Thought-controlled prosthesis

Rome, Italy | AP
"A group of European scientists said Wednesday they have successfully connected a robotic hand to an amputee, allowing him to feel sensations in the artificial limb and control it with his thoughts.

The experiment lasted a month, and scientists say it was the first time a patient has been able to make complex movements using his mind to control a biomechanic hand connected to his nervous system.

'The approach we followed is natural,' Rossini said. The patient 'didn't have to learn to use muscles that do a different job to move a prosthesis, he just had to concentrate and send to the robotic hand the same messages he used to send to his own hand.'

It will take at least two or three years before scientists try to replicate the experiment with a more long-term prosthesis, the experts said. First they need to study if the hair-thin electrodes can be kept in longer.
