Changes in high-order interaction measures of synergy and redundancy during non-ordinary states of consciousness induced by meditation, hypnosis, and auto-induced cognitive trance

NeuroImage, Journal Year: 2024, Volume and Issue: 293, P. 120623 - 120623

High-order interactions are required across brain regions to accomplish specific cognitive functions. These functional interdependencies reflected by synergistic information that can be obtained combining the from all sources considered and redundant (i.e., common provided sources). However, electroencephalogram (EEG) connectivity is limited pairwise thereby precluding estimation of high-order interactions. In this multicentric study, we used measures study in parallel between five EEG electrodes during three non-ordinary states consciousness (NSCs): Rajyoga meditation (RM), hypnosis, auto-induced trance (AICT). We analyzed data 22 long-term meditators, nine volunteers undergoing 21 practitioners AICT. here report within-group changes synergy redundancy for each NSC comparison with their respective baseline. During RM, increased at whole level delta theta bands. Redundancy decreased frontal, right central, posterior delta, beta1 beta2 mid-frontal, temporal, mid-centro-parietal band. The decrease was also observed band left frontal parietal electrodes. AICT, bands left-frontal, right-frontocentral, alpha hypnosis AICT were not significant. subjective reports absorption dissociation as well mystical experience questionnaires showed no correlation measures. proposed first exploratory attempt utilize concepts NSCs. differences different NSCs warrant further studies relate extracted phenomenology

Virtual reality hypnosis in the management of pain: Self‐reported and neurophysiological measures in healthy subjects

European Journal of Pain, Journal Year: 2022, Volume and Issue: 27(1), P. 148 - 162

Published: Oct. 5, 2022

Virtual reality hypnosis (VRH) has emerged as a new and promising option for pain management. Nonetheless, neural dynamics of modulation during VRH have not been investigated yet. The aim this study was to measure the effects on pain, combining neurophysiological self-reported measurements.

Virtual reality in functional neurological disorder: a theoretical framework and research agenda for use in the real world

BMJ Neurology Open, Journal Year: 2024, Volume and Issue: 6(2), P. e000622 - e000622

Functional neurological disorder (FND) is a common and disabling condition at the intersection of neurology psychiatry. Despite remarkable progress over recent decades, mechanisms FND are still poorly understood there limited diagnostic tools effective treatments. One potentially promising treatment modality for virtual reality (VR), which has been increasingly applied to broad range conditions, including neuropsychiatric disorders. unique features, many suggest particular relevance for, potential efficacy of, VR in both better understanding managing disorder. In this review, we describe how might be leveraged diagnosis (with primary focus on motor persistent perceptual-postural dizziness given their prominence literature), as well elucidation neurocognitive symptom phenomenology. First, review what published date applications related We then discuss hypothesised mechanism(s) underlying FND, focusing features that most relevant applications.

Virtual reality hypnosis prior to radiofrequency thermocoagulation for patients with chronic pain: an exploratory clinical trial

Frontiers in Psychology, Journal Year: 2024, Volume and Issue: 15

Published: Feb. 27, 2024

Background The management of chronic pain may involve an array tools, including radiofrequency thermocoagulation (Rf-Tc) sensory nerve terminals. Like many other invasive procedures, Rf-Tc can generate anxiety in a lot patients, either during the expectation procedure or course it. Virtual reality hypnosis (VRH) is promising tool for managing and several situations, but its anxiolytic property has not been investigated participants with going through procedure. Objectives goal this study was to evaluate effectiveness VRH reducing self-assessed pain, when received preparation Rf-Tc. Materials methods This prospective, controlled trial conducted Interdisciplinary Algology Centre University Hospital Liège (Belgium). Participants were assigned two groups: control (usual care). Assessment carried-out at 4 time points: T0 (one week before Rf-Tc); T1 (pre-intervention, on day T2 (immediately after intervention outside room); T3 (right Rf-Tc). Medical, sociodemographic data, trait immersive tendencies collected T0. Anxiety state intensity assessed each points. Satisfaction examined T3. Results Forty-two quasi-randomly group. No statistically significant interaction group by observed regarding all measured variables, primary endpoint. However, effect found considering both groups together, toward progressive reduction. Conclusion In context our study, there appears be no undergoing decreases along procedure, while attenuated local anesthetic infiltration Rf site. Our results suggest that presence caregiver throughout might explain decrease anxiety. Future randomized trials are needed precisely tool, possibility using it as complementary approach procedures.

Mapping Knowledge Landscapes and Evolving Trends of Clinical Hypnotherapy Practice: A Bibliometrics-Based Visualization Analysis

International Journal of General Medicine, Journal Year: 2024, Volume and Issue: Volume 17, P. 5773 - 5792

Published: Dec. 1, 2024

Background and Aims: Increasing interest in hypnotherapy's application for a wide range of health conditions has spurred rise global research publications. This study aims to visualize development patterns current hotspots clinical hypnotherapy practice using scientometric methods, predict future directions based on the keyword trending topics analysis. Methods: Data applications mechanisms settings between 1994 2023 were gathered from Scopus, Web Science, PubMed, followed by analysis visualization VOSviewer, Bibliometrix package R , CiteSpace. Results: A total 1,549 publications examined, indicating steady annual increase with an average growth rate 8.5%, reaching high 134 2022. The United States was primary hub. Collectively, 1,464 distinct institutions involving 3,195 scholars contributed this theme. Collaboration predominantly confined same country, institution, and/or team. High-frequency keywords included "Pain", "Irritable Bowel Syndrome (IBS)", "Anxiety". Systematic review meta-analysis have emerged as favored methods. fMRI EEG commonly used techniques exploring neuropsychological underlying hypnotherapy.

Myofascial pain syndrome (MPS) is a highly prevalent and burdensome cause of globally, representing major focus chronic management. Management MPS variable, with therapies ranging from interventional approaches to physical therapy. Virtual reality (VR) novel form therapy being actively explored as an adjuvant procedural sedation in the acute setting, increasingly means management through programs that facilitate education, mindfulness, among other approaches. However, date, there are minimal clinical studies assessing VR within context treatments. Given existing volume work published setting translational exploring neuroplasticity pain, we make case here it appropriate time consider non-pharmacological treatment for MPS.

Virtual Reality Combined with Mind-Body Therapies for the Management of Pain: A Scoping Review

International Journal of Clinical and Experimental Hypnosis, Journal Year: 2024, Volume and Issue: unknown, P. 1 - 37

Published: Sept. 30, 2024

When used separately, virtual reality (VR) and mind-body therapies (MBTs) have the potential to reduce pain across various acute chronic conditions. While their combination is increasingly used, no study offers a consolidated presentation of VR MBTs. This aims propose an overview effectiveness combined with MBTs (i.e., meditation, mindfulness, relaxation, hypnosis) decrease experienced by healthy volunteers or patients. We conducted scoping review literature using PubMed, Science Direct Google Scholar included 43 studies. Findings studies support that feasible, well-tolerated, potentially useful pain. Their also had positive effect on anxiety, mood, relaxation. However, insufficient research this VR/MBTs lack multidimensional impede comprehensive understanding full potential. More randomized controlled are thus needed, usability evaluation protocols better understand effects patients wellbeing incorporate them into routine clinical practice.
