Distinct patterns of visuo-tactile and visuo-motor body-related integration in Parkinson's disease.

ABSTRACT: Multisensory integration (MSI) deficits in patients with Parkinson's Disease (PD) have recently attracted growing interest in both clinical and research realms, MSI being crucial in maintaining well-coordinated responses to external stimuli. In this framework, we exploited the Rubber Hand Illusion (RHI), an experimental procedure that induces healthy individuals to embody a fake hand by integrating multisensory body-related cues, to address potential alterations of the embodiment phenomenon in PD. Specifically, we leveraged a visuo-tactile (VT; Experiment 1) and a visuo-motor (VM; Experiment 2) RHI version and applied it to 32 PD patients and age-matched controls. Classical RHI measures (i.e., ownership and agency questionnaires, proprioceptive drift) were collected. Questionnaires reveale
