📌 When we talk about ACL injuries we often think about excessive knee valgus, which is a false frontal plane biomechanics. But one of the other predisposing factors of ACL injury is attributed to poor landing mechanics. -
⁉️ What is poor landing mechanics? It is stated as “stiff landings” [Leppa ̈nen et al., 2016] [ W.A. Laughlin et al., 2011] , wheres a good landing is stated as “soft landing”
-
🎯 “Stiff landing” means less knee flexion at the time of impact and a greater vertical ground reaction force. So the leg appears more straight and is unable to absorb impact
-
🎯 Study has shown that force exerted on ACL at point of impact decreases by 11% compared to a stiffer landing [Simonsen et al., 2000]. The primary reason is an increase posterior shear force generated by the hamstrings from a greater knee flexion angle
-
🎯 Less force is exerted on ACL means a lower chance of knee injury 💯 Strengthening of the hamstrings, especially the eccentric part can help you stay injury-free -

💥 十字韌帶傷後著地評估
“著地緩衝技巧 “
-
❤️標記你十字韌帶受傷的好朋友 分享到你的限時動態
-
📌 我們在討論膝蓋受傷，或是前十字韌帶損傷，都會提到膝蓋外八跟膝蓋受傷有很大的關係。外八是膝關節在額狀面呈現外翻的排列。人體分為三個動作平面，除了額狀面，還有冠狀面跟矢狀面。在矢狀面，常會導致十字韌帶受傷的原因，則是因為著地的技巧
-
⁉️ 什麼是好的著地技巧？什麼是不好的著地技巧? 不好的著地技巧又被稱為「僵硬的著地」 [Leppa ̈nen et al., 2016] [ W.A. Laughlin et al., 2011]，好的著地技巧又被稱為「緩衝著地」
-
🎯 「僵硬的著地」指的是從跳起來到著地時，膝關節彎曲的角度比較少，膝蓋承受的垂直反作用力較大。著地時膝蓋看起來比較直，沒有達到一個緩衝的效果
-
🎯 研究顯示，比較「僵硬」跟「緩衝」的著地，前十字韌帶在有緩衝的著地所承所的應力相對減少了11% [Simonsen et al., 2000]。主要的原因是因為在著地的𣊬間，膝關節離心彎曲，腿後肌(hamstring)產生拉力減少脛骨(tibia)往前位移
-
🎯 前十字韌帶承受的應力減少，膝蓋受傷的機率也大大降低💯 在十字韌帶重建術後的訓練，除了訓練著地的技巧之外，腿後肌的強化訓練，對預防韌帶再次受傷也是很重要的
