1. 6. Neuromusculoskeletal interfacing of lower limb prostheses

   Författare :Alexander Thesleff; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; OPRA; bone-anchored attachment; Enhanced Osseointegrated Prostheses for the Rehabilitation of Amputees e-OPRA .; Osseointegration; direct skeletal attachment; neuromusculoskeletal interface; OPRA; Osseointegrated Prostheses for the Rehabilitation of Amputees OPRA ; Enhanced Osseointegrated Prostheses for the Rehabilitation of Amputees e-OPRA .;

   Sammanfattning : The method of bone-anchored attachment of limb prostheses via a percutaneous skeletal extension was developed to circumvent commonly reported problems associated with the conventional method of socket attachment. In addition to the direct structural connection, the percutaneous implant may serve as a conduit for bidirectional communication between muscles and nerves within the residual limb and the prosthesis.

3. 7. 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.

4. 8. The electromyographic signal used for control of upper extremity prostheses and for quantification of motor blockade during epidural anaesthesia

   Författare :Lennart Philipson; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : A contribution of biomedical research engineering has been the development of detection and analysis methods for the electromyographic (EMG) signal and its application to health care problems. The present thesis describes the use of EMG signals for two such applications: Aid in the control of multifunctional upper limb prostheses and for quantification of motor blockade during epidural anaesthesia.

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.
