  1. 1. Physical load, psychosocial and individual factors in visual display unit work

    Author : Jens Wahlström; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; computer work; musculoskeletal symptoms; working; technique; psychosocial factors; physical load; muscular tension; mental; stress;

    Abstract : The overall aim of this thesis was to explore associations between physicalload, psychosocial and individual factors in visual display unit (VDU)work. Furthermore, the aim was to investigate whether perceived musculartension is a predictor of neck pain among VDU operators. READ MORE

  2. 2. Muscular forces from static optimization

    Author : Sofia Heintz; Anders Eriksson; Elena Gutierrez-Farewik; Anton Arndt; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; movement analysis; muscle forces; static optimization; Other engineering mechanics; Övrig teknisk mekanik;

    Abstract : At every joint there is a redundant set of muscle activated during movement or loading of the system. Optimization techniques are needed to evaluate individual forces in every muscle. The objective in this thesis was to use static optimization techniques to calculate individual muscle forces in the human extremities. READ MORE

  3. 3. Physical load in computerized office work : with special reference to work tasks and equipment

    Author : Elisabeth Fernström; KTH; []
    Keywords : ;

    Abstract : The main purpose of the studies presented in this thesis wasto measure and quantify shoulder load in computerised officework. Shoulder load was studied during a whole working day andin different work tasks. Shoulder and arm load during keyboardwork and with different modes of physical computer interactionwas also studied.

  4. 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; 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

  5. 5. Biomechanical and neural aspects of eccentric and concentric muscle performance in stroke subjects : Implications for resistance training

    Author : Mattias Hedlund; Britta Lindström; Peter Sojka; Ronnie Lundström; Carl-Johan Olsson; Jan Lexell; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; fMRI; Isokinetic; Motor imagery; Muscular strength; Resistance training; Neurological rehabilitation;

    Abstract : Muscle weakness is one of the major causes of post-stroke disability. Stroke rehabilitation programs now often incorporate the same type of resistance training that is used for healthy subjects; however, the training effects induced from these training strategies are often limited for stroke patients.
