Claim: Patrick Mayrhofer's doctor, Oskar Aszmann, worked with Ottobock, a German prosthetics company from Berlin, to create Mayrhofer's prosthetic hand.
Evidence: His surgeon Dr. Oskar Aszmann from the University of Vienna worked close together with the prosthesis technology company Ottobock. After this, he was fitted with a groundbreaking prosthesis, known as a "Michelangelo Hand", The elective amputation allows Mayrhofer to control the prosthesis in the same way as non-amputees do: EMG electrodes in the prosthesis detect muscle signals within the lower arm which can be used for prosthesis control.
