Ergonomics and cumulative trauma disorders.

T J Armstrong

    Hand Clinics

    Summary

    Occupational hand-intensive work can cause chronic upper extremity disorders like tendinitis. Identifying and controlling risk factors such as repetitiveness, force, and poor posture in work design can prevent these common injuries.

    Area of Science:

    • Occupational health
    • Ergonomics
    • Musculoskeletal disorders

    Background:

    • Chronic tendon and nerve disorders of the upper extremity are prevalent in individuals performing hand-intensive tasks.
    • Conditions like tendinitis and carpal tunnel syndrome significantly impact worker health and productivity.

    Purpose of the Study:

    • To summarize common occupational risk factors associated with upper extremity disorders.
    • To provide guidance on identifying and controlling these risk factors through work equipment and procedure design.

    Main Methods:

    • Literature review and synthesis of commonly reported occupational risk factors.
    • Analysis of risk factors including repetitiveness, forcefulness, postures, mechanical stresses, vibration, and low temperatures.
    • Discussion of methods for identifying and controlling identified risk factors.

    Main Results:

    • Repetitiveness, forcefulness, awkward postures, mechanical stresses, vibration, and low temperatures are key occupational risk factors.
    • Effective control strategies involve redesigning work equipment and procedures.
    • Proactive identification and mitigation of these factors are crucial for prevention.

    Conclusions:

    • Implementing ergonomic principles in work design is essential for preventing chronic upper extremity disorders.
    • Controlling occupational risk factors can reduce the incidence of tendinitis and carpal tunnel syndrome.
    • Workplace interventions focused on equipment and procedures can mitigate hazards associated with hand-intensive work.
