Demographic and clinical data of the individuals with spinal cord injury.
Figure 1.
Subjective rating of tactile sensation on the stimulated hand in the S
− group. Percentages indicate the strength of tactile sensation on each finger compared to the face and is represented as a gray scale from white (no sensation) to black (complete sensation, as on the face). The hands are sorted from the top left to the bottom right by the mean values, which are added to each hand numerically.
Figure 2.
A–C) Cambridge Depersonalization Scale (CDS) items with significant differences between the healthy subjects and the SCI patients A) Item 3 ‘Parts of my body feel as if they don't belong to me’; B) Item 27 ‘I have to touch myself to make sure that I have a body or a real existence’; C) Item 28 ‘I seem to have lost some bodily sensations (e.g. of hunger and thirst) so that when I eat or drink, it feels an automatic routine’.
Higher scores indicate increasing agreement with the statement. D) Significant correlation between the standard deviation of the proprioceptive judgment (i.e. accuracy in their baseline judgment) and the total CDS score.

Overview of the participants grouped according to the presence or absence of subjective (illusory ownership as measured by Q3 in the questionnaire) and objective (proprioceptive drift) measures of rubber hand illusion.

Significant interaction between group (SCI+, SCI-, healthy) and synchrony (synchronous, asynchronous stroking) for proprioceptive drift (mean ± SEM).
The values plotted are as compared to the baseline. * p<0.05.
