Figure 5
Regression slopes of trunk versus pelvis movements of a BVL subject standing eyes closed on foam with and without feedback. Regression slopes after low-pass filtering (LP) and band-pass filtering (BP) of trunk and pelvis sway angle traces are shown. The upper panel shows the slopes without biofeedback, the lower ones with feedback. On the left are the low pass regressions, on the right the band-pass regressions.
