Figure 5.

Power modulation during stepping while standing resembles the modulation during sitting. A, The increase in beta power after the contralateral step during stepping while standing (right) looks very similar to the modulation while sitting (left; n = 6 STN; compare Fig. 3). B, The 20–30 Hz power average (line plot) shows a similar alternating pattern to that in Figure 4. C, Beta modulation in both hemispheres and both tasks from one example patient (P11). D, The degree of modulation during stepping while standing closely correlates with the degree of modulation while sitting across the six recorded STN.
