Overview

Analysis shows hand dexterity and mobility are key cognitive predictors in older adults, indicating practical evaluation methods.

Key Points

  • Poor hand dexterity and slower mobility tasks were linked to lower cognitive performance in older adults, with specific metrics demonstrating strong correlations.
  • The analysis explained 50.3% of the variance in cognition using a multi-domain approach that included various motor function assessments.
  • Stepwise regression identified both hand dexterity and functional mobility tasks as independent predictors, while other measures did not add significant value.
  • These findings highlight the importance of motor assessments like the Nine-Hole Peg Test and timed SPPB in cognitive aging research.
