Figure 2. Effects of loading and unloading on group mean ±s.e.m. galvanic vestibular stimulation (GVS)-evoked reaction forces and frontal plane segment tilt.
In all panels the effects of loading are shown on the right and the effects of unloading are shown on the left. A, change in the rate of lateral horizontal force development 200–350 ms after stimulus onset. B, change in the rate of vertical force development 200–350 ms after stimulus onset. C, change in the rate of segment tilt 250–500 ms after stimulus onset. D, change in the rate of relative head-on-trunk and trunk-on-pelvis tilt 250–500 ms after stimulus onset.
