“…It actually even partially supported the rationale underlying our study, that is, eliciting a strong SOO would enhance 3PP MI. Here, we proposed achieving this through a synchronous visuo-tactile stimulus previously validated to be effective [38]. Our experiment demonstrated that this method can indeed elicit the SOO to the virtual avatar for most participants, and the SOO elicitation further enhanced the 3PP MI.…”

“…Stroke patients experienced embodiment and presence similar to the healthy [31]. Therefore, the multisensory integration in stroke patients may remain intact or at least partially preserved, providing the basis for a successful induction of such an illusion in stroke patients [31], [38]. Studies also showed that the body ownership of moving objects can be induced on motionless participants [78], [79].…”

“…The "OBE" FBI has been successfully induced in healthy individuals by Ehrsson et al and Lenggenhager et al through a synchronous visuo-tactile stimulus to a virtual avatar placed 2 m in front of their physical bodies [34], [35]. In stroke patients, the neural pathways involved in the SOO formation may remain intact or partially preserved [31] because the SOO can successfully be elicited by a synchronous visuo-tactile stimulus [36], [37], [38].…”

Virtual reality (VR)-based rehabilitation training holds great potential for post-stroke motor recovery.Existing VR-based motor imagery (MI) paradigms mostly focus on the first-person perspective, and the benefit of the third-person perspective (3PP) remains to be further exploited. The 3PP is advantageous for movements involving the back or those with a large range because of its field coverage. Some movements are easier to imagine from the 3PP. However, the 3PP training efficiency may be unsatisfactory, which may be attributed to the difficulty encountered when generating a strong sense of ownership (SOO). In this work, we attempt to enhance a visualguided 3PP MI in stroke patients by eliciting the SOO over a virtual avatar with VR. We propose to achieve this Manuscript

Visual guided motor imagery (MI) is commonly used in stroke rehabilitation, eliciting event-related desynchronization (ERD) in EEG. Previous studies found that immersion level and visuo-tactile stimulation could modulate ERD during visual guided MI, and both of two factors could also improve sense of ownership (SOO) over target limb (or body). Additionally, the relationship was also reported between the performance of MI and SOO. This study aims to investigate whether immersion and visuo-tactile stimulation affect visual guided MI through the SOO over virtual body in stroke patients. Nineteen stroke patients were recruited. The experiment included two phases (i.e., SOO induction and visual guided MI with SOO) that was manipulated across four conditions in a within-subject design: 2×2, i.e., immersion (VR, 2D monitor display) × multisensory stimulation (visuo-tactile stimulation, observation without tactile stimulation). Results found peaks ERD amplitude during MI were significantly higher in stronger SOO conditions than weaker SOO conditions. Interestingly, the ERD during visual guided MI under the condition of vision only in VR and visuo-tactile stimulation in 2D monitor are similar, which indicates that SOO may be an important factor behind this phenomenon (due to the similar SOO between these two conditions). A moderate correlation was also found between SOO scores and peaks ERD amplitude during MI. This study discussed the possible factor underlying the effects of immersion and multisensory stimulation on visual guided MI in post-stroke patients, identifying the effect of SOO in this process, and could be referred in future studies for coming up with better MI paradigms for stroke rehabilitation.
