Pilates for low back pain

Appropriateness of exercise therapy delivery in chronic low back pain management: cross-sectional online survey of physiotherapy practice in Germany

BACKGROUND

In Germany, exercise therapy represents the most commonly prescribed physiotherapy service for non-specific, chronic low back pain (NSCLBP). So far, little is known about current practice patterns of German physiotherapists in delivering this intervention. Thus, the aim of this study was to investigate the appropriateness of exercise therapy delivered to NSCLBP patients in German physiotherapy care and to identify practitioner-related drivers of appropriate exercise delivery.

METHODS

We used a vignette-based, exploratory, cross-sectional, online-survey study design (76-items; data collection between May and July 2023). Eligible participants were required to hold a professional degree in physiotherapy and were required to be practicing in Germany. Access links to anonymous online surveys were spread via established German physiotherapy networks, educational platforms, social media, e-mail lists, and snowball sampling. Appropriateness of exercise therapy was calculated by an equally weighted total score (400 points) including scales on shared-decision-making, exercise dose selection, pain knowledge and self-management promotion. "Appropriate exercise delivery" was determined by a relative total score achievement of > 80%. "Partly appropriate exercise delivery" was determined by a relative total score achievement of 50-79%, and "inappropriate exercise delivery" by a score achievement of < 50%. Practitioner-related drivers of exercise appropriateness were calculated by bivariate and multiple linear regression analyses.

RESULTS

11.9% (N = 35) of 298 physiotherapists' exercise delivery was considered "appropriate", 83.3% (N = 245) was "partly appropriate", and 4.8% (N = 14) was "inappropriate". In the final multiple regression model, most robust parameters positively influencing appropriate delivery of exercise therapy were increased scientific literacy (B = 10.540; 95% CI [0.837; 20.243]), increased average clinical assessment time (B = 0.461; 95% CI [0.134; 0.789]), increased self-perceived treatment competence (B = 7.180; 95% CI [3.058; 11.302], and short work experience (B = - 0.520; 95% CI [-0.959; - 0.081]).

CONCLUSION

Appropriate exercise delivery in NSCLBP management was achieved by only 11.9% of respondents. However, the vast majority of 95.2% of respondents was classified to deliver exercise therapy partly appropriate. Long work experience seemed to negatively affect appropriate exercise delivery. Positive influences were attributed to scientific literacy, the average clinical assessment time per patient as well as the perceived treatment competence in NSCLBP management.

Effects of pilates exercises on radiographic lumbo-pelvic alignment and range of motion in non-specific low back pain patients

OBJECTIVES

To determine the effects of Pilates exercises on lumbo-pelvic alignment in non-specific low back pain (NSLBP) patients.

METHODS

Twenty-two patients (Male:7; Female:15) with NSLBP aged 20-65 years were recruited and classified based on a modified O'Sullivan's classification system into flexion pattern (FP) or active extension pattern (EP) groups. Oswestry Disability index (ODI), Roland-Morris Disability Questionnaire (RMDQ) as well as radiographic lumbar global range of motion (ROM) and lumbo-pelvic alignment were measured Pre- and immediately post-intervention and at 6- and 12-month. The intervention included supervised six-weeks Pilates program with 60 min per session and up to two sessions per week.

RESULTS

Lumbar lordosis, sacral slope and sacral inclination were found to be significantly different between the FP and EP groups based on the O'Sullivan's classification system. However, despite the significant changes in RMDQ (p = 0.001), no significant changes were found for any of the alignment parameters (p > 0.05) post intervention for both groups. For lumbar global ROM, a statistically significant change was observed for the EP group (p = 0.028) but not for the FP group (p = 0.249). No significant correlations were identified between any of the self-reported outcomes, radiographic alignment and ROM parameters.

CONCLUSIONS

Patients self-perceived long-term functional improvements based on responding to questionnaires after Pilates exercises were not reflected in significant changes in lumbo-pelvic alignment or lumbar ROM. This may be due to the current cohort demonstrating within normal ranges due to the lesser severity of their condition, but further research is needed for clarification.

Remote Pilates Training Is Effective in Improving Physical Fitness in Healthy Women: A Randomized Controlled Study

Despite its positive impact on physical and mental well-being, adults may refrain from performing regular physical activity, due to inadequate time, accessibility, or funds. Yet remote platforms could overcome such obstacles and increase participation. This study evaluated the effectiveness of remote-synchronous group-Pilates classes compared to in-studio classes in healthy sedentary women. In a randomized controlled design, 40 women, aged 20-45, were assigned to a Zoom or studio group-Pilates training. The intervention included twice-weekly 45 min sessions over an eight-week period. Attendance (adherence) was recorded, and the participants completed physical motor tests (plank, curl-up, stork, push-up, and V-sit and reach), Profile of Mood State Surveys, and Nordic Musculoskeletal Pain Questionnaires. Evaluations were performed at baseline, mid-intervention (4 weeks), and post intervention (8 weeks). Adherence to training was high in the Zoom and studio groups (80% and 74%, respectively). Improvements in physical motor tests were seen in both groups following the Pilates interventions, thereby indicating the effectiveness of group-Pilates Zoom training. In conclusion, remote online physical activity such as Pilates offers a good alternative to in-studio trainings, as a means for improving physical fitness and promoting a healthy lifestyle in adults, by offering a more accessible and less timely alternative to in-studio physical activity programs.

The effect of a six-week Aqua Pilates and Aqua Stretch intervention on pain, function, and quality of life in patients affected by ankylosing spondylitis: A rater-blind randomized controlled trial

BACKGROUND

There has been a dearth of research into the benefits of water-based workouts for ankylosing spondylitis (AS) patients.

OBJECTIVE

This study aimed to compare the effect of Aqua Stretch and Aqua Pilates in improving quality of life (QOL), function, and pain in AS patients.

METHODS

This study was conducted on 40 patients, who were randomly assigned to the Aqua Pilates, Aqua Stretch, and control groups. The experimental groups attended interventions for six-week. QOL, pain intensity, function, and fatigue were measured before and after treatments.

RESULTS

Except for the chest expanding, all variables in the Aqua Stretch group changed significantly after six weeks (p< 0.05). QOL (p= 0.002), 6MWT (p= 0.016), and Schober flexion (p= 0.011) showed changes, while BASDAI (p= 0.0001), VAS (p= 0.0001), fatigue (p= 0.0001), and Schober extension (p= 0.028) showed significant decreases. Except for chest expansion and Schober extension, which did not alter significantly after six-week of Aqua Pilates (p> 0.05), all other variables did. There was an increasing trend in 6MWT and Schober flexion (p= 0.021) and a decreasing trend in BASDAI (p= 0.002), VAS (p= 0.0001) and fatigue (p= 0.002). Except for QOL (p= 0.016), no statistically significant differences were found between the groups.

CONCLUSION

All variables had a significant change after six-week Aqua Stretch, except for the chest expanding. Chest expanding and Schober extension were the variables which had no significant change after six-week Aqua Pilates. With the exception of QOL, no statistically significant differences were found between the groups. Aqua Stretch had the greatest effect on the VAS, as measured by the minimum clinically relevant differences (MCID). Moreover, in Aqua Stretch alone, there was a notable impact on fatigue, QOL, and the BASDAI.

Rehabilitation therapy using the HUBER platform in chronic non-specific low back pain: a randomized controlled trial

BACKGROUND

Non-specific chronic low back pain (NSCLBP) refers to a complex condition that involves structural, biomechanical, cognitive, psychological, social, and lifestyle issues. First-line therapies include physical therapy and exercise, as well as psychological follow-up and pain medication.

AIM

The aim of this study was to assess the impact of a 6-week center-based program using a multi-axis motorized platform (HUBER) connected with force sensors, that allows the patients to execute isometric exercises on the spine flexion-to-extension ratio at 60 and 120°/s, pain, trunk flexibility, and disability.

DESIGN

The design of the study was prospective, active control, parallel-group, assessor-blinded, randomized controlled trial.

SETTING

The setting was outpatients physical therapy clinic.

POPULATION

The population analyzed presented NSCLBP.

METHODS

Seventy individuals with NSCLBP were randomized into 2 intervention arms (1:1 ratio): 1/standard rehabilitation group (STAND) with physiotherapy, balneotherapy and cycloergometer exercises and 2/HUBER rehabilitation group (HUB) with physiotherapy, balneotherapy and HUBER exercises. Both programs lasted 6 weeks, with 4 sessions of 2 hours each per week.

RESULTS

Each group reported statistically significant improvements on the isokinetic spine strength, flexibility of the trunk, lumbar joint mobility, muscular endurance of the trunk and of the lower limbs, pain score and disability (P<0.05). The spine flexion/extension ratio at 60˚/s improved similarly between groups (-22.23 for HUB, and -13.04 for STAND; P=0.178) with a greater effect size in HUB. Only HUB reported a significant improvement in the spine flexion-to-extension ratio at 120˚/s (from 87.3 to 78.6, P=0.012). HUB reported a greater decrease in the Oswestry Disability Index (-16.83) compared to STAND (-12.11), with a statistically significant effect between groups (P=0.036).

CONCLUSIONS

Exercises performed on the HUBER platform added to physiotherapy and balneotherapy are as effective as a standard rehabilitation program with physiotherapy, balneotherapy and cycloergometer exercises to improve isokinetic spine strength, lumbar joint mobility, flexibility and muscular endurance of the trunk and the lower limbs. In addition, exercising with the HUBER platform result in a greater reduction in disability compared to a standard rehabilitation program (clinicalTrials.gov: NCT05437016).

CLINICAL REHABILITATION IMPACT

A variety of intervention techniques, including supervised exercise and manual therapy are now used to manage persistent NSCLBP. The added value of the HUBER device on disability suggests that the platform could be beneficial.

Exergames in Older Adult Community Centers and Nursing Homes to Improve Balance and Minimize the Risk of Falls in Older Adults: A Systematic Review and Meta-Analysis

There is a substantial gap in our knowledge regarding the efficacy of exergames on the reduction of fall risk in older adults. This systematic review analyzes the findings of clinical trials describing the efficacy of exergames to improve balance or reduce the risk of falls in individuals above 60 years of age who are residents in community centers or nursing homes. We searched Google Scholar, PubMed, and Embase up to January 2023. Initially, 52,294 records were screened. After applying the inclusion and exclusion criteria, 20 studies were included in this systematic review. Meta-analyses revealed statistically significant reductions in the risk of falls and improvements in balance. Exergaming tended to produce positive benefits according to the results obtained using different instruments (TUG, PPA, BBS, and others), control groups, and times of intervention. Nevertheless, a substantial proportion of studies exhibited a high risk of bias and only one had a long follow-up period. Although a large body of evidence supports the view that exergaming is suitable for reducing fall risk and improving balance in older adults, some gaps remain in our knowledge about such benefits.

Pilates to Improve Core Muscle Activation in Chronic Low Back Pain: A Systematic Review

Low back pain is prevalent in the community and associated with deficits in core muscle strength and activation. Pilates is argued to improve movement and reduce pain, yet there is a limited understanding of the specific effects of Pilates training on core muscle strength or activity. A systematic search of databases (CINAHL, Embase, Ovid MEDLINE) used Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methods to evaluate randomised controlled trials (RCTs) on the effects of Pilates to improve core muscle activation. Methodological quality was assessed using the Physiotherapy Evidence Database scale (PEDro). The certainty of findings was determined using the Grading of Recommendations Assessment, Development and Evaluation tool. Of the initial yield of 563 articles, eight RCTs met the inclusion criteria. A diverse range of Pilates interventions and outcome measures were utilised to assess effects on core muscle activation and strength. The main finding was that Pilates is not inferior to equivalently dosed exercises, and can be superior to non-equivalent or no exercise, for improving core muscle strength as indicated by muscle thickness. There was emerging evidence that Pilates positively impacts core muscle strength and can be an effective intervention for people living with chronic low back pain.

The core symptom in multiple myeloma patients undergoing chemotherapy: a network analysis

BACKGROUND

During chemotherapy for multiple myeloma, symptoms include those related to the disease, as well as adverse effects of the treatment. Few studies have explored the relationships between these symptoms. Network analysis could identify the core symptom in the symptom network.

OBJECTIVE

The aim of this study was to explore the core symptom in multiple myeloma patients undergoing chemotherapy.

METHODS

This was a cross-sectional study in which sequential sampling was used to recruit 177 participants from Hunan, China. Demographic and clinical characteristics were surveyed using a self-developed instrument. The symptoms of chemotherapy-treated multiple myeloma, including pain, fatigue, worry, nausea, and vomiting, were measured using a questionnaire with good reliability and validity. The mean ± SD, frequency, and percentages were used as descriptive statistics. Network analysis was used to estimate the correlation between symptoms.

RESULTS

The results showed that 70% of multiple myeloma patients using chemotherapy exhibited pain. In the network analysis, worrying was the dominant symptom, and the strongest relationship was between nausea and vomiting in chemotherapy-treated multiple myeloma patients' symptoms.

CONCLUSION

Worrying is the core symptom of multiple myeloma patients. Interventions could be most effective if there is a symptom management focus on worrying when providing care to chemotherapy-treated multiple myeloma patients. Nausea combined with vomiting could be better managed, which would decrease the cost of health care. Understanding the relationship between the symptoms of multiple myeloma patients undergoing chemotherapy is beneficial for precise symptom management.

IMPLICATIONS FOR PRACTICE

Nurses and health care teams should be a priority to intervene in the worrying for chemotherapy-treated multiple myeloma patients to maximize the effectiveness of an intervention. Except, nausea and vomiting should be managed together in a clinical setting.

The effects of Pilates exercise in comparison to other forms of exercise on pain and disability in individuals with chronic non-specific low back pain: A systematic review with meta-analysis

OBJECTIVE

To compare the effects of Pilates exercise (PE) with other forms of exercise on pain and disability in individuals with chronic non-specific low back pain (CNSLBP) and to inform clinical practice and future research.

STUDY DESIGN

Systematic review with meta-analysis conducted and reported in line the Preferred Reporting Items for Systematic review and Meta-analysis.

LITERATURE SEARCH

Six electronic databases were searched from inception to April 2021.

STUDY SELECTION CRITERIA

Randomised controlled trials (RCTs) comparing the effect of PE with other forms of exercise for adults with CNSLBP on pain and disability.

DATA SYNTHESIS

Two reviewers assessed the risk of bias of the trials, guided by the Cochrane RoB2 tool. Available data were extracted for meta-analysis with subgroup analysis. Pilates exercise was compared to general exercise (GE), direction-specific exercise (DSE) and spinal stabilisation exercise (SSE). Certainty of evidence was interpreted following the Grading of Recommendations Assessment, Development and Evaluation approach.

RESULTS

Eleven RCTs were included. A low certainty of evidence supported PE was more effective than GE in pain reduction [Effect size (ES) 0.44]. Moreover, very low levels of certainty were revealed for effectiveness of PE compared with DSE for pain reduction (ES 0.65) and equivalence of PE and SSE for pain and disability.

CONCLUSIONS

This review found no strong evidence for using one type of exercise intervention over another when managing patients with CNSLBP. Existing evidence does not allow this review to draw definitive recommendations. In the absence of a superior exercise form clinicians should work collaboratively with the patient, using the individual's goals and preferences to guide exercise selection. Further appropriately designed research is warranted to explore this topic further.

Effectiveness of a Group-Based Rehabilitation Program Combining Education with Multimodal Exercises in the Treatment of Patients with Nonspecific Chronic Low Back Pain: A Retrospective Uncontrolled Study

Currently, there is no consensus on the best rehabilitation program to perform for nonspecific chronic low back pain (NSCLBP). However, multimodal exercises, education, and group-based sessions seem to be beneficial. We, therefore, launched such a treatment program and aimed to evaluate its effectiveness in improving patient health status. We retrospectively analyzed the records of 23 NSCLB patients who followed the MyBack program at La Tour hospital from 2020 to 2022 (25 sessions, 8 weeks). Patients were evaluated before and after intervention using pain on a visual analog scale (pVAS), Roland−Morris Disability Questionnaire (RMDQ), Pain Catastrophizing Scale (PCS), Tampa Scale of Kinesiophobia (TSK), and the EuroQol-5D-3L (EQ-5D-3L). Responder rates were calculated using minimal clinically important differences. Patients reported a significant reduction (p < 0.05) in the pVAS (5.3 ± 1.2 vs. 3.1 ± 1.6), RMDQ (8.8 ± 3.3 vs. 4.0 ± 3.7), PCS (24.5 ± 9.4 vs. 11.7 ± 7.9) and TSK (41.5 ± 9.2 vs. 32.7 ± 7.0). The EQ-5D-3L also statistically improved (score: 0.59 ± 0.14 vs. 0.73 ± 0.07; and VAS: 54.8 ± 16.8 vs. 67.0 ± 15.2). The responder rates were 78% for the pVAS and PCS, 74% for the RMDQ and TSK, and only 26% for the EQ-5D-3L. The MyBack program combining education with multimodal group exercises led to satisfactory clinical, functional, and psychosocial outcomes.

Comparative efficacy and acceptability of non-pharmacological interventions in fibromyalgia: Protocol for a network meta-analysis

INTRODUCTION

Although several non-pharmacological interventions have been tested in the management of Fibromyalgia (FM), there is little consensus regarding the best options for the treatment of this health condition. The purpose of this network meta-analysis (NMA) is to investigate the comparative efficacy and acceptability of non-pharmacological interventions for FM, in order to assist clinical decision making through a ranking of interventions in relation to the most important clinical outcomes in these patients.

METHODS AND ANALYSIS

We will perform a systematic search to identify randomised controlled trials of non-pharmacological interventions endorsed in guidelines and systematic reviews. Information sources searched will include major bibliographic databases without language or date restrictions (MEDLINE, Cochrane Library, EMBASE, AMED, PsycINFO and PEDro). Our primary outcomes will be pain intensity, patient-reported quality of life (QoL), and acceptability of treatment will be our secondary outcome. Risk of bias of the included trials will be assessed using the Cochrane risk of bias tool (RoB2). For each pairwise comparison between the different interventions, we will present mean differences (MDs) for pain intensity and QoL outcomes and Relative Risks (RRs) for acceptability, both with respective 95% confidence intervals (CIs). Initially, standard pairwise meta-analyses will be performed using a DerSimonian-Laird random effects model for all comparisons with at least two trials and then we will perform a frequentist NMA using the methodology of multivariate meta-analysis assuming a common heterogeneity parameter, using the mvmeta command and network suite in STATA. In the NMA, two different types of control group, such as placebo/sham and no intervention/waiting list will be combined as one node called "Control". The competing interventions will be ranked using the P-score, which is the frequentist analogue of surface under the cumulative ranking curve (SUCRA) for the outcomes of interest at immediate- (intervention duration of up to 2 weeks), short- (over 2 weeks up to 12 weeks) and long-terms (over 12 weeks). The confidence in the results from NMA will be assessed using the Confidence in Network Meta-analysis (CINeMA) framework.

ETHICS AND DISSEMINATION

This work synthesises evidence from previously published studies and does not require ethics review or approval. A manuscript describing the findings will be submitted for publication in a peer-reviewed scientific journal.

Summarizing the effects of different exercise types in chronic low back pain - a systematic review of systematic reviews

Background

In chronic LBP (CLBP), guideline-endorsed treatment is to stay active, return to normal activity, and to exercise. Several reviews on various exercise types used in CLBP have been published. We aimed to identify systematic reviews of common exercise types used in CLBP, to appraise their quality, and to summarize and compare their effect on pain and disability.

Methods

We searched the databases OVID MEDLINE, EMBASE, COCHRANE LIBRARY, and WEB OF SCIENCE (Core collection) for systematic reviews and meta-analyses on adults between 18 and 70 years of age suffering from chronic or recurrent LBP for a period of at least 12 weeks, which investigated the effects of exercises on pain and disability. All searches were conducted without language restriction. The search was performed up until 2022–01-26. The included reviews were grouped into nine exercise types: aerobic training, aquatic exercises, motor control exercises (MCE), resistance training, Pilates, sling exercises, traditional Chinese exercises (TCE), walking, and yoga. The study quality was assessed with AMSTAR-2. For each exercise type, a narrative analysis was performed, and the level of evidence for the effects of exercise was assessed through GRADE.

Results

Our database search resulted in 3,475 systematic reviews. Out of the 253 full texts that were screened, we included 45 systematic reviews and meta-analyses. The quality of the included reviews ranged from high to critically low. Due to large heterogeneity, no meta-analyses were performed. We found low-to-moderate evidence of mainly short-term and small beneficial effects on pain and disability for MCE, Pilates, resistance training, TCE, and yoga compared to no or minimal intervention.

Conclusions

Our findings show that the effect of various exercise types used in CLBP on pain and disability varies with no major difference between exercise types. Many of the included systematic reviews were of low-to-moderate quality and based on randomized controlled trials with high risk of bias. The conflicting results seen, undermine the certainty of the results leading to very-low-to-moderate quality of evidence for our results. Future systematic reviews should be of higher quality to minimize waste of resources.

Effects of an Intensive 6-Week Rehabilitation Program with the HUBER Platform in the Treatment of Non-Specific Chronic Low Back Pain: A Pilot Study

Non-specific chronic low back pain (NSCLBP) is defined as a complex disorder involving structural, biomechanical, cognitive, psychological, social, and lifestyle factors. Non-pharmacological approaches such as exercise and physical therapy have been proposed in first-line treatments, along with psychological follow-up and pain medication if needed. Our objective was to evaluate the effectiveness of an intensive rehabilitation program with HUBER (a multi-axis motorized platform equipped with force sensors, allowing patients to perform physical exercises in an isometric mode) on the spine flexion-to-extension ratio at 60 and 120°/s, pain, and trunk flexibility in individuals with NSCLBP. Twelve participants underwent a clinical evaluation including isokinetic spine strength and participated in a 6-week rehabilitation program with HUBER 360 Evolution. The main findings of this pilot study show that the flexor/extensor ratios at 60°, the flexibility of the hamstring and quadriceps, and muscular endurance of the trunk, disability, and quality of life were significantly improved at the end of the rehabilitation program (p < 0.05). Low back pain and analgesic medication were also reduced. Exercising with the HUBER Platform seems to be effective in managing NSCLBP but a randomized study with a larger sample size and a control group is necessary.

A Systematic Review of the Effectiveness of Core Stability Exercises in Patients with Non-Specific Low Back Pain

Background

Low back pain affects millions of people worldwide and can be a difficult condition to manage clinically. Many cases do not have a discernable etiology, further increasing the complexity of finding an effective intervention. Core stabilization exercises (CSE) strengthen the musculature that provides stability to the spine and show promising outcomes.

Purpose

To examine the efficacy of CSE exercises in the treatment of NSLBP in adult patients.

Study Selection

Studies were included if they had patients diagnosed with NSLBP, used CSE as a treatment for NSLBP, and were a clinical trial. Exclusion criteria were studies that did not utilize an objective pain scale, patients who had a specific diagnosed pathology contributing to the NSLBP or received treatment for their NSLBP within the prior six months.

Methods

The literature was systematically searched in the PubMed, Sports Medicine & Education Index, and CINHAL databases, using the search terms core stabilization, low back pain, and exercise. The initial search yielded 229 articles and was refined using search terms 'NOT analysis' in order to target randomized control trials and exclude meta-analyses to narrow the search. Full-text of the articles were assessed for eligibility by utilizing inclusion and exclusion criteria that were included in this review. Articles were assessed for quality using the PEDro scale and relevant data were extracted.

Results

Five moderate-quality studies (PEDRO range: 5-8) support CSE is an effective method to decrease pain, improve functionality, and increase core strength in patients with NSLBP. Although there are other commonly used methods to treating NSLBP, CSE have shown to be a beneficial method to treating NSLBP.

Conclusion

Grade B evidence suggests core stabilization exercises can be considered a favorable method for treating pain in patients with NSLBP.

Making exercise count: Considerations for the role of exercise in back pain treatment

INTRODUCTION

Chronic low back pain (CLBP) is pain that has persisted for greater than three months. It is common and burdensome and represents a significant proportion of primary health presentations. For the majority of people with CLBP, a specific nociceptive contributor cannot be reliably identified, and the pain is categorised as 'non-specific'. Exercise therapy is recommended by international clinical guidelines as a first-line treatment for non-specific CLBP.

AIM

This comprehensive review aims to synthesise and appraise the current research to provide practical, evidence-based guidance concerning exercise prescription for non-specific CLBP. We discuss detailed initial assessment and being informed by patient preferences, values, expectations, competencies and goals.

METHODS

We searched the Cochrane Database of Systematic Reviews, PubMed and the Physiotherapy Evidence Database (PEDro) using broad search terms from January 2000 to March 2021, to identify the most recent clinical practice guidelines, systematic reviews and randomised controlled trials on exercise for CLBP.

RESULTS/DISCUSSION

Systematic reviews show exercise is effective for small, short-term reductions in pain and disability, when compared with placebo, usual care, or waiting list control, and serious adverse events are rare. A range of individualised or group-based exercise modalities have been demonstrated as effective in reducing pain and disability. Despite this consensus, controversies and significant challenges remain.

CONCLUSION

To promote recovery, sustainable outcomes and self-management, exercise can be coupled with education strategies, as well as interventions that enhance adherence, motivation and patient self-efficacy. Clinicians might benefit from intentionally considering their own knowledge and competencies, potential harms of exercise and costs to the patient. This comprehensive review provides evidence-based practical guidance to health professionals who prescribe exercise for people with non-specific CLBP.

Some types of exercise are more effective than others in people with chronic low back pain: a network meta-analysis

QUESTION

What are the effects of specific types of exercise treatments on pain intensity and functional limitation outcomes for adults with chronic low back pain?

DESIGN

Systematic review with network meta-analysis of randomised controlled trials.

PARTICIPANTS

Adults with non-specific low back pain for ≥ 12 weeks.

INTERVENTION

Exercise treatments prescribed or planned by a health professional that involved conducting specific activities, postures and/or movements with a goal to improve low back pain outcomes.

OUTCOME MEASURES

Pain intensity (eg, visual analogue scale or numerical rating scale) and back-related functional limitations (eg, Roland Morris Disability Questionnaire or Oswestry Disability Index), each standardised to range from 0 to 100.

RESULTS

This review included 217 randomised controlled trials with 20,969 participants and 507 treatment groups. Most exercise types were more effective than minimal treatment for pain and functional limitation outcomes. Network meta-analysis results were compatible with moderate to clinically important treatment effects for Pilates, McKenzie therapy, and functional restoration (pain only) and flexibility exercises (function only) compared with minimal treatment, other effective treatments and other exercise types. The estimated mean differences for these exercise types compared with minimal treatment ranged from -15 to -19 for pain and from -10 to -12 for functional limitation.

CONCLUSION

This review found evidence that Pilates, McKenzie therapy and functional restoration were more effective than other types of exercise treatment for reducing pain intensity and functional limitations. Nevertheless, people with chronic low back pain should be encouraged to perform the exercise that they enjoy to promote adherence.

Exercise therapy for chronic low back pain

BACKGROUND

Low back pain has been the leading cause of disability globally for at least the past three decades and results in enormous direct healthcare and lost productivity costs.

OBJECTIVES

The primary objective of this systematic review is to assess the impact of exercise treatment on pain and functional limitations in adults with chronic non-specific low back pain compared to no treatment, usual care, placebo and other conservative treatments.

SEARCH METHODS

We searched CENTRAL (which includes the Cochrane Back and Neck trials register), MEDLINE, Embase, CINAHL, PsycINFO, PEDro, SPORTDiscus, and trials registries (ClinicalTrials.gov and World Health Organization International Clinical Trials Registry Platform), and conducted citation searching of relevant systematic reviews to identify additional studies. The review includes data for trials identified in searches up to 27 April 2018. All eligible trials have been identified through searches to 7 December 2020, but have not yet been extracted; these trials will be integrated in the next update.

SELECTION CRITERIA

We included randomised controlled trials that assessed exercise treatment compared to no treatment, usual care, placebo or other conservative treatment on the outcomes of pain or functional limitations for a population of adult participants with chronic non-specific low back pain of more than 12 weeks' duration.

DATA COLLECTION AND ANALYSIS

Two authors screened and assessed studies independently, with consensus. We extracted outcome data using electronic databases; pain and functional limitations outcomes were re-scaled to 0 to 100 points for meta-analyses where 0 is no pain or functional limitations. We assessed risk of bias using the Cochrane risk of bias (RoB) tool and used GRADE to evaluate the overall certainty of the evidence. When required, we contacted study authors to obtain missing data. To interpret meta-analysis results, we considered a 15-point difference in pain and a 10-point difference in functional limitations outcomes to be clinically important for the primary comparison of exercise versus no treatment, usual care or placebo.

MAIN RESULTS

We included 249 trials of exercise treatment, including studies conducted in Europe (122 studies), Asia (38 studies), North America (33 studies), and the Middle East (24 studies). Sixty-one per cent of studies (151 trials) examined the effectiveness of two or more different types of exercise treatment, and 57% (142 trials) compared exercise treatment to a non-exercise comparison treatment. Study participants had a mean age of 43.7 years and, on average, 59% of study populations were female. Most of the trials were judged to be at risk of bias, including 79% at risk of performance bias due to difficulty blinding exercise treatments. We found moderate-certainty evidence that exercise treatment is more effective for treatment of chronic low back pain compared to no treatment, usual care or placebo comparisons for pain outcomes at earliest follow-up (MD -15.2, 95% CI -18.3 to -12.2), a clinically important difference. Certainty of evidence was downgraded mainly due to heterogeneity. For the same comparison, there was moderate-certainty evidence for functional limitations outcomes (MD -6.8 (95% CI -8.3 to -5.3); this finding did not meet our prespecified threshold for minimal clinically important difference. Certainty of evidence was downgraded mainly due to some evidence of publication bias.  Compared to all other investigated conservative treatments, exercise treatment was found to have improved pain (MD -9.1, 95% CI -12.6 to -5.6) and functional limitations outcomes (MD -4.1, 95% CI -6.0 to -2.2). These effects did not meet our prespecified threshold for clinically important difference. Subgroup analysis of pain outcomes suggested that exercise treatment is probably more effective than education alone (MD -12.2, 95% CI -19.4 to -5.0) or non-exercise physical therapy (MD -10.4, 95% CI -15.2 to -5.6), but with no differences observed for manual therapy (MD 1.0, 95% CI -3.1 to 5.1). In studies that reported adverse effects (86 studies), one or more adverse effects were reported in 37 of 112 exercise groups (33%) and 12 of 42 comparison groups (29%). Twelve included studies reported measuring adverse effects in a systematic way, with a median of 0.14 (IQR 0.01 to 0.57) per participant in the exercise groups (mostly minor harms, e.g. muscle soreness), and 0.12 (IQR 0.02 to 0.32) in comparison groups.

AUTHORS' CONCLUSIONS

We found moderate-certainty evidence that exercise is probably effective for treatment of chronic low back pain compared to no treatment, usual care or placebo for pain. The observed treatment effect for the exercise compared to no treatment, usual care or placebo comparisons is small for functional limitations, not meeting our threshold for minimal clinically important difference. We also found exercise to have improved pain (low-certainty evidence) and functional limitations outcomes (moderate-certainty evidence) compared to other conservative treatments; however, these effects were small and not clinically important when considering all comparisons together. Subgroup analysis suggested that exercise treatment is probably more effective than advice or education alone, or electrotherapy, but with no differences observed for manual therapy treatments.

Exercise interventions can improve muscle strength, endurance, and electrical activity of lumbar extensors in individuals with non-specific low back pain: a systematic review with meta-analysis

Exercise interventions have been recommended for people with non-specific low back pain. The literature is scarce regarding the effects of exercise on muscle strength, endurance, and electrical activity of lumbar extensor muscles. Electronic searches were carried out from May 2020 until August 2020 in the following databases: PUBMED, CENTRAL, EMBASE, PEDro, SPORTDiscus, Scielo, and LILACS. Only randomized controlled trials with passive and active control groups were included. The methodological quality of the included studies was performed using the Physiotherapy Evidence Database Scale. Eight studies, involving 508 participants, were included in metanalytical procedures. Exercise interventions demonstrated superior effects on muscle activity (Electromyography) when compared with active controls (p < 0.0001). Exercise interventions demonstrated superior effects on muscle endurance (Sorensen Test) when compared with passive (p = 0.0340) and active controls (p = 0.0276). Exercise interventions demonstrated superior effects on muscle strength (Machine) when compared with passive controls (p = 0.0092). Exercise interventions can improve muscle strength, endurance, and electrical activity in people with non-specific low back pain.

Complementary and Alternative Modalities (CAM) for pain management in musculoskeletal diseases (MSDs)

Musculoskeletal diseases are a group of clinical conditions affecting the body's movement and remain a common source of pain affecting the quality of life. The aetio-pathological reasons for pain associated with musculoskeletal diseases can be varied and complex. Conventional medicine can treat or modify pain due to musculoskeletal diseases; however, these may be associated with some side effects and at times may not be able to relieve pain completely. These treatment modalities also have ceiling effects like doses of analgesics, the number of nerve blocks, etc. Complementary and Alternative Medicine (CAM) provides a supplementary, unconventional modality to alleviate discomfort and disability associated with these mostly chronic conditions to manage activities of daily living. These modalities have been variedly combined with conventional management for symptom control and thus improve day-to-day activities. We assess the role of commonly used CAM modalities in the management of pain arising from Musculoskeletal diseases.

Relationship between impaired work function and coping behaviors in workers with low back pain

OBJECTIVES

The aim of the present study was to clarify the relationship between work functional impairment levels and three coping behaviors of workers with low back pain, which were about seeking medical attention, taking over-the-counter drugs, and taking self-care.

METHODS

We conducted a cross-sectional study on 14 Japanese companies in 2016. Work function impairment was measured using the Work Functioning Impairment Scale. Logistic regression analyses were conducted for the three coping behaviors and odds ratios (ORs) calculated for work functional impairment levels.

RESULTS

We analyzed 2232 subjects; 226 were women and 790 worked on production lines. 688 workers had sought medical attention, 436 had taken over-the-counter medication, and 1225 had engaged in self-care. Those seeking medical attention were associated with severe work function impairment compared with no work function impairment (adjusted OR = 2.84, 95% confidence interval: 1.82-4.45, p < .001). We observed a trend for the association between over-the-counter drug use with high levels of work function impairment (adjusted OR: 1.19 for low, 1.35 for moderate, 1.65 for severe). There was no apparent relationship between self-care and the degree of work functional impairment.

CONCLUSION

In workers with low back pain, severe work functional impairment may promote medical attention and over-the-counter medication use, but it would not encourage self-care, such as stretching or exercise. Therefore, workplaces need to provide special support to help them take care of themselves. Therefore, it is desirable to provide good support for self-care in the workplace.

Patient Information Leaflets for Lumbar Spine Surgery: A Missed Opportunity

BACKGROUND

High-quality patient information is recommended to help reduce procedure-related anxiety and encourage patients to become active participants in their recovery. The objective of this study was to analyze the quality of patient information leaflets (PILs) given to National Health Service (NHS) patients ahead of lumbar spine surgery.

METHODS

The DISCERN tool was used to evaluate the quality of PILs, sourced from NHS websites.

RESULTS

Thirty-two PILs on lumbar surgery were included. Two (6%) leaflets were considered poor, 13 (41%) were marked as fair, 14 (44%) were of good quality, and 3 (9%) were scored as excellent. The total mean score was 55 (30-74), which corresponds to good quality. The lowest scoring questions were sources of information (Q4), balanced/unbiased content (Q6), and explanation of no treatment (Q12).

CONCLUSIONS

There is considerable variation in the quality of PILs provided ahead of lumbar spine surgery. The scope for improvement is clear, and as the move toward patient-centered, evidence-based care continues, it is important that hospital resources provide recommendations based upon evidence of clinical effectiveness.

Exercise/physical activity and health outcomes: an overview of Cochrane systematic reviews

BACKGROUND

Sedentary lifestyle is a major risk factor for noncommunicable diseases such as cardiovascular diseases, cancer and diabetes. It has been estimated that approximately 3.2 million deaths each year are attributable to insufficient levels of physical activity. We evaluated the available evidence from Cochrane systematic reviews (CSRs) on the effectiveness of exercise/physical activity for various health outcomes.

METHODS

Overview and meta-analysis. The Cochrane Library was searched from 01.01.2000 to issue 1, 2019. No language restrictions were imposed. Only CSRs of randomised controlled trials (RCTs) were included. Both healthy individuals, those at risk of a disease, and medically compromised patients of any age and gender were eligible. We evaluated any type of exercise or physical activity interventions; against any types of controls; and measuring any type of health-related outcome measures. The AMSTAR-2 tool for assessing the methodological quality of the included studies was utilised.

RESULTS

Hundred and fifty CSRs met the inclusion criteria. There were 54 different conditions. Majority of CSRs were of high methodological quality. Hundred and thirty CSRs employed meta-analytic techniques and 20 did not. Limitations for studies were the most common reasons for downgrading the quality of the evidence. Based on 10 CSRs and 187 RCTs with 27,671 participants, there was a 13% reduction in mortality rates risk ratio (RR) 0.87 [95% confidence intervals (CI) 0.78 to 0.96]; I2 = 26.6%, [prediction interval (PI) 0.70, 1.07], median effect size (MES) = 0.93 [interquartile range (IQR) 0.81, 1.00]. Data from 15 CSRs and 408 RCTs with 32,984 participants showed a small improvement in quality of life (QOL) standardised mean difference (SMD) 0.18 [95% CI 0.08, 0.28]; I2 = 74.3%; PI -0.18, 0.53], MES = 0.20 [IQR 0.07, 0.39]. Subgroup analyses by the type of condition showed that the magnitude of effect size was the largest among patients with mental health conditions.

CONCLUSION

There is a plethora of CSRs evaluating the effectiveness of physical activity/exercise. The evidence suggests that physical activity/exercise reduces mortality rates and improves QOL with minimal or no safety concerns.

Are Opioids Needed to Treat Chronic Low Back Pain? A Review of Treatment Options and Analgesics in Development

The continued prevalence of chronic low back pain (CLBP) is a testament to our lack of understanding of the potential causes, leading to significant treatment challenges. CLBP is the leading cause of years lived with disability and the fifth leading cause of disability-adjusted life-years. No single non-pharmacologic, pharmacologic, or interventional therapy has proven effective as treatment for the majority of patients with CLBP. Although non-pharmacologic therapies are generally helpful, they are often ineffective as monotherapy and many patients lack adequate access to these treatments. Noninvasive treatment measures supported by evidence include physical and chiropractic therapy, yoga, acupuncture, and non-opioid and opioid pharmacologic therapy; data suggest a moderate benefit, at most, for any of these therapies. Until our understanding of the pathophysiology and treatment of CLBP advances, clinicians must continue to utilize rational multimodal treatment protocols. Recent Centers for Disease Control and Prevention guidelines for opioid prescribing recommend that opioids not be utilized as first-line therapy and to limit the doses when possible for fear of bothersome or dangerous adverse effects. In combination with the current opioid crisis, this has caused providers to minimize or eliminate opioid therapy when treating patients with chronic pain, leaving many patients suffering despite optimal nonopioid therapies. Therefore, there remains an unmet need for effective and tolerable opioid receptor agonists for the treatment of CLBP with improved safety properties over legacy opioids. There are several such agents in development, including opioids and other agents with novel mechanisms of action. This review critiques non-pharmacologic and pharmacologic treatment modalities for CLBP and examines the potential of novel opioids and other analgesics that may be a useful addition to the treatment options for patients with chronic pain.

Different weekly frequencies of Pilates did not accelerate pain improvement in patients with chronic low back pain

BACKGROUND

Recent evidence recommends Pilates for the treatment of chronic low back pain. However, it is still unknown if different weekly frequencies of Pilates can accelerate the improvement of symptoms in patients with chronic low back pain verified by a daily pain assessment.

OBJECTIVE

To analyze whether different weekly frequencies of Pilates can accelerate pain reduction by 30%, 50%, and 100% in patients with non-specific chronic low back pain and the necessary number of weeks to reach these improvements.

METHODS

Two hundred and twenty-two patients were randomized into three groups: Pilates group 1 received treatment once a week, Pilates group 2 received treatment twice a week, and Pilates group 3 received treatment three times a week. All groups received Pilates for six weeks. Pain intensity was measured daily before and after each intervention session using the Pain Numerical Rating Scale. The assessor was not blind.

RESULTS

The survival analysis showed that all Pilates groups had a pain reduction of 30%, 50%, and 100% at the same speed during treatment. There was no difference between the different weekly frequencies of Pilates for any of the comparisons (p>0.05). After the first week of treatment, 44.6% of the patients in Pilates group 3 showed complete pain improvement, followed by 37.8% of the patients in Pilates group 2 and 29.7% in Pilates group 1. After the last week, 71.6% (Pilates group 1), 77% (Pilates group 2), and 78.4% (Pilates group 3) of the patients reported complete improvement of symptoms.

CONCLUSION

Different weekly frequencies of Pilates did not accelerate pain improvement in patients with non-specific chronic low back pain. Registered in Clinical Trials Registry: NCT02241538 (https://clinicaltrials.gov/ct2/show/NCT02241538).

Examination of a Subgroup of Patients With Chronic Low Back Pain Likely to Benefit More From Pilates-Based Exercises Compared to an Educational Booklet

OBJECTIVE

To investigate whether 2 previously published classification approaches, the updated treatment-based classification system and a Pilates subgroup defined by a preliminary clinical prediction rule, could identify patients with chronic low back pain who would benefit more from Pilates exercises compared to an educational booklet.

DESIGN

Secondary analysis of a randomized controlled trial.

METHODS

Two hundred twenty-two patients received advice and were randomly allocated to a group that received an educational booklet with no additional treatment (n = 74) or a group that received Pilates-based exercise treatment (n = 148) 2 or 3 times a week. At baseline, using a treatment-based classification system, patients were classified as having a good prognosis (positive movement control) or a poor prognosis. Similarly, using the Pilates clinical prediction rule, patients were classified as having a good prognosis (positive) or a poor prognosis (negative). The analysis was conducted using linear regression models to analyze the interaction between subgroup characteristics and treatment effect size, with changes in pain and disability from baseline to 6 weeks after randomization as dependent variables.

RESULTS

None of the interaction terms for pain and disability were statistically significant. The treatment effect of Pilates versus an educational booklet was similar in all subgroups.

CONCLUSION

The treatment-based classification system and the Pilates clinical prediction rule did not differentiate subgroups of patients with chronic low back pain who were more or less likely to benefit more from Pilates compared to an educational booklet.

Physical therapies for postural abnormalities in people with cystic fibrosis

BACKGROUND

Cystic fibrosis (CF) is the most common life-threatening, inherited disease in white populations which causes several dysfunctions, including postural abnormalities. Physical therapy may help in some consequences of these postural abnormalities, such as pain, trunk deformity and quality of life.

OBJECTIVES

To determine the effects of a range of physical therapies for managing postural abnormalities in people with cystic fibrosis, specifically on quality of life, pain and trunk deformity.

SEARCH METHODS

We searched the Cochrane Cystic Fibrosis Trials Register, compiled from electronic database searches, hand-searched journals and conference abstract books. We also searched the reference lists of relevant articles and reviews. Additional searches were conducted on ClinicalTrials.gov and on the WHO International Clinical Trials Registry Platform for any planned, ongoing and unpublished studies. Date of the last search: 19 March 2020.

SELECTION CRITERIA

Randomised controlled trials examining any modality of physical therapy considered relevant for treating postural disorders compared with each other, no physical therapy, sham treatment or usual care in people with CF (of any age or disease severity).

DATA COLLECTION AND ANALYSIS

Two review authors independently selected eligible trials, assessed the risk of bias in each trial and extracted the data. We contacted trial authors to obtain missing or additional information. We assessed the quality of the evidence using the GRADE criteria.

MAIN RESULTS

Two trials, involving a total of 50 participants with CF and postural abnormalities, were included in this review. One was in people with stable disease (lasting three months) and one in hospital inpatients experiencing an exacerbation (20 days). Both trials compared manual therapy comprising mobilizations to the rib cage and thoracic spine, treatment of specific muscle dysfunction or tight muscle groups; and postural awareness and education versus medical usual care. The age of participants ranged from 17 years to 58 years. Both trials were conducted in the UK. The following outcomes were measured: change in quality of life, change in pain, change in trunk deformity and change in pulmonary function. Manual therapy may make little or no difference to the change in trunk deformity compared to usual care (low-quality evidence). No results could be analysed for quality of life (very low-quality evidence) and pain outcomes (very low-quality evidence) because of the high heterogeneity between trials. It is uncertain whether the intervention improves lung function: forced vital capacity (very low-quality evidence); forced expiratory volume in one second (very low-quality evidence); or Tiffeneau's index (ratio of forced expiratory volume at one second (FEV₁) and forced vital capacity (FVC)). Only one trial (15 participants) measured functional capacity, and the change in walked distance seemed to favour intervention over usual care, but with the possibility of no effect due to wide confidence intervals. The same trial also reported that six participants in the intervention group had positive comments about the intervention and no adverse events were mentioned.

AUTHORS' CONCLUSIONS

Due to methodological limitations in the included trials, and in addition to the very low to low quality of the current evidence, there is limited evidence about the benefits of physical therapies on postural abnormalities in people with CF. Therefore, further well-conducted trials with robust methodologies are required considering a prior inclusion criterion to identify the participants who have postural abnormalities.

Load monitoring on Pilates training: a study protocol for a randomized clinical trial

Background

Currently there are campaigns to raise the awareness of the need to practice physical exercise with several objectives, mainly as a preventive measure. The Pilates method is a form of therapeutic exercise for maintaining and improving health. However, despite being popular, there is still no scientific evidence on the standardization and progression of the method. Therefore, the purpose of this study was to develop a protocol to monitor the progression of daily Pilates loads between the basic, intermediate, and advanced levels, as well as to analyze the effects of the method on psychometric, cardiorespiratory, and autonomic measures.

Methods/design

In total, 54 healthy men underwent 36 sessions of Pilates mat work. Before each training session, cardiorespiratory measures, pain (visual analogue scale), and a psychometric questionnaire were collected. Heart rate (HR), subjective perception of effort (SPE), and RR intervals were measured during the sessions and used later in the analysis of the progression of training load by monitoring the internal training load and heart rate variability. At the end of the sessions, cardiorespiratory measures, the visual analogue scale, and the psychometric questionnaire were measured again. After 15 min of rest, the final HR measurement was made and the participants noted the effort on the SPE scale. The psychometric, cardiorespiratory, and autonomic measures were evaluated before and after each of the 36 training sessions.

Discussion

This is a parallel randomized clinical trial of standardized Pilates training, with the aim of estimating training loads and measuring the efficacy of Pilates through clinical, cardiorespiratory, and autonomic outcomes. The protocol can easily be reproduced and could be used to support professionals in prescribing the method.

RESTORE-Cognitive functional therapy with or without movement sensor biofeedback versus usual care for chronic, disabling low back pain: study protocol for a randomised controlled trial

INTRODUCTION

Low back pain (LBP) is the leading cause of disability globally and its costs exceed those of cancer and diabetes combined. Recent evidence suggests that individualised cognitive and movement rehabilitation combined with lifestyle advice (cognitive functional therapy (CFT)) may produce larger and more sustained effects than traditional approaches, and movement sensor biofeedback may enhance outcomes. Therefore, this three-arm randomised controlled trial (RCT) aims to compare the clinical effectiveness and economic efficiency of individualised CFT delivered with or without movement sensor biofeedback, with usual care for patients with chronic, disabling LBP.

METHODS AND ANALYSIS

Pragmatic, three-arm, randomised, parallel group, superiority RCT comparing usual care (n=164) with CFT (n=164) and CFT-plus-movement-sensor-biofeedback (n=164). Inclusion criteria include: adults with a current episode of LBP >3 months; sought primary care ≥6 weeks ago for this episode of LBP; average LBP intensity of ≥4 (0-10 scale); at least moderate pain-related interference with work or daily activities. The CFT-only and CFT-plus-movement-sensor-biofeedback participants will receive seven treatment sessions over 12 weeks plus a 'booster' session at 26 weeks. All participants will be assessed at baseline, 3, 6, 13, 26, 40 and 52 weeks. The primary outcome is pain-related physical activity limitation (Roland Morris Disability Questionnaire). Linear mixed models will be used to assess the effect of treatment on physical activity limitation across all time points, with the primary comparison being a formal test of adjusted mean differences between groups at 13 weeks. For the economic (cost-utility) analysis, the primary outcome of clinical effect will be quality-adjusted life years measured across the 12-month follow-up using the EuroQol EQ-5D-5L .

ETHICS AND DISSEMINATION

Approved by Curtin University Human Research Ethics Committee (HRE2018-0062, 6 Feb 2018). Study findings will be disseminated through publication in peer-reviewed journals and conference presentations.

Neuromuscular exercise reduces low back pain intensity and improves physical functioning in nursing duties among female healthcare workers; secondary analysis of a randomised controlled trial

Background

Low back pain (LBP) is common among healthcare workers, whose work is physically strenuous and thus demands certain levels of physical fitness and spinal control. Exercise is the most frequently recommended treatment for LBP. However, exercise interventions targeted at sub-acute or recurrent patients are scarce compared to those targeted at chronic LBP patients. Our objective was to examine the effects of 6 months of neuromuscular exercise on pain, lumbar movement control, fitness, and work-related factors at 6- and 12-months’ follow-up among female healthcare personnel with sub-acute or recurrent low back pain (LBP) and physically demanding work.

Methods

A total of 219 healthcare workers aged 30–55 years with non-specific LBP were originally allocated to four groups (exercise, counselling, combined exercise and counselling, control). The present study is a secondary analysis comparing exercisers (n = 110) vs non-exercisers (n = 109). Exercise was performed twice a week (60 min) in three progressive stages focusing on controlling the neutral spine posture. The primary outcome was intensity of LBP. Secondary outcomes included pain interfering with work, lumbar movement control, fitness components, and work-related measurements. Between-group differences were analysed with a generalised linear mixed model according to the intention-to-treat principle. Per-protocol analysis compared the more exercised to the less exercised and non-exercisers.

Results

The mean exercise attendance was 26.3 (SD 12.2) of targeted 48 sessions over 24 weeks, 53% exercising 1–2 times a week, with 80% (n = 176) and 72% (n = 157) participating in 6- and in 12-month follow-up measurements, respectively. The exercise intervention reduced pain (p = 0.047), and pain interfering with work (p = 0.046); improved lumbar movement control (p = 0.042), abdominal strength (p = 0.033) and physical functioning in heavy nursing duties (p = 0.007); but had no effect on other fitness and work-related measurements when compared to not exercising. High exercise compliance resulted in less pain and better lumbar movement control and walking test results.

Conclusion

Neuromuscular exercise was effective in reducing pain and improving lumbar movement control, abdominal strength, and physical functioning in nursing duties compared to not exercising.

Chronic nonspecific (musculoskeletal) low back pain. Guidelines of the Russian Society for the Study of Pain (RSSP)

Examination of a patient with chronic low back pain (LBP) is aimed at eliminating its specific cause and assessing the social and psychological factors of chronic pain. The diagnosis of chronic nonspecific (musculoskeletal) LBP is based on the exclusion of a specific cause of pain, discogenic radiculopathy, and lumbar stenosis. It is advisable to identify possible pain sources: pathology of intervertebral disc pathology, facet joints, and sacroiliac joint and myofascial syndrome.

An integrated multidisciplinary approach (a high level of evidence), including therapeutic exercises, physical activity optimization, psychological treatments (cognitive behavioral therapy), an educational program (back pain school for patients), and manual therapy, is effective in treating chronic musculoskeletal LBP. For pain relief, one may use nonsteroidal anti-inflammatory drugs in minimally effective doses and in a short cycle, muscle relaxants, and a capsaicin patch, and, if there is depressive disorder, antidepressants (a medium level of evidence). Radiofrequency denervation or therapeutic blockages with anesthetics and glucocorticoids (damage to the facet joints, sacroiliac joint), back massage, and acupuncture (a low level of evidence) may be used in some patients.

Therapeutic exercises and an educational program (the prevention of excessive loads and prolonged static and uncomfortable postures and the use of correct methods for lifting weights, etc.) are recommended for preventive purposes. 

Effectiveness of the Pilates method versus aerobic exercises in the treatment of older adults with chronic low back pain: a randomized controlled trial protocol

BACKGROUND

Chronic low back pain is potentially disabling for older adults, and exercise is considered the best treatment. The Pilates method and aerobic exercises have been proven to be effective in pain and function improvement in patients with low back pain, but evidence in the treatment of older adults with low back pain is scarce. Therefore, the objective of this study is to investigate the effectiveness of the Pilates method compared to aerobic exercises in the treatment of older adults with chronic nonspecific low back pain.

METHODS

This is a randomized controlled trial with blinded assessor, to be held in a physical therapy clinic in Sao Paulo, Brazil. Seventy four patients aged 65 to 85 years with chronic nonspecific pain will be randomized into Pilates Group (n = 37) with exercises based on the Pilates method and Aerobic Group (n = 37) with treadmill aerobic exercise. The primary outcomes will be pain intensity and general disability, assessed eight weeks after randomization. The secondary outcomes will be: pain intensity and general disability, assessed six months after randomization; and global perceived improvement, specific disability, dynamic balance, muscle strength (gluteus maximus, gluteus medius, and lateral hip rotators), and pressure pain threshold, assessed eight weeks and six months after randomization. Therapists and patients will not be blinded.

DISCUSSION

This study has the potential to reduce pain and, consequently, improve balance and function of older adults with chronic low back pain with both therapies. However, Pilates may be more effective because the exercises are more targeted to the trunk stabilization muscles. The results of this study may provide valuable information on the effects of Pilates and aerobic exercise in older adults with chronic low back pain and contribute to a better selection of the treatment program according to the patient preference.

Overall confidence in the results of systematic reviews on exercise therapy for chronic low back pain: a cross-sectional analysis using the Assessing the Methodological Quality of Systematic Reviews (AMSTAR) 2 tool

OBJECTIVE

To evaluate the overall confidence in the results of systematic reviews of exercise therapy for chronic non-specific low back pain using the AMSTAR 2 tool.

METHODS

PubMed, Embase, Cochrane Database of Systematic Reviews, PEDro and CINAHL was searched up to February 2017. Two independent reviewers selected systematic reviews of randomized controlled trials that investigated exercise therapy in patients with low back pain. AMSTAR 2 assessment was performed by pairs of reviewers, and the overall confidence in the results of the systematic reviews were rated as 'High', 'Moderate', 'Low' and 'Critically low'. Descriptive analysis was used to summarize the characteristics of included systematic reviews. The percentage of systematic reviews achieving each item from the AMSTAR 2 and the overall confidence in the results were tabulated.

RESULTS

The search identified 38 systematic reviews. Most of the reviews included a median of 10 clinical trials and total sample size of 813 participants per review. Five of 38 (13%) reviews were Cochrane reviews, and 8 (21%) systematic reviews had a protocol published or registered prospectively. The overall confidence in the results of 28 reviews (74%) was rated as 'Critically low', 6 (16%) as 'Low', 1 (2%) as Moderate, while 3 of 38 reviews (8%) were rated as 'High'.

CONCLUSION

The results demonstrate very low confidence in the results of most systematic reviews of exercise in chronic non-specific low back pain. Clinicians are more likely to deliver the most efficacious interventions to patients by critically appraising systematic reviews using AMSTAR 2 before making their decisions.

Effectiveness and cost-effectiveness of the modified Pilates method versus aerobic exercise in the treatment of patients with fibromyalgia: protocol for a randomized controlled trial

Background

Fibromyalgia is characterized by chronic generalized pain, fatigue, sleep disorders and other symptoms. Physical exercise is recommended as the first choice of non-pharmacological therapy. Thus, the aim of this study is to evaluate the effectiveness and cost-effectiveness of modified Pilates exercises compared to aerobic exercises in the treatment of patients with fibromyalgia.

Methods

In this randomized controlled trial with blinded assessor, 98 patients who meet the fibromyalgia classification criteria of the American College of Rheumatology 2010, aged between 20 and 75 years, and with pain intensity greater than or equal to 3 points in the Pain Numerical Rating Scale, will be randomly divided into Aerobic Group (aerobic exercises on treadmills or stationary bikes) and Pilates Group (modified Pilates exercises), and treated twice a week for eight weeks on the Center for Excellence in Clinical Research in Physical Therapy at Universidade Cidade de São Paulo, Brazil. The following outcomes will be evaluated by a blinded assessor at baseline, eight weeks, six months, and 12 months after randomization: impact of fibromyalgia assessed by the Fibromyalgia Impact Questionnaire, pain intensity by the Pain Numerical Rating Scale, kinesiophobia by the Tampa Scale of Kinesiophobia, specific disability by the Patient-Specific Functional Scale, functional capacity by the 6-min Walk Test, quality of sleep by the Pittsburgh Sleep Quality Index, and health-related quality of life by EQ-5D-3L and SF-6D questionnaires.

Discussion

It is expected that the Pilates exercises will be more effective than aerobic exercises in improving clinical outcomes and that this improvement will be maintained over the medium to long term. This study aims to clarify whether the Pilates method can be incorporated into the clinical practice of physical therapists treating patients with fibromyalgia. The study will also provide information on which exercise will be most cost-effective, information that can be used by insurers and public health systems.

Trial registration

This study was prospectively registered at the Clinical Trials Registry (NCT03050606) in February 2017.

Application of Pilates-based exercises in the treatment of chronic non-specific low back pain: state of the art

According to the current recommendations on the management of chronic non-specific low back pain (CNLBP), the intervention in this group of patients should include a programme of exercises. Pilates is a system of exercises widely used in patients with low back pain. The practices based on this method have promoted the restoration of the function of muscles involved in lumbopelvic stabilisation, that is, transversus abdominis, multifidus, diaphragm and pelvic floor muscles. During each exercise, specific principles of this method should be followed to restore or sustain the motor control of the lumbar spine and proper body posture. The aim of this study is to present the current state of knowledge concerning the application of Pilates method in the management of CNLBP as well as to define factors (eg, duration, frequency, exercises performed on a mat or specific equipment) influencing the effectiveness of Pilates in these individuals.

Exercise-induced hypoalgesia: A meta-analysis of exercise dosing for the treatment of chronic pain

OBJECTIVE

Increasing evidence purports exercise as a first-line therapeutic for the treatment of nearly all forms of chronic pain. However, knowledge of efficacious dosing respective to treatment modality and pain condition is virtually absent in the literature. The purpose of this analysis was to calculate the extent to which exercise treatment shows dose-dependent effects similar to what is seen with pharmacological treatments.

METHODS

A recently published comprehensive review of exercise and physical activity for chronic pain in adults was identified in May 2017. This report reviewed different physical activity and exercise interventions and their effectiveness in reducing pain severity and found overall modest effects of exercise in the treatment of pain. We analyzed this existing data set, focusing specifically on the dose of exercise intervention in these studies. We re-analyzed data from 75 studies looking at benefits of time of exercising per week, frequency of exercise per week, duration of intervention (in weeks), and estimated intensity of exercise.

RESULTS

Analysis revealed a significant positive correlation with exercise duration and analgesic effect on neck pain. Multiple linear regression modeling of these data predicted that increasing the frequency of exercise sessions per week is most likely to have a positive effect on chronic pain patients.

DISCUSSION

Modest effects were observed with one significant correlation between duration and pain effect for neck pain. Overall, these results provide insufficient evidence to conclude the presence of a strong dose effect of exercise in pain, but our modeling data provide tes predictions that can be used to design future studies to explicitly test the question of dose in specific patient populations.

GLA:D® Back group-based patient education integrated with exercises to support self-management of back pain - development, theories and scientific evidence

BACKGROUND

Clinical guidelines recommend that people with back pain be given information and education about their back pain, advice to remain active and at work, and exercises to improve mobility and physical activity. Guidelines, however, rarely describe how this is best delivered. The aim of this paper is to present the development, theories, and underlying evidence for 'GLA:D Back' - a group education and exercise program that translates guideline recommendations into a clinician-delivered program for the promotion of self-management in people with persistent/recurrent back pain.

METHODS

GLA:D Back, which included a rationale and objectives for the program, theory and evidence for the interventions, and program materials, was developed using an iterative process. The content of patient education and exercise programs tested in randomised trials was extracted and a multidisciplinary team of expert researchers and clinicians prioritised common elements hypothesised to improve back pain beliefs and management skills. The program was tested on eight people with persistent back pain in a university clinic and 152 patients from nine primary care physiotherapy and chiropractic clinics. Following feedback from the clinicians and patients involved, the working version of the program was created.

RESULTS

Educational components included pain mechanisms, pain modulation, active coping strategies, imaging, physical activity, and exercise that emphasised a balance between the sum of demands and the individual's capacity. These were operationalised in PowerPoint presentations with supporting text to aid clinicians in delivering two one-hour patient education lectures. The exercise program included 16 supervised one-hour sessions over 8 weeks, each comprising a warm-up section and eight types of exercises for general flexibility and strengthening of six different muscle groups at four levels of difficulty. The aims of the exercises were to improve overall back fitness and, at the same time, encourage patients to explore variations in movement by incorporating education content into the exercise sessions.

CONCLUSION

From current best evidence about prognostic factors in back pain and effective treatments for back pain, research and clinical experts developed a ready-to-use structured program - GLA:D® Back - to support self-management for people with persistent/recurrent back pain.

Predictive factors for progression through the difficulty levels of Pilates exercises in patients with low back pain: a secondary analysis of a randomized controlled trial

BACKGROUND

The progression through the difficulty levels of Pilates exercises is a subjective criterion, that depends on the therapist's experience and ability to identify the best moment to progress to the next level.

OBJECTIVE

To identify the factors that interfere in the progression through the difficulty levels of the Pilates exercises in patients with chronic nonspecific low back pain.

METHODS

Data from 139 patients with chronic nonspecific low back pain from a randomized controlled trial were used for statistical analysis using binary logistic regression. The dependent variable was the progression through the difficulty levels, and the independent variables were age, gender, educational level, low back pain duration, pain intensity, general disability, kinesiophobia, previous physical activity, and number of absences.

RESULTS

The factors that interfered in the progression through the difficulty levels were previous physical inactivity (odds ratio [OR]=5.14, 95% confidence interval [CI]: 1.53-17.31), low educational level (OR=2.62, 95% CI: 1.12-6.10), more advanced age (OR=0.95, 95% CI: 0.92-0.98) and more absences (OR=0.63, 95% CI: 0.50-0.79). These variables explain 41% of the non-progression through the difficulty level of the exercises.

CONCLUSION

Physical inactivity, low educational level, more advanced age and greater number of absences can be interfering factors in the progression through the difficulty levels of the Pilates exercises in patients with chronic nonspecific low back pain.

Scoping review of systematic reviews of complementary medicine for musculoskeletal and mental health conditions

OBJECTIVE

To identify potentially effective complementary approaches for musculoskeletal (MSK)-mental health (MH) comorbidity, by synthesising evidence on effectiveness, cost-effectiveness and safety from systematic reviews (SRs).

DESIGN

Scoping review of SRs.

METHODS

We searched literature databases, registries and reference lists, and contacted key authors and professional organisations to identify SRs of randomised controlled trials for complementary medicine for MSK or MH. Inclusion criteria were: published after 2004, studying adults, in English and scoring >50% on Assessing the Methodological Quality of Systematic Reviews (AMSTAR); quality appraisal checklist). SRs were synthesised to identify research priorities, based on moderate/good quality evidence, sample size and indication of cost-effectiveness and safety.

RESULTS

We included 84 MSK SRs and 27 MH SRs. Only one focused on MSK-MH comorbidity. Meditative approaches and yoga may improve MH outcomes in MSK populations. Yoga and tai chi had moderate/good evidence for MSK and MH conditions. SRs reported moderate/good quality evidence (any comparator) in a moderate/large population for: low back pain (LBP) (yoga, acupuncture, spinal manipulation/mobilisation, osteopathy), osteoarthritis (OA) (acupuncture, tai chi), neck pain (acupuncture, manipulation/manual therapy), myofascial trigger point pain (acupuncture), depression (mindfulness-based stress reduction (MBSR), meditation, tai chi, relaxation), anxiety (meditation/MBSR, moving meditation, yoga), sleep disorders (meditative/mind-body movement) and stress/distress (mindfulness). The majority of these complementary approaches had some evidence of safety-only three had evidence of harm. There was some evidence of cost-effectiveness for spinal manipulation/mobilisation and acupuncture for LBP, and manual therapy/manipulation for neck pain, but few SRs reviewed cost-effectiveness and many found no data.

CONCLUSIONS

Only one SR studied MSK-MH comorbidity. Research priorities for complementary medicine for both MSK and MH (LBP, OA, depression, anxiety and sleep problems) are yoga, mindfulness and tai chi. Despite the large number of SRs and the prevalence of comorbidity, more high-quality, large randomised controlled trials in comorbid populations are needed.

Which strength and balance activities are safe and efficacious for individuals with specific challenges (osteoporosis, vertebral fractures, frailty, dementia)?: A Narrative review

Physical activity guidelines advocate the inclusion of strength and balance activities, twice a week, for adults and older adults, but with caveat that in some individuals there will be certain movements and activities that could lead to adverse events. This scoping review summarizes the evidence about how safe and efficacious these activities are in older adults with specific challenges that might make them more prone to injury (e.g. having recently fractured or at risk of fracture (osteoporosis) or those who are frail or who have cognitive impairment). The review identified that for prevention of falls in people with a falls history and/or frailer older adults, structured exercise programmes that incorporate progressive resistance training (PRT) with increasing balance challenges over time are safe and effective if performed regularly, with supervision and support, over at least 6 months. Some minor adverse effects mainly transient musculoskeletal pain) have been reported. For those with a higher risk of falls and fractures (very poor balance, vertebral fractures), supervised structured exercise programmes are most appropriate. People with diagnosed osteoporosis should be as active as possible and only avoid activities with a high risk of falls if they are naïve to those activities. For those in transition to frailty who have poor strength and balance, exercises that are known to help maintain strength and balance (such as Tai Chi) are effective in preventing a decline in falls risk. For the very frail older adult, supervised structured exercise that has PRT, balance training and some endurance work, supervised and progressed by a trained person are advocated.

Failure to define low back pain as a disease or an episode renders research on causality unsuitable: results of a systematic review

Background

Causative factors may be different for the very first onset of symptoms of the ‘disease’ of low back pain (LBP) than for ensuing episodes that occur after a pain-free period. This differentiation hinges on a life-time absence of low back pain at first onset and short-term absence for further episodes. In this systematic review, we explored whether researchers make these distinctions when investigating the causality of LBP.

Methods

A literature search of PUBMED, CINAHL, and SCOPUS databases was performed from January 2010 until September 2016 using the search terms ‘low back pain’ or ‘back pain’ and ‘risk factor’ or ‘caus*’ or ‘predict*’ or ‘onset’ or ‘first-time’ or ‘inception’ or ‘incidence’. Two reviewers extracted information on study design, types of episodes of back pain to distinguish the disease of LBP and recurring episodes, and also to determine the definitions of disease- or pain-free periods.

Results

Thirty-three articles purporting to study causes of LBP were included. Upon scrutiny, 31 of the 33 articles were unclear as to what type of causality they were studying, that of the ‘disease’ or the episode, or a mere association with LBP. Only 9 studies used a prospective study design. Five studies appeared to investigate the onset of the disease of LBP, however, only one study truly captured the first incidence of LBP, which was the result of sports injury. Six appeared to study episodes but only one clearly related to the concept of episodes. Therefore, among those 11 studies, nine included both first-time LBP and episodes of LBP. Consequently, 22 studies related to the prevalence of LBP, as they probably included a mixture of first-time, recurring and ongoing episodes without distinction.

Conclusion

Recent literature concerning the causality of LBP does not differentiate between the ‘disease’ of LBP and its recurring episodes mainly due to a lack of a clear definition of absence of LBP at baseline. Therefore, current research is not capable of providing a valid answer on this topic.

Physical activity and exercise for chronic pain in adults: an overview of Cochrane Reviews

BACKGROUND

Chronic pain is defined as pain lasting beyond normal tissue healing time, generally taken to be 12 weeks. It contributes to disability, anxiety, depression, sleep disturbances, poor quality of life, and healthcare costs. Chronic pain has a weighted mean prevalence in adults of 20%.For many years, the treatment choice for chronic pain included recommendations for rest and inactivity. However, exercise may have specific benefits in reducing the severity of chronic pain, as well as more general benefits associated with improved overall physical and mental health, and physical functioning.Physical activity and exercise programmes are increasingly being promoted and offered in various healthcare systems, and for a variety of chronic pain conditions. It is therefore important at this stage to establish the efficacy and safety of these programmes, and furthermore to address the critical factors that determine their success or failure.

OBJECTIVES

To provide an overview of Cochrane Reviews of adults with chronic pain to determine (1) the effectiveness of different physical activity and exercise interventions in reducing pain severity and its impact on function, quality of life, and healthcare use; and (2) the evidence for any adverse effects or harm associated with physical activity and exercise interventions.

METHODS

We searched theCochrane Database of Systematic Reviews (CDSR) on the Cochrane Library (CDSR 2016, Issue 1) for systematic reviews of randomised controlled trials (RCTs), after which we tracked any included reviews for updates, and tracked protocols in case of full review publication until an arbitrary cut-off date of 21 March 2016 (CDSR 2016, Issue 3). We assessed the methodological quality of the reviews using the AMSTAR tool, and also planned to analyse data for each painful condition based on quality of the evidence.We extracted data for (1) self-reported pain severity, (2) physical function (objectively or subjectively measured), (3) psychological function, (4) quality of life, (5) adherence to the prescribed intervention, (6) healthcare use/attendance, (7) adverse events, and (8) death.Due to the limited data available, we were unable to directly compare and analyse interventions, and have instead reported the evidence qualitatively.

MAIN RESULTS

We included 21 reviews with 381 included studies and 37,143 participants. Of these, 264 studies (19,642 participants) examined exercise versus no exercise/minimal intervention in adults with chronic pain and were used in the qualitative analysis.Pain conditions included rheumatoid arthritis, osteoarthritis, fibromyalgia, low back pain, intermittent claudication, dysmenorrhoea, mechanical neck disorder, spinal cord injury, postpolio syndrome, and patellofemoral pain. None of the reviews assessed 'chronic pain' or 'chronic widespread pain' as a general term or specific condition. Interventions included aerobic, strength, flexibility, range of motion, and core or balance training programmes, as well as yoga, Pilates, and tai chi.Reviews were well performed and reported (based on AMSTAR), and included studies had acceptable risk of bias (with inadequate reporting of attrition and reporting biases). However the quality of evidence was low due to participant numbers (most included studies had fewer than 50 participants in total), length of intervention and follow-up (rarely assessed beyond three to six months). We pooled the results from relevant reviews where appropriate, though results should be interpreted with caution due to the low quality evidence. Pain severity: several reviews noted favourable results from exercise: only three reviews that reported pain severity found no statistically significant changes in usual or mean pain from any intervention. However, results were inconsistent across interventions and follow-up, as exercise did not consistently bring about a change (positive or negative) in self-reported pain scores at any single point. Physical function: was the most commonly reported outcome measure. Physical function was significantly improved as a result of the intervention in 14 reviews, though even these statistically significant results had only small-to-moderate effect sizes (only one review reported large effect sizes). Psychological function and quality of life: had variable results: results were either favourable to exercise (generally small and moderate effect size, with two reviews reporting significant, large effect sizes for quality of life), or showed no difference between groups. There were no negative effects. Adherence to the prescribed intervention: could not be assessed in any review. However, risk of withdrawal/dropout was slightly higher in the exercising group (82.8/1000 participants versus 81/1000 participants), though the group difference was non-significant. Healthcare use/attendance: was not reported in any review. Adverse events, potential harm, and death: only 25% of included studies (across 18 reviews) actively reported adverse events. Based on the available evidence, most adverse events were increased soreness or muscle pain, which reportedly subsided after a few weeks of the intervention. Only one review reported death separately to other adverse events: the intervention was protective against death (based on the available evidence), though did not reach statistical significance.

AUTHORS' CONCLUSIONS

The quality of the evidence examining physical activity and exercise for chronic pain is low. This is largely due to small sample sizes and potentially underpowered studies. A number of studies had adequately long interventions, but planned follow-up was limited to less than one year in all but six reviews.There were some favourable effects in reduction in pain severity and improved physical function, though these were mostly of small-to-moderate effect, and were not consistent across the reviews. There were variable effects for psychological function and quality of life.The available evidence suggests physical activity and exercise is an intervention with few adverse events that may improve pain severity and physical function, and consequent quality of life. However, further research is required and should focus on increasing participant numbers, including participants with a broader spectrum of pain severity, and lengthening both the intervention itself, and the follow-up period.

Contemporary biopsychosocial exercise prescription for chronic low back pain: questioning core stability programs and considering context

This commentary explores the importance of considering the biopsychosocial model and contextual factors when prescribing exercise. Diverse exercise programs for patients with chronic low back pain (CLBP) produce similar outcomes, without one specific exercise protocol demonstrating clear superiority. One clear barrier to positive outcomes is poor exercise adherence. We suggest that there are certain common contextual factors present in all exercise prescription scenarios that may impact adherence and health-related outcomes. While challenging common core stability exercise prescription, we present an argument for enhancing and intentionally shaping the following contextual factors: the therapeutic alliance, patient education, expectations and attributions of therapeutic success or failure, and mastery or cognitive control over a problem. Overall, this commentary argues that to improve exercise adherence and outcomes in the CLBP population, the context in which exercise is delivered and the meaning patients embody need to be considered and shaped by clinicians.

Non-specific low back pain

Non-specific low back pain affects people of all ages and is a leading contributor to disease burden worldwide. Management guidelines endorse triage to identify the rare cases of low back pain that are caused by medically serious pathology, and so require diagnostic work-up or specialist referral, or both. Because non-specific low back pain does not have a known pathoanatomical cause, treatment focuses on reducing pain and its consequences. Management consists of education and reassurance, analgesic medicines, non-pharmacological therapies, and timely review. The clinical course of low back pain is often favourable, thus many patients require little if any formal medical care. Two treatment strategies are currently used, a stepped approach beginning with more simple care that is progressed if the patient does not respond, and the use of simple risk prediction methods to individualise the amount and type of care provided. The overuse of imaging, opioids, and surgery remains a widespread problem.
