Mind-Controlled Prosthetic Arm can move fingers individually

Engineers from Johns Hopkins University have developed mind-controlled prosthetic arm that can move fingers individually and independently of each other. This is really good news for people with disabilities who have lost arms due to disease or injury. The young man on the video below was equipped with a device that use a brain-computer interface to control of his own arm and hand.

The subject uses his mind to move individual fingers on a prosthetic arm:

Nathan Crone, professor of neurology at the Johns Hopkins University, says:

“We believe this is the first time a person using a mind-controlled prosthesis has immediately performed individual digit movements without extensive training”.

But this innovative mind-controlled prosthesis is not a universal device for each patient. Before connecting the prosthesis, the researchers studied the patient’s brain signals that move hand and each finger, and then programmed the prosthesis to react to brain signals correctly. To date, the accuracy of the mind-controlled limb increased to 88 percent.
