Primary care management of non-specific low back pain: key messages from recent clinical guidelines

O'Connor D, Gelber N, Bourne A, G. Maher C, Buchbinder R. Australian General Practitioners' Use of Diagnostic Lumbar Spine Imaging for Patients With Acute Low Back Pain: A Qualitative Study

BACKGROUND

General practitioners (GPs) use of imaging for acute low back pain (LBP) is above guideline recommendations, and the reasons for this remain under-researched. We examined the perspectives, expectations and information needs of Australian GPs requesting lumbar spine diagnostic imaging for patients presenting with acute LBP.

METHODS

We completed semi-structured interviews with 12 GPs practising in Victoria, Australia. Transcripts were thematically analysed, and themes compared according to whether or not GPs reported they regularly requested imaging for LBP.

RESULTS

We identified four themes. (1) Besides responding to 'red flags', GPs' experiences of uncovering unexpected but serious findings on imaging for LBP as well as perceived external pressures motivated their defensive imaging practices. (2) While most were reluctant to request imaging for LBP, once requested, GPs escalated through imaging modalities and focused on the diagnostic benefit of their findings. (3) GPs supported the inclusion of epidemiological data on imaging reports, but (4) largely opposed imaging reports being written in plain language, believing reports to be clinician-to-clinician communications that patients would misunderstand. All GPs were aware of the limited utility of imaging for diagnosing LBP, and themes were similar between GPs who regularly requested imaging and those who did not. Factors other than knowledge of imaging efficacy for LBP seemed to play an important role in imaging requests.

CONCLUSIONS

Our study identified key drivers of imaging use for LBP in primary care. The findings underscore that interventions targeting GPs addressing the overuse of imaging for LBP should transcend knowledge deficit models.

Dutch translation, cross-cultural adaptation, validation, and reliability of the Back Pain Attitudes Questionnaire (Back-PAQ)

PURPOSE

To translate and cross-culturally adapt the Back Pain Attitudes Questionnaire (Back-PAQ) to Dutch for the Belgian and Dutch populations, and to investigate its measurement properties in the general population and physiotherapists.

METHODS

The adaptation followed established guidelines. Content validity, internal consistency, test-retest reliability (intraclass correlation coefficient), floor and ceiling effects, minimal detectable change (MDC), construct validity, and structural validity were assessed in physiotherapists and the general population. The modified Fear-Avoidance Beliefs Questionnaire (mFABQ) investigated the Back-PAQ's convergent validity, and Confirmatory Factor Analysis evaluated structural validity. Discriminant validity was assessed between physiotherapists and the general population.

RESULTS

Two hundred and sixty participants (mean age: 29 ± 13.3) completed the initial survey and 147 completed the test-retest survey. All Back-PAQ versions (34-item, 20-item, and 10-item) demonstrated good internal consistency, good to excellent test-retest reliability. Moderate correlations with the mFABQ (p < 0.001) and adequate discriminant validity between physiotherapists and the general population supported robust construct validity. The Back-PAQ 10 exhibited a good model fit and enables meaningful sub-score comparisons.

CONCLUSIONS

This collaboration produced a validated Dutch Back-PAQ suitable for use in both the Netherlands and Belgium. All versions demonstrated robust measurement properties, supporting their use in clinical and research settings assessing unhelpful beliefs in back pain management.

State-of-the-Art Personalized Therapy Approaches for Chronic Non-Specific Low Back Pain: Understanding the Mechanisms and Drivers

Chronic non-specific low back pain (CNSLBP) is a debilitating condition that affects millions of people worldwide, significantly impacting quality of life and imposing a substantial socioeconomic burden. Traditional treatment approaches often rely on a one-size-fits-all strategy, failing to account for individual variations in pathophysiological mechanisms, drivers, and the principles of personalized medicine. Furthermore, an overemphasis on biomechanical findings from imaging may lead to ineffective interventions and unnecessary surgical procedures, obscuring other important factors that contribute to pain perception. While highlighting the limitations of universal treatment approaches, in this review we present a practical clinical approach aimed at elucidating the main pathophysiological mechanisms and various factors underlying the development and maintenance of CNSLBP in order to create a personalized treatment program. In conclusion, this review underscores the need for personalized therapeutic strategies that take into account the unique characteristics of each patient, recognizing the complex interaction of biological, psychological, social, and other factors that contribute to the development of individual pain. By combining a comprehensive understanding of the complexities of this condition, we aim to improve clinical outcomes and provide information on the development of effective personalized treatment algorithms, particularly in the field of neurological practice.

Understanding patients' perceptions of uncomplicated low back pain: a theory-informed qualitative study using the Common-Sense Self-Regulation Model

BACKGROUND

Uncomplicated low-back pain (LBP), referring to LBP without symptoms that suggest an underlying medical or surgical cause, is a common and challenging problem for patients and primary healthcare providers. Multiple guidelines discourage the use of diagnostic imaging for uncomplicated LBP due to cost and lack of benefit; despite this, diagnostic imaging remains overused in this condition. Study of primary healthcare providers suggests that patient expectations contribute to imaging for uncomplicated LBP. Dedicated study of patient understanding and experiences of uncomplicated LBP is necessary to design interventions to reduce unnecessary diagnostic imaging.

METHODS

In this theory-guided qualitative study, people with uncomplicated LBP were recruited for a semi-structured interview. The Common Sense - Self-Regulation Model (CS-SRM), a framework that explores the relationship between a patient's perceptions, beliefs, and behaviors around their illness and the outcome of their illness, was selected to direct development of the interview guide and analysis. Higher-level themes were created to list patient-related drivers of unnecessary diagnostic imaging for uncomplicated LBP.

RESULTS

Thirteen participants (7 female) had experienced uncomplicated LBP for a median of 5 years (IQR 2-20 years; range 1 to 30 years). Framework analysis based on the CS-SRM suggested that most participants understood their uncomplicated LBP as a permanent part of their lives, though some felt that the pain could be controlled or prevented. Participants shared a range of coping mechanisms, including social support, medication, and exercises. For most participants, uncomplicated LBP negatively affected their lives emotional wellbeing characterized by a sense of loss from missing life events due to pain. Nearly all participants had visited their primary care physician (n = 11) and most underwent diagnostic imaging (n = 8); however, participants generally reported that they had not requested diagnostic imaging (n = 8). Several participants reported that they wanted validation and symptom-management advice from their physician rather than diagnostic tests.

CONCLUSIONS

In contrast to other studies, we report that most patients with uncomplicated LBP in our setting did not request diagnostic imaging. Patient-facing interventions to address unnecessary diagnostic imaging for uncomplicated LBP may be more effective if they address illness conceptions identified in this study; for example, interventions should convey empathy by acknowledging patient worries, validating suffering, describing potential causes or triggers, addressing self-management strategies, and describing the natural history of uncomplicated LBP.

Patients' Experiences Participating Within an Interdisciplinary Primary Care Program for Low Back Pain

A common recommendation to improve the management of low back pain (LBP) is the use of interdisciplinary teams. However, many challenges remain in establishing interdisciplinary care, particularly in community-based primary care settings. This study explored patients' experiences with interdisciplinary care for LBP using an applied phenomenological research approach. Semistructured open-ended interviews were conducted with fifteen adults enrolled in a 6-month interdisciplinary LBP program within an integrated care network. The analysis included detailed descriptions of participants' experiences and interpretations by the researchers of the main themes: (i) challenging start-"It's intimidating," (ii) desire for flexibility-"I didn't need as much," (iii) better collaboration-"They are all together," (iv) grasping the pain issue-"They helped," (v) care was responsive to needs and experience-"Always centered on me, not general," (vi) meanings of recovery-"I'm able to function." Participants viewed the interdisciplinary LBP program as the culmination of a long journey toward recovery. The findings identified as important to patients contribute to our understanding of how to optimize patient-centered care for individuals living with chronic pain.

Integrative Treatment Strategies for Chronic Back Pain: A Literature Review with Clinical Recommendations

PROBLEM

Chronic back pain (CBP) is a major cause of disability, contributing significantly to healthcare costs and primary care visits. Pharmacotherapy alone is insufficient in managing CBP. Integrated behavioral health interventions that include psychoeducation are critical for a more holistic, sustainable treatment of CBP.

OBJECTIVES

This review explores CBP treatments that includes psychoeducation as part of patient care.

METHODS

In the Fall of 2024, the first author searched Google Scholar, PubMed, and Scopus using search terms related to chronic back pain and integrated behavioral interventions to increase patients' self-efficacy to manage CBP. The team included articles in the review that were published more recently and seminal articles in the field of managing CBP.

RESULTS

Given the complex biopsychosocial factors influencing CBP, and the individualized nature of each patient's pain experience, patient psychoeducation should include a multimodal approach, which may include cognitive behavioral strategies to address pain, pain neuroscience education, and education related to lifestyle behaviors such as physical activity, sleep, nutrition, and stress management. Patient education and behavioral interventions integrated within primary care can significantly improve patient engagement and self-reported improvements in pain intensity, functionality, and quality of life.

CONCLUSION

Psychoeducation is foundational for integrative programs aimed at managing CBP.

Graded activity for chronic low back pain

OBJECTIVES

This is a protocol for a Cochrane Review (intervention). The objectives are as follows: To assess the benefits and harms of graded activity compared to placebo, sham, or no treatment for pain and function in adults with chronic non-specific low back pain.

"Gleaning a lot from the history and physical exam," and "reasonably confident without imaging": a qualitative study of primary care clinicians' management of patients with low back pain

BACKGROUND

Routine seeking of imaging for patients with low back pain is not concordant with the evidence-based recommendation that imaging is rarely of diagnostic value. Inappropriate imaging is a waste of resources and can lead to undesirable downstream effects for individuals and health systems. To develop effective strategies to reduce unwarranted referrals for imaging in primary care, we must understand the drivers for, and barriers to, guideline-adherent practice. We explored clinicians' views to identify the dominant influences on clinicians as they choose to pursue, or avoid, imaging for their patients with low back pain.

METHODS

We interviewed a purposeful sample of 47 primary care clinicians (14 physiotherapists, 18 chiropractors, 15 physicians) throughout Ontario, Canada, with a guide based on the Theoretical Domains Framework (TDF). We investigated clinicians' views about their use of imaging in the management of low back pain. Interviews were recorded and transcribed verbatim. We analysed transcripts, then identified themes within TDF domains.

RESULTS

Most clinicians reported that, for most clinical encounters, they adhered to guideline recommendations about imaging. Many clinicians across disciplines expressed the following themes: (1) imaging may result in an incidental finding or otherwise cause harm to patients, and drive up health system costs (TDF domain Beliefs about consequences); (2) clinicians were confident in their abilities to diagnose, to explain to patients the rationale for not recommending imaging, and to respond to their needs (domains Beliefs about capabilities; Skills). Many clinicians identified that patients occasionally want the validation that imaging provides (domain Social influences). Some clinicians described the value of imaging to corroborate a diagnosis (domain Beliefs about consequences).

CONCLUSIONS

This study is the first to examine influences on imaging behaviours of a large interprofessional sample of primary care clinicians in Canada. Even among knowledgeable, skilled, confident clinicians who reported mostly adhering to guideline recommendations, there are potential influences on deviating from guideline-adherent care.

The prognostic reasoning by physiotherapists of musculoskeletal disorders: A phenomenological exploratory study

QUESTION(S)

What are the prognostic reasoning practices of physiotherapists towards musculoskeletal disorders?

DESIGN

Exploratory phenomenological study.

PARTICIPANTS

15 physiotherapists who currently treat musculoskeletal disorders.

DATE ANALYSIS

Semi-structured interviews were implemented to collect data which was analysed using an inductive coding and thematic analysis approach.

RESULTS

Three themes were identified. First, how physiotherapists considered prognosis within clinical practice. Whilst prognosis is an important consideration, in some circumstances it either may not be considered or is implied. Second, how physiotherapists determine prognosis for musculoskeletal disorders. Several factors shaped the ability of physiotherapists to determine prognosis including how they determine prognosis, and the barriers and facilitators towards determining prognosis. Finally, how physiotherapists discuss prognosis with individuals who have a musculoskeletal disorder. These discussions were shaped by the prognostic information provided, as well as the barriers and facilitators towards discussing prognosis.

CONCLUSION

The prognostic reasoning of physiotherapists appears to be influenced initially by whether they consider it or not. It is then shaped by both barriers and facilitators towards determining and discussing prognosis. Facilitators for this prognostic reasoning process appear to be aligned with the biomedical model of health, whilst barriers more aligned with psychosocial factors. To improve prognostic reasoning, physiotherapists should continue to strive to conceptualize prognosis within a biopsychosocial framework. Doing so will improve the ability of physiotherapists to prognosticate, which will subsequently improve outcomes associated with musculoskeletal disorders.

Unhelpful Information About Low Back and Neck Pain on Physiotherapist's Websites

BACKGROUND

The internet is increasingly used as a primary source of information for patients with musculoskeletal pain. Private physiotherapy practices provide informative content on low back pain (LBP) and neck pain (NP) on their websites, but the extent to which this information is biopsychosocial, guidelines-consistent, and fear-inducing is unknown. The aim of this study was to analyse the information on websites of private physiotherapy practices in the Netherlands about LBP and NP regarding consistency with the guidelines and the biopsychosocial model and to explore the use of fear-inducing language.

METHODS

The content of all existing Dutch private physiotherapy practice websites was examined in a cross sectional study design. Content analysis was based on predetermined criteria of the biopsychosocial model and evidence-based guidelines. Descriptive statistics were applied.

RESULTS

After removing duplicates and sites without information, 834 (10%) of 8707 websites remained. Information about LBP was found on 449 (54%) websites and 295 (35%) websites informed about NP. A majority of websites (LBP: n = 287, 64%; NP: n = 174, 59%) were biomedically oriented. Treatment advice was given 1855 times on n = 560 (67%) websites. Most of the recommended interventions were inconsistent with or not mentioned in the guidelines. Fear-inducing language was provided n = 1624 (69%) times.

CONCLUSIONS

The majority of the information on the Dutch private physiotherapy websites was biomedical and not in line with the current guidelines and fear-inducing.

SIGNIFICANCE

This study revealed that the majority of private physiotherapy practice websites that provide information on LBP and NP are inconsistent with the biopsychosocial model and current guidelines. This information has a negative impact on patients' knowledge, attitudes, beliefs, and expectations, potentially affecting treatment outcomes. Consequently, most physiotherapy practice websites are unreliable sources of information on LBP and NP for patients. There is an urgent need to implement strategies to make websites reliable and helpful sources of information.

The effectiveness of education for people with shoulder pain: A systematic review

OBJECTIVES

To investigate the effectiveness of education for people with shoulder pain.

DESIGN

Systematic review LITERATURE SEARCH: We searched several databases (e.g. MEDLINE, EMBASE, CENTRAL, CINAHL) and trial registries from inception to May 25, 2023.

STUDY SELECTION CRITERIA

Randomised controlled trials investigating any education for people with shoulder pain.

DATA SYNTHESIS

Pain and disability were primary outcomes. The Physiotherapy Evidence Database (PEDro) scale was used to assess methodological quality. Meta-analysis was not appropriate due to heterogeneity.

RESULTS

We included 14 trials (8 had high methodological quality). The one trial on rotator-cuff related shoulder pain did not assess pain or disability but found best practice education (vs. structure-focused education) increased reassurance and intentions to stay active. The one trial on adhesive capsulitis found daily reminders, encouragement, and education about exercise via text did not improve pain and disability compared to no education. For post-operative shoulder pain, two (of four) trials found education reduced some measure of pain, but none found an effect on disability or any other outcomes. For 'shoulder complaints' (i.e. mixed or unclear diagnosis), no trials found education was more effective than home exercise or no education for improving pain or disability.

CONLUSION

Some forms of education appear to improve reassurance, treatment intentions, perceived treatment needs, recovery expectations, and knowledge, but their effect on pain and disability is unclear. High-quality trials are needed to resolve uncertainty surrounding the benefit of education for shoulder pain, particularly rotator-cuff related shoulder pain and adhesive capsulitis.

Assessing the performance of AI chatbots in answering patients' common questions about low back pain

OBJECTIVES

The aim of this study was to assess the accuracy and readability of the answers generated by large language model (LLM)-chatbots to common patient questions about low back pain (LBP).

METHODS

This cross-sectional study analysed responses to 30 LBP-related questions, covering self-management, risk factors and treatment. The questions were developed by experienced clinicians and researchers and were piloted with a group of consumer representatives with lived experience of LBP. The inquiries were inputted in prompt form into ChatGPT 3.5, Bing, Bard (Gemini) and ChatGPT 4.0. Responses were evaluated in relation to their accuracy, readability and presence of disclaimers about health advice. The accuracy was assessed by comparing the recommendations generated with the main guidelines for LBP. The responses were analysed by two independent reviewers and classified as accurate, inaccurate or unclear. Readability was measured with the Flesch Reading Ease Score (FRES).

RESULTS

Out of 120 responses yielding 1069 recommendations, 55.8% were accurate, 42.1% inaccurate and 1.9% unclear. Treatment and self-management domains showed the highest accuracy while risk factors had the most inaccuracies. Overall, LLM-chatbots provided answers that were 'reasonably difficult' to read, with a mean (SD) FRES score of 50.94 (3.06). Disclaimer about health advice was present around 70%-100% of the responses produced.

CONCLUSIONS

The use of LLM-chatbots as tools for patient education and counselling in LBP shows promising but variable results. These chatbots generally provide moderately accurate recommendations. However, the accuracy may vary depending on the topic of each question. The reliability level of the answers was inadequate, potentially affecting the patient's ability to comprehend the information.

Tuina versus physiotherapy or a combination of both for the management of chronic nonspecific low back pain: A randomized controlled trial

OBJECTIVE

To rigorously evaluate the short-term and long-term effectiveness of Tuina (TN), alone and in combination with physiotherapy (PT), for Chronic nonspecific low back pain (CNLBP) through a comprehensive, high-quality clinical trial.

METHODS

This randomized, single-blind trial was conducted from September 2020 to July 2023, involving 204 CNLBP patients from the First Affiliated Hospital of Jinan University. Participants underwent a baseline assessment, 6 treatment sessions over 8 weeks, a post-treatment evaluation in the 9th week, and a 20-week follow-up. Participants were randomly assigned to TN, PT, or a combination of TN and PT (TP) groups. Each treatment involved 6 sessions with a minimum 7-day interval, each lasting 30 minutes. Primary outcome was the change in Visual Analog Scale (VAS) for pain. Secondary outcomes included the Oswestry Disability Index (ODI), 36-Item Short Form Health Survey (SF-36), Range of Motion (ROM) of the spine, Traditional Chinese Medicine Syndrome Scale (TCMSS), and adverse events (AE).

RESULTS

Among the 204 participants, 67.16 % were female, and 88.73 % completed the 20-week follow-up. All groups showed significant reductions in VAS scores post-treatment and at follow-up. Secondary outcomes improved significantly, with notable decreases in ODI and TCMSS scores. Pairwise comparisons within groups indicated statistical significance, particularly in ODI scores, with clinical relevance. No significant differences were found between the groups. ROM and SF-36 showed statistical but not clinical significance. Only one AE (0.49 %) was reported, with no severe incidents.

CONCLUSION

All treatment groups, including TN, TP, and PT, demonstrated significant reductions in VAS scores for CNLBP patients, with effects lasting up to 20 weeks. While TN and TP showed substantial improvements in secondary outcomes, particularly in ODI scores, no significant differences were found between the groups. These findings suggest that all treatments can be effective for managing CNLBP, supporting clinical practitioners in selecting appropriate interventions for patients, especially for those unable to engage in active exercises, utilizing passive movements like TN to enhance health outcomes.

Research hotspots and frontiers in non-specific low back pain: a bibliometric analysis

Background

Extensive research has been conducted worldwide on non-specific low back pain (NSLBP), some researchers published a bibliometric analysis of NSLBP in 2020, but there have been no supplements or updates since then. Therefore, this study aimed to analyze the research hotspots and frontiers in NSLBP over the last decade.

Methods

Primary sources on NSLBP were obtained from the Web of Science Core Collection database from 2014 to 2023. CiteSpace V6.2. R7 (64-bit) and VOSviewer 1.6.19 software were used to analyze the number and centrality of journals, countries, institutions, authors, references, and keywords, and the functions of co-occurrence and clustering were applied to draw a visual knowledge map.

Results

In the past decade, the annual publication volume of studies on NSLBP has shown an overall upward trend year by year, with obvious temporal stages and great development potential. In total, 2,103 articles contained six types of literature, with the highest proportion being original research articles (1,633 articles, 77.65%), published in 200 journals. BMC Musculoskeletal Discourses (90 articles, 4.28%) had the highest number of publications, and the British Medical Journal had the highest impact factor (105.7). Furthermore, the United States of America (329 articles, 15.64%) had the highest publication volume, the University of Sydney (139 articles, 6.61%) was the research institution with the highest production, Maher, Chris G (36 articles, 1.71%) was the author with the most published articles, and Hoy, D (571 articles, 27.15%) was the most frequently cited author. The most cited of articles is "Non-specific low back pain" published in the LANCET, with 1,256 citations.

Conclusion

This article summarizes the current research status of NSLBP and predicts future research hotspots and frontiers. In recent years, adolescents have become a high-risk group for NSLBP. Pain neuroscience education, motor control, spinal manipulative therapy, and acupuncture are effective means to treat NSLBP. Biomechanics and trunk muscles as entry points are effective ideas for the treatment of NSLBP pain. Furthermore, anxiety, neck pain, non-specific musculoskeletal pain, fibromyalgia, and musculoskeletal disorders are diseases that are closely related to NSLBP. In the future, attention should be paid to the design of research plans, increasing the research intensity of randomized controlled trials, strengthening follow-up, and the timely updating of guidelines, which will result in higher quality and high-level scientific evidence for research on NSLBP.

Effectiveness of a physiotherapy self-management programme for adult patients with chronic non-specific low back pain in low- and middle-income countries: protocol for a systematic review and meta-analysis

INTRODUCTION

Chronic non-specific low back pain (CNLBP) is among the most common musculoskeletal system conditions reported worldwide; however, few studies are available from low- and middle-income countries (LMICs). Self-management is a set of tasks performed by the patient aiming at managing their symptoms and interference in activities, mood and relationships due to pain. A physiotherapy-guided self-management programme (SMP) following a biopsychosocial approach has been reported as effective and affordable in the management of CNLBP in high-income countries. The objective of this systematic review is to determine the overall effectiveness of SMPs for adults with CNLBP in LMICs.

METHODS AND ANALYSIS

In this systematic review, the Preferred Reporting Items for Systematic Reviews and Meta-Analyses-Protocol (PRISMA-P) guidelines will be followed. A three-step search strategy will be used to search the electronic databases (PubMed, MEDLINE, SPORTDiscus, Scopus and CINAHL, Academic Search Complete and PEDro) for randomised controlled trials assessing the effectiveness of physiotherapy-guided self-management for CNLBP among adult participants in LMICs. The processes of screening search results for eligible studies, extracting data from included studies and appraising will be done independently by at least two review authors. Random effects meta-analysis will be used to synthesise results and heterogeneity will be assessed using the I2 test statistic and χ2 test.

ETHICS AND DISSEMINATION

Ethics clearance was obtained for the broader PhD study on the development of a physiotherapy-guided SMP for adult people with CNLBP in Limpopo Province, South Africa. The results of the manuscript for this protocol will be published in peer-reviewed journals and also presented at conferences, symposia, and congresses.

Impact of Prescription Medicines on Work-Related Outcomes in Workers with Musculoskeletal Disorders or Injuries: A Systematic Scoping Review

PURPOSE

Medicines are often prescribed to workers with musculoskeletal disorders (MSDs) and injuries to relieve pain and facilitate their recovery and return to work. However, there is a growing concern that prescription medicines may have adverse effects on work function. This scoping review aimed to summarize the existing empirical evidence on prescription medicine use by workers with MSD or injury and its relationship with work-related outcomes.

METHODS

We identified studies through structured searching of MEDLINE, EMBASE, PsycINFO, CINAHL Plus, Scopus, Web of Science and Cochrane library databases, and via searching of dissertations, theses, and grey literature databases. Studies that examined the association between prescription medicine and work-related outcomes in working age people with injury or MSDs, and were published in English after the year 2000 were eligible.

RESULTS

From the 4884 records identified, 65 studies were included for review. Back disorders and opioids were the most commonly studied musculoskeletal conditions and prescription medicines, respectively. Most studies showed a negative relationship between prescription medicines and work outcomes. Opioids, psychotropics and their combination were the most common medicines associated with adverse work outcomes. Opioid prescriptions with early initiation, long-term use, strong and/or high dose and extended pre- and post-operative use in workers' compensation setting were consistently associated with adverse work function. We found emerging but inconsistent evidence that skeletal muscle relaxants and non-steroidal anti-inflammatory drugs were associated with unfavorable work outcomes.

CONCLUSION

Opioids and other prescription medicines might be associated with adverse work outcomes. However, the evidence is conflicting and there were relatively fewer studies on non-opioid medicines. Further studies with more robust design are required to enable more definitive exploration of causal relationships and settle inconsistent evidence.

Moderators of treatment effect of non-steroidal anti-inflammatory drugs for patients with (sub) acute low back pain: Protocol for a systematic review with individual participant data meta-analysis

A Cochrane review found that non-steroidal anti-inflammatory drugs (NSAIDs) are slightly more effective than placebo on acute and subacute low back pain (LBP) outcomes (pain intensity, disability, and global improvement). Our objectives are: (1) to assess the overall treatment effect of NSAIDs in adults with acute and subacute LBP; (2) to identify the moderation of baseline patients' characteristics on treatment effect. We will conduct a systematic search of RCTs on effectiveness of NSAIDs compared with placebo in adults with non-chronic LBP in Medline ALL, Embase, Cochrane Central Register of Controlled Trials*. We will screen the records after January 2020, and include eligible RCTs before January 2020 screened by the Cochrane review mentioned above. Our primary outcomes are pain intensity, disability, and health-related quality of life, secondary outcomes are adverse events. Our IPD dataset will consist of the information on each eligible trial characteristics and included variables according to a predefined coding scheme. We will assess risk-of-bias of included RCTs with the Cochrane Risk Of Bias (RoB)-2 assessment tool. We will perform power calculations with closed-form solutions and prioritize a one-stage approach for IPD-MA. For reporting the results, we will adhere to the PRISMA-IPD statement.

Patient experiences of referral practices and primary care physiotherapy for chronic nonspecific low back pain

BACKGROUND

Low back pain (LBP) clinical practice guidelines recommend referral for patients with persistent LBP however discordance persists between recommended care and implementation in practice. Understanding patient experiences of referral practices and physiotherapy care could be important for optimizing LBP management in primary care settings.

PURPOSE

This study explored referral experiences of people with nonspecific LBP in Australian primary care and their knowledge and experience of physiotherapy.

METHODS

An interpretive descriptive qualitative framework was used with 17 participants interviewed from community-based physiotherapy practices.

RESULTS

Four themes described the participants' experiences of referrals in primary care settings: 1) Referral practices ranged from formal to informal to non-existent; 2) Fragmented inter-and intra-professional LBP care management; 3) Patient perceived differences in the roles of physiotherapists and specialist physiotherapists; and 4) Patient nominated barriers and facilitators to optimal referral practices.

CONCLUSION

Physiotherapists support people with LBP to improve strength and function, whereas the specialist physiotherapist's role was seen as more holistic. Referral pathways that align to clinical guideline recommendations for non-surgical management and treatment remain underdeveloped. Improved referral pathways to clinicians such as physiotherapists with additional credentialed skills and competence in musculoskeletal care could improve people's experiences of care and health outcomes.

Implementation of an integrated primary care prevention and management program for chronic low back pain (LBP): patient-reported outcomes and predictors of pain interference after six months

BACKGROUND

Integrated primary care programs for patients living with chronic pain which are accessible, interdisciplinary, and patient-centered are needed for preventing chronicity and improving outcomes. Evaluation of the implementation and impact of such programs supports further development of primary care chronic pain management. This study examined patient-reported outcomes among individuals with low back pain (LBP) receiving care in a novel interdisciplinary primary care program.

METHODS

Patients were referred by primary care physicians in four regions of Quebec, Canada, and eligible patients received an evidence-based interdisciplinary pain management program over a six-month period. Patients were screened for risk of chronicity. Patient-reported outcome measures of pain interference and intensity, physical function, depression, and anxiety were evaluated at regular intervals over the six-month follow-up. A multilevel regression analysis was performed to evaluate the association between patient characteristics at baseline, including risk of chronicity, and change in pain outcomes.

RESULTS

Four hundred and sixty-four individuals (mean age 55.4y, 63% female) completed the program. The majority (≥ 60%) experienced a clinically meaningful improvement in pain intensity and interference at six months. Patients with moderate (71%) or high risk (81%) of chronicity showed greater improvement in pain interference than those with low risk (51%). Significant predictors of improvement in pain interference included a higher risk of chronicity, younger age, female sex, and lower baseline disability.

CONCLUSION

The outcomes of this novel LBP program will inform wider implementation considerations by identifying key components for further effectiveness, sustainability, and scale-up of the program.

Physiotherapy assessment and treatment of patients with tibial external fixator: a systematic scoping review

PURPOSE

To map evidence regarding physiotherapy assessment and treatment of patients with tibial external fixator (EF), and to point out literature gaps for further research.

METHODS

Systematic scoping review conducted in four databases. We included both experimental and non-experimental studies involving patients with tibial EF and outcomes of interest. We recorded study design, population, sample size, sample age, reason for EF use, type of surgery, type of EF used, instruments used for assessing function, pain, quality of life, satisfaction, psychosocial aspects, and physiotherapy treatment descriptions from included studies. We categorised data accordingly to outcomes assessed and physiotherapy treatments description.

RESULTS

Eighty-six studies were included involving 3070 patients. Causes of fixator use were traumatic conditions, acquired and congenital deformities, and non-traumatic conditions, like compartmental osteoarthritis. Function was assessed in about three-quarters of included studies, though other outcomes were not presented in most studies. Only one study described satisfactorily the physiotherapy treatment. Almost half of the studies did not provide any description of the rehabilitation process.

CONCLUSIONS

There is little evidence about the assessment of function, pain, quality of life, satisfaction, psychosocial aspects, and other outcomes in tibial EF patients. Physiotherapy treatment in these patients is poorly reported.Protocol registration: Open Science Framework: doi:10.17605/OSF.IO/UT2DA.

Efficacy of Integrated Yoga and Naturopathy With Physiotherapy or Acupuncture for Low Back Pain: A Parallel, Two-Arm, Randomized Trial

INTRODUCTION

Low back pain (LBP) is a musculoskeletal condition that affects many individuals. While physiotherapy and acupuncture are frequently used treatments, determining their specific contributions when used alongside integrated yoga and naturopathy (IYN) therapy for relieving chronic LBP symptoms and enhancing quality of life is important.

METHODOLOGY

In the present prospective randomized comparative trial, a total of 60 participants were divided into the following two groups: physiotherapy with IYN and acupuncture with IYN. The treatment duration was 10 days, and assessments were conducted both before (baseline) and after the intervention. Various assessment tools, such as the visual analog scale (VAS), Oswestry Disability Index (ODI), fingertip-to-floor test (FTF), State-Trait Anxiety Inventory (STAI), and Short Form 36 (SF-36), were utilized. The statistical analysis was performed using SPSS version 21.0 (Armonk, NY: IBM Corp).

RESULTS

The results revealed significant differences in VAS score, ODI, FTF score, STAI score, and SF-36 score between the physiotherapy and acupuncture groups (p<0.001). A t-test for the equality of means and a Mann-Whitney U test were used to compare the two groups; these tests revealed a significant difference in disability levels, range of motion, and state of anxiety. The acupuncture group showed a significant difference in the ODI (15.9 {12.6, 19.3}; p <0.001) and state anxiety (23.0 {20.0, 26.0}; p<0.001) compared to the physiotherapy ODI (22.4 {18.5, 26.4}) and state anxiety (27.5 {25.0, 30.0}). The physiotherapy group showed a significant difference in range of motion (7.7 {5.7, 9.7}; p<0.001) compared to the acupuncture group (11.6 {9.8, 13.5}).

CONCLUSION

The present study findings revealed that both physiotherapy and acupuncture, as interventions along with integrated yoga and naturopathy may be considered an effective treatment strategy for chronic LBP.

Efficacy of Core-Strengthening and Intensive Dynamic Back Exercises on Pain, Core Muscle Endurance, and Functional Disability in Patients with Chronic Non-Specific Low Back Pain: A Randomized Comparative Study

BACKGROUND

Chronic back pains are progressively disabling working individuals, including 60-80% of the general population, for which their diagnosis is challenging to healthcare workers worldwide, thereby becoming a burden to nations.

PURPOSE

The study aimed to investigate the efficacy of core strengthening exercise (CSE) and intensive dynamic back exercise (IDBE) on pain, core muscle endurance, and functional disability in patients with chronic non-specific low back pain (LBP).

METHODS

The study was based on a three-arm parallel-group randomized control design. Forty-five participants with chronic non-specific LBP were recruited and randomly divided into the CSE, IDBE, and Control groups. The CSE and IDBE groups received CSE and IDBE, respectively. However, the Control group received no intervention. Numeric pain rating scale, Oswestry Disability Index, core flexors, extensors, and side bridge tests assessed pain intensity, functional disability, and endurance of core muscles. Outcome scores for the dependent variables were collected at baseline (pre-intervention) and six-week post-intervention. There were no follow-up measurements in this study. A one-way multivariate analysis of covariance (MANCOVA) was used to analyze the intervention effects on the outcomes within groups and between groups, respectively; keeping the significance-level alpha at 95%, i.e., p < 0.05. A univariate F-test was performed to observe the superiority of one treatment over another. Pearson's correlation coefficient test was conducted to determine a relation between the dependent variables. In all statistical analyses, the level of significance α was kept at 0.05.

RESULTS

All forty-five out of sixty-three participants with chronic non-specific low back pain (male, 32 and female, 23; average age, 20.24 ± 1.46 years; average pain duration, 19.6 ± 5.42 weeks) completed the study and their data were analyzed. The MANCOVA test showed a significant difference between the treatment groups on the combined multiple endurance tests for the core muscles (flexors, extensors, side bridge tests to the right and left), Visual Analog Scale (VAS), and Oswestry Disability Index (ODI) scores after controlling for baseline scores of all the dependent variables: F (6, 12) = 23.381; p < 0.05; Wilks' Λ = 0.033; partial η2 = 0.819. A post hoc pair-wise comparison followed by a univariate F-test indicated that a significant improvement was found between the CSE vs. IDBE vs. Control groups on the post-test scores of all the dependent variables except VAS and EET (CSE vs. IDBE only). A Pearson's correlation coefficient test revealed a notable relation between the dependent variables.

CONCLUSIONS

The experimental group CSE was found to be more effective than IDBE on improving functional disability, cores' flexors, and side bridges' endurance tests than IDBE. The magnitude of this improvement exceeded the minimal clinically important difference (MCID), suggesting a clinically relevant enhancement in functional disability, core flexors, and side bridge endurance for participants engaged in CSE. However, CSE vs. IDBE revealed non-significant differences on reducing pain and core extensors' endurance. The absence of statistically significant differences suggests that the observed changes did not exceed the established MCID for pain intensity and core extensors' endurance. In addition, partial eta-squared value revealed the superiority of CSE over IDBE and Control groups. This suggests that the observed differences between the two interventions are not only statistically significant, but also clinically relevant, surpassing the established MCID.

Trajectories of Adherence to Home-Based Exercise Recommendations Among People With Low Back Pain: A Longitudinal Analysis

OBJECTIVE

This study aimed to examine the presence of distinct trajectories of adherence to home-based exercise recommendations among people with low back pain (LBP). This study also aimed to identify differences in baseline characteristics among groups.

METHODS

This study was a secondary analysis of a prospective, multicenter cluster randomized controlled trial investigating the cost-effectiveness of a stratified blended physical therapist intervention compared to usual care physical therapy in patients with LBP. The intervention group received usual care with integrated support via a smartphone app. A total of 208 patients were recruited from 58 primary care physical therapist practices. Baseline data included patient characteristics, physical functioning, pain intensity, physical activity, fear avoidance, pain catastrophizing, self-efficacy, self-management ability, and health-related quality of life. The Exercise Adherence Scale (score range = 0-100) was used to measure adherence during each treatment session. Latent class growth analysis was used to estimate trajectories of adherence.

RESULTS

Adherence data were available from 173 out of 208 patients (83%). Data were collected during an average of 5.1 (standard deviation [SD] = 2.5) treatment sessions, with total treatment duration of 51 (SD = 41.7) days. Three trajectory classes were identified: "declining adherence" (12%), "stable adherence" (45%), and "increasing adherence" (43%). No differences in baseline characteristic were found between groups.

CONCLUSION

Three adherence trajectories to exercise recommendations were identified in patients with LBP. However, baseline characteristics cannot identify a patient's trajectory group.

IMPACT

Despite the presence of distinct trajectories of adherence in patients with LBP, physical therapists should not attempt to place a patient in a trajectory group at the start of treatment. Instead, adherence should be closely monitored as treatment progresses and supported when required as part of an ongoing process.

Evidence- and data-driven classification of low back pain via artificial intelligence: Protocol of the PREDICT-LBP study

In patients presenting with low back pain (LBP), once specific causes are excluded (fracture, infection, inflammatory arthritis, cancer, cauda equina and radiculopathy) many clinicians pose a diagnosis of non-specific LBP. Accordingly, current management of non-specific LBP is generic. There is a need for a classification of non-specific LBP that is both data- and evidence-based assessing multi-dimensional pain-related factors in a large sample size. The "PRedictive Evidence Driven Intelligent Classification Tool for Low Back Pain" (PREDICT-LBP) project is a prospective cross-sectional study which will compare 300 women and men with non-specific LBP (aged 18-55 years) with 100 matched referents without a history of LBP. Participants will be recruited from the general public and local medical facilities. Data will be collected on spinal tissue (intervertebral disc composition and morphology, vertebral fat fraction and paraspinal muscle size and composition via magnetic resonance imaging [MRI]), central nervous system adaptation (pain thresholds, temporal summation of pain, brain resting state functional connectivity, structural connectivity and regional volumes via MRI), psychosocial factors (e.g. depression, anxiety) and other musculoskeletal pain symptoms. Dimensionality reduction, cluster validation and fuzzy c-means clustering methods, classification models, and relevant sensitivity analyses, will classify non-specific LBP patients into sub-groups. This project represents a first personalised diagnostic approach to non-specific LBP, with potential for widespread uptake in clinical practice. This project will provide evidence to support clinical trials assessing specific treatments approaches for potential subgroups of patients with non-specific LBP. The classification tool may lead to better patient outcomes and reduction in economic costs.

Opioid analgesia for acute low back pain and neck pain (the OPAL trial): a randomised placebo-controlled trial

BACKGROUND

Opioid analgesics are commonly used for acute low back pain and neck pain, but supporting efficacy data are scarce. We aimed to investigate the efficacy and safety of a judicious short course of an opioid analgesic for acute low back pain and neck pain.

METHODS

OPAL was a triple-blinded, placebo-controlled randomised trial that recruited adults (aged ≥18 years) presenting to one of 157 primary care or emergency department sites in Sydney, NSW, Australia, with 12 weeks or less of low back or neck pain (or both) of at least moderate pain severity. Participants were randomly assigned (1:1) using statistician-generated randomly permuted blocks to guideline-recommended care plus an opioid (oxycodone-naloxone, up to 20 mg oxycodone per day orally) or guideline-recommended care and an identical placebo, for up to 6 weeks. The primary outcome was pain severity at 6 weeks measured with the pain severity subscale of the Brief Pain Inventory (10-point scale), analysed in all eligible participants who provided at least one post-randomisation pain score, by use of a repeated measures linear mixed model. Safety was analysed in all randomly assigned eligible participants. The trial was registered with the Australian New Zealand Clinical Trials Registry (ACTRN12615000775516).

FINDINGS

Between Feb 29, 2016, and March 10, 2022, 347 participants were recruited (174 to the opioid group and 173 to the placebo group). 170 (49%) of 346 participants were female and 176 (51%) were male. 33 (19%) of 174 participants in the opioid group and 25 (15%) of 172 in the placebo group had discontinued from the trial by week 6, due to loss to follow-up and participant withdrawals. 151 participants in the opioid group and 159 in the placebo group were included in the primary analysis. Mean pain score at 6 weeks was 2·78 (SE 0·20) in the opioid group versus 2·25 (0·19) in the placebo group (adjusted mean difference 0·53, 95% CI -0·00 to 1·07, p=0·051). 61 (35%) of 174 participants in the opioid group reported at least one adverse event versus 51 (30%) of 172 in the placebo group (p=0·30), but more people in the opioid group reported opioid-related adverse events (eg, 13 [7·5%] of 174 participants in the opioid group reported constipation vs six [3·5%] of 173 in the placebo group).

INTERPRETATION

Opioids should not be recommended for acute non-specific low back pain or neck pain given that we found no significant difference in pain severity compared with placebo. This finding calls for a change in the frequent use of opioids for these conditions.

The effectiveness of different aerobic exercises to improve pain intensity and disability in chronic low back pain patients: a systematic review

Background: Physical activity, including aerobic exercise, is highly recommended for chronic low back pain (CLBP) patients to improve pain intensity and functional disability. Objectives: To assess the effectiveness of different aerobic exercises to reduce pain intensity and functional disability in patients with CLBP. Methods: A computer-aided search was performed to find Randomised Controlled Trials (RCTs) that evaluated the effectiveness of different aerobic exercises in CLBP. Articles published between January 2007 to December 2020 were included in the review. Quality assessment using the PEDro scale, extraction of relevant information, and evaluation of outcomes were done by two reviewers independently. Results: A total of 17 studies were included that involved 1146 participants. Outcomes suggested that aerobic exercise combined with other interventions was more effective than aerobic exercise alone. Aerobic exercise with higher frequency (≥ 5 days/week) and longer duration (≥ 12 weeks) were effective to gain clinically significant (≥ 30%) improvements. Environment and using pedometer did not seem to influence the outcomes. Conclusions: Pain intensity and functional disability in CLBP patients can be minimized by prescribing aerobic exercise. However, to get better improvements, aerobic exercise should be done in combination with other interventions and at optimum frequency and duration. Further studies should emphasize examining the optimal doses and duration of different aerobic exercises.

Effectiveness of Cognitive Functional Therapy for Reducing Pain and Disability in Chronic Low Back Pain: A Systematic Review and Meta-analysis

OBJECTIVE: We aimed to evaluate whether cognitive functional therapy (CFT) is an effective treatment for adults with chronic low back pain (LBP). DESIGN: Intervention systematic review with meta-analysis. LITERATURE SEARCH: We searched 4 electronic databases (CENTRAL, CINAHL, MEDLINE, and Embase) and 2 clinical trial registers (ClinicalTrials. gov and the EU Clinical Trials Register) from inception up to March 2022. STUDY SELECTION CRITERIA: We included randomized controlled trials evaluating CFT for adults with LBP. DATA SYNTHESIS: The primary outcomes were pain intensity and disability. Secondary outcomes were psychological status, patient satisfaction, global improvement, and adverse events. Risk of bias was assessed using the Cochrane Risk of Bias 2 tool. Certainty of evidence was assessed using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach. Random-effects meta-analysis with the Hartung-Knapp-Sidik-Jonkman adjustment was used to estimate pooled effects. RESULTS: Fifteen trials were included (9 ongoing and 1 terminated), of which 5 provided data (n = 507; n = 262 CFT, and n = 245 control). There was very low certainty for the effectiveness of CFT compared to manual therapy plus core exercises (2 studies, n = 265) for reducing pain intensity (mean difference: -1.02/10, 95% confidence interval: -14.75, 12.70) and disability (mean difference: -6.95/100, 95% confidence interval: -58.58, 44.68). Narrative synthesis showed mixed results for pain intensity, disability, and secondary outcomes. No adverse events were reported. All studies were judged to be at high risk of bias. CONCLUSION: Cognitive functional therapy may not be more effective than other common interventions for reducing pain and disability in adults with chronic LBP. The effectiveness of CFT is very uncertain and will remain so until higher-quality studies are available. J Orthop Sports Phys Ther 2023;53(5):1-42.

High levels of back disability, not back pain, are associated with reduced physical activity across key activity domains

BACKGROUND

Although remaining physically active is the cornerstone of management for low back pain, our understanding of the physical activity performed by those with back pain is limited.

OBJECTIVES

To examine the physical activity reported by individuals with different levels of low back pain and disability across key activity domains.

DESIGN

Community-based, cross-sectional study.

METHODS

542 women were recruited from a research database formed from an electoral roll and completed validated, self-report questionnaires. The amount and intensity of physical activity was reported using the International Physical Activity Questionnaire. Low back pain and disability were examined using the Graded Chronic Pain Scale. Participants were categorised into no, low or high pain and disability groups.

RESULTS

Individuals who reported high disability performed 55% of the physical activity of those without disability (MET(hours/week):median(95%CI) = 27.1(13.2-41.0); 48.8(37.8-59.9),p = 0.01), including less moderate (18.0(10.4-25.6); 31.0(24.0-38.1),p = 0.007), and domestic and gardening activity (14.7(7.2-22.3); 25.7(19.8-31.7),p = 0.001). Fewer women with high disability performed vigorous (OR(95%CI) = 0.29(0.13-0.65),p = 0.002) and leisure activities (0.17(0.04-0.75),p = 0.02) compared to those with no disability. Those with low disability reported less leisure activity ((0.55(0.35-0.88),p = 0.01), but more work-related activities and active transport than individuals without disability (1.65(1.01-2.7),p = 0.04; 1.6(1.04-2.6),p = 0.03). There were no differences in activity between pain groups, with the exception of those with low intensity pain performing less leisure activity (0.51(0.30-0.88),p = 0.01).

CONCLUSIONS

Individuals who reported high back disability, not back pain, were found to perform reduced physical activity, including less total, moderate, vigorous, and discretionary activity. These findings highlight the altered activity levels of people with back disability and the need to examine its impact on their health and wellbeing.

Management of Low Back Pain: Do Physiotherapists Know the Evidence-Based Guidelines?

BACKGROUND

Clinical practice guidelines promote bio-psychosocial management of patients suffering from low back pain (LBP). The objective of this study was to examine the current knowledge, attitudes and beliefs of physiotherapists about a guideline-adherent approach to LBP and to assess the ability of physiotherapists to recognise signs of a specific LBP in a clinical vignette.

METHODS

Physiotherapists were recruited to participate in an online study. They were asked to indicate whether they were familiar with evidence-based guidelines and then to fill in the Health Care Providers' Pain and Impairment Relationship Scale (HC-PAIRS), Back Pain Attitudes Questionnaire (Back-PAQ), Neurophysiology of Pain Questionnaire (NPQ), as well as questions related to two clinical vignettes.

RESULTS

In total, 527 physiotherapists participated in this study. Only 38% reported being familiar with guidelines for the management of LBP. Sixty-three percent of the physiotherapists gave guideline-inconsistent recommendations regarding work. Only half of the physiotherapists recognised the signs of a specific LBP.

CONCLUSIONS

The high proportion of physiotherapists unfamiliar with guidelines and demonstrating attitudes and beliefs not in line with evidence-based management of LBP is concerning. It is crucial to develop efficient strategies to enhance knowledge of guidelines among physiotherapists and increase their implementation in clinical practice.

Environmental Risk Assessment of Low Back Pain in ICU Nurses: An Instrument Development Study

Aim

To develop a valid, reliable assessment tool to measure risk factors associated to low back pain (LBP) in intensive care unit (ICU) nurses.

Background

LBP is defined as the pain extending from the 12th rib to the iliac crest and often coexists with buttock pain. Nursing has been identified among the top professions at risk of LBP. A mean of 70% prevalence per year in ICU nurses was reported, exceeding those employed in heavy industry. Environmental factors in workplace were also most important risks related to LBP in this population except factors including individual, physical, psychosocial, and lifestyle. However, there is lack of tools to assess environmental risk related to LBP for nurse managers currently.

Methods

Focus group interviews, field research, and panel discussion were used to develop item pool. Two-round expert reviews and preinvestigation were carried out to form initial scale named Environmental Risk Assessing Instrument-Occupational Low Back Pain in Nurses (ERAI-N). A cross-sectional survey with 188 ICU participants in Hunan Province in China was implemented to collect data. Cronbach's alpha, split-half reliability, and test-retest reliability were used to test ERAI-N's reliability. Expert review was performed to test ERAI-N's content validity, and confirmatory factor analysis (CFA) was performed to assess its construct validity, being carried out in IBM SPSS Amos 26 Graphics.

Results

Final version of ERAI-N scale had five dimensions with 18 items that were space, equipment, belief, guideline, and safe culture. ERAI-N scale's score of Cronbach's alpha, Guttman split-half, and intraclass correlation coefficient (ICC) was 0.958, 0.927, and 0.994, respectively. Item-level content validity scores ranged from 0.89 to 1.0, and scale-level content validity was 0.983. Standardized factor loadings ranged from 0.567 to 0.974. Model adjusted fit statistics were as follows: the chi-square statistic and degrees of freedom (χ 2/df) = 3.943, root mean square error of approximation (RMSEA) = 0.071, incremental fit index (IFI) = 0.905, comparative fit index (CFI) = 0.904, parsimony normed fit index (PNFI) = 0.641, and parsimonious comparative fit index (PCFI) = 0.661.

Conclusions

ERAI-N scale had moderate reliability, content validity, and construct validity. Implications for Nursing Management. Designers may use ERAI-N scale to plan the interior layout when design a new ICU. Nurse managers might utilize this instrument as a managing tool to assess whether there is environmental risk factors related to LBP in ICU.

The group mechanism in treatment: group identification and cohesion contributes to reducing chronic lower back pain by increasing personal control

PURPOSE

There is increasing recognition of the contribution that group processes, particularly identification and cohesion, make to outcomes of group delivered health treatments. This study examined the role that these particular group processes play in the treatment of lower back pain, and a theorised mechanism of personal control through which group treatment might enhance outcomes.

METHODS

Participants (N = 85) elected to either receive NeuroHAB^®, a defined functional movement therapy of 8 weeks duration, or continue with treatment-as-usual (TAU). Pain intensity and disability were assessed at baseline (T1) and post-intervention or 8 weeks later (T2), as well as at a 1-month follow-up (T3). Only the NeuroHAB^® participants additionally completed weekly questionnaires that measured treatment group identification, cohesion, and personal control.

RESULTS

NeuroHAB^® was significantly more effective than TAU in reducing pain intensity and disability at T2 and T3. Furthermore, among NeuroHAB^® recipients, stronger treatment group identification and cohesion early in the program predicted better pain outcomes over time, and this relationship was fully mediated by perceptions of personal control.

CONCLUSION

These data provide further support for the role of group identification and cohesion as a contributing mechanism of change in group-based treatments and extend this to the domain of pain management.Implications for RehabilitationA focus on defined functional movement therapy, as offered by the NeuroHAB^® group program, was found to improve pain outcomes in patients with lower back pain.A key ingredient in the NeuroHAB^® rehabilitation program was its group delivery.Group delivery supported treatment group identification and cohesion which, through enhancing the perception of personal control, reduced pain intensity and disability.

Comparative effectiveness and safety of analgesic medicines for adults with acute non-specific low back pain: systematic review and network meta-analysis

OBJECTIVE

To evaluate the comparative effectiveness and safety of analgesic medicines for acute non-specific low back pain.

DESIGN

Systematic review and network meta-analysis.

DATA SOURCES

Medline, PubMed, Embase, CINAHL, CENTRAL, ClinicalTrials.gov, clinicialtrialsregister.eu, and World Health Organization's International Clinical Trials Registry Platform from database inception to 20 February 2022.

ELIGIBILITY CRITERIA FOR STUDY SELECTION

Randomised controlled trials of analgesic medicines (eg, non-steroidal anti-inflammatory drugs, paracetamol, opioids, anti-convulsant drugs, skeletal muscle relaxants, or corticosteroids) compared with another analgesic medicine, placebo, or no treatment. Adults (≥18 years) who reported acute non-specific low back pain (for less than six weeks).

DATA EXTRACTION AND SYNTHESIS

Primary outcomes were low back pain intensity (0-100 scale) at end of treatment and safety (number of participants who reported any adverse event during treatment). Secondary outcomes were low back specific function, serious adverse events, and discontinuation from treatment. Two reviewers independently identified studies, extracted data, and assessed risk of bias. A random effects network meta-analysis was done and confidence was evaluated by the Confidence in Network Meta-Analysis method.

RESULTS

98 randomised controlled trials (15 134 participants, 49% women) included 69 different medicines or combinations. Low or very low confidence was noted in evidence for reduced pain intensity after treatment with tolperisone (mean difference -26.1 (95% confidence intervals -34.0 to -18.2)), aceclofenac plus tizanidine (-26.1 (-38.5 to -13.6)), pregabalin (-24.7 (-34.6 to -14.7)), and 14 other medicines compared with placebo. Low or very low confidence was noted for no difference between the effects of several of these medicines. Increased adverse events had moderate to very low confidence with tramadol (risk ratio 2.6 (95% confidence interval 1.5 to 4.5)), paracetamol plus sustained release tramadol (2.4 (1.5 to 3.8)), baclofen (2.3 (1.5 to 3.4)), and paracetamol plus tramadol (2.1 (1.3 to 3.4)) compared with placebo. These medicines could increase the risk of adverse events compared with other medicines with moderate to low confidence. Moderate to low confidence was also noted for secondary outcomes and secondary analysis of medicine classes.

CONCLUSIONS

The comparative effectiveness and safety of analgesic medicines for acute non-specific low back pain are uncertain. Until higher quality randomised controlled trials of head-to-head comparisons are published, clinicians and patients are recommended to take a cautious approach to manage acute non-specific low back pain with analgesic medicines.

The role of spinal surgery in the treatment of low back pain

Low back pain (LBP) is common and a leading cause of disability and lost productivity worldwide. Acute LBP is frequently self-resolving, but recurrence is common, and a significant proportion of patients will develop chronic pain. This transition is perpetuated by anatomical, biological, psychological and social factors. Chronic LBP should be managed with a holistic biopsychosocial approach of generally non-surgical measures. Spinal surgery has a role in alleviating radicular pain and disability resulting from neural compression, or where back pain relates to cancer, infection, or gross instability. Spinal surgery for all other forms of back pain is unsupported by clinical data, and the broader evidence base for spinal surgery in the management of LBP is poor and suggests it is ineffective. Emerging areas of interest include selection of a minority of patients who may benefit from surgery based on spinal sagittal alignment and/or nuclear medicine scans, but an evidence base is absent. Spinal surgery for back pain has increased substantially over recent decades, and disproportionately among privately insured patients, thus the contribution of industry and third-party payers to this increase, and their involvement in published research, requires careful consideration.

Reciprocity in Low Back Pain Care and Its Role in Power Dynamics: A Give-and-Take Approach

OBJECTIVE

The shift toward patient-centered care in physical therapy fostered a deeper consideration of power-sharing in clinical interactions. Elements of reciprocity may enhance such power considerations between physical therapist and patients, but there has been little investigation into how reciprocity is enacted in physical therapy, its value, and how to improve it if required. This study investigates forms of reciprocity during physical therapist-patient interactions in low back pain (LBP) care with the aim of enhancing patient-centered approaches.

METHODS

The qualitative design involved (1) ethnographic observations at a fee-for-service practice in Australia, and (2) reflexive discussions between researchers and participating clinicians. To understand reciprocity, the analysis drew from the concepts of "accepting'"(or "blocking") "offers" that have been previously applied to physical therapy interactions. The analysis is a sub-study using a larger dataset and analyses in which we partnered with physical therapists and people living with LBP.

RESULTS

Forty-nine observations and 13 reflexive discussions were undertaken with 42 people with LBP and 10 physical therapists. Analysis developed 3 themes suggesting that forms of reciprocity depended on physical therapists accepting or blocking patients' offers, inviting patients to make an offer, and offering personal stories. These elements of reciprocity are relevant to power-sharing during interactions and may impact patient-centered care.

CONCLUSION

Our results suggest that attending to forms of reciprocity can help physical therapists shift power in clinical interactions. By inviting and accepting "offers," physical therapists may build collaborative interactions, support individuals to guide the treatment narrative, and shift away from biomedically centered management approaches. Such recommendations create reciprocal environments that might enhance patient-centered care.

IMPACT

This is one of the few studies to explore how reciprocity is enacted in interactions between physical therapists and s with LBP. Our findings highlight how engaging with the concept of reciprocity could assist with sharing power, improving physical therapist-patient relationships, and enhancing patient-centered care.

Disability and return to work after a multidisciplinary intervention for (sub)acute low back pain: A systematic review

Objective

This systematic review aimed to examine pain, functional status and return to work after a multidisciplinary intervention, with or without additional workplace intervention, for (sub)acute low back pain among adults.

Data sources

A comprehensive search was completed (November 2022) in six electronic databases (Embase, MEDLINE, Web of Science, Cochrane, CENTRAL and Scopus) and in the reference list of all identified studies.

Review methods

The search results were screened against predefined eligibility criteria by two independent researchers. Included articles were systematic reviews or randomized controlled trials examining the effect of a multidisciplinary intervention, with or without workplace intervention, in working adults with (sub)acute low back pain. Relevant information was summarized and clustered, and the methodological quality and certainty of evidence were assessed respectively using the RoB 2-tool, the ROBIS tool and the GRADE criteria.

Results

The search resulted in a total of 3020 articles. After the screening process, 12 studies remained (11 randomized controlled trials and 1 systematic review), which studied overall 2751 patients, with a follow-up period of at least 12 months.

Conclusions

A multidisciplinary intervention is favorable compared to usual care for pain intensity and functional status but this is less clear for return to work. Comparable work-related effects were found when comparing a multidisciplinary intervention with a less extensive intervention, whereas uncertainties exist regarding outcomes of pain intensity and functional status. Furthermore, adding a workplace intervention to usual care and subdividing patients based on work-related characteristics seems beneficial for return to work.

The perceptions of individuals with musculoskeletal disorders towards prognosis: An exploratory qualitative study

QUESTION(S)

How do individuals living with musculoskeletal disorders perceive the concept of prognosis?

DESIGN

Exploratory phenomenological study.

PARTICIPANTS

Individuals aged 18 years or older currently experiencing a musculoskeletal disorder.

DATA ANALYSIS

Single semi-structured one-on-one interviews were conducted. Data was analysed using inductive coding and thematic analysis.

RESULTS

Five themes were identified. First, participants defined prognosis as the likely outcome associated with their diagnosis. Their prognosis was often associated with outcomes related to pain, tissue health, and function. Second, participants perceived pain as having a negative impact on their prognosis by limiting their function and having a psychological impact. Third, participants held biomedical views in that tissue health was perceived as a cause for their pain and that tissue healing was essential for pain cessation. It was also difficult for participants to distinguish between pain related to tissue damage, and pain that was not. Fourth, participants use their ability to complete leisure and functional activities to determine the success of their recovery. Finally, participants perceived receiving individual prognoses for pain, tissue health, and function that may be simultaneously occurring as both important and beneficial.

CONCLUSION

Overall, participants viewed receiving prognostic information as important and beneficial. When constructing their views on prognosis participants perceived that pain, tissue health, and functional ability could all impact upon prognosis, whilst having a prognosis of their own. Physiotherapists should consider conceptualising and discussing prognosis in terms of pain, tissue health, and function when managing musculoskeletal disorders.

Feasibility of testing the effectiveness of a theory-informed intervention to reduce imaging for low back pain: a pilot cluster randomised controlled trial

BACKGROUND

General medical practitioner (GP) recruitment and subsequent data collection in clinical practice are challenging and may limit successful completion of a large-scale trial. The aim of this study was to assess the feasibility of undertaking a cluster randomised controlled trial to test an intervention to reduce non-indicated imaging for low back pain in general medical practice.

METHODS

A pilot cluster randomised controlled trial was performed, with recruitment of GPs and randomisation of GP clinics. All GPs attended a training session and were asked to record low back pain codes in electronic medical records for any low back pain presentations. Intervention group GPs were trained in the use of a patient education booklet to be used during low back pain patient visits. Control group GPs provided usual care. Outcomes for the proposed trial were collected to determine feasibility. GP recruitment was assessed as the proportion of GPs approached who consented to participate. Low back pain imaging outcomes were collected from electronic medical records (counts of patients presenting with low back pain) and from Australian healthcare administrative (Medicare) data (counts of imaging use). GP compliance with study procedures was assessed and qualitative data reported.

RESULTS

Thirty-four GP clinics were approached, with four participating (12%). At these clinics, 13/19 (68%) GPs consented to participate, and 10/19 (53%) started the study. Outcome data were collected from medical records for all GPs. Three GPs (30%) withdrew consent to access Medicare data, limiting reporting of imaging outcome measures. Three GPs (30%) self-reported low compliance entering low back pain codes.

CONCLUSIONS

This pilot cluster randomised controlled trial demonstrated the feasibility of many aspects of a full-scale effectiveness study, while also identifying a number of challenges that need to be resolved. Recommendations related to GP recruitment, study compliance, data collection, and outcome measures were made to increase the success of a future trial.

Biomarkers for Chronic Pain: Significance and Summary of Recent Advances

Chronic pain can be difficult to predict and a challenge to treat. Biomarkers for chronic pain signal an opportunity for advancements in both management and prevention, and through their research and development offer new insights into the complex processes at play. This review considers the latest research in chronic pain biomarker development and considers how close we are to bringing these from bench to bedside. While some headway has been made that offers efficiencies in patient selection, it is unlikely that a single test will encompass the variety of chronic pain phenotypes. We offer some insights for the near future in biomarker development and areas of continued unmet need.

Effectiveness of Opioid Analgesic Medicines Prescribed in or at Discharge From Emergency Departments for Musculoskeletal Pain : A Systematic Review and Meta-analysis

BACKGROUND

The comparative benefits and harms of opioids for musculoskeletal pain in the emergency department (ED) are uncertain.

PURPOSE

To evaluate the comparative effectiveness and harms of opioids for musculoskeletal pain in the ED setting.

DATA SOURCES

Electronic databases and registries from inception to 7 February 2022.

STUDY SELECTION

Randomized controlled trials of any opioid analgesic compared with placebo or a nonopioid analgesic administered or prescribed to adults in or on discharge from the ED.

DATA EXTRACTION

Pain and disability were rated on a scale of 0 to 100 and pooled using a random-effects model. Certainty of evidence was assessed using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) framework.

DATA SYNTHESIS

Forty-two articles were included (n = 6128). In the ED, opioids were statistically but not clinically more effective in reducing pain in the short term (about 2 hours) than placebo and paracetamol (acetaminophen) but were not clinically or statistically more effective than nonsteroidal anti-inflammatory drugs (NSAIDs) or local or systemic anesthetics. Opioids may carry higher risk for harms than placebo, paracetamol, or NSAIDs, although evidence is very uncertain. There was no evidence of difference in harms associated with local or systemic anesthetics.

LIMITATIONS

Low or very low GRADE ratings for some outcomes, unexplained heterogeneity, and little information on long-term outcomes.

CONCLUSION

The risk-benefit balance of opioids versus placebo, paracetamol, NSAIDs, and local or systemic anesthetics is uncertain. Opioids may have equivalent pain outcomes compared with NSAIDs, but evidence on comparisons of harms is very uncertain and heterogeneous. Although factors such as route of administration or dosage may explain some heterogeneity, more work is needed to identify which subgroups will have a more favorable benefit-risk balance for one analgesic over another. Longer-term pain management once dose thresholds are reached is also uncertain.

Physical therapists and public perceptions of telerehabilitation: An online open survey on acceptability, preferences, and needs

BACKGROUND

During the COVID-19 pandemic, telerehabilitation allowed the continuation of physical therapy care in parallel with public health measures to prevent the virus spread. However, in low- and middle-income countries including Brazil, telerehabilitation was unfamiliar to most of the population.

OBJECTIVE

To investigate acceptability, preferences, and needs in telerehabilitation by Brazilian physical therapists and the general population.

METHODS

We conducted an observational cross-sectional study with an online survey consisting of 13 multiple-choice items. Items were distributed among acceptability, preferences, and needs sections, and encompassed confidence in delivering or receiving telerehabilitation, its perceived efficacy and costs, and suitable content.

RESULTS

A total of 1107 responses were registered, 717 from physical therapists. Half of them self-reported confidence in conducting telerehabilitation through the internet (synchronous or asynchronous). The same proportion disagreed that telerehabilitation is as effective as in-person interventions. Physical therapists agreed telerehabilitation should contain educational, self-management strategies, and exercises information, but the general population endorsed the provision of technical advice on exercise execution. The general population mostly reported that telerehabilitation could help their specific health condition (86%), but only 14% of respondents would pay the same as they pay for in-person consultations. Participants reported an overall preference for synchronous communication and concern about the lack of a hands-on approach.

CONCLUSION

Physical therapists and the general population appear to demonstrate apprehension towards telerehabilitation. Insufficient preparation or inadequate knowledge might influence participants' acceptance, preferences, and needs.

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

OBJECTIVE

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

METHODS

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

RESULTS

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

CONCLUSION

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

"Myths and Facts" Education Is Comparable to "Facts Only" for Recall of Back Pain Information but May Improve Fear-Avoidance Beliefs: An Embedded Randomized Trial

OBJECTIVE

To assess the effectiveness of patient education with "myths and facts" versus "facts only" on recall of back pain information and fear-avoidance beliefs in patients with chronic low back pain (LBP).

DESIGN

Randomized Study Within A Trial.

METHODS

One hundred fifty-two participants with chronic LBP were included. Participants allocated to the "facts only" group received an information sheet with 6 LBP facts, whereas those allocated to the "myths and facts" group received the same information sheet, with each myth refuted by its respective fact. The primary outcome was a correct recall of back pain facts, and the secondary outcome was the physical activity component of the Fear-Avoidance Beliefs Questionnaire (FABQ-PA), 2 weeks after the provision of the information sheet.

RESULTS

There was no evidence of a difference in the proportion of participants with a correct recall between the "myths and facts" and "facts only" groups (odds ratio = 0.98; 95% confidence interval [CI]: 0.48, 1.99) and no significant difference in FABQ-PA mean scores between groups (-1.58; 95% CI: -3.77, 0.61). Sensitivity analyses adjusted for prognostic factors showed no difference in information recall but a larger difference in FABQ-PA scores (-2.3; 95% CI: -4.56, -0.04).

CONCLUSION

We found no overall difference in the recall of back pain information for patients provided with "myths and facts" compared with that for patients provided with "facts only" and a slight reduction in fear-avoidance beliefs for physical activity using "myths and facts" compared with that using "facts only," but the meaningfulness of this result is uncertain.

Deprescribing paracetamol in pain conditions: A scoping review

OBJECTIVE

To examine evidence on deprescribing paracetamol in pain conditions and inform future strategies for paracetamol deprescription.

DESIGN

Scoping review.

PARTICIPANTS

Adults with pain conditions, taking paracetamol.

RESULTS

After two independent teams of reviewers screening for titles, abstracts, and then full texts, 16 original articles were included. Deprescribing strategies were grouped into 5 categories: (1) Pharmacological, (2) Psychological, (3) Physiological, (4) Policy, and (5) Combination. We found strategies were predominately consumer-focused, conducted in community settings and involved individuals experiencing musculoskeletal pain (such as low back pain and osteoarthritis). A total of twelve studies investigated interventions targeting dose reduction and four studies examined interventions focusing on discontinuation of paracetamol. The most common strategies used to deprescribe paracetamol in pain conditions were physiological strategies, followed by psychological strategies. All included studies demonstrated some level of effectiveness to deprescribe paracetamol in a pain conditions through dose reduction or discontinuation, although the effectiveness of deprescribing strategies were highly variable, ranging from the majority of participants discontinuing their paracetamol use, to less than 10% reducing their paracetamol use upon the latest follow-up.

CONCLUSIONS

There are clear opportunities for prospective trials to be designed more purposely and primarily focused to influence reduction and cessation of paracetamol for specific pain conditions where deprescription is appropriate.

The Role of Exercise in Treating Low Back Pain

ABSTRACT

The purpose of this review is to highlight the role of exercise in preventing and managing acute and chronic axial low back pain (LBP). LBP is one of the leading contributors to years lived with disability as well as health care expenditures in the United States. With an expected increase in prevalence due to an aging population, sports medicine providers have a unique opportunity to provide effective treatment strategies incorporating exercise advice and prescription. Although the majority of individuals with acute LBP will have their symptoms resolve spontaneously, almost 40% will have recurrence or develop chronic LBP within 1 year. No single exercise method has been shown to be more effective than another. The evidence for walking programs, aerobic exercise, yoga, Pilates, and tai chi for LBP is discussed. Our review summarizes the beneficial role of a personalized exercise program and related counseling strategies in the prevention and management of LBP.

What messages predict intention to self-manage low back pain? A study of attitudes towards patient education

ABSTRACT

This observational study evaluated people's attitudes towards educational statements and tested whether this predicted intention to self-manage low back pain (LBP). People with or without LBP who were older than 18 years and fluent in written English were recruited. Participants completed an online survey asking demographic questions and questions on the presence or absence of LBP, its duration, and intensity. We assessed attitude toward educational statements and conducted linear regression analyses to investigate the relationship between attitude toward each statement and intention to self-manage. We recruited 656 participants, n = 345 (53.6%), with LBP of varying duration. On average, participants had a positive attitude toward all statements except one; participants with chronic LBP had a negative attitude toward a statement relating to the cause of LBP. The effect of attitude on intention to self-manage was dependent on whether someone had LBP and for how long. For example, increased intention to self-manage was predicted by a positive attitude toward educational statements related to staying active (β = 0.22 [CI 0.11-0.33]) in participants without pain, statements about reassurance (β = 0.33 [CI 0.16-0.49]) for participants with acute or subacute LBP, and statements about the severity of back pain (β = 0.25 [CI 0.18-0.33]) for participants with chronic LBP. We noted differences in attitude toward educational messages and individuals' intention to self-manage LBP depending on pain duration. Self-management could be encouraged with specific reassurance in people with acute or subacute LBP and education about severity in people with chronic LBP.

Non-surgical therapy for the treatment of chronic low back pain in patients with Modic changes: A systematic review of the literature

Background

In absence of uniform therapeutic recommendations, knowledge of the available treatment options for Modic changes (MCs) patients and their safety and effectiveness would be crucial and significant for clinicians and such patients.

Objectives

The aim of this study was to provide a systematic review of available studies on non-surgical treatments of MCs.

Methods

We performed a systematic review of multiple electronic databases including PubMed, Web of Science, Embase, Cochrane Library, and China National Knowledge Infrastructure for the period until 31st August 2021 to search for studies on non-surgical treatments for MCs in accordance with the guidance of the Cochrane Handbook. Potential studies were screened by their titles and abstracts. The methodological quality of the included studies was independently evaluated by two authors. Final recommendations for the included interventions were developed based on grades of recommendations. The narrative format was adopted to synthesize the findings of the present work.

Results

Fifth studies involving a total of 1147 patients were identified for this systematic review. The results of this review demonstrated that spinal manipulation has been suggested as an alternative option for patients with MCs. However, there was insufficient evidence to support that patients with MCs can benefit from the medication and wearing the rigid lumbar brace. Moreover, the rationale and safety for the use of antibiotics in such patients remain highly controversial. Low evidence revealed that exercise therapy might decrease pain intensity only for special subgroups of MCs patients.

Conclusions

There is not yet enough evidence to suggest that non-surgical treatments are useful for patients with MCs. Further high-quality, multicenter trials are required to validate the effectiveness of these non-surgical treatments.

A biopsychosocial examination of chronic back pain, limitations on usual activities, and treatment in Brazil, 2019

Background

Chronic back pain is prevalent in Brazil, leading to enormous healthcare costs and social burdens. It also disproportionately affects low-income and less-healthy people.

Objectives

This study examines the associations of chronic back pain with biological, psychological, and social factors; how it limits usual activities; and how chronic back pain influences the use of treatment services.

Methods

Using Brazil’s National Health Survey (PNS-2019), multivariate logistic regressions were conducted to examine how biological, psychological, and social factors correlate with chronic back pain, limitations on usual activities, and pain treatment.

Results

PNS-2019 data showed that 23.4% (95% CI 22.8–24.0) of Brazilian adults aged over 20 reported back pain. A higher prevalence of chronic back pain was associated with biological factors (older age, being female, overweight or obese, current smoking, and having more chronic conditions), lower social conditions (low education, low per capita household income, non-married, and living in rural areas), and poor psychological health (more depressive symptoms). Chronic back pain is more likely to limit usual activities among those with low social conditions (lower education, lower income), poor physical and behavioral health (obese, current smokers, and those with a greater number of chronic conditions), and worse psychological health (more depressive symptoms). However, married people and those who do not consume alcohol were also more likely to report limited activities. Among those with back pain, 68% received at least one form of treatment. Those with intense limitations on their usual activities were 2.2 times as likely to report treatment. People with higher social conditions (higher income, college education, and private health insurance) were more likely to receive treatment.

Conclusion

The results show significant biological, psychological, and social disparities in the prevalence of chronic back pain in Brazil. The findings point to the need for tailored policies and prevention programs with attention to vulnerable groups. Even though Brazil has universal health care, those with better socioeconomic conditions are more likely to receive treatment.
