Underlined numbers are correlation coefficients higher than 0.40. n = 47. The data for participants who failed to reach the target during the trial (No Movement End = 64) or lacked any of the twelve parameters (n = 7) or who required any assistance in performing tasks 1, 2, 5, or 6 (n = 2) were excluded from data analysis
