    Repetitive manual tasks significantly alter hand structure and function. Long-term textile workers showed task-specific changes in hand joints, demonstrating usage patterns influence hand anatomy and mobility.

    Area of Science:

    • Occupational health
    • Anatomy
    • Biomechanics

    Background:

    • Repetitive manual tasks are common in various occupations.
    • Understanding their impact on hand structure and function is crucial for worker health.
    • Previous studies have suggested a link, but specific task-related influences require detailed investigation.

    Purpose of the Study:

    • To investigate the influence of distinct, long-term manual task patterns on hand structure and function.
    • To compare structural and functional differences in hands of textile workers with different repetitive tasks.

    Main Methods:

    • Studied three groups of female textile workers with over 20 years in distinct, repetitive manual tasks.
    • Assessed range of motion, radiographic degenerative changes, digital joint malalignment, and osteophyte formation.

  • Compared right and left hand measures and analyzed task-specific differences.

    • Main Results:

    • Significant differences were observed between the right and left hands.
    • Highly significant task-related differences in hand structure and function were identified.
    • Observed changes in hand joints were consistent with the specific patterns of usage.

    Conclusions:

    • Specific patterns of repetitive manual usage significantly influence hand structure and function.
    • Occupational tasks can lead to measurable, task-dependent anatomical and functional adaptations in the hands.
    • Findings highlight the importance of considering task-specific ergonomics in occupational settings.
