Effect of Mindfulness-Based Stress Reduction vs Cognitive Behavioral Therapy or Usual Care on Back Pain and Functional Limitations in Adults With Chronic Low Back Pain: A Randomized Clinical Trial

Mindfulness for academic performance in health professions students: a systematic review

OBJECTIVES

To systematically review the impact of mindfulness-based interventions (MBIs) on the academic performance of undergraduate medicine, nursing and allied health students.

METHODS

Randomised controlled trials that examined the effects of MBIs in medicine, nursing and allied health students on academic performance were eligible for inclusion. Electronic database searches were conducted across Medline, Embase, Cochrane Central Register of Controlled Trials, Cumulative Index to Nursing and Allied Health Literature (CINAHL Plus), PsycINFO and ERIC databases. Two authors independently reviewed citations, extracted data and assessed the quality of evidence using the Cochrane Collaboration's risk of bias tool. A descriptive analysis of included studies and a meta-analysis using a random-effects model of standardised mean difference were performed.

RESULTS

A total of 267 studies were returned from the search, of which 2 met the inclusion criteria. The overall risk of bias was assessed as unclear risk of bias for one study and high risk of bias for second included study. A meta-analysis of MBIs on student academic performance as measured by marks in written examination indicated no statistical difference between interventions (Standardised Mean Difference (SMD)=0.43, 95% CI -1.77 to 2.62, I2=96%).

DISCUSSION

Our systematic review highlights a lack of evidence to either support, or refute, the use of mindfulness interventions on the academic performance of undergraduate medical students. We encourage that future randomised controlled trials pay heed to the dosing of mindfulness and include a measurement of mindfulness to enable us to draw a clearer causal relationship.

Multimodal non-invasive non-pharmacological therapies for chronic pain: mechanisms and progress

BACKGROUND

Chronic pain conditions impose significant burdens worldwide. Pharmacological treatments like opioids have limitations. Non-invasive non-pharmacological therapies (NINPT) encompass diverse interventions including physical, psychological, complementary and alternative approaches, and other innovative techniques that provide analgesic options for chronic pain without medications.

MAIN BODY

This review elucidates the mechanisms of major NINPT modalities and synthesizes evidence for their clinical potential across chronic pain populations. NINPT leverages peripheral, spinal, and supraspinal mechanisms to restore normal pain processing and limit central sensitization. However, heterogeneity in treatment protocols and individual responses warrants optimization through precision medicine approaches.

CONCLUSION

Future adoption of NINPT requires addressing limitations in standardization and accessibility as well as synergistic combination with emerging therapies. Overall, this review highlights the promise of NINPT as a valuable complementary option ready for integration into contemporary pain medicine paradigms to improve patient care and outcomes.

Mindfulness-Based Stress Reduction (MBSR) for Chronic Pain Management in the Community Pharmacy Setting: A Cross-Sectional Survey of the General Public's Knowledge and Perceptions

Patient access to mindfulness-based stress reduction (MBSR), a complementary and integrative health approach that is proven to reduce chronic pain, can be increased via community pharmacy-based implementation. However, the general public's awareness and preferences regarding MBSR as a treatment option for chronic pain, including provider roles (pharmacist vs. non-pharmacist), are unclear. Therefore, the purpose of this study was to assess the U.S. general public's knowledge, attitudes, barriers, and programmatic preferences regarding MBSR for chronic pain management, particularly in the community pharmacy setting. A cross-sectional, anonymous online survey was distributed to U.S. adults ≥18 years via the Amazon Mechanical Turk (MTurk) online survey platform. The survey instrument was informed by Anderson's framework for health service utilization. Measures were assessed using multiple-choice and 5-point Likert-type scales (1 = strongly disagree, 5 = strongly agree). Primary outcome measures included: (1) knowledge and awareness of MBSR (12-items); (2) confidence in seeking out MBSR for pain (5-items); (3) barriers to receiving MBSR (11-items); (4) beliefs about MBSR in general (12-items); (5) beliefs about community pharmacy-delivered MBSR (15-items); and (6) preferences for MBSR classes/programs (6-items). Outcomes were analyzed using descriptive statistics, and influential factors associated with mean beliefs regarding community pharmacy-delivered MBSR for chronic pain management were assessed via multiple linear regression. Of the 302 survey respondents, the majority were white (79.1%) and female (50.7%), with a mean age of 44.65 years. Respondents' self-rated MBSR knowledge (mean [SD] scale score: 2.30 [0.68]) and confidence (2.65 [0.87]) were low, although perceived barriers to access were low overall (2.22 [0.53]). Beliefs regarding the use of MBSR for treatment of chronic pain were positive in general (3.67 [0.71]), but more negative regarding community pharmacy-delivered MBSR (2.38 [0.56]). Confidence in seeking out MBSR (β = 0.297, 95% CI = 0.219 to 0.375; p < 0.001) and current opioid use (β = 0.419, 95% CI = 0.147 to 0.690; p = 0.003) were positively associated with beliefs regarding pharmacy-delivered MBSR, while annual household income (β = -0.124, 95% CI = -0.244 to -0.004; p = 0.043) and level of bodily pain (β = -0.149, 95% CI = -0.291 to -0.008; p = 0.039) exerted statistically significant negative influences. Respondents preferred a hybrid MBSR class format including both online and in-person components (29.7%) as well as both group and individual session options (43.7%). In conclusion, further education is necessary to increase the public's perception of community pharmacies as a resource for complementary and integrative health.

Pain catastrophizing is associated with reduced neural response to monetary reward

Introduction

Pain catastrophizing, a measure of an individual's negative emotional and cognitive appraisals of pain, has been included as a key treatment target in many psychological interventions for pain. However, the neural correlates of pain catastrophizing have been understudied. Prior neuroimaging evidence suggests that adults with pain show altered reward processing throughout the mesocorticolimbic reward circuitry.

Methods

In this study, we tested the association between Pain Catastrophizing Scale (PCS) scores and neural activation to the Monetary Incentive Delay (MID) reward neuroimaging task in 94 adults reporting a range of pain, insomnia, and mood symptoms.

Results

Results indicated that PCS score but not pain intensity was significantly associated with blunted activation in the caudate and putamen in response to feedback of successful vs. unsuccessful trials on the MID task. Mediation analyses indicated that PCS score fully mediated the relationship between depression symptoms and reward activation.

Discussion

These findings provide evidence that pain catastrophizing is independently associated with altered striatal function apart from depression symptoms and pain intensity. Thus, in individuals experiencing pain and/or co- morbid conditions, reward dysfunction is directly related to pain catastrophizing.

Feasibility of Mindfulness-Based Intervention for Veterans Managing Chronic Pain

Background. Chronic pain impacts people's activity participation, productivity, mental health, and sense of wellbeing. Purpose. This study aimed to (1) evaluate the feasibility of the Mindfulness-Based Chronic Pain Management (MBCPMTM) program on reducing pain perception and enhancing the quality of life, and (2) understand veterans' experience with the program. Method. The pretest-posttest single-group, mixed-methods design was used. Thirty-one veterans were offered the 12-week intervention. The Pain Catastrophizing Scale (PCS) and the Patient-Reported Outcomes Measurement Information System-29 were administered before and after the program. Focus groups and individual interviews were conducted to understand the experience. Findings. Participants' PCS scores improved (Z = -3.116, p = .002), but the pain intensity did not change significantly. Themes from qualitative data include: (1) We are not alone! (2) I have a sense of awareness, choices, and control; and (3) It does work! Implications. The study shows preliminary feasibility of MBCPMTM for veterans. This promising effect supports future rigorous testing of this intervention.

Chronic pain after spine surgery: Insights into pathogenesis, new treatment, and preventive therapy

Chronic pain after spine surgery (CPSS) is often characterized by intractable low back pain and/or radiating leg pain, and has been reported in 8-40% of patients that received lumbar spine surgery. We conducted a literature search of PubMed, MEDLINE/OVID with a focus on studies about the etiology and treatments of CPSS and low back pain. Our aim was to provide a narrative review that would help us better understand the pathogenesis and current treatment options for CPSS. This knowledge will aid in the development of optimal strategies for managing postoperative pain symptoms and potentially curing the underlying etiologies. Firstly, we reviewed recent advances in the mechanistic study of CPSS, illustrated both structural (e.g., fibrosis and scaring) and non-structural factors (e.g., inflammation, neuronal sensitization, glial activation, psychological factor) causing CPSS, and highlighted those having not been given sufficient attention as the etiology of CPSS. Secondly, we summarized clinical evidence and therapeutic perspectives of CPSS. We also presented new insights about the treatments and etiology of CPSS, in order to raise awareness of medical staff in the identification and management of this complex painful disease. Finally, we discussed potential new targets for clinical interventions of CPSS and future perspectives of mechanistic and translational research. CPSS patients often have a mixed etiology. By reviewing recent findings, the authors advocate that clinicians shall comprehensively evaluate each case to formulate a patient-specific and multi-modal pain treatment, and importantly, consider an early intraoperative intervention that may decrease the risk or even prevent the onset of CPSS.

Translational potential statement

CPSS remains difficult to treat. This review broadens our understanding of clinical therapies and underlying mechanisms of CPSS, and provides new insights which will aid in the development of novel mechanism-based therapies for not only managing the established pain symptoms but also preventing the development of CPSS.

Effects of Web-Based Mindfulness-Based Interventions on Anxiety, Depression, and Stress Among Frontline Health Care Workers During the COVID-19 Pandemic: Systematic Review and Meta-Analysis

BACKGROUND

Since 2019, the COVID-19 outbreak has spread around the world, and health care workers, as frontline workers, have faced tremendous psychological stress.

OBJECTIVE

The purpose of this study is to explore whether web-based mindfulness-based interventions continue to have a positive impact on anxiety, depression, and stress among health care workers during the COVID-19 pandemic.

METHODS

The inclusion criteria were as follows: (1) participants were frontline health care workers during the COVID-19 pandemic; (2) the experimental group was a web-based mindfulness-based intervention; (3) the control group used either general psychological intervention or no intervention; (4) outcome indicators included scales to assess anxiety, depression, and stress; and (5) the study type was a randomized controlled study. Studies that did not meet the above requirements were excluded. We searched 9 databases, including Web of Science, Embase, PubMed, Cochrane Library, Scopus, ScienceDirect, SinoMed, China National Knowledge Infrastructure (CNKI), and Wanfang Database, for randomized controlled studies on the effects of web-based mindfulness-based interventions on common mental disorder symptoms among health care workers from January 1, 2020, to October 20, 2022. The methodological quality of the included studies was assessed using the Physiotherapy Evidence Database scale. The Cochrane risk of bias tool was used to assess the risk of bias. Subgroup analysis was used to look for sources of heterogeneity and to explore whether the results were the same for subgroups under different conditions. Sensitivity analysis was used to verify the stability of the pooled results.

RESULTS

A total of 10 randomized controlled studies with 1311 participants were included. The results showed that web-based mindfulness-based interventions were effective in reducing the symptoms of anxiety (standard mean difference [SMD]=-0.63, 95% CI -0.96 to -0.31, P<.001, I2=87%), depression (SMD=-0.52, 95% CI -0.77 to -0.26, P<.001, I2=75%), and stress (SMD=-0.20, 95% CI -0.35 to -0.05, P=.01, I2=58%) among health care workers during the COVID-19 pandemic, but with wide CIs and high heterogeneity.

CONCLUSIONS

Web-based mindfulness-based interventions may be effective in reducing the symptoms of anxiety, depression, and stress among frontline health care workers during the COVID-19 pandemic. However, this effect is relatively mild and needs to be further explored by better studies in the future.

CAPER: patient preferences to inform nonsurgical treatment of chronic low back pain: a discrete-choice experiment

OBJECTIVE

We developed and used a discrete-choice measure to study patient preferences with regard to the risks and benefits of nonsurgical treatments when they are making treatment selections for chronic low back pain.

METHODS

"CAPER TREATMENT" (Leslie Wilson) was developed with standard choice-based conjoint procedures (discrete-choice methodology that mimics an individual's decision-making process). After expert input and pilot testing, our final measure had 7 attributes (chance of pain relief, duration of relief, physical activity changes, treatment method, treatment type, treatment time burden, and risks of treatment) with 3-4 levels each. Using Sawtooth software (Sawtooth Software, Inc., Provo, UT, USA), we created a random, full-profile, balanced-overlap experimental design. Respondents (n = 211) were recruited via an emailed online link and completed 14 choice-based conjoint choice pairs; 2 fixed questions; and demographic, clinical, and quality-of-life questions. Analysis was performed with random-parameters multinomial logit with 1000 Halton draws.

RESULTS

Patients cared most about the chance of pain relief, followed closely by improving physical activity, even more than duration of pain relief. There was comparatively less concern about time commitment and risks. Gender and socioeconomic status influenced preferences, especially with relation to strength of expectations for outcomes. Patients experiencing a low level of pain (Pain, Enjoyment, and General Activity Scale [PEG], question 1, numeric rating scale score<4) had a stronger desire for maximally improved physical activity, whereas those in a high level of pain (PEG, question 1, numeric rating scale score>6) preferred both maximum and more limited activity. Highly disabled patients (Oswestry Disability Index score>40) demonstrated distinctly different preferences, placing more weight on achieving pain control and less on improving physical activity.

CONCLUSIONS

Individuals with chronic low back pain were willing to trade risks and inconveniences for better pain control and physical activity. Additionally, different preference phenotypes exist, which suggests a need for clinicians to target treatments to particular patients.

The Effects of Virtual Reality Neuroscience-based Therapy on Clinical and Neuroimaging Outcomes in Patients with Chronic Back Pain: A Randomized Clinical Trial

Chronic pain remains poorly managed. The integration of innovative immersive technologies (i.e., virtual reality (VR)) with recent neuroscience-based principles that position the brain as the key organ of chronic pain may provide a more effective pain treatment than traditional behavioral therapies. By targeting cognitive and affective processes that maintain pain and potentially directly changing neurobiological circuits associated with pain chronification and amplification, VR-based pain treatment has the potential for significant and long-lasting pain relief. We tested the effectiveness of a novel VR neuroscience-based therapy (VRNT) to improve pain-related outcomes in n = 31 participants with chronic back pain, evaluated against usual care (n = 30) in a 2-arm randomized clinical trial ( NCT04468074) . We also conducted pre- and post-treatment MRI to test whether VRNT affects brain networks previously linked to chronic pain and treatment effects. Compared to the control condition, VRNT led to significantly reduced pain intensity (g = 0.63) and pain interference (g = 0.84) at post-treatment vs. pre-treatment, with effects persisting at 2-week follow-up. The improvements were partially mediated by reduced kinesiophobia and pain catastrophizing. Several secondary clinical outcomes were also improved, including disability, quality of life, sleep, and fatigue. In addition, VRNT was associated with modest increases in functional connectivity of the somatomotor and default mode networks and decreased white matter fractional anisotropy in the corpus callosum adjacent to anterior cingula, relative to the control condition. This, VRNT showed preliminary efficacy in significantly reducing pain and improving overall functioning, possibly via changes in somatosensory and prefrontal brain networks.

Research objectives and general considerations for pragmatic clinical trials of pain treatments: IMMPACT statement

ABSTRACT

Many questions regarding the clinical management of people experiencing pain and related health policy decision-making may best be answered by pragmatic controlled trials. To generate clinically relevant and widely applicable findings, such trials aim to reproduce elements of routine clinical care or are embedded within clinical workflows. In contrast with traditional efficacy trials, pragmatic trials are intended to address a broader set of external validity questions critical for stakeholders (clinicians, healthcare leaders, policymakers, insurers, and patients) in considering the adoption and use of evidence-based treatments in daily clinical care. This article summarizes methodological considerations for pragmatic trials, mainly concerning methods of fundamental importance to the internal validity of trials. The relationship between these methods and common pragmatic trials methods and goals is considered, recognizing that the resulting trial designs are highly dependent on the specific research question under investigation. The basis of this statement was an Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials (IMMPACT) systematic review of methods and a consensus meeting. The meeting was organized by the Analgesic, Anesthetic, and Addiction Clinical Trial Translations, Innovations, Opportunities, and Networks (ACTTION) public-private partnership. The consensus process was informed by expert presentations, panel and consensus discussions, and a preparatory systematic review. In the context of pragmatic trials of pain treatments, we present fundamental considerations for the planning phase of pragmatic trials, including the specification of trial objectives, the selection of adequate designs, and methods to enhance internal validity while maintaining the ability to answer pragmatic research questions.

Mindfulness meditation use in chronic pain treatment in rural Australia: Pitfalls and potential - A case report

Mindfulness is a state of awareness characterized by open and non-judgmental recognition of thoughts and sensations and an ability to resist the usual wandering of an individual's attention. Usually achieved by meditation, mindfulness is recognized as a treatment for chronic pain. Evidence, thus far, has been characterized by poor quality trials and mixed results, but a growing body of research is further investigating its effectiveness. Despite inconclusive evidence, the inherent difficulties of mindfulness research, and problems of accessibility in rural settings, mindfulness meditation is an emerging treatment strategy for many chronic pain patients. This report presents the case of a patient admitted to a rural hospital in New South Wales, whose quality of life was severely impacted by chronic pain.

Effect of mindfulness-based mind-body therapies in patients with non-specific low back pain-A network meta-analysis of randomized controlled trials

Background/objectives

Although mindfulness-based mind-body therapy (MBMBT) is an effective non-surgical treatment for patients with non-specific low back pain (NLBP), the best MBMBT mode of treatment for NLBP patients has not been identified. Therefore, a network meta-analysis (NMA) was conducted to compare the effects of different MBMBTs in the treatment of NLBP patients.

Methods

PubMed, EMBASE, Cochrane Central Register of Controlled Trials, and Web of Science databases were searched for randomized controlled trials (RCTs) applying MBMBT for the treatment of NLBP patients, with all of the searches ranging from the time of database creation to January 2023. After 2 researchers independently screened the literature, extracted information, and evaluated the risks of biases in the included studies, the data were analyzed by using Stata 16.0 software.

Results

A total of 46 RCTs were included, including 3,886 NLBP patients and 9 MBMBT (Yoga, Ayurvedic Massage, Pilates, Craniosacral Therapy, Meditation, Meditation + Yoga, Qigong, Tai Chi, and Dance). The results of the NMA showed that Craniosacral Therapy [surface under the cumulative ranking (SUCRA): 99.2 and 99.5%] ranked the highest in terms of improving pain and disability, followed by Other Manipulations (SUCRA: 80.6 and 90.8%) and Pilates (SUCRA: 54.5 and 71.2%). In terms of improving physical health, Craniosacral Therapy (SUCRA: 100%) ranked the highest, followed by Pilates (SUCRA: 72.3%) and Meditation (SUCRA: 55.9%). In terms of improving mental health, Craniosacral Therapy (SUCRA: 100%) ranked the highest, followed by Meditation (SUCRA: 70.7%) and Pilates (SUCRA: 63.2%). However, in terms of improving pain, physical health, and mental health, Usual Care (SUCRA: 7.0, 14.2, and 11.8%, respectively) ranked lowest. Moreover, in terms of improving disability, Dance (SUCRA: 11.3%) ranked lowest.

Conclusion

This NMA shows that Craniosacral Therapy may be the most effective MBMBT in treating NLBP patients and deserves to be promoted for clinical use.

Chronic pain, chronic stress and substance use: overlapping mechanisms and implications

Chronic pain is among the most common reasons adults in the U.S. seek medical care. Despite chronic pain's substantial impact on individuals' physical, emotional, and financial wellness, the biologic underpinnings of chronic pain remain incompletely understood. Such deleterious impact on an individuals' wellness is also manifested in the substantial co-occurrence of chronic stress with chronic pain. However, whether chronic stress and adversity and related alcohol and substance misuse increases risk of developing chronic pain, and, if so, what the overlapping psychobiological processes are, is not well understood. Individuals suffering with chronic pain find alleviation through prescription opioids as well as non-prescribed cannabis, alcohol, and other drugs to control pain, and use of these substances have grown significantly. Substance misuse also increases experience of chronic stress. Thus, given the evidence showing a strong correlation between chronic stress and chronic pain, we aim to review and identify overlapping factors and processes. We first explore the predisposing factors and psychologic features common to both conditions. This is followed by examining the overlapping neural circuitry of pain and stress in order to trace a common pathophysiologic processes for the development of chronic pain and its link to substance use. Based on the previous literature and our own findings, we propose a critical role for ventromedial prefrontal cortex dysfunction, an overlapping brain area associated with the regulation of both pain and stress that is also affected by substance use, as key in the risk of developing chronic pain. Finally, we identify the need for future research in exploring the role of medial prefrontal circuits in chronic pain pathology. Critically, in order to alleviate the enormous burden of chronic pain without exacerbating the co-occurring substance misuse crisis, we emphasize the need to find better approaches to treat and prevent chronic pain.

Combining Procedural and Behavioral Treatments for Chronic Low Back Pain: A Pilot Feasibility Randomized Controlled Trial

Individual treatments for chronic low back pain (CLBP) have small magnitude effects. Combining different types of treatments may produce larger effects. This study used a 2×2 factorial randomized controlled trial (RCT) design to combine procedural and behavioral treatments for CLBP. The study aims were to: (1) assess feasibility of conducting a factorial RCT of these treatments; and (2) estimate individual and combined treatment effects of (a) lumbar radiofrequency ablation (LRFA) of the dorsal ramus medial branch nerves (vs. a simulated LRFA control procedure) and (b) Activity Tracker-Informed Video-Enabled Cognitive Behavioral Therapy program for CLBP (AcTIVE-CBT) (vs. an educational control treatment) on back-related disability at 3 months post-randomization. Participants (n=13) were randomized in a 1:1:1:1 ratio. Feasibility goals included an enrollment proportion ≥30%, a randomization proportion ≥80%, and a ≥80% proportion of randomized participants completing the 3-month Roland-Morris Disability Questionnaire (RMDQ) primary outcome endpoint. An intent-to-treat analysis was used. The enrollment proportion was 62%, the randomization proportion was 81%, and all randomized participants completed the primary outcome. Though not statistically significant, there was a beneficial, moderate-magnitude effect of LRFA vs. control on 3-month RMDQ (-3.25 RMDQ points; 95% CI: -10.18, 3.67). There was a significant, beneficial, large-magnitude effect of AcTIVECBT vs. control (-6.29, 95% CI: -10.97, -1.60). Though not statistically significant, there was a beneficial, large effect of LRFA+AcTIVE-CBT vs. control (-8.37; 95% CI: -21.47, 4.74). We conclude that it is feasible to conduct an RCT combining procedural and behavioral treatments for CLBP.

Subjective effects and perceived mechanisms of change of cognitive behavioral and mindfulness-based online interventions for low sexual desire in women

Cognitive-behavioral (CBT) and mindfulness-based therapy (MBT) are effective treatments for Hypoactive Sexual Desire Dysfunction (HSDD) in women. To date, evidence regarding the mechanisms of these treatments for improving low sexual desire is still lacking. To gain comprehensive information on the subjective effects and perceived mechanisms of change of CBT and MBT for HSDD, semi-structured qualitative interviews were conducted with 51 cis-women who participated in a trial investigating internet-based CBT and MBT for HSDD. Data were analyzed with deductive and inductive content analysis. Subjective treatment effects included increased desire, improved communication, and greater self-acceptance. Different mechanisms of change for CBT and MBT were endorsed by participants. This study provides tangible evidence of the different pathways through which CBT and MBT can improve women's sexual desire.

Mindfulness-Based Interventions for the Reduction of Postoperative Pain in Hip and Knee Arthroplasty Patients: A Systematic Review and Meta-Analysis

PURPOSE

The aim of this systematic review and meta-analysis is to evaluate the effect of mindfulness-based interventions (MBIs) on post-surgical pain in patients undergoing a total hip replacement (THR) or total knee replacement (TKR).

METHODS

We performed a systematic review and meta-analysis in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. A search of multiple databases, including PubMed and EMBASE, was performed for studies from database inception through March 2nd, 2022. Data were extracted, and pooled estimates of standardized mean differences in pain scores were calculated using a random effects model and inverse probability weighting.

RESULTS

Two randomized control trials were eligible for inclusion (299 patients). The average ages of participants in each study were similar at 65.5 and 64.8 years, and both studies were predominantly female at 72.4% and 61.9%. The mindfulness intervention ranged from an eight-week program to a 20-minute session. Both individual studies reported statistically significant reductions in postoperative pain for MBI groups. The pooled standardized mean difference in pain scores for the MBI groups compared to the control groups was -1.94 (-3.39; -0.48).

CONCLUSIONS

There exists preliminary evidence for the beneficial effect of MBIs on reducing the postoperative pain experience in this patient population. Given the significant consequences of postoperative pain and the necessity for non-opioid forms of analgesia, this topic represents a promising area of research that warrants future randomized control trials to better understand the role of MBIs for postoperative analgesia.

Effects of an online program including mindfulness, exercise therapy and patient education compared to online exercise therapy and patient education for people with Patellofemoral Pain: protocol for a randomized clinical trial

BACKGROUND

Patellofemoral pain (PFP) is a common knee disorder that causes persistent pain, lower self-reported function and quality of life. People with PFP also present with altered psychological factors, which are associated with higher levels of pain and dysfunction. Mindfulness-based interventions (MBI) generally consist of meditative practices developed to provide a holistic approach to chronic conditions. However, the effects of MBI on clinical and psychological outcomes for people with PFP remains understudied.

METHODS

This assessor-blinded, parallel, two-arm randomized clinical trial aims to investigate the effects of adding an 8-week online MBI program to exercise therapy and patient education on clinical and psychological factors for people with PFP. We also aim to investigate whether psychological factors mediate changes in pain and function. Sixty-two participants with PFP will be recruited and randomized into one of two treatment groups (Mindfulness or Control group). Both groups will receive an 8-week intervention involving exercise therapy and education delivered through an online platform. The Mindfulness group will additionally receive a MBI component including formal and informal practices. Outcomes will be assessed online at baseline, intervention endpoint (follow-up 1) and 12 months after intervention completion (follow-up 2). Comparisons between groups will be performed at all time points with linear mixed models. A mediation analysis will be performed using a 3-variable framework.

DISCUSSION

Exercise therapy and patient education are considered the "best management" options for PFP. However, unsatisfactory long-term prognosis remains an issue. It is known that people with PFP present with altered psychological factors, which should be considered during the evaluation and treatment of people with PFP. Adding a MBI to the current best treatment for PFP may improve short and long-term effects by addressing the underlying psychological factors.

Effects of a online brief modified mindfulness-based stress reduction therapy for anxiety among Chinese adults: A randomized clinical trial

The COVID-19 pandemic has exacerbated anxiety and related symptoms among the general population. In order to cope with the mental health burden, we developed an online brief modified mindfulness-based stress reduction (mMBSR) therapy. We performed a parallel-group randomized controlled trial to evaluate the efficacy of the mMBSR for adult anxiety with cognitive-behavioral therapy (CBT) as an active control. Participants were randomized to mMBSR, CBT or waitlist group. Those in the intervention arms performed each therapy for 6 sections in 3 weeks. Measurements were conducted at baseline, post-treatment and 6 months post-treatment by Generalized Anxiety Disorder-7, Patient Health Questionnaire-9, Patient Health Questionnaire-15, reverse scored Cohen Perceived Stress scale, Insomnia Severity Index, and Snaith-Hamilton Pleasure Scale. 150 participants with anxiety symptoms were randomized to mMBSR, CBT or waitlist group. Post intervention assessments showed that mMBSR improved the scores of all the six mental problem dimensions (anxiety, depression, somatization, stress, insomnia, and the experience of pleasure) significantly compared to the waitlist group. During 6-month post treatment assessment, the scores of all six mental problem dimensions in the mMBSR group still showed improvement compared to baseline and showed no significant difference with the CBT group. Our results provide positive evidence for the efficacy and feasibility of an online brief modified MBSR program to alleviate anxiety and related symptoms of individuals from the general population, and the therapeutic benefits of mMBSR persisted for up to six months. This low resource-consuming intervention could facilitate the challenges of supplying psychological health therapy to large scale of population.

Randomized controlled trial protocol of health coaching for veterans with complex chronic pain

BACKGROUND

Pain predominant multisymptom illness (pain-CMI) refers to symptom-based conditions where pain is a primary symptom. There is initial evidence that health coaching may be efficacious in treating pain-CMI because it can be tailored to the veteran's goals and emphasizes long-term behavior change, which may indirectly impact the maintaining factors of pain-CMI (e.g., catastrophizing, poor pain control, and limited activity). This paper describes the study protocol and rationale of a randomized controlled trial that will compare the efficacy of remote-delivered health coaching in reducing disability and pain impairment for veterans with pain-CMI to remote-delivered supportive psychotherapy.

METHODS

This randomized controlled trial will consist of two treatment arms: remote-delivered health coaching and remote-delivered supportive psychotherapy, the active control. Each treatment condition will consist of twelve, weekly one-on-one meetings with a study provider. In addition to the baseline assessment, participants will also complete 6-week (mid-treatment), 12-week (post-treatment), and 24-week (follow-up) assessments that consist of questionnaires that can be completed remotely. The primary aims for this study are to determine whether health coaching reduces disability and pain impairment as compared to supportive psychotherapy. We will also examine whether health coaching reduces physical symptoms, catastrophizing, limiting activity, and increasing pain control as compared to supportive psychotherapy.

DISCUSSION

This study will contribute to the existing literature on pain-CMI and report the effectiveness of a novel, remote-delivered behavioral intervention.

Optimising psychological treatment for pain after breast cancer: a factorial design study protocol in Denmark

INTRODUCTION

One in five breast cancer (BC) survivors are affected by persistent pain years after completing primary treatment. While the efficacy of psychological interventions for BC-related pain has been documented in several meta-analyses, reported effect sizes are generally modest, pointing to a need for optimisation. Guided by the Multiphase Optimization Strategy, the present study aims to optimise psychological treatment for BC-related pain by identifying active treatment components in a full factorial design.

METHODS AND ANALYSIS

The study uses a 2×3 factorial design, randomising 192 women with BC-related pain (18-75 years) to eight experimental conditions. The eight conditions consist of three contemporary cognitive-behavioural therapy components, namely: (1) mindful attention, (2) decentring, and (3) values and committed action. Each component is delivered in two sessions, and each participant will receive either zero, two, four or six sessions. Participants receiving two or three treatment components will be randomised to receive them in varying order. Assessments will be conducted at baseline (T1), session by session, every day for 6 days following the first session in each treatment component, at post-intervention (T2) and at 12-week follow-up (T3). Primary outcomes are pain intensity (Numerical Rating Scale) and pain interference (Brief Pain Inventory interference subscale) from T1 to T2. Secondary outcomes are pain burden, pain quality, pain frequency, pain catastrophising, psychological distress, well-being and fear of cancer recurrence. Possible mediators include mindful attention, decentring, and pain acceptance and activity engagement. Possible moderators are treatment expectancy, treatment adherence, satisfaction with treatment and therapeutic alliance.

Comparing the clinical and cost-effectiveness of remote (telehealth and online) cognitive behavioral therapy-based treatments for high-impact chronic pain relative to usual care: study protocol for the RESOLVE multisite randomized control trial

BACKGROUND

Cognitive behavioral therapy for chronic pain (CBT-CP) is an effective but underused treatment for high-impact chronic pain. Increased access to CBT-CP services for pain is of critical public health importance, particularly for rural and medically underserved populations who have limited access due to these services being concentrated in urban and high income areas. Making CBT-CP widely available and more affordable could reduce barriers to CBT-CP use.

METHODS

As part of the National Institutes of Health Helping to End Addiction Long-term® (NIH HEAL) initiative, we designed and implemented a comparative effectiveness, 3-arm randomized control trial comparing remotely delivered telephonic/video and online CBT-CP-based services to usual care for patients with high-impact chronic pain. The RESOLVE trial is being conducted in 4 large integrated healthcare systems located in Minnesota, Georgia, Oregon, and Washington state and includes demographically diverse populations residing in urban and rural areas. The trial compares (1) an 8-session, one-on-one, professionally delivered telephonic/video CBT-CP program; and (2) a previously developed and tested 8-session online CBT-CP-based program (painTRAINER) to (3) usual care augmented by a written guide for chronic pain management. Participants are followed for 1 year post-allocation and are assessed at baseline, and 3, 6, and 12 months post-allocation. The primary outcome is minimal clinically important difference (MCID; ≥ 30% reduction) in pain severity (composite of pain intensity and pain-related interference) assessed by a modified 11-item version of the Brief Pain Inventory-Short Form at 3 months. Secondary outcomes include pain severity, pain intensity, and pain-related interference scores, quality of life measures, and patient global impression of change at 3, 6, and 12 months. Cost-effectiveness is assessed by incremental cost per additional patient with MCID in primary outcome and by cost per quality-adjusted life year achieved. Outcome assessment is blinded to group assignment.

DISCUSSION

This large-scale trial provides a unique opportunity to rigorously evaluate and compare the clinical and cost-effectiveness of 2 relatively low-cost and scalable modalities for providing CBT-CP-based treatments to persons with high-impact chronic pain, including those residing in rural and other medically underserved areas with limited access to these services.

Pain education and pain management skills in virtual reality in the treatment of chronic low back pain: A multiple baseline single-case experimental design

Chronic lower back pain is a major health problem and current treatments do not always lead to adequate pain control. Virtual reality (VR) is an upcoming technology that has shown to be effective in reducing acute pain. However, the value of VR in reducing chronic pain is still unknown. Therefore, the current study focuses on the effects of a recently developed VR application 'Reducept' using a multiple baseline single-case experimental design in 8 patients (N = 8). Reducept is a VR-training program aiming to improve pain management skills and providing pain education in patients with (chronic lower) back pain. Results based on visual and statistical analyses indicated that Reducept has the potential to reduce chronic lower back pain, although its clinical relevance was small. This study is one of the first that focuses on the possible effects of Reducept using sophisticated visual and statistical analyses. Our study shows a detailed overview of individual changes in pain intensity over time. Further research is necessary to investigate the working mechanism of Reducept and its impact on chronic pain conditions.

Effects of meditation on pain intensity, physical function, quality of life and depression in adults with low back pain - A systematic review with meta-analysis

BACKGROUND

Low back pain (LBP) is a common biopsychosocial health problem. Meditation may provide a complementary treatment option for LBP patients.

OBJECTIVES

The aim of this systematic review with meta-analysis was to examine the effects of meditation on pain intensity, functional disability, quality of life, and depression in LBP populations.

METHODS

This systematic review was conducted according to the PRISMA Guidelines. PubMed, Web of Science, CENTRAL, CamQuest and PubPsych were searched up to a publication date of June 2020. Inclusion criteria were RCTs or non-RCTs with LBP patients, aged at least 18 years, the application of a specific meditation technique, and pain intensity and/or functional disability as outcomes. Pooled SMDs were calculated at post-treatment and follow up. The Cochrane risk-of-bias tool was used to estimate risk of bias. The overall quality of evidence was assessed using the GRADE approach.

RESULTS

12 studies with a total of 1005 participants were included in this review. Compared to controls, meditation solely showed a significant positive effect on pain intensity (SMD = -0.27 [CI -0.43; -0.11]; p = 0.001; based on 10 studies with 934 participants) and physical quality of life (SMD = 0.21 [CI 0.07; 0.36]; p = 0.005; based on 5 studies with 756 participants) at post-treatment. At follow up (mean 20 weeks, range 4-52) there were no significant effects anymore. The quality of the evidence was moderate due to study limitations and imprecision.

CONCLUSIONS

Meditation seems to be promising with regard to reducing short-term pain intensity in patients with LBP. However, additional well-designed and large trials are required in order to draw more reliable conclusions.

Low back pain patients' perceived effectiveness of utilizing complementary and alternative medicine: a systematic review of qualitative studies

OBJECTIVES

The purpose of this systematic review of qualitative studies is to explore patients' perceived effectiveness of utilizing complementary and alternative medicine (CAM) for the treatment and/or management of low back pain (LBP).

METHODS

MEDLINE, EMBASE, AMED, and CINAHL were systematically searched from database inception until May 2020. Eligible articles included qualitative data about LBP patients' perceptions of using CAM.

RESULTS

Of 1,567 items, 1,542 items were excluded; the remaining 25 articles were included in this review. Three themes emerged as follows: physical benefits; mental health benefits; and negative or no perceived effectiveness of CAM on patients with LBP.

CONCLUSIONS

This study explores perceptions of CAM effectiveness among patients with LBP. These findings provide valuable information to CAM and non-CAM practitioners regarding the importance of individualized patient care based on their preferences, values, needs, and perspectives. Further exploration could include practitioners' perceptions of CAM and their impact on the patient-practitioner relationship.

Mindfulness and Chronic Musculoskeletal Pain: An Umbrella Review

Background

Chronic musculoskeletal pain (CMSP) disorders are a leading cause of disability globally, affecting up to one in three people. Mindfulness-based interventions (MBI) have become a popular treatment for CMSP. The aim of this umbrella review was to synthesise the best available research evidence for the effectiveness of MBI for adults with CMSP.

Methods

Eight databases were searched from inception to 30th June 2021 for systematic reviews that examined the use of MBI in CMSP (pain experienced >3 months) in adult populations. Two reviewers independently conducted screening and selection, data extraction, and assessment of methodological quality using The Assessing the Methodological Quality of Systematic Reviews tool (AMSTAR 2). Outcomes examined were pain, sleep quality, depression, quality of life, physical functioning, and mindfulness. Furthermore, definitions of mindfulness, and intervention parameters (mindfulness practices used, length, frequency of sessions, duration) were also reported.

Results

Nineteen systematic reviews (n = 1 rated high quality, n = 1 moderate quality, n = 2 low quality and n = 15 critically low quality) examining 194 primary studies met the review criteria. Although some promising evidence was identified for the use of MBI in CMSP, the general low quality and widespread heterogeneity of included SRs and made it difficult to reach a definitive conclusion. Differences in results and outcomes amongst systematic reviews that, in many cases, had a high overlap of included RCTs, suggests fundamental differences in critical design elements that make data difficult to compare.

Conclusion

This umbrella review found mixed results on the effectiveness of MBI for the management of CMSP across a range of outcomes (pain, sleep quality, depression, quality of life, physical functioning, mindfulness). Definitions of MBI varied as did parameters, which may have contributed to these mixed results. More rigorous research with stringent MBI protocols is required.

Disentangling self from pain: mindfulness meditation-induced pain relief is driven by thalamic-default mode network decoupling

ABSTRACT

For millenniums, mindfulness was believed to diminish pain by reducing the influence of self-appraisals of noxious sensations. Today, mindfulness meditation is a highly popular and effective pain therapy that is believed to engage multiple, nonplacebo-related mechanisms to attenuate pain. Recent evidence suggests that mindfulness meditation-induced pain relief is associated with the engagement of unique cortico-thalamo-cortical nociceptive filtering mechanisms. However, the functional neural connections supporting mindfulness meditation-based analgesia remain unknown. This mechanistically focused clinical trial combined functional magnetic resonance imaging with psychophysical pain testing (49°C stimulation and pain visual analogue scales) to identify the neural connectivity supporting the direct modulation of pain-related behavioral and neural responses by mindfulness meditation. We hypothesized that mindfulness meditation-based pain relief would be reflected by greater decoupling between brain mechanisms supporting appraisal (prefrontal) and nociceptive processing (thalamus). After baseline pain testing, 40 participants were randomized to a well-validated, 4-session mindfulness meditation or book-listening regimen. Functional magnetic resonance imaging and noxious heat (49°C; right calf) were combined during meditation to test study hypotheses. Mindfulness meditation significantly reduced behavioral and neural pain responses when compared to the controls. Preregistered (NCT03414138) whole-brain analyses revealed that mindfulness meditation-induced analgesia was moderated by greater thalamus-precuneus decoupling and ventromedial prefrontal deactivation, respectively, signifying a pain modulatory role across functionally distinct neural mechanisms supporting self-referential processing. Two separate preregistered seed-to-seed analyses found that mindfulness meditation-based pain relief was also associated with weaker contralateral thalamic connectivity with the prefrontal and primary somatosensory cortex, respectively. Thus, we propose that mindfulness meditation is associated with a novel self-referential nociceptive gating mechanism to reduce pain.

Moderators and Nonspecific Predictors of Treatment Benefits in a Randomized Trial of Mindfulness-Based Stress Reduction vs Cognitive-Behavioral Therapy vs Usual Care for Chronic Low Back Pain

Both mindfulness-based stress reduction (MBSR) and cognitive-behavioral therapy (CBT) are effective for chronic low back pain (CLBP), but little is known regarding who might benefit more from one than the other. Using data from a randomized trial comparing MBSR, CBT, and usual care (UC) for adults aged 20 to 70 years with CLBP (N = 297), we examined baseline characteristics that moderated treatment effects or were associated with improvement regardless of treatment. Outcomes included 8-week function (modified Roland Disability Questionnaire), pain bothersomeness (0-10 numerical rating scale), and depression (Patient Health Questionnaire-8). There were differences in the effects of CBT versus MBSR on pain based on participant gender (P = .03) and baseline depressive symptoms (P = .01), but the only statistically significant moderator after Bonferroni correction was the nonjudging dimension of mindfulness. Scores on this measure moderated the effects of CBT versus MBSR on both function (P = .001) and pain (P = .04). Pain control beliefs (P <.001) and lower anxiety (P < .001) predicted improvement regardless of treatment. Replication of these findings is needed to guide treatment decision-making for CLBP. TRIAL REGISTRATION: The trial and analysis plan were preregistered in ClinicalTrials.gov (Identifier: NCT01467843). PERSPECTIVE: Although few potential moderators and nonspecific predictors of benefits from CBT or MBSR for CLBP were statistically significant after adjustment for multiple comparisons, these findings suggest potentially fruitful directions for confirmatory research while providing reassurance that patients could reasonably expect to benefit from either treatment.

Feasibility and Acceptability of Online Recruitment and an Online Brief Mindfulness Intervention Among Patients With Sickle Cell Disease

Background Pain among young adult patients with sickle cell disease (PWSCD) is a highly significant public health problem associated with reduced quality of life. Due to issues uniquely affecting PWSCD, including distrust of research, challenging life situations, debilitating pain, stigma, and logistical challenges (e.g., child or elder care and transportation), SCD researchers often find it challenging to meet sample size and enrollment targets. To our knowledge, all known SCD studies have solely recruited participants in person (e.g., clinics and local organizations) and utilized lengthy interventions with suboptimal recruitment and retention results. Newer recruitment methods, such as online recruitment, need to be explored for research among PWSCD. In this pilot project, we sought to address these challenges by investigating: 1) a novel method of using online outreach to recruit/enroll young PWSCD and 2) a novel, brief online mindfulness intervention adapted from Mindfulness-Oriented Recovery Enhancement (MORE): Mini-MORE designed to treat pain among PWSCD.  Methods Participants (N = 32) were recruited online (e.g., paid advertisements on Facebook and NextDoor; free advertisements on Facebook groups and Reddit) and screened by phone from October 25 to November 8, 2022. Participants watched an online Mini-MORE video. Immediately before and after watching the video, participants rated their pain intensity and unpleasantness on an 11-point numeric rating scale (NRS). Afterward, participants were emailed an individualized link to additional audio recordings for ongoing practice. Immediately before and after accessing the additional recordings, participants rated their pain intensity, anxiety, and depression on an 11-point NRS. T-tests were used to examine the impact of Mini MORE on outcomes at two-time points. Results A total of 84 participants completed the self-screening. The majority of self-screeners resulted from free posts in Facebook groups (77%), Reddit (1%), and Craigslist (6%). Thirty-two (32) eligible participants agreed to join a Zoom meeting to watch the video. The entire Mini-MORE video was viewed by 31 of 32 participants (97%). Pain intensity decreased by 1.7 points (p<0.001, Cohen's d=2.19), and pain unpleasantness decreased by 2.1 points (p<0.001, Cohen's d=2.20). Listening to the supplemental recordings was associated with significant, immediate decreases in pain intensity by 1.3 points (p=0.015, Cohen's d=2.05), anxiety by 1.8 points (p=0.022, Cohen's d=3.10), and depression by 1.74 points (p=0.019, Cohen's d=2.94). Conclusions Results suggest that online methods are feasible in recruiting and enrolling young PWSCD, and the online Mini-MORE intervention is acceptable among PWSCD. Future research is needed to assess whether Mini-MORE is associated with decreased pain symptomology in young PWSCD.

Rate and Predictors of Patients with Chronic Pain Establishing Care with Pain Psychology Following Pain Physician Referral

OBJECTIVE

To determine, among patients with chronic pain who had received pain physician referral to pain psychology, the rate of establishing care and factors related to establishing care with pain psychology.

DESIGN

Retrospective study.

SETTING

Academic tertiary care center.

SUBJECTS

Patients from the University of California, San Diego (UCSD) Center for Pain Medicine.

METHODS

This was an institutional review board-approved, retrospective study of 150 consecutive referrals of unique patients from UCSD Pain Medicine to UCSD Pain Psychology.

RESULTS

Of 150 patients referred to pain psychology, 74 (49.3%) established care with pain psychology. Of 98 patients who had previously seen mental health services, 58 established care with pain psychology (59.2%; 95% confidence interval [CI]: 49% to 69%), whereas of 52 patients who had not previously seen mental health services, 16 established care with pain psychology (30.8%; 95% CI: 18% to 43%) (odds ratio [OR] 3.26; 95% CI: 1.60 to 6.66). In the patient subset with depression and/or anxiety, of 82 patients who had previously seen mental health services, 47 established care with pain psychology (57.3%; 95% CI: 47% to 68%), whereas of 20 patients who had not previously seen mental health services, three established care with pain psychology (15%; 95% CI: -1% to 31%) (OR 7.61; 95% CI: 2.07 to 28.01). Of 96 patients referred for general pain psychology evaluations, 43 established care (45%; 95% CI: 35% to 55%), whereas of 38 patients referred for preprocedural evaluation for an implantable device, 24 established care (63%; 95% CI: 48% to 78%).

CONCLUSION

Patients are significantly more likely to establish care with pain psychology if they have previously seen a mental health professional. This was even more marked among the patient subset with a history of depression and/or anxiety who had engaged in mental health services than among those with a history of depression and/or anxiety who had not engaged in mental health services. Whether referral was for general psychological evaluation or preprocedural evaluation for an implantable device did not significantly influence whether patients established care. Targeted interventions are needed to improve the likelihood of patients engaging with pain psychology services.

Understanding the confluence of injury and obesity in a Grade 2 obesity and above population

OBJECTIVE

Obesity and injury are major inter-related public health challenges. The objective of this study was to explore the perceptions of injury in people with severe obesity.

METHODS

A cross-sectional design was employed to capture injury perception and lifestyle habits via questionnaires. Weight (kg) and height (m) were measured by clinicians for patients attending a weight loss group program. Univariate, chi-square, ANOVA and ordinal regression analyses were undertaken.

RESULTS

There were 292 participants (67.1% female), mean age 49.3 years and Body Mass Index 47.2 kg/m² (range 30.7-91.9 kg/m²). Concern about having an injury was found in 83%, and 74.2% thought that weight would increase the likelihood of injury. A greater concern of being injured at baseline was associated with less weight loss at eight weeks (F=3.567; p=0.03). Depression, anxiety and sleepiness score were higher in those who reported greater 'Concern about having an injury'.

CONCLUSIONS

People with obesity fear injury and falling, which limits their willingness to exercise. Anxiety symptoms appear to exacerbate this connection.

IMPLICATIONS FOR PUBLIC HEALTH

In individuals with obesity, anxiety, sleepiness and depression are associated with a fear of being injured. Addressing fear and reducing anxiety may decrease barriers to participating in physical activity.

The Effects of Clinical Meditation Programs on Stress and Well-Being

Abstract. Many people suffer from chronic conditions, such as cancer, diabetes, or depression. The use and development of meditation interventions to offer complementary psychological treatment for such patients is increasing, as is criticism of research on this topic. Therefore, the aim of the present rapid review and meta-analysis is to investigate the effects of meditation interventions in randomized controlled trials of clinical populations on perceived stress and well-being. A search was conducted in MEDLINE, Web of Science, PsycInfo, CINAHL, PsycArticles, and PSYNDEX between July 2013 and April 13, 2021. Three-level random effect models were estimated. Based on 316 effect sizes, small effects of meditation interventions were found (stress: g = 0.18; well-being: g = 0.25) largely paralleling findings of a previous meta-analysis. An important limitation is the potentially high risk of bias for individual studies. Overall, meditation interventions appear to be beneficial for complementary treatment of chronic clinical conditions.

Association between history of childbirth and chronic, functionally significant back pain in later life

BACKGROUND

Back pain is more prevalent among women than men. The association with sex could be related to pregnancy and childbirth, unique female conditions. This association has not been thoroughly evaluated.

METHODS

Using a retrospective cohort design, we evaluated the relationship between history of childbirth on the prevalence and severity of functionally consequential back pain in 1069 women from a tertiary care pain management clinic. Interactions among preexisting, acute peripartum, and subsequent back pain were evaluated as secondary outcomes among the parous women using logistic and linear regression as appropriate.

RESULTS

The women who had given birth had a higher risk for functionally significant back pain compared to women who had not given birth (85% vs 77%, p < 0.001, Risk Ratio 1.11 [1.04-1.17]). The association was preserved after correction for age, weight, and race. Back pain was also more slightly severe (Numerical Rating Score for Pain 7[5-8] vs 6[5-7] out of 10, p = 0.002). Women who recalled severe, acute postpartum back pain had a higher prevalence of current debilitating back pain (89% vs 75%, Risk Ratio 1.19 (1.08-1.31), p = 0.001). Twenty-eight percent of acute postpartum back pain never resolved and 40% reported incomplete resolution.

CONCLUSIONS

A history of pregnancy and childbirth is a risk factor for chronic functionally significant back pain in women. Severe acute postpartum back pain is a risk factor for future disability suggesting that the peripartum period may provide an important opportunity for intervention. Early recognition and management may mitigate future disability.

TRIAL REGISTRATION

The study was registered with clinicaltrials.gov as "Association Between Chronic Headache and Back Pain with Childbirth" (NCT04091321) on 16/09/2019 before it was initiated.

The Reliability of Rating via Audio-Recording Using the Mindfulness-Based Interventions: Teaching Assessment Criteria

Background

The Mindfulness-Based Interventions: Teaching Assessment Criteria (MBI:TAC) is an important tool for assessing teacher skill and aspects of the fidelity of mindfulness-based interventions, but prior research on and implementation of the MBI:TAC has used video recordings, which can be difficult to obtain, share for assessments, and which increase privacy concerns for participants. Audio-only recordings might be a useful alternative, but their reliability is unknown.

Objective

To assess evaluator perception of the rating process and inter-rater reliability of MBI:TAC ratings using audio-only recordings.

Methods

We prepared audio-only files from video recordings of 21 previously rated Mindfulness-Based Stress Reduction teachers. Each audio recording was rated by 3 trained MBI:TAC assessors drawn from a pool of 12 who had previously participated in rating the video recordings. Teachers were rated by evaluators who had not viewed the video recording and did not know the teacher. We then conducted semi-structured interviews with evaluators.

Results

On the 6 MBI:TAC domains, the intraclass correlation coefficients (ICCs) for audio recordings ranged from .53 to .69 using an average across 3 evaluators. Using a single rating resulted in lower ICCs (.27-.38). Bland-Altman plots showed audio ratings had little consistent bias compared to video recordings and agreed more closely for teachers with higher ratings. Qualitative analysis identified 3 themes: video recordings were particularly helpful when rating less skillful teachers, video recordings tended to provide a more complete picture for rating, and audio rating had some positive features.

Conclusions

Inter-rater reliability of the MBI:TAC using audio-only recordings was adequate for many research and clinical purposes, and reliability is improved when using an average across several evaluators. Ratings using audio-only recordings may be more challenging when rating less experienced teachers.

Contemporary management of pain in cirrhosis: Toward precision therapy for pain

Chronic pain is highly prevalent in patients with cirrhosis and is associated with poor health-related quality of life and poor functional status. However, there is limited guidance on appropriate pain management in this population, and pharmacologic treatment can be harmful, leading to adverse outcomes, such as gastrointestinal bleeding, renal injury, falls, and hepatic encephalopathy. Chronic pain can be categorized mechanistically into three pain types: nociceptive, neuropathic, and nociplastic, each responsive to different therapies. By discussing the identification, etiology, and treatment of these three mechanistic pain descriptors with a focus on specific challenges in patients with cirrhosis, we provide a framework for better tailoring treatments, including nonpharmacologic therapies, to patients' needs.

The Mindful Reappraisal of Pain Scale (MRPS): Validation of a New Measure of Psychological Mechanisms of Mindfulness-Based Analgesia

Objectives

Mindfulness is theorized to decrease the affective amplification of chronic pain by facilitating a shift from emotionally-laden, catastrophic pain appraisals of nociceptive input to reappraising chronic pain as an innocuous sensory signal that does not signify harm. Understanding of these hypothetical psychological mechanisms of mindfulness-based analgesia has been limited by a lack of direct measures. We conducted a series of psychometric and experimental studies to develop and validate the Mindful Reappraisal of Pain Sensations Scale (MPRS).

Methods

After item generation, we conducted exploratory and confirmatory factor analyses of the MRPS in samples of opioid-treated chronic pain patients both before (n=450; n=90) and after (n=222) participating in Mindfulness-Oriented Recovery Enhancement (MORE). We then examined the convergent and divergent validity of the MRPS. Finally, in data from a randomized clinical trial (n=250), the MRPS was tested as a mediator of the effects of MORE on reducing chronic pain severity.

Results

Exploratory and confirmatory factor analyses demonstrated the single-factor structure of the MRPS. The MRPS also evidenced convergent and divergent validity. Mindfulness training through MORE significantly increased MRPS scores relative to supportive psychotherapy (F4,425.03 = 16.15, p < .001). Changes in MRPS scores statistically mediated the effect of MORE on reducing chronic pain severity through 9-month follow-up.

Conclusions

Taken together, these studies demonstrate that the MRPS is a psychometrically sound and valid measure of novel analgesic mechanisms of mindfulness including attentional disengagement from affective pain appraisals and interoceptive exposure to pain sensations.

A Brief Measure of Fidelity for Mindfulness Programs: Development and Evaluation of the Concise Fidelity for Mindfulness-Based Interventions Tool

Background

Mindfulness research and clinical programs are widespread, and it is important that mindfulness-based interventions are delivered with fidelity, or as intended, across settings. The MBI:TAC is a comprehensive system for assessing teacher competence, yet it can be complex to implement. A standardized, simple fidelity/engagement tool to address treatment delivery is needed.

Objective

We describe the development, evaluation, and outcomes of a brief, practical tool for assessing fidelity and engagement in online mindfulness-based programs. The tool contains questions about session elements such as meditation guidance and group discussion, and questions about participant engagement and technology-based barriers to engagement.

Methods

The fidelity rating tool was developed and tested in OPTIMUM, Optimizing Pain Treatment in Medical settings Using Mindfulness. The OPTIMUM study is a 3-site pragmatic randomized trial of group medical visits and adapted mindfulness-based stress reduction for primary care patients with chronic low back pain, delivered online. Two trained study personnel independently rated 26 recorded OPTIMUM sessions to determine inter-rater reliability of the Concise Fidelity for Mindfulness-Based Interventions (CoFi-MBI) tool. Trained raters also completed the CoFi-MBI for 105 sessions. Raters provided qualitative data via optional open text fields within the tool.

Results

Inter-rater agreement was 77-100% for presence of key session components, and 69-88% for Likert ratings of participant engagement and challenges related to technology, with discrepancies only occurring within 2 categories: 'very much' and 'quite a bit'. Key session components occurred as intended in 94-100% of the 105 sessions, and participant engagement was rated as 'very much' or 'quite a bit' in 95% of the sessions. Qualitative analysis of rater comments revealed themes related to engagement challenges and technology failures.

Conclusion

The CoFi-MBI provides a practical way to assess basic adherence to online delivery of mindfulness session elements, participant engagement, and extent of technology obstacles. Optional text can guide strategies to improve engagement and reduce technology barriers.

Potential novel therapeutic strategies for neuropathic pain

Purpose

To explore the potential therapeutic strategies of different types of neuropathic pain (NP) and to summarize the cutting-edge novel approaches for NP treatment based on the clinical trials registered on ClinicalTrials.gov.

Methods

The relevant clinical trials were searched using ClinicalTrials.gov Dec 08, 2022. NP is defined as a painful condition caused by neurological lesions or diseases. All data were obtained and reviewed by the investigators to confirm whether they were related to the current topic.

Results

A total of 914 trials were included in this study. They were divided into painful diabetic neuropathy (PDN), postherpetic neuralgia (PHN), sciatica (SC), peripheral nerve injury-related NP (PNI), trigeminal neuralgia (TN), chemotherapy-induced NP (CINP), general peripheral NP (GPNP) and spinal cord injury NP (SCI-NP). Potential novel therapeutic strategies, such as novel drug targets and physical means, were discussed for each type of NP.

Conclusion

NP treatment is mainly dominated by drug therapy, and physical means have become increasingly popular. It is worth noting that novel drug targets, new implications of conventional medicine, and novel physical means can serve as promising strategies for the treatment of NP. However, more attention needs to be paid to the challenges of translating research findings into clinical practice.

Designing voice interfaces to support mindfulness-based pain management

Objective

Chronic pain is a critical public health issue affecting approximately 20% of the adult population in the United States. Given the opioid crisis, there has been an urgent focus on non-addictive pain management methods including mindfulness-based stress reduction (MBSR). Prior work has successfully used MBSR for pain management. However, ensuring longitudinal engagement in MBSR practices remains a serious challenge. In this work, we explore the utility of a voice interface to support MBSR home practice.

Methods

We interviewed 10 mindfulness program facilitators to understand how such a technology might fit in the context of the MBSR class and identify potential usability issues with our prototype. We then used directed content analysis to identify key themes and sub-themes within the interview data.

Results

Our findings show that facilitators supported the use of the voice interface for MBSR, particularly for individuals with limited motor function. Facilitators also highlighted the unique affordances of voice interfaces, including perceived social presence, to support sustained engagement.

Conclusion

We demonstrate the acceptability of a voice interface to support home practice for MBSR participants among trained mindfulness facilitators. Based on our findings, we outline design recommendations for technologies aiming to provide longitudinal support for mindfulness-based interventions. Future work should further these efforts toward making non-addictive pain management interventions accessible and efficacious for a wide audience of users.

Feasibility and Acceptability of a Group-Based Mindfulness Intervention for Sexual Interest/Arousal Disorder Following Breast Cancer Treatment

This study aimed to assess feasibility and preliminary efficacy of an 8-week Mindfulness-Based Cognitive Therapy (MBCT) group program to treat Sexual Interest/Arousal Disorder (SIAD) in women following breast cancer (BrCa) treatment. Thirty women participated, of whom 67% (n = 20) attended at least 6 of 8 group sessions. Feedback indicated the program was relevant and valuable; minor modifications were suggested to further address survivorship concerns. Results of pre-post questionnaires demonstrated significant improvements in sexual distress and sexual interest/desire, with large effect sizes. Results support the feasibility and preliminary efficacy of an 8-week MBCT program among women following breast cancer treatment.

Is the combination of exercise therapy and health education more effective than usual medical care in the prevention of non-specific back pain? A systematic review with meta-analysis

BACKGROUND

Clinical practice guidelines emphasize the importance of the prevention and treatment of non-specific back pain through exercise therapy and health education. However, it has not yet been confirmed that the combination of exercise plus education is more effective than usual medical care.

OBJECTIVE

The aim of this study was to determine if the combination of exercise plus education is more effective for the prevention of non-specific back pain than usual medical care.

MATERIALS AND METHODS

A systematic search in PubMed, Scopus, Web of Science and Medline was conducted with the terms Back Pain, Neck Pain, Musculoskeletal Pain, Exercise, Exercise Therapy, Health Education, Cognitive Behavioral Therapy, Primary Prevention, Secondary Prevention and Clinical Trial. The inclusion criteria were: articles published from 2016 to 2021, the intervention included exercise and education, and the sample consisted of non-specific back pain patients.

RESULTS

A total of 4 randomized controlled trials were selected (average PEDro score 6.5 points). The meta-analysis showed statistically significant differences in the pain intensity, standardized mean differences was found to be -0.75 (95% CI = -1.41 to -0.08; p = 0.03); and in disability, standardized mean differences was found to be -0.24 (95% CI = -0.38 to -0.1; p = 0.001).

CONCLUSIONS

Interventions combining exercise and education seem to have a greater preventive effect on non-specific back pain than usual medical care.Key messagesExercise therapy and health education combination prevent better non-specific back pain than usual care.Combining exercise with educational interventions has a higher improvement on disability and kinesophobia than usual care.

"Pain, Stress, and Emotions": Uncontrolled trial of a single-session, telehealth, emotional awareness and expression therapy class for patients with chronic pain

Objectives

Trauma- and emotion-focused chronic pain interventions, particularly Emotional Awareness and Expression Therapy (EAET), show much promise for reducing pain and improving functioning. We developed a novel, single-session, telehealth-delivered EAET class ("Pain, Stress, and Emotions"; PSE) and tested it on adults with chronic pain of mixed etiology.

Methods

After an initial developmental phase, we conducted an uncontrolled trial, providing PSE to 74 individuals with chronic pain (63.5% female; 64.9% White; 60.8% with pain duration >5 years) in four class administrations. Participants completed self-report measures (primary outcomes: pain intensity and pain interference) at baseline and multiple follow-ups to 12 weeks. Linear mixed-models examined changes over time, and effect sizes were calculated on change from baseline to 4-week (primary endpoint) and 12-week follow-ups. The trial was registered with clinicaltrials.gov (NCT05014126).

Results

Participants reported high satisfaction with the PSE class. Pain intensity showed a significant, medium reduction across time (p < .001; d = 0.60 at 4 weeks); one-quarter of participants had clinically meaningful pain reduction (≥30%). Pain interference had a large reduction (p < .001; d = 0.74). There were significant but smaller improvements in most secondary outcomes (ds = 0.15 to 0.55; ps < .01). Effects were generally maintained or increased at 12-week follow-up. Higher education and baseline ambivalence over emotional expression predicted greater pain reductions.

Conclusions

People taking this EAET class had reduced pain severity and interference and improvements in other pain-related outcomes. The single-session, telehealth class holds promise as an easily delivered, efficient, and potentially impactful intervention for some patients with chronic pain, although controlled trials are needed.

Self-Guided Smartphone Application to Manage Chronic Musculoskeletal Pain: A Randomized, Controlled Pilot Trial

OBJECTIVE

The goal of this study is to evaluate the feasibility and efficacy of an auricular point acupressure smartphone app (mAPA) to self-manage chronic musculoskeletal pain.

METHODS

A prospective, longitudinal, randomized, controlled pilot trial was conducted using a three-group design (self-guided mAPA (n = 14); in-person mAPA (n = 12); and control (n = 11)). The primary outcomes included physical function and pain intensity.

RESULTS

After a 4-week APA intervention, participants in the in-person mAPA group had improved physical function of 32% immediately post-intervention and 29% at the 1M follow-up. Participants in the self-guided mAPA group had higher improvement (42% at post-intervention and 48% at the 1M follow-up). Both mAPA groups had similar degrees of pain intensity relief at post-intervention (45% for in-person and 48% for the self-guided group) and the 1M follow-up (42% for in-person and 45% for the self-guided group). Over 50% of the participants in each group reached at least 30% reduced pain intensity at post-intervention, and this was sustained in the mAPA groups at the 1M follow-up. Approximately 80% of the participants in both mAPA groups were satisfied with the treatment outcomes and adhered to the suggested APA practice; however, participants in the self-guided group had higher duration and more frequency in APA use. The attrition rate was 16% at the 1M follow-up. No adverse effects of APA were reported, and participants found APA to be beneficial and the app to be valuable.

CONCLUSIONS

The study findings indicate that participants effectively learned APA using a smartphone app, whether they were self-guided or received in-person training. They were able to self-administer APA to successfully manage their pain. Participants found APA to be valuable in their pain self-management and expressed satisfaction with the intervention using the app.

Association of non-chronic low back pain with physical function, endurance, fatigability, and quality of life in middle- and older-aged adults: Findings from Baltimore Longitudinal Study of Aging

Low back pain (LBP) is an important condition associated with high healthcare burden. However, the relationship of this condition with physical function (PF) and health-related quality of life (HRQoL) remains unclear. This is a cross-sectional study that aims to investigate the association between presence and intensity of non-chronic LBP with PF and HRQoL in middle-and older-aged adults. Participants answered questions about presence and intensity of LBP in the previous year, self-reported their PF and HRQoL (SF-12), and underwent objective measures of PF ([ExSPPB] including usual gait speed, narrow walk, chair stands, and standing balance), endurance performance ([EP] long-distance corridor walk) and fatigability. Generalized linear models and logistic regression models were performed. A total of 1500 participants (52.5% women, 70.3% white) aged 69.0 (SD 13.1) years were included. Of those, 642 (42.8%) reported LBP and the mean pain intensity was 4.1 (SD 2.2). After adjustments for potential confounders, presence of LBP was associated with lower self-reported PF (OR 1.73, 95% CI 1.27 to 2.37), lower physical component of HRQoL (β -0.03, 95% CI -0.04 to -0.02) and poorer chair stand performance (β -0.05, 95% CI -0.09 to -0.008). Higher intensity of LBP was associated with lower physical component of HRQoL (β -0.01, 95% CI -0.02 to -0.007), poorer ExSPPB performance (β -0.01, 95% CI -0.02 to -0.004), slower usual gait speed (β -0.01, 95% CI -0.02 to -0.004), lower total standing balance time (β -0.01, 95% CI -0.02 to -0.001) and higher fatigability (OR 1.13, 95% CI 1.01 to 1.25). The presence of non-chronic LBP was more consistently associated with lower self-reported PF, while higher intensity non-chronic LBP was associated with poorer objectively measured PF and fatigability. Collectively, this evidence suggests that although presence of pain may affect perception of function, greater pain intensity appears more strongly associated with unfavorable functional performance in mid-to-late life.

The effect of mindfulness on the inflammatory, psychological and biomechanical domains of adult patients with low back pain: A randomized controlled clinical trial

Objective

This study aims to study the effect of mindfulness-based program on the psychological, biomechanical and inflammatory domains of patients with chronic low back pain.

Methods

A multicentre randomized and controlled clinical trial of parallel groups in patients with chronic low back pain between March 2019 to March 2020. Participants with no experience in mindfulness based intervention, were randomized to receive (36 patients) or not (34 patients) mindfulness-based stress reduction program for chronic back pain (MBSR-CBP). The program was performed in 9 sessions. Patients with chronic low back pain due to symptomatic discopathy (degenerative disc disease or herniated disc) were included. The principal outcome was changes in the blood level of cortisol and cytokines (tumor necrosis factor- α (TNF- α), interleukin-1β (IL-1β), interleukin-6 (IL-6) and interleukin-17 (IL-17)). Secondary outcomes (psychological factors, pain, and quality of life) were measured by validated questionnaires.

Results

Of the 96 randomized patients, 70 who completed the study were included in the analysis (mean [range] age: 53 [33–73] years; 66% females). MBSR-CBP stopped the increase in cortisol, and reduced pro-inflammatory cytokine IL-1β (p = 0.05). It reduced depression (p = 0.046) and stress (p = 0.0438), perceived pain (p < 0.0001), and limitations related to health (p < 0.0001). It also increased the physical function (p = 0.002) and sleep quality (p = 0.05). Furthermore, it significantly increased life satisfaction (0.006), well-being (p = 0.001) and vitality (p < 0.0001). It also increased self-compassion (p < 0.0001) and significantly reduced the overidentification (p<0.0001) and catastrophization (p = 0.002).

Conclusions

MBSR-CBP could be part of a multidisciplinary approach in the management of patients suffering from chronic low back pain.

The effectiveness of mindfulness-based stress reduction intervention on physical function in individuals with chronic low back pain: Systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Mindfulness-based stress reduction (MBSR) is often used as a complementary treatment for chronic low back pain (CLBP), but its effects on the physical function component of the outcome are not addressed. This systematic review aims to examine the effectiveness of MBSR on outcomes of physical functions in CLBP individuals.

METHODS

Databases searched included PubMed/MEDLINE, PEDro, The Cochrane Database of Systematic Reviews, Web of Science, Scopus, CINAHL, Embase, and other sources (Google Scholar, ProQuest, Research Gate) from inception to January 2022. Randomized controlled trials (RCTs) comparing MBSR with additional interventions that evaluated physical function among CLBP individuals were included. Two independent reviewers performed data extraction. The risk of bias was assessed using the Cochrane risk-of-bias tool.

RESULTS

Six RCTs involving CLBP individuals were eligible for review. The between-group differences in RMDQ for the MBSR therapies against comparator therapies were significant at eight weeks follow-up (3 RCTs; MD, -1.28 [CI, -2.04 to -0.53]) and six months follow-up (2 RCTs; MD, -0.16 [CI, -1.01 to 0.69]).

CONCLUSION

MBSR therapy improves physical function at 8 weeks and 6 months follow-up in CLBP individuals. Further high-quality RCTs are warranted for the long-term effect of MBSR therapy on physical function outcomes.

Best Practices for Chiropractic Management of Adult Patients With Mechanical Low Back Pain: A Clinical Practice Guideline for Chiropractors in the United States

OBJECTIVE

The purpose of this paper was to update the previously published 2016 best-practice recommendations for chiropractic management of adults with mechanical low back pain (LBP) in the United States.

METHODS

Two experienced health librarians conducted the literature searches for clinical practice guidelines and other relevant literature, and the investigators performed quality assessment of included studies. PubMed was searched from March 2015 to September 2021. A steering committee of 10 experts in chiropractic research, education, and practice used the most current relevant guidelines and publications to update care recommendations. A panel of 69 experts used a modified Delphi process to rate the recommendations.

RESULTS

The literature search yielded 14 clinical practice guidelines, 10 systematic reviews, and 5 randomized controlled trials (all high quality). Sixty-nine members of the panel rated 38 recommendations. All but 1 statement achieved consensus in the first round, and the final statement reached consensus in the second round. Recommendations covered the clinical encounter from history, physical examination, and diagnostic considerations through informed consent, co-management, and treatment considerations for patients with mechanical LBP.

CONCLUSION

This paper updates a previously published best-practice document for chiropractic management of adults with mechanical LBP.

Effects of hypnosis vs mindfulness meditation vs education on chronic pain intensity and secondary outcomes in veterans: a randomized clinical trial

ABSTRACT

Effective, rigorously evaluated nonpharmacological treatments for chronic pain are needed. This study compared the effectiveness of training in hypnosis (HYP) and mindfulness meditation (MM) with an active education control (ED). Veterans (N = 328) were randomly assigned to 8 manualized, group-based, in-person sessions of HYP (n = 110), MM (n = 108), or ED (n = 110). Primary (average pain intensity [API]) and secondary outcomes were assessed at pretreatment, posttreatment, and 3 and 6 months posttreatment. Treatment effects were evaluated using linear regression, a generalized estimating equation approach, or a Fisher exact test, depending on the variable. There were no significant omnibus between-group differences in pretreatment to posttreatment change in API; however, pretreatment to posttreatment improvements in API and several secondary variables were seen for participants in all 3 conditions. Participation in MM resulted in greater decreases in API and pain interference at 6 months posttreatment relative to ED. Participation in HYP resulted in greater decreases in API, pain interference, and depressive symptoms at 3 and 6 months posttreatment compared with ED. No significant differences on outcomes between HYP and MM were detected at any time point. This study suggests that all 3 interventions provide posttreatment benefits on a range of outcomes, but the benefits of HYP and MM continue beyond the end of treatment, while the improvements associated with ED dissipate over time. Future research is needed to determine whether the between-group differences that emerged posttreatment are reliable, whether there are benefits of combining treatments, and to explore moderating and mediating factors.

An Overview of Mindfulness-Oriented Addiction and Pain Recovery

There is evidence that mindfulness-based interventions are effective as stress-reduction techniques in people with various stressor-related disorders. Research also shows overall improvement in mental health well-being in practitioners of mindfulness. However, there is limited literature probing the potential negative impacts of mindfulness practice. Relapse is a major challenge in substance use disorders (SUDs), particularly for people with chronic pain. There is an overlap between SUDs and chronic pain, which share common pathophysiological pathways that could contribute to poor pain control and mental instability. In this report, we discuss the possible effects of mindfulness on specified aspects of substance craving and chronic pain perception. We propose future directions for research in mindfulness practices to maximize the potential for relapse prevention and pain control.

Mindfulness-Based Stress Reduction, Cognitive Behavioral Therapy, and Acupuncture in Chronic Low Back Pain: Protocol for Two Linked Randomized Controlled Trials

BACKGROUND

Nonpharmacologic mind-body therapies have demonstrated efficacy in low back pain. However, the mechanisms underlying these therapies remain to be fully elucidated.

OBJECTIVE

In response to these knowledge gaps, the Stanford Center for Low Back Pain-a collaborative, National Institutes of Health P01-funded, multidisciplinary research center-was established to investigate the common and distinct biobehavioral mechanisms of three mind-body therapies for chronic low back pain: cognitive behavioral therapy (CBT) that is used to treat pain, mindfulness-based stress reduction (MBSR), and electroacupuncture. Here, we describe the design and implementation of the center structure and the associated randomized controlled trials for characterizing the mechanisms of chronic low back pain treatments.

METHODS

The multidisciplinary center is running two randomized controlled trials that share common resources for recruitment, enrollment, study execution, and data acquisition. We expect to recruit over 300 chronic low back pain participants across two projects and across different treatment arms within each project. The first project will examine pain-CBT compared with MBSR and a wait-list control group. The second project will examine real versus sham electroacupuncture. We will use behavioral, psychophysical, physical measure, and neuroimaging techniques to characterize the central pain modulatory and emotion regulatory systems in chronic low back pain at baseline and longitudinally. We will characterize how these interventions impact these systems, characterize the longitudinal treatment effects, and identify predictors of treatment efficacy.

RESULTS

Participant recruitment began on March 17, 2015, and will end in March 2023. Recruitment was halted in March 2020 due to COVID-19 and resumed in December 2021.

CONCLUSIONS

This center uses a comprehensive approach to study chronic low back pain. Findings are expected to significantly advance our understanding in (1) the baseline and longitudinal mechanisms of chronic low back pain, (2) the common and distinctive mechanisms of three mind-body therapies, and (3) predictors of treatment response, thereby informing future delivery of nonpharmacologic chronic low back pain treatments.

Pain Education in the Management of Patients with Chronic Low Back Pain: A Systematic Review

New prospective of chronic low back pain (CLBP) management based on the biopsychosocial model suggests the use of pain education, or neurophysiological pain education, to modify erroneous conceptions of disease and pain, often influenced by fear, anxiety and negative attitudes. The aim of the study is to highlight the evidence on the outcomes of a pain education-oriented approach for the management of CLBP. The search was conducted on the Pubmed, Scopus, Pedro and Cochrane Library databases, leading to 2673 results until September 2021. In total, 13 articles published in the last 10 years were selected as eligible. A total of 6 out of 13 studies support a significant reduction in symptoms in the medium term. Disability is investigated in only 11 of the selected studies, but 7 studies support a clear reduction in the medium-term disability index. It is difficult to assess the effectiveness of the treatments of pain education in patients affected by CLBP, due to the multimodality and heterogeneity of the treatments administered to the experimental group. In general, methods based on pain education or on cognitive-behavioral approaches, in association with physical therapy, appear to be superior to physiotherapeutic interventions alone in the medium term.
