Impact of Medical Cannabis on Recovery from Playing-Related Musculoskeletal Disorders in Musicians: An Observational Cohort Study.

Playing-related musculoskeletal disorders (PRMDs) are musculoskeletal symptoms that interfere with the ability to play at the level a musician is accustomed to. Musicians have an 84% lifetime prevalence of PRMD. Many types of analgesia are inappropriate for this population due to their risks, but cannabidiol (CBD) has been shown to have anti-inflammatory properties and can reduce the perception of pain. Medical cannabis has also been shown to be safer than other analgesia in terms of serious adverse events. This study explores the impact of medical cannabis for PRMD on perceptions of pain and mental health outcomes. Participants (n = 204) completed questionnaires at baseline and six months: the Musculoskeletal Pain Intensity and Interference Questionnaire for Musicians (MPIIQM) and Depression, Anxiety and Stress Scale (DASS-21). Participants self-selected their group: non-cannabis users (n = 42), new medical cannabis users (n = 61), and long-term medical cannabis users (n = 101). Data were analyzed using paired t-tests for within-group and ANOVA for between-group differences. At six months, there was no difference (p = 0.579) in cannabidiol dose between new (24.87 ± 12.86 mg) and long-term users (21.48 ± 12.50 mg). There was a difference in tetrahydrocannabinol (THC) dose (p = 0.003) between new (3.74 ± 4.22 mg) and long-term users (4.41 ± 5.18 mg). At six months, new cannabis users had a significant reduction in pain intensity as measured by The Musculoskeletal Pain Intensity and Interference Questionnaire for Musicians (MPIIQM40) (p = 0.002). Non-users (p = 0.035), new users (p = 0.002), and long-term cannabis users (p = 0.009) all had significant reductions in pain interference (MPIIQM50) at six months. At six months, non-cannabis (p = 0.022) and long-term cannabis users (p = 0.001) had an improvement in DASS-21. The change in pain intensity was the only difference between groups, F(2, 201) = 3.845, p = 0.023. This difference was between long-term (0.83 ± 0.79) and new users (-2.61 ± 7.15). No serious adverse events occurred, and a minority experienced tiredness, cough, and dry mouth. This practice-based evidence demonstrated that the multidimensional approach to care provided by the Musicians' Clinics of Canada benefited all groups at six months. Medical cannabis significantly reduced pain intensity in new users of medical cannabis with PRMD, and all groups saw improvements in pain interference. In keeping with prior studies, medical cannabis seems to be effective at reducing perceptions of pain, including for PRMD. CBD/THC dosing was within guideline recommendations, and no patients experienced any serious adverse events. Limitations include multiple factors impacting patients' decisions to opt in or out of medical cannabis. These include cost, comorbidities, and disease chronicity. In conclusion, medical cannabis reduces pain intensity in new users, and when combined with a multidimensional approach to care, patients with PRMD can see improvements in pain as well as mental wellbeing.

Study protocol for the Treating Opioid Patients' Pain and Sadness (TOPPS) study — A randomized control trial to lower depression and chronic pain interference, and increase care retention among persons receiving buprenorphine

BackgroundPersons receiving prescription buprenorphine for opioid use disorder experience high rates of comorbid conditions such as chronic pain and depression, which present barriers to buprenorphine care retention. This paper describes the protocol of the TOPPS (Treating Opioid Patients' Pain and Sadness) study, which compares a values-based, behavioral activation intervention with a health education contact-control condition, with the aim of decreasing chronic pain and depression, and increasing buprenorphine care retention for persons with opioid use disorder. MethodsThis randomized controlled trial (RCT) enrolls and randomizes up to 250 participants currently being treated with buprenorphine to receive three months of either TOPPS, a six-session phone-based behavioral intervention, or a health education (HE) control condition. We compare the TOPPS intervention to HE on the following outcomes: 1) pain interference and pain severity over the 3-month treatment phrase; 2) depressive symptoms over the 3-month treatment phase; and 3) sustained improvements in pain interference, depressive symptoms, and buprenorphine treatment retention over the 12-month study period. We also examine mechanisms by which the intervention may reduce pain interference. DiscussionThis RCT explores a novel intervention to address chronic pain and depression for individuals receiving buprenorphine in office-based settings. TOPPS may lead to improved pain, depression, and substance use outcomes, and can utilize providers available within buprenorphine programs, broadening the disseminability of this intervention and heightening its public health impact.

Collaborative Care for Chronic Pain After Traumatic Brain Injury

Chronic pain after traumatic brain injury (TBI) is prevalent and associated with poor outcomes. By providing multidisciplinary care through expert consultation, a collaborative care (CC) treatment approach may reduce pain interference. To compare CC with usual care (UC) in decreasing pain interference. This randomized clinical trial was conducted from July 2018 through April 2021 at 2 hospital-based academic rehabilitation medicine clinics in Seattle, Washington. Participants included adults with mild-to-severe TBI (at least 6 months before enrollment) and chronic pain. Data analysis was performed from March 30, 2022, to August 30, 2023. The CC intervention (called TBI Care) included up to 12 in-person or telephone visits over 16 weeks with a care manager (CM) who provided person-centered cognitive behavioral treatment. The CM met weekly with members of the expert team to review participants and discuss recommendations to optimize treatment. The primary outcome was pain interference on the Brief Pain Inventory at treatment conclusion (4 months after randomization). Secondary outcomes included pain interference at 8 months; pain severity; symptoms of depression, anxiety, and sleep disturbance; pain-related emergency department visits; community participation; and participant satisfaction. Linear mixed-effects regression was used for analysis. A total of 1379 individuals were screened for eligibility, and 158 were randomized (79 to CC and 79 to UC). The participants were mostly women (92 participants [58%]) with a mean (SD) age of 46.8 (13.2) years and a mean (SD) of 15.3 (3.0) years of education. TBI occurred a mean (SD) of 4.0 (5.9) years (median [IQR], 1.9 [0.8-4.5] years) before enrollment. All TBI severities were included, and of 149 participants for whom TBI severity was known, the majority (97 participants [65%]) had mild TBI. In the CC group, 71 participants (90%) completed at least 11 sessions, and, at 4 months, this group had significantly lower pain interference scores compared with the UC group (mean [SD], 3.46 [2.17] vs 5.03 [2.28]). This difference was maintained at 8 months after randomization, with mean (SD) TBI care pain interference scores of 3.61 (2.22) for CC vs 4.68 (2.51) for UC. At 4 months, there was significantly lower pain severity in the CC group vs UC group (mean [SD] score, 3.63 [1.95] vs 4.90 [1.96]), as well as symptoms of depression (mean [SD] score, 8.07 [5.34] vs 11.31 [6.37]) and anxiety (mean [SD], 6.20 [5.17] vs 9.58 [6.00]). Satisfaction with pain treatment (mean [SD] score, 2.99 [1.23] vs 2.52 [1.25]), clinical care (mean [SD] score, 3.28 [1.00] vs 2.84 [1.26]), and overall health care (mean [SD] score, 3.25 [0.88] vs 2.82 [1.00]) were significantly higher in the CC group vs the UC group; global impression of change was significantly lower in the CC group vs the UC group (mean [SD] score, 2.74 [1.02] vs 3.47 [1.26]) (lower scores denote a better impression of change). In this randomized clinical trial of CC compared with UC for patients with TBI, CC was effective at reducing pain interference and was sustained at 8-month follow-up. Further research is needed to examine the implementation and cost-effectiveness of CC for TBI in other health care settings. ClinicalTrials.gov Identifier: NCT03523923.

Translating an Intervention to Address Chronic Pain among Home Care Workers: The COMPASS-NP Pilot.

To pilot test the COMmunity of Practice And Safety Support for Navigating Pain (COMPASS-NP) intervention for home care workers experiencing chronic pain. Home care workers with chronic pain participated (n = 19; 2 groups) in a 10-week online group program focused on workplace safety and pain self-management. Primary outcomes were changes in pain interference with work and life. Other outcomes related to ergonomics, pain levels, opioid misuse risk, mental health, sleep, and physical activity. The intervention produced a large reduction in pain interference with life ( d = -0.85) and a moderate reduction in pain interference with work time demands ( d = -0.61). Secondary outcomes showed favorable effect sizes, including a substantial increase in the use of ergonomic tools and techniques ( d = 1.47). Findings were strongly encouraging. The effectiveness of COMPASS-NP will be evaluated in a future randomized controlled trial.

Interoceptive bodily awareness in patients seeking pain relief with osteopathic manipulative treatment: an observational cohort pilot study.

Interoceptive bodily awareness (IBA) is one's attentional focus on and relationship with comfortable and uncomfortable (e.g., pain) internal body sensations. Integrating IBA into research on osteopathic manipulative treatment (OMT) is growing, both as an outcome and predictor of treatment outcomes; however, it has yet to be studied in a clinical setting. We aimed to conduct a pilot study to measure IBA, with the Multidimensional Assessment of Interoceptive Awareness (MAIA), in patients seeking OMT for pain, and to test if OMT exposure may be associated with higher IBA as measured by the MAIA. The primary outcome was the change in MAIA scores, and the secondary outcomes were reduction in pain intensity, reduction in pain interference, and increase in participants' perception of change post-OMT. A convenience sample was recruited from individuals presenting for OMT appointments at a College of Osteopathic Medicine OMT teaching clinic. Participants were recruited into our single-arm observational cohort study (n=36), and categorized into one of two groups, OMT-naïve (n=19) or OMT-experienced (n=17), based on prior exposure to OMT. We measured MAIA scores and clinical pain-related outcomes prior to, immediately after, and at 1 and 3weeks after a usual-care OMT session in the clinic. Covariates including experience with mind-body activities, non-OMT body work, and physical and emotional trauma were also collected to explore potential relationships. We utilized t tests to compare MAIA scores and pain outcomes between groups and across time points. Stepwise regression models were utilized to explore potential relationships with covariates. The OMT-experienced group scored higher on theMAIA scales "Not-worrying" (p=0.002) and "Trusting" (p=0.028) at baseline. There were no significant changes in the MAIA scores before and after the single OMT session. Analysis of secondary outcomes revealed that all pain outcomes significantly decreased post-OMT (p<0.05), with the largest relative improvements in the acute pain and OMT-naïve subgroups, with diminishing effects over time. Assessing IBA with MAIA in a clinical OMT setting is feasible. There were significant positive correlations between OMT exposure and two of the eight MAIA scales. Future studies are justified to further explore this relationship.

Brain Function and Pain Interference After Pediatric Intensive Interdisciplinary Pain Treatment.

Intensive interdisciplinary pain treatments (IIPTs) are programs that aim to improve functioning in youth with severe chronic pain. Little is known about how the brain changes after IIPT; however, decreased brain responses to emotional stimuli have been identified previously in pediatric chronic pain relative to healthy controls. We examined whether IIPT increased brain responses to emotional stimuli, and whether this change was associated with a reduction in pain interference. Twenty youths with chronic pain aged 14 to 18 years were scanned using functional magnetic resonance imaging, pre and post-IIPT. During the functional magnetic resonance imaging, patients were presented with emotional stimuli (ie, faces expressing happiness/fear), neutral expressions, and control (ie, scrambled) images. Patients completed a measure of pain interference pre and post-IIPT. Paired t tests were used to examine differences in brain activation in response to emotional versus neutral stimuli, pre to post-IIPT. Data from significant brain clusters were entered into linear mixed models to examine the relationships between brain activation and impairment pre and post-IIPT. Patients demonstrated a decrease in middle frontal gyrus (MFG) activation in response to emotional stimuli (happy + fear) relative to scrambled images, between pre and post-IIPT ( P < 0.05). Lower MFG activation was associated with lower pain interference, pre and post-IIPT ( P < 0.05). Contrary to our hypothesis, IIPT was associated with a reduction in MFG activation to emotional stimuli, and this change was associated with reduced pain interference. The MFG is a highly interconnected brain area involved in both pain chronification and antinociception. With further validation of these results, the MFG may represent an important biomarker for evaluating patient treatment response and target for future pain interventions.

The effects of telehealth-delivered mindfulness meditation, cognitive therapy, and behavioral activation for chronic low back pain: a randomized clinical trial

BackgroundChronic low back pain (CLBP) is a significant problem affecting millions of people worldwide. Three widely implemented psychological techniques used for CLBP management are cognitive therapy (CT), mindfulness meditation (MM), and behavioral activation (BA). This study aimed to evaluate the relative immediate (pre- to post-treatment) and longer term (pre-treatment to 3- and 6-month follow-ups) effects of group, videoconference-delivered CT, BA, and MM for CLBP.MethodsThis is a secondary analysis of a three-arm, randomized clinical trial comparing the effects of three active treatments—CT, BA, and MM—with no inert control condition. Participants were N = 302 adults with CLBP, who were randomized to condition. The primary outcome was pain interference, and other secondary outcomes were also examined. The primary study end-point was post-treatment. Intent-to-treat analyses were undertaken for each time point, with the means of the changes in outcomes compared among the three groups using an analysis of variance (ANOVA). Effect sizes and confidence intervals are also reported.ResultsMedium-to-large effect size reductions in pain interference were found within BA, CT, and MM (ds from − .71 to − 1.00), with gains maintained at both follow-up time points. Effect sizes were generally small to medium for secondary outcomes for all three conditions (ds from − .20 to − .71). No significant between-group differences in means or changes in outcomes were found at any time point, except for change in sleep disturbance from pre- to post-treatment, improving more in BA than MM (d = − .49).ConclusionsThe findings from this trial, one of the largest telehealth trials of psychological treatments to date, critically determined that group, videoconference-delivered CT, BA, and MM are effective for CLBP and can be implemented in clinical practice to improve treatment access. The pattern of results demonstrated similar improvements across treatments and outcome domains, with effect sizes consistent with those observed in prior research testing in-person delivered and multi-modal psychological pain treatments. Thus, internet treatment delivery represents a tool to scale up access to evidence-based chronic pain treatments and to overcome widespread disparities in healthcare.Trial registrationClinicaltrials.gov, NCT03687762.

Add-on Vitamin E in Improving Treatment Outcomes in Diabetic Peripheral Neuropathy: A Prospective Interventional Study

Background: Neuropathy is one of the most common long-standing complications of diabetes, affecting over 50% of the diabetic individuals. Managing DPN and its complications involves comprehensive care and a multidisciplinary approach. Besides pharmacological treatments, botanicals and dietary supplements that have also been found to improve symptoms of DPN without affecting glucose control. The possible role of vitamin E in the management of DPN have been postulated in various studies. The present study thus aimed to prospectively assess whether add-on treatment with vitamin E can improve treatment outcomes in diabetic peripheral neuropathy.Methods: The study included newly diagnosed patients with diabetic peripheral neuropathy for a period of initial two months. Patients were randomly allocated to either standard treatment Group (Group A) or the interventionGroup (Group B). As a part of intervention, patients received vitamin E 400mg once daily in addition to thestandard of care. Efficacy Parameters measured at baseline, 6 months and 12 months included changes in visual analog scoring, mean pain score, brief pain inventory and patient’s global impression of change. Treatment safety, quality of life and treatment adherence was assessed. Data was statistically analysed.Result: The study included a total of 100 patients, 50 patients in each Group. Significantly higher decrease of glycaemic measures was noted for Group B compared to Group A in terms of PPPG and serum creatinine, however, there was comparable change in HbA1c and FPG for both Groups. There was comparable significant reduction in mean VAS scoring at 6 and 12 months for Group B. Considering all the efficacy measures, there was highest reduction for the pain interference in the intervention arm (Group B), in comparison to Group A. (p&lt;0.001). Quality of life measures and mean adherence scoring significantly increased for treatment group B as compared to A at both 6 months and 12 months of study assessments. No major safety concerns were reported during the study period.Conclusion: Our study noted that addition of vitamin E as an added supplementation to the standard of careshowed benefits in terms of patient reported reduced pain interference and pain perception, which also significantly improved overall quality of life in these patients.

464 Remote Cognitive Behavioral Therapy Utilizing an In-home Virtual Reality Toolkit (Vx Therapy TM) Reduces Pain, Anxiety, and Depression in Patients With Chronic Cervical and Lumbar Pain: A Potential Opiate Alternative in Multimodal Pain Management

INTRODUCTION: Virtual reality has reduced acute pain through visual and auditory distraction, as well as altered brain neurobiology. VR attenuates pain-induced brain activity without narcotic-related side effects or dependency. Cognitive behavioral therapy (CBT) has demonstrated improved pain-related anxiety, depression, physical disability, resiliency, and quality of life. CBT access remains a challenge in most care communities. METHODS: 145 patients with chronic neck and back pain (63 cervical, 46 non-radicular lumbar, 36 radicular lumbar) enrolled into a 14 week Vx therapy CBT program with therapist guided utilization of an in-home VR system with 50 modules (education, meditation, distraction, entertainment). Pain and anxiety severity scores were recorded before and immediately after VR use as well as time to pain recurrence. PROMIS measures of daily pain intensity, pain behavior, pain interference, anxiety, and depression were recorded at baseline and after 14 weeks of Vx therapy. RESULTS: PROMIS domains were significantly improved after Vx treatment vs baseline for the entire cohort and each subgroup. VR acutely reduced pain during use on average by 33% (p &lt; 0.05) across all 14 weeks lasting a mean 2.5 hours. VR acutely reduced anxiety during use on average by 46% (p &lt; 0.05) across all 14 weeks lasting a mean 2.7 hours. The effect was similar for all three diagnosis groups. CONCLUSIONS: Remote CBT guided in-home VR toolkit (Vx therapyTM) provided effective multi-hour sustained pain relief in patients with chronic neck and back pain with and without radiculopathy. Significant improvement in overall pain, anxiety, and depression and reduced pain interference was observed. This non-invasive, non-pharmaceutical Vx therapy is an ideal option to improve outcomes in post-opioid pain management.

The efficacy of multimodal physiotherapy and usual care in chronic whiplash-associated disorders with facet-mediated pain undergoing platelet rich plasma (PRP) treatment: a series of single case experimental designs (SCEDs)

Purpose Chronic whiplash-associated disorders (WAD) is a heterogeneous condition with limited effective treatment options available. This study evaluated the efficacy of multimodal physiotherapy and usual care in chronic WAD with facet-mediated pain receiving platelet-rich plasma (PRP) injections to determine if pain interference and confidence completing activities in the presence of neck pain could be improved. Materials and methods A multiple-baseline, single-case experimental design was used to evaluate the 6-week effect of physiotherapy or usual care in two groups of three participants each. Results All six participants demonstrated a significant reduction in pain interference, and three participants showed improved confidence to perform daily activities when in pain. Weighted Tau-U demonstrated a significant reduction of pain interference with large to very large effect sizes (> 0.75) for both interventions in all participants irrespective of treatment allocation with no significant group difference demonstrated. Similar effects were demonstrated for the confidence to perform daily activities with neck pain (ES > 0.46), although this was only evident in three participants (two PT and one UC). Generalisation measures also showed improvements in pain and disability, psychological and quality of life outcomes. No adverse events were reported. Conclusions Both physiotherapy and usual care demonstrated improvements in pain interference and confidence to perform activities of daily living with neck pain in people with chronic WAD following cervical facet joint PRP. Trial Registration The trial was registered with ClinicalTrials.gov (Protocol Number: NCT03949959).

Nonpharmacological Interventions for Chronic Pain in Older Adults: A Systematic Review and Meta-Analysis.

Gate control theory and fear-avoidance model of chronic pain posit that biopsychosocial factors can modulate pain. Nonpharmacological interventions are recommended in managing chronic pain, but little information is available regarding their efficacy in older adults. We examined and compared the efficacy of different nonpharmacological intervention approaches for chronic pain management among older adults via meta-analysis and subgroup analysis. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines (PROSPERO number CRD42020222767), a systematic search was undertaken using MEDLINE, Embase, and PsycINFO up to March 21, 2022. Randomized controlled trials were included, and data were pooled using a random-effects meta-analysis model. Risk of bias was assessed using a quality rating scale for psychological interventions. Twenty-five trials (N = 2,394 participants) were identified. Six types of nonpharmacological interventions were compared with control conditions (sham/attention control and treatment as usual). Nonpharmacological interventions were associated with significant reductions in pain intensity, pain interference, depressive symptoms, catastrophizing beliefs, and improvement in physical performance (standardized mean differences -0.34 to 0.54). Subgroup analyses based on different nonpharmacological approaches revealed the benefits of psychological approaches combined with physical activity. Nonpharmacological interventions, particularly those adopting psychological approaches and physical activity, have a small but statistically significant effect on chronic pain management in older adults. Reduction in pain interference may be related to reduced catastrophizing beliefs, thus providing support for the fear-avoidance model. Further research with adequate power is needed to establish the efficacy and mechanism of various intervention modalities for older adults.

Exercise combined with Acceptance and Commitment Therapy for chronic pain: One-year follow-up from a randomized controlled trial.

Acceptance and Commitment Therapy (ACT) is a type of Cognitive Behavioural Therapy, which has demonstrated positive outcomes in individuals with chronic pain. The purpose of this study was to compare the effect of an 8-week programme combining Exercise with Acceptance and Commitment Therapy (ExACT) with a standalone supervised exercise programme at 1-year follow-up. One hundred and seventy-five people with chronic pain were randomly assigned to ExACT or supervised exercise only. The primary outcome was pain interference measured with the Brief Pain Inventory-Interference Scale. Secondary and treatment process outcomes included pain severity, depression, anxiety, pain catastrophizing, pain self-efficacy, fear avoidance, pain acceptance, committed action, healthcare utilization, patient satisfaction, and global impression of change. Estimates of treatment effects at 1-year follow-up were based on intention-to-treat analyses, implemented using a linear mixed-effects model. Eighty-three participants (47.4%) returned the outcome measures at 1-year follow-up. No significant difference was observed between the groups for the primary outcome, pain interference. There was a statistically significant difference between the groups, in favour of ExACT for pain catastrophizing. Within group improvements that were observed within both groups at earlier timepoints were maintained at 1-year follow-up for many of the secondary and treatment process outcomes. ExACT group participants reported higher levels of satisfaction with treatment and global perceived change. The study results showed no significant difference between the two groups for the primary outcome pain interference at 1-year follow-up. Future research could investigate factors that may predict and optimize outcomes from these types of intervention for people living with chronic pain. Few previous randomized controlled trials investigating ACT for chronic pain have included long-term follow-up. This study found that Exercise combined with ACT was not superior to supervised exercise alone for reducing pain interference at 1-year follow-up. Further research is necessary to identify key processes of therapeutic change and to explore how interventions may be modified to enhance clinical outcomes for people with chronic pain.

Evaluation of intervention components to maximize yoga practice among people with chronic pain taking opioid agonist therapy: A factorial experiment using the multiphase optimization strategy framework

BackgroundChronic pain affects up to half of individuals taking opioid agonist therapy (OAT; i.e., methadone and buprenorphine) for opioid use disorder (OUD), and yoga-based interventions may be useful for decreasing pain-related disability. Whereas more yoga practice (i.e., higher “dosage”) may improve pain-related outcomes, it can be challenging for people with chronic pain taking OAT to attend class regularly and sustain a regular personal yoga practice. Therefore, we plan to optimize a yoga-based intervention (YBI) package in order to support class attendance and personal practice, thus maximizing the yoga dose received. Study designUsing the Multiphase Optimization Strategy (MOST) framework, we will conduct a factorial experiment to examine four intervention components that may be added to a weekly yoga class as part of a YBI. Components include: 1) personal practice videos featuring study yoga teachers, 2) two private sessions with a yoga teacher, 3) daily text messages to inspire personal practice, and 4) monetary incentives for class attendance. The primary outcome will be minutes per week engaged in yoga (including class attendance and personal practice). We plan to enroll 192 adults with chronic pain who are taking OAT for OUD in this 2x2x2x2 factorial experiment. ConclusionResults of the study will guide development of an optimized yoga-based intervention package that maximizes dosage of yoga received. The final treatment package can be tested in a multisite efficacy trial of yoga to reduce pain interference in daily functioning in people with chronic pain who are taking OAT.Trial registration: Pre-registration of the study was completed on ClinicalTrials.gov (identifier: NCT04641221).

Treating a common comorbidity: Pain outcomes following a 3-week cognitive processing therapy-based intensive treatment for posttraumatic stress disorder address.

Posttraumatic stress disorder (PTSD) commonly co-occurs with pain and has been implicated in the maintenance of chronic pain. However, limited research has examined whether intervening for PTSD can hinder or optimize treatment outcomes for co-occurring pain and PTSD. In the present study, we examined changes in pain, PTSD, and depressive symptoms among 125 veterans completing a 3-week cognitive processing therapy (CPT)-based intensive treatment program (ITP) for PTSD. We also explored whether pretreatment pain interference predicted changes in PTSD and depressive symptom severity and whether larger changes in pain interference over the course of treatment were associated with larger changes in PTSD and depressive symptom severity. Linear mixed models revealed that participants' pain interference decreased throughout treatment, d = 0.15, p = .039. Higher levels of pretreatment pain interference were associated with higher PTSD, p = .001, and depressive symptom severity, p = .014, over time. Larger reductions in pain interference corresponded to more improvement in PTSD symptoms, β = -.03; p < .001, but not depressive symptoms. These findings indicate that ITPs for PTSD can reduce pain interferences, albeit to a small degree, and that reductions in pain interference can contribute to reductions in PTSD symptom severity. Future studies should examine which treatment components contribute to larger changes in symptom severity for veterans with co-occurring pain and PTSD.

Meaning-centered pain coping skills training for patients with metastatic cancer: Protocol for a randomized controlled efficacy trial

BackgroundMany patients with advanced cancer describe pain as a debilitating symptom that greatly interferes with daily activities and enjoyment of life. Psychosocial interventions can improve cancer-related pain but rarely address spiritual concerns (e.g., loss of meaning, peace), which can influence the pain experience for those facing life-threatening illness. To address these needs, we systematically developed and pilot tested a novel psychosocial intervention called Meaning-Centered Pain Coping Skills Training (MCPC). In this randomized controlled trial, we aim to determine MCPC's efficacy for reducing pain interference (primary outcome) and improving secondary outcomes. We will also estimate MCPC's cost-effectiveness. Method/DesignPatients (target N = 210) with advanced solid tumor malignancies (Stage IV) and clinically-elevated pain interference will be enrolled and block randomized with equal allocation to MCPC + enhanced usual care or enhanced usual care alone. MCPC's four, videoconferenced, 45–60 min weekly sessions will be individually delivered by trained study therapists. Primary (pain interference) and secondary (pain severity, anxiety and depressive symptoms, pain self-efficacy, social support, spiritual well-being) patient-reported outcomes will be assessed at baseline, and 8-weeks (primary endpoint) and 12-weeks after baseline. ConclusionOur MCPC intervention is the first to systematically address the biopsychosocial-spiritual aspects of pain in patients with advanced cancer. If MCPC demonstrates efficacy, next steps will involve hybrid efficacy-effectiveness and implementation work to broaden access to this brief, manualized, remotely-delivered intervention, with the goal of reducing suffering in patients with life-threatening illness.

Identification and Characterization of Pain Processing Patterns Among Patients with Chronic Primary Pain: A replication.

To develop individual and effective treatment plans for patients with chronic pain, we aimed to replicate Grolimund et al's (2017) empirical categorization of chronic pain patients on a new and larger sample. Moreover, this work aimed to extend previous knowledge by considering various treatment outcomes and exploratorily analyzing which coping skills might be particularly relevant for treatment success in each subtype. Latent class analysis was used to identify homogenous subtypes with different pain processing patterns using the pain processing questionnaire (FESV). By analyzing 602 inpatients with chronic primary pain, we identified three subtypes: (1) severely burdened individuals with low coping skills, (2) mildly burdened individuals with high coping skills, and (3) moderately burdened individuals with moderate coping skills. Pain interference, psychological distress, cognitive and behavioral coping skills improved after treatment in all subtypes. Pain-related mental interference significantly improved only in subtypes (1) and (3). Only individuals of subtype (3) reported significant reductions in pain intensity after treatment. Exploratory regression analysis suggested that of subtype (1), the most promising targets in reducing pain interference and psychological distress post-treatment might be to foster relaxation techniques, counteractive activities, and cognitive restructuring. None of the FESV dimensions significantly predicted treatment outcomes among individuals of subtype (2). Individuals of subtype (3) might benefit the most from experiencing more competence during treatment. Our findings highlight the importance of identifying and characterizing subtypes of chronic primary pain patients and that these subtypes should be considered for individualized and effective treatment.

Associations between patterns of physical activity, pain intensity, and interference among older adults with chronic pain: a secondary analysis of two randomized controlled trials.

Background: Clinical management of chronic pain often includes recommendations to engage in physical activity (PA), though there are little data on the interplay between pain symptoms and key aspects of PA participation (e.g., intensity and bout duration) among older adults. Herein we investigate the longitudinal relationships between changes in PA behavior and changes in pain intensity and interference among low-active older adults with obesity and chronic pain. Methods: Participants (N = 41) were enrolled in two randomized pilot trials wherein they were assigned to an intervention focused on participation in frequent PA across the day, or to a low-contact control. Participants completed the 3-item PROMIS pain intensity scale and 8-item PROMIS pain interference scale before and after the interventions. Participants also wore an ActivPAL accelerometer for 7days before and during the final week of the interventions. Results: A series of linear regression analyses demonstrated that increased time spent stepping at a high-light intensity in very short bouts was associated with increased pain intensity scores. By contrast, increased time spent stepping at a high-light intensity in bouts of 5-20min was associated with reductions in pain intensity and interference scores. Increased time spent stepping at a moderate intensity overall was associated with reduced pain intensity scores, and time spent stepping at a moderate intensity for 10-20min associated with reduced pain interference. Conclusion: These findings suggest older adults with chronic pain may benefit by moving at high-light or moderate intensities in brief bouts of at least 5min in duration.

Emotion-Focused Psychodynamic Interview for People with Chronic Musculoskeletal Pain and Childhood Adversity: A Randomized Controlled Trial

Childhood adversity and emotional conflicts are associated with the presence and severity of chronic musculoskeletal pain (CMP), yet common treatments for CMP do not address such risk factors. We developed a single session, emotion-focused psychodynamic interview, based on Emotional Awareness and Expression Therapy and Intensive Short-term Psychodynamic Therapy, and we tested the interview’s effects on pain-related outcomes and potential psychological mediators in a randomized, controlled trial. Adults (N = 91; ages 21–70, M = 44.64; 87.9% women) reporting CMP and at least 3 adverse childhood experiences completed measures at baseline and 6-week follow-up. Participants were randomized to immediate interview or waitlist control conditions. The 90-minute interview was conducted via videoconference, and the interviewer elicited disclosure of adversities and conflicts, linked these with pain, and encouraged the experience and expression of adaptive emotions. Analyses indicated that conditions did not differ significantly on change in pain severity; however, compared to control, the interview led to a significantly greater reduction in pain interference (P = .016, ηp2 = .05) and a similar trend for anxiety (P = .058, ηp2 = .04). The interview also significantly changed several potential mediators: pain-related anxiety (P = .008, ηp2 = .06), pain controllability (P = .016, ηp2 = .06), and psychological (P < .001, ηp2 = .15) and brain attributions (P = .022, ηp2 = .05) for pain. Participants viewed the interview as very valuable. We conclude that addressing childhood adversities and conflicts in a psychodynamic interview is beneficial for people with CMP. PerspectiveThis study found that, compared to waitlist control, a 90-minute, remotely-administered, emotion-focused, psychodynamic interview improved pain interference, and anxiety among adults with chronic musculoskeletal pain and childhood adversity. Intensive emotional work can be done in a single session to the benefit of patients with chronic musculoskeletal pain.

Reduced symptom burden after implementation of an electronic symptom management program.

12006 Background: The SIMPRO consortium implemented an electronic patient reported outcomes (ePRO) symptom management program as part of routine clinical care for patients (pts) receiving systemic cancer therapy or surgery across six health systems including rural and community cancer centers. To evaluate impact of the Epic-integrated electronic symptom management (eSyM) program on quality of life, pre- and post-implementation surveys were sent to a subset of gastrointestinal, thoracic, and gynecologic medical oncology (MO) and surgical (Surg) patients at all sites. Methods: A survey assessing symptom burden, health literacy, and self-efficacy was administered to separate groups of MO and Surg pts before (Pre-Implementation) and after (Post-Implementation) eSyM deployment. A waiver of documentation of consent was obtained for participation. Questions were derived from validated instruments including PROMIS, a standardized measurement tool for patient-reported symptoms. Surveys were completed 30-90 days after surgery or start of systemic therapy. PROMIS item responses were scored individually then translated into standardized T-scores with a mean of 50 based on an established reference population. Mean T-scores for PROMIS depression, anxiety, fatigue, and pain interference were calculated. Higher T-score correlated with greater symptom burden. Comparison between groups utilized non-parametric Kruskal-Wallis testing. Results: The number of survey responses were 498 MO Pre-Implementation, 518 MO Post-Implementation, 566 Surg Pre-Implementation, and 507 Surg Post-Implementation. MO pts reported significantly lower PROMIS mean T-scores for depression, anxiety, fatigue, and pain interference after eSyM compared to a similar group of MO pts prior to eSyM. Surg pts reported lower T-scores for depression, anxiety, fatigue, and pain interference after eSyM compared to a similar group of Surg pts prior to eSyM, although reduction in pain interference was not statistically significant. Conclusions: eSyM deployment in MO was associated with a significant reduction in patient reported depression, anxiety, fatigue, and pain interference. Surgical pts after eSyM deployment reported significantly lower rates of depression, anxiety, and fatigue. External validation with PROMIS based surveys demonstrated small but meaningful benefits of ePRO symptom monitoring as part of routine clinical care across six diverse health systems.

Efficacy of Videoconference Group Acceptance and Commitment Therapy (ACT) and Behavioral Activation Therapy for Depression (BATD) for Chronic Low Back Pain (CLBP) Plus Comorbid Depressive Symptoms: A Randomized Controlled Trial (IMPACT Study)

This study examined the efficacy of adding a remote, synchronous, group, videoconference-based form of acceptance and commitment therapy (ACT) or behavioral activation therapy for depression (BATD) to treatment-as-usual (TAU) in 234 patients with chronic low back pain (CLBP) plus comorbid depressive symptoms. Participants were randomly assigned to ACT, BATD, or TAU. Compared to TAU, ACT produced a significant reduction in pain interference at posttreatment (d = .64) and at follow-up (d = .73). BATD was only superior to TAU at follow-up (d = .66). A significant reduction in pain catastrophizing was reported by patients assigned to ACT and BATD at posttreatment (d = .45 and d = .59, respectively) and at follow-up (d = .59, in both) compared to TAU. Stress was significantly reduced at posttreatment by ACT in comparison to TAU (d = .69). No significant between-group differences were found in depressive or anxiety symptoms. Clinically relevant number needed to treat (NNT) values for reduction in pain interference were obtained at posttreatment (ACT vs TAU = 4) and at follow-up (ACT vs TAU = 3; BATD vs TAU = 5). In both active therapies, improvements in pain interference at follow-up were significantly related to improvements at posttreatment in psychological flexibility. These findings suggest that new forms of cognitive-behavioral therapy are clinically useful in improving pain interference and pain catastrophizing. Further research on evidence-based change processes is required to understand the therapeutic needs of patients with chronic pain and comorbid conditions. Trial numberNCT04140838. PerspectiveGroup videoconference-based ACT and BATD showed greater efficacy than TAU for reducing pain interference and pain catastrophizing in patients with CLBP plus clinically relevant depression. Psychological flexibility appeared to be the main contributor to treatment effects for both ACT and BATD.
