  1. 1. Bias and Precision in Biomechanical Exposure Assessment : Making the Most of our Methods

    Author : Jennie A. Jackson; Svend Erik Mathiassen; Eva Vingård; Mikael Forsman; Peter Johnson; Jennie A Jackson; Högskolan i Gävle; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; measurement strategy; accuracy; inclinometry; electromyography; EMG; upper arm; shoulder; low back; lumbar; thoracic; Health-Promoting Work; Hälsofrämjande arbete;

    Abstract : Background: Insufficient exposure assessment is a suggested contributing factor to the current lack of clearly characterised relationships between occupational biomechanical risk factors and musculoskeletal disorders. Minimal attention has been paid to the potential bias of measurement tools from expected true values (i.e. READ MORE

  2. 2. Efficient strategies for collecting posture data using observation and direct measurement

    Author : Per Liv; Svend Erik Mathiassen; Marina Heiden; Leif Nilsson; Ingvar Bergdahl; Stephen Bao; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Exposure assessment; arm elevation; exposure variability; variance components; random effects model; precision; bias; sample size; sample allocation; calibration; bootstrapping; Occupational and Environmental Medicine; arbets- och miljömedicin;

    Abstract : Relationships between occupational physical exposures and risks of contracting musculoskeletal disorders are still not well understood; exposure-response relationships are scarce in the musculoskeletal epidemiology literature, and many epidemiological studies, including intervention studies, fail to reach conclusive results. Insufficient exposure assessment has been pointed out as a possible explanation for this deficiency. READ MORE

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

    Author : Ida-Märta Rhen; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; MEDICIN OCH HÄLSOVETENSKAP; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; 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. 4. Observation Methods and Imaging Techniques. Assessments of physical exposure in repetitive work with focus on neck and upper extremities

    Author : Birgit Juul-Kristensen; Fysioterapi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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;

    Abstract : 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).

  5. 5. Cost-Efficient Designs for Assessing Work-Related Biomechanical Exposures

    Author : Mahmoud Rezagholi; Svend Erik Mathiassen; Apostolos Bantekas; Eva Vingård; Göran Hägg; Högskolan i Gävle; []
    Keywords : measurement strategy; postural loads; statistical performance; optimization; economic evaluation; resource allocation; input costs; cost function; returns to scale; elasticity; Arbets- och miljömedicin; Occupational and Environmental Medicine;

    Abstract : Work-related disorders due to biomechanical exposures have been subject to extensive research. Studies addressing these exposures have, however, paid limited attention to an efficient use of resources in exposure assessment. The present thesis investigates cost-efficient procedures for assessment of work-related biomechanical exposures, i.e. READ MORE
