Sway measures for healthy control subjects (HCs) and PD patients before (PD-Pre) and after (PD-Post) balance training. a Root Mean Square (RMS), b Mean Velocity (MV), c The frequency up to which 95% of the total power frequency lies (f95), d Time coordinate for the critical point in the stabilogram diffusion function (SDF) diagram (∆tc). Left: ANOVA results comparing HCs and PD-Pre, †: Significant interaction (p < 0.05). Right: results of Tukey post hoc multiple comparisons between HCs and PD-Pre: * (p < 0.05). Bar charts also show paired sample t-test results between PD-Pre and PD-Post: • (p < 0.05), •• (p < 0.013)
