The pattern of improvements for sway measures (RMS, MV, f95, ∆tc) and model parameters (KP, Kn, τd) for patients with PD, at four time points (i.e., pre-, week 2, week 4, and post-training) during the balance-training program, in tasks with stance on foam with eyes open (FO) and eyes closed (FC). Significant measures are in bold. Tukey P values are reported for post-hoc pairwise comparisons. The first time point, at which significant change appeared, and further time points, if that level of improvement retained, are marked with asterisk
