Evidence for managing chronic low back pain in primary care: a review of recommendations from high-quality clinical practice guidelines

Effects of MLS Laser on pain, function, and disability in chronic non-specific low back pain: A double-blind placebo randomized-controlled trial

BACKGROUND

Among non-pharmacological interventions, Multiwave Locked System (MLS) Laser therapy has been used in patients with several musculoskeletal pathologies and in combination with other therapeutical interventions. The effects of sole MLS therapy on pain and function in patients with chronic non-specific low-back pain are unknown.

OBJECTIVE

The objective of this study was to investigate the effects of MLS Laser therapy on pain, function, and disability in patients with chronic non-specific low back pain in comparison to a placebo treatment group.

METHODS

Forty-five patients were randomized into two groups: the MLS Laser group and the Sham Laser group, undergoing 8 sessions of either a MLS Laser therapy or a Sham Laser therapy, respectively. At the beginning of the therapy (T0), at the end of the therapy (T1), and 1 month after the end of therapy (T2) patients were assessed for low back pain (by means of a VAS scale), function (by means of kinematic and electromyographic assessment of a forward bending movement) and self-reported disability (by means of the Roland-Morris and Oswestry Disability questionnaires).

RESULTS

There was a significant reduction of pain and disability in both groups at T1 and T2 in comparison with T0. At T2 patients in the MLS group showed a significantly lower pain in comparison with patients in the Sham group (VAS = 2.2 ± 2 vs. 3.6 ± 2.4; p< 0.05). No differences between the two groups were found for function and disability.

CONCLUSION

Both MLS Laser and Sham Laser therapies lead to a significant and comparable reduction in pain and disability in patients with chronic non-specific low back pain. However, one month after treatment, MLS Laser therapy has been found to be significantly more effective in reducing pain as compared to sham treatment.

"Finding a new normal: the lived experience of persons' journey towards coping with persistent low back pain"

INTRODUCTION

Persistent low back pain (PLBP) is the biggest global cause of disability. Persons with PLBP experience biographic disruption and existential crisis. Guidelines recommend a biopsychosocial approach to management, with the emphasis on coping strategies.

PURPOSE

However, there is a paucity of research exploring the lived experience of persons who self-identify as coping with PLBP.

METHOD

The study used an interpretive phenomenological approach, analyzing transcripts from 1:1 interviews with six persons who self-identify as coping with PLBP. Poetic language was used to elicit empathic, embodied relational understanding and convey a richer understanding of the phenomenon that authentic quotations might not able to reveal.

FINDINGS AND CONCLUSION

Participants' descriptions conveyed the sense of a journey, starting with the loss of a sense of self as they engaged in the pain battle, followed by a transition toward a new 'normal,' in which time, acceptance and trust in their own intuition were meaningful components. Although anxiety and fear were a continued presence, but they became more manageable. Society's role in the coping process was significantly meaningful and is something which requires reflections from therapists' and more widely.

Recent clinical practice guidelines for the management of low back pain: a global comparison

BACKGROUND

Low back pain (LBP) is a significant health problem worldwide, with a lifetime prevalence of 84% in the general adult population. To rationalise the management of LBP, clinical practice guidelines (CPGs) have been issued in various countries around the world. This study aims to identify and compare the recommendations of recent CPGs for the management of LBP across the world.

METHODS

MEDLINE, EMBASE, CINAHL, PEDro, and major guideline databases were searched from 2017 to 2022 to identify CPGs. CPGs focusing on information regarding the management and/or treatment of non-specific LBP were considered eligible. The quality of included guidelines was evaluated using the Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument.

RESULTS

Our analysis identified a total of 22 CPGs that met the inclusion criteria, and were of middle and high methodological quality as assessed by the AGREE II tool. The guidelines exhibited heterogeneity in their recommendations, particularly in the approach to different stages of LBP. For acute LBP, the guidelines recommended the use of non-steroidal anti-inflammatory drugs (NSAIDs), therapeutic exercise, staying active, and spinal manipulation. For subacute LBP, the guidelines recommended the use of NSAIDs, therapeutic exercise, staying active, and spinal manipulation. For chronic LBP, the guidelines recommended therapeutic exercise, the use of NSAIDs, spinal manipulation, and acupuncture.

CONCLUSIONS

Current CPGs provide recommendations for almost all major aspects of the management of LBP, but there is marked heterogeneity between them. Some recommendations lack clarity and overlap with other treatments within the guidelines.

Developing a low back pain guideline implementation programme in collaboration with physiotherapists and chiropractors using the Behaviour Change Wheel: a theory-driven design study

BACKGROUND

Low back pain is still the leading cause of disability and societal burden, with 619 million prevalent cases worldwide in 2020. Most countries produce clinical guidelines to support healthcare professionals in evidence-based care regarding low back pain. However, several studies have identified relatively poor uptake of guidelines. Tailored strategies to facilitate the implementation of guidelines have been argued to increase uptake. This study aimed to develop a contextually tailored implementation programme to enhance evidence-based low back pain care among Danish physiotherapists and chiropractors in primary care.

METHODS

A theory-driven implementation programme development study was conducted using the Behaviour Change Wheel, with high healthcare professional involvement. Data collection included four workshops with seven physiotherapists and six chiropractors from primary care clinics. The development process consisted of [1] establishing a theoretical frame, [2] involving participants, [3] understanding the behaviour, [4] designing the implementation programme, and [5] final implementation programme.

RESULTS

The target behaviours selected (guideline recommendations) for the implementation programme were (i) screening of psychosocial risk factors and (ii) offering patient education. The barriers and facilitators for the selected behaviours were described and linked to intervention functions and behavioural techniques. Finally, the implementation programme comprised five strategies: webinars, e-learning videos, communication exercises, peer learning, and group dialogue meetings. In addition, the programme consisted of implementation support: champions, a physical material folder, a weekly email reminder, a specially designed website and a visit from an implementation consultant. An essential element of the overall programme was that it was designed as a step-by-step implementation process consisting of 16 h of education and training distributed over 16 weeks.

CONCLUSIONS

A programme for implementing low back pain guideline recommendations was developed based on behaviour change theory and four co-design workshops involving healthcare professionals to overcome the contextually identified barriers. A theory-driven approach involving healthcare professionals was useful in identifying relevant target behaviours and tailoring the programme to consider contextual barriers and facilitators for implementation. The effectiveness of the final implementation programme will be evaluated in the project's next phase.

Association of Opioid Use Disorder Diagnosis With Use of Physical Therapy and Chiropractic Care Among Chronic Low Back Pain Patients: A Group-Based Trajectory Analysis

Nonpharmacologic approaches are recommended as first-line treatment for chronic pain, and their importance is heightened among individuals with co-occurring opioid use disorder (OUD), in whom opioid therapies may be particularly detrimental. Our objectives were to assess the receipt and trajectories of nonpharmacologic pain treatment and determine the association of OUD diagnosis with these trajectories. This retrospective cohort study used Medicare claims data from 2016 to 2018 and applied group-based trajectory models to identify distinct patterns of physical therapy (PT) or chiropractic care treatment over the 12 months following a new episode of chronic low back pain. We used logistic regression models to estimate the association of co-occurring OUD with group membership in PT and chiropractic trajectories. Our sample comprised 607,729 beneficiaries at least 18 years of age, of whom 11.4% had a diagnosis of OUD. The 12-month prevalence of PT and chiropractic treatment receipt was 24.7% and 27.1%, respectively, and lower among Medicare beneficiaries with co-occurring OUD (PT: 14.6%; chiropractic: 6.8%). The final models identified 3 distinct trajectories each for PT (no/little use [76.6% of sample], delayed and increasing use [8.2%], and early and declining use [15.2%]); and chiropractic (no/little use [75.0% of sample], early and declining use [17.3%], and early and sustained use [7.7%]). People with OUD were more likely to belong in trajectories with little/no PT or chiropractic care as compared to other trajectories. The findings indicate that people with co-occurring chronic pain and OUD often do not receive early or any nonpharmacologic pain therapies as recommended by practice guidelines. PERSPECTIVE: PT and chiropractic care use were low overall and even lower among Medicare beneficiaries with co-occurring OUD compared with those without OUD. As updated guidelines on pain management are promulgated, targeted interventions (eg, insurance policy, provider, and patient education) are needed to ensure equitable access to guideline-recommended pain therapies.

Trials Investigating Exercise for Low Back Pain Lack Pragmatic Application: A Systematic Review

OBJECTIVE

To systematically review the orientation of trials analyzing exercise for low back pain (LBP) on the efficacy-effectiveness spectrum.

DATA SOURCES

PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Ovid MEDLINE were searched for trials published between January 1, 2010, and August 13, 2022.

STUDY SELECTION

Randomized controlled trials investigating exercise for adults with LBP.

DATA EXTRACTION

Two reviewers independently used the Rating of Included Trials on the Efficacy-Effectiveness Spectrum (RITES) tool to determine the efficacy-effectiveness orientation. The same 2 reviewers assessed the risk of bias for all studies using the Cochrane Collaboration risk of bias 2.0 tool.

DATA SYNTHESIS

The search identified 2975 records. Full-text review was conducted on 674 studies, and 159 studies were included. The proportion of trials with a strong or rather strong efficacy orientation (RITES rating=1 or 2), balanced emphasis (RITES rating=3), or strong or rather strong effectiveness (RITES rating=4 or 5) orientation on the efficacy-effectiveness spectrum within each RITES domain were reported. A greater proportion of trials had an efficacy orientation when compared with effectiveness or a balanced emphasis within 4 domains: participant characteristics: efficacy 43.9%, 41.9% effectiveness, balanced 14.5%; trial setting: 69.0% efficacy, effectiveness 15.8% balanced 15.2%; flexibility of interventions: 74.2% efficacy, effectiveness 8.8%, balanced 17.0%; clinical relevance of experimental and comparison interventions: 50.3% efficacy, 33.3% effectiveness 33.3%, balanced 16.4%. A high risk of bias was found in 42.1% (n=67) of trials.

CONCLUSION

Trials investigating the effect of exercise for LBP have a greater orientation toward efficacy across multiple trial design domains. Researchers should consider pragmatic designs in future trials to improve generalizability. Clinicians should consider the efficacy-effectiveness orientation when translating evidence into clinical practice.

The Impact of Hot Spring Hydrotherapy on Pain Perception and Dysfunction Severity in Patients with Chronic Low Back Pain: A Systematic Review and Meta-Analysis

Background

Chronic Low Back Pain (CLBP) is a prevalent global health issue, leading to prolonged discomfort and functional limitations. Hot spring hydrotherapy, which utilizes mineral-rich, warm spring water, offers a unique physical therapy that holds promise in alleviating CLBP symptoms.

Objective

This meta-analysis aims to assess the effectiveness of hot spring hydrotherapy in improving CLBP symptoms, encompassing pain intensity, functional disability, quality of life, and medication usage.

Methods

A systematic review and meta-analysis were conducted by searching relevant literature in multiple databases. Included studies compared hot spring hydrotherapy with control interventions or other treatments. Standardized mean differences (SMD) with 95% confidence intervals (CI) were calculated for pain intensity, functional disability, medication usage, and quality of life.

Results

A total of 16 studies met the inclusion criteria, involving 1656 participants with chronic low back pain across various countries. The meta-analysis demonstrated that hot spring hydrotherapy was effective in reducing pain intensity (SMD = -0.901, 95% CI [-1.777, -0.025], P < 0.05) and improving functional disability (SMD = -3.236, 95% CI [-4.898, -1.575], P < 0.0001) in CLBP patients. Hot spring hydrotherapy also resulted in a significant reduction in medication usage (P < 0.05). Subgroup analysis showed that the effects of hot spring hydrotherapy were more pronounced in patients aged 60 and above, while no significant differences were observed in patients below 60 years of age, single hot Spring Hydrotherapy help improve patients' quality of life.

Conclusion

Hot spring hydrotherapy is an effective intervention for improving CLBP symptoms, including pain intensity, functional disability, and medication usage. It is particularly beneficial for CLBP patients aged 60 and above. These findings support the integration of hot spring hydrotherapy into the treatment approach for CLBP, although further research is needed to determine its efficacy in younger patients and to explore the underlying mechanisms of its therapeutic effects.

Attitudes and beliefs of Brazilian physical therapists about chronic nonspecific low back pain and its impact on clinical decision-making: An Online Survey Study

INTRODUCTION

Recent clinical practice guidelines recognize the importance of the biopsychosocial model in the management of patients with chronic nonspecific low back pain, and the attitudes and beliefs of physical therapists are believed to directly influence clinical decision-making.

OBJECTIVE

To investigate factors associated to biomedical and biopsychosocial approaches and its impact on attitudes and beliefs to treat patients with chronic nonspecific low back pain.

METHOD

This was a cross-sectional study conducted online with 302 Brazilian physiotherapists who treat patients with nonspecific chronic low back pain. The HC-PAIRS and PABS-PT were used to investigate attitudes and beliefs low back pain. Descriptive statistics and bivariate analyses were performed for association tests, comparing the scores on the scales between groups. In addition, multiple linear regression analyses were also used.

RESULTS

The overall mean score of HC-PAIRS was 54.0 (9.0), and the biomedical and biopsychosocial factors of PABS-PT were 29.7 (9.0) and 36.2 (5.3), respectively. Significant associations were identified between gender (p = 0.04) and level of academic training (p < 0.00) and both scales, HC-PAIRS and PABSPT, respectively.

CONCLUSION

Sociodemographic characteristics were associated with the beliefs of physical therapists; a higher score for treatment options for chronic low back pain based on the biomedical mode, was observed in female physiotherapist and in physios with higher education level. Variables such as age and length of professional experience indicated that the lower the age and/or length of professional experience of Brazilian physical therapists, the stronger the belief in the relationship between low back pain and tissue damage.

Comparison of cognitive functional therapy and movement system impairment treatment in chronic low back pain patients: a randomized controlled trial

BACKGROUND

This study aimed to compare the effects of cognitive functional therapy (CFT) and movement system impairment (MSI)-based treatment on pain intensity, disability, Kinesiophobia, and gait kinetics in patients with chronic non-specific low back pain (CNSLBP).

METHODS

In a single-blind randomized clinical trial, we randomly assigned 91 patients with CNSLBP into CFT (n = 45) and MSI-based treatment (n = 46) groups. An 8-week training intervention was given to both groups. The researchers measured the primary outcome, which was pain intensity (Numeric rating scale), and the secondary outcomes, including disability (Oswestry disability index), Kinesiophobia (Tampa Kinesiophobia Scale), and vertical ground reaction force (VGRF) parameters at self-selected and faster speed (Force distributor treadmill). We evaluated patients at baseline, at the end of the 8-week intervention (post-treatment), and six months after the first treatment. We used mixed-model ANOVA to evaluate the effects of the interaction between time (baseline vs. post-treatment vs. six-month follow-up) and group (CFT vs. MSI-based treatment) on each measure.

RESULTS

CFT showed superiority over MSI-based treatment in reducing pain intensity (P < 0.001, Effect size (ES) = 2.41), ODI (P < 0.001, ES = 2.15), and Kinesiophobia (P < 0.001, ES = 2.47) at eight weeks. The CFT also produced greater improvement in VGRF parameters, at both self-selected (FPF[P < 0.001, ES = 3], SPF[P < 0.001, ES = 0.5], MSF[P < 0.001, ES = 0.67], WAR[P < 0.001, ES = 1.53], POR[P < 0.001, ES = 0.8]), and faster speed, FPF(P < 0.001, ES = 1.33, MSF(P < 0.001, ES = 0.57), WAR(P < 0.001, ES = 0.67), POR(P < 0.001, ES = 2.91)] than the MSI, except SPF(P < 0.001, ES = 0.0) at eight weeks.

CONCLUSION

This study suggests that the CFT is associated with better results in clinical and cognitive characteristics than the MSI-based treatment for CNSLBP, and the researchers maintained the treatment effects at six-month follow-up. Also, This study achieved better improvements in gait kinetics in CFT. CTF seems to be an appropriate and applicable treatment in clinical setting.

Process evaluation of the implementation of an evidence-based model of care for low back pain in Australian emergency departments

BACKGROUND

The Sydney Health Partners Emergency Department (SHaPED) trial targeted ED clinicians and evaluated a multifaceted strategy to implement a new model of care. The objective of this study was to investigate attitudes and experiences of ED clinicians as well as barriers and facilitators for implementation of the model of care.

DESIGN

A qualitative study.

METHODS

The EDs of three urban and one rural hospital in New South Wales, Australia participated in the trial between August and November 2018. A sample of clinicians was invited to participate in qualitative interviews via telephone and face-to-face. The data collected from the interviews were coded and grouped in themes using thematic analysis methods.

RESULTS

Non-opioid pain management strategies (i.e., patient education, simple analgesics, and heat wraps) were perceived to be the most helpful strategy for reducing opioid use by ED clinicians. However, time constraints and rotation of junior medical staff were seen as the main barriers for uptake of the model of care. Fear of missing a serious pathology and the clinicians' conviction of a need to provide something for the patient were seen as barriers to reducing lumbar imaging referrals. Other barriers to guideline endorsed care included patient's expectations and characteristics (e.g., older age and symptoms severity).

CONCLUSIONS

Improving knowledge of non-opioid pain management strategies was seen as a helpful strategy for reducing opioid use. However, clinicians also raised barriers related to the ED environment, clinicians' behaviour, and cultural aspects, which should be addressed in future implementation efforts.

Recognition of Prodromal Hypoglossal Nerve Palsy Presenting with Neck Pain as Primary Complaint: Findings from a Rare Case Report in Direct Access Physiotherapy during the COVID-19 Pandemic

Neck pain (NP) is the second most common musculoskeletal disorder. Spinal cysts (SCs) are cystic dilatations of the synovial sheaths in joints and tendons. SCs are extremely rare in the cervical spine. Typically, patients are unaware of having an SC due to its asymptomatic nature; however, when cervical SC extends, its volume could compress the surrounding structures, such as the hypoglossal nerve. Isolated hypoglossal nerve palsy (HNP) is very rare and typically presents with unilateral atrophy of the musculature of the tongue and contralateral tongue deviation. Often, patients with HNP also report occipital/neck pain. A 75-year-old man with occipital/neck pain as a primary complaint. Although difficult to observe because of the filtering facepiece two mask, difficulties in articulation and sialorrhea during the interview were noticed. These latter were cues to consider CN examination that revealed CN XII palsy. This prompted a referral for further examination that revealed an SC compressing the right hypoglossal canal. The patient was not considered a surgical candidate and was managed conservatively. This case report outlines the relevant findings relating to the triage of a rare isolated hypoglossal nerve palsy from the physiotherapist's perspective within a complex setting because of the COVID-19 pandemic. Although referred with a diagnosis of cervical radiculopathy, our case highlights that skilled physiotherapists may play a fundamental role in both the recognition and, when applicable, subsequent novel management of a non-musculoskeletal presentation.

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.

Chronic Low Back Pain: A Narrative Review of Recent International Guidelines for Diagnosis and Conservative Treatment

Chronic low back pain (cLBP) is a public and occupational health problem that is a major professional, economic and social burden. We aimed to provide a critical overview of current international recommendations regarding the management of non-specific cLBP. We conducted a narrative review of international guidelines for the diagnosis and conservative treatment of people with non-specific cLBP. Our literature search yielded five reviews of guidelines published between 2018 and 2021. In these five reviews, we identified eight international guidelines that fulfilled our selection criteria. We added the 2021 French guidelines into our analysis. Regarding diagnosis, most international guidelines recommend searching for so-called yellow, blue and black flags, in order to stratify the risk of chronicity and/or persistent disability. The relevance of clinical examination and imaging are under debate. Regarding management, most international guidelines recommend non-pharmacological treatments, including exercise therapy, physical activity, physiotherapy and education; however, multidisciplinary rehabilitation, in selected cases, is the core treatment recommended for people with non-specific cLBP. Oral, topical or injected pharmacological treatments are under debate, and may be offered to selected and well-phenotyped patients. The diagnosis of people with cLBP may lack precision. All guidelines recommend multimodal management. In clinical practice, the management of individuals with non-specific cLBP should combine non-pharmacological and pharmacological treatments. Future research should focus on improving tailorization.

Safety and efficacy of 650 nm invasive laser acupuncture on non-specific chronic low back pain: A protocol for a multicenter randomized placebo-controlled trial

Background

We aim to obtain clinical trial data regarding the safety, efficacy, and usefulness of invasive laser acupuncture (ILA) for non-specific chronic low back pain (NSCLBP) through a randomized placebo-controlled trial.

Methods

Our clinical trial will be an assessor- and patient-blinded, prospective, parallel-arm, multi-center, randomized placebo-controlled clinical trial. One hundred and six participants with NSCLBP will be allocated evenly to the 650 ILA or control group. All participants will receive education on exercise and self-management. The 650 ILA group will undergo 650 nm ILA for 10 min, and the control group will undergo sham ILA for 10 min per visit, twice a week for 4 weeks, at bilateral GB30, BL23, BL24, and BL25. The primary outcome will be the proportion of responders (≥30% reduction in pain visual analogue scale [VAS] without increased use of painkillers) at 3 days after the intervention ends. The secondary outcomes will include changes in the scores of the VAS, European Quality of Life Five Dimension Five Level scale, and Korean version of the Oswestry Disability Index at 3 days after the intervention ends and 8 weeks after the intervention ends.

Discussions

The results of our study will provide clinical evidence concerning the safety and efficacy of 650 nm ILA for the management of NSCLBP.

Implementing a new physiotherapist-led primary care model for low back pain: a qualitative study of patient and primary care team perspectives

Background

Low back pain (LBP) is one of the most common reasons for primary care visits and is the leading contributor to years lived with disability worldwide. The purpose of this study was to understand the perspectives of patients and primary care team members related to their experiences with a new physiotherapist-led primary care model for LBP.

Methods

We conducted an interpretive description qualitative study. Data were collected using a combination of semi-structured interviews and focus group discussions and analyzed using thematic analysis. Participants included adults (> 18 years of age) with LBP and primary care team members who participated in a physiotherapist-led primary care model for LBP in Kingston, Ontario, Canada.

Results

We conducted 18 semi-structured interviews with patients with LBP (10 women; median age of 52) as well as three focus group discussions with a total of 20 primary care team members representing three teams. Four themes (each with sub-themes) were constructed: 1) enhanced primary care delivery for LBP (improved access and engagement in physiotherapy care, improved communication and care integration between the physiotherapist and primary care team, less inappropriate use of healthcare resources); 2) positive patient experiences and perceived outcomes with the new model of care (physiotherapist built therapeutic alliance, physiotherapist provided comprehensive care, improved confidence in managing LBP, decreased impact of pain on daily life); 3) positive primary care team experiences with the new model of care (physiotherapist fit well within the primary care team, physiotherapist provided expertise on LBP for the primary care team, satisfaction in being able to offer a needed service for patients); and 4) challenges implementing the new model of care (challenges with prompt access to physiotherapy care, challenges making the physiotherapist the first contact for LBP, and opportunities to optimize communication between the physiotherapist and primary care team).

Conclusions

A new physiotherapist-led primary care model for LBP was described by patients and primary care team members as contributing to positive experiences and perceived outcomes for patients, primary care team members, and potentially the health system more broadly. Results suggest that this model of care may be a viable approach to support integrated and guideline adherent management of LBP in primary care settings.

Best Exercise Options for Reducing Pain and Disability in Adults With Chronic Low Back Pain: Pilates, Strength, Core-Based, and Mind-Body. A Network Meta-analysis

OBJECTIVE

To determine which type of exercise is best for reducing pain and disability in adults with chronic low back pain (LBP).

DESIGN

Systematic review with a network meta-analysis (NMA) of randomized controlled trials (RCTs).

LITERATURE SEARCH

Six electronic databases were systematically searched from inception to July 2021.

STUDY SELECTION CRITERIA

RCTs testing the effects of exercise on reducing self-perceived pain or disability in adults (aged 18-65 years) with chronic LBP.

DATA SYNTHESIS

We followed the PRISMA-NMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses, incorporating NMAs of health care interventions) statement when reporting our NMA. A frequentist NMA was conducted. The probability of each intervention being the most effective was conducted according to surface under the cumulative ranking curve (SUCRA) values.

RESULTS

We included 118 trials (9710 participants). There were 28 head-to-head comparisons, 7 indirect comparisons for pain, and 8 indirect comparisons for disability. Compared with control, all types of physical exercises were effective for improving pain and disability, except for stretching exercises (for reducing pain) and the McKenzie method (for reducing disability). The most effective interventions for reducing pain were Pilates, mind-body, and core-based exercises. The most effective interventions for reducing disability were Pilates, strength, and core-based exercises. On SUCRA analysis, Pilates had the highest likelihood for reducing pain (93%) and disability (98%).

CONCLUSION

Although most exercise interventions had benefits for managing pain and disability in chronic LBP, the most beneficial programs were those that included (1) at least 1 to 2 sessions per week of Pilates or strength exercises; (2) sessions of less than 60 minutes of core-based, strength, or mind-body exercises; and (3) training programs from 3 to 9 weeks of Pilates and core-based exercises.

More than one third of clinical practice guidelines on low back pain overlap in AGREE II appraisals. Research wasted?

Background

Systematic reviews can apply the Appraisal of Guidelines for Research & Evaluation (AGREE) II tool to critically appraise clinical practice guidelines (CPGs) for treating low back pain (LBP); however, when appraisals differ in CPG quality rating, stakeholders, clinicians, and policy-makers will find it difficult to discern a unique judgement of CPG quality. We wanted to determine the proportion of overlapping CPGs for LBP in appraisals that applied AGREE II. We also compared inter-rater reliability and variability across appraisals.

Methods

For this meta-epidemiological study we searched six databases for appraisals of CPGs for LBP. The general characteristics of the appraisals were collected; the unit of analysis was the CPG evaluated in each appraisal. The inter-rater reliability and the variability of AGREE II domain scores for overall assessment were measured using the intraclass correlation coefficient and descriptive statistics.

Results

Overall, 43 CPGs out of 106 (40.6%) overlapped in seventeen appraisals. Half of the appraisals (53%) reported a protocol registration. Reporting of AGREE II assessment was heterogeneous and generally of poor quality: overall assessment 1 (overall CPG quality) was rated in 11 appraisals (64.7%) and overall assessment 2 (recommendation for use) in four (23.5%). Inter-rater reliability was substantial/perfect in 78.3% of overlapping CPGs. The domains with most variability were Domain 6 (mean interquartile range [IQR] 38.6), Domain 5 (mean IQR 28.9), and Domain 2 (mean IQR 27.7).

Conclusions

More than one third of CPGs for LBP have been re-appraised in the last six years with CPGs quality confirmed in most assessments. Our findings suggest that before conducting a new appraisal, researchers should check systematic review registers for existing appraisals. Clinicians need to rely on updated CPGs of high quality and confirmed by perfect agreement in multiple appraisals.

Pain Science Education Plus Exercise Therapy in Chronic Nonspecific Spinal Pain: A Systematic Review and Meta-analyses of Randomized Clinical Trials

Exercise therapy and education are recommended from several guidelines for managing symptoms in chronic nonspecific spinal pain (CNSP) patients. However, no systematic reviews have previously analyzed the effectiveness of pain science education (PSE) plus exercise therapy for managing CNSP related symptoms. Systematic searches were conducted on 10 databases looking for randomized control trials (RCTs) aimed to evaluate the effectiveness on pain, disability, kinesiophobia, and catastrophizing. Data were analyzed using random-effects meta-analyses and studies were appraised using the Cochrane ROB tool and GRADE. A total of eight RCTs (n = 622) were included in the qualitative-analysis and five were selected for meta-analysis. PSE plus exercise therapy showed improvements in pain (5RCTs: short-term: SMD: -0.53 [-0.86,-0.2]; 4RCTs: intermediate-term: SMD: -0.57 [-1.01,-0.14]; low quality), disability (4RCTs: short-term: SMD: -0.24 [-0.53,0.05]; 4RCTs: intermediate-term: SMD: -0.93 [-1.08,-0.03]; low-to-very-low quality), kinesiophobia (3RCTs: short-term: SMD: -0.7 [-1.51,0.11]; 4RCTs: intermediate-term: SMD: -0.93 [-1.57,-0.30]; moderate-to-very-low quality), and catastrophizing (2RCTs: short-term: MD: -3.26 points [-6.15,-0.37]; 3RCTs: intermediate-term: MD: -4.94 points [-8.08,-1.81]; low-to-very-low quality) compared to exercise alone. A qualitative-analysis showed improvements in the experimental group compared to multimodal physiotherapy (1RCT; low-to-very-low quality), whereas no clear benefits were reported compared to PSE alone (1RCT; very-low quality) or no intervention (1RCT; very-low quality). There is low to very-low certainty of the evidence suggesting that PSE plus exercise therapy reduces CNSP related-symptoms. PERSPECTIVE: Based on low-quality data from small samples, PSE plus exercise therapy reduces CNSP related symptoms. The evidence requires further investigation due to the limited number of studies with short follow-up periods (CRD42020168968).

Endoplasmic Reticulum Stress: An Emerging Therapeutic Target for Intervertebral Disc Degeneration

Low back pain (LBP) is a global health issue. Intervertebral disc degeneration (IDD) is a major cause of LBP. Although the explicit mechanisms underpinning IDD are unclear, endoplasmic reticulum (ER) stress caused by aberrant unfolded or misfolded proteins may be involved. The accumulation of unfolded/misfolded proteins may result in reduced protein synthesis and promote aberrant protein degradation to recover ER function, a response termed the unfolded protein response. A growing body of literature has demonstrated the potential relationships between ER stress and the pathogenesis of IDD, indicating some promising therapeutic targets. In this review, we summarize the current knowledge regarding the impact of ER stress on the process of IDD, as well as some potential therapeutic strategies for alleviating disc degeneration by targeting different pathways to inhibit ER stress. This review will facilitate understanding the pathogenesis and progress of IDD and highlights potential therapeutic targets for treating this condition.

Health care providers' understanding of self-management support for people with chronic low back pain in Ethiopia: an interpretive description

BACKGROUND

Healthcare providers play a key role in supporting people with chronic low back pain to self-manage their condition. The study aimed at exploring how health care providers understand and conceptualize self-management and how they provide self-management support for people with chronic low back pain in Ethiopia.

METHODS

Health care providers who have supported people with low back pain, including medical doctors and physiotherapists, were approached and recruited from three hospitals in Ethiopia. This study employed an interpretive descriptive approach using semi-structured interviews.

FINDINGS

Twenty-four participants (7 women; 17 men) with a median age of 28 (range 24 to 42) years and a median of 9.5 years (range 1 to 11 years) of helping people with chronic low back pain were interviewed. Seven major themes related to health care providers' understanding of self-management support for people with chronic low back pain in Ethiopia emerged. The findings show that self-management was a new concept to many and health care providers' had a fragmented understanding of self-management. They used or suggested several self-management support strategies to help people with CLBP self-manage their condition without necessarily focusing on enhancing their self-efficacy skills. The participants also discussed several challenges to facilitate self-management support for people with chronic low back pain. Despite the lack of training on the concept, the providers discussed the potential of providing self-management support for people with the condition.

CONCLUSIONS

Self-management was a new concept to health care providers. The providers lack the competencies to provide self-management support for people with chronic low back pain. There is a need to enhance the health care providers' self-management support competencies through training.

Management of cardiovascular disease in women with premature ovarian insufficiency: critical quality appraisal of clinical guidelines and algorithm development

OBJECTIVES

1) To assess the methodological quality of clinical practice guidelines (CPGs) associated with cardiovascular disease (CVD) in women with premature ovarian insufficiency (POI); 2) to formulate an algorithm to foster the implementation of guidelines by clinicians.

METHODS

A systematic search for CPGs in English and Chinese languages published between 2015 and 2020 was conducted. Assessment was conducted by two reviewers respectively via the Appraisal of Guidelines for Research and Evaluation II instrument. The interappraisal agreement was evaluated. Recommendations pertaining to the management of CVD in women with POI were extracted from high-score CPGs and developed into an algorithm, which was refined on the basis of expert feedback.

RESULTS

A total of 14 CPGs were included. Three CPGs were evaluated as "high quality," with five "average" and six considered "low quality." The consistency of agreement between reviewers was considered as substantial agreement to almost perfect agreement (0.72-0.90). The algorithm consisted of three categories: initial evaluation, management, and subsequent monitoring of CVD in POI. Only "management" had recommendations from all three high-quality CPGs.

CONCLUSIONS

The overall methodological quality of most CPGs regarding CVD in women with POI is moderate to poor. A management algorithm with a clear implementation strategy was developed from high-scoring CPGs. Further research is needed to provide evidence-based health care in this field.

Facing the National Recovery and Resilience Plan: Sources of Data, Indicators, and Participatory Strategies in Healthcare and Social Fields

Innovation in governance and services should be the target of the Italian National Recovery and Resilience Plan. Monitoring processes, impacts, and outcomes requires a system of new indicators that are practical to collect. Secondary data sources, their availability, and their information potential should be evaluated, and primary sources should be implemented to supplement traditional disease surveillance. This work highlights the most relevant aspects for bridging the mismatching between complex community needs and current health/social supply and how those aspects could be faced. As a result, we propose a structured multi-phases process for setting the design and functionalities of a cooperative information system, built on the integration between secondary and primary data for informing policies about chronic low back pain (CLBP), a widely recognized determinant of disability and significant economic burden. In particular, we propose the Dress-KINESIS, a tool for improving community capacity development and participation that allows one to freely collect big health and social data and link it to existing secondary data. The system also may be able to monitor how the resources are distributed across different care sectors and suggest how to improve efficiency based on the patient’s CLBP risk stratification. Moreover, it is potentially customizable in other fields of health.

Reliability and validity of the novel self-reported spine functional scale (SSFS) in healthy participants

OBJECTIVES

To develop the novel self-reported spine functional scale (SSFS) and conduct reliability and validity analysis, so that the public can better understand their own spine function in a more simple and scientific way, so as to effectively prevent spinal disorders and improve the quality of life through targeted rehabilitation therapeutic measures.

METHODS

This study was approved by an institutional review board, and all subjects gave informed consent to participate.

RESULTS

(1) Using Spearman correlation analysis to evaluate the content validity, each item was significantly correlated with the total score, and the project design was reasonable. The exploratory factor analysis method is used to evaluate the structural validity of the scale, and the standing position and the lying position of the posture evaluation can be attributed to the factor 2, which is called posture evaluation: the cervical flexor strength, the flat support, the prone back, and the supine knee. The back arch of the wall and the angel on the wall is attributed to factor 1, called the overall spine function test, and the cumulative contribution rate of the two factors was 46.057%. Confirmatory factor analysis showed that the two-factor model fits well (χ2/df = 2.440, RMSEA = 0.04 < 0.05, GFI = 0.945, AGFI = 0.920, CFI = 0.967, IFI = 0.967, TLI = 0.951, GFI, AGFI, CFI, IFI, and TLI are > 0.90) and the validity is ideal. (2) The test-retest reliability shows that the test-retest reliability of each entry, each dimension, and the total score is greater than 0.5, and the test-retest reliability is high. The Cronbach α coefficient was used to evaluate the overall internal consistency of the scale, α > 0.70, indicating that the scale has high reliability. After deleting each item one by one, the α coefficient is 0.692-0.717, and there is no significant increase. (3) Sex and occupation did not affect the level of spinal function (P > 0.05), and there was interaction. Different BMI levels significantly affected the score of spinal function (P < 0.05). The rate of spinal dysfunction in overweight and obese subjects was significantly higher than the normal group; the overall score of spinal function was worse than the normal group.

DISCUSSION

The reliability and validity analyses of this study verified the reliability and scientificity of SSFS in the young healthy population. Body weight had a significant influence on SSFS score, and the performance levels were different for the two sexes.

CONCLUSION

The novel Self-Reported Spine Functional Scale (SSFS) has high reliability and validity and is applicable to the self-assessment and maintenance of spinal health and the prevention of related spinal disorders in the young healthy population. Body weight has a significant influence on the SSFS score in healthy young people. Overweight and obese males were found to be more likely to have spinal dysfunction, while underweight males displayed poor cervical flexor muscle strength. Underweight females were found to have better overall spinal function and stronger cervical flexor muscle strength.

Recommendations for Diagnosis and Treatment of Lumbosacral Radicular Pain: A Systematic Review of Clinical Practice Guidelines

The management of patients with lumbosacral radicular pain (LRP) is of primary importance to healthcare professionals. This study aimed to: identify international clinical practice guidelines on LRP, assess their methodological quality, and summarize their diagnostic and therapeutic recommendations. A systematic search was performed (August 2019) in MEDLINE, PEDro, National Guideline Clearinghouse, National Institute for Health and Clinical Excellence (NICE), New Zealand Guidelines Group (NZGG), International Guideline Library, Guideline central, and Google Scholar. Guidelines presenting recommendations on diagnosis and/or treatment of adult patients with LRP were included. Two independent reviewers selected eligible guidelines, evaluated quality with Appraisal of Guidelines Research & Evaluation (AGREE) II, and extracted recommendations. Recommendations were classified into 'should do', 'could do', 'do not do', or 'uncertain'; their consistency was labelled as 'consistent', 'common', or 'inconsistent'. Twenty-three guidelines of varying quality (AGREE II overall assessment ranging from 17% to 92%) were included. Consistent recommendations regarding diagnosis are ('should do'): Straight leg raise (SLR) test, crossed SLR test, mapping pain distribution, gait assessment, congruence of signs and symptoms. Routine use of imaging is consistently not recommended. The following therapeutic options are consistently recommended ('should do'): educational care, physical activity, discectomy under specific circumstances (e.g., failure of conservative treatment). Referral to a specialist is recommended when conservative therapy fails or when steppage gait is present. These recommendations provide a clear overview of the management options in patients with LRP.

Resolving the Burden of Low Back Pain in Military Service Members and Veterans (RESOLVE): Protocol for a Multisite Pragmatic Clinical Trial

BACKGROUND

Physical therapy (PT) is frequently used for the management of low back pain (LBP) within the US Departments of Defense (DOD) and Veterans Affairs (VA). However, variations in PT practice patterns and use of ineffective interventions lower the quality and increase the cost of care. Although adherence to the clinical practice guidelines (CPGs) can improve the outcomes and cost-effectiveness of LBP care, PT CPG adherence remains below 50%. The Resolving the Burden of Low Back Pain in Military Service Members and Veterans (RESOLVE) trial will evaluate the effectiveness of an active PT CPG implementation strategy using an education, audit, and feedback model for reducing pain, disability, medication use, and cost of LBP care within the DOD and VA health care systems.

DESIGN

The RESOLVE trial will include 3,300 to 7,260 patients with LBP across three DOD and two VA medical facilities using a stepped-wedge study design. An education, audit, and feedback model will be used to encourage physical therapists to better adhere to the PT CPG recommendations. The Oswestry Disability Index and the Defense and Veterans Pain Rating Scale will be used as primary outcomes. Secondary outcomes will include the LBP-related medication use, medical resource utilization, and biopsychosocial predictors of outcomes. Statistical analyses will be based on the intention-to-treat principle and will use linear mixed models to compare treatment conditions and examine the interactions between treatment and subgrouping status (e.g., limb loss).

SUMMARY

The RESOLVE trial will provide a pragmatic approach to evaluate whether better adherence to PT CPGs can reduce pain, disability, medication use, and LBP care cost within the DOD and VA health care systems.

Are clinical practice guidelines for low back pain interventions of high quality and updated? A systematic review using the AGREE II instrument

BACKGROUND

Clinical practice guidelines (CPGs) provide recommendations for practice, but the proliferation of CPGs issued by multiple organisations in recent years has raised concern about their quality. The aim of this study was to systematically appraise CPGs quality for low back pain (LBP) interventions and to explore inter-rater reliability (IRR) between quality appraisers. The time between systematic review search and publication of CPGs was recorded.

METHODS

Electronic databases (PubMed, Embase, PEDro, TRIP), guideline organisation databases, websites, and grey literature were searched from January 2016 to January 2020 to identify GPCs on rehabilitative, pharmacological or surgical intervention for LBP management. Four independent reviewers used the Appraisal of Guidelines for Research and Evaluation II (AGREE II) tool to evaluate CPGs quality and record the year the CPGs were published and the year the search strategies were conducted.

RESULTS

A total of 21 CPGs met the inclusion criteria and were appraised. Seven (33%) were broad in scope and involved surgery, rehabilitation or pharmacological intervention. The score for each AGREE II item was: Editorial Independence (median 67%, interquartile range [IQR] 31-84%), Scope and Purpose (median 64%, IQR 22-83%), Rigour of Development (median 50%, IQR 21-72%), Clarity and Presentation (median 50%, IQR 28-79%), Stakeholder Involvement (median 36%, IQR 10-74%), and Applicability (median 11%, IQR 0-46%). The IRR between the assessors was nearly perfect (interclass correlation 0.90; 95% confidence interval 0.88-0.91). The median time span was 2 years (range, 1-4), however, 38% of the CPGs did not report the coverage dates for systematic searches.

CONCLUSIONS

We found methodological limitations that affect CPGs quality. In our opinion, a universal database is needed in which guidelines can be registered and recommendations dynamically developed through a living systematic reviews approach to ensure that guidelines are based on updated evidence.
