SC4 – Bionic Prosthetics in Medicine and Technology

Lecturer: Cosima Prahm
Fields: Medicine/Neuroscience/Machine Learning

Content

Although the hand represents only 1% of our body weight, most of our sensorimotor cortex is associated with its control. The loss of a hand therefore not only signifies the loss of the most important tool with which we can interact with our environment, but also leaves us with a drastic sensory-motor deficit that challenges our central nervous system. Restoring hand function is therefore not only an essential part of restoring physical integrity and functional employability, but also closes the neural circuit, thereby reducing phantom sensations and nerve pain.

When there is no longer sufficient anatomy to restore meaningful function, we can resort to complex robotic replacements whose functional capabilities in some respects even surpass biological alternatives, such as conservative reconstructive measures or transplantation of a hand. However, as with replantation and transplantation, the challenge with bionic robotic replacements is to solidly attach it the skeleton and connect the prosthesis to our neural and muscular system to achieve natural, intuitive control and also provide basic sensory feedback.

This interdisciplinary course will discuss the progressive development of upper extremity robotic prosthetics in the fields of bioengineering, medicine, computer science, and neuroscience. We address the medical basis of biosignals, movement, amputation and restoration, and various systems of prosthetic limbs to restore physical integrity. We will discuss enhancement versus restoration and how to improve the man-machine-interface, exemplified with case studies.
