  1. 1. Trapezius muscle fatigue and electromyographic frequency analysis

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

    Sammanfattning : 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. LÄS MER

  3. 2. Strenght training and anabolic steroids : a comparative study of the trapezius, a shoulder muscle and the vastus lateralis, a thigh muscle, of strength trained athletes

    Författare :Anders Eriksson; Bengt Saltin; Umeå universitet; []
    Nyckelord :strength training; anabolic steroids; vastus lateralis; trapezius; enzymehistochemistry; immunohistochemistry; muscle fiber; myonuclei; satellite cell; anatomi; Human Anatomy;

    Sammanfattning : Strength training is widely used to increase performance in sports with high physical demands. The use of drugs such as anabolic steroids among athletes is a wellknown phenomenon, and the effects of these drugs on physical performance documented. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  7. 5. Effects of vibration on muscles in the neck and upper limbs : with focus on occupational terrain vehicle drivers

    Författare :Charlotte Åström; Gunnevi Sundelin; Lage Burström; Stefan Karlsson; Karin Harms-Ringdahl; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Electromyography; drivers; hand-arm vibration; trapezius; whole-body vibration; Physiotherapy; Sjukgymnastik fysioterapi;

    Sammanfattning : Introduction: Occupational drivers of terrain vehicles are exposed to several risk factors associated with musculoskeletal symptoms in the lower back as well as in the neck and upper limbs. Vibration has been suggested to be a main risk factor. These drivers are exposed to both whole-body vibration (WBV) and hand-arm vibration (HAV). LÄS MER
