Objective: According to one of the hypotheses, somatoform disorders (SD) are related to disturbed perception of bodily signals. We suspect that the disturbances and abnormalities of multisensory integration dynamics may be an additional SD mechanism. The objective of the research was to investigate multisensory bodily illusion dynamics in SD patients. Methods: A clinical group of SD patients (n = 16) and a control group (n = 17) participated in experiments aimed at eliciting a visual-tactile rubber hand illusion (RHI) and a visual-kinesthetic virtual hand illusion (VHI). Results: For both illusions studied, the illusion dynamics in SD patients differed from those of healthy subjects. The visual-tactile illusion on the subjective level appeared to be less strong in SD patients, and no proprioceptive drift (PD) was detected. The subjective dynamics of the visual-kinesthetic illusion in patients were similar to those of the control group, but the PD dynamics were different: after the term
