Description
本発明は、スポーツなどの関節運動にかかわる特定動作習得練習において使用され、特に、手首関節の可動方向を特定の方向に固定して、着用者に該特定方向の動作を選択的に練習させ習得を促す、練習用手首関節固定具に関する。 The present invention relates to a wrist joint fixation device for training, which is used in training to learn specific movements related to joint movements in sports and the like, and in particular fixes the direction of movement of the wrist joint in a specific direction, allowing the wearer to selectively practice and learn movements in that specific direction.
従来、手首に打撲、捻挫、腱鞘炎を発症した場合の保存療法として、或いは、卓球、テニス等のスポーツをする際に手首を痛めないようにその予防として、手首をサポーターで保護するのが一般的であり、種々のサポーターが提案されている。 Conventionally, it has been common to protect the wrist with a wrist support as a conservative treatment for wrist bruises, sprains, and tendonitis, or to prevent wrist injuries when playing sports such as table tennis or tennis, and various types of wrist support have been proposed.
例えば、特開２０１３－２２３４４号公報にあるように、手関節、特にＴＦＣＣ（三角繊維軟骨複合体）損傷の痛みの軽減や治療のために用いられ、手関節部位からずれることなく長期間にわたって安定的に固定し、手関節の動きを十分に抑制することを目的とした手関節固定具があるが、本発明の練習用手首関節固定具のように手首関節を特定の方向に固定して特定方向の運動を補助するものではない。 For example, as described in JP 2013-22344 A, there is a wrist joint fixation device that is used to relieve pain and treat injuries to the wrist joint, particularly to the TFCC (triangular fibrocartilage complex), and is intended to stably fix the wrist joint for a long period of time without slipping from the wrist joint and to sufficiently suppress movement of the wrist joint. However, unlike the wrist joint fixation device for training of the present invention, it does not fix the wrist joint in a specific direction to assist movement in a specific direction.
また、特開２００５－５４９号公報にある手首拘束用サポーターは、手首に打撲、捻挫、腱鞘炎を発症した場合の保存療法として、手首の動きを拘束するためのサポーターであり、第１指、手の甲及び掌側に支持体を備えない。 In addition, the wrist restraint supporter disclosed in JP-A No. 2005-549 is a supporter for restraining the movement of the wrist as a conservative treatment when the wrist develops a bruise, sprain, or tendonitis. and no support on the palm side.
さらに、特開２０１０－１３１０６６号公報にある肘用サポーターは、肘関節近傍を適切に保護及び固定できる肘用サポーターであるが、手首関節を支持するものではない。 Furthermore, the elbow support in JP 2010-131066 A is an elbow support that can adequately protect and stabilize the area near the elbow joint, but does not support the wrist joint.
さらにまた、特開２００４－１０５５４４のゴルフ練習用手袋や特開２００１－３２１４７９のゴルフ練習用矯正具等があるが、それらはゴルフのスイング矯正として、手首の動きを拘束するためのものであり、手の掌側に支持体を備えない。 Furthermore, there are golf practice gloves disclosed in JP 2004-105544 and golf practice correction devices disclosed in JP 2001-321479, but these are intended to restrict wrist movement as a form of golf swing correction and do not have a support on the palm side of the hand.
さらに、実用新案登録番号第３０２８５２０号公報にある、ゴルフ用手首固定装具は、ゴルフクラブをスイングする際に、手首がブレてクラブヘッドが揺れることが無いようにするための手首固定装具に関するものであり、手首関節の特定方向への運動を促すものではない。 Furthermore, the wrist immobilization device for golf described in Utility Model Registration No. 3028520 relates to a wrist immobilization device designed to prevent the wrist from shaking and the club head from swaying when swinging a golf club, and is not designed to encourage movement of the wrist joint in a specific direction.
すなわち、現行の固定具は、ユーザーの手首関節の特定方向の運動を選択的に強化する目的のものではない。 That is, current fixtures are not intended to selectively enhance movement of a user's wrist joint in a particular direction.
特定の手首関節の動作が要求される運動を習得しようとする競技者にとって、個人差により特定方向の動きの習得が、困難であったり、時間を要したりする。これは潜在的な能力を有する競技者の競技継続のモチベーションを阻害することがある。また、この動作を競技者に習得させる指導者にとっても、限られた時間内で一定レベルの指導を計画する際の障害となっていた。 For athletes trying to learn exercises that require movements of specific wrist joints, it may be difficult or time consuming to learn movements in specific directions due to individual differences. This can hinder the motivation of athletes with potential to continue competing. Furthermore, this poses an obstacle for instructors who want athletes to learn this movement when planning instruction at a certain level within a limited amount of time.
スポーツにおいて、手首関節の特定方向への運動の強化が要求される。しかしながら、手首関節の可動は「撓屈・尺屈・背屈・掌屈」の４方向と、肘関節の動きと連動し、様々な方向へ可動なため、ユーザーはどの関節を使って動かしているのか意識していないことが多い。 In sports, there is a demand for strengthening the movement of the wrist joint in a specific direction. However, since the wrist joint can move in four directions (flexion, ulnar flexion, dorsiflexion, and palmar flexion) and in various directions linked to the movement of the elbow joint, users are often unaware of which joint they are using to move it.
また、ユーザーによってその方向の得意不得意が発生し、特定方向への運動の強化を図ることが容易ではない。これでは、学校体育や部活動、スポーツ教室などの指導現場においても同様の問題が生じる。 Additionally, users have different strengths and weaknesses in certain directions, making it difficult to strengthen movement in a particular direction. This causes similar problems in instructional settings such as school physical education, club activities, and sports classes.
つまり特定方向の手首関節の運動の習得速度においてユーザー差が生じ、特に習得難易度の高い運動については、限られた指導時間の間に統一的な指導成果を達成することが困難になっていると考えられる。 In other words, differences occur between users in the speed at which they learn wrist joint movements in specific directions, making it difficult to achieve uniform teaching results within the limited teaching time, especially for movements that are difficult to learn. it is conceivable that.
そこで、本発明は、手首関節の特定方向の動きを選択的に強化することができる手首関節固定具を提供することを目的とする。 SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a wrist joint fixation device that can selectively strengthen the movement of the wrist joint in a specific direction.
例えば、バドミントンストロークにおける代表的な技術としては、肘関節の動きの一つである回内及び回外を使って行う。多種あるストローク動作の内、フォアハンドストロークの場合、一度回外の動きでテークバックし、その反動を使って一気に回内を使ってインパクト、フォロースルーに至る動作を行う。バックハンドストロークの場合は、その逆となり、一度回内の動きでテークバックし、その反動を使って一気に回外を使ってインパクト、フォロースルーに至る動作となる。 For example, a typical technique in badminton strokes is to use pronation and supination, which are movements of the elbow joint. Of the many types of stroke movements, in the case of a forehand stroke, the player takes the ball back with a supination movement, then uses the momentum to pronate in one go to impact and follow through. In the case of a backhand stroke, the opposite is true, where the player takes the ball back with a pronation movement, then uses the momentum to supinate in one go to impact and follow through.
このようなストローク動作をスムーズ行うには、安定的なグリップの持ち方や、ユーザーの正確な動作、ラケットとの間で相対的な動きが噛み合う必要がある。例えば、ラリーのスピードが速くなればなるほど、ストローク動作を高速に行う必要があるが、テークバックが間に合わず、返球が難しくなる。 In order to perform such stroke motions smoothly, it is necessary to have a stable grip, precise movements by the user, and a relative movement between the racket and the racket. For example, the faster the rally speed, the faster the stroke action must be performed, but the takeback cannot be done in time, making it difficult to return the ball.
また、高難度ストローク技術の一つである、ハイバックストロークではユーザーはコート後方へ追い込まれた状況な為に、十分なテークバックをとる時間がなく、より習得を難しくしている。 In addition, in the high back stroke, which is one of the more difficult stroke techniques, the user is forced to the back of the court, so there is no time to take a sufficient take back, making it even more difficult to master.
ハイバックストロークやバックハンドストロークの習得は、習得する方法及びその対応について、指導者の創意工夫とユーザーの努力によって習得できる状況で、いわゆる技能として習得する状況となっていて、すべてのユーザーにそのような環境を望むことはできない。 Learning the high back stroke and backhand stroke can be learned through the ingenuity of the instructor and the effort of the user, and all users are expected to learn how to do it and how to handle it. You can't expect a good environment.
そのような環境下において、不必要なテークバックを使わないストローク技術とその習得方法（Kawakita Method）が開発されている。 In this environment, a stroke technique that does not use unnecessary backswings and a method for learning it (the Kawakita Method) have been developed.
手首関節は、４方向への動き「撓屈・尺屈・背屈・屈曲」があり、手首関節の不要な動きを制限したストローク技術とその習得方法（Kawakita Method）において、横方向の動きである、撓屈状態から尺屈側へ手首を動かすことにより、バックハンドドライブ動作となる。 The wrist joint has movements in four directions: flexion, ulnar flexion, dorsiflexion, and flexion, and in the stroke technique and learning method (Kawakita Method) that limits unnecessary movements of the wrist joint, it is possible to move in the lateral direction. By moving the wrist from a certain flexed state to the ulnar flexed side, a backhand drive motion is created.
また、高難度ストローク技術の一つであるハイバックストロークは、手首関節を背屈に保ちながら撓屈状態から尺屈側へ手首を動かし、続いて肘関節で回外動作によって実現している。 The high back stroke, which is one of the more difficult stroke techniques, is achieved by moving the wrist from a flexed state to an ulnar side while keeping the wrist joint dorsiflexed, and then by supinating the elbow joint.
しかしながら、このストローク技術を習得するためには、不必要なテークバックを使わないストローク技術とその習得方法（Kawakita Method）を学ぶ必要があり、従来の指導と同様ユーザーの環境により習得が難しい。 However, in order to learn this stroke technique, it is necessary to learn a stroke technique that does not use unnecessary takebacks and how to learn it (Kawakita Method), which, like traditional instruction, is difficult to learn depending on the user's environment.
上記問題を解決するために、本発明の練習用手首関節固定具を提供することで、手首関節の不要な動きを制限したストローク技術とその習得方法（Kawakita Method）を学んだのと同じ効果が期待でき、特定方向の動きを選択的に強化することが可能となり、ユーザーへ特定の手首関節の運動を強化し、効率的な運動習得を促すものである。 In order to solve the above problems, the present invention provides a wrist joint immobilization device for practice that can be expected to have the same effect as learning a stroke technique that limits unnecessary wrist joint movement and the method for learning it (Kawakita Method), making it possible to selectively strengthen movement in a specific direction, strengthening the movement of a specific wrist joint for the user and encouraging efficient exercise acquisition.
本発明の練習用手首関節固定具を使用することで、短期間で効率的に習得すること、また、習得させることが可能になるため、競技者のモチベーションを高めることができ、また、より高いレベルの競技指導を計画しやすくなる。 By using the training wrist joint fixation device of the present invention, it is possible to learn efficiently in a short period of time. It becomes easier to plan competition instruction for different levels.
ここでの競技において要求される手首関節の特定の動作とは、これまで上級競技者のみにしか指導できなかったハイレベルと考えられていた動作を対象としており、この動作をストローク練習の初期から開始し、習得させることで、より上級レベル競技者への早期育成が可能になる。 The specific wrist joint movements required in this competition are movements that have previously been considered high-level movements that only advanced athletes could be taught, and by starting to teach these movements from the beginning of stroke practice and having players master them, it will be possible to quickly develop into more advanced-level athletes.
また、上級競技者においても、本発明の練習用手首関節固定具を装着してストローク練習を行うことにより、より精度の高いストローク習得が可能になる。 Moreover, even advanced athletes can learn strokes with higher precision by practicing strokes while wearing the wrist joint fixation device for practice of the present invention.
本発明に係る練習用手首関節固定具をバドミントンのストローク習得練習時に利き手に装着すると、利き手の甲側被覆部に内包された、少なくとも７０度から最大９０度の背屈に固定できる剛性材と、掌側被覆部に内包された、少なくとも７０度から最大９０度の背屈に固定できる剛性材と、甲側被覆部の尺骨側に内包された、手首が尺屈側へ動きすぎないように制限する適宜の剛性材によって手首関節の動きを制限されることから、手首を撓屈状態から尺屈側へ動かすことにより、バドミントンのハイバックストロークに必要な関節の運動をユーザーに集中的に強化および習慣づけ、適切なストロークフォームの習得を効率的に可能にする。 When the wrist joint fixation device for practice according to the present invention is worn on the dominant hand during badminton stroke learning practice, the rigid material can be fixed to dorsiflexion of at least 70 degrees to a maximum of 90 degrees, which is included in the back side covering of the dominant hand; A rigid material contained in the palm side covering part that can be fixed to dorsiflexion of at least 70 degrees to a maximum of 90 degrees, and a rigid material contained in the ulnar side of the back side covering part to prevent the wrist from moving too much to the ulnar side. Since the movement of the wrist joint is restricted by an appropriate rigid material, by moving the wrist from a flexed state to an ulnar flexed side, the user can intensively strengthen and habituate the joint movement required for badminton's high back stroke. This will enable you to learn appropriate stroke form efficiently.
図１から図７に示す実施例１の練習用手首関節固定具１は、バドミントンのストローク技術、特に習得が困難とされる高難度ストローク技術であるハイバックストローク技術習得に使用するもので、利き手の甲側の手関節部分から中手骨部分を覆うように装着される甲側被覆部２と少なくとも掌側の手首関節部分を覆うように被着される掌側被覆部５とを備え、甲側被覆部の下端突出部４に、手首に巻きつけるベルト部３からなり、上記甲側被覆部２と掌側被覆部５に手首の背屈の角度を固定するため適宜の剛性材１３と剛性材１１を内包し、上記甲側被覆部２の尺骨側に、手首の撓屈から尺屈への動きを制限する適宜の剛性材１２が内包されている。 The wrist joint fixation device 1 for practice according to the first embodiment shown in FIGS. 1 to 7 is used for learning badminton stroke techniques, especially the high back stroke technique, which is a highly difficult stroke technique that is considered difficult to acquire. The back side covering part 2 is attached to cover the wrist joint part on the back side to the metacarpal bone part, and the palm side covering part 5 is attached to cover at least the wrist joint part on the palm side. The lower end protrusion 4 of the sheathing part is made up of a belt part 3 that is wrapped around the wrist, and the instep side sheathing part 2 and the palm side sheathing part 5 are made of an appropriate rigid material 13 and a rigid material for fixing the angle of dorsiflexion of the wrist. 11, and a suitable rigid material 12 for restricting the movement of the wrist from flexion to ulnar flexion is included on the ulna side of the instep side covering portion 2.
剛性材１１及び１３は、厚さ２ｍｍのアクリル製プレート又は塩化ビニル製プレート等の硬質プラスチック製プレートで、手首の背屈を少なくとも７０度から最大９０度に固定できるよう形成及び配置されている。 The rigid members 11 and 13 are hard plastic plates, such as 2 mm thick acrylic or polyvinyl chloride plates, that are shaped and positioned to fix the wrist at dorsiflexion at least 70 degrees and up to 90 degrees.
剛性材１２は、厚さ２ｍｍのアクリル製プレート又は塩化ビニル製プレート等の硬質プラスチック製プレートで、手首の尺屈を制限するため少なくとも、手首の豆状骨を亘って掌の第５指側の側部に延在し得るよう形成及び配置されている。 The rigid member 12 is a hard plastic plate, such as an acrylic plate or a vinyl chloride plate, with a thickness of 2 mm, and extends at least across the pisiform bone of the wrist on the fifth finger side of the palm in order to limit ulnar flexion of the wrist. It is formed and arranged so that it can extend laterally.
甲側被覆部２の下部突出部４の裏面と掌側被覆部５表面に互いに係止しうる係止手段９及び１０が設けられている。 The back surface of the lower protrusion 4 of the back side covering part 2 and the surface of the palm side covering part 5 are provided with locking means 9 and 10 that can lock together.
手首に巻きつけるベルト部３は、手首に巻きつけたときに重なり合う表面側３ａと裏面側２ｂに面ファスナーの雌面と雄面が配されたナイロン繊維製の非伸縮性ベルトで形成されており、その片端部が甲側被覆部２の下部突出部４の表面に取り付けられたプラスチック製の角形リングからなるベルト引締め用バックル１４に固定され、自由端となる他端側を手首の先端部に巻き付けてからバックル１４に差し通して折り返し、その折り返した他端側を引っ張って巻締めた状態として表面側３ａと裏面側３ｂを面ファスナーで接着することにより、甲側被覆部２を手首に締め止めるようになっている。 The belt part 3 to be wrapped around the wrist is formed of a non-stretchable belt made of nylon fiber, with female and male surfaces of a hook-and-loop fastener arranged on the front side 3a and back side 2b, which overlap when wrapped around the wrist. , one end of which is fixed to a belt tightening buckle 14 made of a square plastic ring attached to the surface of the lower protrusion 4 of the instep covering part 2, and the other free end is attached to the tip of the wrist. After wrapping it, insert it through the buckle 14, fold it back, pull the other folded end side to tighten it, and then glue the front side 3a and the back side 3b with a hook-and-loop fastener to tighten the instep side covering part 2 around the wrist. It's supposed to stop.
甲側被覆部２は、ネオプレンゴムなどの衝撃吸収材料からなり、表面及び裏面の生地はナイロン製からなる。 The upper covering part 2 is made of a shock-absorbing material such as neoprene rubber, and the front and back fabrics are made of nylon.
以上のように構成された練習用手首固定装具１を利き手に装着すると、剛性材１１及び１３を内包した、甲側被覆部２と掌側被覆部５によって、手首の背屈が少なくとも７０度から最大９０度に制限され、図７（ａ）から（ｃ）のような手首の動作となり、高難易度なストローク技術である、ハイバックストローク動作の練習を効率よく選択的強化が図れる。 When the training wrist fixation brace 1 configured as described above is worn on the dominant hand, the dorsiflexion of the wrist is prevented from at least 70 degrees by the back side covering part 2 and the palm side covering part 5, which contain the rigid materials 11 and 13. The wrist motion is limited to a maximum of 90 degrees, as shown in FIGS. 7(a) to (c), and the practice of high back stroke motion, which is a highly difficult stroke technique, can be efficiently and selectively strengthened.
また、本発明の練習用手首固定装具１を装着したストローク練習では、手首が固定されているので、シャトルのインパクトポイントが一定となることから、適切なミートポイントを習得することも可能となる。 Furthermore, in stroke practice wearing the training wrist fixing device 1 of the present invention, since the wrist is fixed, the impact point of the shuttlecock remains constant, so it is also possible to learn an appropriate meet point.
本発明の練習用手首固定装具１を装着したストローク練習と手首関節の不要な動きを制限したストローク技術とその習得方法（Kawakita Method）による、高難度技術であるハイバックハンドストローク習得状況について実施実証した。 We conducted a demonstration of stroke practice using the wrist immobilization training device 1 of the present invention, and demonstrated the progress of learning a high backhand stroke, a highly difficult technique, using a stroke technique that limits unnecessary movement of the wrist joint and a method for learning it (Kawakita Method).
被験者５０人の技術レベル実技を通して精査し、初級、中級、上級に分類し、ハイバックストローク技術習得状況を検証したところ下記表１のようになった。 The technical level of 50 subjects was examined through practical skill, and the subjects were categorized into beginner, intermediate, and advanced, and the learning status of high back stroke technique was verified, as shown in Table 1 below.
上記表１によると、上級レベルが８０％の習得率となっているが、これは上級レベルになって初めて習得できる技術であると推測れる結果となっている。 According to Table 1 above, the acquisition rate is 80% at the advanced level, which suggests that this is a skill that can only be acquired at the advanced level.
次に、上記表１の被験者、初級、中級、上級、それぞれ同時に練習用手首関節固定具１を非装着の場合と装着した場合の、ハイバックストローク技術習得時の習得差について比較した。 Next, a comparison was made regarding the difference in acquisition of the high back stroke technique between the subjects shown in Table 1, beginner, intermediate, and advanced, respectively, when they were not wearing the training wrist joint fixation device 1 and when they were wearing it at the same time.
まず、それぞれの被験者へ手首関節の不要な動きを制限したストローク技術とその習得方法（Kawakita Method）によるハイバックストローク技術習得方法についての説明を行った。 First, we explained to each subject the stroke technique that limits unnecessary movements of the wrist joint and how to acquire the high back stroke technique using the Kawakita Method.
被験者は、本発明の練習用手首関節固定具１を利き手に装着すると、被験者の手首の背屈角度が少なくとも７０度から最大９０度に固定され、撓屈方向と尺屈方向へ手首の動きが制限されることを確認した。 The subject confirmed that when the wrist joint immobilization device 1 for training of the present invention was worn on the dominant hand, the dorsiflexion angle of the subject's wrist was fixed at at least 70 degrees and at a maximum of 90 degrees, and wrist movement in the flexion and ulnar flexion directions was restricted.
被験者が、本発明の練習用手首関節固定具１を利き手に装着した状態でラケットを持ち、図７（ａ）のように撓屈側へ手首を移動させ準備し、ハイバックストローク打点位置へ投げられたシャトルコックを、図７（ｂ）のように尺屈方向へ手首を移動させた瞬間にインパクトを迎え、図７（ｃ）の位置に至るフォロースルー状態になるまでの一連の動作ができていることを確認してここでのハイバックストロークを習得したとした。 The subject holds a racket while wearing the wrist joint fixation device 1 for practice of the present invention on his/her dominant hand, moves his/her wrist to the flexion side to prepare as shown in Figure 7(a), and when the shuttlecock is thrown to the high back stroke impact point, the subject makes impact at the moment the wrist moves in the ulnar flexion direction as shown in Figure 7(b), and confirms that the subject has mastered the high back stroke by confirming that the subject has mastered the series of movements up to the follow-through state in the position shown in Figure 7(c).
すなわち、被験者が本発明の練習用手首関節固定具１を利き手に装着して、ストローク練習を行うと、手首関節が固定され、その特定の動作について選択的強化が図れる。 That is, when a subject wears the training wrist joint fixing device 1 of the present invention on his/her dominant hand and practices strokes, the wrist joint is fixed and that specific motion can be selectively strengthened.
検証実験に際して、被験者は、練習用手首関節固定具１を非装着の場合でも、手首関節の不要な動きを制限したストローク技術とその習得方法（Kawakita Method）によるハイバックストローク動作を行うものとした。 During the verification experiment, the subjects performed high-back stroke movements using stroke techniques that limit unnecessary wrist joint movements and the method for learning them (Kawakita Method) even when not wearing the practice wrist joint fixation device 1.
被験者は、最初に非装着でストローク動作を行い、次に装着してストローク動作を行った。検証実験時間はそれぞれ１０分とした。 The subjects first performed strokes without wearing the device, and then performed strokes while wearing the device. The verification experiment lasted 10 minutes each.
上記表２は、手首関節の不要な動きを制限したストローク技術とその習得方法（Kawakita Method）に基づき、非装着・装着それぞれにおいて、ハイバックストローク習得の達成度を率で示したもの。 Table 2 above shows the percentage of achievement in mastering the high back stroke with and without the high back, based on the stroke technique that limits unnecessary movement of the wrist joint and the method for mastering it (Kawakita Method).
上記表２によると、本発明の手首関節固定具１を利き手に装着時、特に初級レベルにおいての習得率の上昇は著しく、中級レベルであっても８０％が習得出来ていることがわかる。なお、非装着の場合でもそれぞれの技術レベルで１０％の習得率向上が見られた。 From Table 2 above, when the wrist joint fixation device 1 of the present invention is worn on the dominant hand, the increase in the learning rate is particularly remarkable at the beginner level, and even at the intermediate level, 80% of participants are able to learn. Even when not wearing the device, a 10% increase in the learning rate was observed at each skill level.
上記表１と上記表２から、手首関節の不要な動きを制限したストローク技術とその習得方法（Kawakita Method）説明し、その後本発明の練習用手首関節装具１を装着したストローク練習を行った場合、従来上級レベルになってからしか習得できないとされていた、高難度ストローク技術の一つであるハイバックストロークを早期に習得可能になったといえる。 From Table 1 and Table 2 above, we will explain the stroke technique that limits unnecessary movements of the wrist joint and how to learn it (Kawakita Method), and then perform stroke practice wearing the training wrist joint brace 1 of the present invention. It can be said that it is now possible to learn the high back stroke, which is one of the highly difficult stroke techniques, which was previously thought to be learned only at an advanced level.
上記図３の剛性材１０及び１３を、手首の背屈角度を少なくとも１５度から最大３５度に制限すれば、サイドバックハンドストロークに必要な手首関節の運動を早期に習慣づけることを可能とする。 By using the rigid members 10 and 13 in Figure 3 to limit the wrist dorsiflexion angle to at least 15 degrees and a maximum of 35 degrees, it becomes possible to quickly develop a habit of the wrist joint movement required for a side backhand stroke.
上記図８から図１４の本発明の第二形態である練習用手首関節固定具２０では、利き手の甲側の手関節部分から中手骨部分を覆うように装着される甲側被覆部２１と少なくとも掌側の手首関節部分を覆うように被着される掌側被覆部２４とを備え、甲側被覆部２１の下端突出部２４に、手首に巻きつけるベルト部２２からなり、上記甲側被覆部２１と掌側被覆部２４に手首の背屈の角度を固定するため適宜の剛性材１３と剛性材１１を内包し、上記甲側被覆部２１の撓骨側に、手首を撓屈側への動きを制限する適宜の剛性材１２が内包されていて、バドミントンストローク技術の一つである、フォアハンドストローク動作の練習を効率よく選択的強化が図れる。 The wrist joint fixation device for practice 20, which is the second embodiment of the present invention shown in Figures 8 to 14, is equipped with a back side covering part 21 that is attached to cover the wrist joint part to the metacarpal part on the back side of the dominant hand, and a palm side covering part 24 that is attached to cover at least the wrist joint part on the palm side. The lower end protrusion 24 of the back side covering part 21 is made of a belt part 22 that is wrapped around the wrist. The back side covering part 21 and the palm side covering part 24 contain appropriate rigid materials 13 and 11 to fix the angle of dorsiflexion of the wrist, and the radial side of the back side covering part 21 contains appropriate rigid material 12 to limit the movement of the wrist to the radial side, and the practice of the forehand stroke movement, which is one of the badminton stroke techniques, can be efficiently and selectively strengthened.
剛性材１２は、厚さ２ｍｍのアクリル製プレート又は塩化ビニル製プレート等の硬質プラスチック製プレートで、手首の撓屈を制限するため少なくとも、手首の撓骨手根関節を亘って掌の第１指側の側部に延在し得るよう形成及び配置されている。 The rigid member 12 is a hard plastic plate such as an acrylic plate or a vinyl chloride plate with a thickness of 2 mm, and extends at least across the radial carpal joint of the wrist to limit the flexion of the wrist. It is formed and arranged so that it can extend to the side of the side.
甲側被覆部２１の下部突出部３０の裏面と掌側被覆部３１表面に互いに係止しうる係止手段２７及び２５が設けられている。 The back surface of the lower protrusion 30 of the back side covering part 21 and the surface of the palm side covering part 31 are provided with locking means 27 and 25 that can lock together.
手首に巻きつけるベルト部２２は、手首に巻きつけたときに重なり合う表面側２６ａと裏面側２６ｂに面ファスナーの雌面と雄面が配されたナイロン繊維製の非伸縮性ベルトで形成されており、その片端部が甲側被覆部２１の下部突出部２３の表面に取り付けられたプラスチック製の角形リングからなるベルト引締め用バックル３０に固定され、自由端となる他端側を手首の先端部に巻き付けてからバックル３０に差し通して折り返し、その折り返した他端側を引っ張って巻締めた状態として表面側２２ａと裏面側２２ｂを面ファスナーで接着することにより、甲側被覆部２１を手首に締め止めるようになっている。 The belt portion 22 to be wrapped around the wrist is formed of a non-stretchable belt made of nylon fiber, with female and male surfaces of a hook-and-loop fastener arranged on the front side 26a and back side 26b, which overlap when wrapped around the wrist. , one end of which is fixed to a belt tightening buckle 30 made of a square plastic ring attached to the surface of the lower protrusion 23 of the instep covering part 21, and the other free end is attached to the tip of the wrist. After wrapping it, insert it through the buckle 30, fold it back, pull the other folded end side to tighten it, and then glue the front side 22a and the back side 22b with a hook-and-loop fastener, thereby tightening the instep side covering part 21 around the wrist. It's supposed to stop.
甲側被覆部２１は、ネオプレンゴムなどの衝撃吸収材料からなり、表面及び裏面の生地はナイロン製からなる。 The instep side covering portion 21 is made of a shock absorbing material such as neoprene rubber, and the front and back fabrics are made of nylon.
以上のように構成された練習用手首固定装具２０を利き手に装着すると、剛性材１１及び剛性材１３を内包した、甲側被覆部２１と掌側被覆部２４によって、手首の背屈が少なくとも７０度から最大９０度に制限され、図１４（ａ）から（ｃ）のような手首の動作となり、バドミントンストローク技術の一つである、フォアハンドストローク動作の練習を効率よく選択的強化が図れる When the training wrist fixing brace 20 configured as described above is worn on the dominant hand, the back side covering part 21 and the palm side covering part 24, which include the rigid material 11 and the rigid material 13, suppress the dorsiflexion of the wrist by at least 70 degrees. The wrist movement is limited to a maximum of 90 degrees, as shown in Figures 14 (a) to (c), and it is possible to efficiently and selectively strengthen the practice of forehand stroke movement, which is one of the badminton stroke techniques.
また、本発明の練習用手首固定装具２０を装着したストローク練習では、手首が固定されているので、シャトルコックのインパクトポイントが一定となることから、適切なミートポイントを習得することも可能となる。 Furthermore, in stroke practice with the training wrist fixing brace 20 of the present invention attached, since the wrist is fixed, the impact point of the shuttlecock remains constant, making it possible to learn an appropriate hit point. .
手首関節固定具の基本構造は多くの関節サポーター製品に見られる巻き付け固定型で説明したが、装着時に各々の目的位置に所望の硬度・角度を有する部分に配置された設計のリストバンド型や手袋型のような円筒形状であっても良い。 The basic structure of the wrist joint immobilizer has been explained as a wrap-around type seen in many joint support products, but it may also be cylindrical, like a wristband or glove, designed to have parts with the desired hardness and angle at each desired position when worn.
上記剛性材１１～１３は本発明主たる目的においては重量的にアクリル製又は塩化ビニル製、若しくはより比重の小さい素材（カーボンなど）からなるプレートが好ましいが、筋力トレーニングの付加的効果を想定し、敢えて比重の大きい素材、例えば、スチール製などの金属プレートを選択することも可能である。 For the primary purpose of the present invention, the rigid materials 11-13 are preferably plates made of acrylic or polyvinyl chloride, or a material with a lower specific gravity (such as carbon), but it is also possible to select a material with a higher specific gravity, such as a metal plate made of steel, in order to achieve the additional effect of strength training.
上記剛性材１１～１３は、軽量性及び生産性の優位性を考慮して、手首関節を所望の角度に固定及び手首関節の動作を所望の方向へ制御できる形状に折り曲げ成形された３枚のプレートからなる構成となっているが、手首関節を所望の角度に固定あるいは手首関節の動作を所望の方向へ制御できれば、他の構成であっても構わない。例えば、剛性材１１、１３のプレートの曲がり部分において、背屈角度を維持しつつも柔軟性をもたらせる構造が考えられる。 The rigid members 11 to 13 are made up of three plates that are bent into a shape that allows the wrist joint to be fixed at a desired angle and the movement of the wrist joint to be controlled in a desired direction, taking into consideration the advantages of light weight and productivity, but other configurations are also acceptable as long as the wrist joint can be fixed at a desired angle or the movement of the wrist joint can be controlled in a desired direction. For example, a structure that provides flexibility while maintaining the dorsiflexion angle at the bent portions of the plates of the rigid members 11 and 13 is conceivable.
生産性、多様性を考慮して、これらの所定位置における硬度や形状の実現に向けて、複数のプレートを採用した構造を紹介したが、手首関節固定具のベース生地の特定位置の材質特性を変えることで実現しても良い。 In consideration of productivity and versatility, we have introduced a structure that uses multiple plates to achieve the desired hardness and shape at these specified positions, but this can also be achieved by changing the material properties of specific positions on the base fabric of the wrist joint fixation device.
本実施例で紹介したプレート材の交換可能な構造（プレートポケット）の場合、手首関節固定具の用途目的に応じて様々なプレート（角度、弾性、比重）を使用することが可能になる。 In the case of the replaceable plate structure (plate pocket) introduced in this embodiment, it becomes possible to use various plates (angles, elasticity, specific gravity) depending on the intended use of the wrist joint fixation device.
また、これらの手首関節の動作を制御して、効率的に特定のストロークの強化を図るための手首関節固定具は、手首関節の個々の動作制御の組み合わせを変えることにより、バドミントンにおける種々のストロークフォーム習得、あるいはバドミントンに限らず、様々な手首関節の動作を必要とする競技においても、同様の効果が期待できる。 Furthermore, wrist joint immobilization devices that control the movements of these wrist joints to efficiently strengthen specific strokes can be expected to have similar effects in acquiring various stroke forms in badminton, or in sports that require various wrist joint movements, not limited to badminton, by changing the combination of individual wrist joint movement controls.
一般的に普及している従来技術の手首関節固定具は、手首関節の怪我のリハビリなどで広く使用されているものであり、スポーツ用手関節固定具の多くはゴルフ練習用で、バドミントンのストローク動作を適切に行うように最適化されていない。 The commonly used conventional wrist joint immobilizers are widely used for rehabilitation of wrist joint injuries, and most of the wrist joint immobilizers for sports are designed for golf practice and are not optimized for proper badminton stroke motion.
バドミントンのストローク技術とその習得方法である（Kawakita Method）の開発により、本発明の練習用手首関節固定具が、バドミントンストローク特有のバックハンドストロークやハイバックストロークについて最適化し、その習得をユーザーに集中的に強化及び習慣づけることを可能とする。 Through the development of badminton stroke techniques and the method for learning them (Kawakita Method), the wrist joint fixation device for practice of the present invention optimizes the backhand stroke and high back stroke that are unique to badminton strokes, allowing the user to intensively strengthen and develop the habit of learning them.
また、本発明の練習用手首関節固定具２０は、バドミントンのストローク技術の一つである、フォアハンドストロークについて最適化し、その習得をユーザーに集中的に強化習慣づけることを可能とする。 The wrist joint training device 20 of the present invention also optimizes the forehand stroke, which is one of the stroke techniques in badminton, and allows the user to develop a concentrated training habit.
上記表１と上記表２にあるテストにおいても、全競技者にとって習得率向上は明らかである。このような本発明の練習用手首関節固定具は、昨今のバドミントン人口の増加と指導者不足を解消できる可能性があり、多くのユーザーに多大なる貢献をもたらすものと期待される。 The improvement in learning rate is clear for all competitors in the tests listed in Tables 1 and 2 above. The wrist joint fixation device for practice of the present invention has the potential to solve the recent increase in the number of badminton players and the shortage of instructors, and is expected to make a great contribution to many users.
