[Why do musculo-skeletal stress injuries increase?].

J Winkel

    Nordisk Medicin
    |January 1, 1989
    PubMed
    Summary

    Technological advancements have led to less physical activity at work, yet musculoskeletal symptoms persist. Research suggests a U-shaped curve where both high and very low physical stress increase symptom frequency.

    Area of Science:

    • Occupational Health
    • Ergonomics
    • Public Health

    Background:

    • Modern industrial work increasingly involves physical monotony and inactivity.
    • Despite ergonomic improvements, locomotor system symptoms remain prevalent.
    • Reduced physical stress does not necessarily correlate with fewer physical complaints.

    Purpose of the Study:

    • To investigate the relationship between physical stress levels and musculoskeletal symptoms.
    • To explore the hypothesis of a U-shaped relationship between physical load and symptom frequency.
    • To identify optimal physical stress parameters for workplace design.

    Main Methods:

    • Analysis of recent studies examining physical stress and locomotor system symptoms.
    • Statistical modeling to identify relationships between physical activity levels and symptom occurrence.
    • Review of ergonomic workstation design impacts on physical load.

    Main Results:

    • A U-shaped relationship is observed between physical stress and symptom frequency.
    • High levels of physical stress are associated with increased symptoms.
    • Very low levels of physical stress are also linked to a higher frequency of symptoms.

    Conclusions:

    • Workplace physical stress may have both upper and lower acceptable limits.
    • Further research should investigate minimal variation in physical load.
    • Ergonomic interventions should consider the impact of reduced physical activity on musculoskeletal health.
