Patrick Mayrhofer's doctor, Oskar Aszmann, worked with Ottobock, a German prosthetics company from Berlin, to create Mayrhofer's prosthetic hand.
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.
