During aging, motor function and cognitive function usually decline simultaneously. Motor disorders can be detected in the early stages of dementia and mild cognitive impairment (MCI). Previous studies indicated that finger movement characteristics are associated with cognitive decline. The purpose of this study was to explore the correlation between finger pressing force control and cognitive function using a novel hand training and evaluation system.
This study employed a novel hand training and evaluation system called Tipr, equipped with six loadcells. Tipr combines finger force control with an interactive "butterfly catching" game, with adjustable difficulty parameters. Nineteen elderly participants (age = 71.11 ± 4.16 years) participated in the Montreal Cognitive Assessment (MoCA) and the game test. The game difficulty ranged from level 1 to level 9. Correlation analysis was performed between success rates in games of different difficulty levels (Levels 3, 5, 7, and 9) and MoCA scores.
The results showed a significant negative correlation between age and MoCA scores (-0.508; p=0.026). The correlation coefficients between success rates at levels 3, 5, 7, and 9 and MoCA scores were -0.391, 0.226, 0.398, and 0.540, respectively. The correlation coefficients increased with increasing difficulty and were statistically significant only at level 9 (p=0.021), where the target appearance time in the game was shorter, and tolerance of force error was lower. These results showed that difficulty could influence discrimination rates. Hence, our findings suggest that finger force control assessment with appropriate parameters could potentially serve as an indicator for monitoring changes in cognitive function.
