Jones HG, Rizzo RRN, Pulling BW, Braithwaite FA, Grant AR, McAuley JH, Jensen MP, Moseley GL, Rees A, Stanton TR. Adjunctive use of hypnosis for clinical pain: a systematic review and meta-analysis. Pain Rep 2024; 9:e1185. [PMID: 39263007 PMCID: PMC11390056 DOI: 10.1097/pr9.0000000000001185] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2023] [Revised: 06/17/2024] [Accepted: 07/12/2024] [Indexed: 09/13/2024] Open
Abstract
Systematic reviews suggest that stand-alone hypnotic suggestions may improve pain outcomes compared with no treatment, waitlist, or usual care. However, in clinical practice, hypnosis is often provided adjunctively with other interventions, which might have different effects than those reported in previous reviews. This systematic review aimed to summarize the analgesic effects of adjunctive hypnosis in adults with clinical pain. Seven databases (MEDLINE, Embase, PsycINFO, Emcare, SCOPUS, CENTRAL, Cochrane) were searched up to January 2024. Randomised controlled trials comparing the analgesic effects of adjunctive hypnosis (hypnosis + primary intervention) with those of the primary intervention alone were included. Meta-analyses (random-effects model) calculated mean differences (MD, [95% confidence intervals]) for pain intensity (0-100). Seventy studies were pooled in meta-analyses (n = 6078). Hypnosis adjunctive to usual care had a small additional analgesic effect (chronic pain: -8.2 [-11.8, -1.9]; medical procedures/surgical pain: -6.9 [-10.4, -3.3]; burn wound care: -8.8 [-13.8, -3.9]). Hypnosis adjunctive to education had a medium additional analgesic effect for chronic pain (-11.5 [-19.7, 3.3]) but not postsurgery pain (-2.0 [-7.8, 3.7]). When paired with psychological interventions, hypnosis slightly increased analgesia in chronic pain only at the three-month follow-up (-2 [-3.7, -0.3]). Hypnosis adjunctive to medicines had a medium additional analgesic effect for chronic pain (-13.2, [-22.5, -3.8]). The overall evidence certainty is very low; therefore, there is still uncertainty about the analgesic effects of adjunctive hypnosis. However, hypnosis adjunct to education may reduce pain intensity for chronic pain. Clarification of proposed therapeutic targets of adjunctive hypnosis to evaluate underlying mechanisms is warranted.

Abstract
Insomnia can coexist with chronic pain and is a major cause of rapidly increasing medical expenses. However, insomnia has not been fully evaluated in patients with chronic pain. This retrospective study aimed to identify the risk factors for insomnia in patients with chronic non-cancer pain. A total of 301 patients with chronic non-cancer pain were enrolled. Patients with the Athens insomnia scale scores ≥ 6 and < 6 were classified into insomnia (+) and insomnia (-) groups, respectively. All patients completed self-report questionnaires as part of their chronic pain treatment approach. Univariate and multivariate analyses were performed to predict insomnia. We found that 219 of 301 (72.8%) patients met the AIS criteria for insomnia. Significant differences were depicted between patients with and without insomnia in terms of body mass index, numeric rating scale, pain catastrophizing scale, hospital anxiety, and depression scale (HADS), pain disability assessment scale, EuroQol 5 dimension (EQ5D), and pain self-efficacy questionnaire. Multiple regression analysis identified the numeric rating scale, HADS, and EQ5D scores as factors related to insomnia in patients with chronic non-cancer pain. Anxiety, depression, and disability were associated with a greater tendency toward insomnia. HADS and EQ5D scores are useful screening tools for preventing insomnia in patients with chronic non-cancer pain.

Mobile Health App and Web Platform (eDOL) for Medical Follow-Up of Patients With Chronic Pain: Cohort Study Involving the French eDOL National Cohort After 1 Year. JMIR Mhealth Uhealth 2024; 12:e54579. [PMID: 38865173 PMCID: PMC11208841 DOI: 10.2196/54579] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Revised: 03/13/2024] [Accepted: 03/27/2024] [Indexed: 06/13/2024] Open
Abstract
BACKGROUND Chronic pain affects approximately 30% of the general population, severely degrades quality of life and professional life, and leads to additional health care costs. Moreover, the medical follow-up of patients with chronic pain remains complex and provides only fragmentary data on painful daily experiences. This situation makes the management of patients with chronic pain less than optimal and may partly explain the lack of effectiveness of current therapies. Real-life monitoring of subjective and objective markers of chronic pain using mobile health (mHealth) programs could better characterize patients, chronic pain, pain medications, and daily impact to help medical management. OBJECTIVE This cohort study aimed to assess the ability of our mHealth tool (eDOL) to collect extensive real-life medical data from chronic pain patients after 1 year of use. The data collected in this way would provide new epidemiological and pathophysiological data on chronic pain. METHODS A French national cohort of patients with chronic pain treated at 18 pain clinics has been established and followed up using mHealth tools. This cohort makes it possible to collect the determinants and repercussions of chronic pain and their evolutions in a real-life context, taking into account all environmental events likely to influence chronic pain. The patients were asked to complete several questionnaires, body schemes, and weekly meters, and were able to interact with a chatbot and use educational modules on chronic pain. Physicians could monitor their patients' progress in real time via an online platform. RESULTS The cohort study included 1427 patients and analyzed 1178 patients. The eDOL tool was able to collect various sociodemographic data; specific data for characterizing pain disorders, including body scheme; data on comorbidities related to chronic pain and its psychological and overall impact on patients' quality of life; data on drug and nondrug therapeutics and their benefit-to-risk ratio; and medical or treatment history. Among the patients completing weekly meters, 49.4% (497/1007) continued to complete them after 3 months of follow-up, and the proportion stabilized at 39.3% (108/275) after 12 months of follow-up. Overall, despite a fairly high attrition rate over the follow-up period, the eDOL tool collected extensive data. This amount of data will increase over time and provide a significant volume of health data of interest for future research involving the epidemiology, care pathways, trajectories, medical management, sociodemographic characteristics, and other aspects of patients with chronic pain. CONCLUSIONS This work demonstrates that the mHealth tool eDOL is able to generate a considerable volume of data concerning the determinants and repercussions of chronic pain and their evolutions in a real-life context. The eDOL tool can incorporate numerous parameters to ensure the detailed characterization of patients with chronic pain for future research and pain management.

Can J Anaesth 2023; 70:1765-1775. [PMID: 37919632 DOI: 10.1007/s12630-023-02596-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2022] [Revised: 04/15/2023] [Accepted: 04/20/2023] [Indexed: 11/04/2023] Open
Abstract
PURPOSE Multidisciplinary chronic pain management includes pharmacologic, psychological, and interventional strategies. In Canada, the use of interventional pain blocks (PBs) has increased in recent years. We sought to determine the distribution and clustering of PBs among physicians in Ontario, and to examine differences in the patient and physician characteristics by volume of PBs administered. METHODS We conducted a population-based cross-sectional study of PBs administered for chronic pain to Ontario residents between 1 January and 31 December 2019. Our primary outcome was the total number of PBs administered in an outpatient setting for chronic pain by eligible physicians. We used Lorenz curves, overall and stratified by PB type and physician specialty, to examine clustering of PBs among physicians, and compared patient and physician characteristics using standardized differences. RESULTS Among physicians who provided PBs, provision was highly clustered, with the top 1% of physicians providing 39% of blocks. In these high-volume PB providers, the majority of whom were general practitioners (88.4%), PBs made up the vast majority (median [interquartile range (IQR)], 87% [84-89]) of their billings, with the majority of the patients in their practices (63.0%) receiving at least one PB in 2019. Patients who received a PB from a high-volume provider had a higher annual frequency of visit for PBs (median [IQR], 10 [3-23]) and number of PBs administered per visit (median [IQR], 5 [4-6]). CONCLUSION Pain block administration is highly clustered in Ontario, with many patients receiving PBs in ways that are not supported by best evidence. Further research is required to determine whether the Ontario fee-for-service model of billing has created a suboptimal use of these health care resources.

Abstract
Multicomponent mind-body interventions are increasingly studied in oncology to improve patients' quality of life (QOL). However, the respective usefulness of each of their components or their long-term use by the participants are rarely assessed. In this study, 95 women with different cancer diagnoses participated in a self-hypnosis and self-care group. Different questionnaires were administrated before (T1), right after (T2), 3 to 4 months after (T3), and 1 year after (T4) the intervention. After the intervention, 97.5% of the participants regularly practiced any kind of relaxation (vs. 50% at baseline), especially hypnosis. The different components of the intervention (i.e., being in a group, hypnosis exercises during the sessions and at home, self-care tasks, and discussions during the group sessions) were all considered to be very useful (M = 6.91-7.75/10). One year after the intervention, the 10 most used techniques were mainly concrete activities to take care of oneself. This intervention seems very relevant for women who had cancer. Our results allow a first reflection about the mechanisms of action of our intervention.Registration: ClinicalTrials.gov (NCT03144154). Registered on the 1st of May 2017.

Abstract
Sleep disturbance can negatively affect physical and psychological health. Hypnotherapy may be effective for improving sleep with fewer side effects than other treatments. The purpose of this systematic review is to comprehensively identify studies and evidence regarding hypnotherapy for sleep disturbances. Four databases were searched to identify studies examining the use of hypnotherapy for sleep in adult populations. The search yielded 416 articles, of which 44 were included. Qualitative data analysis revealed that 47.7% of the studies showed positive results regarding the impact of hypnotherapy for sleep, 22.7% showed mixed results, and 29.5% showed no impact. A subset of 11 studies that set sleep disturbance as an inclusion criterion and included suggestions for sleep were examined separately and had more favorable results, such that 54.5% showed positive results, 36.4% showed mixed results, and 9.1% showed no impact results. Hypnotherapy appears to be a promising treatment for sleep disturbance. Future studies should report effect sizes, adverse events, and hypnotizability and include sleep-specific suggestions, standardized measures, and descriptions of hypnotherapy intervention procedures.

Abstract
Chronic pain constitutes one of the most common chronic complaints that people experience. According to the International Association for the Study of Pain, chronic pain is defined as pain that persists or recurs longer than 3 months. Chronic pain has a significant impact on individuals' well-being and psychosocial health and the economy of healthcare systems as well. Despite the availability of numerous therapeutic modalities, treatment of chronic pain can be challenging. Only about 30% of individuals with non-cancer chronic pain achieve improvement from standard pharmacological treatment. Therefore, numerous therapeutic approaches were proposed as a potential treatment for chronic pain including non-opioid pharmacological agents, nerve blocks, acupuncture, cannabidiol, stem cells, exosomes, and neurostimulation techniques. Although some neurostimulation methods such as spinal cord stimulation were successfully introduced into clinical practice as a therapy for chronic pain, the current evidence for brain stimulation efficacy in the treatment of chronic pain remains unclear. Hence, this narrative literature review aimed to give an up-to-date overview of brain stimulation methods, including deep brain stimulation, motor cortex stimulation, transcranial direct current stimulation, repetitive transcranial magnetic stimulation, cranial electrotherapy stimulation, and reduced impedance non-invasive cortical electrostimulation as a potential treatment for chronic pain.

Sleep is the most important factor reflecting the level of psychophysical well-being of a person and influencing him/her to the same extent. The greater susceptibility to sleep disturbances in patients with disabilities is associated with numerous factors. In the existing literature, there are few studies of insomnia in people with neurological disabilities. This article presents a current view on sleep disorders in disabled people and methods for their treatment.

Abstract
The assessment and management of pain and nociception is very challenging in patients unable to communicate functionally such as patients with disorders of consciousness (DoC) or in locked-in syndrome (LIS). In a clinical setting, the detection of signs of pain and nociception by the medical staff is therefore essential for the wellbeing and management of these patients. However, there is still a lot unknown and a lack of clear guidelines regarding the assessment, management and treatment of pain and nociception in these populations. The purpose of this narrative review is to examine the current knowledge regarding this issue by covering different topics such as: the neurophysiology of pain and nociception (in healthy subjects and patients), the source and impact of nociception and pain in DoC and LIS and, finally, the assessment and treatment of pain and nociception in these populations. In this review we will also give possible research directions that could help to improve the management of this specific population of severely brain damaged patients.

Abstract
BACKGROUND Virtual reality hypnosis (VRH) has emerged as a new and promising option for pain management. Nonetheless, neural dynamics of pain modulation during VRH have not been investigated yet. The aim of this study was to measure the effects of VRH on pain, combining neurophysiological and self-reported measurements. METHODS Eighteen healthy subjects underwent noxious electrical stimulations in both normal wakefulness and VRH conditions. Dissociation, absorption, time perception, anxiety, pain intensity and unpleasantness, heart rate variability and breathing were reported for each condition. EEG signals were analysed using event-related potentials (ERP) and time-frequency response (TFR) time-locked to stimuli. Neurophysiological features were correlated with self-reported data. RESULTS VRH condition was associated with lower pain and higher dissociation. VRH significantly decreased amplitudes of N100 and P200 ERP components, reduced EEG power between 1 and 5 Hz from 100 to 560 ms, and increased EEG power from 5 to 11 Hz from 340 to 800 ms. These findings were observed at frontal, central and posterior electrodes. Heart rate variability was significantly higher and breathing frequency reduced with VRH. Correlations were found between the self-reported level of pain and ERP components. CONCLUSION VRH modulates cerebral pain processes and body physiology, leading to reduced pain levels. These findings offer a first insight on the analgesic mechanisms of VRH and suggest that VRH is an effective approach to reduce experimental pain. SIGNIFICANCE VRH decreases experimental pain perception, increases subject level of dissociation and modulates cerebral pain processing mechanisms. Pain can be managed with analgesic medication but also through complementary interventions. Among these, hypnosis and virtual reality (VR) are known to reduce pain for patients and healthy individuals. In recent years, an innovative technique combining hypnosis and VR has been proposed to help patients in managing pain. However, to our knowledge, no study has focused on the underlying mechanisms of this VR/hypnosis combination. We showed that VR combined with hypnosis decreases experimental pain, increases dissociation and influences EEG modulation.

Abstract
PURPOSE OF REVIEW Cancer-related fatigue (CRF) and sleep disturbances are common symptoms among patients with cancer. They are often conceptualized as a part of a larger symptom cluster, also comprising pain and emotional distress. Despite their prevalence and long-lasting effects, CRF and sleep disturbances are still poorly addressed in clinical settings. Specific interventions are needed to manage these symptoms. RECENT FINDINGS In addition to conventional pharmacological therapies, other kinds of interventions are increasingly being developed in oncology. This review will discuss three categories of interventions for patients with cancer and their interest in alleviating CRF and sleep disturbances: physical exercises (e.g., aerobic, resistance training, running, free weights), psychological interventions (e.g., cognitive-behavioural therapy, psychoeducational interventions), and mind-body interventions (e.g., yoga, mindfulness, hypnosis). The multicomponent aspect of these interventions seems particularly important to address these symptoms. SUMMARY The findings detailed in this review will allow the scientific community, as well as health professionals working in oncology settings, to be informed about new nonpharmacological therapeutic options to help patients to manage their symptoms. It could eventually help to improve existing interventions for these patients.

Abstract
Patients with locked-in syndrome (LIS) may suffer from pain, which can significantly affect their daily life and well-being. In this study, we aim to investigate the presence and the management of pain in LIS patients. Fifty-one participants completed a survey collecting socio-demographic information and detailed reports regarding pain perception and management (type and frequency of pain, daily impact of pain, treatments). Almost half of the LIS patients reported experiencing pain (49%) that affected their quality of life, sleep and cognition. The majority of these patients reported that they did not communicate their pain to clinical staff. Out of the 25 patients reporting pain, 18 (72%) received treatment (60% pharmacological, 12% non-pharmacological) and described the treatment efficacy as 'moderate'. In addition, 14 (56%) patients were willing to try other non-pharmacological treatments, such as hypnosis or meditation. This study provides a comprehensive characterization of pain perception in LIS patients and highlights the lack of guidelines for pain detection and its management. This is especially pertinent given that pain affects diagnoses, by either inducing fatigue or by using pharmacological treatments that modulate the levels of wakefulness and concentration of such patients.

Neuroimaging Mechanism of Cognitive Behavioral Therapy in Pain Management. Pain Res Manag 2022; 2022:6266619. [PMID: 35154551 PMCID: PMC8828323 DOI: 10.1155/2022/6266619] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2021] [Accepted: 01/06/2022] [Indexed: 12/03/2022]
Abstract
Purpose. To review the recent neuroimaging studies on cognitive-behavioral therapy (CBT) for pain management, with the aim of exploring possible mechanisms of CBT. Recent Findings. Current studies can be divided into four categories, mixed pain, fibromyalgia, migraine, and experimental pain, based on the type of disease included, with the same or different changes of brain regions after CBT intervention. According to structural and functional MRI analyses, changes of brain gray matter volume, activation and deactivation of brain regions, and intrinsic connectivity between brain regions were observed after CBT sessions. The brain regions involved mainly included some areas related to cognitive and emotional regulation. After comparison, the DLPFC, OFC, VLPFC, PCC and amygdala were found to be recurrent in multiple studies and may be key regions for CBT intervention in pain management. In the treatment of mixed chronic pain, CBT may decrease the gray matter volume of DLPFC, reduce ICN connection of OFC within the DAN network, and increase fALFF of the PCC. For FM intervention, CBT may activate the bilateral OFC and VLPFC, while in migraine, only the right OFC, VLPFC, and DLPFC were found to be more activated after CBT. In addition, the differential action of the left and right amygdala has also been shown in the latest study of migraine. In heat-evoked pain, CBT may increase the deactivation of the PCC, the connectivity between the DMN and right VLPFC, while diminishing the deactivation of VLPFC. Summary. After CBT, the brain showed stronger top-down pain control, cognitive reassessment, and altered perception of stimulus signals (chronic pain and repeated acute pain). The DLPFC, OFC, VLPFC, PCC, and amygdala may be the key brain regions in CBT intervention of pain.
