Table 1: Observation summary on the ratio of VMO/VL muscle strength in walking and lifting legs/kicking legs at 30\({}^{\circ}\), 60\({}^{\circ}\), and 90\({}^{\circ}\). 0.481, 0.684 and 0.631, respectively, showing no statistically significant difference at \(\alpha\geq 0.05\). The box plot of pretest male and female left and right feet average in each mode of walking, lifting legs and kicking (30\({}^{\circ}\), 60\({}^{\circ}\), 90\({}^{\circ}\)) is shown in Figures 2 and 3. The purpose of the paired sample T test is to determine whether the average of the two related samples is significantly different or not. Compared with lift mode(30\({}^{\circ}\)/60\({}^{\circ}\)/90\({}^{\circ}\)), the walking mode of subjects were with the mean (M) of \(-0.168\), \(-0.186\), and \(-0.237\), the standard deviation SD = 0.111/0.179/0.168, T = \(-6.791\), \(-4.647\), and -6.336, and \(\alpha\leq 0.05\); when compared with kick mode, the walking mode of subjects were with the mean of \(-0.372/-0.419/-0.373\), the standard deviation (SD) of 0.173/0.172/0.152, T = \(-9.628\), \(-10.906\), and \(-11.007\), and \(\alpha\leq 0.05\). Since the leg-lifting of kicking action was significant (p \(<0.05\)) with respect to the walking pattern, there was a statistically significant difference. The results showed that the walking mode in accordance with the values listed in the reference was not statistically significant in difference. There was a significant difference between both the leg lift and kick leg mode and the walking mode, and the kicking mode had a greater difference than the leg lift mode. Overall, for each mode of walk contrasting leg raising and kicking (30\({}^{\circ}\), 60\({}^{\circ}\), 90\({}^{\circ}\)), subjects in the pretest had a better effect in the right foot than the left foot in each mode of walking. Moreover, the leg kicking had a better effect than the leg lifting, and the higher the angle in the leg lift mode, the higher the average value; in the kick mode, the average of 60\({}^{\circ}\) was better, and it might be because of 30\({}^{\circ}\) and 90\({}^{\circ}\) were not easy to kick; therefore, the subsequent rehabilitation actions would be based on the kicking action of the right foot as the main discussion target.
