In modern prosthetics research is done in a wide variety of fields. One direction focuses on the bionic principle, replacing bodily functions with technology. Based on physical structures, motor and sensory nerves in the body are addressed which is recognized by the brain as a signal. The goal of all bionic prostheses is the idea of closer acceptance into self perception. At the Medical University Innsbruck and the private clinic Brixsana, a technique has been developed to redirect sensory nerves to the skin area of the stump and thus allow those affected to feel authentic. Prof. Dr. Hubert Egger has collaborated with Dr. Ing. Eva Maria Baur and carried out this reinnervation in a world’s first.

Feeling Prosthesis

How can a prosthesis feel? How does it work? In a video coming soon, Hubert Egger will explain how he came up with the idea of providing feeling to a leg and foot prosthesis.
