Postural control and posture-unrelated attention control in advanced age-An exploratory study

Area of Science:

• Gerontology
• Neuroscience
• Biomechanics

Background:

• The relationship between cognitive function and postural control in older adults is not well understood.
• Investigating posture-unrelated attention control offers insights into maintaining balance in aging populations.

Purpose of the Study:

• To examine the association between postural control and posture-unrelated attention control in healthy older adults.
• To explore potential gender differences in this relationship.

Main Methods:

• Cross-sectional study of 112 healthy older adults (men and two groups of women).
• Postural control assessed via static balance (SB) and dynamic balance (DB) tests (Timed Up-and-Go, Functional Reach Test).
• Attention control (inhibition) measured using the Continuous Performance Test (Go/NoGo tasks with and without distractors).

Main Results:

• Men showed better dynamic balance, while women excelled in static balance.
• Significant correlations between attention tasks and dynamic balance in men.
• Attention tasks correlated with static balance in younger women, but not older women.
• Attention tasks without distractors, and with audio distractors, explained postural control variability.

Conclusions:

• Posture-unrelated attention inhibition is linked to static balance in women and dynamic balance in men.
• Cognitive tasks without distractions are key predictors of postural control across genders.
• Further research on balance exercises and their impact on both cognitive and postural control is recommended for fall prevention.
