Sense of touch restored for woman with bionic arm

Claudia Mitchell demonstrates the functionality of her 'thought-controlled bionic arm' during a news conference in Washington DC

A woman with an artificial arm has been given the sense of touch following a pioneering operation to reroute some of her nerves. Claudia Mitchell, 27, lost her left arm in a motorcycle accident three years ago, but can now feel her missing hand after having nerves from her lost limb rerouted to her chest.

Now, when she touches something with her artificial hand she can feel it through a device attached to her chest.

During a four-hour operation, surgeons moved nerves from her shoulder, which normally ferry signals from the hand to the brain, and redirected them to muscles in her chest area.

Four months after surgery, a patch of skin on her chest was able to feel touch, temperature and pain sensations as if they were coming from different parts of her hand and wrist.
