Neurostimulation

Neurostimulation to Restore Sensoric Feedback Vortragssprache Deutsch Simultanübersetzung Englisch

Can prostheses deliver sensory feedback after loss of a limb due to amputation by means of neural implants ? This question has been investigated by a European consortium of medical doctors and engineers. This talk presents the results of the first clinical studies in patients with intraneural microimplants in the remaining nerves.

Nowadays, hand prostheses can be controlled by electrical signals of stump muscles after amputation. Information about grasp force, position of the hand and whether the object in the hand is currently deforming can be observed visually by the user’s eye, only. The desire to feed-back information about these objectives is as old as the history of hand prosthesis development. Worldwide, no approved medical device is available that offers such a functionality. A handful of research groups addresses the topic how electrical nerve stimulation can elicit perceptions of grasp force and properties and position of the hand in space. A European research consortium of medical and engineering groups developed intraneural electrodes that have been implanted transversally through the nerves of the affected limb. These microimplants with the acronym TIME (transversally intrafascicular multichannel electrodes) have been implanted for up to 6 months in four patients. The implants were stable, biocompatible and delivers reliable sensory feedback of force for safe and intuitive grasping. This talk presents results of the clinical trials and summarizes the challenges in translational research to transfer research results into medical devices that might get approved in the future.
