示指伸肌怎么了

Extensor Indicis

Extensor indicis

前臂外侧少见

这块肌肉是什么

从尺骨背面连到示指，可以单独伸直食指。

单独用食指点、敲；前臂尺侧背面反复伸。

前臂背侧靠近尺骨一小段酸；只伸食指时明显，别的手指还好。

食指屈向掌心，轻轻屈腕，停20秒。

Outer forearm · Uncommon

From the back of the ulna to the index finger. It can straighten the index finger on its own.

Pointing and tapping with the index finger alone; the back of the forearm on the ulna side straightening over and over.

A short sore stretch on the back of the forearm, near the ulna; obvious when only the index finger straightens, while the other fingers are fine.

Bend the index finger toward the palm and gently bend the wrist. Hold 20 seconds.
