Hypothesis
This study aims to map functional networks associated with physical reserve and examine the relationship between physical reserve, white matter hyperintensities, and postural balance.
Conclusion
Higher physical reserve helps maintain postural balance despite the presence of white matter lesions.
Supporting Evidence
- Physical reserve was defined as the unexplained variance in Timed-Up-and-Go test results.
- Functional neural networks were identified using general linear models.
- High physical reserve was associated with maintained postural balance despite white matter lesions.
Takeaway
Older adults with better physical reserve can stay balanced even if they have brain issues.
Methodology
The study used a cross-sectional design and analyzed the Timed-Up-and-Go test results along with brain imaging data.
Participant Demographics
Community-dwelling older adults with subcortical ischemic vascular cognitive impairment.
