“…The current paradigm may also have clinical usefulness. Conventional and virtual reality-based mirror visual feedback (MVF and VR-MVF) systems have been proposed among different methods to cure and release pain in patients with phantom limb, CRPS, and other chronic pain conditions [35][36][37][38]. The effectiveness of MVF therapy systems in alleviating the chronic pain severity is related to the restoration of the closed-loop between the motor command to the affected body part and its anticipated visual feedback [9,37].…”

The sense of agency (SoA) is part of psychophysiological modules related to the self. Disturbed SoA is found in several clinical conditions, hence understanding the neural correlates of the SoA is useful for the diagnosis and determining the proper treatment strategies. Although there are several neuroimaging studies on SoA, it is desirable to translate the knowledge to more accessible and inexpensive EEG-based biomarkers for the sake of applicability. However, SoA has not been widely investigated using EEG. To address this issue, we designed an EEG experiment on healthy adults (n = 15) to determine the sensitivity of EEG on the SoA paradigm using hand movement with parametrically delayed visual feedback. We calculated the power spectral density over the traditional EEG frequency bands for ten delay conditions relative to no delay condition. Independent component analysis and equivalent current dipole modeling were applied to address artifact rejection, volume conduction, and source localization to determine the effect of interest. The results revealed that the alpha and low-beta EEG power increased in the parieto-occipital regions in proportion to the reduced SoA reported by the subjects. We conclude that the parieto-occipital alpha and low-beta EEG power reflect the sense of agency.

“…Diving even further into the dangers VR can pose, it is possible to discuss the results a total virtual customization of needs and immediate personalized gratification might have [176]. The aftereffects of the persistent usage of VR can bring about a completely new field of research and the necessity for accompanying guidelines [177]. There are other risks that health intervention technologies might have that can be generally summarized as risks of addiction, stigmatization, isolation, bullying, or even risk of cultural issues that can pertain to the exposure in VR as well since the personal story representation should be considered very carefully with all of these factors in mind [178].…”

Reconstructing Personal Stories in Virtual Reality as a Mechanism to Recover the Self

Advances in virtual reality present opportunities to relive experiences in an immersive medium that can change the way we perceive our life stories, potentially shaping our realities for the better. This paper studies the role of virtual reality as a tool for the creation of stories with the concept of the self as a narrator and the life of the self as a storyline. The basis of the study is the philosophical notion of the self-narrative as an explanatory story of the events in one’s life that constitutes the notion of one’s self. This application is suitable for cases when individuals need to recreate their self, such as during recovery after traumatic events. The analysis of the effects of virtual reality shows that it enables a person to engage in a process of deeper self-observation to understand and explain adverse events and to give meaning to these events to form a new story, which can complement the therapeutic outcomes of exposure treatments. This study proposes concrete examples of immersive scenarios used to reconstruct personal stories. Several possible levels of experience are proposed to suggest that recovery can be achieved through the gradual retelling of the self-narrative, addressing all of the underlying narratives. Considering the ethical challenges that might arise, this paper explores the ways in which immersion in virtual reality can benefit a person’s view toward life as a story and his or her self as its author, comparing this idea with previous research on the application of virtual reality for trauma treatment. The analysis also emphasizes the perception of narrative authorship in virtual reality as an essential method for recovering the self-narrative and improving a patient’s mental health during self-actualization.

“…In this vein, studies applying virtual technologies to produce the illusory effect of one limb movement in amputees or post-stroke showed significant pain reduction as well as motor improvement after augmented 30,[35][36][37][38][39][40] 46 ). However, it must be considered that, due to their hardly suitable equipment, virtual MVF techniques are usually applied only in research settings and are scarcely adaptable to conventional home therapy 47 .…”
