Older women exhibit greater gait instability and reduced velocity when walking and performing a cognitive task compared to younger women, increasing fall risk.

Area of Science:

Gerontology
Biomechanics
Neuroscience

Background:

Gait instability, indicated by stride velocity variability, predicts falls in older adults.
Dual-task walking (walking while performing a cognitive task) increases fall risk, especially in older individuals.
Stride velocity variability during dual-task walking may differ between age groups.

Purpose of the Study:

To investigate age-related differences in gait velocity and stride velocity variability during dual-task walking.
To compare gait parameters between older and younger community-dwelling women under single and dual-task conditions.

Main Methods:

Twenty-three older (80 ± 9 years) and 19 younger (23 ± 2 years) women participated.
Participants walked under two conditions: self-selected velocity and self-selected velocity with backward counting.

Gait velocity and stride velocity variability were measured using GAITRite instrumentation.

Main Results:

Both groups showed decreased gait velocity and increased stride velocity variability during dual-task walking.
Older women demonstrated a greater relative reduction in gait velocity compared to younger women.
Older women exhibited a larger magnitude of stride velocity variability during dual-task walking.

Conclusions:

Dual-task walking conditions destabilize gait in both younger and older women.
Cognitively demanding tasks during walking significantly impact gait stability.
These findings suggest older adults are at a higher risk of falls during cognitively demanding walking tasks.
