Force wave transmission through the human locomotor system

A Voloshin, J Wosk, M Brull

    Journal of Biomechanical Engineering
    |February 1, 1981
    PubMed
    Summary

    Healthy individuals have superior shock absorption in their locomotor system compared to those with joint disorders. Degenerative joint changes impair shock absorption, potentially leading to osteoarthritis due to system overloading.

    Area of Science:

    • Biomechanics
    • Human Locomotion
    • Musculoskeletal Health

    Background:

    • The human body possesses a natural shock absorber system to mitigate dynamic loading during movement.
    • Understanding the efficiency of this system is crucial for diagnosing and managing musculoskeletal conditions.

    Purpose of the Study:

    • To present a method for measuring the shock-absorbing capacity of the human locomotor system during gait.
    • To compare the shock attenuation capabilities between healthy individuals and those with pathological joint conditions.

    Main Methods:

    • Experiments were conducted involving two groups: healthy subjects and subjects with various pathological conditions.
    • The study measured the capability of the human shock absorber system to attenuate dynamic loading during gait.

    Main Results:

    • A significant difference in shock-absorbing capability was observed between the two groups.
    • Healthy subjects demonstrated a more efficient shock-absorbing capacity than subjects with joint disorders.
    • Degenerative changes in joints were found to reduce shock absorption, leading to increased load on subsequent components of the locomotor system.

    Conclusions:

    • Joint disorders and degenerative changes diminish the body's natural shock absorption.
    • Overloading of the locomotor system's shock absorbers due to impaired joint function may contribute to the development of osteoarthritis.
