Gerontology·2026

Area of Science:

  • Gerontology
  • Biomechanics
  • Motor Control

Background:

  • Previous exercise interventions for falls prevention in older adults have yielded inconsistent results, potentially due to a lack of specificity.
  • Change-in-support (CIS) balance reactions, involving rapid limb movements, are crucial for preventing falls.
  • Age-related declines in CIS reactions contribute to increased fall risk.

Purpose of the Study:

  • To develop a perturbation-based balance training program targeting age-related deficits in CIS reactions.
  • To evaluate the efficacy of this novel training program in improving balance recovery and reducing fall risk in older adults.

Main Methods:

  • A 6-week program using unpredictable, multi-directional moving-platform perturbations to train stepping and grasping reactions.

Exergaming in Older People Living with HIV Improves Balance, Mobility and Ameliorates Some Aspects of Frailty

Published on: October 6, 2016

  • Incorporation of motor learning principles: individualization, specificity, overload, adaptation-progression, and variability.
  • A randomized controlled trial with 30 older adults (64-80 years) comparing perturbation-based training to flexibility/relaxation training, assessing CIS reactions pre- and post-intervention using platform and waist-pull perturbations.

    • Main Results:

    • The study protocol is designed to assess improvements in CIS reactions, including reduced multiple-step responses, fewer foot collisions, and faster grasping.
    • Generalizability of training effects will be evaluated using different perturbation methods.

    Conclusions:

    • This research will determine if perturbation-based balance training can reverse age-related impairments in balance recovery.
    • Findings aim to inform the development of more effective falls prevention strategies for older adults.
    • Successful outcomes could lead to reduced healthcare costs and improved mobility, independence, and quality of life.
