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.
