Note represents a significant difference in the change in dorsiflexion angle when compared to pre-intervention for within-group comparisons (p < 0.05); # represents a significant change in between-group comparisons with the Test group (p < 0.05); & represents a significant change in within-group comparisons after the first intervention and after the 4-week intervention (p < 0.05); M ± SD indicates mean ± standard deviation; PTFI = Post The First Intervention; P4WI = Post 4 Weeks Of Intervention
