[PMID: 39116059 PMCID: PMC11309383 DOI: 10.1371/journal.pone.0306993] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2024] [Accepted: 06/25/2024] [Indexed: 08/10/2024] Open
Abstract
BACKGROUND Musculoskeletal (MSK) spinal pain encapsulates various conditions including lumbar (low back), cervical (neck), and thoracic pain that significantly impact individual and global health. While clinical aspects of spinal pain have been well-studied, understanding patients' personal narratives and lived experiences remains essential for enhancing patient-centered care, improving treatment adherence, and informing healthcare policies. It provides deep insights into the impacts of spinal pain, guiding more effective and empathetic treatment approaches. This systematic review aims to synthesize qualitative evidence on patients' experiences with MSK spinal pain, providing insight into the challenges faced, coping strategies, daily life impacts, and healthcare interactions. The objective of this review is to synthesize the qualitative evidence regarding the lived experiences of patients with MSK spinal pain. METHODS This systematic review will use a meta-aggregation approach to synthesize data from qualitative studies, that will be identified through a comprehensive search of electronic databases and supplemented by grey literature searches. Two independent reviewers will screen, identify, and extract data from eligible studies. In cases of disagreement, conflicts will be resolved by consulting a third reviewer. These same reviewers will then use the Joanna Briggs Institute (JBI) qualitative quality assessment tool to evaluate the methodological quality of the identified studies, with the derived scores informing the synthesis process, that will involve extracting each study's findings along with their supporting illustrations, then grouped into categories based on similarity in meaning. These categories will then be aggregated to form synthesized findings. IMPLICATIONS Synthesized findings on patients' lived experiences with MSK spinal pain including key themes, patterns, and insights will be presented. By emphasizing patient narratives, the results of the review can contribute to the optimization of outcomes, and to enhance patient-provider relations and improve quality of care in MSK spinal health.

Abstract
Objective We present a general framework of simultaneous needle shape reconstruction and control input generation for robot-assisted spinal injection procedures, without continuous imaging feedback. Methods System input-output mapping is generated with a real-time needle-tissue interaction simulation, and single-core FBG sensor readings are used as local needle shape feedback within the same simulation framework. FBG wavelength shifts due to temperature variation is removed by exploiting redundancy in fiber arrangement. Results Targeting experiments performed on both plastisol lumbar phantoms as well as an ex vivo porcine lumbar section achieved in-plane tip errors of 0.6 ± 0.3 mm and 1.6 ± 0.9 mm , and total tip errors of 0.9 ± 0.7 mm and 2.1 ± 0.8 mm for the two testing environments. Significance Our clinically inspired control strategy and workflow is self-contained and not dependent on the modality of imaging guidance. The generalizability of the proposed approach can be applied to other needle-based interventions where medical imaging cannot be reliably utilized as part of a closed-loop control system for needle guidance.

Abstract
OBJECTIVE: To examine the associations between (i) various types of physical activity and the risk of back pain incidence, and (ii) the influence of substituting sedentary behaviours with physical activities on back pain incidence. DESIGN: A prospective cohort study. METHODS: We analyzed UK Biobank data collected from 365,307 participants who were free of back pain at baseline. The exposures were total, light, moderate and vigorous physical activity, and sedentary behaviours. The outcome was back pain incidence. The main statistical models were the Cox proportional hazard model and the isotemporal substitution model. RESULTS: In the follow-up time (median, 12.97 years; inter-quartile range, 12.10-13.71), 25,189 individuals developed back pain. The associations between all types of physical activity and incident back pain were significantly non-linear (p < 0.001) among the general population and other subgroups. High physical activity was associated with a decreased risk of back pain compared with no physical activity. The lowest risk occurred in the 1801-2400 MET-min/week subgroup of total physical activity (HR 0.64, 95% CI 0.59-0.69), approximately consisting of 1200, 600, and 600 MET-min/week of light, moderate and vigorous physical activity, respectively. Extremely high vigorous physical activity was related to high risk, specifically in males (HR 1.13, 95% CI 1.02-1.25). Replacing 1 hour/day of sedentary behaviours with an equal time of physical activity reduced the risk of incident back pain by 2%-8% (p < 0.05). CONCLUSION: Physical activity was related to a reduced risk of back pain incidence (except over-high vigorous physical activity). Substituting sedentary behaviours with physical activities reduced the risk of future back pain.

Front Public Health 2024; 12:1400312. [PMID: 38835612 PMCID: PMC11148220 DOI: 10.3389/fpubh.2024.1400312] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2024] [Accepted: 04/30/2024] [Indexed: 06/06/2024] Open
Abstract
Background Work-related musculoskeletal disorders are widespread among workers of informal small-scale enterprises. Specifically, lower back pain is a prevalent occupational health problem across various industries, including weaving factories. Lower back pain significantly impairs the functioning, performance, and productivity of weavers. However, information on the prevalence and associated factors of low back pain among weavers of Bahir Dar City and nationwide is scarce. Therefore, this study aimed to assess the prevalence and associated factors of lower back pain among weavers working in Bahir Dar City. Method A multicentered institutional-based cross-sectional study was conducted on 403 weavers in Bahir Dar City, Ethiopia, from April to May 2023 using a structured face-to-face interview questionnaire. Samples were proportionally allocated to each institution, and study participants were selected using a simple random sampling technique. Variables with a P-value < 0.25 in the bivariate logistic regression were adopted for the multivariate logistic regression analysis after verifying the model fitness. In the multivariate logistic regression analysis, the adjusted odds ratio (AOR) with a 95% confidence interval (CI) and a P-value < 0.05 were considered to identify the associated factors of lower back pain among weavers. Result The results revealed that the overall annual prevalence of lower back pain was 63.5% (95% CI = 58.8-68.5). Longer working hours [AOR = 2.580 (CI = 1.517-4.384)], lack of back support [AOR = 1.938 (CI = 2.089-3.449)], repetitive movement of the back during weaving [AOR = 5.940 (CI = 2.709-13.02)], awkward posture [AOR = 2.915 (CI = 1.677-5.065), static working posture [AOR = 4.505 (CI = 2.298-8.831)], and job stress [AOR = 3.306 (CI = 1.896-5.765)] were significantly associated with lower back pain among weavers. Conclusions Lower back pain among weavers was found to be highly prevalent. Working longer hours, lack of back support, repetitive movement of the back, awkward posture, static posture, and job stress were significantly associated with lower back among weavers. The study recommends prompt interventions on weavers to ensure that they use sitting support, weave for <8 h per day, change positions every 2 h, reduce job-related stress, and minimize task repetition, thereby enhancing their working conditions and minimizing the occurrence of lower back pain.

The chiropractors' dilemma in caring for older patients with musculoskeletal complaints: Collaborate, integrate, coexist, or separate? PLoS One 2024; 19:e0302519.

Abstract
The world's elderly population is growing at a rapid pace. This has led to an increase in demand on the health and welfare systems due to age-related disorders, with musculoskeletal complaints driving the need for rehabilitation services. However, there are concerns about health services' ability to meet this demand. While chiropractic care is gaining recognition for its benefits in treating older adults with musculoskeletal disorders, there is limited scientific literature on chiropractors' role and experiences in this area. To bridge this gap, we interviewed 21 chiropractors in Great Britain, the Netherlands, Norway, and Sweden. Inductive qualitative content analysis was used to analyse the interviews, and despite differences in integration and regulation between the countries, several common facilitators and barriers in caring for and managing older patients with musculoskeletal complaints emerged. While participants expressed optimism about future collaborations with other healthcare professionals and the integration of chiropractic into national healthcare systems, they also highlighted significant concerns regarding the existing healthcare infrastructure. The participants also felt that chiropractors, with their non-surgical and holistic approach, were well-positioned to be the primary point of contact for older patients. However, there were some common barriers, such as the affordability of care, limited integration of chiropractic, and the need to prioritise musculoskeletal complaints within public healthcare. Our findings suggest that chiropractors experience their clinical competencies as an underutilised resource in the available healthcare systems and that they could contribute to and potentially reduce the escalating burden of musculoskeletal complaints and associated costs among older patients. Additionally, our findings highlight the desire among the participants to foster collaboration among healthcare professionals and integrate chiropractic into the national public healthcare system. Integrating chiropractors as allied health professionals was also perceived to improve coordinated, patient-centred healthcare for older adults.

Abstract
BACKGROUND Psychosocial factors and alteration of the somatosensory functions have been associated with persistent low back pain (LBP). A decreased capacity of the central nervous system to modulate pain has been suggested as a potential contributor to the persistence of pain. OBJECTIVE To investigate whether conditioned pain modulation (CPM), initial symptoms/disability, kinesiophobia, and pain catastrophizing is associated with the transition from acute to chronic LBP. DESIGN Prospective cohort study. METHOD Fifty participants presenting with acute LBP (<6 weeks) took part in three evaluation sessions (baseline, 3 and 6 months). At baseline and 3-month evaluations, all participants completed self-administered questionnaires (Oswestry Disability Index [ODI], Short Form of Brief Pain Inventory [BPI-SF], Tampa Scale of Kinesiophobia [TSK] and Pain Catastrophizing Scale [PCS]) and CPM was assessed. At the 6-month evaluation, questionnaires were readministered, and participants were dichotomized according to their status (Non-chronic LBP [NCLBP] or chronic LBP [CLBP]). Univariate tests were used to compare baseline variables between NCLBP and CLBP. RESULTS No significant baseline difference was found for TSK (p = 0.48), PCS (p = 0.78), CPM (p = 0.82), ODI (p = 0.78), BPI-SF severity (p = 0.50), and interference subscales (p = 0.54) between those categorized as NCLBP or CLBP at 6 months. CONCLUSIONS This exploratory study failed to support the hypothesis that inefficient CPM mechanisms and the presence of psychological factors could be factors associated with the transition to chronic pain in individuals with acute LBP.

Abstract
Background Neck pain (NP) is a condition influenced by multiple factors. It places a significant burden on individuals suffering from NP and on social and economic systems. On a global scale, low back pain (LBP) stands out as a significant contributor to years lost to disability, and this burden is on the rise due to population growth and aging. Methods The Global Burden of Disease database was used to collect data on the prevalence, incidence, and years lived with disability (YLD) of NP and LBP between 1990 and 2019. Various factors, including age group, gender, Iran, and its 31 provinces, were used to classify the data. Results Iran accounted for 0.86 million incident cases of NP in 2019, with age-standardized incident rate per 100 000 population of 934.1. Tehran has the maximum age-standardized prevalence, incidence, and YLD. Iran accounted for the age-standardized incidence rate for LBP per 100 000 population of 3492.9, and it reduced to -8.35% from 1990. Mazandaran exhibits the highest levels of prevalence, incidence, and YLD for LBP in 2019. In Iran, the point prevalence of NP in 2019 was higher in females and increased with age up to 50-54 years for females and 70-74 years for males. However, there is only a slight difference between females and males in Iran regarding LBP prevalence. Conclusions In this study, the authors report the prevalence, incidence, YLD, and age-standardized rates for NP and LBP in the world's general population and Iran's population based on its sub-nations in 1990 and 2019.

Abstract
STUDY DESIGN A prospective study. OBJECTIVES This study aims to explore the correlation between interleukin (IL)- 6 levels in intervertebral disc (IVD) tissue and clinical outcomes in patients undergoing lumbar surgery for lumbar degenerative disease (LDD). METHODS This prospective study analyzed 32 patients (22 men and 10 women, average age 69.6 years) who underwent lateral lumbar interbody fusion (LLIF). IL-6 gene expression in IVD tissues collected during surgery was measured and correlated with pre- and postoperative clinical outcomes, including pain intensity assessed via Numeric Rating Scales (NRS) and quality of life (QOL) evaluated through the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ). RESULTS IL-6 levels showed statistical correlations with postoperative intensity of low back pain (LBP) and several JOABPEQ domains. Patients with higher expression of IL-6 levels experienced more severe postoperative LBP and lower scores in lumbar function, walking ability, social life function, and mental health. The effectiveness rate of JOABPEQ scores was exceptionally high for low back pain (.548), walking ability (.677), and social functioning (.563), demonstrating the effectiveness of LLIF. The average operation time was 105.6 minutes, and the estimated blood loss was 85.6 mL. CONCLUSIONS The study underscores IL-6 as a potential biomarker for predicting surgical outcomes in LDD. High IL-6 levels correlate with worse postoperative LBP and lower QOL scores. Integrating molecular markers like IL-6 with patient-reported outcomes could provide a more comprehensive approach to postoperative care in spinal disorders, aiming to improve the overall QOL for LDD patients undergoing LLIF surgery.

Abstract
INTRODUCTION Data on the Medicare-aged population show that older patients are major consumers of low back pain (LBP) interventions. An effective approach for patients with mechanical LBP that has been refractory to conservative management is restorative neurostimulation. The efficacy of restorative neurostimulation has been demonstrated in multiple prospective studies, with published follow-up over 4 years, showing a consistent durable effect. METHODS To further examine the effect of restorative neurostimulation in an older demographic, data from three clinical studies were aggregated: ReActiv8-B prospectively followed 204 patients, ReActiv8-C study prospectively followed 87 patients and ReActiv8-PMCF prospectively followed 42 patients.Two hundred and sixty-one patients were identified with complete 2-year follow-up and divided into cohorts of equal size based of age quartiles.At 2 years from device activation, patients in either cohort were classified by change in disability (Oswestry Disability Index (ODI)) or change in pain score(NRS/VAS) and assessed as proportion of patients per group at each time point. Additionally, health-related quality of life (HRQoL) (EQ5D-5L) was longitudinally compared with baseline. Differences in proportions were assessed using χ2 and continuous variables by repeated measures analysis of variance. RESULTS The oldest quartile (n=65) had a median age of 60 (56-82) years compared with the entire population (n=261) who had a median age of 49 (22-82) years. The completer analysis on patients with 2 years of continuous data showed improvement of a 50% in pain was achieved by 62% and 65% and a 15-point ODI improvement in 48% and 60% in the oldest quartile and entire population, respectively. HRQoL (EuroQol 5-Dimension) improved from baselines of 0.568 and 0.544 to 0.763 and 0.769 in the oldest quartile and entire population respectively. All age quartiles improved statistically and clinically over baseline. CONCLUSIONS This aggregate analysis of three independent studies provides insight into the performance of restorative neurostimulation in an older population. Patients derived significant and clinically meaningful benefit in disability, pain and HRQoL. When compared with a similarly indicated cohort of younger patients, there were no statistically or clinically significant differences.

Abstract
OBJECTIVE The purpose of this study was to evaluate the feasibility of a randomized controlled trial investigating the effectiveness of a multimodal program (PAT-Back) compared to best practice advice on pain and disability in older adults with chronic low back pain (LBP) in primary care. METHODS This feasibility study took place in Fortaleza, Northeast Brazil. The PAT-Back intervention consisted of a program including exercises, pain education, and motivational text messages for the in-home component. The control group received an evidence-based educational booklet. Feasibility outcomes were recruitment, adherence and retention rates, level of difficulty of the education and intervention content, perception of utility of mobile technology, and adverse events. The feasibility criteria were previously defined. RESULTS A total of 248 people were screened, of which 46 older adults were eligible. The retention rate was high (100% in the PAT-Back group and 95% in the control group). The adherence rate to intervention was partially met (60%), whereas the adherence rate to unsupervised exercises was adequate (75%), and perception about safety to perform home exercise was partially acceptable (70%) in the PAT-Back group. In addition, 100% of older adults reported which text messages motivated them to perform the exercises in the PAT-Back group. Difficulty reported by participants in understanding and performing the intervention was small in both groups. Six participants reported transient adverse events in both groups. CONCLUSION Older adults accepted both interventions. Results demonstrated that the program is feasible, although minor changes targeting adherence and safety in home exercise are needed. IMPACT This feasibility study supports progression to a full trial investigating the effectiveness of a multimodal program (PAT-Back) on pain and disability in older adults with chronic LBP within a primary health care setting in low to middle income countries where such data from the older population are scarce and the burden of LBP is increasing.

Identifying latent subgroups in the older population seeking primary health care for a new episode of back pain - findings from the BACE-N cohort. BMC Musculoskelet Disord 2024; 25:60.

Abstract
BACKGROUND Back pain is the number one condition contributing to years lived with disability worldwide, and one of the most common reasons for seeking primary care. Research on this condition in the ageing population is sparse. Further, the heterogeneity of patients with back pain complicates the management in clinical care. It is possible that subgrouping people with similar characteristics would improve management. This paper aimed to identify latent classes based on demographics, pain characteristics, psychosocial behavior, and beliefs and attitudes about back pain, among older patients seeking primary care with a new episode of back pain, and to examine if there were differences regarding the classes' first point-of-contact. METHODS The study was part of the international BACE (Back complaints in elders) consortium and included 435 patients aged ≥ 55 years seeking primary care (general practitioners, physiotherapists, and chiropractors) in Norway from April 2015 to March 2020. A latent class analysis was performed to identify latent classes. The classes were described in terms of baseline characteristics and first point-of-contact in primary care. RESULTS Four latent classes were identified. The mean age was similar across groups, as were high expectations towards improvement. Class 1 (n = 169, 39%), the "positive" class, had more positive attitudes and beliefs, less pain catastrophizing and shorter duration of current pain episode. Class 2 (n = 31, 7%), the "fearful" class, exhibited the most fear avoidance behavior, and had higher mean pain intensity. Class 3 (n = 33, 8%), the "distressed" class, had the highest scores on depression, disability, and catastrophizing. Finally, class 4 (n = 202, 46%), the "hopeful" class, showed the highest expectations for recovery, although having high pain intensity. The identified four classes showed high internal homogeneity, sufficient between-group heterogeneity and were considered clinically meaningful. The distribution of first point-of-contact was similar across classes, except for the positive class where significantly more patients visited chiropractors compared to general practitioners and physiotherapists. CONCLUSIONS The identified classes may contribute to targeting clinical management of these patients. Longitudinal research on these latent classes is needed to explore whether the latent classes have prognostic value. Validation studies are needed to evaluate external validity.

Perturbation-based Balance Training in Adults Aged Above 55 Years with Chronic Low Back Pain: A Comparison of Effects of Water versus Land Medium - A Preliminary Randomized Trial. Curr Aging Sci 2024; 17:156-168. [PMID: 38111118 DOI: 10.2174/0118746098254991231125143735] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Revised: 07/16/2023] [Accepted: 10/23/2023] [Indexed: 12/20/2023]
Abstract
BACKGROUND 'Rapid balance reaction' or 'perturbation' training is an emerging paradigm in elderly back pain rehabilitation due to its connection to postural stability. OBJECTIVE This study aimed to inform the feasibility and practicality of perturbation-based balance training (PBT) using a stratification approach and to determine the effectiveness of land versus water-based PBT in elderly individuals with chronic low back pain (CLBP). METHODS Elderly CLBP participants (n=24) received exercise interventions as per treatmentbased classification (TBC) and were randomly allotted into water-based perturbation exercises (WBPE, Mean age=63.0±2.6years, n=12) and land-based perturbation exercise group (LBPE, 62.3±2.6 years, n=12). Pain intensity, disability, scores of fear-avoidance beliefs, fall efficacy, and rate of perceived exertion (RPE) were assessed before and at the end of 6 weeks. RESULTS WBPE group reported a significant reduction in pain score (median difference(MD)):2, p<0.03), fear avoidance behaviour for work (MD:9, p<0.01) and fear avoidance behaviour for physical activity (MD:10, p< 0.05), improved straight leg raise right (SLR) (MD:37.5°, p<0.05), and improved modified fall efficacy scores (MFES, MD:25, p<0.05) compared to the LBPE group at post-intervention. Within-group analysis in both groups revealed significant improvement in clinical outcomes except for fear-avoidance beliefs related to physical activity in the LBPE group. Subgroup analysis revealed that the high BMI elderly CLBP group of LBPE had significant improvements similar to the WBPE group except for scores of FABQ physical activity scores and SLR. CONCLUSION Possible key factors for future research are discussed in the realms of perturbation exercise in the elderly with CLBP.

External validation and updating of prognostic prediction models for nonrecovery among older adults seeking primary care for back pain. Pain 2023; 164:2759-2768.

Abstract
ABSTRACT Prognostic prediction models for 3 different definitions of nonrecovery were developed in the Back Complaints in the Elders study in the Netherlands. The models' performance was good (optimism-adjusted area under receiver operating characteristics [AUC] curve ≥0.77, R2 ≥0.3). This study aimed to assess the external validity of the 3 prognostic prediction models in the Norwegian Back Complaints in the Elders study. We conducted a prospective cohort study, including 452 patients aged ≥55 years, seeking primary care for a new episode of back pain. Nonrecovery was defined for 2 outcomes, combining 6- and 12-month follow-up data: Persistent back pain (≥3/10 on numeric rating scale) and persistent disability (≥4/24 on Roland-Morris Disability Questionnaire). We could not assess the third model (self-reported nonrecovery) because of substantial missing data (>50%). The models consisted of biopsychosocial prognostic factors. First, we assessed Nagelkerke R2 , discrimination (AUC) and calibration (calibration-in-the-large [CITL], slope, and calibration plot). Step 2 was to recalibrate the models based on CITL and slope. Step 3 was to reestimate the model coefficients and assess if this improved performance. The back pain model demonstrated acceptable discrimination (AUC 0.74, 95% confidence interval: 0.69-0.79), and R2 was 0.23. The disability model demonstrated excellent discrimination (AUC 0.81, 95% confidence interval: 0.76-0.85), and R2 was 0.35. Both models had poor calibration (CITL <0, slope <1). Recalibration yielded acceptable calibration for both models, according to the calibration plots. Step 3 did not improve performance substantially. The recalibrated models may need further external validation, and the models' clinical impact should be assessed.

Abstract
Purpose Chronic low back pain (CLBP) is an aging and public health issue that is a leading cause of disability worldwide and has a significant economic impact on a global scale. Treatments for CLBP are varied, and there is currently no study with high-quality evidence to show which treatment works best. Exercise therapy has the characteristics of minor harm, low cost, and convenient implementation. It has become a mainstream treatment method in clinics for chronic low back pain. However, there is insufficient evidence on which specific exercise regimen is more effective for chronic non-specific low back pain. This network meta-analysis aimed to evaluate the effects of different exercise therapies on chronic low back pain and provide a reference for exercise regimens in CLBP patients. Methods We searched PubMed, EMBASE, Cochrane Library, and Web of Science from inception to 10 May 2022. Inclusion and exclusion criteria were used for selection. We collected information from studies to compare the effects of 20 exercise interventions on patients with chronic low back pain. Results This study included 75 randomized controlled trials (RCTs) with 5,254 participants. Network meta-analysis results showed that tai chi [standardized mean difference (SMD), -2.11; 95% CI, -3.62 to -0.61], yoga (SMD, -1.76; 95% CI -2.72 to -0.81), Pilates exercise (SMD, -1.52; 95% CI, -2.68, to -0.36), and sling exercise (SMD, -1.19; 95% CI, -2.07 to -0.30) showed a better pain improvement than conventional rehabilitation. Tai chi (SMD, -2.42; 95% CI, -3.81 to -1.03) and yoga (SMD, -2.07; 95% CI, -2.80 to -1.34) showed a better pain improvement than no intervention provided. Yoga (SMD, -1.72; 95% CI, -2.91 to -0.53) and core or stabilization exercises (SMD, -1.04; 95% CI, -1.80 to -0.28) showed a better physical function improvement than conventional rehabilitation. Yoga (SMD, -1.81; 95% CI, -2.78 to -0.83) and core or stabilization exercises (SMD, -1.13; 95% CI, -1.66 to -0.59) showed a better physical function improvement than no intervention provided. Conclusion Compared with conventional rehabilitation and no intervention provided, tai chi, toga, Pilates exercise, sling exercise, motor control exercise, and core or stabilization exercises significantly improved CLBP in patients. Compared with conventional rehabilitation and no intervention provided, yoga and core or stabilization exercises were statistically significant in improving physical function in patients with CLBP. Due to the limitations of the quality and quantity of the included studies, it is difficult to make a definitive recommendation before more large-scale and high-quality RCTs are conducted.

Abstract
BACKGROUND The purpose of this network meta-analysis (NMA) is to investigate the efficacy of pharmacological and non-pharmacological therapy on pain intensity and disability of older people with chronic nonspecific low back pain, providing comprehensive evidence for an informed decision-making. METHODS We will perform a systematic search to identify randomized controlled trials of pharmacological and non-pharmacological interventions for older people with chronic nonspecific low back pain. MEDLINE, Cochrane Library, Embase, AMED, PsycINFO, and PEDro will be searched without language or date restrictions. Our primary outcomes are pain intensity and disability. Risk of bias will be assessed for all studies using the revised Cochrane risk-of-bias (RoB) tool 2.0. For each pairwise comparison between the different interventions, estimated mean differences and their 95% confidence intervals will be presented. Standard pairwise meta-analyses will be performed using random effects models in STATA version 16. The competing interventions will be ranked using the surface under the cumulative ranking curve (SUCRA) for the outcomes of interest at short and long terms. The confidence in the results from NMA will be assessed using the Confidence in Network Meta-Analysis (CINeMA) framework. DISCUSSION This NMA compares efficacy of interventions for nonspecific chronic low back pain in older people. It will provide reliable evidence for patients, clinicians, stakeholders, and researchers in this field where competing therapies, many of extraordinarily little value, are commonly used in clinical practice.

The Efficacy and Feasibility of an Interoceptive Exposure Technique for Preventing the Transition From Subacute to Chronic Back Pain by Altering the Emotional Response to Pain: Protocol for a Pilot Randomized Controlled Trial. JMIR Res Protoc 2023; 12:e45701. [PMID: 37856182 PMCID: PMC10623225 DOI: 10.2196/45701] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2023] [Revised: 08/16/2023] [Accepted: 09/04/2023] [Indexed: 10/20/2023] Open
Abstract
BACKGROUND Psychological factors such as stress, anxiety, mood, emotions, cognitive functioning, and pain behavior are relevant to the onset of pain and its continuation in the transition to chronic conditions. Subacute low back pain (LBP), a precursor to chronic LBP, is particularly poorly understood, and its relationships with psychological factors are understudied. OBJECTIVE We will conduct a study aiming to prevent the chronicity of subacute LBP by altering the emotional response to pain using an interoceptive exposure technique (IET). Considering the recent increase in knowledge about psychological risk factors, as well as recent findings in cognitive neuroscience regarding emotional and cognitive background factors in the LBP chronicity process, efforts should be made to discover effective preventive methods. METHODS We present a novel method aiming to prevent the transition from subacute to chronic back pain by altering the emotional response to pain using an IET. In this pilot randomized controlled trial, participants who are at a higher risk of LBP chronification due to the presence of a biomarker (ie, functional connectivity between the medial prefrontal cortex and nucleus accumbens) will be randomly assigned to the IET intervention group or control group A (treatment as usual). Participants who do not present with the biomarker will be assigned to control group B (treatment as usual) to assess how well this biomarker predicts the chronification of subacute LBP in this study population. Questionnaires measuring the pain experience and psychological distress will be used before the intervention, after the intervention (at 3 months), and at the 12-month follow-up. RESULTS This research project will combine 2 novel methods: a biomarker as the inclusion criterion and an IET as the intervention. The comparative study design enables evaluation of the efficacy of the IET, as well as replication of the biomarker's validity as a possible clinical screening method. CONCLUSIONS If found to be useful, the IET would offer a cost-effective and reasonable way to develop treatment for acute and subacute back pain conditions. Potential benefits include increased pain management and quality of life for the individual patient with the addition of a potentially useful functional pain management method at the societal level.

Abstract
The aim was to identify factors, which may affect the relationship between physical activity and pain severity among patients with low back pain (LBP). It was a cross-sectional survey-based study among 1332 consecutive patients with LBP. Linear regression models were employed. Patients were 47.6 years old and 64% were women. For the entire sample, pain severity and the intensity of physical activity were negatively associated. Higher physical activity was associated with younger age, higher educational level, normal weight and optimal perceived general health. Sex, smoking, marital status and occupation did not demonstrate significant interactions on the association. The severity of disability showed paradoxical effect on the relationship between pain and physical activity - severe disability was associated with increase in physical activity.

Abstract
BACKGROUND AND PURPOSE The aim of the present systematic review was to investigate the effectiveness of pharmacological and non-pharmacological therapy on pain intensity and disability in older people with chronic nonspecific low back pain. METHODS Searches were conducted in the MEDLINE, COCHRANE LIBRARY, EMBASE, AMED, PSYCINFO, and PEDRO databases up to 2022. Risk of bias was appraised using the Cochrane Risk of Bias 2.0 tool. Estimated mean differences and respective 95% confidence intervals were presented for each paired comparison and the strength of the current evidence was assessed using the GRADE approach. RESULTS AND DISCUSSION Thirty-one original trials involving 2120 participants were included. All outcomes were self-rated. Pain intensity was measured using the Visual Analogue Scale or Numerical Rating Scale. Disability was evaluated using the Roland Morris Disability Questionnaire, Oswestry Disability Index or Hannover Functional Ability Questionnaire. Short-term: Moderate quality of evidence that mindfulness reduces disability compared to patient education (mean difference [MD] = - 1.38 [95% CI - 2.02 to - 0.73]); low-quality evidence that mixed exercise (MD = - 50.33 [95% CI - 57.11 to - 43.56]) reduces pain compared to no intervention, waiting list, placebo or sham; low quality of evidence that there is no effect for opioid compared to placebo (MD = - 8.26 [95% CI - 19.29 to 2.77]) with regards to reducing pain and opioid/acetaminophen reduces disability more compared to pregabalin (MD = 2.36 [95% CI] 1.86-2.86]). CONCLUSIONS The findings showed low or very low quality of evidence for non-pharmacological interventions with a large effect in short- and long-term follow-up. The two studies that provided moderate quality of evidence had a small clinical effect. Only two studies were found that investigated pharmacological therapies-both with low quality of evidence. However, the studies were methodologically weak and had small sample sizes. Given the adverse effects of low back pain and the scarce information on the effectiveness of pharmacological and non-pharmacological treatments for older people, future randomized trials should be encouraged.

Abstract
Objective To investigate the differences between erector spinae muscle activation in healthy individuals and patients with Chronic Lower Back Pain (CLBP) by conducting (a) systematic review and (b) meta-analysis. Data Sources PubMed, ScienceDirect, SPORTDiscus, and Google Scholar were used to conduct the searches, which included studies up to the 31st of March 2023 with no start date specified. Study Selection Any study otherwise meeting eligibility criteria was included if it reported either (1) a standard mean difference effect size; or (2) the means, SDs, and sample sizes for both the patient group and the comparator group. Data Extraction A total of 7 case control trials were used for the systematic review and meta-analysis. Data Synthesis The systematic review and meta-analysis revealed that total standardized mean difference in erector spinae muscle activation between healthy individuals vs patients with CLBP expressed in % maximum voluntary isometric contraction was 0.48 (95% confidence interval=0.21-0.74; P<.001) with the heterogeneity being I2=0% (P=.890). The electromyography (EMG) outputs showed significant differences in activation levels between the healthy and CLBP cohorts (P<.001). Conclusions A small effect size was found in the meta-analysis. The muscle activation levels of the erector spinae during forward propulsion were higher in CLBP individuals compared with healthy cohorts. The findings provide more clarity about the muscles that were the focus of previous research, what procedures were used to evaluate muscular contributions and what speeds the participants were moving at during the test sessions. Given the limited methodological quality of the included studies, the findings should be interpreted with caution. Future research should evaluate the effect of other factors such as walking distance and any changes in walking surfaces and gradients (ie, non-flat surfaces).

Abstract
BACKGROUND Although the association between multimorbidity (MM) and hospitalisation is known, the different effects of MM patterns by age and sex in this outcome needs to be elucidated. Our study aimed to analyse the association of hospitalisations' variables (occurrence, readmission, length of stay) and patterns of multimorbidity (MM) according to sex and age. METHODS Data from 8.807 participants aged ≥ 50 years sourced from the baseline of the Brazilian Longitudinal Study of Ageing (ELSI-Brazil) were analysed. Multimorbidity was defined as ≥ 2 (MM2) and ≥ 3 (MM3) chronic conditions. Poisson regression was used to verify the association between the independent variables and hospitalisation according to sex and age group. Multiple linear regression models were constructed for the outcomes of readmission and length of stay. Ising models were used to estimate the networks of diseases and MM patterns. RESULTS Regarding the risk of hospitalisation among those with MM2, we observed a positive association with male sex, age ≥ 75 years and women aged ≥ 75 years. For MM3, there was a positive association with hospitalisation among males. For the outcomes hospital readmission and length of stay, we observed a positive association with male sex and women aged ≥ 75 years. Network analysis identified two groups that are more strongly associated with occurrence of hospitalisation: the cardiovascular-cancer-glaucoma-cataract group stratified by sex and the neurodegenerative diseases-renal failure-haemorrhagic stroke group stratified by age group. CONCLUSION We conclude that the association between hospitalisation, readmission, length of stay, and MM changes when sex and age group are considered. Differences were identified in the MM patterns associated with hospitalisation according to sex and age group.

Abstract
Objective Posttraumatic stress disorder (PTSD) symptoms and pain interfere with daily functioning and quality of life for many combat Veterans. As individuals age, pain symptoms tend to increase whereas PTSD symptoms tend to decrease. PTSD symptoms exacerbate pain, but the nature of this relationship across the aging process is unclear. The purpose of this study was to determine how PTSD symptoms affect the association between age and pain intensity. Methods Participants in this cross-sectional study included 450 Veterans (80% male) who served after September 11, 2001. PTSD and pain intensity ratings were assessed by the PTSD Checklist for DSM-5 (PCL-5) and the Brief Pain Inventory (BPI), respectively. Hierarchical multiple linear regression evaluated main and interaction effects between age, PTSD symptoms, and pain intensity. Results Age (B = 0.04, p < 0.001) and PTSD symptoms (B = 0.05, p < 0.001) were positively associated with pain intensity. Age and PTSD symptoms were inversely correlated (r = -0.16, p < 0.001). PTSD symptoms exacerbated the relationship between age and pain intensity (ΔR2 = 0.01, p = 0.036). Specifically, when greater PTSD symptoms were reported at older ages, pain intensity was significantly higher. Conclusion Results of these analyses suggests that age is important when considering the effects of PTSD symptoms on pain intensity ratings. Specifically, pain intensity ratings are higher in older Veterans with PTSD symptoms. These findings underscore the importance for clinical providers to evaluate trauma history and PTSD symptoms in older Veterans reporting pain symptoms.

Abstract
Introduction Low back pain (LBP) is a common health problem, and the leading cause of activity limitation and work absence among people of all ages and socioeconomic strata. This study aimed to analyse the clinical and economic burden of LBP in high income countries (HICs) via systematic review and meta-analysis. Methods A literature search was carried out on PubMed, Medline, CINAHL, PsycINFO, AMED, and Scopus databases was from inception to March 15th, 2023. Studies that assessed the clinical and economic burden of LBP in HICs and published in English language were reviewed. The methodological quality of the included studies was assessed using the Newcastle-Ottawa quality assessment scale (NOS) for cohort studies. Two reviewers, using a predefined data extraction form, independently extracted data. Meta-analyses were conducted for clinical and economic outcomes. Results The search identified 4,081 potentially relevant articles. Twenty-one studies that met the eligibility criteria were included and reviewed in this systematic review and meta-analysis. The included studies were from the regions of America (n = 5); Europe (n = 12), and the Western Pacific (n = 4). The average annual direct and indirect costs estimate per population for LBP ranged from € 2.3 billion to € 2.6 billion; and € 0.24 billion to $8.15 billion, respectively. In the random effects meta-analysis, the pooled annual rate of hospitalization for LBP was 3.2% (95% confidence interval 0.6%-5.7%). The pooled direct costs and total costs of LBP per patients were USD 9,231 (95% confidence interval -7,126.71-25,588.9) and USD 10,143.1 (95% confidence interval 6,083.59-14,202.6), respectively. Discussion Low back pain led to high clinical and economic burden in HICs that varied significantly across the geographical contexts. The results of our analysis can be used by clinicians, and policymakers to better allocate resources for prevention and management strategies for LBP to improve health outcomes and reduce the substantial burden associated with the condition.

Abstract
Background Low back pain is highly prevalent and the main cause of years lived with disability (YLDs). We present the most up-to-date global, regional, and national data on prevalence and YLDs for low back pain from the Global Burden of Diseases, Injuries, and Risk Factors Study 2021. Methods Population-based studies from 1980 to 2019 identified in a systematic review, international surveys, US medical claims data, and dataset contributions by collaborators were used to estimate the prevalence and YLDs for low back pain from 1990 to 2020, for 204 countries and territories. Low back pain was defined as pain between the 12th ribs and the gluteal folds that lasted a day or more; input data using alternative definitions were adjusted in a network meta-regression analysis. Nested Bayesian meta-regression models were used to estimate prevalence and YLDs by age, sex, year, and location. Prevalence was projected to 2050 by running a regression on prevalence rates using Socio-demographic Index as a predictor, then multiplying them by projected population estimates. Findings In 2020, low back pain affected 619 million (95% uncertainty interval 554-694) people globally, with a projection of 843 million (759-933) prevalent cases by 2050. In 2020, the global age-standardised rate of YLDs was 832 per 100 000 (578-1070). Between 1990 and 2020, age-standardised rates of prevalence and YLDs decreased by 10·4% (10·9-10·0) and 10·5% (11·1-10·0), respectively. A total of 38·8% (28·7-47·0) of YLDs were attributed to occupational factors, smoking, and high BMI. Interpretation Low back pain remains the leading cause of YLDs globally, and in 2020, there were more than half a billion prevalent cases of low back pain worldwide. While age-standardised rates have decreased modestly over the past three decades, it is projected that globally in 2050, more than 800 million people will have low back pain. Challenges persist in obtaining primary country-level data on low back pain, and there is an urgent need for more high-quality, primary, country-level data on both prevalence and severity distributions to improve accuracy and monitor change.

Abstract
ABSTRACT Back pain and comorbidity are common in older adults. Comorbidity is a promising prognostic factor for the clinical course of back-related disability, but confirmatory studies assessing its prognostic value are needed. Thus, the aims of this study were to describe the clinical course of back-related disability during 1-year follow-up in patients aged ≥55 years visiting primary care (general practitioner, physiotherapist, or chiropractor) with a new episode of back pain and assess the prognostic value of comorbidity on back-related disability during 1-year follow-up. A prospective cohort study was conducted, including 452 patients. The outcome measure was Roland-Morris Disability Questionnaire (RMDQ, range 0-24) measured at baseline and at 3-, 6-, and 12-month follow-up. The Self-Administered Comorbidity Questionnaire was used to assess comorbidity count (CC, range 0-15) and comorbidity burden (CB, range 0-45). The RMDQ scores improved from median (interquartile range) 9 (4-13) at baseline to 4 (1-9), 4 (0-9), and 3 (0-9) at 3, 6, and 12 months, respectively. Using linear mixed-effects models, we found that CC and CB were independently associated with RMDQ scores. A 1-point increase in CC was associated with an increase in RMDQ score of 0.76 points (95% confidence interval [0.48-1.04]) over the follow-up year, adjusted for known prognostic factors. A 1-point increase in CB was associated with an increased RMDQ score of 0.47 points (95% confidence interval [0.33-0.61]). In conclusion, the clinical course of back-related disability for older adults presenting in primary care was favorable, and increased comorbidity was an independent prognostic factor for increased disability levels.

Abstract
ABSTRACT Conventional "1-variable-at-a-time" analyses to identify treatment effect modifiers are often underpowered and prone to false-positive results. This study used a "risk-modeling" approach guided by the Predictive Approaches to Treatment effect Heterogeneity (PATH) Statement framework: (1) developing and validating a multivariable model to estimate predicted future back-related functional limitations as measured by the Roland-Morris Disability Questionnaire (RMDQ) and (2) stratifying patients from a randomized controlled trial (RCT) of lumbar epidural steroid injections (LESIs) for the treatment of lumbar spinal stenosis into subgroups with different individualized treatment effects on RMDQ scores at the 3-week follow-up. Model development and validation were conducted in a cohort (n = 3259) randomly split into training and testing sets in a 4:1 ratio. The model was developed in the testing set using linear regression with least absolute shrinkage and selection regularization and 5-fold cross-validation. The model was then applied in the testing set and subsequently in patients receiving the control treatment in the RCT of LESI. R2 values in the training set, testing set, and RCT were 0.38, 0.32, and 0.34, respectively. There was statistically significant modification ( P = 0.03) of the LESI treatment effect according to predicted risk quartile, with clinically relevant LESI treatment effect point estimates in the 2 quartiles with greatest predicted risk (-3.7 and -3.3 RMDQ points) and no effect in the lowest 2 quartiles. A multivariable risk-modeling approach identified subgroups of patients with lumbar spinal stenosis with a clinically relevant treatment effect of LESI on back-related functional limitations.

Abstract
Abstract The article aims to estimate the incidence and worsening of back pain (BP) during the first wave of COVID-19 in Brazil, as well as to investigate demographic, socioeconomic factors and associated changes in living conditions. ConVid - Behavior Research, applied between April and May 2020, was used as data source. The number and distribution of respondents who developed BP and those who had a worsening of the preexisting problem, their 95% confidence intervals and Pearson’s Chi-square test were estimated. The odds ratio of developing BP or worsening a preexisting problem was also estimated using multiple logistic regression models. Pre-existing BP was reported by 33.9% (95%CI 32.5-35.3) of respondents and more than half (54.4%; 95%CI 51.9-56.9) had worsened. The cumulative incidence of BP in the first wave of the pandemic was 40.9% (95%CI 39.2-42.7). Being a woman, the perceived increase in housework and the frequent feeling of sadness or depression were associated with both outcomes. Socioeconomic factors were not associated with any of outcome. The high incidence and worsening of BP during the first wave reveal the need for studies in more recent periods, given the long duration of the pandemic.

J Pain Res 2023; 16:1169-1183. [PMID: 37064955 PMCID: PMC10095945 DOI: 10.2147/jpr.s401894] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2022] [Accepted: 03/14/2023] [Indexed: 04/18/2023] Open
Abstract
Background and Purpose Epidemiological studies on low back pain in residents living in mountainous areas are scarce. The study was aimed at investigating the prevalence and associated factors of low back pain in Chongqing, relatively impoverished mountainous areas of China. Materials and Methods This was a cross-sectional study conducted at selected community or village health service centers in Chongqing over a 2-month period (May 2021 to June 2021), which included adults of Chongqing aged >18 years with or without low back pain (N=1820) chosen by stratified, cluster-sampling. Associated factors of low back pain including sociodemographic characteristics, lifestyle, and occupational features were collected, along with medical history, Oswestry Disability Questionnaire (ODI), and Numerical Rating Scale (NRS) of patients with low back pain, and carried out for at least 20 minutes per respondent. Univariate and multivariate logistic regression models were utilized for statistical analysis. Results Overall, 30.5% of 1704 respondents presented with low back pain, with 26.3% living in flat areas and 35.6% in mountainous areas. The associated factors of low back pain were mountainous area residence (OR 1.4, 95% CI 1.1-1.8), advanced age (OR 1.8, 95% CI 1.3-2.5 for those aged 45-59 years, OR 2.3, 95% CI 1.6-3.4 for those aged 60-74 years, and OR 2.1, 95% CI 1.2-3.6 for those aged ≥75 years), married or remarried (OR 1.9, 95% CI 1.1-3.2), divorced or widowed (OR 2.7, 95% CI 14-5.4), moderate labor intensity (OR 1.4, 95% CI 1.1-1.8), frequent stoop (OR 1.6, 95% CI 1.1-2.4), and depressed mood (OR 1.6, 95% CI 1.2-2.1). Residents in the mountainous areas had a higher score on Oswestry Disability Questionnaire (8.3 [SD 6.3] vs 6.2 [SD 4.3]) than those in flat areas. Conclusion Mountainous areas in Chongqing had higher prevalence of low back pain as 35.6%, compared with 26.3% in flat areas, with more severe dysfunction in low back pain patients. Multifactorial analysis found that the factors associated with low back pain in Chongqing residents included mountain residence, labor intensity, stoop, psychological factors and frequency of exercise.

Abstract
Objective To compare the efficacy of acupuncture at TUNG’s extra points and traditional Chinese medicine (TCM) points for elderly patients with chronic low back pain (CLBP) in Thailand. Methods A single-blinded, randomized controlled trial with 84 elderly volunteers with CLBP was designed. The patients were randomly assigned either to the group getting acupuncture at TUNG’s extra points or to the group getting acupuncture at TCM points. The treatment period was 30 min per session for seven consecutive days. Before and after treatment, the score of the numeric rating scale (NRS), the back range of motion (BROM), and the back strength were measured and compared. Results After treatment, both groups were found with decreased NRS scores and increased BROM (P<0.05), but with no statistical difference in their back strength in comparison with that before treatment in the same group (P>0.05). Regarding the between-group comparison, no significant differences were found in the NRS score or BROM in the direction of forward flexion and right lateral flexion or the back strength after treatment (P>0.05). However, statistical differences were found in the BROM in directions of back extension (P<0.01) and left lateral flexion (P<0.05). Conclusion Acupuncture at TUNG’s extra points can decrease the low back pain NRS score and increase the back strength and the BROM in directions of forward flexion and right lateral flexion, equivalent to acupuncture at TCM points. Acupuncture at TCM points has a better effect in increasing the BROM in directions of back extension and left lateral flexion; acupuncture at TUNG’s extra points is suitable for elderly CLBP patients, and it should be supported and promoted.

Abstract
PURPOSE This study aimed to assess the prevalence of chronic low back pain (CLBP) and related biopsychosocial factors in urban and rural communities in Benin. METHODS This is a population-based observational cross-sectional survey. An interviewer-administered electronic questionnaire was used to collect information on demographic, socio-economic, behavioral, and psychological factors relating to CLBP risk factors and medical history of participants. The numeric pain rating scale and the Beck Depression Inventory were used to assess pain intensity and the level of depression, respectively. Bivariate analyses were performed to investigate the association between sociodemographic, behavioral, and psychological factors and CLBP. Sequential multiple regression analyses were subsequently performed to predict the occurrence of CLBP. RESULTS A total of 4320 participants, with a mean age ± SD of 32.9 ± 13.1 years, of which 40.7% were females and 50.1% from an urban area, were enrolled in the study. We found a global prevalence rate of CLBP of 35.5% [95% CI 34.1-36.9%]. The prevalence in urban areas was 30.68% [95% CI 28.9-32.8%]) while 40.2% was found in rural areas [95% CI 38.1-42.2%]). Age (p < 0.001), level of education (p = 0.046), marital status (p < 0.001), working status (p < 0.003), tobacco use (p < 0.016) and regular physical activity (p < 0.011) were associated with CLBP. In urban areas, only the level of education was able to predict the prevalence of CLBP (R2 = 61%). In rural areas, CLBP was predicted by age, marital and working status (R2 = 89%). CONCLUSIONS This study showed a high prevalence of CLBP among urban and rural communities in Benin. Age, level of education, marital status, and working status were significantly associated with CLBP in Benin.

Abstract
Intervertebral disc degeneration (IVDD) has been the major contributor to chronic lower back pain (LBP). Abnormal apoptosis, senescence, and pyroptosis of IVD cells, extracellular matrix (ECM) degradation, and infiltration of immune cells are the major molecular alternations during IVDD. Changes at tissue level frequently occur at advanced IVD tissue. Ectopic ingrowth of nerves within inner annulus fibrosus (AF) and nucleus pulposus (NP) tissue has been considered as the primary cause for LBP. Innervation at IVD tissue mainly included sensory and sympathetic nerves, and many markers for these two types of nerves have been detected since 1940. In fact, in osteoarthritis (OA), beyond pain transmission, the direct regulation of neuropeptides on functions of chondrocytes have attracted researchers' great attention recently. Many physical and pathological similarities between joint and IVD have shed us the light on the neurogenic mechanism involved in IVDD. Here, an overview of the advances in the nervous system within IVD tissue will be performed, with a discussion on in the role of nerve fibers and their neurotransmitters in regulating IVDD. We hope this review can attract more research interest to address neuromodulation and IVDD itself, which will enhance our understanding of the contribution of neuromodulation to the structural changes within IVD tissue and inflammatory responses and will help identify novel therapeutic targets and enable the effective treatment of IVDD disease.

Abstract
Background Illness perception is related to management patterns and pain intensity, but among elderly with low back pain, this relation is unclear. The aims of this study were to analyse the associations between illness perception, pain intensity and health related quality of life in a group of elderly with low back pain and explore how different illness perception profiles would cluster and differ in terms of pain, quality of life and choice of management. Method This was a cross-sectional survey based on a cohort of originally 640 Danish children. Of the 311 respondents in 2019, 69% reported low back pain within last year and were included. Associations between illness perceptions (Brief illness perception questionnaire), health related quality of life (EuroQol-5 Domain-3L) and low back pain intensity were assessed, and participants were clustered based on their perceptions using hierarchical and K-means cluster analysis. Cluster differences in pain, quality of life and use of pharmacological and non-pharmacological treatments were explored. Results Among the 213 individuals with low back pain, 33% reported severe or fluctuating pain intensity. Higher pain intensity was associated with perceiving low back pain as a greater threat. Participants reporting fluctuating pain perceived their low back pain almost as threatening as participants reporting severe pain. Two clusters were identified. Cluster 1 reported lower quality of life (difference in medians: -0.176 (95% CI [-0.233--0.119 ])) and was more likely to report severe or fluctuating pain (37.7% vs. 4.5% [P < 0.0001]) and to use pharmacological treatments than Cluster 2 (37.7% vs. 14.9% [P < 0.001]). No association was found between clusters concerning use of non-pharmacological treatments (P = 0.134). Conclusion Based on illness perceptions, two clusters differing in pain intensity, quality of life and use of pharmacological treatments were identified. Targeting illness perceptions may be beneficial during rehabilitation or when guiding patients with low back pain in choice of management.

Abstract
OBJECTIVES (1) To determine the prevalence of spine and upper limb osteoarthritis (OA) and pain in retired Olympians; (2) identify risk factors associated with their occurrence and (3) compare with a sample of the general population. METHODS 3357 retired Olympians (44.7 years) and 1735 general population controls (40.5 years) completed a cross-sectional survey. The survey captured demographics, general health, self-reported physician-diagnosed OA, current joint/region pain and significant injury (lasting ≥1 month). Adjusted ORs (aORs) compared retired Olympians and the general population. RESULTS Overall, 40% of retired Olympians reported experiencing current joint pain. The prevalence of lumbar spine pain was 19.3% and shoulder pain 7.4%, with lumbar spine and shoulder OA 5.7% and 2.4%, respectively. Injury was associated with increased odds (aOR, 95% CI) of OA and pain at the lumbar spine (OA=5.59, 4.01 to 7.78; pain=4.90, 3.97 to 6.05), cervical spine (OA=17.83, 1.02 to 31.14; pain=9.41, 6.32 to 14.01) and shoulder (OA=4.91, 3.03 to 7.96; pain=6.04, 4.55 to 8.03) in retired Olympians. While the odds of OA did not differ between Olympians and the general population, the odds of lumbar spine pain (1.44, 1.20 to 1.73), the odds of shoulder OA after prior shoulder injury (2.64, 1.01 to 6.90) and the odds of cervical spine OA in female Olympians (2.02, 1.06 to 3.87) were all higher for Olympians compared with controls. CONCLUSIONS One in five retired Olympians reported experiencing current lumbar spine pain. Injury was associated with lumbar spine, cervical spine and shoulder OA and pain for Olympians. Although overall OA odds did not differ, after adjustment for recognised risk factors, Olympians were more likely to have lumbar spine pain and shoulder OA after shoulder injury, than the general population.

Abstract
OBJECTIVES There is scarce information on preventive psychological and behavioural methods applicable to sub-acute (4-12 weeks) back pain, a precursor to chronic back pain. We conducted a systematic literature review of the efficacy of psychological interventions in preventing chronicity of sub-acute back pain. METHODS A systematic literature search in CINAHL, CENTRAL, MEDLINE, PubMed®, PsychINFO, Scopus and Web of Science databases. RESULTS From a total of 271 records, only three studies met the eligibility criteria. In two of the reviewed studies, the interventions had an insignificant preventive impact on the chronification of back pain. In one study the CBT intervention proved promising in preventing back pain related disability. None of the studies reported a significant impact on pain intensity at follow-up. CONCLUSIONS The psychological interventions did not impact pain outcomes. There is a disproportion between novel knowledge on psychological factors involved in the transition to chronic pain and corresponding preventive treatments. Additional studies on psychological interventions on sub-acute back pain prevention are highly warranted due to the enormous burden that back pain creates when it becomes chronic. The research project has the ethical approval of the Research Ethical Committee at Helsinki University Hospital, HUS/2435/2017.

Abstract
OBJECTIVE Modic changes (MCs) are known to be associated with low back pain (LBP). Literature contains conflicting reports about the prevalence of MCs and other spinal phenotypes among different populations with LBP patients. We aimed to evaluate the prevalence of MCs in the lumbar spine and associated features in Eastern Anatolian chronic LBP patients. METHODS The study sample comprised of 786 consecutive patients [(490 female, 296 male), (mean age 39.7; range 20-78)] with a history of low back pain for at least 3 months. Data about MCs involvement, Schmorl's nodes (SN), disc degeneration (DD), disc displacement, disc height and osteophytes were obtained via MRI. Patients' demographic characteristics, Oswestry disability index (ODI) and visual analog scale (VAS) scores were assessed using a questionnaire. RESULTS MCs were present in 67.2% (528/786) of the patients. Of all evaluated lumbar-level changes, 86 (6.2%) were Type I, 991 (76.8%) were Type II, 11 (0.8%) were Type III, 47 (6.5%) were Type II/III, 89 (8.5%) were Type I/II, and 29 (1.2%) were Type I/II/III MCs. MCs were significantly associated with severe DD (p < 0.001), disc displacement (p < 0.001), SN (p < 0.001), and osteophytes (p < 0.001). In the multivariate regression analysis, BMI (for both ODI and VAS) and age (only for ODI) were the only independent predictors of clinical severity. CONCLUSIONS The present study is the largest cross-sectional study of adult members of the Eastern Anatolian population with chronic LBP. Modic changes were detected in 67.2% of patients with chronic LBP and the prevalence of other phenotypic features differed significantly between MCs and non-MCs disc levels. Nevertheless, the results of the current study do not support a causal relationship of MCs or any MRI changes with clinical symptom severity.

Abstract
BACKGROUND Low back pain (LBP) has been associated with worse hip function for persons with femoroacetabular impingement syndrome (FAIS). Reports are limited to surgical populations and based on the presence or absence of LBP, regardless of pain severity. OBJECTIVES To report the prevalence of clinically significant LBP for persons with FAIS; compare demographics, pain, and function between those with and without clinically significant LBP; and evaluate relationships between hip function and both LBP-related disability and LBP severity. We hypothesized that participants with LBP would be older, have higher body mass index (BMI), and report worse groin pain, longer symptom duration, and worse hip function. We hypothesized that worse LBP-related disability and LBP severity would be related to worse hip function. DESIGN Observational cross-sectional study. SETTING Hip preservation clinic. PARTICIPANTS 158 persons with FAIS. INTERVENTIONS n/a MAIN OUTCOME MEASURE(S): Visual analog pain scales (VAS 0-100) were used to categorize participants with (≥30) and without (<30) clinically significant LBP. Age, sex, BMI, pain severity and duration, and hip function (33-item Hip Outcome Tool [iHOT33]) were compared between those with and without clinically significant LBP. Correlations were evaluated between the modified Oswestry Disability Index (ODI) and iHOT33, ODI and groin pain severity, LBP severity and iHOT33, and LBP and groin pain severity. RESULTS Sixty percent of participants reported clinically significant LBP (n = 95). These participants reported worse iHOT33 scores (mean difference: 10.1 points) than those without clinically significant LBP (p = .001). Worse ODI scores were associated with worse iHOT33 scores (P < .001; ρ = -0.74). Significant relationships were also observed between (1) ODI and groin pain, (2) LBP and iHOT33, and (3) LBP and groin pain, but the magnitudes of these correlations were weak (ρ ≤ 0.36). CONCLUSIONS Clinically significant LBP is highly prevalent in persons with FAIS and is associated with worse hip function. Worse LBP-related disability, but not LBP severity, was strongly associated with worse hip function.

Abstract
OBJECTIVES Low back pain (LBP) is a common chronic condition among sedentary workers that causes long-term productivity loss. This study aimed to identify the relationships of individual and occupational factors with LBP among Bangladeshi online professionals. METHODS We conducted a cross-sectional study involving 468 full-time online professionals who usually worked in a sitting position. One-month LBP complaints were assessed using a musculoskeletal subscale of subjective health complaints. The chi-square test was used to measure associations between categorical predictors and LBP, and multivariable logistic regression was conducted to identify the variables significantly associated with LBP. RESULTS LBP within the last month was reported by 65.6% of participants. Multivariable logistic regression analysis indicated that age >30 years (adjusted odds ratio [aOR], 0.40; 95% confidence interval [CI], 0.23 to 0.70) and being married (aOR, 0.59; 95% CI, 0.36 to 0.97) had significant negative associations with LBP. Significant positive associations were found for spending >50 hours weekly on average working in a sitting position (aOR, 1.61; 95% CI, 1.05 to 2.49), being overweight and obese (aOR, 1.87; 95% CI, 1.16 to 2.99), sleeping on a soft mattress (aOR, 2.01; 95% CI, 1.06 to 3.80), and ex-smoking status (aOR, 3.33; 95% CI, 1.41 to 7.87). CONCLUSIONS A high prevalence of LBP was found among full-time online professionals. Long working hours in a sitting position showed a significant association with developing LBP. Smoking history, body mass index, and sleeping arrangements should also be considered while considering solutions for LBP prevalence among online professionals.

Abstract
Aim: The high heterogeneity in the definitions of low back pain encountered in the literature has led to the development of standardized definitions of this condition called “Delphi definitions of low back pain prevalence (Delphi DOLBaPP)” by a group of international researchers. In order to be widely used, these definitions need to be adapted according to the cultural and linguistic context. The aim of this work was to perform the cross-cultural adaptation of the Delphi DOLBaPP definitions in Quebecc French and to pre-test them among French-speaking adults.
Methods: In order to enable practical use of the Delphi DOLBaPP definitions in different contexts, their presentation was adapted in the form of a questionnaire (referred to as the “Delphi DOLBaPP questionnaire”). The process of cross-cultural adaptation of the Delphi DOLBaPP questionnaire in French was conducted according to the most recognized recommendations for the cultural adaptation of measuring instruments. The resulting questionnaire and an evaluation form were then submitted to a sample of 82 adults.
Results: A total of 41 participants (50.0%) reported low back pain. A high proportion of participants (89.0%) stated that it took them less than 5 minutes to complete the questionnaire. More than 62.0% of them did not find any question poorly worded or confusing. Nearly 80.0% of the participants found the questionnaire easy to understand. The cross-cultural adaptation process suggested minor modifications to the original Delphi DOLBaPP questionnaire.
Conclusions: This study has produced a cross-cultural adaptation of the Delphi DOLBaPP questionnaire in Quebec French that will enable French-speaking populations to share the benefits of using standardized definitions of low back pain in epidemiological studies.

Prevalence of Self-Reported Work-Related Lower Back Pain and Its Associated Factors in Ethiopia: A Systematic Review and Meta-Analysis. JOURNAL OF ENVIRONMENTAL AND PUBLIC HEALTH 2021; 2021:6633271. [PMID: 34603457 PMCID: PMC8486508 DOI: 10.1155/2021/6633271] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/02/2021] [Revised: 08/02/2021] [Accepted: 08/24/2021] [Indexed: 11/21/2022]
Abstract
Introduction Low back pain is the commonest musculoskeletal disorder affecting every socioeconomic group of the world's population. The lifetime risk of developing low back pain is about 60%–80%. The pooled prevalence and associated factors of low back pain have not yet been determined in Ethiopia. Thus, this study was aimed at assessing the overall prevalence of low back pain and its associated factors in Ethiopia. Methods A systematic search of PubMed, Scopus, Science Direct, and Google Scholar for observational studies reporting data on the prevalence and associated factors of low back pain was conducted. Relevant data were extracted with a standardized data extraction excel form. Stata 14 was employed for the meta-analysis. Heterogeneity was assessed by Cochran's Q test and I2 values of a forest plot. Publication bias was checked using a funnel plot and Egger's test. A random-effects model was used in the analysis. Result A total of thirty-two studies were included for the systematic review. Twenty-four and sixteen studies were used to pool the overall low back pain prevalence and associated factors, respectively. The overall pooled annual prevalence of low back pain in Ethiopia was estimated to be 54.05% (95% CI: 48.14–59.96). Age, sex, body mass index, work experience, working hours, lack of safety training, awkward working posture, work shift, prolonged standing, lifting heavy objects, sleeping disturbance, history of back trauma, previous medical history of musculoskeletal disorder, and lack of adequate rest interval at work were significantly associated with low back pain. Conclusion The current systematic review and meta-analysis revealed a higher prevalence of lower back pain in Ethiopia. Most of the low back pain epidemiological studies conducted in Ethiopia focused on specific occupational settings, making pooling of data and comparison with other countries challenging. Thus, further general population studies are recommended.

Abstract
Sarcopenia is characterized by a decline in systemic muscle mass and physical performance. Disc degeneration also causes back muscle atrophy. Therefore, we aimed to evaluate the influence of systemic muscle mass decline on back muscle atrophy and fatty infiltration compared to disc degeneration. We included 127 patients (65.54 ± 14.93 years) with back pain who underwent lumbar spine magnetic resonance imaging (MRI). Axial T2-weighted MRI data of the L4-5 and L5-S1 levels were used to measure the cross-sectional area (CSA) of the psoas and spinal muscles. The psoas index (cm2/m2) was used as a surrogate for systemic muscle mass. The Pfirrmann grading system was used to evaluate intervertebral disc degeneration. The functional area of the back muscles was calculated by subtracting the fat infiltration area from the CSA; the functional CSA ratio was calculated by dividing the functional CSA by the CSA. Image-processing software (ImageJ; National Institutes of Health, Bethesda, MD, USA) was used for analysis. Psoas index and aging significantly affected CSA and the ratio of functional CSA of the back muscles and multifidi. Disc degeneration did not significantly affect the back muscles beyond aging in patients with back pain. Males showed substantially higher CSA of the back muscles and multifidi than females; however, sex did not affect the functional CSA ratio of these muscles. Systemic muscle mass decline showed a more powerful influence on back muscle atrophy and fatty infiltration than disc degeneration. Therefore, proper evaluation of sarcopenia is needed for patients with chronic back pain and back muscle degeneration.

Abstract
BACKGROUND In contrast to the broad evidence for the effectiveness of multidisciplinary biopsychosocial rehabilitation (MBR) in chronic low back pain (CLBP) patients of working age, little is known about the benefit in patients aged ≥ 65 years. AIM To quantify the short-term and 12-month effects of a 3-week CLBP specific MBR program in patients ≥ 65 years of age; to compare the effects in patients ≥ 65 years of age to the effects in younger patients. DESIGN Observational prospective cohort study. SETTING Outpatient clinic at a tertiary physical medicine and rehabilitation centre. POPULATION Consecutive patients with CLBP who participated in a CLBP a specific MBR program. METHODS The 3-week MBR program included 44 hours of treatment. The primary outcomes pain and disability were measured by the North American Spine Society Questionnaire (NASS). Secondary outcome measures were the Short-Form 36 (SF-36) and the numerical rating scale for pain. Effects were quantified using effect sizes (ES). RESULTS From 203 included patients, 104 patients older than 65 years (mean: 70.7; SD: 4.0) were compared to 99 patients younger than 65 years (mean: 56.4; SD: 6.7). The older patients had more comorbidities (two or more comorbidities: 49.5% versus 23.5%; p < 0.001). Both groups showed significant improvements in pain and disability at discharge (both groups: p<0.001) and at the 12 months' follow-up (old: p < 0.001; young: 0.039) with slightly higher effects for the older patients compared to the younger patients (discharge: ES = 0.67 versus ES = 0.53; 12 months: ES = 0.42 versus ES = 0.29). Both groups also improved in the SF-36 Physical Component Summary with slightly lower effects for the older patients (discharge: ES =0.31, p<0.001 versus ES=0.43, p<0.001; 12 months: ES=0.27, p=0.025 versus ES=0.39, p=0.001). The group differences of the change scores were not significant in any of the outcome measures. CONCLUSIONS MBR shows similar improvements in pain and disability in patients aged ≥ 65 compared to younger patients for at least 12 months. CLINICAL REHABILITATION IMPACT The findings support the concept of MBR in the growing population of CLBP patients older than 65 years of age.

Abstract
ABSTRACT Back pain is a leading cause of disability worldwide and is common in older adults. No clinical prediction models for poor long-term outcomes have been developed in older patients with back pain. This study aimed to develop and internally validate 3 clinical prediction models for nonrecovery in this population. A prospective cohort study in general practice was conducted (Back Complaints in the Elders, Netherlands), including 675 patients >55 years with a new episode of care for back pain. Three definitions of nonrecovery were used combining 6-month and 12-month follow-up data: (1) persistent back pain, (2) persistent disability, and (3) perceived nonrecovery. Sample size calculation resulted in a maximum of 14 candidate predictors that were selected from back pain prognostic literature and clinical experience. Multivariable logistic regression was used to develop the models (backward selection procedure). Models' performance was evaluated with explained variance (Nagelkerke's R2), calibration (Hosmer-Lemeshow test), and discrimination (area under the curve [AUC]) measures. The models were internally validated in 250 bootstrapped samples to correct for overoptimism. All 3 models displayed good overall performance during development and internal validation (ie, R2 > 30%; AUC > 0.77). The model predicting persistent disability performed best, showing good calibration, discrimination (AUC 0.86, 95% confidence interval 0.83-0.89; optimism-adjusted AUC 0.85), and explained variance (R2 49%, optimism-adjusted R2 46%). Common predictors in all models were: age, chronic duration, disability, a recent back pain episode, and patients' recovery expectations. Spinal morning stiffness and pain during spinal rotation were included in 2 of 3 models. These models should be externally validated before being used in a clinical primary care setting.

Abstract
Low back pain is a major cause of disability in older adults, and results in many emergency department visits each year. Characteristics of the older back pain population are largely unknown. We conducted a retrospective study to examine the prevalence and patient characteristics for older (≥ 65 years of age) and younger (16-64 years of age) adults presenting with back pain. Study objectives were to describe the characteristics of older adults with back pain presenting to an emergency department and to identify age-group based differences in management. Older adults were most commonly diagnosed with non-specific low back pain (49%). For older adults with this diagnosis, the length of stay was 2.1 times longer (p < 0.001), and odds of being admitted to the hospital were 5.1 times higher (p < 0.001) than for younger adults. Patterns of management are different for younger and older adults with low back pain; this information can be used to direct future resource planning.

Complex sociodemographic inequalities in consultations for low back pain: lessons from multilevel intersectional analysis. Pain 2021; 162:1135-1143.

Abstract
Supplemental Digital Content is Available in the Text. We found substantial individual heterogeneity in consultation for low back pain that could not be explained by combination of age, sex, education, income, and nativity. Sociodemographic inequalities in the occurrence of low back pain (LBP) are well-studied. This study aimed to examine complex sociodemographic inequalities in the risk of LBP consultation in the population from a socioeconomical intersectional perspective. Using register data, we identified 458,852 individuals aged 35 to 75 years residing in Skåne in 2013, with no previous LBP consultation since 2006. We created 108 strata using categories of age, sex, education, income, and nativity. With individuals nested within strata, we modelled the absolute risk of LBP consultation during 2014 in a series of multilevel logistic regression models. We quantified discriminatory accuracy (DA) of these variables by computing the variance partition coefficient and area under the receiver operating characteristic curve (AUC). We identified 13,657 (3.0%) people with an LBP consultation. The absolute risk ranged from 2.1% (95% credible interval: 1.9%-2.3%) among young native men with high education and high income to 4.8% (4.3%-5.5%) among young foreign-born women with medium education and low income (2.3-fold relative difference). Discriminatory accuracy of intersectional strata was very low (variance partition coefficient 1.1% (0.7-1.6); and AUC 0.56 [0.55-0.56]). Sex (35.6%) and nativity (19.2%) had the largest contributions in explaining the initially small between-strata variation in risk of LBP. The low DA of the intersectional strata indicates the existence of limited intersectional inequalities in LBP consultation. Therefore, interventions to reduce LBP risk should be universal rather than targeted to specific socioeconomic groups with a higher average risk. Before planning targeted intervention, other risk factors with higher DA need to be identified.

Abstract
To investigate the prevalence of low back pain (LBP) and associated factors in the older adult Amazonia Brazilian community, a cross-sectional study was conducted to evaluate 700 participants that were ≥60 years old. Pain intensity and functional disability were assessed using the Numerical Pain Scale and the Roland Morris Questionnaire, respectively, and their sociodemographic, clinical, and behavior variables were collected, i.e., age, sex, education level, socioeconomic level, anthropometric measurements, physical activity, health perception, and emotional state. The punctual prevalence rates of LBP were 42.4% (95% CI: 38.2-46.6%), and for the last 365 days, these prevalence rates were 93.7% (95% CI: 91.3-95.6%), the mean pain and functional disability scores were 6.17 ± 2.13 and 11.30 ± 6.07, and the moderate-to-severe disability was 39.7%. Pain and functional disability were associated with sex, chronic diseases, body mass index (BMI), physical activity level, health perception, and emotional level. In conclusion, the prevalence of LBP was high (for both punctual and the last 365 days), but the variables associated with being female, fewer years of schooling, sedentary behavior, diseases related to diet and the cardiovascular system, and impaired emotional levels had a higher level LBP, even though they considered themselves in good health. These findings can aid with coordinated efforts from government and health professionals to help manage and promote the prevention of LBP by considering the older adult population's needs in the state of Amazonas.

[PMID: 33892643 PMCID: PMC8066480 DOI: 10.1186/s12877-021-02218-6] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2020] [Accepted: 04/15/2021] [Indexed: 12/28/2022] Open
Abstract
BACKGROUND Musculoskeletal conditions are the primary reason older adults seek general medical care, resulting in older adults as the highest consumers of health care services. While there is high use of chiropractic care by older adults, there is no recent, specific data on why older adults seek chiropractic care and how chiropractors manage conditions. Therefore, the purpose of this study was to describe the demographic characteristics of older adults seeking chiropractic care, and to report problems diagnosed by chiropractors and the treatment provided to older adults who seek chiropractic care. METHODS A secondary data analysis from two, large cross-sectional observational studies conducted in Australia (COAST) and Canada (O-COAST). Patient encounter and diagnoses were classified using the International Classification of Primary Care, 2nd edition (ICPC-2), using the Australian ICPC-2 PLUS general practice terminology and the ICPC-2 PLUS Chiro terminology. Descriptive statistics were used to summarize chiropractor, patient and encounter characteristics. Encounter and patient characteristics were compared between younger (< 65 years old) and older (≥65 years old) adults using χ2 tests or t-tests, accounting for the clustering of patients and encounters within chiropractors. RESULTS A total of 6781 chiropractor-adult patient encounters were recorded. Of these, 1067 encounters were for persons aged > 65 years (16%), from 897 unique older patients. The most common diagnosis within older adult encounters was a back problem (56%), followed by neck problems (10%). Soft tissue techniques were most frequently used for older patients (85 in every 100 encounters) and in 29 of every 100 encounters, chiropractors recommended exercise to older patients as a part of their treatment. CONCLUSIONS From 6781 chiropractor-adult patient encounters across two countries, one in seven adult chiropractic patients were > 65 years. Of these, nearly 60% presented with a back problem, with neck pain and lower limb problems the next most common presentation to chiropractors. Musculoskeletal conditions have a significant burden in terms of disability in older adults and are the most commonly treated conditions in chiropractic practice. Future research should explore the clinical course of back pain in older patients seeking chiropractic care and compare the provision of care to older adults across healthcare professions.
