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

    Author : Jennie Jackson; Svend Erik Mathiassen; Eva Vingård; Mikael Forsman; Peter Johnson; Högskolan i Gävle; []
    Keywords : 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

  4. 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 : 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

  5. 3. Ergonomics risk assessment methods for creating healthy work environments

    Author : Ida-Märta Rhén; Mikael Forsman; Teresia Nyman; Anna-Lisa Osvalder; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ergonomics; Risk assessment; Reliability; Validity; Systematic Observation; Direct measurement; Simulation; Digital Human Modelling; Workplace Design; Work-related Musculoskeletal Disorders; Biomechanical Exposure; Teknik och hälsa; Technology and Health;

    Abstract : Risk assessments of ergonomic conditions in pre-production and in field are necessary to prevent work-related musculoskeletal disorders and to increase productivity and quality. Methods for such assessments include simulations, direct measurements and observations. READ MORE

  6. 4. 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

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

    Author : Birgit Juul-Kristensen; Människan i rörelse: hälsa och rehabilitering; []

    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).
