From: Self-selected gait speed - over ground versus self-paced treadmill walking, a solution for a paradox

Figure 3

Self- selected gait speed as function of the distance covered while walking on SP TM. Gait speed was averaged over each meter walked for each subject, and group grand average is plotted (gray dots). The SD (±) of this average is represented by the shaded light gray area on both sides of the curve. The black short overlapping curves highlight gait speed values during the 10 m segments (TMS1, TMS2, TMS3, TMS4) which are analogous to four consecutive tests of the over ground 10MWT. Dashed horizontal lines in each panel represent the mean over-ground gait speed, 1.50 ± 0.13 m/s. A. Data from EXPERIMENT A – self- paced treadmill without the presence of the visual virtual reality scenery. B. Data from EXPERIMENT B – self- paced treadmill with the presence of the visual virtual reality scenery. While post hoc comparisons (Bonferroni corrected) yielded no significant difference between TMS3 and TMS4 and GS, mean values of TMS3 and TMS4 showed tendency to be as compared to GS (uncorrected paired t-test; p = 0.058, p = 0.038, respectively). TM- treadmill; VR- virtual reality.
