【発明の属する技術分野】
本発明は、生体の多関節多軸を連動させた動きである負荷動作により、患者ならびに、被験者の動きに制限の発見とその治療の確認をする負荷動作診断装置に関する。
【０００２】
【背景技術及び発明が解決しようとする課題】
ヒトの動きは２００以上の関節を連動させることにより、手先の微細な動きやスポーツ動作のようなダイナミックな動きを可能としている。ヒトの構造は、多くは左右対称であるにもかかわらず、その機能は利き手、利き足があるように非対称である。このことは個々人の特徴ある動きを実現する一方で、この動きの連動を制限する要因が生じた場合にはその特徴に変化がおこると考えられる。経絡テストは負荷動作を行い、骨、筋、関節の連動を制限している部位を特定する診断法で、これに基づくと制限を改善する鍼治療を行うことができる。
【０００３】
鍼の治療点の探索と、その治療効果を確認するための負荷動作を説明している書籍には、向野義人の経絡テスト（医歯薬出版、東京、１９９９）等がある。
また、左右のバランスを取ることを目的とした左右の荷重を測る機器は、既に販売されている。
【０００４】
動きの制限は、痛み、だるさ、ひきつり、張りの程度として主観的に表現される。生体の多関節多軸を連動させた動きに制限がある場合、主観的な愁訴による診断をおこなっている。
【０００５】
したがって、被験者の治療に対する評価ならびに、診断者の治療効果の確認が定性的になり、再現性に問題がある。
そこで、本発明の目的は、生体の多関節多軸を連動させた動きである負荷動作により、患者ならびに、被験者の動きに制限の発見とその治療の確認をする負荷動作診断装置を提供することにある。
【０００６】

【０００７】
左右荷重測定部で測定した左右荷重測定値を左右荷重測定値比較部により、比較することを特徴とする。
状態入力部によって、生体へ与える刺激の状態を入力し、刺激の状態に対応する少なくとも二回の左右荷重の測定をおこなうことを特徴とする。
【０００８】

【発明の実施の形態】
図１は、本発明の生体の多関節多軸を連動させた動きである負荷動作により、患者ならびに、被験者の動きに制限の発見とその治療の確認をする負荷動作診断装置である。
【００１２】
１０１は、経絡テストの基本姿勢と負荷動作の一つである肩関節の屈曲動作、つまり腕を下げた状態から肘を伸ばしたまま腕を挙上する動作を指示する負荷動作指示部である。例えば、負荷動作を規定するため６０拍／分のメトロノーム音にあわせ、基本姿勢から４秒間で負荷動作を終了させるものである。
【００１３】
図３に経絡テストの基本姿勢と負荷動作の一つである肩関節の屈曲動作、つまり腕を下げた状態から肘を伸ばしたまま腕を挙上する動作を示した。
１０２は、左右２枚の床反力計で、左右の足の荷重を別々に測定する左右荷重測定部である。
１０３は、赤外線カメラで、例えば６台を直径４５００ｍｍの円周上に、１５００〜２０００ｍｍの高さで等間隔に設置し、サンプリング周波数１２０Ｈｚで床反力計のアナログ信号と同期してそれぞれの動作毎に測定可能なものとした。
１０４は、左右荷重測定部１０２のデータを解析する装置で、図２は、１０４におけるデータ解析のブロック図である。

【００１６】
ここで具体的にこの装置を使った実験を以下に詳細に述べる。
被検者は卓球競技歴７年以上の男性２０名である。被検者の利き手、利き足を表１に示した。被験者の両手首ならびに両側の肩と骨盤に直径９ｍｍのマーカを設定した。また表１には被検者の利き手、利き足を示すとともに、鍼刺激前の基本姿勢におけるＺ軸の肩と腰のマーカの位置を示した。左右の肩のマーカの位置に有意差を示したのはＭ２２Ｃ，　Ｍ１９Ｄ，　Ｍ１８Ｅ，　Ｍ２１Ｇ，　Ｍ１９Ｈ，　Ｍ２１Ｉ，　Ｍ２１Ｊ，　Ｍ１８Ｋ，　Ｍ１８Ｌ，　Ｍ２０Ｍ，　Ｍ２０Ｏ，　Ｍ２１Ｐ，　Ｍ２１Ｑ，　Ｍ２１Ｒ　の１４名であった。一方、左右の腰のマーカの位置に有意差を示したのはＭ１８Ａ，　Ｍ１８Ｂ，　Ｍ２２Ｃ，　Ｍ１９Ｄ，　Ｍ２０Ｆ，　Ｍ２１Ｇ，　Ｍ２１Ｉ，　Ｍ１８Ｋ，　Ｍ２０Ｍ，　Ｍ２０Ｏ，　Ｍ２１Ｐ，　Ｍ２１Ｑ，　Ｍ１８Ｔの１３人であった。肩腰ともに左右差があったのは９人で、肩のみ左右差があった例は５例で、腰のみに左右差を認めたのは３例であった。肩腰ともに左右差を認めなかったのは２例に過ぎず、被検者のほとんどで基本姿勢に片寄りがあった。
【００１７】

【００１８】
表２は鍼刺激後の基本姿勢における肩と腰のマーカの左右差を示したものである。肩のマーカの左右差が新たに有意となるか有意な左右差が消失するなどの変化したのはＭ１８Ｂ，　Ｍ１９Ｄ，　Ｍ２０Ｆ，　Ｍ２１Ｐの４例であった。腰のマーカの左右差はＭ２２Ｃ，Ｍ１８Ｅ，　Ｍ１８Ｋ，　Ｍ１８Ｌ，　Ｍ２１Ｐの５例で新たに有意となるか有意な左右差が消失するなどの変化を示した。肩と腰の変化がともにおこったのはＭ２１Ｐのみであった。鍼刺激後に基本姿勢に変化を生じたのは８例であり、鍼刺激が姿勢の変化を起こしうると推測された。
【００１９】

【００２０】
表３は刺激前の基本姿勢における床反力の左右差をみたものである。Ｍ２２Ｃ，　Ｍ１９Ｄ，　Ｍ２１Ｊ，　Ｍ１８Ｔ　において有意な差がみられた。表４は刺激後の基本姿勢における床反力の左右差をみたものである。Ｍ２２Ｃ，　Ｍ１９Ｄ，　Ｍ２１Ｊ，　Ｍ１８Ｔ　において刺激前に観察された有意差が消失した。刺激後Ｍ２０Ｏ，　Ｍ２１Ｐ，　Ｍ２１Ｒにおいて新たに有意な左右差を生じた。合計すると７例において鍼刺激後に基本姿勢における左右差に変化を生じた。鍼刺激が重心移動に変化を起こしうると推測された。鍼刺激後に基本姿勢に変化を生じた８例のうち、床反力の左右差にも変化が及んだのはＭ２２Ｃ，　Ｍ１９Ｄ，　Ｍ２１Ｐの３例のみであった。Ｍ２１Ｊ，　Ｍ１８Ｔ，　Ｍ　２０Ｏ，　Ｍ２１Ｒの４例は鍼刺激により肩や腰のマーカの有意な左右差が生じなかったにもかかわらず床反力計の左右差には有意な変化を生じた。
【００２１】

【００２２】

【００２３】
表５は、表１から表４の鍼刺激前後での肩腰のマーカ位置，ならびに左右床反力の有意差を被験者毎にまとめたものを示す。刺激前の基本姿勢において２０名中１４名は肩のマーカの位置が有意な左右差を示した。右肩あがりは２名、右肩さがりは１２名であり、卓球選手は基本姿勢ですでに左右の肩の位置に片寄りがあった。１３名は腰のマーカの位置に有意な左右差をみとめた。右腰あがりは６名、右腰さがりは７名であり、基本姿勢ですでに左右の腰の位置に片寄りがあった。肩腰のマーカの双方に左右差がないのは２名のみであり、卓球選手の基本姿勢は肩と腰の双方あるいはいずれかに片寄りがあると考えられた。鍼刺激後にはこの片寄りに変化が観察され、刺激前にみられた肩や腰のマーカの左右差が消失したり、新たに有意差が認められるなど鍼刺激が姿勢の変化を起こしていることが観察された。肩腰とも、肩あるいは腰いずれかの位置の片寄りとともに基本姿勢における床反力に有意な左右差がみられたのは４名であった。この４名は鍼刺激後，床反力の左右の有意差が消失した。さらに、新たに３名において有意差が出現した。このことは鍼刺激が重心移動に変化を起こすことを示している。鍼刺激後に基本姿勢の変化を生じた８名のうち床反力にも有意な変化を示したのはＭ２２Ｃ，Ｍ１９Ｄ，Ｍ２１Ｐの３名であり、この３名の肩関節時の床反力の軌跡を図４に示した。
【００２４】

【００２５】
Ｍ１９Ｄのように鍼刺激後も初期の左右差が維持される例やＭ２２Ｃ，Ｍ２１Ｐのように肩関節屈曲にともなって床反力の左右差が拡大し、動作の終了にともない左右差が減少した例もあった。
１本の鍼刺激でも基本姿勢における肩や腰のマーカの位置や床反力の左右差に影響を及ぼすと考えられた。
【００２６】
本実験では利き手、利き足といった機能の片寄りと長年にわたる同じ動作の繰り返しがヒトの基本姿勢に影響をおよぼしていることを競技歴７年以上の卓球選手を対象に三次元計測で検討した。その結果、卓球選手においては基本姿勢で肩や腰のマーカの位置や床反力の左右差を認め、長年にわたる同じ動作の繰り返しが姿勢に影響を及ぼしていると考えられた。鍼刺激はこれらの片寄りに対して影響を及ぼし、有意差を消失させたり、新たな有意差を生じさせた。１本の鍼刺激でも基本姿勢における肩や腰のマーカの位置や床反力の左右差に影響を及ぼすと考えられた。また、鍼刺激により基本姿勢および床反力双方に変化が引き起こされた例の肩関節屈曲開始から終了までの床反力の軌跡を観察したところ、鍼刺激は軌跡全体へ影響を及ぼしていた。鍼刺激はヒトの動きに影響を及ぼすと考えられた。
【００２７】
本発明によれば、負荷動作指示手段により、負荷動作をおこなわせ、負荷動作に対する左右荷重測定の結果を記憶し、刺激前後の負荷動作に対する左右荷重測定結果の時間的な荷重変化をそれぞれ告知する負荷動作診断装置を提供することができる。
また、負荷動作指示手段により、負荷動作をおこなわせ、負荷動作に対する左右荷重測定の結果を記憶し、刺激前後の負荷動作に対する左右荷重測定結果の
時間的な荷重変化の比較をおこない、差が有ればその結果を刺激の効果として告知する負荷動作診断装置を提供することができる。
【００２８】
【発明の効果】
以上説明したように、本発明の負荷動作診断装置によれば、生体の多関節多軸を連動させた動きに制限がある場合の負荷動作に対する診断を定量的に行うことができる。

BACKGROUND ART AND PROBLEMS TO BE SOLVED BY THE INVENTION
Human movements enable dynamic movements such as minute movements of hands and sports movements by linking more than 200 joints. Although the structure of humans is often symmetrical, its function is asymmetrical with a dominant hand and a dominant foot. While this realizes the characteristic movement of each individual, it is considered that when a factor that restricts the interlocking of the movement occurs, the characteristic changes. The meridian test is a diagnostic method that performs a load operation and identifies a part that restricts the interlocking of bones, muscles, and joints. Based on this, acupuncture can be performed to improve the restriction.
[0003]
Books describing the search for the treatment points of acupuncture and the load operation for confirming the treatment effects include the Meridian Test by Yoshito Mukono (Medical Dentistry Publishing, Tokyo, 1999).
Instruments for measuring left and right loads for the purpose of balancing left and right have already been sold.

Movement limitations are subjectively expressed as pain, sluggishness, tightness, and degree of tension. If there is a restriction on the movement of the living body linked with the multiple joints and multiple axes, a diagnosis is made based on subjective complaints.
[0005]
Therefore, the evaluation of the treatment of the subject and the confirmation of the treatment effect of the diagnostician become qualitative, and there is a problem in reproducibility.
Therefore, an object of the present invention is to provide a load operation diagnostic apparatus that detects a limitation on the movement of a patient and a subject and confirms a treatment thereof by a load operation that is a movement in which the articulated multi-axis of a living body is linked.

[0016]
Here, an experiment using this device is specifically described in detail below.
The subjects were 20 men who have played table tennis for more than 7 years. Table 1 shows the dominant hand and dominant foot of the subject. Markers with a diameter of 9 mm were set on both wrists and both shoulders and pelvis of the subject. Table 1 shows the dominant hand and dominant foot of the subject and the positions of the Z-axis shoulder and waist markers in the basic posture before acupuncture stimulation. Fourteen M22C, M19D, M18E, M21G, M19H, M21I, M21J, M18K, M18L, M20M, M20O, M21P, M21Q, M21R showed significant differences in the positions of the left and right shoulder markers. On the other hand, 13 persons of M18A, M18B, M22C, M19D, M20F, M21G, M21I, M18K, M20M, M20O, M21P, M21Q, and M18T showed significant differences in the positions of the left and right waist markers. Nine people had left-right differences in shoulder and waist, five cases had left-right differences only in shoulders, and three cases had left-right differences only in waist. Only two cases showed no difference in shoulder and waist, and most of the subjects had a bias in the basic posture.
[0017]

[0018]
Table 2 shows the difference between the left and right markers of the shoulder and the waist in the basic posture after the acupuncture stimulation. In four cases, M18B, M19D, M20F, and M21P were changed such that the left-right difference of the shoulder marker became newly significant or the significant left-right difference disappeared. The left and right difference of the waist marker showed a change such as a new significance or a disappearance of the significant left / right difference in five cases of M22C, M18E, M18K, M18L and M21P. Only M21P had both shoulder and hip changes. In 8 cases, the basic posture changed after acupuncture stimulation, and it was speculated that acupuncture stimulation could cause a change in posture.
[0019]

[0020]
Table 3 shows the left-right difference in floor reaction force in the basic posture before stimulation. Significant differences were observed in M22C, M19D, M21J, and M18T. Table 4 shows the left-right difference of the floor reaction force in the basic posture after stimulation. In M22C, M19D, M21J, and M18T, the significant difference observed before stimulation disappeared. After the stimulation, a significant left-right difference was newly generated in M20O, M21P, and M21R. In total, the left-right difference in the basic posture changed after acupuncture stimulation in 7 cases. It was speculated that acupuncture could change the center of gravity shift. Of the eight cases in which the basic posture changed after acupuncture stimulation, only three cases, M22C, M19D, and M21P, changed the left-right difference in floor reaction force. In the four cases of M21J, M18T, M20O, and M21R, there was a significant change in the left-right difference of the floor reaction force meter even though the acupuncture stimulation did not cause a significant left-right difference of the shoulder and waist markers.
[0021]

[0022]

[0023]
Table 5 shows the marker positions of the shoulders and waist before and after the acupuncture stimulation in Tables 1 to 4, and the significant difference between the left and right floor reaction forces for each subject. In the basic posture before stimulation, 14 of the 20 subjects showed significant left and right differences in the positions of the shoulder markers. There were 2 right shoulder lifters and 12 right shoulder lifters, and table tennis players were already biased in the left and right shoulder positions in the basic position. Thirteen found significant left and right differences in the position of the waist markers. There were six right hips and seven right hips, and there was already a bias in the left and right waist positions in the basic posture. Only two persons had no difference between the left and right markers on the shoulders and waist, and it was considered that the basic attitude of the table tennis player was biased on either or both of the shoulders and waist. After acupuncture stimulation, a change was observed in this offset, and the acupuncture stimulation caused a change in posture, such as disappearance of left and right differences in shoulder and waist markers seen before stimulation and a new significant difference was observed. Was observed. Four subjects showed significant left and right differences in floor reaction force in the basic posture, as well as in the shoulder and waist, with either the shoulder or the waist offset. After acupuncture stimulation, these four subjects lost the significant difference in floor reaction force between left and right. Furthermore, a significant difference appeared in three new subjects. This indicates that acupuncture stimulates changes in center of gravity shift. Of the eight subjects who had changed their basic posture after acupuncture stimulation, three subjects M22C, M19D and M21P also showed significant changes in floor reaction force. The trajectory is shown in FIG.
[0024]

[0025]
The left-right difference in floor reaction force increases with shoulder joint bending, as in the case where the initial left-right difference is maintained after acupuncture stimulation as in M19D, and as in M22C and M21P, and the left-right difference decreases with the end of the movement. There were examples.
It was thought that even one acupuncture stimulation affected the position of the shoulder and waist markers and the left-right difference in floor reaction force in the basic posture.
[0026]
In this experiment, three-dimensional measurement was performed on table tennis players with more than seven years of experience in sports to examine the effects of the bias of functions such as the dominant hand and the dominant foot and the repetition of the same movement for many years on human basic posture. As a result, in table tennis players, differences in the positions of the shoulder and waist markers and the floor reaction force were recognized in the basic posture, and it was considered that repeated movements over the years affected the posture. Acupuncture had an effect on these deviations, eliminating significant differences or creating new ones. It was thought that even one acupuncture stimulation affected the position of the shoulder and waist markers and the left-right difference in floor reaction force in the basic posture. When the locus of the floor reaction force from the start to the end of flexion of the shoulder joint was observed in the case where both the basic posture and the floor reaction force were changed by the acupuncture stimulation, the acupuncture stimulation affected the entire trajectory. Acupuncture stimulation was thought to affect human movement.
