[壓頸] [醫學角度看警暴]

警方一直強調使用「適當武力」制服「暴徒」。當然，邊個係「暴徒」，使用嘅武力又係咪「適當」，大家有目共睹啦。

今日要同大家分析嘅，係呢一個姿勢，我稱之為「壓頸」。千祈唔好以為呢個係「適當」武力，因為壓頸嘅後遺症隨時可以致命。

首先，「壓頸」可以導致頸椎過伸 (hyperextension)。頸椎之間嘅連繫，本身就比其他脊椎鬆動；要使頸椎移位 (dislocation)，需要嘅力度一啲都唔多。咁樣「壓頸」、將成個身體嘅重量施於頸部，極有可能將頸椎後部嘅骨頭壓至骨折；而頸椎前方嘅結構，亦可以因為承受唔住張力而斷裂。其他嘅病狀（例如椎間盤損壞）亦會發生。如果壓住第 1 同第 2 頸椎體，更有機會引致絞死者骨折 (Hangman’s fracture)，存活率極低。

另外，如果力度夠大，頸椎係可以骨折。咁樣嘅後果更大：骨折部分會壓住脊髓，使頸部以下失去感覺同活動能力。更大嘅問題在於，如果損傷發生喺第 5 頸椎體或以上，就會影響控制橫隔膜活動嘅膈神經 (phrenic nerve)，導致呼吸衰竭，繼而死亡。

喺頸部創傷之後，亦多見頸椎椎間盤突出 (cervical disc herniation) ，導致四肢疼痛、無感，而且失去反射能力，需要手術治療。

唔知各位「執法者」喺「壓頸」之前，有冇用過 0.01 秒去學以上知識呢？

[Pressurising the neck] [Analysing police brutality from a medical aspect]

The HKPF had always claimed that they used “suitable force” to put “rioters” under control. Of course, who is the actual “rioter” and whether the force used is of “suitable compatibility” is yet for us to see and judge.

Today the focus is about this particular position - what I call “pressurising the neck” position that the HKPF used frequently. Never categorise this as “suitable” force - it brings severe and even fatal complications and harms.

First, severe hyperextension of the neck can cause dislocation of cervical vertebral arches, as the cervical vertebral arches are less tightly interlocked than other vertebrae. Such dislocation is easily attainable with less force than required. With the whole body sitting on the protestor, cervical fracture can also occur, severing posterior bony structures. Anterior structure (such as the anterior longitudinal ligament) an also get torn and injured due to tension. Other clinical entities like cervical disc damage can also occur. Specifically, compression of C1 and C2 vertebral bodies may lead to Hangman’s fracture, which has a very low survival rate.

Also, if the force is large enough, the cervical vertebral bodies can fracture. This brings along a grave problem: compression of the cervical spinal cord by the vertebral debris can lead to anaesthesia and paresis from the neck down. If the damage is above the C5 body, the phrenic nerve that controls the diaphragm is affected, leading to respiratory failure which is fatal.

Moreover, cervical disc herniation is often observed after trauma to the neck, leading to quadriplegia, quadrianaesthesia and loss of reflexes. Treatment of this condition is often surgical.

I often wonder if these “law enforcers” ever learn about these potential harms of “pressurising the neck” before sitting on the neck of a protestor.

小編最近常常腰酸背痛🤕，前往中醫求診時，被醫生點出我跟椅子黏太久!
因為最近迷上看韓劇，常常一集接一集的續下去😍
不知不覺就坐在椅子上好幾個小時😜，難怪覺得下背不舒服🤔
👨‍⚕️醫生提醒我，長期久坐容易導致頸椎受損，心腦血管疾病增加，女性還容易得婦科疾病，男性容易得前列腺疾病影響性功能，除了這些，久坐還有很多可怕的危害，像是心臟病、高血壓、膽固醇升高、腰部脂肪堆積、肥胖症、肌肉僵硬、便秘、痔瘡、頸椎病……等等疾病!
到底我們要怎麼預防久坐帶來的危害？
醫生建議我們，每當久坐時間差不多90分鐘，就該起身動一動，伸展腿部。
坐立的時候要坐姿挺拔，不要蹺二郎腿，那會對腰椎產生更大的作用力，會使腰椎和腰部肌肉出現問題。
建議平常加強鍛鍊梨狀肌，減少因久坐造成的骨盆移位所帶來的下背痛或是其他久坐的後遺症!
但到底要如何鍛練自己的梨狀肌呢？
如何輕鬆的簡單的鍛鍊梨狀肌，嘉禾姐將在3/9(一)與大家分享!

忍咗咁耐...我決定唔再啞忍！哈哈...講緊嘅係...寒背問題！

寒背對我最大嘅困擾，就係外觀上唔好睇，特別係影相/拍片好多時都不自覺地彎起咗，容易比人一種好攰同唔精神嘅感覺，以前試過買嗰啲寒背矯正器著，又試過晚晚靠埋牆15分鐘，但全部都做做下冇咗件事...

今次上去忠醫到啪一啪，即刻成個人直返哂，唔洗用力都挺直咗?可以挺起胸膛做人喇～

另外仲即場試埋美顏針灸，塊面即時去水腫同緊緻咗??‍♀️

如果你都有任何身體上嘅問題，想搵醫師睇下，咁就唔好等唔好忍喇！搵忠醫約時間喇！
