Description

【０００１】
【発明の属する技術分野】
本発明は、足首部用粘着部材及びその使用方法に関する。詳しくは、医療、スポーツや整体等の分野において、足首関節等を固定等するために用いられる足首部用粘着部材及びその使用方法に関する。
【０００２】
【従来の技術】
足首は全身を支えて体重がかかる部位であり、また、スポーツや日常生活等の動作において捻挫等が発生しやすい部位である。足首は歩行動作に深く関与しているため、足首に痛みが生じると日常の動作が困難になる。そのため、足首に生じる痛みを軽減する対策が強く求められており、例えば、足首関節等を固定する処置がとられる。
専門知識を要せずに足首関節等を固定するための方法として、足首にサポータを装着する方法があるが（例えば、特許文献１参照）、このサポータは極厚に形成された脛当てパッド等を有していて装着太りするので、装着した状態で靴等を履くことはできず、日常動作に不都合があった。また、足首に巻き締めるアンカーストラップと、８の字状に足の甲及び足底を巻き締めるフィギュアエイトストラップと、内果から足底を回り外果を通って巻き締めるスターアップストラップとを備えた、伸縮性のテープ状体からなる足関節サポータがあるが（例えば、特許文献２参照）、装着した後、時間の経過につれて緩みが生じ、十分な足首関節等の固定ができなかった。
足首の痛みを軽減させるために粘着テープを用いて足首関節を固定等すること（テーピング）は、スポーツや医療の分野において従来から行われている処置方法である。適切なテーピングが施されれば、足首を十分に固定して痛みを軽減することができ、かつ、足首等の運動能力を低下させることもないが、適切なテーピングを行うためには専門の知識が必要とされるため手軽に行うことができない、という欠点があった。また、支持、固定力を強化するために、粘着テープを足首に回旋状に重ねて巻きつけるテーピングが行われると、締め付け過ぎによる局部の循環障害や神経障害が生じやすい、という問題があった。

【０００９】
本発明の第二の実施形態に係るテーピング方法は、本発明の第二の実施形態に係る足首部用粘着部材を用い、上記第一の実施形態に係るテーピング方法を行った後、更に、補助用粘着部材の一方の端部を足首部の外側踝を覆うように第二テープ部の上に重ねて貼着し、次いで、他方の端部を足首部の内側踝を覆うように、他方の第二テープ部の上に重ねて貼着することを特徴とする。
【００１０】
【発明の実施の形態】
以下、本発明の実施形態について、図面を参照しながら詳細に説明する。なお、同一の構成要素には同一の参照番号を付して、説明を省略する。
図１は、本発明の第１の実施形態に係る足首部用粘着部材を示す図であり、図１の（ａ）は平面図であり、図１の（ｂ）は正面図である。ここではＨ字型粘着部材のみからなる足首部用粘着部材について説明する。
【００１１】
図１の（ａ）において、Ｈ字型粘着部材Ａは、外形がほぼ矩形状であり、ほぼ中央に足の踵底面に貼着するための底部１を有し、その左側と右側には、それぞれ足首側面及び足首背面に貼着するためのテープ状体１７、１７’を有する。右側及び左側それぞれのテープ状体には、矩形状短辺側から底部１まで達する切込み６、６’が形成されており、右側の第一テープ体と第二テープ体、及び、左側の第一テープ体と第二テープ体に切断されている。また、第一テープ体及び第二テープ体の先端は舌状に形成されている。すなわち、右側の第一テープ体は、第一テープ部２と第一先端部３、右側の第二テープ体は、第二テープ部４と第二先端部５を有し、左側の第一テープ体は、第一テープ部２’と第一先端部３’、第二テープ体は、第二テープ部４’と第二先端部５’を有する。本発明において、舌状とは矩形状の角部が切断されたような形状を意味し、例えば、曲線に類するような多角形状、半円形状、楕円形状、Ｒ字状曲線等も含むものとする。先端部が角を有する矩形状であると、既に貼着されている粘着部材の上（自背面を含む）に重ね貼りをした際に剥がれやすくなるが、先端部を舌状に形成することによって、重ね貼りしても剥がれにくくなる。切込み６、６’の位置は、例えば、第一テープ部２の幅（Ｗ１１）と第二テープ部４の幅（Ｗ１２）の割合が、Ｗ１１：Ｗ１２＝５：５〜５：３の範囲内であることが好ましい。また、左側の切込み６’の位置と右側の切込み６の位置は同一でも異なっていてもよいが、それぞれが上記範囲内であることが好ましい。
底部１は、一方の端辺、ここでは第二テープ側の端辺が凹形状辺７を形成している。凹形状辺７の形状は、足の踵の端を底部１から少々はみ出させることができるような形状であることが好ましい。
【００１２】
本発明の足首部用粘着部材の層構成については後述するが、使用時まで粘着層へ埃等が付着することを防ぎ、粘着層を保護するために、粘着層の上には剥離ライナーが積層されている。この剥離ライナーには数箇所背割りが施されている。例えば、底部１と、右側の第一テープ部２及び第二テープ部４との境界部分８、及び、同様に左側の境界部分８’に背割りが施され、右側の第一テープ部２と第一先端部３との境界部分１０、同様に左側の第一テープ部２’と第一先端部３’との境界部分９、及び、右側の第二テープ部４と第二先端部５との境界部分１２、同様に左側の第二テープ部４’と第二先端部５’との境界部分１１に背割りが施されている。図１に示すＨ字型粘着部材では、背割りされた各パーツの剥離ライナーに数字（▲１▼、▲２▼等）が印刷等されている。これは数字に限定されるものではないが、例えば、テーピングを容易にするために、テーピング順序を示すような文字（数字を含む）、挿絵等の画像が何らかの方法で示されていることが好ましい。
【００１３】
図１に示すほぼ矩形状のＨ字型粘着部材は、矩形状の短辺の長さ（Ｗ１０）が５０ｍｍ〜１５０ｍｍであり、長辺の長さ（Ｌ１０）が３００ｍｍ〜６００ｍｍであることが好ましく、かかる範囲内で、体型、足型等を考慮して適宜設計されることが好ましい。また、切込み６、６’の長さは１５０ｍｍ〜２５０ｍｍであることが好ましく、この長さ及び底部の大きさや形状等も、体型、足型等を考慮して適宜設計されることが好ましい。
【００１４】
図１の（ｂ）に足首部用粘着部材Ａの層構成を例示する。図１の（ｂ）において、足首部用粘着部材Ａは、基材１４と粘着層１５と剥離ライナー１６とからなる。剥離ライナー１６は無くても良いが、使用時まで粘着層１５を汚染から防ぎ、粘着力を保護するためには、粘着層１５の上に剥離ライナー１６を積層することが好ましい。
図１の（ｂ）において、剥離ライナー１６には各パーツの境界部分（８、８’、１１、１２）に背割りが施されており、各パーツを覆う剥離ライナーの各々には、数字（▲１▼、▲２▼等）が印刷された印刷部１３が形成されている。
この剥離ライナーは、一般的に皮膚へ貼付する粘着テープ等に用いられるものを使用することができる。具体的には、上質紙、グラシン紙、パーチメント紙等の表面に、シリコーン等の剥離性能を有する剥離剤をコーティングしたものや、上質紙にレジンをアンカーコートしたもの又はポリエチレンをラミネートしたもの等の表面にシリコーン等の剥離性能を有する剥離剤をコーティングしたもの等を使用することができる。
【００１５】
本発明の足首部用粘着部材は適度なキックバック性を有することが好ましい。したがって、本発明の足首部用粘着部材を構成する基材は、２０％伸張時における引張応力が１０Ｎ／１９ｍｍ幅以下であることが好ましく、足首関節等の固定性の観点から９Ｎ／１９ｍｍ幅以下であることが更に好ましい。また、基材は、８０％伸張時におけるヒステリシスが８５％以上であることが好ましく、８０％伸張時における引張応力が１５Ｎ／１９ｍｍ幅以上であることが好ましい。足首関節等の負担をより軽減するためには、８０％伸張時におけるヒステリシスが８８％以上であることがより好ましく、８０％伸張時における引張応力が１６Ｎ／１９ｍｍ幅以上であることがより好ましい。このような特性を有する基材を含む足首用粘着部材は、足首関節等への追従性と固定性を実現することができる。
ここで、８０％伸張時のヒステリシスとは、足首部用粘着部材を最大伸びの８０％まで伸ばした時の復元性を示す指標である。また、２０％伸張時における引張応力とは、所定形状の試料片を、所定速度で２０％伸張するまで引っ張った時の引張強度をいい、８０％伸張時における引張応力とは、所定形状の試料片を、所定速度で８０％伸張するまで引っ張った時の引張強度をいう。
【００１６】
基材１４は、足首関節等を固定できるような適度な伸張度を有することが好ましく、例えば、ナイロン、ポリエステル、ポリウレタン、レーヨン、ポリプロピレン、ポリエチレン、綿等からなる不織布、織布、強撚布、縦糸に伸縮糸を用いたタテ伸び布、縦糸および横糸に伸縮糸を用いた伸縮布等が挙げられる。本発明においては、上記特性を考慮すると、伸縮性を有する編布（以下、「伸縮性編布」という）を用いることが好ましく、例えば、ナイロン、ポリエステル等の繊維に特殊加工を施すことにより伸縮性を持たせたストレッチヤーンやポリウレタン系弾性糸等のように伸縮性の大きい合繊糸を単独で編成した編み物地、若しくは、このような合繊糸とポリエステル繊維や綿等のように伸縮性の小さい繊維とを混合して編成した編布、スパンボンド不織布に、ポリウレタン等の伸縮糸を編み込んだ編み物地等を用いることができる。なお、編成方法としては、トリコット編、ラッシェル編、ミラニーズ編を含む経（タテ）メリヤス及び、平型編、円形編を含む緯（ヨコ）メリヤスのいずれを用いても良い。このうち、タテメリヤスは、裁断してもほつれが生じないので、より好ましい。また、合繊糸の太さは、４０〜１６０デニール程度であることが好ましい。
【００１７】
基材１４の厚さは、基材の材料特性等によって適宜決定されることが好ましいが、皮膚への追従性を考慮すると０．２〜１．０ｍｍが好ましく、さらに好ましくは０．３〜０．８ｍｍである。
【００１８】
基材１４は、その外表面（図１（ｂ）においては、基材１４の下面）にポリウレタン層が設けられていてもよい。基材１４の外表面をポリウレタン層で被覆することにより、透湿性及び防水性を付与することができる。
ポリウレタン層は、エーテル系ウレタン、エステル系ウレタン等の公知のウレタンから形成される。本発明においては、ポリウレタン層としてポリウレタンフィルムを用いることができる。ポリウレタン層１４の厚さは、５μｍ以上、３０μｍ未満であることが好ましい。ポリウレタン層の厚さが５μｍ以上であれば、例えば伸縮性編布等の基材表面の凹凸を十分にコートすることができるのでピンホールが生じることがなく、ポリウレタン層の厚さが３０μｍ未満であれば、十分な透湿性を保持することができる。
例えば表面に凹凸がある基材の自背面に重ねて貼着すると、重ねて貼着した粘着部材の端がめくれることがあるが、凹凸面をポリウレタン層で被覆することにより、自背面への接着性を向上させることができる。また、防水性に乏しい基材では、雨天時に使用して水濡したりすると貼着した部分が剥がれることがあるが、ポリウレタン層を設けることによって防水性を付与することができる。さらにまた、ポリウレタン層の厚さを調節することにより、キックバック性の程度を調節することができる。
【００１９】
粘着層１５は、貼着した皮膚に追従できる程度の柔軟性や粘弾性を有し、皮膚に対して刺激の少ない粘着剤を用いて形成することが好ましく、一般的なテーピング用粘着テープの分野等で周知、あるいは実用されている種々の粘着剤を使用することができる。具体的には、アクリル系粘着剤、ゴム系粘着剤、合成ゴム系粘着剤、ビニルエーテル系粘着剤、シリコーン系粘着剤、ゲル系粘着剤を用いることができるが、皮膚刺激性等を考慮すると、アクリル系粘着剤もしくはゲル系粘着剤を用いることが好ましい。例えば、油性ゲル粘着剤は、接着力は比較的低いが、皮膚との密着性に優れ、テーピング等の用途には充分であり、剥離する際には皮膚表面の角質を傷つけることがないため、好適に使用することができる。なお、ゲル系粘着剤については、公表特許公報２０００−５１３２８７号を参照されたい。
【００２０】
粘着層１５は、基材１４の片面全面に設けてもよいが、部分的に設けてもよい。基材１４の基材面上に部分的に設ける場合には、粘着層をドット状または条状に形成することができ、粘着層が形成されていない領域が通気路としても機能するので、通気性や透湿性を向上させることができ、発汗によるムレやカブレ等を予防することができる。条状の形状としては、直線状、波状等が挙げられる。一般的には条間空間の断面積の経時的な変化が少ない波状とすることが好ましいが、使用する粘着剤の特性等によって適宜決定することが好ましい。また、粘着層を基材面上に部分的に設ける場合には、条間に通気路として機能する空間が確保されるように、ドットの大きさや配置、条間空間の大きさ等を適宜設計することが好ましい。
所望の領域に粘着剤を塗布する場合には、剥離ライナー上に、例えば、櫛形状の型を用いて塗工中にその櫛を固定したり、振幅移動させたりして、所望のスジ状又はウエイブ状等の形状を有する粘着層を剥離ライナー上に形成し、これを基材１４の面上に転写すればよい。
【００２１】
粘着層１５の厚さは、使用される粘着剤の種類、特性等によって適宜決定されることが好ましいが、例えば、２０〜１２０μｍであることが好ましく、４０〜１００μｍであることが更に好ましい。
【００２２】
足首部用粘着部材には、本発明の効果を阻害しない範囲内であれば、必要に応じて穿孔を施してもかまわない。
【００２３】
次に、Ｈ字型の粘着部材の他に更に補助用粘着部材を独立部材として有する足首部用粘着部材について説明する。図２に本発明の第２の実施形態に係る足首部用粘着部材を示す。
ここで、図２の（ａ）は、図１の（ａ）に示したＨ字型粘着部材Ａと同一である。図２の（ｂ）に示す補助用粘着部材Ｂは、テープ部２１と、その両端部に右端部２２と左端部２２’とを有する構成である。右端部２２及び左端部２２’は舌状に形成されており、角が落とされた形状である。端部を舌状に形成することにより、粘着部材の上に重ね貼りしても剥がれにくくなる。このように、補助用粘着部材Ｂは、ほぼ矩形状の外形を有し、角部がＲ字状の曲線で構成されている。この矩形状の短辺の長さ（Ｗ２０）は５０ｍｍ〜１００ｍｍであり、長辺の長さ（Ｌ２０）は１００ｍｍ〜３５０ｍｍであることが好ましい。ただし、体型、足型等を考慮して、上記範囲内で適宜設計されることが好ましい。
図２の（ｂ）に示す補助用粘着部材の層構成は、図２の（ａ）の層構成と同一であり、すなわち、図１の（ｂ）の層構成と同一で、基材の上に粘着層を有し、粘着層の上には剥離ライナーが積層されている。粘着層を覆っている剥離ライナーは、テープ部２１と右端部２２の境界部２４、及び、テープ部２１と左端部２２’の境界部２４’に背割りが施されている。また、図１（ａ）と同様に、背割りされた剥離ライナーには、各パーツ毎に数字（▲６▼、▲７▼等）が印刷等されている。補助用粘着部材の剥離ライナーに印刷等される数字は、図２（ａ）からの連続番号等であってもよい。
【００２４】
本発明の足首部用粘着部材を用いてテーピングを行う方法の一例として、図２に示すＨ字型粘着部材Ａと補助用粘着部材Ｂとを有する足首部用粘着部材を、足首部に適用した例を以下に説明する。本発明においてテーピングとは、粘着テープ等を用いて関節部、筋肉、腱等の施部を固定することであり、この施部を支持、補正、補強等することにより、痛みを軽減したり、治療を促進したりする効果がある。
【００２５】
図３〜図６は、本発明の第２の実施形態に係る足首部用粘着部材を用いて足首関節等を固定する方法を説明する図であり、図３〜図５はＨ字型粘着部材Ｂを貼着する方法（以下、「方法Ａ」と称すこともある）を示し、図６は補助用粘着部材Ｂをさらに貼着する方法（以下、「方法Ｂ」と称すこともある）を示す。したがって、図１に示すＨ字型粘着部材のみからなる足首部用粘着部材を用いてテーピングを行う場合には、以下に示す使用方法において、補助用粘着部材Ｂを適用する前までの前半の使用方法（方法Ａ）をそのまま適用することができる。
図３の（ａ）において、Ｈ字型粘着部材Ａを、例えば足乗せ台等のように貼着作業が行い易い台の上に、剥離ライナーが上に向くように置く。底部１の剥離ライナー（表示▲１▼）を除去した後、底部１の凹形状辺７に踵の後ろがわずかに出るように、踵底面を底部の粘着層の上に乗せて貼着する（図３の（ｂ）参照）。足首部の外側に貼着すべき第一テープ部２の剥離ライナー（表示▲２▼）を除去し、第一先端部３を手で持って第一テープ部を伸張させながら足首関節の外側踝を覆うように、踵から膝関節方向へ向けて貼着した後、第一先端部３の剥離ライナー（表示▲３▼）を除去してから貼着する（図３の（ｃ）参照）。続いて、図４の（ａ）に示すように、足首部の内側に貼着すべき第一テープ部２’の剥離ライナー（表示▲２▼’）を除去した後、内側の踝を覆うように第一テープ部２’を真上方向に引張って伸張させながら貼着し、第一先端部３’の剥離ライナー（表示▲３▼’）を除去してから先端部を貼着する。これが、いわゆる「スターアップ」に相当するものであり、距骨、踵骨の内反を抑制、制限することができる。次に、図４の（ｂ）及び（ｃ）に示すように、足首部の外側に位置する第二テープ部４の剥離ライナー（表示▲４▼）を除去してから、第二先端部５を持って第二テープ部を伸張させながら、足首関節の後ろを通って内側の踝の上を覆うように貼着した後、第二先端部５の剥離ライナー（表示▲５▼）を除去して先端部を貼着する。その後、図５の（ａ）及び（ｂ）に示すように、足首関節の内側に位置する第二テープ部４’の剥離ライナー（表示▲４▼’）を除去してから、第二先端部５’を持って第二テープ部を伸張させながら、足首関節の後ろを通って外側の踝の上を覆うように貼着した後、第二先端部５’の剥離ライナー（表示▲５▼’）を除去して端部を貼着する。これが、いわゆる「ヒールロック」に相当するものであり、スターアップのテーピング機能と共に、足関節の内かえしを抑制、制限し、距骨が前方へ移動することを抑制、制限することができる。このように、Ｈ字型粘着部材Ａを足首部に貼着する方法を便宜上、「方法Ａ」と称すことにする。
【００２６】
続いて、補助用粘着部材Ｂの片方の端部２２の剥離ライナー（表示▲７▼）を除去して、足の甲から外側踝を覆うようにＨ字型粘着部材Ａの上に重ねて貼着する。その後、テープ部６の剥離ライナー（表示▲６▼）を除去し、テープ部６を引張って伸ばしながら、足首後ろのアキレス腱を覆うようにテープ部６を貼着する。最後に、残りの端部２２’の剥離ライナー（表示▲７▼’）を除去した後、内側踝を覆い、さらに足の甲までかかるように端部２２’を貼着する（図６の（ａ）及び（ｂ）参照）。これが、いわゆる「ハーフエイト」に相当するものである。このように、Ｈ字型粘着部材Ａを貼着した後、更に補助用粘着部材Ｂも足首部に貼着する方法を便宜上、「方法Ｂ」と称すことにする。
【００２７】
本発明によれば、方法Ａによるテーピングによって、足首関節等を適切に固定することができる。さらに補助用部材を用い、重ねてテーピングすることによって、アキレス腱を保護し、足首部の固定力を強化することができ、さらには、Ｈ字型粘着部材の第一テープ部を固定する役割も果たすことができる。また、必要に応じて、底部に適度に体重をかけながらテーピングを行ってもよい。このようにすれば、運動時に足首関節等に負荷がかかった状態に近い状態でテーピングを行うことになる。
本発明の足首部用粘着部材は剥離ライナーに貼着順序を示す表示がなされているので、この順序に従って貼着すれば、テーピングの専門知識がない人でも、容易に、しかも適切な位置にテーピングすることができる。
【００２８】
【実施例】
以下に本発明の実施例を示し、さらに具体的に説明するが、本発明はこれらに限定されるものではなく、本発明の技術的思想を逸脱しない範囲内で種々の応用が可能である。
【００２９】
実施例１
２−エチルヘキシルアクリレート９０重量部、及び、アクリル酸９重量部の混合物を、不活性ガス雰囲気下で酢酸エチルによって共重合することによりアクリル系粘着剤を得た。このアクリル系粘着剤を、上質紙にポリエチレンをラミネートした面にシリコーン処理を施した剥離ライナーの処理面に、乾燥後の厚さが８０μｍとなるように塗布し、１２０℃で３分間乾燥させて粘着層を形成した。この粘着層の上に、基材として用意したポリエステル７５デニール糸をスムーズ編で伸縮するように編み込んだ、厚さ４５０μｍの伸縮性編布を重ね、貼合せることにより、基材／粘着層／剥離ライナーの層構成を有する積層体を得た。なお、伸縮性編布は、２０％伸張時における引張応力が２．５Ｎ／１９ｍｍ幅であり、８０％伸張時におけるヒステリシスが９２％、引張応力が１９Ｎ／１９ｍｍ幅であった。
得られた積層体に打ち抜き加工を施して、図２に示すような形状のＨ字型粘着部材と補助用粘着部材からなる足首部用粘着部材を得た。ただし、Ｈ字型粘着部材の外形の矩形状は、短辺の長さ（Ｗ１０）が９０ｍｍ、長辺の長さ（Ｌ１０）が４１０ｍｍ、底部の長さが７０ｍｍ、テープ部の長さが１４０ｍｍであり、Ｗ１１：Ｗ１２＝５：４であった。また、補助用粘着部材の長さ（Ｌ２０）が２５０ｍｍ、幅（Ｗ２０）が７０ｍｍであった。また、剥離ライナーには各部の境界部分に背割りが施され、貼付順番を示す連続数字のスタンプが押されてあった。得られた足首部用粘着部材を用い、上記方法Ａに従って、足首部にテーピングを行った。

BACKGROUND OF THE INVENTION
The present invention relates to an ankle adhesive member and a method of using the same. More specifically, the present invention relates to an ankle part pressure-sensitive adhesive member used for fixing an ankle joint and the like in the fields of medical treatment, sports, and body modification, and a method of using the same.
[0002]
[Prior art]
The ankle is a part that supports the whole body and gains weight, and is also a part where sprains and the like are likely to occur in sports, daily activities, and the like. Since the ankle is deeply involved in walking movement, daily movement becomes difficult when pain occurs in the ankle. Therefore, there is a strong demand for measures to reduce pain in the ankle. For example, a measure for fixing an ankle joint or the like is taken.
As a method for fixing an ankle joint or the like without requiring specialized knowledge, there is a method of attaching a supporter to the ankle (see, for example, Patent Document 1). Therefore, it is impossible to wear shoes or the like in a worn state, which is inconvenient for daily operations. In addition, it was equipped with an anchor strap that wraps around the ankle, a figure eight strap that wraps the instep and bottom of the foot in a figure-eight shape, and a star-up strap that wraps around the sole from the inner fruit through the outer fruit. Although there is an ankle joint supporter made of a stretchable tape-like body (see, for example, Patent Document 2), after wearing, loosening occurred over time, and sufficient ankle joint and the like could not be fixed.
Fixing an ankle joint with an adhesive tape (taping) in order to reduce ankle pain is a treatment method conventionally performed in the fields of sports and medicine. If appropriate taping is applied, the ankle can be sufficiently fixed to alleviate pain, and it does not reduce the exercise capacity of the ankle, etc. However, there is a disadvantage that it cannot be easily performed. Further, in order to strengthen the support and fixing force, there has been a problem that local circulatory disturbance and neurological disorder due to excessive tightening are likely to occur when taping is performed in which the adhesive tape is wound around the ankle in a convoluted manner.

Comparative Example 1
Taping was performed by a general method using a normal tape generally known as a sports taping tape. That is, first, an underwrap tape is applied around the ankle. Next, two non-stretchable anchor tapes (38 mm width) are pasted at a position about 5 cm above the ankle. However, the two anchor tapes are shifted by about 1/3 to 1/2, and are wound around. Next, the star-up tape (38 mm width) is attached by pulling up from the position of the inner anchor tape through the inner hook to the position of the outer anchor tape. However, three star-up tapes are attached so as to be shifted by about 1/3 to 1/2. Then, in order to stop the end part of the star-up tape with the anchor tape, two anchor tapes are wound and stuck at a position about 5 cm above the ankle. Next, in order to prevent the ankle from wobbling by applying pressure to the area around the ankle, the figure eight tape starts from the position of the Achilles tendon, passes through the outer heel from here to the back of the foot, passes through the arch, and again Cross over, return to the starting point through the inner heel, and further past the Achilles tendon and wrap around the outer half. Thereafter, heel lock taping is performed. In other words, the elastic twisted tape of the strong twist cloth starts from the back of the foot, passes from behind the heel to the arch through the lower side of the outer heel, and crosses again at the upper. Next, it passes over the outer heel, turns to the heel via the Achilles tendon, passes obliquely through the arch through the lower side of the inner heel, and then turns to the instep. This operation is repeated to continuously wind up to the position of the anchor tape attached above the ankle.
