Figure 3.

Results of the trials where participants tilted their heads sideways, with a focus on the variables representing the anterior–posterior movement of the body. The boxplots on top show the SaEn(COP_x) values as seen in Figure 2. The three graphs below represent the SaEn(PP_k) values of movement components substantially contributing to anterior–posterior postural movements. Significant differences are indicated (*). The bottom graph represents coordinative complexity characterized through rCUM(PP₅). No significant effects were observed in this data.
