Description

本発明は、脳梗塞等の後遺症で麻痺した下肢の関節運動を自力で行う下肢運動椅子に関する。   The present invention relates to a lower limb exercise chair that performs joint movement of a lower limb paralyzed due to sequelae such as cerebral infarction by itself.

従来、下肢関節の機能回復訓練装置等は、罹患足に対して動力及び手駆動機構による発明がなされている。
特開２００２−２００１９３ 特開昭５７−１２８１５４ Conventionally, a function recovery training apparatus for a lower limb joint has been invented by a power and hand drive mechanism for an affected foot.

脳梗塞等の後遺症で麻痺した下肢は、放任すると筋及び腱の萎縮が進行して関節は凝固
し、運動が制限されて来るのは必然である。そこで、従来より関節の凝固を防止するため、罹患足に対して関節の運動を主体に物療士やリハビリ訓練士、又は機械、機具等により治療が行われて来た。 When the leg is paralyzed due to sequelae such as cerebral infarction, the atrophy of the muscles and tendons progresses when released and the joints coagulate, and movement is inevitably restricted. Therefore, conventionally, in order to prevent coagulation of the joint, the affected foot has been mainly treated by a physical therapist, a rehabilitation trainer, or a machine, equipment, etc.

その反面、罹患足だけに関心が向けられ、健足には何の対処も施されて来なかったのが現状である。     On the other hand, the current situation is that attention has been focused only on the affected foot and no measures have been taken on the healthy foot.

しかし長期間放任された状態では、健足も衰弱し次第に脚力は低下して最悪の場合起立すら困難になる事は明白である。     However, in the state of leaving for a long time, it is clear that healthy legs weaken and leg strength gradually decreases, making it difficult to stand up in the worst case.

歩行動作において、罹患足を補う健足の脚力は必要不可欠であり、健足の衰弱を防止する対策を施し、脚力の維持増進を計る事が重要である。     In walking motion, the leg strength of a healthy leg that supplements the affected leg is indispensable, and it is important to take measures to prevent the weak leg from deteriorating and to maintain and improve leg strength.

又、罹患した下肢は麻痺のため、自力では関節の運動動作が出来ない。そのため関節運動を行うにはすべて他力に頼るほか方法がないのが現状である。     In addition, since the affected lower limbs are paralyzed, the joints cannot move by themselves. For this reason, there is no way to rely on other forces for joint movement.

自分の意志ではどうすることもできない他人まかせの受動的対応は、心身に物体的な感覚が芽生え諦めから精気を失い廃人同様な姿である。     The passive response of others who can't do anything on their own will be like a caveman who has lost his spirit from giving up his physical and physical sensations.

麻痺した下肢の回復には時間を要し、長期間にわたって治療を受け続けなければならず、治療を持続し回復を効果的に導くには、本人の治療に対する意欲の高揚が必要である。     Recovery of the paralyzed lower limbs takes time and must be treated for a long period of time, and in order to sustain treatment and effectively lead to recovery, the person's motivation for treatment is required.

関節の凝固防止と血行を促す関節運動は、治療に欠く事の出来ない療法であり、治療に対する自立心の高揚と他力に頼る事なく自力で麻痺した関節の運動を行う事が出来る方法と、健足の衰弱を防止する対応策が課題である。     The joint movement that prevents coagulation of the joint and promotes blood circulation is a therapy that is indispensable for treatment, and it is possible to exercise the paralyzed joint on its own without relying on enhancement of self-reliance and other forces for treatment. Measures to prevent the weakness of healthy feet are an issue.

又、本発明の椅子に腰掛ける動作において、足乗せ台２が座部１１の先端より前方に位置した場合、体重の重心が座部１１より離れるため腰を下ろす時に不安定になる欠点がある。     Further, in the operation of sitting on the chair of the present invention, when the footrest 2 is positioned in front of the front end of the seat part 11, the center of gravity of the weight is separated from the seat part 11, so that there is a disadvantage that it becomes unstable when sitting down.

座部と背もたれを有する椅子１に、左右対に複数の上部回転軸（４、５）、支持具（６、７）、下部回転軸（８、９）を介して前後に動揺する足乗せ台２を設ける。     A chair 1 having a seat portion and a backrest, and a footrest that swings back and forth via a plurality of upper rotating shafts (4, 5), supports (6, 7), and lower rotating shafts (8, 9) in left and right pairs. 2 is provided.

左右対の支持具７に足乗せ台２の動揺に抵抗するバネ１２を設ける。     A spring 12 that resists shaking of the footrest 2 is provided on the pair of left and right supports 7.

左右対の支持具７を中間で分離して蝶番１０で接続する。     The pair of left and right supports 7 are separated in the middle and connected by a hinge 10.

以上の構成よりなる椅子１に座り足乗せ台２に罹患足と健足を乗せて健足で足乗せ台２を前後に動揺させ麻痺した下肢関節の運動を自力で行う。     Sitting on the chair 1 having the above configuration, the affected foot and the healthy foot are placed on the footrest 2 and the footrest 2 is shaken back and forth with the healthy foot to exercise the paralyzed lower limb joint by itself.

椅子１に座り、足乗せ台２に罹患足と健足の両足を乗せ、健足で足乗せ台２を揺らすことにより、罹患足の関節運動が発生し、他力に頼ることなく自力で、麻痺した罹患足の関節運動が実現できる。     Sitting on the chair 1, putting both feet of the affected foot and healthy foot on the footrest 2, and shaking the footrest 2 with healthy foot, the joint motion of the affected foot occurs, without relying on other forces, The joint movement of the paralyzed affected foot can be realized.

又、健足の力を利用するので健足の筋力が向上し、脚力の維持増進が計られる。     In addition, since the strength of the healthy leg is used, the muscle strength of the healthy leg is improved and the leg strength is maintained and increased.

足乗せ台２の支持具（６、７）の上部回転軸（４、５）及び下部回転軸（８、９）の回転軸が前後２点にあるため、足乗せ台２の前後の動揺に際して足乗せ台２の角度が強制的に変位する。たとえば前に出た時は鈍角となり、後ろに後退した時は鋭角となる。このため足関節の可動運動が発生し、足関節及び膝関節が同時に運動できる。     The upper and lower rotation shafts (4, 5) and the lower rotation shafts (8, 9) of the support (6, 7) of the footrest 2 have two rotation axes at the front and rear. The angle of the footrest 2 is forcibly displaced. For example, when it goes forward, it becomes an obtuse angle, and when it moves backward, it becomes an acute angle. For this reason, a movable movement of the ankle joint occurs, and the ankle joint and the knee joint can move simultaneously.

又、動揺する足乗せ台２の左右の支持具７に設けたバネ１２の抵抗により健足に負担が掛かり、健足の筋力を効果的に向上させることができる。   In addition, a load is applied to the healthy leg by the resistance of the springs 12 provided on the left and right support members 7 of the swinging footrest 2, and the muscle strength of the healthy leg can be effectively improved.

従来、罹患足の運動は、他力に頼る他方法がなく、自分の意志ではどうすることもできなかった他人まかせの受動的立場から一変して、自分の意志で能動的的に行う事ができるので実感が湧き、治療意欲が高揚する。   Traditionally, exercise of the affected foot has no other way to rely on other powers, and can be actively carried out with one's own will, changing from the passive position of others who could not do anything at their own will. So it feels real and motivates treatment.

椅子に座って行う事が出来る本療法は、体重が掛からないので運動に負担が掛からず、歩行動作が出来ない人、出来る人に関わらずすべての罹患者に対応することが可能である。   This therapy, which can be performed while sitting in a chair, does not burden the exercise because it does not require weight, and can be applied to all affected persons regardless of whether or not they can walk.

家の中で場所を選ばずできる本療法は、季節、天候、時間に関係なく自由に長時間、たとえばテレビを見ながら、しかも罹患足と健足の両足を同時に運動して、それぞれに改善することが出来る。   This therapy can be performed anywhere in the house, regardless of the season, weather, or time, and can be improved for a long time, for example while watching TV and exercising both affected and healthy feet at the same time. I can do it.

図２は、足乗せ台２を移動させた状態の側面図である。足乗せ台２の位置を移動させられることにより体重の重心を座部１１に近づけられるので、安定した腰掛け動作が出来る。
腰掛け後は、足を前方に移動させれば自然に足乗せ台２は元の位置にもどるので、そこで両足を乗せる。又、椅子１から離れるときは両足を足乗せ台２から離し足乗せ台２を足で移動させ体重の重心を座部１１に近づけて立てば安定した起立動作が出来る。 FIG. 2 is a side view of the state in which the footrest 2 is moved. By moving the position of the footrest 2, the center of gravity of the weight can be brought close to the seat 11, so that a stable seating operation can be performed.
After sitting, if the foot is moved forward, the footrest 2 naturally returns to its original position, so both feet are put there. Further, when leaving the chair 1, if both feet are separated from the footrest 2 and the footrest 2 is moved by the foot and the center of gravity of the weight is brought close to the seat portion 11, a stable standing motion can be achieved.

左右対の支持具６、７の上部回転軸４、５の位置は、椅子に座った状態の膝関節より上部に位置した方が足乗せ台２を前後に揺らしたとき動揺が大きく得られるので良い。   The upper rotary shafts 4 and 5 of the pair of left and right support members 6 and 7 are located above the knee joint in a chair sitting position, so that when the footrest 2 is swung back and forth, a large swing can be obtained. good.

左右対の支持具６、７の間隔は、１５〜２０センチメートル前後が適当である。なお、下部回転軸８、９より上部回転軸４、５の間隔が広ければ足乗せ台２が前後に動揺した時角度が大きく得られる。・   The distance between the pair of left and right supports 6 and 7 is suitably about 15 to 20 centimeters. In addition, if the space | interval of the upper rotating shafts 4 and 5 is wider than the lower rotating shafts 8 and 9, a big angle will be acquired when the footrest 2 shakes back and forth.・

左右対の支持具７の分離は、座部１１より下部で分離して蝶番１０で接続する。   The pair of left and right supports 7 are separated at the lower part from the seat part 11 and connected by a hinge 10.

足乗せ台２の動揺に抵抗するバネ１２は、左右対の支持具７を分離して蝶番１０で接続した上部と座部１１の左右の下部の間に設置した方が良い。そして座部１１の１３、１４、１５のフックに任意にバネの設定位置を変えることによってバネ１２の強弱が得られ各人の能力によって選択することが出来る。   The spring 12 that resists the shaking of the footrest 2 is preferably installed between the upper part where the pair of left and right support members 7 are separated and connected by a hinge 10 and the lower part of the left and right of the seat part 11. The spring 12 can be changed in strength by arbitrarily changing the setting position of the spring to the hooks 13, 14, and 15 of the seat 11, and can be selected according to the ability of each person.

座部と背もたれを有する椅子１に左右対に複数の上部回転軸４、５支持具６、７下部回転軸８、９を介して前後に動揺する足乗せ台２を設ける。   A chair 1 having a seat and a backrest is provided with a footrest 2 that swings back and forth via a plurality of upper rotary shafts 4, 5 supports 6, 7 lower rotary shafts 8, 9 in left and right pairs.

左右対の支持具７と座部１１の左右の下部の間に足乗せ台２の動揺に抵抗するバネ１２を設ける。   A spring 12 is provided between the pair of left and right supports 7 and the left and right lower portions of the seat 11 to resist the shaking of the footrest 2.

左右対の支持具７は座部１１より下部で分離して蝶番１０で接続する。   The pair of left and right supports 7 are separated from the lower portion of the seat 11 and connected by a hinge 10.

座部１１の左右の下部に、１３、１４、１５と任意にバネ１２のフックを設ける。   Hooks 13, 14, 15 and optionally a spring 12 are provided at the left and right lower portions of the seat 11.
