An American woman has become the first in the world to receive a bionic arm that allows her to move the limb by the power of thought.
目前，一名美國婦女成為世界上首位擁有倣生手臂的人。倣生手臂的運動受人的思想的控制。
Claudia Mitchell, 26, lost her arm in a motorcycle crash.
26歲的克勞迪婭·米切爾在一次摩托車事故中失去了她的一條手臂。
Doctors re-routed nerves from her brain into the artificial limb via electrodes, and it is now said to operate as a normal human arm - and could even restore her sense of touch.
醫生將她大腦中的神經運動通過電極傳送到假肢裏。目前，米切爾的假肢據說可以像正常人的手臂那樣活動，甚至還可以恢復她的觸覺。
The former US Marine says the robotic arm, which weighs 5kg, has changed her life.
米切爾曾在美國海軍服役，她表示這只重達5公斤的機械手臂改變了她的生活。
With her previous prosthetic limb, she could only do one thing at a time - either open her elbow or open her hand.
以前的假手臂只能讓她一次幹一件事，要麼伸開她的肘關節，要麼張開她的手。
She had to concentrate on flexing her pectoral muscle, or the triceps, to power the arm.
為了給手臂提供力量，她不得不用力伸縮她的胸肌或者三頭肌。
"Now I just think about it," she added. "This might be bigger and feel a little awkward, but the amount of function that I get out of it makes it worth wearing it."
她補充說：“現在我只是在想，這只手臂可能大了點，感覺也有些笨拙，但是它具備的眾多功能讓我覺得值得安裝上它。”
It is hoped hundreds of American soldiers who have lost limbs in Iraq and Afghanistan will benefit from the revolutionary treatment.
數百名在伊拉克和阿富汗戰爭中失去手臂的士兵有希望從這次醫學革命性中受益。
