Figure 2:

Sample entropy (top figures) and entropic half-life (bottom figures) for the anterior-posterior and mediolateral directions of the COP beneath the prosthetic limb, intact limb and the combined COP for the individuals with transtibial amputation (TTA) and the matched individual limbs and the combined COP for the unimpaired individuals. Significant p-values of post hoc test from significant group-direction interaction are presented.
