經過手肘手術的他，原本就有問題的投擲，變得更加嚴重，導致不只手肘有壓力，肩膀也開始痛起來。

Client underwent an elbow surgery which cause the problems even worse, which result to his shoulder pain and stress on elbow.

經過半年多的訓練，終於得到很大的進展！ Finally we see huge improve after half year.

主要進步：

肩膀/軀幹連鎖反應 軀幹/肩膀活動度 手臂與手臂間的連結 脊椎的屈曲與肩胛骨的前引

Major improvements Shoulder/Trunk reciprocation Shoulder/Trunk mobility Connection between both arms Spine flexion and scapula protraction 我們的身體一個部位產生動作時，另一個部位必須產生相對動作，我們稱為reciprocation，也能說連鎖反應。

然而他以前的訓練要他不停的伸展、關節鬆動，讓他的身體做不出連鎖反應，這會造成關節動作時位置跑掉，也容易受傷、力量使不出。 當他的手臂在產生外轉時，軀幹也該產生相應對的動作，但他以前不會。

When we move one part of our body, other part of body need to reciprocate that motion. However he used to do a lot of stretching,mobility drills which leads to no reciprocation between his arm and trunk when rotate. It is harmful for constant stretching. Stop ✋.

自從慢慢掌握這個概念後，投擲更有力，也更安全，也不會痛。

Now he is more confident,safer and no pain!
