我的胳膊肘在一个礼拜前撞在了门上，到现在还很疼。

I bumped my elbow against the door a week ago. It still hurts.

在完全前够并且没有沉肘的时候，感觉好像你把你手指点到了一只枪管的前段（再收一点手腕），这就是抓水的开始。

At full reach and without dropping your elbow, feel like you are tipping your finger-tips over the front of a barrel (again flexing at the wrist), which will start the catch.

在C7神经根型颈椎病患者中，23%同时合并前臂旋前功能和伸肘功能减弱，另外，有10%患者只发现前臂旋前功能减弱。

In C7 radiculopathy subjects, forearm pronation weakness accompanies elbow extension weakness in 23% of subjects and was the only weakness in 10% of subjects.
