  2. 1. 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

  4. 2. Muscular activity in light manual work - with reference to the development of muscle pain among computer users

    Author : Stefan Thorn; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cinderella hypothesis; myalgia; muscle rest; doublets; extensor digitorum communis muscle; motor units; computer work; intramuscular electromyography; trapezius muscle;

    Abstract : Work related musculoskeletal disorders (WMSDs) in the neck/shoulder area and the upper extremities are common among computer users, despite the relatively low muscle load levels involved. Muscle pain (myalgia), primarily experienced in the neck/shoulder area, is a frequent type of WMSD. READ MORE

  5. 3. Trapezius muscle fatigue and electromyographic frequency analysis

    Author : Tommy Öberg; Linköpings universitet; []
    Keywords : EMG; Spectrum; Frequency; Fatigue; Trapezius; Myalgia; MEDICINE; MEDICIN;

    Abstract : This study, comprising 6 separate articles, is concerned with different validity and reliability aspects of the electromyogram mean power frequency (MPF) as an estimator of localized musele fatigue in the trapezius muscle. A series of new, and partly controversial and problematic findings are reported. READ MORE

  6. 4. Work-related musculoskeletal disorders - exposure assessment and gender aspects

    Author : Catarina Nordander; Avdelningen för arbets- och miljömedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Skelett; Occupational health; Yrkesmedicin; industrial medicine; arbetsmiljömedicin; reumatologi; muskelsystem; rheumatology locomotion; muscle system; Skeleton; repetitive work; sex; occupational; myalgia; Surface EMG; muscular activity;

    Abstract : Work-related musculoskeletal disorders are widespread, and are, for unclear reasons, more common among females than in males. Several risk factors have been described; constrained and awkward postures, repetitive and/or force demanding motions, and lack of recovery. READ MORE

  7. 5. Applying proteomics and metabolomics for studying human skeletal muscle with a focus on chronic trapezius myalgia

    Author : Jenny Hadrévi; Albert Crenshaw; Fatima Pedrosa-Domellöf; Fredrik Hellström; Bijar Ghafouri; Mary F Barbe; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Trapezius myalgia; proteomics; 2D-DIGE; metabolomics; microdialysate; biopsies; anatomi; Human Anatomy;

    Abstract : Work related musculoskeletal disorders are the dominating causes of reported ill-health in industrialized countries. These chronic pain conditions are one of the most costly public health problems in Europe and North America. READ MORE
