Why the study?
Do stress and gender affect prefrontal cortex oxygenation levels and stride velocity during single and dual-task walking conditions in older adults?
Population
Community residing older adults, mean age 76.8 ± 6.7 years, 56% female.
Design
Cross-sectional
Key result
Higher perceived stress in older men was associated with a greater decline in stride velocity and an attenuated increase in prefrontal cortex oxygenation during dual-task walking.

Perceived stress may impair dual-task gait in older men; cross-sectional data leave open causality and need prospective confirmation before clinical consideration.

Do stress and gender affect prefrontal cortex oxygenation levels and stride velocity during single and dual-task walking conditions in older adults?
Older men may be more vulnerable to the effects of perceived stress on prefrontal cortex oxygenation and stride velocity during cognitively demanding walking tasks.
Holtzer et al. (2016) conducted a cross-sectional in Community residing older adults. Perceived stress vs. Low perceived stress was evaluated on Stride velocity and PFC Oxygenated Hemoglobin (HbO2) during single and dual-task walking conditions. Higher perceived stress in older men was associated with a greater decline in stride velocity and an attenuated increase in prefrontal cortex oxygenation during dual-task walking.
