Yet, studies addressing these aspects in EDs provided inconsistent results. Here, we simultaneously test ownership sense agency compared controls by exploiting different rubber hand illusion (RHI) paradigms (i.e., classic visuo-tactile, passive active visuo-motor versions). In any RHI versions, no differences susceptibility between patients emerged questionnaire, thus suggesting normal multisensory integration mechanism. Crucially, correlation analysis revealed that higher level dissatisfaction associated with increased RHI, as measured questionnaire. Interestingly, bulimic variant reported toward fake visuo-tactile revealing an abnormal absence voluntary movement. Moreover, exhibited proprioceptive drift both synchronous asynchronous conditions. Hence, our results dissociation explicit implicit measures, showing more plastic representation when enlists movements, leading stronger visual-capture proprioception. This study understanding intricate link agency, shedding light on role driving self EDs.
