* Asterisks indicate significant differences between some groups. LAT = laterality, DC = dynamic coordination, TPC = tonic postural control, ME = motor execution, BAL = balance, SUM = total score on the physical-motor factor, H = Kruskal-Wallis H test. SD = standard deviation, Me = median, G1 = skewness, and G2 = kurtosis.
