Note:

^1.Multiple comparisons (i.e., ANOVA + Tukey post hoc tests): for each column, each letter subscript represents a group within which there are no significant differences (p > 0.05); the subscripts in an alphabetical order were assigned to the groups with the means in an increasing order. Different subscripts mean significant differences between groups (p < 0.05).

^2.Student t-tests: the significant differences in the ROMs between the medial and lateral sides were indicated by bold.
