  1. 21. Spatio-temporal processing of surface electromyographic signals : information on neuromuscular function and control

    Författare :Christer Grönlund; Leif Sörnmo; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EMG; multichannel surface electromyography; motor unit action potentials; conduction velocity; muscle architecture; signal quality; spatial distributions; synchronization; muscle function; motor control; biomedicinsk strålningsvetenskap; Biomedical Radiation Science;

    Sammanfattning : During muscle contraction, electrical signals are generated by the muscle cells. The analysis of those signals is called electromyography (EMG). The EMG signal is mainly determined by physiological factors including so called central factors (central nervous system origin) and peripheral factors (muscle tissue origin). LÄS MER

  3. 22. Diet and sarcopenia risk in community-dwelling older European adults

    Författare :Diego Montiel Rojas; Fawzi Kadi; Elodie Ponsot; Andreas Nilsson; Rikard Landberg; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Muscle mass; Muscle strength; Physical function; Healthy diet; Mediterranean diet; Macronutrients; Healthy ageing; Physical activity; Metabolic syndrome;

    Sammanfattning : The age-related decline in muscle strength and muscle mass can lead to sarcopenia with higher risk of falls, disability, and loss of independence. In this context, healthy dietary habits have the potential to delay onset of physical limitations, thereby promoting healthy ageing. LÄS MER

  4. 23. Critical illness myopathy : understanding different effects on muscle fibre function

    Författare :Hannah Ogilvie; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Skeletal muscle is an essential component of the human body, being one of the most dynamic and plastic tissues. As such it can be altered by numerous confounding factors. LÄS MER

  5. 24. Immunohistological studies on muscle biopsies : clinical and pathogenetic aspects on inflammatory myopathies

    Författare :Björn Lindvall; Göran Solders; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Inflammatory myopathies constitute a heterogeneous group of disorders comprising polymyositis (PM), dermatomyositis (DM), inclusion body myositis (IBM), as well as overlap syndromes where inflammatory myopathy is associated with different inflammatory systemic diseases, e.g, Sjögren's syndrome.

  7. 25. Structure and function of the ankle dorsiflexor muscles in young healthy men and women

    Författare :Anna Maria Drake; Människan i rörelse: hälsa och rehabilitering; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; kinesitherapy; revalidation; rehabilitation; Rehabilitering medicinsk och social ; Physical medicine; reproducibility of results; muscle fibres; magnetic resonance imaging; isokinetic strength; skeletal muscle; Ankle joint;

    Sammanfattning : The overall aim of this thesis was to increase our knowledge of the relationship between structure and function of human skeletal muscle, and about factors affecting strength. The ankle dorsiflexor muscles (DF) were chosen as a representative model of human skeletal muscle, and because these muscles have important roles in gait and maintenance of balance. LÄS MER
