Figures & data
Figure 1. Both control (CO) group and action observation (AO) group received verbal explanation before starting the experiment task. In addition to the verbal explanation, AO group watched a video of another person performing the same task (observation period). The non-weight-bearing (NWB) gait showed a third-person perspective of the entire body from the front, back, right, and left sides in the video. All participants were performed a total of 10 trials. The interval between trials was set to 30 s or more. Gait speed and trunk acceleration were measured during the 1st, 5th, and 10th trials for each group.
Figure 2. (a) Gait speed in the 1st, 5th, and 10th trials. Two-way ANOVA revealed a main effect of trial (p < 0.05), but no effect of group (p > 0.05) and interaction (p > 0.05). (b) Acceleration root mean square (RMS) in the 1st, 5th, and 10th trials. The two-way ANOVA also revealed a main effect of trial (p < 0.05), group (p < 0.05), as well as trial and group interaction (p < 0.05). Post hoc analysis further showed significant differences in acceleration RMS (p < 0.05) between the control (CON) and action observation (AO) groups during the 1st trial.
