  1. 1. Effects of repetitive work on proprioception and of stretching on sensory mechanisms : implications for work-related neuromuscular disorders

    Författare :Martin Björklund; Håkan Johansson; Albert Crenshaw; Ronny Lorentzon; Måns Magnusson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Repetitive motions; Muscle fatigue; Proprioception; Muscle stretching; Work-related musculoskeletal disorders; Nociception; Ergonomics; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; medicin; Medicine;

    Sammanfattning : The aims of the thesis were (i) to investigate the impact of repetitive low-intensity work exposure on proprioception and (ii) to examine effects of muscle stretching (especially sensory effects and effects on muscle nociception) and to relate its application to the prevention, alleviation and/or treatment of work-related neuromuscular disorders. The effects of low-intensity repetitive work on the shoulder proprioception were tested in healthy subjects. LÄS MER

  3. 2. Production Systems for Manual Repetitive Jobs. Effects on Autonomy and Variety of Work and Prevalence of Musculoskeletal Disorders in Upper Limbs

    Författare :Marita Christmansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; work design; manual repetitive jobs; task design; upper limbs; production system design; autonomy; musculoskeletal disorders; assembly jobs; variety; work behavior;

    Sammanfattning : The aim of this thesis is to improve workers' conditions and it deals particularly with companies in the engineering industry. In many of these companies, production systems are designed to have manual repetitive jobs. LÄS MER

  4. 3. Repetitive and monotonous work among women : Psychophysiological and subjective stress reactions, muscle activity and neck and shoulder pain

    Författare :Dag Rissén; Bo Melin; Ulf Lundberg; Anders Kjellberg; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Repetitive and monotonous work; women; psychophysiological stress reactions; subjective stress reactions; muscle activity; trapezius muscle; neck and shoulder pain; job rotation; Psychology; Psykologi;

    Sammanfattning : Repetitive and monotonous work is frequently associated with neck and shoulder pain and negative psychosocial factors inducing stress reactions. The present thesis concerns the relations between psychophysiological and subjective stress reactions, muscle activity measured by surface electromyography (SEMG) in the trapezius muscle, and neck and shoulder pain in women performing repetitive and monotonous work.

  5. 4. Observation Methods and Imaging Techniques. Assessments of physical exposure in repetitive work with focus on neck and upper extremities

    Författare :Birgit Juul-Kristensen; Människan i rörelse: hälsa och rehabilitering; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; imaging techniques; force; electromyography; video recording; electrogoniometer; inclinometer; movement; posture; physical exposure; industrial work; repetitive; upper extremity; neck; observation method; musculoskeletal; Yrkesmedicin; arbetsmiljömedicin; industrial medicine; Occupational health; epidemiology; ultrasound; magnetic resonance;

    Sammanfattning : Observation methods and imaging techniques - assessments of physical exposure in repetitive work with focus on neck and upper extremities The aim of this thesis was to develop, establish and validate observation methods for exposure assessments in epidemiological studies of repetitive work. A second aim was to increase the quality of input data for biomechanical shoulder models, by reliability and validity studies of Magnetic Reso-nance Imaging (MRI) and Ultrasound Scanning (US).
