  1. 1. 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. 2. Towards clinically viable neuromuscular control of bone-anchored prosthetic arms with sensory feedback

    Författare :Enzo Mastinu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electromyography; prosthetics; sensory feedback; closed-loop; osseointegration; embedded system; pattern recognition; neurostimulation;

    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 to use the signals sourced from these connections to enable movements of the artificial limb.

  4. 3. High-Density Electromyography-Based Methods for Joint Torque Prediction and Motor Unit Behavior Observation

    Författare :Asta Kizyte; Ruoli Wang; Elena Gutierrez-Farewik; Christian Antfolk; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ankle; isometric contractions; machine learning; neuromuscular control; spinal cord injury; Fotled; isometriska kontraktioner; maskininlärning; neuromuskulär kontroll; ryggmärgsskada; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : Electromyography (EMG) is a technique that measures the electrical activity of muscles. It reflects muscle activation and provides an interface to the central nervous system at the level of the muscle or individual motor units, which helps us understand the mechanisms of muscle force production, control, and coordination.

  5. 4. Biomechanical Parameter Estimation for Wearable Exoskeleton System Design

    Författare :Longbin Zhang; Elena Gutierrez Farewik; Ruoli Wang; Christian Smith; Max Ortiz Catalan; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hill-type muscle model; generalization; transfer learning; computationally modeling; human-machine system; Engineering Mechanics; Teknisk mekanik;

    Sammanfattning : Exoskeletons are increasingly used in rehabilitation and daily life in persons with motor disorders after neurological injuries. The overall objective of this thesis is to study how to robustly and accurately predict joint torque using inputs from sensors that would technically be feasible to equip on an assistive exoskeleton, and to develop a framework that could be used to evaluate the user-exoskeleton interface.
