Figure 3.
Bar charts with error bars of (a) median power frequency (MDF), (b) mean power frequency (MNF), and (c) peak power frequency (PKF) for the stroke group and the control group during the gait task. The bar charts represent the mean values, and the error bars show 95% confidence intervals (±95% C.I.) * (p < 0.05) indicates a significant difference (t-test).
