  2. 11. Musicianship and teaching : aspects of musculoskeletal disorders, physical and psychosocial work factors in musicians with focus on music teachers

    Author : Anncristine Fjellman-Wiklund; Gunnevi Sundelin; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; music; musician; teaching; occupational; musculoskeletal; psychosocial aspect; mind-body; tai chi chuan; basic body awareness therapy; electromyography;

    Abstract : Musculoskeletal disorders are common among musicians at all levels of performance. Since music teachers train our future musicians it is important to understand their work environment. By creating good examples of a healthy work environment, they can teach their students how to stay healthy and to prevent pain. READ MORE

  4. 12. Effects of low-load repetitive work and mental load on sensitising substances and metabolism in the trapezius muscle

    Author : Gerd Flodgren; Gisela Sjøgaard; Umeå universitet; []
    Keywords : work-related muscle pain; microdialysis; near-infrared spectroscopy; electromyography; glutamate; lactate; pyruvate; prostaglandin E2; norepinephrine; Occupational and Environmental Medicine; arbets- och miljömedicin;

    Abstract : Low-load repetitive work (LLRW) and mental load are important risk factors for the development of workrelated muscle pain. The link between these risk factors and the development of pain is still not understood, but stimulation of chemo-sensitive receptors in the muscle probably plays an important role. READ MORE

  5. 13. Evaluation of physical work capacity and leg muscle fatigue during exhaustive stair ascending evacuation

    Author : Amitava Halder; Ergonomi och aerosolteknologi; []
    Keywords : Stair climbing; Energy expenditure; Oxygen consumption; Electromyography; Muscle fatigue;

    Abstract : AbstractPhysical exhaustion can constrain human ascending work capacity and performance during emergency evacuation on stairs. The overall aim of this research was to explore and compare stair ascending capacities and physiological limitations during two different strategies: self-preferred pace in three different public stairways in the field, and controlled pace in a laboratory on a stair machine.

  6. 14. Seated postural reactions to mechanical shocks : laboratory studies with relevance for risk assessment and prevention of musculoskeletal disorders among drivers

    Author : Tobias Stenlund; Börje Rehn; Ronnie Lundström; Ola Lindroos; Fredrik Öhberg; Rolf Moe-Nilssen; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Postural balance; Posture; Electromyography; Musculoskeletal pain; Whole-body vibration; Reliability; Kinematics; Biomechanics; sjukgymnastik; Physiotherapy;

    Abstract : Professional drivers of off-road vehicles, driving on irregular terrain such as in forestry, agriculture and mining, are exposed to whole-body vibration and mechanical shocks. These driver groups have reported severe musculoskeletal problems in the spine, but the association to seated postural reactions is not fully understood. READ MORE

  7. 15. The Fight on the Flights : Emergency evacuations – human physiological performance, leg muscle activity and gait biomechanics during exhaustive stair and slope ascent

    Author : Amitava Halder; Ergonomi och aerosolteknologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Stair climbing evacuation; Physical work capacity; Physiological constraints; Endurance; Energy expenditure; Oxygen consumption; Electromyography; Muscle fatigue; Incline gait biomechanics; Ground reaction forces; Required coefficient of friction;

    Abstract : Physical exhaustion can constrain stair ascending capacity during emergency evacuation. The overall aim of this research was to explore and compare stair ascending capacities and physiological limitations when using two different modes: 1) self-preferred pace on three different public stairways, and 2) four machine-controlled paces on a stair machine corresponding to different percentages of maximal aerobic capacity (V̇O2max).
