Figure 3

Mean values for RMS roll, pitch, and tilt, as well as percentage of time with tilt less than the low threshold (Null) and less than the high threshold (Null+Low) for each of the four tasks (slow-paced and self-paced walking, walking on a narrow surface, and walking on foam). Error bars indicate ±1 standard error of the mean. Displays with no feedback (N), continuous feedback (C), and gated feedback (G) were used for slow-paced and self-paced tasks. Narrow and foam surfaces were tested without feedback both before (N1) and after (N2) feedback trials. Statistical comparisons were made between the initial baseline values (N or N1) and the other displays (C, G, or N2). Significant effects are indicated for p < .05 (*) and p < .01 (#).
