Postural sway in amputees and normal subjects

G R Fernie, P J Holliday

    The Journal of Bone and Joint Surgery. American Volume
    |October 1, 1978
    PubMed
    Summary

    Amputees rely more on vision to maintain balance. Those with below-the-knee amputations exhibit greater postural sway than those with above-the-knee amputations, with sway increasing with age.

    Area of Science:

    • Biomechanics
    • Human Physiology
    • Rehabilitation Science

    Background:

    • Postural sway is crucial for maintaining balance.
    • Amputation significantly impacts balance and mobility.
    • Understanding postural control in amputees is vital for effective rehabilitation.

    Purpose of the Study:

    • To quantitatively assess postural sway in individuals with lower-limb amputations.
    • To investigate the influence of amputation level (above-the-knee vs. below-the-knee) on postural control.
    • To determine the role of vision in maintaining balance for amputees and its relation to age.

    Main Methods:

    • Quantitative analysis of postural sway in 50 above-the-knee and 29 below-the-knee amputees.
    • Evaluation of sway speed, range of motion (sagittal and coronal planes), and visual dependence (eyes-open vs. eyes-closed).

    Main Results:

    • Amputees exhibit increased reliance on visual input for postural stability.
    • Postural sway is significantly greater in below-the-knee amputees compared to above-the-knee amputees.
    • Postural sway increases with age, but visual dependence remains constant across age groups.

    Conclusions:

    • Lower-limb amputation alters postural control mechanisms, increasing visual dependence.
    • The level of amputation influences the degree of postural instability.
    • Age affects postural sway but not the reliance on vision for balance in amputees.
