Table 8: Wilcoxon right/left nonparametric test results—pairs/13–15 years (\(N=6\)). For the group of those over 15 years old, a series of values appear that are different from those found in the previously analyzed groups, even if, for most pairs, the right leg has higher scores, and in most cases there are still insignificant differences. A higher load is found for the rearfoot_left_load_percent and rearfoot_left_weight_ratio_percent, as well as higher values for total_left_Pmax. There is also a pair of data where statistically significant differences are reported: when loading the front of the foot (forefoot_left_load_percent and forefoot_right_load_percent), with a value of \(\left|\left.Z\right|=1.997\right.\), corresponding to a Sig. = 0.046. Understanding the differences between the values recorded for the dominant leg vs. the non-dominant one is made easier, due to the photos generated by the software for each case. The average values presented in the previous tables do not facilitate the formation of a complete image of the analyzed problem, and the selective presentation of the photographs for some of the measured parameters can be a source of complementary information.
