。 [Operation during health index measurement]
The health measuring device having such a configuration measures a health index related to the exercise ability of the subject by operating as follows. That is, first, the subject switches the power switch 11 to the on state, gets on the platform 2 as shown in FIG. 6 (a), puts his / her feet on the foot fixing position guides 12a and 12b, and maintains the stationary standing state. Next, the amplifiers 4a, 4b, 4c, 4d amplify the detection signals of the load cells 3a, 3b, 3c, 3d, and the AD converter 5 converts the output signals of the amplifiers 4a, 4b, 4c, 4d to AD at a predetermined sampling frequency. Convert. Next, the calculation unit 6 converts the output signal of the AD converter 5 into the center-of-gravity position coordinates, and uses the converted center-of-gravity position coordinates to calculate center-of-gravity fluctuation parameters such as a trajectory length, a rectangular area, and an average center-of-gravity position.

次に被験者が切替スイッチ９を押下するのに応じて、傾斜板１５ｂの一方のロック機構１６ａが解除されると共に電磁弁３２ａ及び電磁弁３２ｂがそれぞれ開状態及び閉状態になる。次に、アクチュエータによってプランジャー３１ａが持ち上がり、ブロック１９ａが隆起することにより、図６（ｂ）に示すように傾斜板１５ｂが傾き、踵部１７が持ち上がる。そしてこの状態で所定時間重心動揺を計測し、軌跡長，矩形面積，平均重心位置等の重心動揺パラメータが算出される。その後、ポンプ２９が油圧を下げることにより傾斜板１５ｂを水平状態に戻し、ロック機構１６ａが作動し傾斜板１５ｂは再び水平に保持される。 Next, in response to the subject pressing down the changeover switch 9, one of the locking mechanisms 16a of the inclined plate 15b is released and the electromagnetic valve 32a and the electromagnetic valve 32b are opened and closed, respectively. Next, the plunger 31a is lifted by the actuator, and the block 19a is raised, whereby the inclined plate 15b is tilted and the flange portion 17 is lifted as shown in FIG. 6 (b). In this state, the center-of-gravity fluctuation is measured for a predetermined time, and the center-of-gravity fluctuation parameters such as the locus length, the rectangular area, and the average center-of-gravity position are calculated. Thereafter, the pump 29 lowers the hydraulic pressure to return the inclined plate 15b to the horizontal state, the lock mechanism 16a is activated, and the inclined plate 15b is held horizontally again.

次に、被験者が再度切替スイッチ９を押下するのに応じて今度はロック機構１６ｂが解除されると共に、電磁弁３２ａ及び電磁弁３２ｂがそれぞれ閉状態及び開状態になる。次に、アクチュエータによって図６（ｃ）に示すようにブロック１９ｂが隆起し、拇指丘部１８が持ち上がり、所定の角度で身体を傾斜するように誘導させる。そしてこの状態で所定時間重心動揺を計測し、軌跡長，矩形面積，平均重心位置等の重心動揺パラメータが算出される。その後、ポンプ２９が油圧を下げることで傾斜板１５ｂが水平状態まで戻され、ロック機構１６ｂが作動し傾斜板１５ｂは水平に保たれる。 Next, when the subject presses the changeover switch 9 again, the lock mechanism 16b is released and the electromagnetic valve 32a and the electromagnetic valve 32b are closed and opened, respectively. Next, as shown in FIG. 6 (c), the block 19b is raised by the actuator, and the mound hill part 18 is lifted and guided to tilt the body at a predetermined angle. In this state, the center-of-gravity fluctuation is measured for a predetermined time, and the center-of-gravity fluctuation parameters such as the locus length, the rectangular area, and the average center-of-gravity position are calculated. Thereafter, when the pump 29 lowers the hydraulic pressure, the inclined plate 15b is returned to the horizontal state, the lock mechanism 16b is activated, and the inclined plate 15b is kept horizontal.

このように本発明の第２の実施形態となる健康測定装置ではブロック１９ａ，１９ｂが隆起することによって傾斜板１５ａ，１５ｂが傾くことにより３種類の測定姿勢における重心動揺パラメータを算出するので、これらのパラメータを用いて筋力，柔軟性，平衡感覚機能等の被験者の運動能力に関係する健康指標を測定することができる。一般に、被験者の足裏が持ち上がると水平面に立っている状態に比べて被験者の姿勢のバランスが悪くなる。そのため筋力，柔軟性，平衡感覚機能が優れている場合、３種類の測定姿勢におけるパラメータ間の差は小さい。一方、筋力，柔軟性，平衡感覚機能が劣っている場合にはパラメータ間の差は大きく現れる。また、運動等トレーニングにより筋力，柔軟性，平衡感覚機能が向上すればパラメータ間の差は小さくなるため、トレーニング効果を簡易的かつ安全に計測することができる。 As described above, in the health measuring apparatus according to the second embodiment of the present invention, the gravity center fluctuation parameters in the three types of measurement postures are calculated by tilting the inclined plates 15a and 15b as the blocks 19a and 19b are raised. Can be used to measure health indicators related to the subject's motor skills, such as muscle strength, flexibility, and balance sensory function. In general, when the subject's sole is lifted, the balance of the posture of the subject becomes worse as compared to the state of standing on the horizontal plane. Therefore, when the muscle strength, flexibility, and balance sensory function are excellent, the difference between the parameters in the three types of measurement postures is small. On the other hand, when the muscle strength, flexibility, and balance sensory function are inferior, the difference between the parameters appears greatly. In addition, if the muscle strength, flexibility, and balance sensory function are improved by training such as exercise, the difference between the parameters is reduced, so that the training effect can be measured easily and safely.

〔第３の実施形態〕
次に、図７，図８を参照して、本発明の第３の実施形態となる健康測定装置の構成について説明する。 [Third Embodiment]
Next, with reference to FIG. 7 and FIG. 8, the structure of the health measuring apparatus which becomes the 3rd Embodiment of this invention is demonstrated.

本発明の第３の実施形態となる健康測定装置では、図７，図８に示すように、踏台２に踵部１７及び拇指丘部１８にほぼ当接するようにブロック１９ａ〜１９ｄが設けられている。ブロック１９ａ〜１９ｄの上面は、通常時は踏台２の面とほぼ同一面になるように埋設されているが、アクチュエータが、ポンプ２９により油圧を発生させ、又は油圧を下げ、シリンダー３０内でプランジャー３１ａ，ｂを上下させることにより、上下方向に所定量移動する。 In the health measuring apparatus according to the third embodiment of the present invention, as shown in FIGS. 7 and 8, blocks 19 a to 19 d are provided on the platform 2 so as to substantially come into contact with the heel part 17 and the thumb hill part 18. Yes. The upper surfaces of the blocks 19a to 19d are normally embedded so as to be substantially flush with the surface of the platform 2, but the actuator generates hydraulic pressure by the pump 29 or lowers the hydraulic pressure so that the plan is generated in the cylinder 30. The jars 31a and 31b are moved up and down to move a predetermined amount.

〔健康指標測定時の動作〕
このような構成を有する健康測定装置は、以下のように動作することにより被験者の運動能力に関係する健康指標を測定する。すなわち、始めに被験者が、電源スイッチ１１をオン状態に切り替え、図８（ａ）に示すように踏台２に乗り、足固定位置ガイド１２ａ，１２ｂに足を合わせ、静止立位姿勢を保持する。次に、増幅器４ａ，４ｂ，４ｃ，４ｄがロードセル３ａ，３ｂ，３ｃ，３ｄの検出信号を増幅し、ＡＤ変換器５が所定のサンプリング周波数で増幅器４ａ，４ｂ，４ｃ，４ｄの出力信号をＡＤ変換する。次に、演算部６が、ＡＤ変換器５の出力信号を重心位置座標に変換し、変換された重心位置座標を用いて軌跡長，矩形面積，平均重心位置等の重心動揺パラメータを算出する。 [Operation during health index measurement]
The health measuring device having such a configuration measures a health index related to the exercise ability of the subject by operating as follows. That is, first, the subject switches the power switch 11 to the on state, gets on the platform 2 as shown in FIG. 8A, puts his / her feet on the foot fixing position guides 12a and 12b, and maintains a stationary standing posture. Next, the amplifiers 4a, 4b, 4c, 4d amplify the detection signals of the load cells 3a, 3b, 3c, 3d, and the AD converter 5 converts the output signals of the amplifiers 4a, 4b, 4c, 4d to AD at a predetermined sampling frequency. Convert. Next, the calculation unit 6 converts the output signal of the AD converter 5 into the center-of-gravity position coordinates, and uses the converted center-of-gravity position coordinates to calculate center-of-gravity fluctuation parameters such as a trajectory length, a rectangular area, and an average center-of-gravity position.

次に被験者が切替スイッチ９を再び押下するのに応じて、電磁弁３２ａ及び電磁弁３２ｂがそれぞれ開状態及び閉状態になる。次に、アクチュエータが作動することにより、図８（ｂ）に示すようにブロック１９ａが踏台２の水平面から所定量隆起し、踵部１７が持ち上げられることで被験者の姿勢はやや前傾姿勢に誘導される。この状態で所定時間重心動揺を計測し、軌跡長，矩形面積，平均重心位置等の重心動揺パラメータが算出される。 Next, when the subject presses the changeover switch 9 again, the electromagnetic valve 32a and the electromagnetic valve 32b are opened and closed, respectively. Next, when the actuator is actuated, the block 19a is raised by a predetermined amount from the horizontal surface of the platform 2 as shown in FIG. 8 (b), and the posture of the subject is guided to a slightly forward tilted posture by lifting the buttocks 17. Is done. In this state, the center-of-gravity fluctuation is measured for a predetermined time, and the center-of-gravity fluctuation parameters such as the locus length, the rectangular area, and the average center-of-gravity position are calculated.

次に被験者が切替スイッチ９を再び押下するのに応じて、ブロック１９ａが踏台２の水平面の位置まで戻った後、電磁弁３２ａ及び電磁弁３２ｂがそれぞれ閉状態及び開状態になる。次に、アクチュエータが作動することにより油圧が発生し、図８（ｃ）に示すようにブロック１９ｂが踏台２の水平面から所定量隆起することにより足裏の拇指丘部１８が持ち上げられる。このとき被験者の身体は拇指丘部１８が持ち上げられることでやや後傾姿勢に誘導される。この状態で所定時間重心動揺を計測し、軌跡長，矩形面積，平均重心位置等の重心動揺パラメータが算出される。その後、ブロック１９ｂは踏台２の水平面の位置まで戻る。 Next, in response to the subject pressing down the changeover switch 9 again, after the block 19a returns to the position on the horizontal surface of the platform 2, the electromagnetic valve 32a and the electromagnetic valve 32b are in a closed state and an open state, respectively. Next, when the actuator is operated, hydraulic pressure is generated, and as shown in FIG. 8C, the block 19b is raised from the horizontal surface of the platform 2 by a predetermined amount, so that the toe hill portion 18 of the sole is lifted. At this time, the body of the subject is guided to a slightly backward tilted posture by lifting the pinnacle 18. In this state, the center-of-gravity fluctuation is measured for a predetermined time, and the center-of-gravity fluctuation parameters such as the locus length, the rectangular area, and the average center-of-gravity position are calculated. Thereafter, the block 19b returns to the position of the horizontal surface of the platform 2.

このように本発明の第３の実施形態となる健康測定装置ではブロック１９ａ〜１９ｄが隆起することにより３種類の測定姿勢における重心動揺パラメータが算出されるので、これらのパラメータを用いて、筋力，関節柔軟性，平衡感覚機能等の被験者の運動能力に関係する健康指標を測定することができる。被験者の踵１７及び拇指丘部１８を持ち上げることで、水平面に立っている状態に比べてバランスが悪くなる。従って筋力，関節柔軟性，平衡感覚機能が優れている場合には、各姿勢における重心動揺パラメータ間の差は小さい。一方、筋力，柔軟性，平衡感覚機能が劣っている場合には各姿勢の重心動揺パラメータ間の差は大きく現れる。また、運動等トレーニングにより筋力，柔軟性，平衡感覚機能が向上すれば各姿勢の重心動揺パラメータ間の差は小さくなるため、トレーニング効果を簡易的かつ安全に計測することができる。なお、本実施形態では図８（ｃ）に示すようにブロックが足指にかかることなく拇指丘部１８のみを持ち上げることで足指屈筋力が働かないため、図６に示した傾斜板を用いた測定方法と比較して足関節のみの柔軟性評価が一層明確になる。 As described above, in the health measurement apparatus according to the third embodiment of the present invention, the blocks 19a to 19d are raised, so that the center-of-gravity fluctuation parameters in the three types of measurement postures are calculated. It is possible to measure health indicators related to the exercise ability of the subject such as joint flexibility and balance sensory function. Lifting the subject's heel 17 and phalange hill portion 18 makes the balance worse than when standing on a horizontal plane. Therefore, when the muscle strength, joint flexibility, and balance sensory function are excellent, the difference between the center-of-gravity sway parameters in each posture is small. On the other hand, when the muscle strength, flexibility, and balance sensory function are inferior, the difference between the center-of-gravity parameters of each posture appears greatly. In addition, if muscle strength, flexibility, and balance sensory function are improved by training such as exercise, the difference between the center-of-gravity sway parameters of each posture is reduced, so that the training effect can be measured easily and safely. In this embodiment, as shown in FIG. 8 (c), the toe flexor strength does not work by lifting only the toe hill portion 18 without the block being applied to the toes. Therefore, the inclined plate shown in FIG. 6 is used. Compared with the conventional measuring method, the flexibility evaluation of only the ankle joint becomes clearer.

〔第４の実施形態〕
次に、図９，図１０を参照して、本発明の第４の実施形態となる健康測定装置の構成について説明する。 [Fourth Embodiment]
Next, with reference to FIG. 9, FIG. 10, the structure of the health measuring apparatus used as the 4th Embodiment of this invention is demonstrated.

本発明の第４の実施形態となる健康測定装置では、ブロック１９ａ〜１９ｄの上面は通常時は図１０（ａ）に示すように踏台２の面とほぼ同一面になるように埋設されている。また図９に示すように、ブロック１９ａ及びブロック１９ｂとブロック１９ｃ及びブロック１９ｄとはエラストマー等の伸縮性材料により形成された連結部２４ａ〜２４ｄによりそれぞれ領域２３ａと領域２３ｂと連結されている。 In the health measuring apparatus according to the fourth embodiment of the present invention, the upper surfaces of the blocks 19a to 19d are normally embedded so as to be substantially flush with the surface of the platform 2 as shown in FIG. 10 (a). . As shown in FIG. 9, the blocks 19a and 19b and the blocks 19c and 19d are connected to the regions 23a and 23b by connecting portions 24a to 24d formed of an elastic material such as an elastomer, respectively.

〔健康指標測定時の動作〕
このような構成を有する健康測定装置は、以下のように動作することにより被験者の運動能力に関係する健康指標を測定する。すなわち、始めに被験者が電源スイッチ１１をオン状態に切り替え、図１０（ａ）に示すように踏台２に乗り、足固定位置ガイド１２ａ，１２ｂに足を合わせ、静止立位で保持する。次に、増幅器４ａ，４ｂ，４ｃ，４ｄがロードセル３ａ，３ｂ，３ｃ，３ｄの検出信号を増幅し、ＡＤ変換器５が所定のサンプリング周波数で増幅器４ａ，４ｂ，４ｃ，４ｄの増幅信号をＡＤ変換する。次に、演算部６が、ＡＤ変換器５の出力信号を重心位置座標に変換し、変換された重心位置座標を用いて軌跡長，矩形面積，平均重心位置等の重心動揺パラメータを算出する。 [Operation during health index measurement]
The health measuring device having such a configuration measures a health index related to the exercise ability of the subject by operating as follows. That is, first, the subject switches the power switch 11 to the on state, gets on the platform 2 as shown in FIG. 10 (a), puts his / her feet on the foot fixing position guides 12a and 12b, and holds in a stationary standing position. Next, the amplifiers 4a, 4b, 4c, 4d amplify the detection signals of the load cells 3a, 3b, 3c, 3d, and the AD converter 5 converts the amplified signals of the amplifiers 4a, 4b, 4c, 4d to AD at a predetermined sampling frequency. Convert. Next, the calculation unit 6 converts the output signal of the AD converter 5 into the center-of-gravity position coordinates, and uses the converted center-of-gravity position coordinates to calculate center-of-gravity fluctuation parameters such as a trajectory length, a rectangular area, and an average center-of-gravity position.

次に、被験者が切替スイッチ９を押下するのに応じて電磁弁３２ａ及び電磁弁３２ｂがそれぞれ開状態及び閉状態になる。そして、アクチュエータが作動することにより、図１０（ｂ）に示すように、ブロック１９ａが所定量踏み台２の水平面より沈降し、これに応じて領域２３ａもブロック１９ａに引っ張られて傾く。このとき被験者の姿勢は踵が下がることでやや後傾姿勢が誘導される。この状態で所定時間重心動揺を計測し、軌跡長，矩形面積，平均重心位置等の重心動揺パラメータが算出される。 Next, in response to the subject pressing down the changeover switch 9, the electromagnetic valve 32a and the electromagnetic valve 32b are opened and closed, respectively. Then, when the actuator is operated, as shown in FIG. 10B, the block 19a sinks from the horizontal surface of the footrest 2 by a predetermined amount, and the region 23a is also pulled by the block 19a and tilted accordingly. At this time, the posture of the subject is slightly backward tilted by lowering the heel. In this state, the center-of-gravity fluctuation is measured for a predetermined time, and the center-of-gravity fluctuation parameters such as the locus length, the rectangular area, and the average center-of-gravity position are calculated.

次に、被験者が切替スイッチ９を再び押すのに応じて、ブロック１９ａが踏台２の水平面の位置まで戻った後、電磁弁３２ａ及び電磁弁３２ｂがそれぞれ閉状態及び開状態になる。そしてアクチュエータ１０が作動することにより、図１０（ｃ）に示すように、ブロック１９ｂが所定量踏み台２の水平面より沈降し、領域２３ａもブロック１９ｂに引っ張られて傾く。このとき被験者の姿勢は拇指丘部が下がることでやや前傾姿勢が誘導される。この状態で所定時間重心動揺を計測し、軌跡長，矩形面積，平均重心位置等の重心動揺パラメータが算出される。その後、ブロック１９ｂが踏台２の水平面の位置まで戻る。 Next, in response to the subject pressing the changeover switch 9 again, the block 19a returns to the position on the horizontal surface of the platform 2, and then the electromagnetic valve 32a and the electromagnetic valve 32b are in a closed state and an open state, respectively. When the actuator 10 is actuated, as shown in FIG. 10 (c), the block 19b sinks from the horizontal surface of the footrest 2 by a predetermined amount, and the region 23a is also tilted by being pulled by the block 19b. At this time, the subject's posture is guided slightly forward by lowering the thumb hill. In this state, the center-of-gravity fluctuation is measured for a predetermined time, and the center-of-gravity fluctuation parameters such as the locus length, the rectangular area, and the average center-of-gravity position are calculated. Thereafter, the block 19b returns to the position of the horizontal surface of the platform 2.

このように本発明の第４の実施形態となる健康測定装置ではブロック１９ａ〜１９ｄが沈降することによって領域２３ａ及び領域２３ｂが傾くことにより複数の異なる姿勢における重心動揺パラメータが計測されるので、これらのパラメータを用いて、筋力、関節柔軟性、平衡感覚機能等の被験者の運動能力に関係する健康指標を測定することができる。なお、被験者の踵及び拇指丘を持ち上げることにより、水平面に立っている状態に比べて被験者の姿勢のバランスは悪くなる。ここで筋力，関節柔軟性，平衡感覚機能が優れている場合には、各姿勢における重心動揺パラメータ間の差は小さい。一方、筋力，柔軟性，平衡感覚機能が劣っている場合には各姿勢の重心動揺パラメータ間の差は大きく現れる。また、運動等トレーニングにより筋力，柔軟性，平衡感覚機能が向上すれば各姿勢の重心動揺パラメータ間の差は小さくなるため、トレーニング効果を簡易的かつ安全に計測することができる。また、本実施例では本体１の窪みに足を置くことになるため、万一の場合にも倒れにくく、安全に計測することができる。 As described above, in the health measurement device according to the fourth embodiment of the present invention, the blocks 19a to 19d are settled, and the region 23a and the region 23b are tilted. These parameters can be used to measure health indicators related to the subject's motor ability, such as muscle strength, joint flexibility, and balance sensory function. It should be noted that the balance of the posture of the subject is worsened by lifting the subject's heel and thumb hill compared to the state of standing on the horizontal plane. Here, when the muscle strength, joint flexibility, and balance sensory function are excellent, the difference between the center-of-gravity sway parameters in each posture is small. On the other hand, when the muscle strength, flexibility, and balance sensory function are inferior, the difference between the center-of-gravity parameters of each posture appears greatly. In addition, if muscle strength, flexibility, and balance sensory function are improved by training such as exercise, the difference between the center-of-gravity sway parameters of each posture is reduced, so that the training effect can be measured easily and safely. Further, in this embodiment, since the foot is placed in the hollow of the main body 1, it is difficult to fall down in the event of an emergency, and the measurement can be performed safely.

〔その他の実施形態〕

According to such a configuration, muscular strength, flexibility, and balance sensory function can be more strictly evaluated regardless of the shape of the foot.

図１３に示す健康測定装置では、踏台２内に埋設されたブロック１９ａ，ｂの上に踵１７及び拇指丘１８の生理的曲率に合った凹型の部材２０ａ，ｂが設けられている。このような構成によれば、被験者はこの部材に足の踵及び拇指丘を合わせることで簡単に足の位置決めをすることができる。なお、図１４に示すように土踏まず１４の生理的曲率に合わせた凸型の部材２１を設け、土踏まず１４を凸型の部材２１にあわせることによっても簡単に位置決めをすることができる。このようにすることで、位置ずれが少なくなり、測定精度が向上する。 In the health measuring apparatus shown in FIG. 13, concave members 20 a, b that match the physiological curvatures of the ridges 17 and the thumb hills 18 are provided on the blocks 19 a, b embedded in the platform 2. According to such a configuration, the subject can easily position the foot by aligning the foot heel and the toe hill with this member. As shown in FIG. 14, positioning can also be easily performed by providing a convex member 21 that matches the physiological curvature of the arch 14 and aligning the arch 14 with the convex member 21. By doing in this way, position shift decreases and measurement accuracy improves.

図１５に示す健康測定装置では、足の踵１７及び拇指丘１８のブロック１９ａ，１９ｂが交互に連続的に隆起するように構成されている。このような構成によれば、筋力，足関節，平衡感覚機能の追従性を評価することができる。なお、交互隆起には規則性があってもよいし、不規則であってもよい。このようにすることで動的なバランス能力と筋力、足関節柔軟性が一層詳細にわかる。 The health measuring device shown in FIG. 15 is configured so that the foot heel 17 and the blocks 19a and 19b of the thumb hill 18 are alternately raised continuously. According to such a configuration, it is possible to evaluate the following ability of muscle strength, ankle joint, and balance sensory function. Note that the alternating ridges may be regular or irregular. By doing so, dynamic balance ability, muscle strength, and ankle joint flexibility can be understood in more detail.

図１６（ａ），（ｂ）に示す健康測定装置では、ブロック１９ａ〜１９ｄの表面にそれぞれ足裏電極２２ａ〜２２ｄが設けられ、所定の周波数を有する微弱な交流電流を足裏電極２２ａ，２２ｃにより身体に流し、他方の足裏電極２２ｂ，２２ｄ間の電圧を測定することでインピーダンスを計測し、所定の変換式を用いることで内臓脂肪，筋肉量，水分量等の体組成成分を算出する。このような構成によれば、体組成成分と重心動揺パラメータを組み合わせることにより足裏から体調等の健康状態と運動による改善効果が一層詳細にわかるようになる。 In the health measuring device shown in FIGS. 16A and 16B, the sole electrodes 22a to 22d are provided on the surfaces of the blocks 19a to 19d, respectively, and a weak alternating current having a predetermined frequency is applied to the sole electrodes 22a and 22c. Is used to measure the impedance by measuring the voltage between the other sole electrodes 22b and 22d, and calculate body composition components such as visceral fat, muscle mass, and water content by using a predetermined conversion equation. .
