被人從背後雙手穿過腋下鎖住頸後如何逃脫？

12-29

A在B後方，雙手從B腋下穿過，向上，手掌在B頸後交叉，十指相扣。B被控制時如何脫險？

我個人傾向於這個動作比較危險容易造成比較嚴重的後果

這個問題下有兩個分歧，有的人覺得這技術殺傷力很大，有的人覺得這個技術如同智障。

因為這個技術（Double nelson hold）在普通人的手裡根本毫無威力，但是一個100kg+的摔跤手使用時，足以使對手窒息和頸椎錯位。

所以這招在摔跤、MMA、柔術里都是禁止的。

以上

至於如何脫險，那必須假設對手是誰。如果是體重100kg+的摔跤手比利在gym里的決鬥中將你控制在這個體位，你最好的選擇是投降（？），如果掙扎的話，會增加你頸椎受傷的可能性。

如果對方是鄰居家放假回家的大學生小王，你可以跺他腳面（MMA version），可以背摔，可以用力下墜兩肘暴力解脫，等等等等。

在早先公安部的《擒敵技術教材》里，這招是無解的。

確實，如果二人體能和體格等指標相當的情況下，被控制的一方很難解脫。所以這招是用於突襲控制嫌疑人的，或者是把嫌疑人按倒但對方還在掙扎而你又未攜帶其他警械的情況下，可以用來制服並等待同事支援。

對方特彆強壯的時候不能用，如果用了，對方脖子向後頂手臂向前壓，會讓你交叉扣緊的手指受傷。

體格相當的情況下，也最好不要用，首先是未必能徹底完成（比如偷襲時，對方反應過來後會做出相應的抵抗，你穿過腋下的手臂很難完成在他腦後的交叉握固動作），其次即使完成了，對方會豎直向上舉起手臂（讓你下壓他後頸的時候手臂失去槓桿支點），然後下蹲向前摔你過頂，你的雙手反而不能及時放開。

至不濟，對方也能向兩側伸展手臂然後曲臂，用他的大小臂夾住你的小臂，這樣，你就無法用臂力壓迫他的頸椎（你的小臂被他限制），只能靠腕力。而腕力的力度要對抗頸部的力量，就算有效也不是碾壓式的效果，他完全扛得住。接下來就看你倆的腿腳和腰部抗衡誰能佔上風了。

很多動作是理論家設計出來的，教學痕迹嚴重，實戰意義較差。比較典型的就是那個姓馬的太極拳師說他打敗了搏擊冠軍的例子，那視頻就是教學視頻，二人的動作是設計好來展示三連擊原理的，設計的時候忽視了對方的右手，實戰中，對方不可能讓姓馬的用一秒鐘以上的時間去控制他的左臂而自己的右手一動不動，右手在這一秒鐘里，至少能給老馬腦袋上來兩拳，老馬兩隻手全在用於控制對方左臂，對方右拳襲來，純粹無法招架。如果老馬用左臂去招架，那就等於放棄了使到一半的三連擊，也就是對方破解了他的動作。

樓下巴柔館長伊迪亞特的破解方法是正確的，但也有一點理論性痕迹，因為，對方即使被你用腿絆倒，他的雙臂完全可以不鬆開（摔跤類的比賽，身體倒地不會影響手臂動作，選手在倒地時完全可以保持手臂動作不變，你很少有機會在倒地的瞬間解脫），你跟他同時倒地，不管體位如何，總之他就是控制著你的頭頸和雙臂不放，你也沒法子。至於把腿插到對方雙腿之間再用手抬起對方一條腿，這樣的思路就是明顯的設計感了——視頻里的陪練為了讓館長做到這個動作，並未用力下壓他的頭頸，也沒有控制他大臂的運動範圍，更沒有做出有效的動作來（有效的動作是：雙肘抬起確保對方雙臂不能大範圍活動，肩向後，確保對方軀體緊貼自己的前胸）而在實戰中，館長的手臂無論如何也伸不到腰部以下去的——你的手臂最多是平伸，再往下就做不到了，你的腋窩就是我的支點，你怎麼可能把手往下伸呢，卡得你死死的。實戰（不是比賽，而是街頭糾紛）當中，你敢反抗，我就敢壓斷你的頸椎，一般人在頸椎未斷之前就會因為疼痛和恐懼放棄其他動作，乖乖被控制。

周星馳：「啊，我現在被人家用『納爾遜式鎖』鎖著了，快要受不了了！」

王局長：「納爾遜式鎖太小兒科了，你現在豎起兩隻手指頭，四十五度角往上一插！」

。。。

「怎麼樣，有沒有插到他眼睛啊？」

周星馳：「啊~沒有，只是插到他的鼻孔罷了。」

王局長：「那就挖呀挖呀挖呀，把那個空氣都挖出來！」

。。。

周星馳：「啊，厲害啊，解開了！」

王局長：「哈，那還用說啊，不然我當年怎麼當打電話問功夫的節目主持人啊！龍五呢？」

踩腳（高跟鞋尤其有效）

或者小腿向後踢對方屌（適合高女對付矮男）

首先這個動作的性質是純控制性質的動作。

它不像裸絞，沒有絞殺或者反關節作用，並不會對人體造成傷害。

在實際應用中一般出現在學生之間的打鬧嬉戲中....

所以....

如果真的要認真解鎖的話。

1、就分開雙腿站穩，然後雙手穿過自己的胯下抓住對方一個腳踝或者褲腿，然後提起，同時向後倒。

2、雙手向上伸，然後十字合掌，扣緊，身體下沉，雙肘猛的向下壓，對方就很難繼續保持雙手的扣。

其實，同學玩鬧，撓痒痒就好啦～

有其他答主說這個動作十分危險，在MMA里是禁止使用的，在這裡我找來了UFC的全套規則，這些年來我讀了幾遍了，並沒有看到這個動作被ban了，也不相信這個動作被ban了，畢竟斷頭台這種脊椎毀滅者都沒被ban。

在這裡我把規則放出來。

The Nevada State Athletic Commission currently lists the following as fouls:

Biting

Eye-gouging

Fish-hooking

Groin attacks

Small joint manipulation

Hair pulling

Evolution of the rules

UFC 1 – Although the advertising said There Are No Rules, there were in fact some rules: no biting, no eye-gouging and no groin attacks. Fights ended only in the event of a knockout, submission or the corner throwing in the towel. Despite this, the first match in UFC 1 was won by referee stoppage, even though it was not officially recognized as such at the time.

UFC 2 – Groin attacks were unbanned. Time limits were dropped ending the need for judges. Modifications to the cage were added (the fence became 5 feet tall but would continually grow in height afterwards and the floor became the canvas that is still used today).

UFC 3 – The referee was officially given the authority to stop a fight in case of a fighter being unable to defend himself. A fighter could not kick if he was wearing shoes. This rule would later be discarded, then changed to "no kicking with shoes while on the ground" and then reinstated, before finally being discarded.

UFC 4 – After tournament alternate Steve Jennum won UFC 3 by winning only one bout, alternates (replacements) were required to win a pre-tournament bout to qualify for the role of an alternate.

UFC 5 – The organizers introduced a 30-minute time limit. UFC 5 also saw the first Superfight, a one-off bout between two competitors selected by the organizers with the winner being crowned "Superfight champion" and having the duty of defending his title at the next UFC.

UFC 6 – The referee was given the authority to restart the fight. If two fighters were entangled in a position where there was a lack of action, the referee could stop the fight and restart the competitors on their feet, in their own corner. In UFC 6 they officially adopted the 5-minute extension to the 30-minute rule which had been used in UFC 5.

Ultimate Ultimate 1995 – This event was the first to introduce the no fish-hooking rule and to reinstate judges. Time limits were changed to 15 minutes in the quarter-finals, 18 minutes in the semi-finals and 27 minutes in the finals.

UFC 8 – Time limits changed to 10 minutes in the first two rounds of the tournament, 15 minutes in the tournament final and Superfight. Time limits would continually change in the later UFC events. Fights could now be decided by a judges decision if the fight reached the end of the time limit. The panel was made up of three judges who simply raised a card with the name of the fighter they considered to be the winner. In this fashion, a draw was not possible since the only two possible outcomes of a decision were 3 to 0 or 2 to 1 in favor of the winner.

UFC 9 – To appease local authorities, closed fisted strikes to the head were banned for this event only. The commentators were not aware of this last minute rule that was made to prevent the cancellation of the event due to local political pressures. Referee "Big John" McCarthy made repeated warnings to the fighters to "open the hand" when this rule was violated. However, not one fighter was reprimanded. UFC 9 was also the last UFC event to feature the superfight.

Ultimate Ultimate 1996 – This event was the first to introduce the "no grabbing of the fence" rule.

UFC 12 – The main tournament split into a heavyweight (over 200 lbs.) and lightweight (200 lbs. and under) division; and the eight-man tournament ceased. Fighters now needed to win only two fights to win the competition. The Heavyweight Champion title (and title bouts) was introduced, replacing the Superfight title (albeit matches were still for a time branded as "Superfights").

UFC 14 – The lightweight division was re-branded middleweight. The wearing of padded gloves, weighing 110 to 170 g (4 to 6 ounces), becomes mandatory. Gloves were to be approved by the UFC. Hair-pulling, groin strikes and kicks to a downed opponent became illegal.

UFC 15 – Limits on permissible striking areas were introduced. Headbutts, elbow strikes to the back of the neck and head and small joint manipulation became illegal.

UFC 21 – Five minute rounds were introduced, with preliminary bouts consisting of two rounds, regular non-title bouts at three rounds, and title bouts at five rounds. The "ten-point must system" was introduced for scoring fights (identical to the system widely used in boxing).

UFC 28 – The New Jersey State Athletic Control Board sanctions its first UFC event, using the newly developed Unified Rules of Mixed Martial Arts. Major changes to the UFC"s rules included barring knee strikes to the head of a downed opponent, elbow strikes to the spine and neck and punches to the back of the neck and head. Limits on permissible ring attire, stringent medical requirements, and regulatory oversight were also introduced. A new weight class system was also introduced.[153] This new set of rules is currently the de facto standard for MMA events held in the U.S. and is still in use by the UFC.

UFC 31 – Weight classes are re-aligned to the current standard. Bantamweight moves from 150 to 155 and becomes known as lightweight. Lightweight becomes known as welterweight, middleweight becomes light heavyweight, and a new middleweight class is introduced at 185 pounds. Stools and seconds are first permitted in The Octagon between rounds.

UFC 43 – In the event of a stoppage fights restart in the position the fight was stopped.

UFC 94 – After an incident where Georges St-Pierre was accused of putting vaseline on his back, corner men were disallowed from bringing vaseline into The Octagon. Petroleum jelly may now only be applied by UFC employed cutmen.

UFC 97 – Foot-stomps are banned. (For this event only)

UFC 133 – Speedo style trunks are banned.[154]

UFC 138 – First 5-round non-title main event.[155]

沒成型前手臂放鬆往下蹲，或者沉肘拆開都行，鎖死了除了用爆發力拆手指以外我沒找到解法。

這個技術實戰用的時候可以把對方的後腰拖到自己膝蓋上面造成殺傷，殺傷力並不小。

有些人說這動作好拆那單純只是在成型前。。。

謝邀。

不過居然有人會邀請我回答這個問題…

首先絕不可以嘗試抬頭強制與之對抗，會對頸椎造成極大傷害，有可能骨折或導致椎間盤脫出。

據我所知的做法是，首先一隻手抓住另一隻手手腕，將自己手臂撐起，腋窩夾緊，鎖住對方手腕，在這個姿勢下如果他想保持對你的壓力，他是的手是被卡死的。然後腰背彎曲轉向一側（右側為例），屁股這時候就會挪到他左側，將右腳撤到他背後並微屈雙膝，然後鬆開自己的手，右手越過其腹部，左右手分別抱起左右腳，順勢提起（最好使其臀部過腰）後向下摔倒，你整個人也是重重地砸在他身上的，也就是所謂的寢技。摔倒後拍手挺胯可起，似乎傳統武術里叫「鯉魚打挺」吧…

哎，看不下去一堆玄學答案，這是一個很基礎的技術啊，當年上古格鬥神獸，Bas Rutten就給出過針對頭部從後方被控制時的標準答案

這一招答主@滇池泡說的很好，在不同人手中有著不同的殺傷力。他不是一個控制技術，而是一個殺傷技術（雖然它有很大的控制技術的迷惑表象），所以出現一定要第一時間破解。

當然破解方法也有。

不過Bas給的例子的在裸絞（未完成）時逃脫的，裸絞使用者並未用腿部施加固定。所以柔術愛好者不要誤傷我

方法一：針對個子矮於自己的對手，對手把你往前壓
