Hypothesis
Is intraindividual variability in cognitive performance associated with mobility in individuals who have experienced a stroke?
Conclusion
Higher intraindividual variability in cognitive performance is associated with worse mobility in adults who have had a stroke.
Supporting Evidence
- Higher intraindividual variability represents reduced consistency in cognitive responses.
- Intraindividual variability may be a more sensitive measure of cognitive performance than traditional scores.
- Mobility was assessed using timed up and go (TUG) performance.
Takeaway
This study found that people who have had a stroke and show more inconsistency in their thinking may also have more trouble moving around.
Methodology
The study used baseline data from a six-month single-blinded, 3-group parallel randomized controlled trial.
Limitations
The effects were not found when age was included as a covariate.
Participant Demographics
Community-dwelling adults with a history of stroke, aged 55 years and older, with a mean age of 70.71 years.
