  2. 1. Development, application, and reliability of methods for ergonomic workload assessments in production evaluation and workstation design

    Author : Ida-Märta Rhen; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Work-related Musculoskeletal Disorders; Risk assessment; Direct measurement; Biomechanical Exposure; Systematic Observation; Digital Human Modelling; Ergonomics; Workplace Design; Simulation; Reliability;

    Abstract : Ergonomics assessments of conditions for humans at workstations and in manufacturing processes are necessary to prevent work-related musculoskeletal disorders and enhance efficiency and quality. Many methods can be used for this from systematic observations to direct measurements and simulation. READ MORE

  4. 2. Musculoskeletal disorders in demanding computer work - with air traffic control as a model

    Author : Inger Arvidsson; Avdelningen för arbets- och miljömedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prospective study; psychosocial work environment; neck-postures; technical measurements; physical exposure; computer mouse; VDU-work; diagnoses; Neck and upper limb disorders; physical examination;

    Abstract : In computer work, musculoskeletal disorders are frequently reported, but the knowledge about causal relationships is limited. In air traffic control, female and male operators perform exactly the same computer work. READ MORE

  5. 3. PRODUCTION ERGONOMICS EVALUATION - NEEDS, PROCEDURES AND DIGITAL HUMAN MODELING TOOLS

    Author : Cecilia Berlin; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Cumulative; Production Ergonomics; Digital Human Modeling; Prevention; Musculo-Skeletal Disorders; DHM; Time; Virtual Tools;

    Abstract : In production systems, human operators may be at risk for developing work-related musculoskeletal disorders (MSDs), resulting in pain, inability to work and high costs. An increasingly capable tool for identifying MSD risks early in the production design process are Digital Human Models (DHMs), although their built-in analysis tools are in great need of development regarding how they address time-related aspects of load exposure.

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

    Author : Dag Rissén; Bo Melin; Ulf Lundberg; Anders Kjellberg; Stockholms universitet; []
    Keywords : 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;

    Abstract : 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.

  7. 5. 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
