ERGONOMICS AND MUSCULOSKELETAL DISORDERS

NIOSHTIC-2 search results on Ergonomics and Musculoskeletal Disorders NIOSHTIC-2 is a searchable bibliographic database of occupational safety and health publications, documents, grant reports, and journal articles supported in whole or in part by NIOSH.

In the early 2000s, NIOSH funded 10 field-based studies to examine the exposure-response relationship between job physical risk factors and work-related musculoskeletal disorders. The studies focused on either the lower back or the upper extremity. Each of these studies addressed limitations of previous research on work-related musculoskeletal disorders by (1) having a prospective design; (2) making direct and quantitative measurements of job physical risk factors; (3) assessing psychosocial and work organization factors; (4) collecting self-reported symptoms; and (5) assessing musculoskeletal symptoms and disorders through physical examinations.

The results of many of these studies are compiled and published in a special issue of a peer-reviewed journal. These studies presented below collectively show a strong link between job physical exposures and work-related musculoskeletal disorders.

Clinical Guidelines for Occupational Lifting in Pregnancy: Evidence Summary and Provisional Recommendations
Empirically-based lifting criteria established by the National Institute for Occupational Safety and Health (NIOSH) to reduce risk of overexertion injuries in the general U.S. working population were evaluated for application to pregnant workers. This report proposes criteria to guide decisions by medical providers about permissible weights for lifting tasks performed at work over the course of an uncomplicated pregnancy. Our evaluation included an extensive review of the literature linking occupational lifting to maternal and fetal health. Although it has been 29 years since the American Medical Association’s (AMA) Council on Scientific Affairs published its report on the Effects of Pregnancy on Work Performance, these guidelines continue to influence clinical decisions and workplace policies. Provisional clinical guidelines derived from the NIOSH lifting criteria are presented that account for recent evidence for maternal and fetal health, and aim to improve the standard of care for pregnant workers.
