  4. 2. Myoelectric Control for Hand Prostheses

    Author : Fredrik Sebelius; Avdelningen för Biomedicinsk teknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mät- och instrumenteringsteknik; Care and help to handicapped; Handikappade; vård och rehabilitering; Instrumentation technology; Virtual; Recognition; Real time; On-line learning; Myoelectric; Hand prosthesis; EMG; ANN; Artificial hands;

    Abstract : An investigation of improvements of myoelectric prostheses has been undertaken. The primary aims of this thesis were (1) to generate an accurate prediction of as many hand movement as possible, (2) to produce a training setup for subjects allowing intuitive and instant control over multiple movements, and (3) to reduce the training cycle for the control system to a maximum of a couple of minutes to enable optimizations, e.

    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Accommodation; Asthenopia; Computer work; Eye-neck head stabilization; Muscle activity; Neck pain; Visual Attention; Visual demand; Visual ergonomics; Medicinsk vetenskap; Medical Science;

    Abstract : Introduction: Musculoskeletal discomfort in the neck and shoulders is common among workers performing visually demanding near work, e.g., on a computer screen, and sustained low-level muscle activity during such work can lead to work-related pain. READ MORE

  6. 4. Proposing Combined Approaches to Remove ECG Artifacts from Surface EMG Signals

    Author : Sara Abbaspour; Maria Lindén; Urban Wiklund; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Electromyography (EMG) is a tool routinely used for a variety of applications in a very large breadth of disciplines. However, this signal is inevitably contaminated by various artifacts originated from different sources. READ MORE

  7. 5. Morphological and electromyographical studies of trapezius myalgia in cleaners

    Author : Britt Larsson; Avdelningen för arbets- och miljömedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; female cleaners; Trapezius myalgia; work-related; arbetsmiljömedicin; Yrkesmedicin; industrial medicine; Occupational health; morphological analysis and surface-EMG;

    Abstract : Pathomechanisms of work-related myalgia are poorly understood. Myalgia is caused by exitation of nociceptors present in the muscular tissue but not in the muscle fibres themselves. Morphological analysis can contribute to knowledge of excitation of nociceptors. Surface EMG is a widely used method in the research field of ergonomics. READ MORE
