Older adults performing backward counting (CB) while walking showed varied results. A small group improved gait and counting, suggesting a "magnet effect" strategy, while most experienced performance decline.

Area of Science:

  • Gerontology
  • Neuroscience
  • Biomechanics

Background:

  • Rhythmic tasks like backward counting (CB) and walking can interact.
  • The

Purpose of the Study:

  • To investigate how dual-tasking (CB while walking) affects gait variability (CoV of ST) and cognitive performance in older adults.
  • To compare older adults who decreased their CoV of ST with those who increased it during dual-tasking.

Main Methods:

  • 100 community-dwelling older adults performed single-task (CB sitting/walking) and dual-task (CB walking) assessments.
  • Measured coefficient of variation (CoV) of stride time (ST) and number of enumerated figures.
  • Participants categorized into groups based on changes in CoV of ST during dual-tasking.

Main Results:

  • Most participants showed worsened gait and CB performance during dual-tasking.
  • A subset (17%) decreased CoV of ST, indicating improved gait stability, and tended to enumerate more figures.
  • This improvement was linked to higher baseline gait variability and potentially the "magnet effect".

Conclusions:

  • Dual-tasking typically impairs gait and cognitive performance in older adults.
  • A subgroup with high gait variability may utilize the "magnet effect" to enhance gait and cognitive function simultaneously.
  • This suggests an implicit strategy for managing dual-tasking in specific older adult populations.
