Pain Education and Virtual Reality Improves Pain, Pain-related Fear of Movement, and Trunk Kinematics in Individuals With Persistent Low Back Pain

OBJECTIVES

To evaluate the effect of combining pain education and virtual reality (VR) exposure therapy using a cognitive-behavioral therapy-informed approach (virtual reality-based cognitive behavioral therapy [VR-CBT]) on pain intensity, fear of movement, and trunk movement in individuals with persistent low back pain.

MATERIALS AND METHODS

Thirty-seven participants were recruited in a single cohort repeated measures study, attending 3 sessions 1 week apart. The VR-CBT intervention included standardized pain education (session 1) and virtual reality-based exposure therapy (VRET; session 2) incorporating gameplay with mixed reality video capture and reflective feedback of performance. Outcome measures (pain intensity, pain-related fear of movement (Tampa Scale of Kinesiophobia), and trunk kinematics during functional movements (maximum amplitude and peak velocity) were collected at baseline (session 1) and 1 week after education (session 2) and VRET (session 3). One-way repeated measures analysis of variances evaluated change in outcomes from baseline to completion. Post hoc contrasts evaluated effect sizes for the education and VR components of VR-CBT.

RESULTS

Thirty-four participants completed all sessions. Significant ( P < 0.001) reductions were observed in mean (SD) pain (baseline 5.9 [1.5]; completion 4.3 [2.1]) and fear of movement (baseline 42.6 [6.4]; completion 34.3 [7.4]). Large effect sizes (Cohen d ) were observed for education (pain intensity: 0.85; fear of movement: 1.28), whereas the addition of VRET demonstrated very small insignificant effect sizes (pain intensity: 0.10; fear of movement: 0.18). Peak trunk velocity, but not amplitude, increased significantly ( P < 0.05) across trunk movement tasks.

CONCLUSION

A VR-CBT intervention improved pain, pain-related fear of movement, and trunk kinematics. Further research should explore increased VR-CBT dosage and mechanisms underlying improvement.

The Role of Virtual Reality and Artificial Intelligence in Cognitive Pain Therapy: A Narrative Review

PURPOSE OF REVIEW

This review investigates the roles of artificial intelligence (AI) and virtual reality (VR) in enhancing cognitive pain therapy for chronic pain management. The work assesses current research, outlines benefits and limitations and examines their potential integration into existing pain management methods.

RECENT FINDINGS

Advances in VR have shown promise in chronic pain management through immersive cognitive therapy exercises, with evidence supporting VR's effectiveness in symptom reduction. AI's personalization of treatment plans and its support for mental health through AI-driven avatars are emerging trends. The integration of AI in hybrid programs indicates a future with real-time adaptive technology tailored to individual needs in chronic pain management. Incorporating AI and VR into chronic pain cognitive therapy represents a promising approach to enhance management by leveraging VR's immersive experiences and AI's personalized tactics, aiming to improve patient engagement and outcomes. Nonetheless, further empirical studies are needed to standardized methodologies, compare these technologies to traditional therapies and fully realize their clinical potential.

Psychotherapy for Ketamine's Enhanced Durability in Chronic Neuropathic Pain: Protocol for a Pilot Randomized Controlled Trial

BACKGROUND

Chronic pain affects approximately 8 million Canadians (~20%), impacting their physical and mental health while burdening the health care system with costs of upwards of US $60 billion a year. Indeed, patients are often trialed on numerous medications over several years without reductions to their symptoms. Therefore, there is an urgent need to identify new therapies for chronic pain to improve patients' quality of life, increase the availability of treatment options, and reduce the burden on the health care system.

OBJECTIVE

The primary objective of this study is to examine the feasibility of a parallel 3-arm pilot randomized controlled trial whereby patients are randomized to either intravenous ketamine alone, cognitive behavioral therapy (CBT) and mindfulness meditation (MM) training (CBT/MM), or the combination of intravenous ketamine and CBT/MM. The secondary outcome is to assess the durability and efficacy of combination intravenous ketamine and CBT/MM for treatment of chronic pain as compared to CBT/MM or intravenous ketamine alone (assessed at week 20 of the study).

METHODS

This is a single-center, 16-week, 3-arm pilot study that will take place at the Chronic Pain Clinic at St. Michael's Hospital, Toronto, Ontario, which receives 1000 referrals per year. Patients will be enrolled in the study for a total of 20 weeks. Participants who are allocated CBT/MM therapy will receive remote weekly psychotherapy from week 1 to week 16, inclusive of health coaching administered through the NexJ Health Inc (NexJ Health) platform. Patients who are allocated ketamine-infusion therapy will receive monthly ketamine infusion treatments on weeks 2, 7, and 12. Patients who are allocated ketamine+CBT/MM will receive weekly psychotherapy from weeks 1 to 16, inclusive, as well as ketamine infusion treatments on weeks 2, 7, and 12. We will be assessing recruitment rates, consent rates, withdrawal rates, adherence, missing data, and adverse events as pilot outcome measures. Secondary clinical outcomes include changes relative to baseline in pain intensity and pain interference.

RESULTS

As of November 1, 2023, the recruitment process has not been initiated. Given the recruitment, consent, and intervention target of 30 participants for this feasibility study, with each patient undergoing monitoring and treatments for a course of 20 weeks, we expect to complete the study by December 2025.

CONCLUSIONS

This study assesses the feasibility of conducting a 3-arm randomized controlled trial to examine the effects of ketamine administration with the concurrent use of CBT/MM in a population with chronic neuropathic pain. The results of this pilot randomized controlled trial will inform the development of a larger-scale randomized controlled trial. Future studies will be aimed at including a sufficiently powered sample that will inform decisions about optimal treatment calibration and treatment effect duration.

Effect of cognitive behavioral therapy on pain, knee function, and psychological status in patients after primary total knee arthroplasty: a systematic review and meta-analysis

OBJECTIVE

The clinical efficacy of cognitive behavioral therapy (CBT) after Total knee arthroplasty (TKA) is still controversial, and the purpose of this meta-analysis was to evaluate the effect of CBT on pain, knee function, and psychological status of patients after TKA.

METHODS

We systematically searched electronic databases such as CNKI, CBM, VIP, PubMed, Cochrane Library, and EMBASE for randomized controlled studies up to February 30, 2023. Screening against inclusion criteria to select valid studies and extract data. The quality of included studies was evaluated by the Cochrane Collaboration risk-of-bias 2 (RoB 2) tool for randomized trials. Statistical analysis of the data from this study was carried out using Stata 15.1 software.

RESULTS

Finally, our meta-analysis incorporated seven randomized controlled studies of high quality, including 608 patients. The findings of the meta-analysis demonstrated a noteworthy decrease in kinesiophobia levels during the early postoperative phase in the CBT group as compared to the usual care group (WMD = -6.35, 95% CI: -7.98 to -4.72, Z = 7.64, P < 0.001). However, no statistically significant difference between the CBT and usual care groups in terms of postoperative pain as well as knee function.

CONCLUSION

CBT may effectively reduce the level of kinesiophobia in the short term after TKA, but did not significantly relieve knee pain or improve knee function.

Patient interest in the development of a center for Ehlers-Danlos syndrome/hypermobility spectrum disorder in the Chicagoland region

BACKGROUND

The Ehlers-Danlos Syndromes (EDS) are a group of connective tissue disorders that are hereditary in nature and characterized by joint hypermobility and tissue fragility. The complex nature of this unique patient population requires multidisciplinary care, but appropriate centers for such care do not exist in large portions of the country. Need for more integrated services has been identified in Chicagoland, or Chicago and its suburbs. In order to explore and begin to address barriers to seeking appropriate care facing EDS patients in this region, we developed an online survey which we circulated through EDS social media groups for Chicagoland patients.

RESULTS

Three hundred and nine unique respondents participated. We found that there exists a strong medical need for and interest in the development of a center in the region, and participants reported that, if made available to them, they would make extensive and regular use of such a facility.

CONCLUSIONS

We conclude that the establishment of a collaborative medical center specializing in the diagnosis and treatment of EDS, Hypermobility Spectrum Disorder, and related disorders in the Chicagoland area would greatly benefit patients by providing comprehensive care, alleviate the burden on overworked healthcare providers, and contribute to the sustainability of medical facilities.

Psycho-Neuroendocrinology in the Rehabilitation Field: Focus on the Complex Interplay between Stress and Pain

Chronic stress and chronic pain share neuro-anatomical, endocrinological, and biological features. However, stress prepares the body for challenging situations or mitigates tissue damage, while pain is an unpleasant sensation due to nociceptive receptor stimulation. When pain is chronic, it might lead to an allostatic overload in the body and brain due to the chronic dysregulation of the physiological systems that are normally involved in adapting to environmental challenges. Managing stress and chronic pain (CP) in neurorehabilitation presents a significant challenge for healthcare professionals and researchers, as there is no definitive and effective solution for these issues. Patients suffering from neurological disorders often complain of CP, which significantly reduces their quality of life. The aim of this narrative review is to examine the correlation between stress and pain and their potential negative impact on the rehabilitation process. Moreover, we described the most relevant interventions used to manage stress and pain in the neurological population. In conclusion, this review sheds light on the connection between chronic stress and chronic pain and their impact on the neurorehabilitation pathway. Our results emphasize the need for tailored rehabilitation protocols to effectively manage pain, improve treatment adherence, and ensure comprehensive patient care.

The ROCK trial-a multidisciplinary Rehabilitation intervention for sudden Out-of-hospital Cardiac arrest survivors focusing on return-to-worK: a pragmatic randomized controlled trial protocol

INTRODUCTION

Most cardiac arrest survivors are classified with mild to moderate cognitive impairment; roughly, 50% experience long-term neurocognitive impairment. Postarrest challenges complicate participation in society and are associated with social issues such as failure to resume social activities and impaired return to work. The effectiveness of rehabilitation interventions for out-of-hospital cardiac arrest survivors are sparsely described, but the body of evidence describes high probabilities of survivors not returning to work, returning to jobs with modified job descriptions, returning to part-time employment, and often in combination with extensive unmet rehabilitation needs. Hence, there is a need to develop and test a pragmatic individual targeted intervention to facilitate return to work (RTW) in survivors of OHCA. The overall aim of the ROCK trial is to evaluate the effectiveness of a comprehensive individually tailored multidisciplinary rehabilitation intervention for survivors of OHCA on RTW compared to usual care.

METHODS AND ANALYSIS

The ROCK trial is a two-arm parallel group multicentre investigator-initiated pragmatic randomized controlled superiority trial with primary endpoint measured 12 months after the cardiac arrest. Adult survivors who were part of the labour force prior to the OCHA and had at least 2 years until they are qualified to receive retirement state pensions are eligible for inclusion. Survivors will be randomized 1:1 to usual care group or usual care plus a comprehensive tailored rehabilitation intervention focusing on supporting RTW. After comprehensive assessment of individual rehabilitation needs, the intervention is ongoingly coordinated within a multidisciplinary rehabilitation team, and the intervention can be delivered for up until 12 months. Data for the primary outcome will be obtained from the national register on social transfer payments. The primary outcome will be analysed using logistic regression assessing RTW status at 12 months adjusting for the intervention and age at OHCA, sex, marital status, and occupation prior to OHCA.

DISCUSSION

The ROCK trial is the first RCT to investigate the effectiveness of a rehabilitation intervention focusing on return to work after cardiac arrest.

Remote cognitive behavioral therapy utilizing an in-home virtual reality toolkit (Vx Therapy) reduces pain, anxiety, and depression in patients with chronic cervical and lumbar spondylytic pain: A potential alternative to opioids in multimodal pain management

Background Context

Virtual reality (VR) reduces pain through visual and auditory distraction without narcotic-related side effects or dependency. Cognitive behavioral therapy (CBT) improves pain-related disability and quality of life, but patient access remains a challenge. We hypothesized that in-home weekly CBT coordinated with daily use of a proprietary VR toolkit will reduce pain, anxiety, and depression for patients with non-operative chronic cervical and lumbar spondylitic pain with and without radiculopathy.

Methods

A total of 145 patients with chronic spondylitic pain (63 cervical, 46 noradicular lumbar, 36 radicular lumbar) were enrolled into a guided 14-week VR+CBT program (Vx Therapy) consisting of weekly encounters with a trained therapist and 50 modules. Pain/anxiety severity scores and time to pain recurrence were recorded prospectively by patients. PROMIS measures of overall daily pain intensity, behavior, interference, anxiety, and depression were recorded at baseline and conclusion of the program.

Results

A total of 52% of the 145 patients were male. The average (SD) age of the cohort was 51 (10.7) years (range: 24-76 years). Mean score for all PROMIS domains were significantly improved after 14 weeks of Vx Therapy (pain intensity 36±24 vs. 28±21, interference 39±25 vs. 24±21, behavior 35±21 vs. 25±16, anxiety 51±28 vs. 41±26, depression 58±32 vs. 48±32) for the entire cohort and each diagnosis group. Virtual reality acutely reduced pain on average by 33% (4.5±2.5 vs. 6.7±2.2, p<.05) across all 14 weeks, lasting a mean 2.8 hours after use. Duration of pain relief increased by the final vs. first month (4.5 hours vs. 2.5 hours, p<.05). Virtual reality acutely reduced anxiety on average by 46% (3.5±3 vs. 6.4±2, p<.05) across all 14 weeks lasting a mean 2.7 hours after use. The effect was similar for all 3 groups.

Conclusions

Fourteen weeks of a remote CBT guided in-home VR toolkit provided effective and sustained pain, anxiety, and depression relief in patients with chronic degenerative neck/back pain with and without radiculopathy. The non-invasive, non-pharmacological nature of Vx Therapy makes it an ideal option for pain management in the post-opioid epidemic era.

Trials We Cannot Trust: Investigating Their Impact on Systematic Reviews and Clinical Guidelines in Spinal Pain

We previously conducted an exploration of the trustworthiness of a group of clinical trials of cognitive-behavioral therapy and exercise in spinal pain. We identified multiple concerns in 8 trials, judging them untrustworthy. In this study, we systematically explored the impact of these trials ("index trials") on results, conclusions, and recommendations of systematic reviews and clinical practice guidelines (CPGs). We conducted forward citation tracking using Google Scholar and the citationchaser tool, searched the Guidelines International Network library and National Institute of Health and Care Excellence archive to June 2022 to identify systematic reviews and CPGs. We explored how index trials impacted their findings. Where reviews presented meta-analyses, we extracted or conducted sensitivity analyses for the outcomes of pain and disability, to explore how the exclusion of index trials affected effect estimates. We developed and applied an 'Impact Index' to categorize the extent to which index studies impacted their results. We included 32 unique reviews and 10 CPGs. None directly raised concerns regarding the veracity of the trials. Across meta-analyses (55 comparisons), the removal of index trials reduced effect sizes by a median of 58% (Inter Quartlie Range (IQR) 40-74). 85% of comparisons were classified as highly, 3% as moderately, and 11% as minimally impacted. Nine out of 10 reviews conducting narrative synthesis drew positive conclusions regarding the intervention tested. Nine out of 10 CPGs made positive recommendations for the intervention(s) evaluated. This cohort of trials, with concerns regarding trustworthiness, has substantially impacted the results of systematic reviews and guideline recommendations. PERSPECTIVE: We found that a group of trials of CBT for spinal pain with concerns relating to their trustworthiness has had substantial impacts on the analyses and conclusions of systematic reviews and clinical practice guidelines. This highlights the need for a greater focus on the trustworthiness of studies in evidence appraisal.

Home-Based Treatment for Chronic Pain Combining Neuromodulation, Computer-Assisted Training, and Telemonitoring in Patients With Breast Cancer: Protocol for a Rehabilitative Study

BACKGROUND

Chronic pain is a disabling symptom frequently reported in patients with breast cancer with a prevalence ranging from 25% to 60%, representing a major health issue. It has negative consequences on health status, causing psychological distress and affecting quality of life. Furthermore, the clinical management of chronic pain is often inadequate, and many patients do not benefit from the administration of pharmacological treatments. Alternative therapeutic options have been implemented to improve the psychophysical well-being of patients, including neuromodulation and complementary interventions.

OBJECTIVE

We aimed to investigate the effectiveness of a home care strategy combining computerized rehabilitation, transcranial direct current stimulation (tDCS), and remote telemonitoring via a web-based platform in patients with breast cancer suffering for chronic pain.

METHODS

A web-based structured survey aimed at monitoring chronic pain and its effect on psychological functions will be delivered to patients with breast cancer through social media and email. In total, 42 patients with breast cancer affected by chronic pain will be recruited during the medical screening visit. The patients will be randomly divided into 3 treatment groups that will carry out either tDCS only, exercise therapy only, or a combination of both over a 3-week period. All the treatments will be delivered at the patients' home through the use of a system including a tablet, wearable inertial sensors, and a tDCS programmable medical device. Using web-based questionnaires, the perception of pain (based on the pain self-efficacy questionnaire, visual analogue scale, pain catastrophizing scale, and brief pain inventory) and psychological variables (based on the hospital and anxiety depression scale and 12-item short form survey) will be assessed at the beginning of treatment, 1 week after the start of treatment, at the end of treatment, 1 month after the start of treatment, and 3 months after the start of treatment. The system's usability (based on the mobile app rating scale and system usability scale) and its involvement in the decision-making process (based on the 9-item shared decision-making questionnaire) will be also evaluated. Finally, at the end of the treatment, a digital focus group will be conducted with the 42 patients to explore their unexpressed needs and preferences concerning treatment.

RESULTS

The study project is scheduled to start in June 2023, and it is expected to be completed by August 2025.

CONCLUSIONS

We expect that the combination of tDCS and telemedicine programs will reduce pain perceived by patients with breast cancer and improve their mental well-being more effectively than single interventions. Furthermore, we assume that this home-based approach will also improve patients' participation in routine clinical care, reducing disparities in accessing health care processes. This integrated home care strategy could be useful for patients with breast cancer who cannot find relief from chronic pain with pharmacological treatments or for those who have limited access to care due to poor mobility or geographical barriers, thus increasing the patients' empowerment and reducing health care costs.

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

BACKGROUND

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

MAIN BODY

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

CONCLUSION

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

The effectiveness of cognitive behavioural therapy in chronic neck pain: A systematic review with meta-analysis

We evaluated the effects of Cognitive Behavioural Therapy (CBT) alone or with additional interventions on pain, disability, kinesiophobia, anxiety, stress, depression, quality of life, and catastrophizing of patients with chronic neck pain (CNP). Nineteen studies met the inclusion criteria, and fourteen studies were quantitatively analysed. Risk of bias was assessed using the PEDro scale and the certainty of evidence using the GRADE approach. Studies were pooled (where applicable) and subgroup analyses were performed for CNP, or whiplash associated disorders. Studies compared-directly or indirectly-CBT interventions to no treatment, conservative interventions such as exercise and/or physiotherapy, or multimodal interventions. We present effect estimates at 8-week, 12-week, 6-month, and 1-year follow-up. Low certainty evidence suggests a clinically significant pain reduction (short-term) favouring CBT with or without additional intervention compared to no intervention SMD = -0.73; 95%CI: -1.23 to -0.23). Very low and low certainty evidence suggest clinically significant improvements in kinesiophobia (very short-term SMD = -0.83; 95%CI: -1.28 to -0.39 and short-term SMD = -1.30, 95%CI: -1.60 to -0.99), depression SMD = -0.74, 95%CI: -1.35 to -0.14) and anxiety SMD = -0.76, 95%CI: -1.34 to -0.18) favouring a multimodal intervention with CBT (short-term) compared to other conservative interventions. Combining different types of CBT interventions resulted in potentially heterogeneous comparisons.

Mechanisms of change in digital cognitive behavioral therapy for depression in patients with chronic back pain: A mediation analysis of a multicenter randomized clinical trial

BACKGROUND

While there is evolving knowledge on change processes of digital cognitive behavioral therapy (CBT) in the treatment of depression, little is known about how these interventions produce therapeutic change in the comorbid constellation of chronic back pain (CBP). Here, we examined whether the effects of a digital intervention to treat depression in patients with CBP are mediated by three pain-related variables (i.e., pain self-efficacy, pain-related disability, pain intensity).

METHODS

This study is a secondary analysis of a randomized clinical trial conducted in routine care at 82 orthopedic clinics across Germany. In total, 209 adults with CBP and diagnosed depression (SCID interview) were randomly assigned to the intervention (n = 104) or treatment-as-usual (n = 105). Cross-lagged mediation models were estimated to investigate longitudinal mediation effects of putative mediators with depression symptom severity (PHQ-9) as primary outcome at post-treatment.

RESULTS

Longitudinal mediation effects were observed for pain self-efficacy (ß = -0.094, 95%-CI [-0.174, -0.014], p = 0.021) and pain-related disability (ß = -0.068, 95%-CI [-0.130, -0.001], p = 0.047). Furthermore, the hypothesized direction of the mediation effects was supported, reversed causation did not occur. Pain intensity did not reveal a mediation effect.

CONCLUSIONS

The results suggest a relevant role of pain self-efficacy and pain-related disability as change processes in the treatment of depression for patients with CBP in routine care. However, further research is needed to disclose potential reciprocal relationships of mediators, and to extend and specify our knowledge of the mechanisms of change in digital CBT for depression.

Psychological interventions for individuals with Ehlers-Danlos syndrome and hypermobility spectrum disorder: a scoping review

PURPOSE

To identify the nature and extent of the evidence on psychological interventions among individuals with Ehlers-Danlos Syndrome (EDS) and Hypermobility Spectrum Disorder (HSD).

MATERIALS AND METHODS

Eligible studies reported on psychological interventions for individuals of all ages with EDS and/or HSD. All studies published in English were included, with no restrictions to publication year or status. MEDLINE, CINAHL, EMBASE, and PsycINFO were searched. Two reviewers independently screened studies and abstracted data.

RESULTS

This scoping review included 10 studies reporting on EDS, HSD, or both. Only cohort studies and case studies were identified. Four studies investigated Cognitive Behavioural Therapy (CBT), one investigated Dialectical Behavioural Therapy (DBT), two investigated psychoeducation, two investigated Intensive Interdisciplinary Pain Treatment (IIPT), and one investigated Acceptance Commitment Therapy (ACT). Interventions targeted pain management, self-destructive behaviours, and related psychological issues (e.g., depression/anxiety). Sample sizes were small (n < 50) for most studies and interventions were generally poorly described.

CONCLUSIONS

There is a critical need for high-quality research surrounding psychological interventions for individuals with EDS/HSD. Psychological interventions for these individuals are understudied and existing studies lack validity. Researchers should investigate psychological interventions for individuals with all types of EDS/HSD with high-quality studies to validate findings from the existing studies.

Chronic Pain: A Case Application of a Novel Framework to Guide Interprofessional Assessment and Intervention in Primary Care

Background

Chronic pain is a complex condition that poses challenges in assessment and treatment. Primary care teams, especially in rural areas, may have a role in managing this population, providing interprofessional care to optimize patient outcomes. Tools are needed to aid these clinicians in assessing chronic pain.

Aims

The aim of this article is to present the case application of a clinical reasoning framework proposed by Walton and Elliott, which is used to identify drivers of chronic pain in a 61-year-old male patient with a remote history of spinal injury. Furthermore, it aims to demonstrate that an interprofessional, individualized intervention strategy can improve patient outcomes.

Methods

This case took place in a multidisciplinary primary care team in rural northern Ontario, Canada. An assessment was completed by the author, including collection of the patient's history, a medication review, and the use of multiple validated patient-reported outcome measures (PROMs), all of which were used in applying the framework.

Results

Three relevant drivers of his pain experience were identified: central nociplastic, cognitive/belief, and emotional/affective. A pharmacist and social worker then used multimodal interventions to address these drivers, which yielded improvements in scores on multiple validated pain measures but also improved the patient's self-reported quality of life.

Conclusions

A clinical reasoning framework can provide a basis for identifying drivers of chronic pain during assessment and guide primary care clinicians to targeted interventions. Broader applications of this framework by primary care providers could serve to increase capacity for managing chronic pain in Canada.

Comparison of the effectiveness of eHealth self-management interventions for pain between oncological and musculoskeletal populations: a systematic review with narrative synthesis

OBJECTIVES

The aim of this systematic review is to compare the effectiveness of eHealth self-management interventions on pain intensity between oncological and musculoskeletal populations and to examine barriers and facilitators of the use of eHealth self-management tools.

CONTENT

In March 2021, a systematic search of the literature was conducted using the databases PubMed and Web of Science. Studies that investigated the effect of eHealth self-management interventions on pain intensity in an oncological and/or a musculoskeletal population were included.

SUMMARY

No study was found with a direct comparison of the two populations. Of the ten included studies, only one (musculoskeletal) found a significant interaction effect in favor of the eHealth program and three (musculoskeletal and breast cancer) showed a significant time-effect of the eHealth intervention. In both populations user-friendliness of the tool was considered as a facilitator, the length of the program and the lack of an in-person session as barrier. Due to the absence of a direct comparison, no conclusion can be made on how the effectiveness differs between both populations.

OUTLOOK

Further research should incorporate patient-experienced barriers and facilitators and there is a high need of studies making the direct comparison of the effect of an eHealth self-management intervention on pain intensity in an oncological vs. a MSK population.

Effectiveness of cognitive behavioral therapy for patients after total knee arthroplasty: a systematic review and meta-analysis

Total knee arthroplasty (TKA) is considered a common surgical option in patients with end-stage osteoarthritis of the knee. This systematic review and meta-analysis aimed to determine the effectiveness of cognitive behavioral therapy (CBT) for patients after TKA. PubMed, EMBASE, the Cochrane Library, Web of Science and CINAHL were searched for randomized controlled trials (RCTs) from inception to 20 August 2021. Included studies were evaluated with the Cochrane risk-of-bias tool. Six RCTs were included. Our study results demonstrated that a significant reduction in pain catastrophing was seen in patients receiving CBT at post-intervention (SMD -0.48, 95% CI = -0.72 to -0.23, I2 17.2%, p = 0.00) but not in 3-month or 12-month follow-up. There were no significant differences between CBT and usual-care patients regarding pain intensity or knee function at different time-points. This is the first time that meta-analysis has been conducted to determine the effectiveness of CBT for patients after TKA. It is necessary to conduct longer follow-ups, include larger samples and conduct rigorous RCTs to further explore this issue.

Effect of a Behavioral Therapy-Based Virtual Reality Application on Quality of Life in Chronic Low Back Pain

OBJECTIVES

Low back pain is the leading cause of years lived with disability with a large impact on quality of life and resistance to a broad array of current treatments. This study aimed to investigate the effect of a novel self-administered behavioral therapy-based virtual reality (VR) application on the quality of life of patients with nonspecific chronic low back pain (CLBP).

METHODS

A pilot randomized controlled trial was conducted in adults with nonspecific CLBP with moderate to severe pain, waiting for treatment in a teaching hospital-based pain clinic. The intervention group used a self-administered behavioral therapy-based VR application for at least 10 minutes daily for 4 weeks. The control group received standard care. The primary outcome was quality of life at 4 weeks measured by the short form-12 physical and mental scores. Secondary outcomes were daily worst and least pain, pain coping strategies, activities of daily living, positive health, anxiety, and depression. Discontinuation of therapy and adverse events were analyzed as well.

RESULTS

Forty-one patients were included. One patient withdrew due to personal reasons. No significant treatment effect was found for the short form-12 physical score (mean difference: 2.6 points; 95% CI: -5.60 to 0.48) and mental score (-1.75; -6.04 to 2.53) at 4 weeks. There was a significant treatment effect for daily "worst pain score" ( F [1, 91.425] = 33.3, P < 0.001) and "least pain score" ( F [1, 30.069] = 11.5, P = 0.002). Three patients reported mild and temporary dizziness.

DISCUSSION

Four weeks of self-administered VR for CLBP does not improve quality of life, however, it may positively affect daily pain experience.

A Causal View of the Role and Potential Limitations of Capitation in Promoting Whole Health System Performance

For several decades, health systems in developed countries have faced rapidly rising healthcare costs without concomitant improvements in health outcomes. Fee for service (FFS) reimbursement mechanisms (RMs), where health systems are paid based on volume, contribute to this trend. In Singapore, the public health service is trying to curb rising healthcare costs by transitioning from a volume-based RM to a capitated payment for a population within a geographical catchment area. To provide insight into the implications of this transition, we developed a causal loop diagram (CLD) to represent a causal hypothesis of the complex relationship between RM and health system performance. The CLD was developed with input from government policymakers, healthcare institution administrators, and healthcare providers. This work highlights that the causal relationships between government, provider organizations, and physicians involve numerous feedback loops that drive the mix of health services. The CLD clarifies that a FFS RM incentivizes high margin services irrespective of their health benefits. While capitation has the potential to mitigate this reinforcing phenomenon, it is not sufficient to promote service value. This suggests the need to establish robust mechanisms to govern common pool resources while minimizing adverse secondary effects.

The effectiveness of cognitive behavioural therapy for patients with concurrent hand and psychological disorders

We investigated the effectiveness of cognitive behavioural therapy (CBT) for patients with psychological disorders thought to be influencing recovery from elective and traumatic hand conditions. Demographic data and psychological assessment scores (Primary Health Questionnaire 9 (PHQ9), General Anxiety Disorder Assessment (GAD7), Impact of Event Scale (IES)) were prospectively collected before and after CBT treatment. One hundred and fourteen patients underwent CBT with 81 completing treatment. Full data was available for 78 (68%) patients. Mean age was 43 (range 13-84) and 63% were women. Sixty-one per cent had sustained a traumatic hand injury. PHQ9, GAD7 and IES scores decreased significantly following treatment. Many patients with hand conditions have associated psychological problems that may influence outcome. CBT in a hand unit setting appears to be an effective treatment. Further research with a control group should investigate whether CBT improves psychological health or if this may occur as patients recover from their physical hand disorder regardless of CBT.Level of evidence: IV.

Functional and psychosocial impact of COVID-19 pandemic on rheumatic patients' quality of life in Saudi Arabia

PURPOSE

The COVID-19 pandemic might add to the stressors experienced by people living with rheumatic diseases. This study aimed to examine rheumatic patients' functional and psychosocial states during the pandemic and assess its impact on their quality of life.

METHODS

Our time-series study included a patient-centered electronic survey, sampling adult rheumatic patients living in Saudi Arabia at different time points from March to August 2020. Patient-reported outcomes included physical function, anxiety, depression, fatigue, sleep disturbance, ability to participate in social roles, and pain interference domains were measured using the Patient-Reported Outcomes Measurement Information System (PROMIS-29 Profile v2.1).

RESULTS

A total of 1278 respondents were enrolled. Results showed significant variation in patients' experiences. Our analyses revealed that the physical well-being of rheumatic patients was significantly impacted, and such effect was persistent over time irrespective of public health measures to control the COVID-19 outbreak.

CONCLUSION

Our findings consistently demonstrated the need for psychological and social consideration to improve rheumatic patients' quality of life. Nevertheless, there is still a lot to be learned about the extent of COVID-19 impact on rheumatic patients and the implications it has on long-term disease outcomes.

Role of Occupational Therapy in Pain Management

This new position statement from the American Occupational Therapy Association (AOTA) describes occupational therapy's role in pain management. AOTA asserts that occupational therapy practitioners are distinctly prepared to work independently and to contribute to interprofessional teams in the treatment of pain. Practitioners strive to ensure active engagement in meaningful occupations for clients at risk for and affected by pain.

Role of Occupational Therapy in Pain Management

The American Occupational Therapy Association (AOTA) asserts that occupational therapists and occupational therapy assistants, collectively referred to as occupational therapy practitioners (AOTA, 2020b), are distinctly prepared to work independently and to contribute to interprofessional teams in the treatment of pain. Occupational therapy practitioners work to ensure active engagement in meaningful occupations for "persons, groups, or populations (i.e., the client)" (AOTA, 2020b, p. 1) at risk for and affected by pain.

Managing Chronic Neuropathic Pain: Recent Advances and New Challenges

Aim. Neuropathic pain affects 7–10% of the population, with most of the patients receiving inadequate and incomplete treatment. Owing to the high financial burden and the poor quality of life of the patients and their caretakers, there is a dire need to address the challenges in diagnosing and treating chronic neuropathic pain. Methods. This literature review was conducted to review novel treatments and related challenges through a systematic search from sources such as PubMed, Google Scholar with the combination of MESH words such as neuropathic pain, management of neuropathic pain. Articles from non-English literature, reports without human subjects, animal studies, and abstracts/posters were excluded. However, human studies and studies published in English were included. Result. This review article discusses novel treatment modalities while acknowledging the challenges medical workers face while encountering neuropathic pain. Despite the recent advances in diagnosis and treatment modalities, several challenges still exist. Hence, there is still a need to explore the various treatment modalities, emphasizing the cause and underlying pathophysiology of neuropathic pain. Conclusion. We recommend integrated multimodal treatment with the current treatment facility, including various medical disciplines. However, a personalized approach would work the best depending on the ’patient’s medical history. Therefore, this article recommends an integrated, cause-specific, cost-effective approach to address this problem of chronic neuropathic pain.

The clinician's guide to prevention and treatment of osteoporosis

Osteoporosis is the most common metabolic bone disease in the USA and the world. It is a subclinical condition until complicated by fracture(s). These fractures place an enormous medical and personal burden on individuals who suffer from them and take a significant economic toll. Any new fracture in an adult aged 50 years or older signifies imminent elevated risk for subsequent fractures, particularly in the year following the initial fracture. What a patient perceives as an unfortunate accident may be seen as a sentinel event indicative of bone fragility and increased future fracture risk even when the result of considerable trauma. Clinical or subclinical vertebral fractures, the most common type of osteoporotic fractures, are associated with a 5-fold increased risk for additional vertebral fractures and a 2- to 3-fold increased risk for fractures at other sites. Untreated osteoporosis can lead to a vicious cycle of recurrent fracture(s), often resulting in disability and premature death. In appropriate patients, treatment with effective antifracture medication prevents fractures and improves outcomes. Primary care providers and medical specialists are critical gatekeepers who can identify fractures and initiate proven osteoporosis interventions. Osteoporosis detection, diagnosis, and treatment should be routine practice in all adult healthcare settings. The Bone Health and Osteoporosis Foundation (BHOF) - formerly the National Osteoporosis Foundation - first published the Clinician's Guide in 1999 to provide accurate information on osteoporosis prevention and treatment. Since that time, significant improvements have been made in diagnostic technologies and treatments for osteoporosis. Despite these advances, a disturbing gap persists in patient care. At-risk patients are often not screened to establish fracture probability and not educated about fracture prevention. Most concerning, the majority of highest risk women and men who have a fracture(s) are not diagnosed and do not receive effective, FDA-approved therapies. Even those prescribed appropriate therapy are unlikely to take the medication as prescribed. The Clinician's Guide offers concise recommendations regarding prevention, risk assessment, diagnosis, and treatment of osteoporosis in postmenopausal women and men aged 50 years and older. It includes indications for bone densitometry as well as fracture risk thresholds for pharmacologic intervention. Current medications build bone and/or decrease bone breakdown and dramatically reduce incident fractures. All antifracture therapeutics treat but do not cure the disease. Skeletal deterioration resumes sooner or later when a medication is discontinued-sooner for nonbisphosphonates and later for bisphosphonates. Even if normal BMD is achieved, osteoporosis and elevated risk for fracture are still present. The diagnosis of osteoporosis persists even if subsequent DXA T-scores are above - 2.5. Ongoing monitoring and strategic interventions will be necessary if fractures are to be avoided. In addition to pharmacotherapy, adequate intake of calcium and vitamin D, avoidance of smoking and excessive alcohol intake, weight-bearing and resistance-training exercise, and fall prevention are included in the fracture prevention armamentarium. Where possible, recommendations in this guide are based on evidence from RCTs; however, relevant published data and guidance from expert clinical experience provides the basis for recommendations in those areas where RCT evidence is currently deficient or not applicable to the many osteoporosis patients not considered for RCT participation due to age and morbidity.

Neurophysiology of hypnosis in chronic pain: A review of recent literature

Chronic pain is a complex phenomenon which includes biological, psychological, and socio-professional factors that undermine patients' everyday life. Currently, only few patients significantly benefit from pharmacological treatments and many have to stop them because of negative side effects. Moreover, no medication or treatment addresses all aspects of chronic pain at once (i.e., sensations, emotions, behaviors, and cognitions), positioning chronic pain as an important public health issue and thus contributing to high health-care costs. Consequently, patients and health-care providers are increasingly turning to complementary non-pharmacological techniques such as hypnosis. Clinical research has demonstrated a decrease of pain perception, pain interference, depression and anxiety, and an increase in global quality of life when patients with chronic pain have benefited from hypnosis learning. Neuroimaging studies offer a possible explanation of these results by focusing on neural processes of pain modulation in chronic pain patients' brain. Studies conducted with chronic pain patients showed a modulation of pain matrix activity during hypnosis with a specific involvement of the anterior cingulate cortex (related to emotional and cognitive processing of pain). Therefore, hypnosis seems to act upon regions underlying emotion and cognition, with an influence on pain perception and emotional regulation. In this review, we propose to carry out a review of the recent literature on hypnosis in chronic pain management. A better understanding of the beneficial effects of hypnosis on chronic pain and its neurophysiology should enable more systematic use of this technique in the management of this complex health problem.

Psychosocial factors associated with disability in patients with non-specific chronic low back pain: A cross-sectional study

INTRODUCTION AND OBJECTIVES

Chronic low back pain is the main cause of disability worldwide, generating high costs for society. To evaluate the prevalence of disability in patients with non-specific chronic low back pain and associated factors, including the impacts of low back pain and psychosocial factors linked to kinesiophobia, catastrophism, anxiety, and depression.

PATIENTS

A cross-sectional study was carried out with 108 adult individuals who had non-specific chronic low back pain. The patients answered previously validated questionnaires, namely the Brief Pain Inventory, the Roland-Morris Disability Questionnaire, the Pain Catastrophizing Scale, the Tampa Kinesiophobia Scale, and the Hospital Anxiety and Depression Scale.

RESULTS

The prevalence of disability observed was 65.7%, with the mean disability score being 15.7±5.3 points in the Roland-Morris Disability Questionnaire. Although pain intensity and other domains of the Brief Pain Inventory, like anxiety, depression, and severe kinesiophobia were significant in the bivariate analyses, they were not associated with disability in the multivariate analysis. Only catastrophic thoughts (prevalence ratio [PR]=1.19; 95% confidence interval [CI]: 1.07-1.32), and the 'walking' domain (PR=1.08; 95% CI: 1.03-1.14) remained statistically associated with disability.

CONCLUSION

Pain catastrophization and impact on gait were associated with disability in individuals with non-specific chronic low back pain. Motor control thoughts and behaviors during functional activities were considered to be relevant aspects for the better assessment and treatment of these patients.

The efficacy of cognitive behavioral therapy-based intervention on patients with diabetes: A meta-analysis

AIMS

This meta-analysis aims to update former meta-analyses from randomized controlled trials (RCT) focused on the efficacy of CBT for diabetes.

METHODS

Five databases were searched for RCTs. Primary outcomes were glycated hemoglobin (HbA_1c), fasting blood glucose (FBS), systolic blood pressure (SBP), diastolic blood pressure (DBP), and body mass index (BMI). Secondary outcomes were depression, anxiety and distress symptoms, quality of life, sleep quality.

RESULTS

32 RCTs were included. Results revealed that CBT could reduce HbA_1c: -0.14% (95% CI: -0.25 to -0.02%, P = 0.020); FBS: -15.48 mg/dl (95% CI: -30.16 to -0.81 mg/dl, P = 0.040); DBP: -2.88 mmHg (95% CI: -4.08 to -1.69 mmHg, P < 0.001); depression symptoms: -0.90 (95% CI: -1.22 to -0.57, P < 0.001); anxiety symptoms: -0.28 (95% CI: -0.50 to -0.07, P = 0.009); improve sleep quality: -0.92 (95% CI: -1.77 to -0.07, P = 0.030). Subgroup analysis indicated that CBT has siginificantly reduced HbA_1c when delivered as a group-based and face-to-face method, and psycho-education, behavioral, cognitive, goal-setting, homework assignment strategies were applied as central strategies.

CONCLUSION

CBT was an effective treatment for diabetes patients, significantly reduced their HbA_1c, FBS, DBP, depression and anxiety symptoms, and improved sleep quality.

A Brief Psychological Intervention for Chronic Pain in Primary Care: Examining Long-term Effects from a Pilot Randomized Clinical Trial

BACKGROUND

Despite the existence of evidence-based psychological interventions for pain management, there are barriers that interfere with treatment engagement. A brief intervention integrated into primary care reduced barriers and showed promising benefits from pre- to post-intervention. However, it is unknown whether a brief intervention can provide long-term effects. The purpose of this study was to examine whether a brief psychological intervention offered benefits in pain severity, pain interference, pain catastrophizing, and depressive symptoms at 1- and 6-month follow-ups.

METHODS

The majority of participants who enrolled in a pilot randomized clinical trial of a 5-session psychological intervention for chronic pain in primary care completed the 1-month (n= 54; 90%) and 6-month follow-ups (n= 50; 83.3%). Participants completed measures of pain severity, pain interference, pain catastrophizing, and depressive symptoms.

RESULTS

From baseline to the 6-month follow-up, those in the intervention group had significantly better outcomes for pain severity (p= .01) and pain catastrophizing (p= .003) compared to the control group. There were no significant differences between the intervention and control groups for pain interference and depression. The percentage of patients in the intervention experiencing clinically significant improvement across all outcomes was higher than the control group.

CONCLUSIONS

Findings suggest that a brief psychological intervention for chronic pain in primary care may offer longer-term benefits similar to that of lengthier interventions. Future studies should examine this through a randomized clinical trial with a larger sample size.

Learning the neurobiology of pain: A scoping review of pain education from an instructional design perspective

OBJECTIVES

Learning modern pain biology concepts can improve important clinical outcomes for people with chronic pain. The primary purpose of this scoping review is to examine and report characteristics of chronic musculoskeletal pain education programs from an instructional design perspective.

METHODS

Following PRISMA-ScR guidelines, PubMed, Medline, and CINAHL databases were systematically searched. Articles included expert recommendations and those reporting pain education programs used in clinical trials enrolling adults with chronic neuromusculoskeletal pain and published in English between 1990 and 2021. Three authors independently evaluated articles for eligibility through title, abstract, and full text review. Instructional design characteristics such as learning outcomes, support materials, learning assessment methods, and key concepts communicated were summarized.

RESULTS

The search revealed 5260 articles of which 40 were included: 27 clinical studies, 7 expert recommendations, and 6 articles reporting on pain education from participant perspectives. Detailed reporting of instructional design characteristics informing replication in subsequent studies is sparse. Most included trials used only lecture and did not assess participant learning.

CONCLUSIONS

More comprehensive reporting of pain education programs is needed to facilitate replicability.

PRACTICAL IMPLICATIONS

This article proposes detailed and standardized reporting of trials using pain education programs employing a modified version of the TIDieR checklist.

Engaging with EPIO, a digital pain self-management program: a qualitative study

Background

Chronic pain conditions entail significant personal and societal burdens and improved outreach of evidence-based pain self-management programs are needed. Digital cognitive-behavioral self-management interventions have shown promise. However, evidence is still scarce and several challenges with such interventions for chronic pain exist. Exploring patients' experiences and engagement with digital interventions may be an essential step towards developing meaningful digital self-management interventions for those living with chronic pain.

Objectives

This study aimed to gain insight into the experiences of people with chronic pain when engaging with EPIO, an application (app)-based cognitive-behavioral pain self-management intervention program.

Methods

Participants (N = 50) living with chronic pain received access to the EPIO intervention in a feasibility pilot-study for 3 months. During this time, all participants received a follow-up phone call at 2–3 weeks, and a subsample (n = 15) also participated in individual semi-structured interviews after 3 months. A qualitative design was used and thematic analysis was employed aiming to capture participants’ experiences when engaging with the EPIO intervention program.

Results

Findings identifying program-related experiences and engagement were organized into three main topics, each with three sub-themes: (1) Engaging with EPIO; motivation to learn, fostering joy and enthusiasm, and helpful reminders and personalization, (2) Coping with pain in everyday life; awareness, practice and using EPIO in everyday life, and (3) The value of engaging with the EPIO program; EPIO – a friend, making peace with the presence of pain, and fostering communication and social support.

Conclusions

This qualitative study explored participants’ experiences and engagement with EPIO, a digital self-management intervention program for people living with chronic pain. Findings identified valued aspects related to motivation for engagement, and showed how such a program may be incorporated into daily life, and encourage a sense of acceptance, social support and relatedness. The findings highlight vital components for facilitating digital program engagement and use in support of self-management for people living with chronic pain.

Attachment Style and Burn Pain

Pain management is a challenge when treating patients with burn injuries. Understanding the behavioral and interpersonal aspects of the experience of burn pain may aid in its management. Attachment style-which influences how an individual relates to other people-is one aspect that may affect the experience of burn pain. Past research has shown a relationship between an individual's attachment style and certain types of pain and disorders. The study builds upon that past work to investigate specifically how attachment style affects the experience of acute burn pain. Participants were at least 18 years old and admitted to an American Burn Association verified burn center with burns encompassing 30% or less total body surface area. Participants completed demographic questionnaires and a standardized measure of adult attachment style. Data regarding use of analgesics, daily pain scores, and burn-related information were collected through medical chart review. Participants who reported a secure attachment style required less pain medication and reported less pain compared with participants who reported an insecure attachment style. There was no difference in burn-related variables between participants with secure and insecure attachment styles, suggesting that these differences were not due to burn-related factors. Attachment, therefore, may play a role in an individual's perception of acute burn pain, which impacts analgesic requirements needed to manage the pain. These results have potential implications for the use of psychosocial interventions to reduce the experience of pain and the amount of pain medication needed to manage acute burn pain.

Associations of Internalized Skin Bias With Age, Adverse Psychopathology, and Health-Related Quality of Life Among Patients With Hidradenitis Suppurativa: A Cross-sectional Analysis

Importance

Hidradenitis suppurativa (HS) is a chronic autoinflammatory disease that is highly associated with affective disorders such as depression and anxiety. Recent studies have shown that patients with HS may also endorse high levels of internalized skin bias (ISB). This redirection of skin disease-related social stigma toward oneself may also play an important role in the associations between adverse psychopathology (eg, depression, anxiety) and health-related quality of life (HRQOL).

Objectives

To evaluate the associations of ISB with other core outcomes in HS and to determine if ISB may mediate the associations between adverse psychopathological outcomes and impaired HRQOL.

Design, Setting, and Participants

A cross-sectional study of adult patients with HS recruited from 1 academic medical center as well as through virtual social and recruitment networks. Eligible participants completed an online survey comprised of 4 survey instruments along with demographic and disease history information from April 1, 2021, to July 15, 2021.

Main Outcomes and Measures

Measures included the Internalized Skin Bias Questionnaire (ISBQ), Burns Anxiety Inventory, the Beck Depression Inventory-II, the Hidradenitis Suppurativa Quality of Life (HiSQOL) instrument, along with demographic and disease history information. The primary outcome was HRQOL as measured by the HiSQOL. Data were analyzed in July through August 2021.

Results

The survey was completed by 230 of 279 patients (82.4%; mean [SD] age, 39.2 [11.2] years; 209 [90.9%] identified as female, 203 [88.7%] as not Hispanic, 178 [77.7%] as White). Depression and anxiety were shown to be a substantial burden in this sample, with 56.5% of participants' scores qualifying for moderate or greater anxiety and 45.7% moderate or greater depression. The mean (SD) HRQOL scores were moderately high at 34.5 (16.7), indicating strong levels of impairment. There was a moderate correlation between ISBQ score and depression (r = 0.67); and fair correlations with HRQOL (r = 0.52) and anxiety (r = 0.56). Therefore, ISB appears to positively mediate the associations between depression and anxiety (estimated proportions of total effect that were mediated, 38.7% and 24.9%, respectively) and HRQOL. After controlling for age, disease severity, and disease duration, both ISB and anxiety were positive predictors of impaired HRQOL.

Conclusions and Relevance

This cross-sectional study found that ISB was associated with adverse psychopathology and impaired HRQOL in patients with HS. Furthermore, ISB appears to mediate the associations of depression and anxiety with HRQOL. Future studies are needed to design interventions targeted at addressing adverse psychopathology associated with ISB and improving HRQOL and well-being for patients with HS.

Internalized skin bias: Validation study to explore the impact of the internalization of social stigma on those with hidradenitis suppurativa

BACKGROUND

Hidradenitis suppurativa (HS) is a chronic auto-inflammatory disease that is highly associated with adverse psychopathology and impaired body image. Previous studies show that patients with HS are also impacted by social stigma associated with their skin disease. Over time, these experiences can influence the way in which patients feel about themselves, leading to internalized skin bias (ISB).

OBJECTIVES

To evaluate the validity and reliability of the Internalized Skin Bias Questionnaire (ISBQ) in an HS population, and to determine the association of this instrument with markers of HS severity.

METHODS

A cross-sectional survey with 72-hour retest was sent to adult patients with HS from March to November 2021. Reliability for the ISBQ was evaluated using Cronbach's alpha and the Concordance Correlation Coefficient (CCC). Construct validity was evaluated using Pearson Correlation Coefficients with similar measures.

RESULTS

Internal consistency for the ISBQ instrument was 0.89 with a CCC of 0.88. The ISBQ had moderate correlation (r = 0.63) with the experienced skin stigma questionnaire as well as the BDI-II (r = 0.66) and the psychosocial subscale of the HiSQOL (r = 0.65). ISBQ scores differed significantly across different stages of disease severity (p=0.04). There was no significant difference between those with different durations of disease (p=0.47).

CONCLUSIONS

This study shows that the ISBQ is a valid and reliable instrument that can be used to assess the psychosocial construct of ISB especially in a population of HS patients. Further, ISB places a prevalent negative impact on the psychopathology of patients with HS.

How Is the Probability of Reporting Various Levels of Pain 12 Months After Noncatastrophic Injuries Associated with the Level of Peritraumatic Distress?

BACKGROUND

Psychological factors have been shown to be consistent predictors of chronic pain in people with musculoskeletal injuries. However, few prognostic studies have considered multiple risk factors including peritraumatic distress. In addition, previous research has not considered that the associations between peritraumatic distress and pain levels can vary across pain outcomes.

QUESTION/PURPOSE

To determine whether an easily measurable level of baseline distress is associated with pain levels 1 year after noncatastrophic traumatic injuries when the outcome to be assessed is not normally distributed.

METHODS

This was a prospective cohort study. The data were captured from two cohorts in London, Ontario, Canada, and Chicago, IL, USA. Participants were adults with acute noncatastrophic (that is, not treated with surgery or hospitalization) musculoskeletal injuries of any etiology with various injury locations (60% [145 of 241] spinal and 40% [96 of 241] peripheral) that presented to local urgent care centers. Other inclusion criteria included English/French speakers and having no other disorder that would affect their pain levels. In total, between the years 2015 and 2018, 241 participants were recruited based on the inclusion criteria. Ninety-three percent (225 of 241) of participants provided baseline data, and of these, 48% (109 of 225) were lost to follow-up in 1 year. Based on a complete case approach, this study included 116 participants who ranged in age from 18 to 66 years and 69% (80) of whom were women. The Traumatic Injuries Distress Scale (TIDS) was used to evaluate distress at baseline (within 4 weeks of injury). The TIDS is a validated, reliable 12-item risk prognosis screening tool that takes less than 3 minutes to complete with questions regarding uncontrolled pain, negative affect, and intrusion/hyperarousal. The minimum and maximum possible scores are 0 and 24, with higher scores indicating higher levels of distress. The Numeric Pain Rating Scale (NPRS) was used to assess the pain level at baseline and again 12 months postinjury. To complete the NPRS, participants rate the severity of their pain on a scale of 0 to 10, with 0 indicating no pain and 10 indicating the worst pain imaginable. NPRS scores of 1 to 3 indicate mild pain, 4 to 6 indicate moderate pain and 7 or higher indicate severe pain. As a preliminary analysis, to assess whether the participants as a group experienced recovery, a paired samples t-test was used to compare NPRS scores at baseline and 12 months. In all, 52% (60 of 116) of participants reported no pain (NPRS = 0), and mean pain intensity scores improved from 4.8 ± 2.1 at baseline to 1.6 ± 1.6 at 12-month follow-up (p < 0.001). Quantile regression was used to describe the association between baseline distress and pain levels 1 year after the injury. This technique was used because it reveals the relationships at different quantiles of the pain outcome distribution.

RESULTS

The results indicate some people (52% [60 of 116]) recovered regardless of their baseline level of distress (30th quantile of the NPRS: β = 0). However, in those with persisting pain, higher levels of baseline distress are associated with greater levels of pain 12 months after the injury (50th quantile of the NPRS: β = 0.11; p = 0.01; 70th quantile of the NPRS: β = 0.27; p < 0.001; 90th quantile of the NPRS: β = 0.31; p = 0.01). According to this model, with a baseline TIDS score of 5, there is 10% probability that patients will report moderate or greater levels of pain (4 or higher of 10) 12 months later. This probability then increases as the TIDS score increases. For instance, at a score of 13 on the TIDS, the probability of a patient reporting moderate or higher levels of pain increases to 30%, and the probability of reporting severe pain (higher than 6 of 10) is 10%.

CONCLUSION

Clinicians and surgeons in orthopaedic settings can screen for the presence of peritraumatic distress using the TIDS, which is an easily administered tool that does not require extensive knowledge of psychology, and by using it they can identify those with higher levels of distress who are more likely to have persistent, long-term pain. A score of 4 or less indicates a low risk of persistent pain, a score between 5 and 12 (endpoints included) indicates moderate risk, and a score of 13 or higher indicates high risk. Future studies should investigate whether certain immediate interventions for peritraumatic distress in the aftermath of trauma can decrease the likelihood that a patient will develop chronic pain after injury. As an analysis technique, quantile regression is useful to assess complex associations in many orthopaedic settings in which a certain outcome is expected to occur in most patients leading to non-normally distributed data.

Impacts of Cognitive Behavioral Therapy for Insomnia and Pain on Sleep in Women with Gynecologic Malignancies: A Randomized Controlled Trial

Insomnia is an adverse cancer outcome impacting mood, pain, quality of life, and mortality in cancer patients. Cognitive Behavioral Therapy (CBT) is an evidence-based treatment for diverse psychophysiological disorders, including pain and insomnia. Primarily studied in breast cancer, there is limited research on CBT within gynecology oncology. This study examined CBT effects on subjective and behavioral sleep outcomes: Sleep Efficiency (SE), Sleep Quality (SQ), Total Wake Time (TWT), Sleep Onset Latency (SOL), and Wake After Sleep Onset (WASO). Thirty-five women with insomnia status/post-surgery for gynecologic cancer were randomized to CBT for insomnia and pain (CBTi.p., N = 18) or Psychoeducation (N = 17). Sleep was assessed via sleep diaries and wrist-worn actigraphy at baseline (T1), post-intervention (T2), and two-month follow-up (T3). Intent-to-treat analyses utilizing mixed linear modeling examined longitudinal group differences on sleep controlling for age and advanced cancer. All participants demonstrated improved (1) subjective SE (0.5, p < .01), SOL (-1.2, p < .01), TWT (-1.2, p < .01), and (2) behavioral SE (0.1, p = .02), TWT (-1.2, p = .03), WASO (-0.8, p < .01) across time. Group-level time trends were indicative of higher subjective SE (6.8, p = .02), lower TWT (-40.3, p = .01), and lower SOL (-13.0, p = .05) in CBTi.p. compared to Psychoeducation. Supplemental analyses examining clinical significance and acute treatment effects demonstrated clinical improvements in SE (T1), TWT (T2, T3), and SOL (T3). Remaining effects were not significant. Despite lacking power to detect interaction effects, CBTi.p. clinically improved sleep in women with gynecologic cancers and insomnia during the active treatment phase. Future research will focus on developing larger trials within underserved populations.

Cognitive behavioral therapy cannot relieve postoperative pain and improve joint function after total knee arthroplasty in patients aged 70 years and older

PURPOSE

A randomized controlled trial was conducted to investigate whether cognitive behavioral therapy (CBT) can improve postoperative pain, knee function, and negative emotion in patients aged 70 years and older who underwent total knee arthroplasty (TKA).

METHODS

This study used randomized, parallel group, controlled trial to divide the included 90 patients into CBT group and usual care group. The primary outcome measure of the study was the Visual Analogue Scale (VAS) at activity. The secondary outcome measures included the Self-Rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS), Knee Range of Motion (ROM), Oxford Knee Score (OKS), Hospital for Special Surgery Knee Rating Scale (HSS), analgesics dose, and postoperative complications.

RESULTS

83 patients who met the criteria were randomized into CBT group and usual care group. In the SAS, score of the CBT group decreased by 4.3 points at 7th day and 8.2 at 14th day after surgery with respect to preoperative SAS score, the usual care group increased by 1.5 at 7th day and decreased 1.1 at 14th day, and tended to be similar at 3rd month after surgery. There were no significant differences at 7th and 14th day in SDS, however, score of the CBT group was 5.8 and the usual care group was 1.9 at 3rd month after surgery. No statistically significant differences in VAS at activity, ROM, OKS, HSS, analgesics frequency, and postoperative complications between two groups.

CONCLUSIONS

CBT was superior to usual care group in relieving anxiety at 7th day and 14th day, and depression at 3rd month, however, CBT cannot relieve postoperative pain and improve joint function after TKA in patients aged 70 years and older.

Effectiveness of cognitive behavioral therapy-based interventions on health outcomes in patients with coronary heart disease: A meta-analysis

BACKGROUND

Recently, the efficacy of cognitive behavioral therapy (CBT)-based intervention on health outcomes in patients with coronary heart disease (CHD) has been recognized in randomized controlled trials (RCTs), but no comprehensive systematic review has been conducted. To address this research gap, our study aimed to evaluate whether comprehensive CBT-based interventions positively affect health outcomes in CHD patients. It was hypothesized that CBT-based interventions are effective in: (1) Reducing depression, anxiety, and stress symptoms; (2) Reducing body mass index, blood pressure, and lipid levels; and (3) Improving quality of life, and exercise endurance.

AIM

To verify the effectiveness of CBT-based interventions on CHD patients through a meta-analysis of previous publications.

METHODS

Relevant RCTs published in English were obtained by searching electronic databases, including PubMed, Embase, Cochrane Central Register of Controlled Trials, Scopus, and Proquest, with the retrieval time from inception to August 2020. The primary outcomes were psychological factors (depression, anxiety, and stress symptoms), physiological factors (body mass index, blood pressure, blood lipids). The secondary outcomes included quality of life and exercise endurance. We used Review Manager 5.3 to conduct the meta-analysis and used the Physiotherapy Evidence Database tool to evaluate the quality of studies.

RESULTS

A total of 22 RCTs comprising 4991 patients with CHD were included in the systematic review and meta-analysis. The main analysis revealed that CBT-based intervention can reduce depression symptoms: -2.00 [95% confidence interval (CI): -2.83 to -1.16, P < 0.001]; anxiety symptoms: -2.07 (95%CI: -3.39 to -0.75, P = 0.002); stress symptoms: -3.33 (95%CI: -4.23 to -2.44, P < 0.001); body mass index: -0.47 (95%CI: -0.81 to -0.13, P = 0.006); and improve physical functioning: 3.36 (95%CI: 1.63 to 5.10, P = 0.000) and mental functioning: 6.91 (95%CI: 4.10 to 9.73, P < 0.001). Moreover, subgroup analysis results showed that CBT-based interventions were more effective for symptoms of depression and anxiety in CHD patients when individual, as opposed to group treatment, and psycho-education, behavioral and cognitive strategies were applied as the core treatment approaches.

CONCLUSION

CBT-based interventions are effective treatment strategies for CHD patients, significantly improving their symptoms of depression, anxiety and stress, body mass index, and health-related quality of life.

Comprehensive pain management as a frontline treatment to address the opioid crisis

BACKGROUND

The opioid crisis continues to devastate individuals and communities in the United States and abroad. While there have been several measures to address the over-prescription of opioid analgesics, the number of overdose deaths related to prescription opioids has not changed appreciably in the last 10 years. Comprehensive (or multidisciplinary) pain recovery programs consist of providers from multiple backgrounds that treat pain on an individual level through a combination of approaches including physical therapy, emotional and spiritual support, cognitive behavioral therapy, and non-opioid pharmacotherapies. Because there is a dynamic interplay between a given chronic pain patient and multiple providers, comprehensive pain programs are not as "standardized" as other medical treatments because they are meant to meet the individual needs of each patient and their specific pain diagnoses Methods: Review of the literature.

RESULTS

There is evidence that comprehensive pain treatment can reduce pain severity and improve functioning; comprehensive pain treatment can be used to treat those with post-surgical pain, thus preventing the onset of non-medical opioid use and opioid use disorder, and in persons with chronic pain who are on long-term opioid therapy, as a method to reduce or eliminate opioid medication use. Comprehensive pain recovery programs were abundant for a period from the 1960s through the 1980s, but for a variety of reasons, they became financially unsustainable as the national reimbursement environment evolved.

CONCLUSIONS

In the context of the protracted and deadly opioid crisis, revitalizing and expanding comprehensive pain treatment should be considered as a frontline approach to treat chronic pain.

Beneficial Effects of Opioid Rotation to Buprenorphine/Naloxone on Opioid Misuse, Craving, Mental Health, and Pain Control in Chronic Non-Cancer Pain Patients with Opioid Use Disorder

Patients with chronic non-cancer pain (CNCP) often use opioids for long periods of time. This may lead to opioid use disorder (OUD) and psychiatric symptoms: mainly depression and anxiety. The current study investigated the effect of buprenorphine/naloxone (BuNa) rotation on opioid misuse, craving, psychiatric symptoms and pain in patients with CNCP and OUD. Forty-three participants with CNCP and OUD were converted from a full mu-receptor agonist opioid (mean morphine equivalent dose: 328.3 mg) to BuNa, in an inpatient setting. Opioid misuse, craving, co-occurring psychiatric symptoms, and pain perception were determined at baseline and after a two-month follow-up, using the following self-report questionnaires: Current Opioid Misuse Measurement (COMM), Visual Analog Scale (VAS-craving and VAS-pain) and Depression, Anxiety and Stress Scale (DASS), respectively. VAS-craving and VAS-pain were also determined immediately after conversion. A total of 37 participants completed the protocol. The mean COMM decreased from 17.1 to 6.7 (F = 36.5; p < 0.000), the mean VAS-craving decreased from 39.3 to 5.3 (−86.6%; F = 26.5, p < 0.000), the mean DASS decreased from 12.1 to 6.6 (F = 56.3, p < 0.000), and the mean VAS-pain decreased from 51.3 to 37.2 (−27.4%, F = 3.3; p = 0.043). Rotation to BuNa in patients with CNCP and OUD was accompanied by reductions in (i) opioid misuse, (ii) opioid craving, (iii) the severity of co-occurring psychiatric symptoms, and (iv) self-reported pain. BuNa as opioid agonist treatment may therefore be a beneficial strategy in CNCP patients with OUD. The limited sample size and the observational nature of this study underline the need for the replication of the current findings in large-scale, controlled studies.

Predictors of engagement in an internet-based cognitive behavioral therapy program for veterans with chronic low back pain

Internet-based interventions for chronic pain have demonstrated efficacy and may address access barriers to care. Participant characteristics have been shown to affect engagement with these programs; however, limited information is available about the relationship between participant characteristics and engagement with internet-based programs for self-management of chronic pain. The current study examined relationships between demographic and clinical characteristics and engagement with the Pain EASE program, a self-directed, internet-based cognitive behavioral therapy intervention for veterans with chronic low back pain (cLBP). Veterans with cLBP were enrolled in a 10 week trial of the Pain EASE program. Engagement measures included the number of logins, access to coping skill modules, and completed study staff-initiated weekly check-in calls. Regression analyses were conducted to identify significant predictors of engagement from hypothesized predictors (e.g., race/ethnicity, age, depressive symptom severity, and pain interference). Participants (N = 58) were 93% male, 60.3% identified as White, and had a mean age of 54.5 years. Participants logged into the program a median of 3.5 times, accessed a median of 2 skill modules, and attended a median of 6 check-in calls. Quantile regression revealed that, at the 50th percentile, non-White-identified participants accessed fewer modules than White-identified participants (p = .019). Increased age was associated with increased module use (p = .001). No clinical characteristics were significantly associated with engagement measures. White-identified race/ethnicity and increased age were associated with greater engagement with the Pain EASE program. Results highlight the importance of defining and increasing engagement in internet-delivered pain care.

Complementary treatment comparison for chronic pain management: A randomized longitudinal study

Background

In chronic pain, it seems that the effect of cognitive-behavioral therapy (CBT) is boosted when it is combined with hypnosis. The aim of this study was to assess the efficacy of self-hypnosis combined with self-care (i.e., a type of CBT) compared to music/self-care, self-care and psychoeducation/CBT and to evaluate their long-term effects.

Methods

An open label randomized clinical trial enrolled patients with chronic pain and was carried out at the University Hospital of Liège (Belgium). Patients were randomized into four groups: self-hypnosis/self-care, music/self-care, self-care, psychoeducation/CBT (7 monthly sessions of 2 hours). Two follow-up sessions were delivered at 6- and 12-month. Levels of pain, fatigue intensity, anxiety, depression, insomnia severity, disability, health locus of control, mental and physical quality of life and attitudes (control, disability, harm, emotion, medical cure, medication, solicitude) towards pain were assessed before and after the treatments, and at follow-up.

Results

203 patients were randomized: 52 in self-hypnosis/self-care, 59 in music/self-care, 47 in self-care, and 45 in psychoeducation/CBT. No group effect was found. A significant time effect was showed. Directly after the treatment, all groups decreased in pain attitudes and physical quality of life. Perceived control increased. At 6-month, all patients kept their levels of physical quality of life and perceived control, and showed decrease in pain intensity, harm, emotion and medical cure. At 12-month, scores that had change previously remained ameliorated, a decrease in insomnia severity and an increase in internal locus of control were observed.

Conclusions

The present findings are encouraging as they display long-term beneficial effects of complementary biopsychosocial-based treatments in chronic pain. It seems that patients continued to apply the learnt strategies as improvements were observed one year after the treatments had ended.

Health-related quality of life deviations from population norms in patients with lumbar radiculopathy: associations with pain, pain cognitions, and endogenous nociceptive modulation

PURPOSE

The primary goal of this study was to compare the health-related quality of life (HRQoL) of people with lumbar radiculopathy to age- and sex-adjusted population norms. Additionally, it aimed to explore the associations between the HRQoL difference scores and measures related to pain cognitions, pain intensity, and endogenous nociceptive modulation.

METHODS

Using answers from the Short Form 36-item Health Survey and UK population norms, SF-6D difference scores were calculated. A one-sample t test was used to assess the SF-6D difference scores. Univariate and multivariate regression analyses were used to assess the associations between SF-6D difference scores and pain intensity [Visual Analogue Scale (VAS) for back and leg pain], pain cognitions [Pain Catastrophizing Scale (PCS), Tampa Scale for Kinesiophobia (TSK), Pain Vigilance and Awareness Questionnaire (PVAQ)], and correlates for endogenous nociceptive modulation using quantitative sensory testing.

RESULTS

One hundred and twenty people with lumbar radiculopathy scheduled for surgery were included in this study. The mean SF-6D difference score of - 0.26 [SD = 0.09] was found to be significantly less than 0 [95%CI: - 0.27 to - 0.24]. Univariate analyses showed a significant influence from PCS, TSK, and PVAQ on the SF-6D difference scores. The final multivariate regression model included PCS and PVAQ, with only PCS maintaining a statistically significant regression coefficient [b = - 0.002; 95% CI: - 0.004 to - 0.001].

CONCLUSION

People diagnosed with lumbar radiculopathy report significantly lower HRQoL scores when compared with age- and sex-adjusted UK norm values. Even though all examined pain cognitions were found to have a significant association, pain catastrophizing showed the most significant relation to the SF-6D difference scores.

The association between chronic pain conditions and subclinical and clinical anxiety among community-dwelling older adults consulting in primary care

OBJECTIVE

To examine associations between chronic pain conditions, pain level, and subclinical/clinical anxiety in community-dwelling older adults.

DESIGN

Cross-sectional associations were analyzed using multinomial logistic regression to compare the odds of having subclinical/clinical anxiety by painful condition and pain level, controlling for confounders.

SETTING

Participants were recruited in primary care waiting rooms to take part in the first wave of the Étude sur la Santé des Aînés (ESA)-Services study.

SUBJECTS

1608 older adults aged 65+.

METHODS

Clinical anxiety was assessed using DSM-IV criteria. Subclinical anxiety was considered present when participants endorsed symptoms of anxiety but did not fulfill clinical diagnostic criteria for an anxiety disorder. Painful chronic conditions included arthritis, musculoskeletal conditions, gastrointestinal problems, and headaches/migraines. Presence of painful conditions was assessed using combined self-report and health administrative data sources. Pain level was self-reported on an ordinal scale. Physical comorbidities were identified from ICD-9/10 diagnostic codes and depression was evaluated based on the DSM-IV.

RESULTS

Sixty-six percent of home-living older adults suffer from a chronic pain condition. Older adults with clinical anxiety are more likely to experience musculoskeletal pain, gastrointestinal problems, headaches/migraines, and higher pain levels compared to those with no anxiety. Also, those with ≥3 painful conditions are at greater risk for subclinical and clinical anxiety compared to those with no painful condition.

CONCLUSIONS

These results emphasize the need for assessing anxiety symptoms in older adults with chronic pain conditions. Comprehensive management of comorbid chronic pain and psychopathology might help reduce the burden for patients and the healthcare system.

Psychogenic non-epileptic seizures in children

Psychogenic Non-Epileptic Seizures (PNES) are a relatively common condition in children. While their clinical presentation resembles epileptic seizures, the underlying cause for PNES involves a multitude of bio-psychosocial factors. Patients may be misdiagnosed with epilepsy and subjected to unnecessary treatments, often delaying the diagnosis for years. A strong understanding of its symptomatology is essential for diagnosis of PNES. Successful management depends on effective teamwork that involves the neurologist as well as mental health professionals. This paper reviews the various aspects of PNES in children with emphasis on the clinical presentation, diagnosis as well as the underlying psychological basis and treatment.

Modulation of mRNA expression of IL-6andmTORC1 and efficacy and feasibility of an integrated approach encompassing cognitive behavioral therapy along with Pregabalin for management of neuropathic pain in Postherpetic Neuralgia: A Pilot Study

OBJECTIVE

This study was designed to explore the efficacy and feasibility of cognitive behavioural therapy(CBT) along with pregabalin and compare it with pregabalin monotherapy for the management of neuropathic pain in post-herpetic neuralgia (PHN) patients and to explore the modulation of mRNA expression of interleukin (IL)-6 and mammalian target of rapamycin-1 (mTORC1) genes in these patients.

DESIGN

Randomized controlled pilot study.

METHODS

The patients aged >18 years of age with an established diagnosis of PHN with evident allodynia and hyperalgesia who had pain for at least 3 months after healing of rash with pain intensity ≥4/10 on NRS-Pain Scale were enrolled. The trial was registered with the Clinical Trials Registry-India (CTRI/2019/03/018014). A detailed baseline assessment regarding type and duration of pain and disability using pain-relevant self-report questionnaires was done. Two ml venous blood samples were collected for gene expression studies at base line and at end of 12 weeks of treatment. Patients were randomized into one of the two groups. Group PR received pregabalin and Group CP received CBT along with pregabalin. The pain intensity was measured using numeric rating scale (NRS)-Pain scale, neuropathic component of the pain by using Neuropathic Pain Symptom Inventory (NPSI) and Pain Detect Questionnaire (PDQ), sleep interference by NRS-Sleep, pain-related catastrophic thoughts by using Pain Catastrophizing Scale (PCS), depression and quality of life using Beck Depression Inventory-II (BDI-II) and Short Form-12 (SF-12), respectively. The research funding was supported by the intramural grant from the institution.

RESULTS

A total of 40 patients with 20 in each group were included. Following integrated approach encompassing CBT and Pregabalin, group CP had significant downregulation of mRNA expression of IL-6; however, no such correlation was observed with mTOR expression. A significant decline in the intensity of pain, NPSI scoring for burning, allodynia, and pain-related catastrophizing were observed; also a significant improvement in depressive symptoms and quality of life were observed with the use of CBT.

CONCLUSIONS

A significant downregulation of mRNA expression of IL-6 was observed; however, no significant correlation was observed between NRS pain score and ΔCt values of mRNA expression of both mTORC1 gene and IL-6 gene at baseline and at the end of 12th week. In addition, we note a significant decrease in pain intensity, depressive symptoms, and pain-related catastrophizing while improving QOL was observed with the use of CBT as a clinical adjunct along with pregabalin in PHN patients.

Activity Patterns and Functioning. A Contextual-Functional Approach to Pain Catastrophizing in Women with Fibromyalgia

Background: The psychological flexibility model states that activity patterns are not deemed to be intrinsically functional or dysfunctional; it is considered that underlying factors, such as personal goals and contextual factors, are what will determine their effects on disability. Pain catastrophizing has frequently been associated with several important pain-related outcomes. Despite its recent conceptualization within affective–motivational approaches, its moderating role between activity patterns and dysfunction has not been analyzed. Methods: This study analyzes the moderating role of pain catastrophizing and its dimensions (Pain Catastrophizing Scale) between activity patterns (Activity Patterns Scale) and disease impact (Fibromyalgia Impact Questionnaire—Revised) in 491 women with fibromyalgia. Results: Activity avoidance (p < 0.001), excessive persistence (p < 0.001) and pacing (p < 0.01) patterns were positively associated with fibromyalgia impact. Helplessness shows a moderating role between pain avoidance (B = 0.100, t =2.30, p = 0.021, [0.01, 0.18]), excessive persistence (B = −0.09, t = −2.24, p = 0.02, [−0.18, −0.01]), pain persistence (B = −0.10, t = −2.04, p = 0.04, [−0.19, −0.004]) and functioning. Conclusion: Helplessness (within pain catastrophizing) is a relevant variable within psychological flexibility models applied to activity patterns. Specifically, pain avoidance is especially dysfunctional in patients with high helplessness. To improve excessive persistence and pain persistence, it is necessary to reduce helplessness before regulating activity patterns.

The Role of Pain-Related Cognitions in the Relationship Between Pain Severity, Depression, and Pain Interference in a Sample of Primary Care Patients with Both Chronic Pain and Depression

OBJECTIVE

The aims of this study were twofold: 1) to better understand the associations between pain-related cognitions and pain severity, and psychological and physical function, and 2) to determine the extent to which these cognitions function as mediators in the association between pain severity and depression in a sample of primary care adult patients with chronic pain and depression.

DESIGN

Cross-sectional design.

METHODS

Three hundred twenty-eight patients with both depression and chronic pain from primary care centers responded to measures of pain severity, pain interference, depression severity, and pain-related cognitions (including measures of catastrophizing and other pain-related beliefs). We performed three hierarchical regression analyses and two multiple regression analyses.

RESULTS

The helplessness domain of pain catastrophizing was positively associated with pain severity, depression severity, and pain interference and mediated the relationship between depression and pain severity and vice versa. Beliefs about disability showed a positive association with pain severity, pain interference, and depression severity, and also mediated the relationship between pain severity and depression. Believing in a medical cure was positively associated with pain interference and negatively associated with depression; emotion beliefs were positively associated with pain severity.

CONCLUSIONS

These findings provide important new information about the associations between several pain-related cognitions and pain severity, depression, and pain interference and the potential mediating roles that these cognitions play in the associations between pain severity and depression in patients with both chronic pain and depression in the primary care setting.
