M = mean, SD = standard deviation, Md = Median, IQR = Inter quartile range. N = 21.
Fig 2.
Boxplots of aggregated body perception indices (BPI; estimated/actual length * 100) for the left and right body side at baseline, under vestibular stimulation and at sham/post-assessment. BPI > 100 indicates overestimation, BPI < 100 indicates underestimation. There was no significant change in BPI due to vestibular stimulation in any of the experiments. Experiment 1 (left anodal subthreshold galvanic vestibular stimulation; GVS) is depicted in the top row; experiment 2 (left caloric vestibular stimulation with cold water; CVS) is depicted in the bottom row.
Table 2.
Means (M) and standard deviations (SD) for the aggregated body perception index (BPI; estimated/actual length * 100) in each experimental condition.
BPI > 100 indicates overestimation, BPI < 100 indicates underestimation. GVS = left anodal subthreshold galvanic vestibular stimulation; CVS = caloric vestibular stimulation (cold water irrigation to the left auditory canal).
