Slower walking speed when performing a secondary task, like counting backward, is linked to recurrent falls in frail older adults. This simple gait assessment may help identify those at higher risk.

Area of Science:

  • Gerontology
  • Biomechanics
  • Public Health

Background:

  • Falls are a major concern for frail older adults, leading to injury and loss of independence.
  • Gait performance, particularly under dual-task conditions, is increasingly recognized as a predictor of falls.

Purpose of the Study:

  • To investigate the association between dual-task related changes in walking speed and recurrent falls in frail older adults.
  • To identify simple, inexpensive methods for fall risk assessment in this population.

Main Methods:

  • A 12-month prospective cohort study involving 213 frail older adults (mean age 84.4).
  • Baseline assessment of usual and dual-task (walking while counting backward) walking speeds.
  • Monthly collection of fall data to identify recurrent fallers (>=2 falls).

Main Results:

  • Slower walking speed during dual-tasking was significantly associated with recurrent falls (Incident Rate Ratio=0.84, P=.045).
  • Age and number of medications were also associated with falls in crude analyses.
  • Dual-task walking speed and number of drugs remained significant predictors in multiple regression.

Conclusions:

  • Reduced gait speed during dual-tasking is a significant predictor of recurrent falls in frail older adults.
  • Assessing gait performance under dual-task conditions offers a potentially valuable and inexpensive method for fall risk stratification.
