United States marine Claudia Mitchell lost her arm two years ago in a motorcycle accident and applied for a prosthetic arm that can be moved by the thought. She contracted the doctors after reading about early bionic experiments on male patients. She is the first female patient who has received the prosthetic arm. She is now able to feel heat and the pressure of a handshake.
Her artificial arm operated like a normal human limb. The bionic limb is rerouting nerves from the brain that used to terminate in the hand. The nerves are redirected from the shoulder to the chest and from the chest they grow into the muscle from where the commands are directed to the bionic arm using electrodes. These electrodes are communicating with a computer in the limb, which is controlled by six small motors.
The important thing is that nothing is being implanted into the body. Now, the patients are not only able to move their hands but they are also able to open jars, reach up to high shelves and dress themselves more easily. They can even feel the heat and cold.

It takes five months until the patient who received the artificial arm is able to use it. It takes that long for the redirected nerves to be able to operate the arm.
Scientists are hoping that this piece of technology will help more than 400 people who lost their limbs while serving in Afghanistan and Iraq.
