The aim of the study was to evaluate movement time during a task at various levels of difficulty and to verify whether the level of difficulty affects the speed and/or accuracy during the task.
Multiple regression analysis indicated that age and motor performance assessed by the MFM-total scale can predict the increase in movement time from one ID to another.
The study also highlited a significant correlations between values ​​of r2 (a coefficient of determination that evaluates the degree of agreement between model predictions and the dependent variable) and the MFM-D3 score, indicating that the higher the distal functioning of the upper limbs, the lower the variability of the movement time.
