“…The RHI has been used to investigate the link between internal representation of the body and various autonomic indices. Synchronous stroking has been reported to decrease participants’ real hand skin temperature ( Llobera et al, 2013 , Moseley et al, 2008 , Tieri et al, 2018 , Tsakiris et al, 2011 ), even though the consistency of such finding is currently not confirmed by other studies ( de Haan et al, 2017 , Rohde et al, 2013 ) ( Lang et al, 2021 ; Roel Lesur, Weijs et al, 2020 ). Furthermore, an increase of histamine reactivity was also observed by comparing wheal dimension after histamine injection on the tested and contralateral arm ( Barnsley et al, 2011 ).…”

“…Similar ndings were obtained in other studies [8][9][10] . However, many other studies found no modulation of the real hand temperature during the RHI [11][12][13][14][15] . Since reports on the hand temperature change during the RHI seemed inconsistent, it was important to clarify whether a physiological change such as decreased hand temperature was a suitable biomarker for the illusion strength.…”

The neural representation of the body is easily altered by integrating multiple sensory signals in the brain. The “rubber hand illusion” (RHI) is one of the most popular experimental paradigms to investigate this phenomenon. During this illusion, ownership of a rubber hand is created. It was shown that external and continuous cooling of the palm enhanced the RHI, suggesting an association between disrupting the autonomic nervous system regulation and disrupting the sense of ownership of a specific limb. However, the effects of artificially cooling the entire hand for a short period on the magnitude of the illusion remain unknown. Here we show that cooling the hand by immersing it in water for 1 min enhanced the RHI strength. We found that cooling the entire hand enhanced the proprioceptive drift during the RHI but not the subjective feeling of ownership. In contrast, warming and intense cooling of the entire hand did not affect the RHI strength. Our results suggest that transient and moderate cooling of the entire hand was sufficient in enhancing the illusory disembodiment of one’s own hand.

The term embodiment has become omnipresent within prosthetics research and is often used as a metric of the progress made in prosthetic technologies, as well as a hallmark for user acceptance. However, despite the frequent use of the term, the concept of prosthetic embodiment is often left undefined or described incongruently, sometimes even within the same article. This terminological ambiguity complicates the comparison of studies using embodiment as a metric of success, which in turn hinders the advancement of prosthetics research. To resolve these terminological ambiguities, we systematically reviewed the used definitions of embodiment in the prosthetics literature. We performed a thematic analysis of the definitions and found that embodiment is often conceptualized in either of two frameworks based on body representations or experimental phenomenology. We concluded that treating prosthetic embodiment within an experimental phenomenological framework as the combination of ownership and agency allows for embodiment to be a quantifiable metric for use in translational research. To provide a common reference and guidance on how to best assess ownership and agency, we conducted a second systematic review, analyzing experiments and measures involving ownership and agency. Together, we highlight a pragmatic definition of prosthetic embodiment as the combination of ownership and agency, and in an accompanying article, we provide a perspective on a multi-dimensional framework for prosthetic embodiment. Here, we concluded by providing recommendations on metrics that allow for outcome comparisons between studies, thereby creating a common reference for further discussions within prosthetics research.
