4. (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

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

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

13. Movement and Control
pattern recognition
Below Elbow amputation
• multiple electrodes on forearm
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

pattern recognition IV
• can be done
• limited by space for electrodes
and
• number of signals available
• suffers all drawbacks of surface EMG

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

27. 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!
