Primary Institution: Texas A&M University
Hypothesis
The study investigates the mediating role of cortico-striatal resting-state functional connectivity in the relationship between dual-tasking and gait in older adults.
Conclusion
The study found no significant relationship between dual-task performance and gait measures.
Supporting Evidence
- The study involved a set shifting task where participants had to verbalize numbers or letters based on background color.
- fMRI was used to analyze cortico-striatal connectivity.
- Results showed no significant direct effect of dual-task on gait measures.
Takeaway
The study looked at how brain connections affect walking while doing two things at once, but found that they don't seem to be related.
Methodology
Five older adults completed a set shifting task while standing and walking, followed by fMRI to analyze brain connectivity.
Limitations
The small sample size limits the generalizability of the findings.
Participant Demographics
Older adults
