Summary

Older adults at high risk of falls need more time for accurate sideways stepping adjustments. This difficulty in planning and executing movements may increase fall risk in this population.

Area of Science:

  • Biomechanics
  • Gerontology
  • Neuroscience

Background:

  • Falls are a significant health concern for older adults, with increased risk associated with age.
  • Stepping accuracy is crucial for navigating environments and avoiding obstacles.
  • Previous research suggests age-related declines in motor control, but specific deficits in stepping adjustments require further investigation.

Purpose of the Study:

  • To investigate age- and falls-risk related differences in the time required for accurate stepping.
  • To compare stepping performance between young adults, low-risk older adults, and high-risk older adults.
  • To analyze the effects of target presentation timing and location on stepping accuracy.

Main Methods:

  • Recruited three groups: young adults, low-risk older adults, and high-risk older adults (N=10 each).

  • Recorded eye and lower limb kinematics using eye-tracking and 3D motion analysis.
  • Manipulated stepping target timing (<1, 2, or 3s post-fixation) and location (central vs. lateral).
  • Main Results:

    • High-risk older adults required significantly more time for medio-lateral stepping adjustments compared to young and low-risk older adults.
    • Stepping performance varied based on target presentation timing and location across groups.
    • Reduced ability to make rapid sideways stepping adjustments was observed in high-risk older adults.

    Conclusions:

    • Older adults with a high risk of falling exhibit deficits in planning and executing sideways stepping adjustments.
    • This reduced capacity for rapid adjustments may contribute to an increased risk of trips and falls.
    • Potential neural mechanisms underlying these age- and falls-risk-related performance declines warrant further exploration.
