Statement of objectives:
This workshop is about human-machine interfaces which connect non-invasively to the peripheral nervous system (PNS-MIs), surface electromyography (sEMG) being the paradigmatic PMI. sEMG is in use since the 60s to proportionally control single-DoFs hand prostheses. It involves neither surgery nor hospitalisation; its signal remains rich in information even decades after an amputation, and provides clearer signals than brain-computer interfaces such as, e.g., electroencephalography.
Since then literally dozens different approaches have been applied to sEMG to decode an amputee's intentions, but none of them have as yet made it to the clinics: as a PMI, sEMG has revealed to be unreliable, badly conditioned, subject to change with time, fatigue and sweat. No valid alternatives to sEMG are in sight, and nevertheless, dexterous prosthetic hands are now appearing on the market, demanding ever better control by the patient.
So, how can we bridge this gap? We address four fundamental sub-problems:
1. what is wrong with the current approach? why do clinicians not use it?
2. how can we better use sEMG?
3. what alternative, radically new solutions are available, if any?
4. what are the benefits of sharing control between the human subject and the prosthesis?
The workshop revolves around the four themes spanned by the above questions: current limitations, sEMG, novel techniques and control. The workshop will bring together roboticists, clinicians and neuroscientists interested in these questions. We foresee participation of interested young scientists, whose interaction with the experts will foster discussion and possibly indicate some ways ahead. At the end of the workshop we will have an indication of how to direct current research efforts in order to solve each of the aforementioned problems.

Todd KuikenTodd A. Kuiken received his MD and Ph.D. in biomedical engineering from Northwestern (1990) and his residency in PM&R at the Rehabilitation Institute of Chicago (1995). Dr. Kuiken currently is the Director of the Center for Bionic Medicine. He is a Professor in the Depts. of PM&R, Biomedical Engineering and Surgery of Northwestern University. Dr. Kuiken’s research team is working to develop a neural-machine interface to improve the function of artificial limbs. A main research focus of the lab is developing a technique to use nerve transfers for improvement of myoelectric prosthesis control. By transferring the residual arm nerves in an upper limb amputee to spare regions of muscle it is possible to make new signals for the control of robotic arms. These signals are be directly related to the original function of the limb and allow simultaneous control of multiple joints in a natural way. This work has now been extended with the use of pattern recognition algorithms, enabling the intuitive control of more functions it the prosthetic limbs. Similarly, hand sensation nerves grow into spare skin so that when this skin is touched, the amputee feels like their missing hand is being touched.


Marko MarkovicMarko Markovic received the B.Sc. degree in biomedical engineering from Faculty of Electrical Engineering, Belgrade, Serbia, in 2010, and later the M.Sc. degree within the same institution in 2011. He is currently employed as the research associate in the Department ofNeurorehabilitation Engineering at the University Medical Center Gottingen, where he is also working towards his PHD degree.
