Nine years ago, Dennis Aabo Sørensen severely wounded his left arm in a fireworks accident, and had to have it amputated. Now, a bionic hand has restored his ability to feel, the first time this has been reported in a scientific journal.
Researchers embedded electrodes in Sørensen's arm, and touch sensors in a prosthetic handto stimulate his remaining nerves. With the hand, Sørensen was able to recognize different objects by their feel, and grasp them appropriately, according to the study detailed online today (Feb. 5) in the journal Science Translational Medicine.
"I could feel things that I hadn't been able to feel in over nine years," Sørensen, who lives in Denmark, said in a statement.
So far, Sørensen is the only person to test the prosthesis, and he's had it for only a short time, but if proven to work over the long term in more people, the system could vastly improve the function of current prosthetic limbs and the quality of life for their users.
