(Why) do they matter?
Do they matter in our field????

Medical Device development
1. You don‘t know what you don‘t know
2. Regulatory Red Tape can be avoided by being smart
3. Work with experienced partners with trusted relationships only
4. Documentation, Documentation and more Documentation

Control and Mechanics of Prosthetic Devices
upper extremity human • Human anatomy
– 20+ DOF (incl. hand)
• perfect control
– life-long learning phase
– proprioception
– Feedback
– force
– temperature – humidity
– …............
Human arm vs. prosthetic device
Commercial prosthesis • Mechanics
– maximum 4-6 DOF
• Control
– sequential control
– pattern recognition with simultaneous control emerging
– no proprioception
– no Feedback, although field of interest in research

Revolutionizing Prosthetics (DARPA) Results
Challenge • Upper extremity
– 20+ DOF
– perceived low weight
– intutitive control
– feedback

State of the Art Technology
How to control your arm in daily life • type of control: sequential/simultaneous
• # of signals required
• external factors
• Functionality?
- How much is required?
Is there anything missing?

Movement and Control
Below Elbow amputation • multiple electrodes on forearm
pattern recognition
Above Elbow amputation • biceps & triceps available → number of signals (very) limited
• extra DOF in elbow required
Shoulder exarticulation • extra DOF in shoulder required
• no signals available without surgery → TMR

Movement and Control
• can be done
• limited by space for electrodes
and
• number of signals available
• suffers all drawbacks of surface EMG

Movement and Control
• International research topic
• muscle electrodes are proven designs
• nerve interfaces are difficult to control
• mechanical stability is difficult to achieve

mobile, wearable, smart tech
Conclusion • devices are mobile and wearable • they are (very) smart-tech
• perfect integration difficult • control not always easy to achieve
• regulatory red tape is difficult to handle • we do document a lot!
