[Gait in the aged (author's transl)].

J U Baumann

    Aktuelle Gerontologie
    |November 1, 1980
    PubMed
    Summary
    This summary is machine-generated.

    Older adults exhibit altered gait due to decreased muscle elasticity and joint mobility, resulting in slower walking speeds. A key finding is the irregular frontal forces in older individuals, impacting gait stability.

    Area of Science:

    • Biomechanics
    • Gerontology
    • Kinesiology

    Context:

    • Aging is associated with physiological changes affecting motor control.
    • Gait analysis is crucial for understanding age-related mobility decline.
    • Previous research highlights reduced walking speed and altered gait parameters in older adults.

    Purpose:

    • To compare gait dynamics, specifically floor reaction forces, between a young and a very old adult.
    • To identify biomechanical differences contributing to age-related gait impairments.

    Summary:

    • Gait changes in older individuals stem from reduced muscle/ligament elasticity, joint mobility, and equilibrium.
    • These changes manifest as slower walking speeds and an increased double-stance phase.
    • Analysis of floor reaction forces revealed significant instability in the older adult, particularly in frontal forces crucial for stabilization.
