Covariation between workplace physical and psychosocial stressors: evidence and implications for occupational health research and prevention

Article Abstract:

Work environments with psychosocial and physical stressors have shown moderate to high covariation, with the strongest covariation among low-status office and blue-collar production workers. Epidemiologic studies should include information about the level of association between task-level stressors.

Digital vibration threshold testing and ergonomic stressors in automobile manufacturing workers: A cross-sectional assessment

Article Abstract:

The extent of association between digital vibration thresholds (VTs) and exposures to ergonomic stressors in automobile manufacturing workers is examined. The results indicate that awkward postures, contact stress, and hand force factors may be associated with VTs, but as these exposures are self-reported, further epidemiologic studies are required to clarify these associations.evl

Estimation of compressive forces on lumbar spine from categorical posture data

Article Abstract:

Continuous variables for body angles are estimated by assuming specified distributions within corresponding posture categories with Monte-Carlo (MC) simulation to combine estimates of trunk posture and force into an integrated measure of load on the low back. A simulation approach combined with biomechanical modeling could be used to integrate multiple external exposure variables into estimates of compressive forces acting on the low back.
