1. 6. Touching on elements for a non-invasive sensory feedback system for use in a prosthetic hand

   Författare :Pamela Svensson; Avdelningen för Biomedicinsk teknik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sensory feedback; amputation; referred sensation; non-invasive feedback; upper limb prosthetics; body ownership;

   Sammanfattning : Hand amputation results in the loss of motor and sensory functions, impacting activities of daily life and quality of life. Commercially available prosthetic hands restore the motor function but lack sensory feedback, which is crucial to receive information about the prosthesis state in real-time when interacting with the external environment.

3. 7. Electromyogram Signal Enhancement and Upper-Limb Myoelectric Pattern Recognition

   Författare :Sara Abbaspour; Maria Lindén; Christian Antfolk; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; elektronik; Electronics;

   Sammanfattning : Losing a limb causes difficulties in our daily life. To regain the ability to live an independent life, artificial limbs have been developed. Hand prostheses belong to a group of artificial limbs that can be controlled by the user through the activity of the remnant muscles above the amputation. LÄS MER

4. 8. Motion Analysis and Postural Stability of Transtibial Prosthesis Users

   Författare :David Rusaw; Göteborgs universitet; []
   Nyckelord :Artificial limb; balance; electromyography EMG ; motion analysis; postural stability;

   Sammanfattning : The AIMS of the thesis were to critically evaluate motion analysis methods used during investigations of transtibial prosthesis users, and to propose improvements to these methods. Additionally, the aim was to evaluate if vibratory feedback could be used to improve postural stability in transtibial prosthesis users and how being a prosthesis user influenced muscular response to postural perturbations.

5. 9. Embedded Controller for Artificial Limbs

   Författare :Enzo Mastinu; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Prosthetic Controller; Pattern Recognition; Osseointegrated Human-Machine Gateway OHMG ; Electromyography EMG ; Osseointegration.; Sensory Feedback;

   Sammanfattning : Promising developments are currently ongoing worldwide in the field of neuroprosthetics and artificial limb control. It is now possible to chronically connect a robotic limb to bone, nerves and muscles of a human being, and use the signals sourced from these connections to enable movements in the artificial limb.

7. 10. Towards Natural Control of Artificial Limbs

   Författare :Max Jair Ortiz Catalan; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; epimysial electrodes; robotic prostheses; sensory feedback.; real-time and simultaneous prosthetic control; neurostimulation; pattern recognition; advanced prosthetic control; neural interfaces; artificial limbs; cuff electrodes; bone-anchored prostheses; osseointegration;

   Sammanfattning : The use of implantable electrodes has been long thought as the solution for a more natural control of artificial limbs, as these offer access to long-term stable and physiologically appropriate sources of control, as well as the possibility to elicit appropriate sensory feedback via neurostimulation. Although these ideas have been explored since the 1960’s, the lack of a long-term stable human-machine interface has prevented the utilization of even the simplest implanted electrodes in clinically viable limb prostheses.
