The Conventional Non-Articulated SACH or a Multiaxial Prosthetic Foot for Hypomobile Transtibial Amputees? A Clinical Comparison on Mobility, Balance, and Quality of Life

Figure 4

Box-plots for the nine subscales scores of the Prosthesis Evaluation Questionnaire (PEQ). The boxes show the lower quartile, median (bold line), and upper quartile values, the whiskers represent the most extreme values within 1.5 times the interquartile range from the ends of the box, and the circles represent the outliers (data with values beyond the ends of the whiskers). The ordinal data of the nine functional scales of PEQ have been compared between P1 and P2 using Wilcoxon signed rank test.
