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

Recruitment, retention, and adherence in a randomized feasibility trial of mindfulness-based stress reduction for patients with migraine

OBJECTIVES

Increasing evidence demonstrates effectiveness of Mindfulness-Based Stress Reduction (MBSR) for pain-related and functional disorders. In order to conduct successful and efficient trials of MBSR, evidence regarding the relative performance of strategies to improve recruitment, retention, and adherence is required, but few studies have examined these issues specifically.

DESIGN

In preparation for a fully powered trial, we conducted a 2-arm, parallel comparison randomized controlled feasibility trial of MBSR vs. usual-care for 60 patients with migraine headache.

SETTING

Two large U.S. health systems in Northern California.

INTERVENTION

MBSR is an 8-week classroom-based intervention that combines mindfulness meditation and yoga, with didactic presentations about stress psychology and group process/experiential education. Participants received the intervention at their choice of one of several existing, vetted community-based classes.

MAIN OUTCOME MEASURES

Successful recruitment was defined a priori as 18 participants within any 9-week period or 60 participants enrolled within a 36-week period. We considered participants adherent to the intervention if they attended at least 5 of the 8 weekly classes and the day-long retreat.

RESULTS

We successfully enrolled 18 participants within a 7-week period, however, we did not attain our second goal of recruiting 60 participants within a 36-week period. Sixty-eight percent of our participants were adherent to the intervention.

CONCLUSIONS

We found that close monitoring of recruitment activities, flexibility in protocol modifications, and integration within the delivery system were crucial factors for successful participant recruitment, retention, and adherence in mindfulness research.

Effectiveness of an alternative intervention in the treatment of depressive symptoms

BACKGROUND

There is a scarcity of studies in the international literature regarding alternative treatment to the pharmacological and psychotherapeutic intervention in the face of depression symptoms. This study aimed to test a protocol based on natural therapy, alternatives to pharmacological and psychotherapeutic, through Mindfulness Meditation, Reiki, Acupuncture and Auriculotherapy, to treat the symptoms of depression for those who were with no pharmacological or psychotherapeutic treatment for these symptoms.

METHODS

this is a randomized single-blind controlled pilot study. The final sample was 21 participants divided in two groups: experimental and control. Participants were evaluated by validated instruments during the screening process and after the intervention. The instruments were: Depression, Anxiety and Stress Scale and Beck Depression Inventory. Intervention was performed in eight sessions, during two months. All the techniques were used in the experimental group. Analysis of variance with repeated measures was used to compare pre-intervention to post-intervention moments.

RESULTS

the result of analysis indicates a significant reduction in the symptoms of depression after the intervention among the experimental group.

LIMITATIONS

there is no way to determine which of the techniques used produced the most significant result.

CONCLUSIONS

The protocol proposed in this study was effective in reducing the symptoms of depression to whom are not eligible for traditional treatment.

Feasibility and Acceptability of an Abbreviated, Four-Week Mindfulness Program for Chronic Pain Management

OBJECTIVE

The Mindfulness-Based Stress Reduction program is effective at improving chronic pain outcomes, but the time demand hinders participation. This preliminary study evaluated the feasibility, acceptability, and potential effects of providing an abbreviated mindfulness program for patients with chronic pain.

DESIGN

A single-arm, mixed-methods, pre-post intervention study.

SETTING

An outpatient rehabilitation clinic at an academic medical center.

SUBJECTS

Participants were N = 23 adults with chronic pain who were new to mindfulness practice.

METHODS

Mindfulness-based Stress Reduction was adapted to shorten the program to four weekly 90-minute sessions and to focus content on pain management. Three cohorts of six to nine participants completed baseline and post-treatment measures of 1) patient-reported outcomes, including pain intensity, pain interference, physical functioning, depressive/anxiety symptoms, positive affect and well-being, and sleep disturbance; 2) pain medication dosages; 3) psychosocial variables including pain acceptance, pain catastrophizing, and perceived stress; 4) dispositional mindfulness, as well as postintervention structured interviews about their experiences.

RESULTS

Acceptable rates of retention and attendance and high ratings of satisfaction indicated that the intervention was feasible and acceptable. In interviews, participants found the program acceptable and beneficial and provided suggestions to improve it. From pre- to post-treatment, significant improvements were reported in all measures except physical functioning and anxiety.

CONCLUSIONS

In adults with chronic pain, a four-week mindfulness program is feasible and acceptable, addresses the barrier of a lengthy program, and may improve quality of life and psychological functioning. An appropriately powered randomized controlled trial with a comparison group is needed to assess the intervention's effectiveness.

Efficacy and acceptability of mindfulness-based interventions for military veterans: A systematic review and meta-analysis

BACKGROUND

Military veterans report high rates of psychiatric and physical health symptoms that may be amenable to mindfulness-based interventions (MBIs). Inconsistent prior findings and questions of fit between MBIs and military culture highlight the need for a systematic evaluation of this literature.

OBJECTIVE

To quantify the efficacy and acceptability of MBIs for military veterans.

DATA SOURCES

We searched five databases (MEDLINE/PubMed, CINAHL, Scopus, Web of Science, PsycINFO) from inception to October 16th, 2019.

STUDY SELECTION

Randomized controlled trials (RCTs) testing MBIs in military veterans.

RESULTS

Twenty studies (k = 16 unique comparisons, N = 898) were included. At post-treatment, MBIs were superior to non-specific controls (e.g., waitlist, attentional placebos) on measures of posttraumatic stress disorder (PTSD), depression, general psychological symptoms (i.e., aggregated across symptom domains), quality of life / functioning, and mindfulness (Hedges' gs = 0.32 to 0.80), but not physical health. At follow-up (mean length = 3.19 months), MBIs continued to outperform non-specific controls on general psychological symptoms, but not PTSD. MBIs were superior to specific active controls (i.e., other therapies) at post-treatment on measures of PTSD and general psychological symptoms (gs = 0.19 to 0.25). Participants randomized to MBIs showed higher rates of attrition than those randomized to control interventions (odds ratio = 1.98). Several models were not robust to tests of publication bias. Study quality and risk of bias assessment indicated several areas of concern.

CONCLUSIONS

MBIs may improve psychological symptoms and quality of life / functioning in veterans. Questionable acceptability and few high-quality studies support the need for rigorous RCTs, potentially adapted to veterans.

Systematic scoping review of interactions between analgesic drug therapy and mindfulness-based interventions for chronic pain in adults: current evidence and future directions

Most patients with chronic pain do not find adequate pain relief with a single treatment, and accumulating evidence points to the added benefits of rational combinations of different treatments. Given that psychological therapies, such as mindfulness-based interventions (MBIs), are often delivered in conjunction with concomitant analgesic drug therapies (CADTs), this systematic scoping review examines the evidence for any interactions between MBIs and CADTs. The protocol for this review has been published and registered. MEDLINE, Cochrane Central Register of Controlled Trials, EMBASE, and PsycINFO databases were searched until July 2019. We included randomized controlled trials that evaluated the efficacy of MBIs for the treatment of chronic pain. A total of 40 randomized controlled trials (2978 participants) were included. Thirty-nine of 40 (97.5%) included mindfulness-based clinical trials allowed the use of CADTs. However, only 6 of these 39 (15.4%) trials provided adequate details of what these CADTs were, and only 4 (10.3%) trials controlled for CADTs. Of great relevance to this review, none of the included trials analyzed the interactions between MBIs and the CADTs to determine whether they have an additive, synergistic, or antagonistic effect on chronic pain. Adverse events were inconsistently reported, and no judgment could be made about safety. Future trials assessing the interactions between MBIs and CADTs, with better harms reporting, are needed to better define the role of MBIs in the management of chronic pain.

Differential efficacy between cognitive-behavioral therapy and mindfulness-based therapies for chronic pain: Systematic review

Background/Objective: To assess the differential efficacy between mindfulness-based interventions and cognitive-behavioral Therapy (CBT) on chronic pain across medical conditions involving pain. Method: ProQuest, Science Direct, Google Scholar, Pubmed, and Embase databases were searched to identify randomized clinical trials. Measurements of mindfulness, pain, mood, and further miscellaneous measurements were included. Results: 18 studies met the inclusion criteria (fibromyalgia, n = 5; low back pain, n = 5; headache/migraine, n = 4; non-specific chronic pain, n = 4). In fibromyalgia, mindfulness based stress reduction (MBSR) was superior to the usual care and Fibroqol, in impact and symptoms. In low back pain, MBSR was superior to the usual care, but not to CBT, in physical functionality and pain intensity. There were no studies on differential efficacy between mindfulness and CBT for headache and non-specific chronic pain, but Mindfulness interventions were superior to the usual care in these syndromes. Conclusions: Mindfulness interventions are superior to usual cares in all diagnoses, but it is not possible to conclude their superiority over CBT. Comparisons between mindfulness interventions are scarce, with MBSR being the most studied. In central sensitization syndromes, variables associated with pain tend to improve with treatment. More research is needed to differentiate diagnosis and intervention.

Cost-effectiveness of Yoga for Chronic Low Back Pain in Veterans

BACKGROUND

Yoga interventions can improve function and reduce pain in persons with chronic low back pain (cLBP).

OBJECTIVE

Using data from a recent trial of yoga for military veterans with cLBP, we analyzed the incremental cost-effectiveness of yoga compared with usual care.

METHODS

Participants (n=150) were randomized to either 2× weekly, 60-minute yoga sessions for 12 weeks, or to delayed treatment (DT). Outcomes were measured at 12 weeks, and 6 months. Quality-adjusted life years (QALYs) were measured using the EQ-5D scale. A 30% improvement on the Roland-Morris Disability Questionnaire (primary outcome) served as an additional effectiveness measure. Intervention costs including personnel, materials, and transportation were tracked during the study. Health care costs were obtained from patient medical records. Health care organization and societal perspectives were examined with a 12-month horizon.

RESULTS

Incremental QALYs gained by the yoga group over 12 months were 0.043. Intervention costs to deliver yoga were $307/participant. Negligible differences in health care costs were found between groups. From the health care organization perspective, the incremental cost-effectiveness ratio to provide yoga was $4488/QALY. From the societal perspective, yoga was "dominant" providing both health benefit and cost savings. Probabilistic sensitivity analysis indicates an 89% chance of yoga being cost-effective at a willingness-to-pay of $50,000. A scenario comparing the costs of yoga and physical therapy suggest that yoga may produce similar results at a much lower cost.

DISCUSSION/CONCLUSIONS

Yoga is a cost-effective treatment for reducing pain and disability among military veterans with cLBP.

Effects of hypnosis, cognitive therapy, hypnotic cognitive therapy, and pain education in adults with chronic pain: a randomized clinical trial

Chronic pain is a significant health problem worldwide with limited pharmacological treatment options. This study evaluated the relative efficacy of 4 treatment sessions each of 4 nonpharmacological treatments: (1) hypnotic cognitive therapy (using hypnosis to alter the meaning of pain); (2) standard cognitive therapy; (3) hypnosis focused on pain reduction, and (4) pain education. One hundred seventy-three individuals with chronic pain were randomly assigned to receive 4 sessions of 1 of the 4 treatments. Primary (pain intensity) and secondary outcome measures were administered by assessors unaware of treatment allocation at pretreatment, posttreatment, and 3-, 6-, and 12-month follow-up. Treatment effects were evaluated using analysis of variance, a generalized estimating equation approach, or a Fisher exact test, depending on the outcome domain examined. All 4 treatments were associated with medium to large effect size improvements in pain intensity that maintained up to 12 months posttreatment. Pretreatment to posttreatment improvements were observed across the 4 treatment conditions on the secondary outcomes of pain interference and depressive symptoms, with some return towards pretreatment levels at 12-month follow-up. No significant between-group differences emerged in omnibus analyses, and few statistically significant between-group differences emerged in the planned pairwise analyses, although the 2 significant effects that did emerge favored hypnotic cognitive therapy. Future research is needed to determine whether the significant differences that emerged are reliable.

Update of Markov Model on the Cost-effectiveness of Nonpharmacologic Interventions for Chronic Low Back Pain Compared to Usual Care

STUDY DESIGN

Markov model.

OBJECTIVE

Further validity test of a previously published model.

SUMMARY OF BACKGROUND DATA

The previous model was built using data from ten randomized trials and examined the 1-year effectiveness and cost-effectiveness of 17 nonpharmacologic interventions for chronic low back pain (CLBP), each compared to usual care alone. This update incorporated data from five additional trials.

METHODS

Based on transition probabilities that were estimated using patient-level trial data, a hypothetical cohort of CLBP patients transitioned over time among four defined health states: high-impact chronic pain with substantial activity limitations; higher (moderate-impact) and lower (low-impact) pain without activity limitations; and no pain. As patients transitioned among health states, they accumulated quality-adjusted life-years, as well as healthcare and productivity costs. Costs and effects were calculated incremental to each study's version of usual care.

RESULTS

From the societal perspective and assuming a typical patient mix (25% low-impact, 35% moderate-impact, and 40% high-impact chronic pain), most interventions-including those newly added-were cost-effective (<$50,000/QALY) and demonstrated cost savings. From the payer perspective, fewer were cost-saving, but the same number were cost-effective. Results for the new studies generally mirrored others using the same interventions-for example, cognitive behavioral therapy (CBT) and physical therapy. A new acupuncture study had similar effectiveness to other acupuncture studies, but higher usual care costs, resulting in higher cost savings. Two new yoga studies' results were similar, but both differed from those of the original yoga study. Mindfulness-based stress reduction was similar to CBT for a typical patient mix but was twice as effective for those with high-impact chronic pain.

CONCLUSION

Markov modeling facilitates comparisons across interventions not directly compared in trials, using consistent outcome measures after balancing the baseline mix of patients. Outcomes also differed by pain impact level, emphasizing the need to measure CLBP subgroups.

Mindfulness in Patients with Upper-Extremity Conditions: A Summary of Existing Literature

Mindfulness implies entering a mental state of awareness which allows for the reframing of an experience, and functionality has shown to be influenced by mindset. The aim of this systematic review was to assess effects of mindfulness in patients with upper-extremity conditions. PubMed, Embase, Cochrane, and CINAHL databases were searched on June 19, 2019, for studies investigating mindfulness in patients with upper-extremity conditions. Two validated instruments for methodologic assessment were used to assess study quality. Studies that reported pain, psychological, or functional outcome measures were included. One randomized controlled trials and three observational studies were included, which together included 335 patients that completed final follow-up. The weighted average age was 52.4 years and 48% of the patients were male. Evaluation of the outcome measures used was immediately after the mindfulness intervention or assessment in all studies. Mindfulness appeared to be positively associated with less pain (though below the minimal clinically important difference), increased mood, and better function. Mindfulness is associated with increased mood and possibly better functionality in adults with a large range of upper-extremity conditions when measured or used as an intervention. Future researcher should expand the subject as only four studies were included in this review. This is a Level IV study.

Pain relief for osteoarthritis through combined treatment (PROACT): Protocol for a randomized controlled trial of mindfulness meditation combined with transcranial direct current stimulation in non-Hispanic black and white adults with knee osteoarthritis

Knee osteoarthritis (OA) is a leading cause of late life pain and disability, and non-Hispanic black (NHB) adults experience greater OA-related pain and disability than non-Hispanic whites (NHWs). Recent evidence implicates psychosocial stress, cognitive-attentional processes, and altered central pain processing as contributors to greater OA-related pain and disability among NHBs. To address these ethnic/race disparities, this clinical trial will test whether a mindfulness intervention (Breathing and Attention Training, BAT) combined with transcranial direct current stimulation (tDCS) will enhance pain modulatory balance and pain-related brain function, reduce clinical pain, and attenuate ethnic differences therein, among NHBs and NHWs with knee OA. Participants will complete assessments of clinical pain, function, psychosocial measures, and quantitative sensory testing (QST), including mechanical temporal summation and conditioned pain modulation. Neuroimaging will be performed to examine pain-related brain structure and function. Then, participants will be randomized to one of four groups created by crossing two BAT conditions (Real vs. Sham) with two tDCS conditions (Real vs. Sham). Participants will then undergo five treatment sessions during which the assigned BAT and tDCS interventions will be delivered concurrently for 20 min over one week. After the fifth intervention session, participants will undergo assessments of clinical pain and function, QST and neuroimaging identical to the pretreatment measures, and monthly follow-up assessments of pain will be conducted for three months. This will be the first study to determine whether mindfulness and tDCS treatments will show additive or synergistic effects when combined, and whether treatment effects differ across ethnic/race groups.

Effects of Mindfulness-Oriented Recovery Enhancement Versus Social Support on Negative Affective Interference During Inhibitory Control Among Opioid-Treated Chronic Pain Patients: A Pilot Mechanistic Study

BACKGROUND

Among opioid-treated chronic pain patients, deficient response inhibition in the context of emotional distress may contribute to maladaptive pain coping and prescription opioid misuse. Interventions that aim to bolster cognitive control and reduce emotional reactivity (e.g., mindfulness) may remediate response inhibition deficits, with consequent clinical benefits.

PURPOSE

To test the hypothesis that a mindfulness-based intervention, Mindfulness-Oriented Recovery Enhancement (MORE), can reduce the impact of clinically relevant, negative affective interference on response inhibition function in an opioid-treated chronic pain sample.

METHODS

We examined data from a controlled trial comparing adults with chronic pain and long-term prescription opioid use randomized to either MORE (n = 27) treatment or to an active support group comparison condition (n = 30). Participants completed an Emotional Go/NoGo Task at pre- and post-treatment, which measured response inhibition in neutral and clinically relevant, negative affective contexts (i.e., exposure to pain-related visual stimuli).

RESULTS

Repeated-measures analysis of variance indicated that compared with the support group, participants in MORE evidenced significantly greater reductions from pre- to post-treatment in errors of commission on trials with pain-related distractors relative to trials with neutral distractors, group × time × condition F(1,55) = 4.14, p = .047, η2partial = .07. Mindfulness practice minutes and increased nonreactivity significantly predicted greater emotional response inhibition. A significant inverse association was observed between improvements in emotional response inhibition and treatment-related reductions in pain severity by 3-month follow-up.

CONCLUSIONS

Study results provide preliminary evidence that MORE enhances inhibitory control function in the context of negative emotional interference.

Mindfulness-Based Stress Reduction in the Management of Chronic Pain and Its Comorbid Depression

Context

Chronic pain (CP) is a common and serious medical condition, with an estimated 100 million people affected in the United States. In the 1990s, opioids were increasingly prescribed to manage chronic pain, and this practice contributed to the opioid epidemic of the 21st century. To combat this epidemic, multidisciplinary approaches to chronic pain management are being researched and implemented.

Objective

To evaluate the clinical effectiveness of an 8-week mindfulness-based stress reduction (MBSR) course implemented in a semi-rural population with chronic pain.

Methods

Participants were recruited from a community-based teaching hospital in Corvallis, Oregon, for a pre-post study. Participants aged 34 to 77 years who reported having chronic pain lasting for at least 1 year before enrollment were included. Participants took an 8-week group MBSR course in 2.5-hour weekly sessions taught by an experienced MBSR instructor. Techniques were self-practiced between sessions with a goal of 30 minutes per day, 6 days per week. Pre- and postsurvey measurements of pain, depression, and functional capacity were taken via online surveys using the patient health questionnaire (PHQ-9), the Pain Catastrophizing Scale (PCS), and a shortened version of the Modified Oswestry Disability Index (MO). Participants were asked about their satisfaction with the program content, instructor, timing, and location.

Results

Twenty-eight participants were included in the study. Paired t tests found significant improvements in PHQ-9, PCS, and MO percent scores from before to after the course. PHQ-9 scores decreased by a mean of 3.7 points (95% CI, −5.5, −1.8), PCS scores decreased by a mean of 4.6 points (95% CI: −7.2, −2.0), and MO percent score decreased by a mean of 9.4% (95% CI: −14.2%, −4.6%). Results showed an overall downward shift in the distribution of depression, disability, and pain scores after the course.

Conclusions

MBSR classes were found to benefit participants with chronic pain and depression in this setting, fostering significant improvement in participant perceptions of pain, mood, and functional capacity.

Optimizing a self-directed mobile mindfulness intervention for improving cardiorespiratory failure survivors' psychological distress (LIFT2): Design and rationale of a randomized factorial experimental clinical trial

INTRODUCTION

Although as many as 75% of the >2 million annual intensive care unit (ICU) survivors experience symptoms of psychological distress that persist for months to years, few therapies exist that target their symptoms and accommodate their unique needs. In response, we developed LIFT, a mobile app-based mindfulness intervention. LIFT reduced distress symptoms more than either a telephone-based mindfulness program or education control in a pilot randomized clinical trial (LIFT1).

OBJECTIVE

To describe the methods of a factorial experimental clinical trial (LIFT2) being conducted to aid in the development and implementation of the version of the LIFT intervention that is optimized across domains of effect, feasibility, scalability, and costs.

METHODS AND ANALYSIS

The LIFT2 study is an optimization trial conceptualized as a component of a larger multiphase optimization strategy (MOST) project. The goal of LIFT2 is to use a 2 × 2 × 2 factorial experimental trial involving 152 patients to determine the ideal components of the LIFT mobile mindfulness program for ICU survivors across factors including (1) study introduction by call from a therapist vs. app only, (2) response to persistent or worsening symptoms over time by therapist vs. app only, and (3) high dose vs. low dose. The primary trial outcome is change in depression symptoms 1 month from randomization measured by the PHQ-9 instrument. Secondary outcomes include anxiety, post-traumatic stress disorder, and physical symptoms; measures of feasibility, acceptability, and usability; as well as themes assessed through qualitative analysis of semi-structured interviews with study participants conducted after follow up completion. We will use general linear models to compare outcomes across the main effects and interactions of the factors.

All-Cause Opioid Prescriptions Dispensed: The Outsized Role of Adults With Arthritis

INTRODUCTION

Limited estimates of prescribed opioid use among adults with arthritis exist. All-cause (i.e., for any condition) prescribed opioid dispensed (referred to as opioid prescription in the remainder of this abstract) in the past 12 months among U.S. adults aged ≥18 years (n=35,427) were studied, focusing on adults with arthritis (n=12,875).

METHODS

In 2018-2019, estimates were generated using Medical Expenditure Panel Survey data: (1) 2015 prevalence of 1 or more opioid prescriptions to U.S. adults overall and by arthritis status and (2) in 2014-2015, among adults with arthritis, multivariable-adjusted associations between 1 or more opioid prescriptions and sociodemographic characteristics, health status, and healthcare utilization characteristics.

RESULTS

In 2015, the age-standardized prevalence of 1 or more opioid prescriptions among adults with arthritis (29.6%) was almost double of that for all adults (15.4%). Adults with arthritis represented more than half of all adults (55.3%) with at least 1 opioid prescription; among those with 1 or more prescriptions, 43.2% adults had 4 or more prescriptions. The strongest multivariable-adjusted associations with 1 or more opioid prescriptions were ambulatory care visits (1-4: prevalence ratios=1.9-2.0, 5-8: prevalence ratios=2.5-2.7, 9 or more: prevalence ratios=3.4-3.7) and emergency room visits (1: prevalence ratios=1.6, 2-3: prevalence ratios=1.9-2.0, 4 or more: prevalence ratios=2.4); Ref for both: no visits.

CONCLUSIONS

Adults with arthritis are a high-need target group for improving pain management, representing more than half of all U.S. adults with 1 or more opioid prescriptions. The association with ambulatory care visits suggests that providers have routine opportunities to discuss comprehensive and integrative pain management strategies, including low-cost evidence-based self-management approaches (e.g., physical activity, self-management education programs, cognitive behavioral therapy). Those with multiple opioid prescriptions may need extra support if transitioning to nonopioid and nonpharmacologic pain management strategies.

A Brief Report on an 8-Week Course of Mindfulness-based Care for Chronic Pain in the Treatment of Veterans With Back Pain: Barriers Encountered to Treatment Engagement and Lessons Learned

BACKGROUND

Chronic pain and associated symptoms are debilitating for veterans. Medical costs of treatments are high and current treatment options, most notably with opioid medications, have been associated with significant risk. Mindfulness-based interventions appear promising for chronic pain, but require additional testing in veteran care settings.

OBJECTIVE

This project was designed to test the feasibility of engaging and retaining veterans with chronic lower back pain in a new mindfulness protocol tailored for veterans, mindfulness-based care for chronic pain (MBCP). Clinical outcomes were also assessed.

DESIGN

An open pilot trial of an 8-week MBCP course that included meditation, gentle yoga, and psychoeducation.

SUBJECTS

Twenty-two veterans (mean age=49.77; 18% women) were recruited from a VA Medical Center in the Northeastern US. After screening for inclusion/exclusion criteria, 20 were eligible at baseline.

MEASURES

Veterans were assessed at baseline and postintervention for functional impairment, pain intensity and bothersomeness, depression, and mindfulness.

RESULTS

The average number of sessions completed was 5; only 4 (20%) attended all sessions. Eleven of the 20 participants (55%) attended 5 or more sessions and had complete preintervention and postintervention visits. Five of the 11 had a clinically meaningful decrease in pain intensity and in depressive symptoms, while 6 of 11 had a meaningful decrease in pain bothersomeness and functional impairment.

CONCLUSIONS

It was challenging to enroll and retain participants in this study, even with our intervention designed for veterans. We discuss possible adaptations and refinements in MBCP for veterans with chronic pain to enhance feasibility and improve upon these interventions.

Evaluation of the implementation of the Back Skills Training (BeST) programme using online training: a cohort implementation study

OBJECTIVES

1) Evaluate implementation of the Back Skills Training (BeST) programme, a group cognitive behavioural approach for patients with low back pain (LBP) developed for a clinical trial, into the National Health Service (NHS) in the United Kingdom; 2) Compare patient outcomes with the BeST Trial results.

DESIGN

Two stage observational cohort implementation study.

PARTICIPANTS

Stage 1: NHS Clinicians enrolled in BeST online training. Stage 2: Patients with LBP attending NHS physiotherapy departments and enrolled in the BeST programme.

INTERVENTION

An online training and implementation programme.

OUTCOMES

Stage 1: LBP attitudes and beliefs, self-rated competence, intention and actual implementation were collected before, immediately, 4- and 12-months post-training. Stage 2: Patients rated pain, function, recovery and satisfaction before and up to one year after attending the BeST programme.

RESULTS

Stage 1: 1324 clinicians (157 NHS Trusts) enrolled in the training; 586 (44%) clinicians (101 NHS Trusts) completed training; 443/586 (76%) clinicians provided post-training data; 253/443 (57%) clinicians intended to implement the programme; 148/381 (39%) clinicians (54 NHS Trusts) provided follow-up data; 49/148 (33.1%) clinicians (27 NHS Trusts) implemented the programme. Attitudes and beliefs shifted towards a biopsychosocial model post-training. Stage 2: 923 patients were enrolled. Patients reported improvements in function (mean change: 1.55; 95%CI: 1.25, 1.86) and pain (-0.84; -1.1, -0.58) at follow-up. The majority rated themselves improved and satisfied with the programme.

CONCLUSION

Online training had good reach into NHS Trusts although, not everyone went onto implement the programme. Improvements in function that were consistent with the original trial were demonstrated.

Gray Matter Changes in Adolescents Participating in a Meditation Training

Meditation has shown to benefit a wide range of conditions and symptoms, but the neural mechanisms underlying the practice remain unclear. Magnetic resonance imaging (MRI) studies have investigated the structural brain changes due to the practice by examining volume, density, or cortical thickness changes. However, these studies have focused on adults; meditation’s structural effects on the adolescent brain remain understudied. In this study, we investigated how meditation training affects the structure of the adolescent brain by scanning a group of 38 adolescents (16.48 ± 1.29 years) before and after participating in a 12-week meditation training. Subjects underwent Training for Awareness, Resilience, and Action (TARA), a program that mainly incorporates elements from mindfulness meditation and yoga-based practices. A subset of the adolescents also received an additional control scan 12 weeks before TARA. We conducted voxel-based morphometry (VBM) to assess gray matter volume changes pre- to post-training and during the control period. Subjects showed significant gray matter (GM) volume decreases in the left posterior insula and to a lesser extent in the left thalamus and left putamen after meditation training. There were no significant changes during the control period. Our results support previous findings that meditation affects regions associated with physical and emotional awareness. However, our results are different from previous morphometric studies in which meditation was associated with structural increases. We posit that this discrepancy may be due to the differences between the adolescent brain and the adult brain.

Psychological therapies for the management of chronic pain (excluding headache) in adults

BACKGROUND

Chronic non-cancer pain, a disabling and distressing condition, is common in adults. It is a global public health problem and economic burden on health and social care systems and on people with chronic pain. Psychological treatments aim to reduce pain, disability and distress. This review updates and extends its previous version, published in 2012.

OBJECTIVES

To determine the clinical efficacy and safety of psychological interventions for chronic pain in adults (age > 18 years) compared with active controls, or waiting list/treatment as usual (TAU).

SEARCH METHODS

We identified randomised controlled trials (RCTs) of psychological therapies by searching CENTRAL, MEDLINE, Embase and PsycINFO to 16 April 2020. We also examined reference lists and trial registries, and searched for studies citing retrieved trials.

SELECTION CRITERIA

RCTs of psychological treatments compared with active control or TAU of face-to-face therapies for adults with chronic pain. We excluded studies of headache or malignant disease, and those with fewer than 20 participants in any arm at treatment end.

DATA COLLECTION AND ANALYSIS

Two or more authors rated risk of bias, extracted data, and judged quality of evidence (GRADE). We compared cognitive behavioural therapy (CBT), behavioural therapy (BT), and acceptance and commitment therapy (ACT) with active control or TAU at treatment end, and at six month to 12 month follow-up. We did not analyse the few trials of other psychological treatments. We assessed treatment effectiveness for pain intensity, disability, and distress. We extracted data on adverse events (AEs) associated with treatment.

MAIN RESULTS

We added 41 studies (6255 participants) to 34 of the previous review's 42 studies, and now have 75 studies in total (9401 participants at treatment end). Most participants had fibromyalgia, chronic low back pain, rheumatoid arthritis, or mixed chronic pain. Most risk of bias domains were at high or unclear risk of bias, with selective reporting and treatment expectations mostly at unclear risk of bias. AEs were inadequately recorded and/or reported across studies. CBT The largest evidence base was for CBT (59 studies). CBT versus active control showed very small benefit at treatment end for pain (standardised mean difference (SMD) -0.09, 95% confidence interval (CI) -0.17 to -0.01; 3235 participants; 23 studies; moderate-quality evidence), disability (SMD -0.12, 95% CI -0.20 to -0.04; 2543 participants; 19 studies; moderate-quality evidence), and distress (SMD -0.09, 95% CI -0.18 to -0.00; 3297 participants; 24 studies; moderate-quality evidence). We found small benefits for CBT over TAU at treatment end for pain (SMD -0.22, 95% CI -0.33 to -0.10; 2572 participants; 29 studies; moderate-quality evidence), disability (SMD -0.32, 95% CI -0.45 to -0.19; 2524 participants; 28 studies; low-quality evidence), and distress (SMD -0.34, 95% CI -0.44 to -0.24; 2559 participants; 27 studies; moderate-quality evidence). Effects were largely maintained at follow-up for CBT versus TAU, but not for CBT versus active control. Evidence quality for CBT outcomes ranged from moderate to low. We rated evidence for AEs as very low quality for both comparisons. BT We analysed eight studies (647 participants). We found no evidence of difference between BT and active control at treatment end (pain SMD -0.67, 95% CI -2.54 to 1.20, very low-quality evidence; disability SMD -0.65, 95% CI -1.85 to 0.54, very low-quality evidence; or distress SMD -0.73, 95% CI -1.47 to 0.01, very low-quality evidence). At follow-up, effects were similar. We found no evidence of difference between BT and TAU (pain SMD -0.08, 95% CI -0.33 to 0.17, low-quality evidence; disability SMD -0.02, 95% CI -0.24 to 0.19, moderate-quality evidence; distress SMD 0.22, 95% CI -0.10 to 0.54, low-quality evidence) at treatment end. At follow-up, we found one to three studies with no evidence of difference between BT and TAU. We rated evidence for all BT versus active control outcomes as very low quality; for BT versus TAU. Evidence quality ranged from moderate to very low. We rated evidence for AEs as very low quality for BT versus active control. No studies of BT versus TAU reported AEs. ACT We analysed five studies (443 participants). There was no evidence of difference between ACT and active control for pain (SMD -0.54, 95% CI -1.20 to 0.11, very low-quality evidence), disability (SMD -1.51, 95% CI -3.05 to 0.03, very low-quality evidence) or distress (SMD -0.61, 95% CI -1.30 to 0.07, very low-quality evidence) at treatment end. At follow-up, there was no evidence of effect for pain or distress (both very low-quality evidence), but two studies showed a large benefit for reducing disability (SMD -2.56, 95% CI -4.22 to -0.89, very low-quality evidence). Two studies compared ACT to TAU at treatment end. Results should be interpreted with caution. We found large benefits of ACT for pain (SMD -0.83, 95% CI -1.57 to -0.09, very low-quality evidence), but none for disability (SMD -1.39, 95% CI -3.20 to 0.41, very low-quality evidence), or distress (SMD -1.16, 95% CI -2.51 to 0.20, very low-quality evidence). Lack of data precluded analysis at follow-up. We rated evidence quality for AEs to be very low. We encourage caution when interpreting very low-quality evidence because the estimates are uncertain and could be easily overturned.

AUTHORS' CONCLUSIONS

We found sufficient evidence across a large evidence base (59 studies, over 5000 participants) that CBT has small or very small beneficial effects for reducing pain, disability, and distress in chronic pain, but we found insufficient evidence to assess AEs. Quality of evidence for CBT was mostly moderate, except for disability, which we rated as low quality. Further trials may provide more precise estimates of treatment effects, but to inform improvements, research should explore sources of variation in treatment effects. Evidence from trials of BT and ACT was of moderate to very low quality, so we are very uncertain about benefits or lack of benefits of these treatments for adults with chronic pain; other treatments were not analysed. These conclusions are similar to our 2012 review, apart from the separate analysis of ACT.

Mindfulness-Based Stress Reduction in the Management of Chronic Pain and Its Comorbid Depression

CONTEXT

Chronic pain (CP) is a common and serious medical condition, with an estimated 100 million people affected in the United States. In the 1990s, opioids were increasingly prescribed to manage chronic pain, and this practice contributed to the opioid epidemic of the 21st century. To combat this epidemic, multidisciplinary approaches to chronic pain management are being researched and implemented.

OBJECTIVE

To evaluate the clinical effectiveness of an 8-week mindfulness-based stress reduction (MBSR) course implemented in a semi-rural population with chronic pain.

METHODS

Participants were recruited from a community-based teaching hospital in Corvallis, Oregon, for a pre-post study. Participants aged 34 to 77 years who reported having chronic pain lasting for at least 1 year before enrollment were included. Participants took an 8-week group MBSR course in 2.5-hour weekly sessions taught by an experienced MBSR instructor. Techniques were self-practiced between sessions with a goal of 30 minutes per day, 6 days per week. Pre- and postsurvey measurements of pain, depression, and functional capacity were taken via online surveys using the patient health questionnaire (PHQ-9), the Pain Catastrophizing Scale (PCS), and a shortened version of the Modified Oswestry Disability Index (MO). Participants were asked about their satisfaction with the program content, instructor, timing, and location.

RESULTS

Twenty-eight participants were included in the study. Paired t tests found significant improvements in PHQ-9, PCS, and MO percent scores from before to after the course. PHQ-9 scores decreased by a mean of 3.7 points (95% CI, -5.5, -1.8), PCS scores decreased by a mean of 4.6 points (95% CI: -7.2, -2.0), and MO percent score decreased by a mean of 9.4% (95% CI: -14.2%, -4.6%). Results showed an overall downward shift in the distribution of depression, disability, and pain scores after the course.

CONCLUSIONS

MBSR classes were found to benefit participants with chronic pain and depression in this setting, fostering significant improvement in participant perceptions of pain, mood, and functional capacity.

Attention to breath sensations does not engage endogenous opioids to reduce pain

The endogenous opioidergic system is critically involved in the cognitive modulation of pain. Slow-breathing-based techniques are widely used nonpharmacological approaches to reduce pain. Yet, the active mechanisms of actions supporting these practices are poorly characterized. Growing evidence suggest that mindfulness-meditation, a slow-breathing technique practiced by nonreactively attending to breathing sensations, engages multiple unique neural mechanisms that bypass opioidergically mediated descending pathways to reduce pain. However, it is unknown whether endogenous opioids contribute to pain reductions produced by slow breathing. The present double-blind, placebo-controlled crossover study examined behavioral pain responses during mindfulness-meditation (n = 19), sham-mindfulness meditation (n = 20), and slow-paced breathing (n = 20) in response to noxious heat (49°C) and intravenous administration (0.15 mg/kg bolus + 0.1 mg/kg/hour maintenance infusion) of the opioid antagonist, naloxone, and placebo saline. Mindfulness significantly reduced pain unpleasantness ratings across both infusion sessions when compared to rest, but not pain intensity. Slow-paced breathing significantly reduced pain intensity and unpleasantness ratings during naloxone but not saline infusion. Pain reductions produced by mindfulness-meditation and slow-paced breathing were insensitive to naloxone when compared to saline administration. By contrast, sham-mindfulness meditation produced pain unpleasantness reductions during saline infusion but this effect was reversed by opioidergic antagonism. Sham-mindfulness did not lower pain intensity ratings. Self-reported "focusing on the breath" was identified as the operational feature particularly unique to the mindfulness-meditation and slow paced-breathing, but not sham-mindfulness meditation. Across all individuals, attending to the breath was associated with naloxone insensitive pain-relief. These findings provide evidence that slow breathing combined with attention to breath reduces pain independent of endogenous opioids.

Enhanced mindfulness-based stress reduction in episodic migraine: a randomized clinical trial with magnetic resonance imaging outcomes

We aimed to evaluate the efficacy of an enhanced mindfulness-based stress reduction (MBSR+) vs stress management for headache (SMH). We performed a randomized, assessor-blind, clinical trial of 98 adults with episodic migraine recruited at a single academic center comparing MBSR+ (n = 50) with SMH (n = 48). MBSR+ and SMH were delivered weekly by group for 8 weeks, then biweekly for another 8 weeks. The primary clinical outcome was reduction in headache days from baseline to 20 weeks. Magnetic resonance imaging (MRI) outcomes included activity of left dorsolateral prefrontal cortex (DLPFC) and cognitive task network during cognitive challenge, resting state connectivity of right dorsal anterior insula to DLPFC and cognitive task network, and gray matter volume of DLPFC, dorsal anterior insula, and anterior midcingulate. Secondary outcomes were headache-related disability, pain severity, response to treatment, migraine days, and MRI whole-brain analyses. Reduction in headache days from baseline to 20 weeks was greater for MBSR+ (7.8 [95% CI, 6.9-8.8] to 4.6 [95% CI, 3.7-5.6]) than for SMH (7.7 [95% CI 6.7-8.7] to 6.0 [95% CI, 4.9-7.0]) (P = 0.04). Fifty-two percent of the MBSR+ group showed a response to treatment (50% reduction in headache days) compared with 23% in the SMH group (P = 0.004). Reduction in headache-related disability was greater for MBSR+ (59.6 [95% CI, 57.9-61.3] to 54.6 [95% CI, 52.9-56.4]) than SMH (59.6 [95% CI, 57.7-61.5] to 57.5 [95% CI, 55.5-59.4]) (P = 0.02). There were no differences in clinical outcomes at 52 weeks or MRI outcomes at 20 weeks, although changes related to cognitive networks with MBSR+ were observed. Enhanced mindfulness-based stress reduction is an effective treatment option for episodic migraine.

What Works in Mindfulness Interventions for Medically Unexplained Symptoms? A Systematic Review

Background/Purpose: Mindfulness-based interventions (MBIs) have been used in medically unexplained symptoms (MUS). This systematic review describes the literature investigating the general effect of MBIs on MUS and identifies the effects of specific MBIs on specific MUS conditions. Methods: The Preferred Reporting Items for Systematic Reviews and Meta-Analysis Guidelines (PRISMA) and the modified Oxford Quality Scoring System (Jadad score) were applied to the review, yielding an initial 1,556 articles. The search engines included PubMed, ScienceDirect, Web of Science, Scopus, EMBASE, and PsychINFO using the search terms: mindfulness, or mediations, or mindful or MBCT or MBSR and medically unexplained symptoms or MUS or Fibromyalgia or FMS. A total of 24 articles were included in the final systematic review. Results/Conclusions: MBIs showed large effects on: symptom severity (d  = 0.82), pain intensity (d  = 0.79), depression (d  = 0.62), and anxiety (d  = 0.67). A manualized MBI that applies the four fundamental elements present in all types of interventions were critical to efficacy. These elements were psycho-education sessions specific to better understand the medical symptoms, the practice of awareness, the nonjudgmental observance of the experience in the moment, and the compassion to ones’ self. The effectiveness of different mindfulness interventions necessitates giving attention to improve the gaps that were identified related to home-based practice monitoring, competency training of mindfulness teachers, and sound psychometric properties to measure the mindfulness practice.

Self-Administered Skills-Based Virtual Reality Intervention for Chronic Pain: Randomized Controlled Pilot Study

Background

Patients with chronic pain often have limited access to comprehensive care that includes behavioral pain management strategies. Virtual reality (VR) is an immersive technology and emerging digital behavioral pain therapy with analgesic efficacy for acute pain. We found no scientific literature on skills-based VR behavioral programs for chronic pain populations.

Objective

The primary aim of this study is to evaluate the feasibility of a self-administered VR program that included content and skills informed by evidence-based behavioral treatment for chronic pain. The secondary aim is to determine the preliminary efficacy of the VR program in terms of average pain intensity and pain-related interference with activity, stress, mood, and sleep, and its impact on pain-related cognition and self-efficacy. The tertiary aim was to conduct a randomized controlled trial (RCT) and compare the VR treatment with an audio-only treatment. This comparison isolated the immersive effects of the VR program, thereby informing potential mechanisms of effect.

Methods

We conducted an RCT involving a web-based convenience sample of adults (N=97) aged 18-75 years with self-reported chronic nonmalignant low back pain or fibromyalgia, with an average pain intensity >4 over the past month and chronic pain duration >6 months. Enrolled participants were randomly assigned to 1 of 2 unblinded treatments: (1) VR: a 21-day, skills-based VR program for chronic pain; and (2) audio: an audio-only version of the 21-day VR program. The analytic data set included participants who completed at least 1 of 8 surveys administered during the intervention period: VR (n=39) and audio (n=35).

Results

The VR and audio groups launched a total of 1067 and 1048 sessions, respectively. The majority of VR participants (n=19/25, 76%) reported no nausea or motion sickness. High satisfaction ratings were reported for VR (n=24/29, 83%) and audio (n=26/33, 72%). For VR efficacy, symptom improvement over time was found for each pain variable (all P<.001), with results strengthening after 2 weeks. Importantly, significant time×group effects were found in favor of the VR group for average pain intensity (P=.04), pain-related inference with activity (P=.005), sleep (P<.001), mood (P<.001), and stress (P=.003). For pain catastrophizing and pain self-efficacy, we found a significant declining trend for both treatment groups.

Conclusions

High engagement and satisfaction combined with low levels of adverse effects support the feasibility and acceptability of at-home skills-based VR for chronic pain. A significant reduction in pain outcomes over the course of the 21-day treatment both within the VR group and compared with an audio-only version suggests that VR has the potential to provide enhanced treatment and greater improvement across a range of pain outcomes. These findings provide a foundation for future research on VR behavioral interventions for chronic pain.

The Association Between Mindfulness and Postoperative Pain: A Prospective Cohort Study of Gynecologic Oncology Patients Undergoing Minimally Invasive Hysterectomy

STUDY OBJECTIVE

To describe the association between preoperative dispositional mindfulness (the personality trait of being mindful) and postoperative pain in gynecologic oncology patients undergoing minimally invasive hysterectomy.

DESIGN

Prospective cohort study.

SETTING

University-affiliated teaching hospital.

PATIENTS

Gynecologic oncology patients (n = 126) planning minimally invasive hysterectomy.

INTERVENTIONS

Minimally invasive hysterectomy.

MEASUREMENTS AND MAIN RESULTS

Baseline mindfulness was assessed at the preoperative visit using the Five Facet Mindfulness Questionnaire (FFMQ). Postoperative pain and opioid usage were evaluated via chart review and surveys at postoperative visits at 1 to 2 weeks and 4 to 6 weeks. Higher baseline mindfulness was correlated with lower postoperative pain as measured by both the average and highest numeric pain scores during the inpatient stay (r = -.23, p = .020; r = -.21, p = .034). At the initial postoperative visit, pain score was also inversely correlated with preoperative mindfulness score (r = -.26, p = .008). This relationship was not observed at the final postoperative visit (r = -.08, p = .406). Pre-operative mindfulness and opioid usage were also inversely associated, though this relationship did not reach statistical significance (r = -.18, p = .066).

CONCLUSION

Mindfulness was previously shown to be a promising intervention for chronic pain treatment. Our study demonstrates that higher preoperative dispositional mindfulness is associated with more favorable postoperative pain outcomes, including lower pain scores but not lower opioid consumption. This relationship provides an opportunity to target the modifiable personality characteristic of mindfulness, to reduce postoperative pain in patients following gynecologic surgery.

Emerging Clinical Technology: Application of Machine Learning to Chronic Pain Assessments Based on Emotional Body Maps

Depression and anxiety co-occur with chronic pain, and all three are thought to be caused by dysregulation of shared brain systems related to emotional processing associated with body sensations. Understanding the connection between emotional states, pain, and bodily sensations may help understand chronic pain conditions. We developed a mobile platform for measuring pain, emotions, and associated bodily feelings in chronic pain patients in their daily life conditions. Sixty-five chronic back pain patients reported the intensity of their pain, 11 emotional states, and the corresponding body locations. These variables were used to predict pain 2 weeks later. Applying machine learning, we developed two predictive models of future pain, emphasizing interpretability. One model excluded pain-related features as predictors of future pain, and the other included pain-related predictors. The best predictors of future pain were interactive effects of (a) body maps of fatigue with negative affect and (b) positive affect with past pain. Our findings emphasize the contribution of emotions, especially emotional experience felt in the body, to understanding chronic pain above and beyond the mere tracking of pain levels. The results may contribute to the generation of a novel artificial intelligence framework to help in the development of better diagnostic and therapeutic approaches to chronic pain.

Are Opioids Needed to Treat Chronic Low Back Pain? A Review of Treatment Options and Analgesics in Development

The continued prevalence of chronic low back pain (CLBP) is a testament to our lack of understanding of the potential causes, leading to significant treatment challenges. CLBP is the leading cause of years lived with disability and the fifth leading cause of disability-adjusted life-years. No single non-pharmacologic, pharmacologic, or interventional therapy has proven effective as treatment for the majority of patients with CLBP. Although non-pharmacologic therapies are generally helpful, they are often ineffective as monotherapy and many patients lack adequate access to these treatments. Noninvasive treatment measures supported by evidence include physical and chiropractic therapy, yoga, acupuncture, and non-opioid and opioid pharmacologic therapy; data suggest a moderate benefit, at most, for any of these therapies. Until our understanding of the pathophysiology and treatment of CLBP advances, clinicians must continue to utilize rational multimodal treatment protocols. Recent Centers for Disease Control and Prevention guidelines for opioid prescribing recommend that opioids not be utilized as first-line therapy and to limit the doses when possible for fear of bothersome or dangerous adverse effects. In combination with the current opioid crisis, this has caused providers to minimize or eliminate opioid therapy when treating patients with chronic pain, leaving many patients suffering despite optimal nonopioid therapies. Therefore, there remains an unmet need for effective and tolerable opioid receptor agonists for the treatment of CLBP with improved safety properties over legacy opioids. There are several such agents in development, including opioids and other agents with novel mechanisms of action. This review critiques non-pharmacologic and pharmacologic treatment modalities for CLBP and examines the potential of novel opioids and other analgesics that may be a useful addition to the treatment options for patients with chronic pain.

Efficacy and mechanisms of a single-session behavioral medicine class among patients with chronic pain taking prescription opioids: study protocol for a randomized controlled trial

Background

Independent of pain intensity, pain-specific distress is highly predictive of pain treatment needs, including the need for prescription opioids. Given the inherently distressing nature of chronic pain, there is a need to equip individuals with pain education and self-regulatory skills that are shown to improve adaptation and improve their response to medical treatments. Brief, targeted behavioral medicine interventions may efficiently address the key individual factors, improve self-regulation in the context of pain, and reduce the need for opioid therapy. This highlights the critical need for targeted, cost-effective interventions that efficiently address the key psychological factors that can amplify the need for opioids and increased risk for misuse. In this trial, the primary goal is to test the comparative efficacy of a single-session skills-based pain management class to a health education active control group among patients with chronic pain who are taking opioids.

Methods/design

Our study is a randomized, double-blind clinical trial testing the superiority of our 2-h, single-session skills-based pain management class against a 2-h health education class. We will enroll 136 adult patients with mixed-etiology chronic pain who are taking opioid prescription medication and randomize 1:1 to one of the two treatment arms. We hypothesize superiority for the skills-based pain class for pain control, self-regulation of pain-specific distress, and reduced opioid use measured by daily morphine equivalent. Team researchers masked to treatment assignment will assess outcomes up to 12 months post treatment.

Discussion

This study aims to test the utility of a single-session, 2-h skills-based pain management class to improve self-regulation of pain and reduce opioid use. Findings from our project have the potential to shift current research and clinical paradigms by testing a brief and scalable intervention that could reduce the need for opioids and prevent misuse effectively, efficiently, and economically. Further, elucidation of the mechanisms of opioid use can facilitate refinement of more targeted future treatments.

Effects of Mindfulness-Based Stress Reduction and Mindfulness-Based Cognitive Therapy in People With Diabetes: A Systematic Review and Meta-Analysis

PURPOSE

The purpose of this study was to determine the effectiveness of mindfulness-based stress reduction (MBSR) and mindfulness-based cognitive therapy (MBCT) on depression, quality of life (QoL), and glycosylated hemoglobin (HbA1c) in people with diabetes.

DESIGN

A systematic literature review and meta-analysis was conducted.

METHODS

Eight databases (PubMed, Embase, the Cumulative Index to Nursing and Allied Health Literature [CINAHL], Cochrane, PsycINFO, and three Chinese databases) were searched for relevant studies from inception to December 2019. Only randomized controlled trials (RCTs) of MBSR and MBCT interventions for people with type 1 and type 2 diabetes were included.

FINDINGS

Nine studies described in 11 articles were included in the review. Meta-analysis showed a significant effect favoring MBSR and MBCT on depression (standardized mean difference -0.84; 95% confidence interval [CI] -1.16 to -0.51; p < .0001), the mental health composite score of QoL (mean difference [MD] 7.06; 95% CI 5.09 to 9.03; p < .00001), and HbA1c (MD -0.28; 95% CI -0.47 to -0.09; p = .004). However, effects on the physical health composite score of QoL have not been found.

CONCLUSIONS

MBSR and MBCT are beneficial in improving depression, the mental health composite score of QoL, and HbA1c in people with diabetes. More well-designed trials using longer follow-up measurements are needed.

CLINICAL RELEVANCE

MBSR and MBCT could be considered as effective complementary treatment alternatives for people with diabetes.

The OPTIMIZE study: protocol of a pragmatic sequential multiple assessment randomized trial of nonpharmacologic treatment for chronic, nonspecific low back pain

BACKGROUND

Low back pain is a prevalent condition that causes a substantial health burden. Despite intensive and expensive clinical efforts, its prevalence is growing. Nonpharmacologic treatments are effective at improving pain-related outcomes; however, treatment effect sizes are often modest. Physical therapy (PT) and cognitive behavioral therapy (CBT) have the most consistent evidence of effectiveness. Growing evidence also supports mindfulness-based approaches. Discussions with providers and patients highlight the importance of discussing and trying options to find the treatment that works for them and determining what to do when initial treatment is not successful. Herein, we present the protocol for a study that will evaluate evidence-based, protocol-driven treatments using PT, CBT, or mindfulness to examine comparative effectiveness and optimal sequencing for patients with chronic low back pain.

METHODS

The Optimized Multidisciplinary Treatment Programs for Nonspecific Chronic Low Back Pain (OPTIMIZE) Study will be a multisite, comparative effectiveness trial using a sequential multiple assessment randomized trial design enrolling 945 individuals with chronic low back pain. The co-primary outcomes will be disability (measured using the Oswestry Disability Index) and pain intensity (measured using the Numerical Pain Rating Scale). After baseline assessment, participants will be randomly assigned to PT or CBT. At week 10, participants who have not experienced at least 50% improvement in disability will be randomized to cross-over phase-1 treatments (e.g., PT to CBT) or to Mindfulness-Oriented Recovery Enhancement (MORE). Treatment will consist of 8 weekly sessions. Long-term outcome assessments will be performed at weeks 26 and 52.

DISCUSSION

Results of this study may inform referring providers and patients about the most effective nonoperative treatment and/or sequence of nonoperative treatments to treat chronic low back pain.

TRIAL REGISTRATION

This study was prospectively registered on March 1, 2019, with Clinicaltrials.gov under the registration number NCT03859713 (https://clinicaltrials.gov/ct2/show/NCT03859713).

Psychological Therapy for Centralized Pain: An Integrative Assessment and Treatment Model

OBJECTIVE

Chronic pain is a significant health problem that is increasing in prevalence, and advances in treatment are needed.

METHODS

We briefly review the leading evidence-based psychological therapies for chronic pain-cognitive-behavioral and acceptance/mindfulness-based therapies-and examine several limitations and missing perspectives of these approaches. We review six lesser-known interventions that address these limitations, and we describe our integrative model for psychological assessment and treatment of centralized pain. We present a typical patient and describe how we apply this approach, along with challenges to its implementation and possible solutions to these challenges.

RESULTS

Greater pain treatment efficacy may be possible if clinicians: (a) distinguish patients with primarily centralized (i.e., somatoform or nociplastic) pain from those with primarily peripheral (nociceptive, inflammatory, or neuropathic) pain; (b) acknowledge the capacity of the brain not only to modulate pain but also generate as well as attenuate or eliminate centralized pain; (c) consider the powerful role that adverse life experiences and psychological conflicts play in centralized pain; and (d) integrate emotional processing and interpersonal changes into treatment. Our integrative treatment involves delivering a progression of interventions, as needed, to achieve pain reduction: tailored pain neuroscience education, cognitive and mindfulness skills to decrease the pain danger alarm mechanism, behavioral engagement in avoided painful and other feared activities, emotional awareness and expression to reverse emotional avoidance and overcome trauma or psychological conflict, and adaptive communication to decrease interpersonal stress.

CONCLUSIONS

This integrative assessment and treatment model has the potential to substantially reduce and sometimes eliminate centralized pain by changing the cognitive, behavioral, emotional, and interpersonal processes that trigger and maintain centralized pain.

The Impact of Preoperative Mindfulness-Based Stress Reduction on Postoperative Outcomes in Lumbar Spine Degenerative Disease: 3-Month and 12-Month Results of a Pilot Study

BACKGROUND

We previously reported inpatient and 30-day postoperative patient-reported outcomes (PROs) of a controlled, noncrossover pilot study using preoperative mindfulness-based stress reduction (MBSR) training for lumbar spine surgery. Our goal here was to assess 3-month and 12-month postoperative PROs of preoperative MBSR in lumbar spine surgery for degenerative disease.

METHODS

Intervention group participants were prospectively enrolled in a preoperative online MBSR course. A comparison standard care only group was one-to-one matched retrospectively by age, sex, surgery type, and prescription opioid use. Three-month and 12-month postoperative PROs for pain, disability, quality of life, and opioid use were compared within and between groups. Regression models were used to assess whether MBSR use predicted outcomes.

RESULTS

Twenty-four participants were included in each group. At 3 months, follow-up was 87.5% and 95.8% in the comparison and intervention groups, respectively. In the intervention group, mean Patient-Reported Outcomes Measurement Information System-Physical Function (PROMIS-PF) was significantly higher, whereas mean Patient-Reported Outcomes Measurement Information System-Pain Interference (PROMIS-PI) and Oswestry Disability Index were significantly lower. The change from baseline in mean PROMIS-PF and PROMIS-PI was significantly greater than in the comparison group. At 12 months, follow-up was 58.3% and 83.3% in the comparison and intervention groups, respectively. In the intervention group, mean PROMIS-PI was significantly lower and change in mean PROMIS-PI from baseline was significantly greater. MBSR use was a significant predictor of change in PROMIS-PF at 3 months and in PROMIS-PI at 12 months. No adverse events were reported.

CONCLUSIONS

Three-month and 12-month results suggest that preoperative MBSR may have pain control benefits in lumbar spine surgery.

Meta-Analysis of Integrated Therapeutic Methods in Noninvasive Lower Back Pain Therapy (LBP): The Role of Interdisciplinary Functional Diagnostics

Introduction. Lower back pain (LBP) is almost a problem of civilizations. Quite often, it is a consequence of many years of disturbed distribution of tension within the human body caused by local conditions (injuries, hernias, stenoses, spondylolisthesis, cancer, etc.), global factors (postural defects, structural integration disorders, lifestyle, type of activity, etc.), or systemic diseases (connective tissue, inflammation, tumours, abdominal aneurysm, and kidney diseases, including urolithiasis, endometriosis, and prostatitis). Therefore, LBP rehabilitation requires the use of integrated therapeutic methods, combining the competences of interdisciplinary teams, both in the process of diagnosis and treatment. Aim of the Study. Given the above, the authors of the article conducted meta-analysis of the literature in terms of integrated therapeutic methods, indicating the techniques focused on a holistic approach to the patient. The aim of the article is to provide the reader with comprehensive knowledge about treating LBP using noninterventional methods. Material and Methods. An extensive search for the materials was conducted online using PubMed, the Cochrane database, and Embase. The most common noninterventional methods have been described, as well as the most relevantly updated and previously referenced treatment of LBP. The authors also proposed noninvasive (measurable) diagnostic procedures for the functional assessment of the musculoskeletal system, including initial, systematic, and cross-sectional control. All figures and images have been prepared by the authors and are their property.

Results

This review article goes beyond combining a detailed description of each procedure with full references, as well as a comprehensive discussion of this very complex and troublesome problem.

Conclusions

Lower back pain is a serious health problem, and this review article will help educate physicians and physiotherapists dealing with LBP in the options of evidence-based treatment. Ultimately, the article introduces and postulates the need to systematize therapeutic procedures in LBP therapy, with a long-term perspective.

Pilot study of a basic individualized cognitive behavioral therapy program for chronic pain in Japan

Background

Chronic pain is a major health problem, and cognitive behavioral therapy (CBT) is its recommended treatment; however, efforts to develop CBT programs for chronic pain and assess their feasibility are remarkably delayed in Asia. Therefore, we conducted this pilot study to develop a basic individualized CBT for chronic pain (CBT-CP) and assessed its feasibility for use in Japan.

Methods

Our study was an open-labeled before–after trial without a control group conducted cooperatively in five Japanese tertiary care hospitals. Of 24 outpatients, 15, age 20–80, who experienced chronic pain for at least three months were eligible. They underwent an eight-session CBT-CP consisting of relaxation via a breathing method and progressive muscle relaxation, behavioral modification via activity pacing, and cognitive modification via cognitive reconstruction. The EuroQol five-dimensional questionnaire five level (EQ5D-5 L) assessment as the primary outcome and quality of life (QOL), pain severity, disability, catastrophizing, self-efficacy, and depressive symptoms as secondary outcomes were measured using self-administered questionnaires at baseline, post-treatment, and 3-month follow-up. Intention-to-treat analyses were conducted.

Results

Effect size for EQ5D-5 L score was medium from baseline to post-treatment (Hedge’s g = − 0.72, 90% confidence interval = − 1.38 to − 0.05) and up to the 3-month follow-up (g = − 0.60, CI = − 1.22 to 0.02). Effect sizes for mental and role/social QOL, disability, catastrophizing, self-efficacy, and depressive symptoms were medium to large, although those for pain severity and physical QOL were small. The dropout rate was acceptably low at 14%. No severe adverse events occurred.

Conclusion

The findings suggest that CBT-CP warrants a randomized controlled trial in Japan.

The chronic pain skills study: Protocol for a randomized controlled trial comparing hypnosis, mindfulness meditation and pain education in Veterans

OBJECTIVES

To describe the protocol of a randomized controlled trial to evaluate the effectiveness and mechanisms of three behavioral interventions.

METHODS

Participants will include up to 343 Veterans with chronic pain due to a broad range of etiologies, randomly assigned to one of three 8-week manualized in-person group treatments: (1) Hypnosis (HYP), (2) Mindfulness Meditation (MM), or (3) Education Control (EDU).

PROJECTED OUTCOMES

The primary aim of the study is to compare the effectiveness of HYP and MM to EDU on average pain intensity measured pre- and post-treatment. Additional study aims will explore the effectiveness of HYP and MM compared to EDU on secondary outcomes (i.e., pain interference, sleep, depression, anxiety and PTSD), and the maintenance of effects at 3- and 6-months post-treatment. Participants will have electroencephalogram (EEG) assessments at pre- and post-treatment to determine if the power of specific brain oscillations moderate the effectiveness of HYP and MM (Study Aim 2) and examine brain oscillations as possible mediators of treatment effects (exploratory aim). Additional planned exploratory analyses will be performed to identify possible treatment mediators (i.e., pain acceptance, catastrophizing, mindfulness) and moderators (e.g., hypnotizability, treatment expectations, pain type, cognitive function).

SETTING

The study treatments will be administered at a large Veterans Affairs Medical Center in the northwest United States. The treatments will be integrated within clinical infrastructure and delivered by licensed and credentialed health care professionals.

Pain Education With Therapeutic Exercise in Chronic Nonspecific Low Back Pain Rehabilitation: A Critically Appraised Topic

Clinical Scenario: Low back pain is widely prevalent in the general population as well as in athletes. Therapeutic exercise is a low-risk and effective treatment option for chronic pain that can be utilized by all rehabilitation clinicians. However, therapeutic exercise alone does not address the psychosocial aspects that are associated with chronic low back pain. Pain education is the umbrella term utilized to encompass any type of education to the patient about their chronic pain. Therapeutic exercise in combination with pain education may allow for more well-rounded and effective treatment for patients with chronic nonspecific low back pain (NS-LBP). Clinical Question: Does pain education combined with therapeutic exercise, compared with therapeutic exercise alone, improve patient pain in adults with chronic NS-LBP over a 2- to 3-month treatment period? Summary of Key Findings: A thorough literature review yielded 8 studies potentially relevant to the clinical question, and 3 studies that met the inclusion criteria were included. The 3 studies included reports that exercise therapy reduced symptoms. Two of the 3 included studies support the claim that exercise therapy reduces the symptoms of chronic NS-LBP when combined with pain education, whereas one study found no difference between pain education with therapeutic exercise. Clinical Bottom Line: There is moderate evidence to support the use of pain education along with therapeutic exercise when attempting to reduce symptoms of pain and disability in patients with chronic NS-LBP. Educational interventions should be created to educate patients about the foundation of pain, and pain education should be implemented as a part of the clinician's strategy for the rehabilitation of patients with chronic NS-LBP. Strength of Recommendation: Grade B evidence exists to support the use of patient education with therapeutic exercise for decreasing pain in patients with chronic NS-LBP.

Theoretical Model of Mindful Coping Power: Optimizing a Cognitive Behavioral Program for High-Risk Children and Their Parents by Integrating Mindfulness

This paper describes a theoretical model of Mindful Coping Power, a preventive intervention targeting high-risk children and their parents. Mindful Coping Power integrated mindfulness into Coping Power, an evidence-based cognitive behavioral intervention. Reactive aggression is emotionally driven, impulsive, and often referred to as being "hot-blooded." It has been resistant to change, given the high level of emotional arousal and impulsive angry outbursts. Our premise is that mindfulness impacts the mechanisms of reactive aggression-attentional, cognitive, behavioral, and emotional dysregulation. Also in the model are parents who exhibit emotionally charged interactions with their child. Mindful parenting focuses on parents' own emotional self-regulation and being fully present with their child. Our model sets the stage for incorporating mindfulness into existing interventions, thereby optimizing programs and maximizing effects.

Personality and nonjudging make you happier: Contribution of the Five-Factor Model, mindfulness facets and a mindfulness intervention to subjective well-being

Mindful individuals are able to acknowledge mind wandering and live in the present moment in a nonjudgmental way. Previous studies have found that both mind wandering and mindfulness are associated with subjective well-being. However, the main predictor of happiness is personality; more specifically, happier people are emotionally stable and extraverted. The present study aimed to explore the contribution of the five factors of personality, dispositional mindfulness facets and a mindfulness intervention to happiness. A sample of 372 university students was assessed with the NEO-Five Factor Inventory, and another sample of 217 community adults answered the Big Five Personality Trait Short Questionnaire. Both samples, 589 participants in all, completed the Five Facet Mindfulness Questionnaire and the Subjective Happiness Scale. Furthermore, 55 participants from the general population sample took a 6-week training course in meditation and developing mindfulness. The regression analyses showed that emotional stability and extraversion traits were the strongest predictors of subjective well-being. Nonetheless, the nonjudging facet, which is nonevaluative/acceptance awareness of thoughts and feelings, still remained a significant predictor of happiness when personality was accounted for. Finally, mindfulness training did not increase subjective well-being. Being nonjudgmental of one's inner thoughts, feelings and sensations contributes to happiness even when personality is taken into account. Accordingly, it seems reasonable that mindfulness training that intends to improve subjective well-being should focus on noticing thoughts without judging them.

Hypnotherapy or medications: a randomized noninferiority trial in urgency urinary incontinent women

BACKGROUND

Urgency urinary incontinence afflicts many adults, and most commonly affects women. Medications, a standard treatment, may be poorly tolerated, with poor adherence. This warrants investigation of alternative interventions. Mind-body therapies such as hypnotherapy may offer additional treatment options for individuals with urgency urinary incontinence.

OBJECTIVE

To evaluate hypnotherapy's efficacy compared to medications in treating women with urgency urinary incontinence.

MATERIALS AND METHODS

This investigator-masked, noninferiority trial compared hypnotherapy to medications at an academic center in the southwestern United States, and randomized women with non-neurogenic urgency urinary incontinence to weekly hypnotherapy sessions for 2 months (and continued self-hypnosis thereafter) or to medication and weekly counseling for 2 months (and medication alone thereafter). The primary outcome was the between-group comparison of percent change in urgency incontinence on a 3-day bladder diary at 2 months. Important secondary outcomes were between-group comparisons of percent change in urgency incontinence at 6 and 12 months. Outcomes were analyzed based on noninferiority margins of 5% for between group differences (P < 0.025) (that is, for between group difference in percentage change in urgency incontinence, if the lower bound of the 95% confidence interval was greater than -5%, noninferiority would be proved).

RESULTS

A total of 152 women were randomized to treatment between April 2013 and October 2016. Of these women, 142 (70 hypnotherapy, 72 medications) had 3-day diary information at 2 months and were included in the primary outcome analysis. Secondary outcomes were analyzed for women with diary data at the 6-month and then 12-month time points (138 women [67 hypnotherapy, 71 medications] at 6 months, 140 women [69 hypnotherapy, 71 medications] at 12 months. There were no differences between groups' urgency incontinence episodes at baseline: median (quartile 1, quartile 3) for hypnotherapy was 8 (4, 14) and medication was 7 (4, 11) (P = .165). For the primary outcome, although both interventions showed improvement, hypnotherapy did not prove noninferior to medication at 2 months. Hypnotherapy's median percent improvement was 73.0% (95% confidence interval, 60.0-88˖9%), whereas medication's improvement was 88.6% (95% confidence interval, 78.6-100.0%). The median difference in percent change between groups was 0% (95% confidence interval, -16.7% to 0.0%); because the lower margin of the confidence interval did not meet the predetermined noninferiority margin of greater than -5%, hypnotherapy did not prove noninferior to medication. In contrast, hypnotherapy was noninferior to medication for the secondary outcomes at 6 months (hypnotherapy, 85.7% improvement, 95% confidence interval, 75.0-100%; medications, 83.3% improvement, 95% confidence interval, 64.7-100%; median difference in percent change between groups of 0%, 95% confidence interval, 0.0-6.7%) and 12 months (hypnotherapy, 85.7% improvement, 95% confidence interval, 66.7-94.4%; medications, 80% improvement, 95% confidence interval, 54.5-100%; median difference in percent change between groups of 0%, 95% confidence interval, -4.2% to -9.5%).

CONCLUSION

Both hypnotherapy and medications were associated with substantially improved urgency urinary incontinence at all follow-up. The study did not prove the noninferiority of hypnotherapy compared to medications at 2 months, the study's primary outcome. Hypnotherapy proved noninferior to medications at longer-term follow-up of 6 and 12 months. Hypnotherapy is a promising, alternative treatment for women with UUI.

Body-Centered Interventions for Psychopathological Conditions: A Review

World-wide, billions of dollars are spent each year on body-centered interventions to alleviate both physical and psychological pathologies. Given the high demand and increasing popularity of body-centered interventions, there is need for a systematic organization of empirical evidence associated with body-centered therapies. This article reviews the psychological effects of body-centered interventions on emotional well-being, including both self and other-administered (receptive) therapies. Theory behind body-centered interventions rely upon the bidirectional communication pathway between the brain and body. We investigated the bidirectional communication pathway between the brain and body by evaluating evidence across multiple body-centered therapies. The research reviewed includes studies that investigate effects of massage therapy, reflexology, acupuncture, functional relaxation, emotional freedom technique, Rolfing, yoga, tai-chi, and dance/movement therapy on psychological conditions across the lifespan. Results demonstrated that overall, massage therapy, tai-chi, dance/movement therapy, functional relaxation, reflexology, acupuncture and emotional freedom technique seem to alleviate stress, depression, anxiety, bipolar disorder and facilitate pain reduction. Of these, the most robust evidence available was for massage therapy, indicating it is an effective intervention for numerous age groups and populations. Rolfing and reflexology had the least amount of support, with few studies available that had small sample sizes. Although these conclusions are limited by scarcity of high-quality empirical data and contradictory findings, available evidence indicates that body-centered interventions can be effective in reducing psychopathology and supports the proposed mechanism of the bidirectional pathway between the brain and body: the body holds the potential to influence the mind. Integrating body-centered therapies in both clinical settings and as self-care could lead to better outcomes. Lastly, we propose the first taxonomy of body-centered interventions and empirical evidence of their effectiveness for clinicians and researchers.

Pain management for patients with chronic kidney disease in the primary care setting

Pain is routinely reported in patients with chronic kidney disease. Pain is often multifaceted, making the treatment of this complex patient population even more challenging. Understanding pain types as well as treatment options for this patient population is an important skillset for the primary care provider.

Try-It-On: Preparing family nurse practitioners to use holistic integrative interventions to reduce opioid prescriptions in chronic pain management

In the United States, more than 130 people die each day from an opioid overdose. Nonopioid chronic pain management options are necessary in primary care. This educational innovation describes a new curriculum to teach future family nurse practitioner (FNP) prescribers holistic integrative interventions to decrease overprescribing of opioids for chronic pain management. The Modeling and Role Modeling theory and Kirkpatrick Evaluation Model guided the development and implementation of the curriculum innovation using a Try-It-On teaching-learning strategy, which focuses on immersion experience. The focus was to teach students to communicate effectively with patients in an effort to increase patient awareness of the pathophysiology of pain, risks of opioid use, and holistic integrative pain management options. Students learned to manage chronic pain within a holistic focus through immersion within integrative modalities, such as yoga, meditation, mindfulness, and guided imagery. Pre and post participation evaluations documented students' increased comfort level managing patients with chronic pain. Students reported they were much more likely to prescribe holistic integrative modalities after completing the Try-It-On learning modules. Holistic integrative interventions are a viable treatment option and/or adjunct treatment for chronic pain management. In conclusion, using the Try-It-On, teaching-learning strategy provided FNP students with the tools needed to prescribe nonopioid holistic integrative interventions to manage chronic pain.
