A multicenter feasibility randomized controlled trial using a virtual reality application of pain neuroscience education for adults with chronic low back pain

BACKGROUND

Chronic low back pain (CLBP) is a highly prevalent condition among adults and is correlated to high levels of pain, high disability, and lower quality of life. Pain neuroscience education (PNE) helps to explain the pain experience and can affect psychosocial factors, such as fear of movement, anxiety, socioeconomic status, work life satisfaction, etc. More recently, virtual reality (VR) programs have emerged allowing for immersive PNE experiences.

OBJECTIVE

The purpose of this randomized clinical trial is to determine the feasibility of using a VR application for the delivery of immersive PNE (VR-PNE) and other activity training for patients with CLBP presenting to outpatient physical therapy (PT) clinics.

METHODS

A two-arm, parallel group, randomized controlled feasibility trial of patients was conducted at 12 outpatient PT clinics from March 9, 2022, through September 9, 2022. The intervention group received PT as usual and VR-PNE while the control group received PT as usual. Between group feasibility, acceptability outcomes and other patient-reported outcomes were assessed at six weeks.

RESULTS

A total of 595 individuals were evaluated for low back pain during the recruitment period. Seventy individuals were eligible and met definition for CLBP, 52 enrolled and 32 completed the trial. Participant adherence was 63.6% for VR-PNE and 63.2% for PT as usual. Participants found VR-PNE acceptable and reported satisfaction scores (0-100) of 87.37 ± 11.05 compared to 81.17 ± 23.72 in the PT as usual group. There were no significant differences between groups for the BBQ, BRS, FABQ-PA, FABQ-W, GROC, NPRS, NPQ, PCS, and PSEQ at 6 weeks.

CONCLUSION

The results of the trial suggest that VR-PNE may be acceptable and feasible for patients with CLBP. Study procedures and PT delivery modifications should be considered for the next iteration of this study to improve follow-up assessment rates.

Cognitive Functional Therapy compared with usual physiotherapy care in people with persistent low back pain: a mixed methods feasibility randomised controlled trial in the United Kingdom National Health Service

OBJECTIVES

To determine the feasibility of completing a definitive randomised controlled trial (RCT), evaluating the clinical and cost-effectiveness of Cognitive Functional Therapy (CFT) in comparison to usual physiotherapy care (UPC), for people with persistent low back pain (LBP).

DESIGN AND SETTING

A two-arm parallel feasibility RCT completed in a United Kingdom (UK) Secondary Care National Health Service (NHS) physiotherapy service.

PARTICIPANTS

Sixty adult participants who reported LBP lasting for more than three months, that was not attributable to a serious (e.g. cancer) or specific (e.g. radiculopathy) underlying cause, were invited to participate. Participants were allocated at random to receive CFT or UPC.

INTERVENTIONS

Cognitive Functional Therapy and Usual Physiotherapy Care for persistent LBP.

MAIN OUTCOME MEASURES

The primary outcome was the feasibility of completing a definitive RCT, defined by recruitment of at least 5 participants per month, delivery of CFT per protocol and securing relevant and acceptable outcome measures. Data concerning study processes, resources, management and participant reported outcome measures were collected at baseline, 3, 6 and 12-month follow-up.

RESULTS

Sixty participants (n = 30 CFT and n = 30 UPC) were recruited with 80% (n = 48), 72% (n = 43) and 53% (n = 32) retained at 3, 6 and 12-month follow-up respectively. NHS physiotherapists were trained to competence and delivered CFT with fidelity. CFT was tolerated by participants with no adverse events. Relevant and clinically important outcome data were collected at all time points (0.4%, 3%, 1% and 0.8% of data was missing from the returned outcome measure booklets at baseline and 3, 6 and 12-month follow-up respectively). The Roland-Morris disability questionnaire was considered the most suitable primary outcome measure with a proposed sample size of 540 participants for a definitive cluster RCT.

CONCLUSION

It is feasible to conduct a randomised study of CFT in comparison to UPC for NHS patients. A future study should incorporate an internal pilot to address aspects of feasibility further, including participant retention strategies.

Physical therapy for acute and sub-acute low back pain: A systematic review and expert consensus

OBJECTIVE

To review the effectiveness of different physical therapies for acute and sub-acute low back pain supported by evidence, and create clinical recommendations and expert consensus for physiotherapists on clinical prescriptions.

DATA SOURCES

A systematic search was conducted in PubMed and the Cochrane Library for studies published within the previous 15 years.

REVIEW METHODS

Systematic review and meta-analysis, randomized controlled trials assessing patients with acute and sub-acute low back pain were included. Two reviewers independently screened relevant studies using the same inclusion criteria. The Physiotherapy Evidence Database and the Assessment of Multiple Systematic Reviews tool were used to grade the quality assessment of randomized controlled trials and systematic reviews, respectively. The final recommendation grades were based on the consensus discussion results of the Delphi of 22 international experts.

RESULTS

Twenty-one systematic reviews and 21 randomized controlled trials were included. Spinal manipulative therapy and low-level laser therapy are recommended for acute low back pain. Core stability exercise/motor control, spinal manipulative therapy, and massage can be used to treat sub-acute low back pain.

CONCLUSIONS

The consensus statements provided medical staff with appliable recommendations of physical therapy for acute and sub-acute low back pain. This consensus statement will require regular updates after 5-10 years.

'Look up from the waiting list and see the bigger picture': a qualitative analysis of clinical specialist physiotherapist perspectives on low back pain care in Ireland

INTRODUCTION

Healthcare systems are struggling to deliver high-quality low back pain (LBP) care. In 2012 specialist physiotherapist-led musculoskeletal (MSK) triage services were introduced in Irish hospitals to expedite patient care and alleviate pressure on elective orthopaedic/ rheumatology consultant clinics. Specialist physiotherapists have expertise to inform health service improvement and reform, but their perspectives of LBP healthcare delivery have received scant attention.

OBJECTIVES

To explore specialist physiotherapists' perspectives on LBP care in Ireland, the barriers and facilitators to quality LBP care and the development of MSK interface services in primary care settings.

DESIGN

Cross-sectional observational study using an anonymous electronic survey with thematic framework analysis of response data from open-ended questions.

PARTICIPANTS

Thirty-four clinical specialist physiotherapists in Irish MSK triage services.

RESULTS

Thematic analysis resulted in six overarching themes, grouped into two categories. One category pertained to LBP healthcare in Ireland with the following three themes: 1) Inadequate health services for patients with LBP; 2) Need for defined LBP clinical pathways; 3) Need for a multisectoral approach to spine health. Themes in the second category, pertaining to the development of community-based MSK interface services, were: 4) Concern regarding isolation from secondary care services; 5) Unrealistic expectations of MSK triage; 6) Improved communication and collaboration with primary care services.

CONCLUSION

Specialist physiotherapists have concerns regarding LBP health services and persistence of a biomedical, secondary care-led approach. They advocate for investment in primary care multi-disciplinary teams, enhanced integration across primary and secondary care, development of a national clinical pathway and a multisectoral approach.

Neuromuscular Control and Resistance Training for People With Chronic Low Back Pain: A Randomized Controlled Trial

OBJECTIVE: To determine if adding lumbar neuromuscular control retraining exercises to a 12-week program of strengthening exercises had greater effect for improving disability than 12 weeks of strengthening exercises alone in people with chronic low back pain (LBP). DESIGN: Single-center, participant- and assessor-blinded, comparative effectiveness randomized controlled trial. METHODS: Sixty-nine participants (31 females; 29 males; mean age: 46.5 years) with nonspecific chronic LBP were recruited for a 12-week program involving lumbar extension neuromuscular retraining in addition to resistance exercises (intervention) or 12 weeks of resistance exercises alone (control). The primary outcome measure was the Oswestry Disability Index. Secondary outcome measures included the Numeric Rating Scale, Tampa Scale for Kinesiophobia, Pain Self-Efficacy Questionnaire, and the International Physical Activity Questionnaire. Outcomes were measured at baseline, 6 weeks, and 12 weeks. RESULTS: Forty-three participants (22 control, 21 intervention) completed all outcome measures at 6 and 12 weeks. Fourteen participants were lost to follow-up, and 12 participants discontinued due to COVID-19 restrictions. Both groups demonstrated clinically important changes in disability, pain intensity, and kinesiophobia. The difference between groups with respect to disability was imprecise and not clinically meaningful (mean difference, -4.4; 95% CI: -10.2, 1.4) at 12 weeks. Differences in secondary outcomes at 6 or 12 weeks were also small with wide confidence intervals. CONCLUSIONS: Adding lumbar neuromuscular control retraining to a series of resistance exercises offered no additional benefit over resistance exercises alone over a 12-week period.

How do non-specific back pain patients think about their adherence to physiotherapy, and what strategies do physiotherapists use to facilitate adherence? A focus group interview study

BACKGROUND

Long-term effectiveness of physiotherapy (PT) for low back pain (LBP) depends on the adherence of patients. Objectives: (1) Identify aspects associated with the adherence of patients with LBP to physiotherapy, and (2) identify factors to facilitate adherence of patients with LBP to PT.

METHOD

Focus group interviews were conducted with 10 patients with LBP (n = 10, 5 women) and 11 physiotherapists (5 women) from Germany and Switzerland, treating patients with LBP. Data analysis was based on structured content analysis. Deductive and inductive categories were identified and coded.

RESULTS

Patients with LBP requested more and effective home programs, long-term rehabilitation management, and individualized therapy to achieve a higher level of adherence. Physiotherapists requested more time for patient education. Communication, quality of the therapist-patient relationship, and individualized therapy were identified as essential factors by both representatives.

CONCLUSION

Patients and physiotherapists identified aspects contributing to adherence. These may guide the development of multidimensional measurement tools for adherence. In addition, this information can be used to develop PT approaches to facilitate the level of adherence.

[Research Progress in Data Acquisition and Intelligent Sensing Methods for Lumbar Electromyographic Signals]

Population aging trend is taking place in our country, and low back pain is a symptom of neuromuscular diseases of concern in the elderly. Accurately analyzing the disease of low back pain is important for both timely intervention and rehabilitation of patients. As a kind of bioelectrical signal, the acquisition and analysis of lumbar electromyography (EMG) signal is an important direction for the study of low back pain. The study reviews the acquisition of lumbar EMG by different types of sensors, introduces the signal characteristics of needle electrodes, surface electromyography electrodes and array electrodes, describes the use of signal algorithms, points out that wireless sensors and the use of deep learning algorithms are the direction of development, and puts forward prospects for its further development.

Rehabilitation of sick-listed LBP patients in occupational health with collaboration of the workplace

The aim was to evaluate if rehabilitation procedures including occupational health (OH) and workplace participation increase return to work (RTW) rates among patients with subacute and chronic low back pain (LBP). A systematic review of randomized controlled trials was conducted using the PubMed and Cochrane databases. Main outcomes were RTW and days of sick leave. Interventions needed to be multidisciplinary including both OH and active workplace involvement in rehabilitation. Out of 1073 potentially eligible references, 8 met the inclusion criteria. Three studies had OH and 5 case managers involved in rehabilitation. Rehabilitation involving both OH and workplace improved RTW and decreased the number of sick leave days among LBP patients. Having case managers involved had no effect in RTW. In order to improve RTW, workplace visits and work ability meetings (WAMs) between OH and workplace are essential components in the rehabilitation process among patients with chronic LBP. Based on the study results, the authors suggest utilizing these co-operative interventions with workplaces in OH. High quality research investigating only the effect of WAMs in OH setting is needed in future. Int J Occup Med Environ Health. 2024;37(1):3-17.

The effectiveness of telerehabilitation-based exercise combined with pain neuroscience education for patients with facet joint arthrosis: A randomized controlled study

OBJECTIVES

This study aimed to investigate the short-term effectiveness of exercise combined with PNE and exercise alone via telerehabilitation for patients with low back pain (LBP) caused by facet joint arthrosis (FJA).

METHODS

This is a prospective, single-blind, randomized-controlled clinical trial. Forty-five patients with LBP caused by FJA were randomly allocated into three groups. The exercise (n = 15) and the exercise with PNE (n = 15) groups were provided interventions twice a week for six weeks via telerehabilitation. The control group (n = 15) was placed on the waiting list. The primary outcome measures were the numeric pain-rating scale (NPRS) at rest and with activity, The Oswestry disability index (ODI), the pain beliefs questionnaire (PBQ), and secondary outcome measures were short form-12v2 (SF-12v2) and the global rating of change score (GROC).

RESULTS

The groups (52.00 ± 4.86, 46.7% female) were similar at baseline except for gender (p = 0.029). There was a significant group-by-time interaction for NPRS-rest (F = 4.276, p = 0.021), NPRS-activity (F = 12.327, p = 0.0001), the ODI (F = 23.122, p = 0.0001) and organic pain belief (F = 39.708, p = 0.0001). Further comparison with ANOVA showed that the exercise with PNE group showed better improvement in only organic pain belief (p = 0.0001). All groups reported improvements according to GROC, but it was higher in the intervention groups (p = 0.001).

CONCLUSION

The patients who received exercise combined with PNE and exercise alone significantly improved pain intensity, disability and organic pain beliefs via telerehabilitation for patients with LBP caused by FJA compared to the control group. The PNE in addition to exercise may exhibit greater benefit in improving organic pain beliefs in short term.

SIGNIFICANCE

This study highlights that combining exercise with PNE can lead to greater improvements compared to exercise alone or no intervention for FJA patients. The implementation of PNE in physiotherapy sessions has the potential to offer significant benefits. Furthermore, our results highlight the promising role of telerehabilitation as an effective method for delivering interventions to individuals with FJA.

The relationship between chronic diseases and the intensity and duration of low back pain

BACKGROUND

Low back pain (LBP) is a worldwide problem that affects numerous people and limits their mobility. Several factors, including chronic diseases, increase the risk of developing LBP. To date, the information available about the relationship between chronic diseases and the intensity and duration of LBP is quite limited.

AIM

The aim of the present study was to address the relationship between chronic diseases and both the intensity and duration of LBP.

DESIGN

This is an observational cross-sectional study.

SETTING

The study was conducted in the community of Saudi Arabia.

POPULATION

2181 adult participants (aged 18 years or more, mean age of 33 and standard deviation [SD] of ±11, 61% females) from Saudi Arabia with either recent or recurring LBP participated in the study.

METHODS

The participants of this study were surveyed, and their demographic information was obtained. They were asked whether they had LBP during the past year, and if they had, they were asked about their LBP in terms of the pain intensity on a scale that runs from 0 to 10, where 0 indicates no pain and 10 indicates extreme pain. Further, the participants were asked how long their pain lasted (in days). They were also inquired whether they had any of the following chronic diseases: diabetes mellitus, high blood pressure, hypotension, arthritis, cardiopulmonary diseases, kidney diseases, and hypothyroidism. Logistic regression was used to analyze the relationships between both of LBP's intensity and duration, and the presence of chronic diseases, while adjusting for the potential effect of age and gender.

RESULTS

A total of 2181 adults with either new onset of or recurrent LBP during the past 12 months participated in the present study. Of these, 356 (16%), who had LBP, suffered from one or more of the said chronic diseases. It was found that having one or more chronic diseases had statistically significant relationship with increased LBP's intensity (P=0.002), as well as prolonged duration (P=0.001). In particular, hypertension, arthritis, and hypothyroidism have statistically significant relationship with increased the intensity of the pain (P<0.05). Only, hypertension and arthritis have statistically significant relationship with increased the duration of pain (P≤0.001).

CONCLUSIONS

The presence of chronic diseases was associated with a more intense and longer duration of LBP.

CLINICAL REHABILITATION IMPACT

In view of the results of this study, we expect that those who have chronic diseases will have a longer duration of LBP and more intense pain.

Comparison of positional distraction with stabilisation exercises versus stabilisation exercises alone in the management of lumbar radiculopathy: A randomized controlled-trial

OBJECTIVE

To compare the effects of positional distraction with stabilisation exercises versus stabilisation exercises alone in the management of lumbar radiculopathy.

METHODS

The randomised controlled trial was conducted from July to December 2020 at the Institute of Physical Medicine and Rehabilitation, Dow University of Health Sciences, and the Neurosurgery ward of Civil Hospital, Karachi, and comprised individuals of either gender with lumbar radiculopathy pain who were randomised into positional distraction with stabilisation exercises group A and stabilisation exercise group B. The treatment duration was 3 sessions per week for 8 weeks. Intensity of pain and disability were assessed using the Visual Analogue Scale and the Roland Morris Disability Questionnaire, respectively. Data was analysed using SPSS 21.

RESULTS

Of the 100 patients, 63(63%) were males and 37(37%) were females. Overall, 89(89%) were married. There were 50(50%) subjects in group A with mean age 39.42±6.36 years and 50(%) in group B with mean age 38.80±6.69 years. There was no significant difference in terms of age, gender and marital status between the groups (p>0.05). The study was completed by 96(96%) patients; 48(50%) in each of the 2 groups. Intragroup improvement post-intervention compared to baseline was significant (p<0.001) in both groups. Outcomes in group A were significantly better than in group B (p<0.05).

CONCLUSIONS

Addition of positional distraction to stabilisation exercises was found to have superior effects compared to stabilisation exercise alone on pain and functional disability among patients with lumbar radiculopathy.

The difference in multifidus muscle morphology and motor control in non-specific low back pain with clinical lumbar instability and healthy subjects: A case-control study

BACKGROUND

Low back pain (LBP) with clinical lumbar instability (CLI) is considered a subgroup of back pain. Poor core stability function and/or lack of motor controls are thought to play a role in inappropriate inter-segmental movements and pain. There is no study investigating the changes in the lumbar multifidus muscle (LMM) morphology and motor control in this subgroup of patients.

OBJECTIVE

To assess motor control components and morphological changes of LMM in the patients suffering from chronic nonspecific low back pain (CNSLBP) with CLI.

DESIGN

Observational case-control study.

METHODS

Thirty-two patients suffering from (CNSLBP) with CLI and 32 healthy individuals were included. The muscle force element of lumbar motor control was assessed by using (the active straight-leg raise test, leg lowering test, and Trendelenburg test). Ultrasonography was used to assess changes in the LMM morphology.

RESULTS

There was a significant decrease in motor control (p = 0.0001), an increase in LMM fatty infiltration (p = 0.002), and a decrease in the thickness of LMM in patients suffering from CNSLBP during contraction (p = 0.006), during rest (p = 0.018). The cross-section area of the LMM showed no statistically significant differences during rest on the right and left sides (p = 0.827, 0.220 respectively) and contraction (p = 0.160, 0.278 respectively) between patients and healthy subjects.

CONCLUSION

Motor control and the morphology of LMM in patients with CNSLBP with CLI may provide insight into the mechanisms of underlying pain and their effect on muscle function and structure.

Comparing physical therapy students' attitudes and beliefs regarding chronic low back pain and knee osteoarthritis: an international multi-institutional comparison between 2013 and 2020 academic years

BACKGROUND

In 2013, physical therapy students demonstrated low guideline-adherent recommendations regarding chronic low back pain (CLBP) for spinal pathology, activity, and work.

OBJECTIVES

To assess the differences in physical therapy students' attitudes, beliefs, and adherence to guideline recommendations regarding CLBP and knee osteoarthritis between 2013 and 2020.

METHODS

In 2013 and 2020, second and fourth-year physical therapy students were recruited from 6 Belgian and 2 Dutch institutions. Attitudes and beliefs regarding CLBP and knee OA were evaluated using the Pain Attitudes and Beliefs Scale for Physiotherapists (PABS-PT), the Health Care Providers' Pain and Impairment Relationship Scale (HC-PAIRS), and a questionnaire regarding therapeutic exercise and knee osteoarthritis. A clinical vignette was used to measure guideline-adherent recommendations regarding spinal pathology, activity, and work.

RESULTS

In 2013, 927 second-year and 695 fourth-year students; in 2020, 695 second-year and 489 fourth-year students; were recruited to participate in the study. Compared to 2013, students had less biomedical and stronger biopsychosocial attitudes and beliefs regarding CLBP, more guideline-adherent recommendations for activity, and more biopsychosocial beliefs regarding the benefits of exercise for patients with knee osteoarthritis in both the second and fourth year. Only fourth-year students in 2020 scored significantly better on HC-PAIRS and guideline-adherent recommendation relating to spinal pathology. No differences were found regarding work recommendations.

CONCLUSIONS

Between 2013 and 2020, physical therapy students made a positive shift towards a more biopsychosocial approach to CLBP and knee osteoarthritis management. Guideline-adherent recommendations for CLBP concerning activity improved, however, concerning work and spinal pathology, it remained low.

Improving Rehabilitation Research to Optimize Care and Outcomes for People with Chronic Primary Low Back Pain: Methodological and Reporting Recommendations from a WHO Systematic Review Series

Chronic primary low back pain (CPLBP) is a prevalent and disabling condition that often requires rehabilitation interventions to improve function and alleviate pain. This paper aims to advance future research, including systematic reviews and randomized controlled trials (RCTs), on CPLBP management. We provide methodological and reporting recommendations derived from our conducted systematic reviews, offering practical guidance for conducting robust research on the effectiveness of rehabilitation interventions for CPLBP. Our systematic reviews contributed to the development of a WHO clinical guideline for CPLBP. Based on our experience, we have identified methodological issues and recommendations, which are compiled in a comprehensive table and discussed systematically within established frameworks for reporting and critically appraising RCTs. In conclusion, embracing the complexity of CPLBP involves recognizing its multifactorial nature and diverse contexts and planning for varying treatment responses. By embracing this complexity and emphasizing methodological rigor, research in the field can be improved, potentially leading to better care and outcomes for individuals with CPLBP.

Predictive value of texture analysis on lumbar MRI in patients with chronic low back pain

PURPOSE

The aim of this study was to determine whether MRI texture analysis could predict the prognosis of patients with non-specific chronic low back pain.

METHODS

A prospective observational study was conducted on 100 patients with non-specific chronic low back pain, who underwent a conventional MRI, followed by rehabilitation treatment, and revisited after 6 months. Sociodemographic variables, numeric pain scale (NPS) value, and the degree of disability as measured by the Roland-Morris disability questionnaire (RMDQ), were collected. The MRI analysis included segmentation of regions of interest (vertebral endplates and intervertebral disks from L3-L4 to L5-S1, paravertebral musculature at the L4-L5 space) to extract texture variables (PyRadiomics software). The classification random forest algorithm was applied to identify individuals who would improve less than 30% in the NPS or would score more than 4 in the RMDQ at the end of the follow-up. Sensitivity, specificity, and the area under the ROC curve were calculated.

RESULTS

The final series included 94 patients. The predictive model for classifying patients whose pain did not improve by 30% or more offered a sensitivity of 0.86, specificity 0.57, and area under the ROC curve 0.71. The predictive model for classifying patients with a RMDQ score 4 or more offered a sensitivity of 0.83, specificity of 0.20, and area under the ROC curve of 0.52.

CONCLUSION

The texture analysis of lumbar MRI could help identify patients who are more likely to improve their non-specific chronic low back pain through rehabilitation programs, allowing a personalized therapeutic plan to be established.

Mobile technologies for rehabilitation in non-specific spinal disorders: a systematic review of the efficacy and potential for implementation in low- and middle-income countries

PURPOSE

The aim of this systematic review was primarily to identify the types of mHealth technologies for the rehabilitation of non-specific spinal disorders, second to evaluate their efficacy, and finally to determine their applicability in LMICs.

METHODS

Three databases (Scopus, PubMed, and Web of Science) were searched for randomized controlled trials and clinical trials from January 2012 until December 2022. Studies were found eligible when using mHealth technologies for the rehabilitation of non-specific spinal disorders. To evaluate efficacy, the primary outcome was pain intensity, and the secondary outcomes were disability and quality of life. To evaluate the applicability in LMICs, information about financial and geographical accessibility, offline usability, and languages was extracted.

RESULTS

Fifteen studies were included comprising 1828 participants who suffer from non-specific low back pain (86.05%) and non-specific neck pain (13.95%). Fourteen distinct smartphone-based interventions and two sensor system interventions were found, with a duration ranging from four weeks to six months. All mHealth interventions demonstrated efficacy for the improvement of pain, disability and quality of life in non-specific spinal disorders, particularly low back pain. Five of the evaluated smartphone applications were free of charge accessible and had language features that could be adapted for use in LMICs.

CONCLUSION

mHealth interventions can be used and integrated into the conventional treatment of non-specific spinal disorders in rehabilitation. They have demonstrated efficacy and could be implemented in LMICs with minor adaptations to overcome language barriers and the absolute necessity of the internet.

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.

Recommending swimming to people with low back pain: A scoping review

BACKGROUND

It is common practice for health professionals to recommend swimming to people with low back pain (LBP) despite limited evidence. The aim of this review was to gain an understanding of the current evidence base supporting the recommendation of swimming to people with LBP.

METHODS

A scoping review was conducted searching five electronic databases, CINAHL, MEDLINE, PEDro, PubMed, and SPORTdiscus using the keywords back pain AND swim*. The studies were grouped by study design and the following uncertainties were considered; the impact of swimming on the spine and LBP, evidence of swimming increasing or reducing the risk of LBP and the use of swimming in LBP rehabilitation programmes.

RESULTS

25 studies met the eligibility criteria; including sixteen observational studies exploring the relationship between swimming and LBP, three biomechanical studies investigating the impact of swimming on the spine, and five interventional studies of which four integrated swimming into a rehabilitation programme and one used swimming to modify lumbar lordosis.

CONCLUSION

The review confirmed there is limited research and only low-level evidence to support the recommendation of swimming to people with LBP. Observational studies make up the greater proportion of research undertaken in the field; the data indicates that swimming is a low-risk form of exercise but not without risk. The findings from biomechanical research suggest that lumbar lordosis does not increase excessively when swimming breaststroke, but certain swimming techniques could negatively impact LBP and interventional trials illustrate that there are various ways to integrate swimming into a rehabilitation programme.

First Provider Seen for an Acute Episode of Low Back Pain Influences Subsequent Health Care Utilization

OBJECTIVE

Costs associated with low back pain (LBP) continue to rise. Despite numerous clinical practice guidelines, the evaluation and treatments for LBP are variable and largely depend on the individual provider. As yet, little attention has been given to the first choice of provider. Early research indicates that the choice of first provider and the timing of interventions for LBP appear to influence utilization. We sought to examine the association between the first provider seen and health care utilization.

METHODS

Using 2015-2018 data from a large insurer, this retrospective analysis focused on patients (29,806) seeking care for a new episode of LBP. The study identified the first provider chosen and examined the following year of medical utilization. Cox proportional hazards models were calculated using inverse probability weighting on propensity scores to evaluate the time to event and the relationship to the first choice of provider.

RESULTS

The primary outcome was the timing and use of health care resources. Total health care use was lowest in those who first sought care with chiropractic care or physical therapy. Highest health care use was seen in those patients who chose the emergency department.

CONCLUSION

Overall, there appears to be an association between the first choice of provider and future health care use. Chiropractic care and physical therapy provide nonpharmacologic and nonsurgical, guideline-based interventions. The use of physical therapists and chiropractors as entry points into the health system appears related to a decrease in immediate and long-term use of health resources. This study expands the existing body of literature and provides a compelling case for the influence of the first provider on an acute episode of LBP.

IMPACT

The first provider seen for an acute episode of LBP influences immediate treatment decisions, the trajectory of a specific patient episode, and future health care choices in the management of LBP.

Significant Clinical Improvement Was Predicted in a Cohort of Patients With Low Back Pain Early in the Care Process

OBJECTIVE

The purpose of this study was to determine the proportion of patients with low back pain who achieved clinical improvement in disability within 3 or 6 physical therapy visits, identify factors that predicted improvement, and predict the probability of improvement by the third and sixth visits.

METHODS

This retrospective, observational study looked at patients (N = 6523) who completed a numeric pain scale and Modified Low Back Disability Questionnaire (MDQ) at every visit. Four prediction models were developed: 30% improvement by visit 3 and by visit 6 and 50% improvement by visit 3 and by visit 6. A logistic regression model was fit to predict patients' improvement in disability using the MDQ. Predictive models used age, disability scores, sex, symptom duration, and payer type as factors. Receiver operating characteristic curves and area under the curve were computed for the models. Nomograms illustrate the relative impacts of the predictor variables.

RESULTS

Disability improved 30% in 42.7% of patients by visit 3 and 49% by visit 6. Disability improved 50% in 26% of patients by visit 3 and 32.9% by visit 6. First visit score (MDQ1) was strongest factor to predict 30% improvement by visit 3. The visit 3 score (MDQ3) was strongest factor to predict a 30% or 50% improvement by visit 6. The combination of MDQ1 and MDQ3 scores was strongest overall predictive factor for visit 6. The area under the curve values for models using only the MDQ1 and MDQ3 scores to predict 30% or 50% improvement by the sixth visit were 0.84 and 0.85, respectively, representing excellent overall diagnostic accuracy of the prediction models.

CONCLUSION

Excellent discrimination to predict patients' significant clinical improvement by visit 6 using 2 outcome scores was demonstrated. Gathering outcomes routinely enhances assessment of prognosis and clinical decision making.

IMPACT

Understanding prognosis of clinical improvement supports physical therapists' contribution to value-based care.

Strategies to facilitate and tools to measure non-specific low back pain patients' adherence to physiotherapy - A two-stage systematic review

BACKGROUND

Sustainable management for non-specific low back pain relies on adherence. This requires effective strategies to facilitate but also tools to measure adherence to physiotherapy.

OBJECTIVE

This two-stage systematic review aims to identify (1) tools to measure non-specific back pain patients' adherence to physiotherapy and (2) the most effective strategy to facilitate patients' adherence to physiotherapy.

METHOD

PubMed, Cochrane, PEDro, and Web of Science were searched for English language studies measuring adherence in adults with low back pain. Following PRISMA recommendations, scoping review methods were used to identify measurement tools (stage 1). The effectiveness of interventions (stage 2), followed a predefined systematic search strategy. Two independent reviewers selected eligible studies (software Rayyan), analyzed these for risk of bias using the Downs and Black checklist. Data relevant to assess adherence were collected in a predesigned data extraction table. Results were heterogeneous and hence summarized narratively.

RESULTS

Twenty-one studies were included for stage 1 and 16 for stage 2. Identified were 6 different tools to measure adherence. The most used tool was an exercise diary; the most common more multidimensional tool was the Sports Injury Rehabilitation Adherence Scale. Most included studies were not designed to improve or measure adherence but used adherence as a secondary outcome for new exercise programs. The most promising strategies for facilitating adherence were based on cognitive behavioral principles.

CONCLUSION

Future studies should focus on the development of multidimensional strategies to facilitate adherence to physiotherapy and appropriate tools to measure all aspects of adherence.

The effectiveness of low-dosed outpatient biopsychosocial interventions compared to active physical interventions on pain and disability in adults with nonspecific chronic low back pain: A systematic review with meta-analysis

OBJECTIVE

To evaluate the effectiveness of low-dosed outpatient biopsychosocial interventions versus active physical interventions on pain intensity and disability in adults with nonspecific chronic low back pain.

INTRODUCTION

Research has shown that primary care biopsychosocial interventions (PCBI) can reduce pain intensity and disability. While scattered studies support low-dosed (≤ 15 treatment hours) PCBI, no systematic review exists comparing the effectiveness of low-dosed PCBI treatment with traditional physical activity interventions in adults with nonspecific chronic low back pain (CLBP).

INCLUSION CRITERIA

Randomized controlled trials that evaluate low-dosed PCBI compared to physical treatment with an active component such as exercise, physical activity or usual physiotherapy treatment for adult participants (18 years or older), who suffer from CLBP were included. Not recommended interventions that feature only passive therapies, spinal surgery or pharmacological treatment, and studies with inpatient multidisciplinary-based rehabilitation (MBR) were excluded.

METHODS

Databases were searched from inception to December 31, 2021. Language was restricted to English or German. Keywords and derivatives of "chronic back pain", "exercise intervention", "cognitive-behavioral therapy", "primary care" and "randomized controlled trials" were used. Sources were CINAHL, Cochrane Central Register of Controlled Trials (CENTRAL), Ovid Medline, Physiotherapy Evidence Database (PEDro), PubMed and Web of Science. Search was finished on March 08, 2022. Data appraisal, extraction and synthesis followed JBI guidance for systematic reviews of effectiveness. Risk of Bias was assessed using JBI 13-item checklist for randomized controlled trials. The GRADE approach for grading the certainty of evidence was followed.

SYSTEMATIC REVIEW REGISTRATION NUMBER

PROSPERO 2022 CRD42022302771.

RESULTS

Eighteen RCTs were found eligible and 15 trials comprising a total of 1531 participants suffering from CLBP were entered in the meta-analyses. Risk of Bias was low. Overall evidence was moderate. Significant effects in favor of PCBI were found for pain intensity post-treatment (standardized mean difference (SMD) = -1.09, 95% confidence interval (CI) = -1.84 to -0.34, I2  = 97%, p = 0.004) as well as at short-term (SMD = -0.23, 95% CI = -0.39 to -0.08, I2  = 0%, p = 0.004), long term (SMD = -0.79, 95% CI = -1.42 to -0.17, I2  = 96%, p = 0.01) and very long-term (SMD = -1.13, 95% CI = -1.93 to -0.33, I2  = 94%, p = 0.005) follow-up. Significant effects in favor of PCBI for physical function were found post-treatment (SMD = -1.33, 95% CI = -2.17 to -0.49, I2  = 97%, p = 0.002) at short-term (SMD = -0.20, 95% CI = -0.36 to -0.04, I2  = 0%, p = 0.01) and at long-term follow-up (SMD = -1.17, 95% CI = -2.06 to -0.28, I2  = 98%, p = 0.01). The results were characterized by high heterogeneity due to different types (cognitive behavioral therapy, pain-neuroscience education, mindfulness, and motivation), delivery modes (individual and/or group), durations (3-12 weeks) and contact times (2-15 h) of PCBI. In sensitivity analysis outliers were removed to reduce heterogeneity. The results remained significant for pain intensity at short-term (SMD = -0.23, 95% CI = -0.39 to -0.08, I2  = 0%, p = 0.004) and long-term follow-up (SMD = -0.22, 95% CI = -0.41 to -0.03, I2  = 39%, p = 0.02).

CONCLUSIONS

This meta-analysis suggests that low-dosed PCBI has favorable effects in terms of disability and pain intensity compared to active physical treatments alone. All conducted meta-analyses indicate that biopsychosocial interventions produce better outcomes than active physical treatment alone. Therefore, we strongly recommend decision makers and clinical practitioners to analyze how psychosocial elements can be introduced into outpatient (low-dosed) CLBP interventions.

Adherence and Effect of Home-Based Rehabilitation with Telemonitoring Support in Patients with Chronic Non-Specific Low Back Pain: A Pilot Study

Home-based exercises have been on the rise recently. This pilot study aimed to assess the adherence and effect of a home-based rehabilitation programme using telemonitoring in patients with chronic non-specific low back pain (CNLBP). Twenty-seven patients with CNLBP were enrolled in the study, each of whom underwent a neurological assessment, including patient-oriented measures and a functional assessment-a battery of tests that comprehensively evaluated trunk muscle function. The rehabilitation programme lasted 18 weeks and included daily home-based exercises. A mobile application or an exercise diary was used to monitor compliance. Adherence to the programme was excellent for both the diary and mobile application groups, with 82.3% in the diary group exercising at least once a day and 72.9% twice a day, and 94.8% in the mobile application group exercising at least once a day and 86.6% twice a day. Both patient-oriented and functional outcomes improved significantly; however, the relative changes of the parameters in these two groups did not correlate, which supports the idea that trunk muscle function does not directly relate to patient complaints and that CNLBP is a multifactorial issue. This model of rehabilitation programme should be used in clinical practice, as its adherence and effectiveness seem noticeable.

Clarification of the "pain neuroscience education" concept in the management of patients with persistent low back pain: A scoping review

BACKGROUND

Patient education is a recommended treatment strategy for persistent low back pain (PLBP). Pain neuroscience education (PNE) is an emerging concept with boundaries still unclear.

OBJECTIVE

To clarify the PNE concept and identify its key characteristics in PLBP management.

METHODS

A systematic search was conducted using the following databases: Pubmed, ScienceDirect, Google Scholar, Cochrane, and Pedro.

INCLUSION CRITERIA

publications in English or French on pain neuroscience education and chronic low back pain, educational books cited in white literature. Three reviewers independently selected eligible studies for final inclusion. Numerical analysis and narrative synthesis were carried out from the extracted data.

RESULTS

From 919 identified publications, 54 were selected. Ten educational resources were added. PNE refers to a theoretical framework, a specific educational intervention, and an overall care approach. It is characterized by the intention to help the patient reconceptualize their PLBP from a tissue injury marker to a protective, neurobiological perspective, and then to increase adherence to biopsychosocial rehabilitation and normalize cognitive-behavioral responses. Pain sciences concepts are presented with an optimization of learning strategies.

CONCLUSION

PNE stands out from other educational and cognitive behavioral approaches through its objective of changing the pain concept.

Physical activity for patients with chronic low back pain: What are physical therapists prescribing?

BACKGROUND

Despite the extensive evidence supporting physical activity (PA) for managing chronic low back pain (CLBP), little is known about PA prescription by physical therapists treating patients with CLBP.

OBJECTIVE

1) Explore how PA prescriptions provided by outpatient physical therapists treating patients with CLBP align with PA guidelines. 2) Examine the barriers and facilitators of PA prescription among physical therapists working with patients with CLBP.

METHODS

We conducted a qualitative study with outpatient physical therapists who treat CLBP. Semi-structured interviews provided an understanding of physical therapist experience with PA prescription among patients with CLBP. The interviews were transcribed, coded, and analyzed thematically.

RESULTS

The 18 participants had an average of 13.4 (6.4) years of clinical experience in outpatient physical therapy. Thematic analysis revealed: 1) Physical therapists' articulate knowledge of PA guidelines and importance of physical activity; 2) Patient factors take priority over the PA guidelines for people with CLBP; and 3) The importance of building and maintaining a strong patient-therapist relationship influences physical therapist prescription of PA for patients with CLBP.

CONCLUSION

When providing PA recommendations for patients with CLBP, general movement recommendations are emphasized in place of explicit PA prescriptions. Our findings highlight factors for consideration when prescribing movement and PA for patients with CLBP.

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

OBJECTIVE

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

METHODS

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

RESULTS

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

CONCLUSION

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

IMPACT

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

MODERATING EFFECT OF BODY HEIGHT ON THE ASSOCIATION OF BODY WEIGHT AND DISABILITY CAUSED BY NON SPECIFIC CHRONIC LOW BACK PAIN IN WOMEN AND MEN

The aim of the study was testing the hypothesis that body height has a moderating effect on the association of weight and chronic low back pain (LBP) induced disability, and that this moderating effect is different in women and men. We performed a nested cross-sectional analysis using data collected at baseline in a prospective cohort study conducted in 2008-2009 at a special hospital for medical rehabilitation in Croatia. The outcome was the Roland-Morris Disability Questionnaire (RMDQ) score. The independent variable was body weight. The focal moderators were body height and sex. The moderation analysis was adjusted for seven sociodemographic and clinical covariates. We analyzed data on 72 patients with a median (interquartile range) age of 50 (43-55) years, 36 (50%) of whom were women, treated for nonspecific, chronic LBP. The interaction of sex, body weight and height was a significant predictor of the RMDQ score after adjustments for all covariates (increase of R2=0.13; p=0.001; false discovery rate <5%). In both sexes, the correlation between body weight and the RMDQ score was significantly moderated by body height but in opposite ways. In conclusion, the effects of body weight on physical disability are moderated by body height, but this moderation effect differs between women and men.

Low Back Pain in People With Lower Limb Amputation: A Cross-Sectional Study

STUDY DESIGN

A cross-sectional study based on an online questionnaire.

OBJECTIVE

The aim was to investigate the prevalence and intensity of low back pain (LBP) in people with lower limb amputation (LLA) and to analyze the association factors that can influence the genesis of LBP.

SUMMARY OF BACKGROUND DATA

It is still unclear whether LBP is more prevalent in the amputated population than in its nonamputated counterpart. Given the multifactorial nature of LBP, it is necessary to explore possible factors that can influence its presence and intensity, to build a solid background to define a better rehabilitation pathway for the management of these people.

METHODS

The online questionnaire included six sections: informed consent of the study, demographic information, comorbid conditions, history of LLA, history of LBP, and acceptance of the amputation.

RESULTS

Between March and June 2021, 239 participants [mean age (SD): 49.2 (11.5); female 11%] completed the survey (response rate: 32%). From the results of this study, LBP in LLA showed a prevalence of 82% postamputation and 70% in the last year. A logistic regression with a backward method showed that participants who had problems in the not affected leg presented 1.58 (95% confidence interval: 0.70; 2.45) times higher odds to have LBP after the amputation.

CONCLUSION

This study shows that the prevalence of LBP in lower limb amputees appears to be higher than in the general population, with similar levels of pain intensity and frequency. The highest percentage of people with a sedentary lifestyle not practicing any kind of sports emphasizes the importance of educating this population on the importance of physical activity. New strategies to invest in the education of this population in terms of physical activity are needed.

The Effect of comprehensive rehabilitation on Lithuanian adolescent's nonspecific low back pain, depending on the duration: Nonrandomized single-arm trial

OBJECTIVE

To determine pain and functional changes during comprehensive rehabilitation (CR) in adolescents with nonspecific low back pain (NLBP), and to determine the optimal CR duration.

METHODS

The study included 106 adolescents (39 boys [36.8%], 67 girls [63.2%]), 14 to17 years old, with the following inclusion criteria: duration of NLBP for at least 12 weeks; conservative NLBP treatment was effectless; pain intensity using the visual analogue pain scale (VAS) ≤ 7 points; disrupted daily activities; ability to understand and answer the questions; written consent to participate voluntarily in the study. The pain was assessed using the VAS scale, functional changes were assessed using the Oswestry Disability Index (ODI), 12-Item Short Form Survey, Hospital Anxiety and Depression Scale (HAD), and physical functional capacity and proprioception (Proprio) were assessed using an isokinetic dynamometer. The participants performed a comprehensive pain rehabilitation program consisting of physiotherapy, TENS, magnetotherapy, lumbar massage, and relaxing vibroacoustic therapy. The active CR cycle lasted for 22 sessions (with intermediate measurements after 5 and 16 sessions), after which we performed passive observation for another half a year. Five measurements were performed.

RESULTS

Pain, functional assessment, and physical capacity were improved with CR. Statistically significant improvement became apparent after 5 CR sessions, but statistical and clinical significance became apparent after 16 CR sessions. In the distant period, after the completion of CR, neither statistical nor clinical changes occurred.

CONCLUSIONS

CR is effective in reducing pain, and improving functional state and physical capacity quickly and reliably in 16 CR sessions, which is sufficient to obtain clinically satisfactory CR results. Good results were achieved during CR and neither improved nor deteriorated spontaneously in the distant period. This study shows a possible mismatch between NLBP intensity and impaired functional state in adolescents.

Bilateral Asymmetrical Limb Proprioceptive Neuromuscular Facilitation Effects on Pain, Multifidus Activity, Range of Motion, and Disability in Low Back Pain: A Randomized Controlled Trial

OBJECTIVE

The purpose of this study was to determine the effects of bilateral asymmetrical limb proprioceptive neuromuscular facilitation (PNF) pattern exercises on lumbar multifidus (LM) activity, pain, disability, and lumbar range of motions (ROMs) compared to Swiss ball exercises in patients with chronic low back pain (CLBP).

METHODS

A randomized controlled trial was conducted at the Sindh Institute of Physical Medicine and Rehabilitation, Karachi, Pakistan, between March 2020 and January 2021. A sample size of 150 patients with CLBP was randomized into 2 groups. Participants in the intervention group (n = 75) received bilateral asymmetrical limb PNF, while the comparison group (n = 75) received Swiss ball exercises. The scores of the visual analog scale, Oswestry Disability Index, Modified-Modified Schober's test, and percentage of the maximum voluntary contractions of LM (%MVC LM) through surface electromyography were recorded before and after 15 sessions of exercises. The Wilcoxon signed rank and Mann-Whitney U tests were employed for within-group and between-group comparisons of all outcomes, respectively. The considered level of significance was 0.05. The trial was registered with ClinicalTrials.gov (NCT04206137).

RESULTS

Pain (in sitting, standing, and walking), disability on the Oswestry Disability Index, and left side %MVC LM were significantly improved (P < .001) in the PNF group compared to the comparison group except for right side %MVC LM and ROMs on the Modified-Modified Schober's test (P > .05).

CONCLUSION

Bilateral asymmetrical limb PNF exercises showed improvement in pain, disability, and LM activity of patients with CLBP more than those who used Swiss ball exercises.

Effect of Graded Sensorimotor Retraining on Pain Intensity in Patients With Chronic Low Back Pain: A Randomized Clinical Trial

IMPORTANCE

The effects of altered neural processing, defined as altering neural networks responsible for perceptions of pain and function, on chronic pain remains unclear.

OBJECTIVE

To estimate the effect of a graded sensorimotor retraining intervention (RESOLVE) on pain intensity in people with chronic low back pain.

DESIGN, SETTING, AND PARTICIPANTS

This parallel, 2-group, randomized clinical trial recruited participants with chronic (>3 months) nonspecific low back pain from primary care and community settings. A total of 276 adults were randomized (in a 1:1 ratio) to the intervention or sham procedure and attention control groups delivered by clinicians at a medical research institute in Sydney, Australia. The first participant was randomized on December 10, 2015, and the last was randomized on July 25, 2019. Follow-up was completed on February 3, 2020.

INTERVENTIONS

Participants randomized to the intervention group (n = 138) were asked to participate in 12 weekly clinical sessions and home training designed to educate them about and assist them with movement and physical activity while experiencing lower back pain. Participants randomized to the control group (n = 138) were asked to participate in 12 weekly clinical sessions and home training that required similar time as the intervention but did not focus on education, movement, and physical activity. The control group included sham laser and shortwave diathermy applied to the back and sham noninvasive brain stimulation.

MAIN OUTCOMES AND MEASURES

The primary outcome was pain intensity at 18 weeks, measured on an 11-point numerical rating scale (range, 0 [no pain] to 10 [worst pain imaginable]) for which the between-group minimum clinically important difference is 1.0 point.

RESULTS

Among 276 randomized patients (mean [SD] age, 46 [14.3] years; 138 [50%] women), 261 (95%) completed follow-up at 18 weeks. The mean pain intensity was 5.6 at baseline and 3.1 at 18 weeks in the intervention group and 5.8 at baseline and 4.0 at 18 weeks in the control group, with an estimated between-group mean difference at 18 weeks of -1.0 point ([95% CI, -1.5 to -0.4]; P = .001), favoring the intervention group.

CONCLUSIONS AND RELEVANCE

In this randomized clinical trial conducted at a single center among patients with chronic low back pain, graded sensorimotor retraining, compared with a sham procedure and attention control, significantly improved pain intensity at 18 weeks. The improvements in pain intensity were small, and further research is needed to understand the generalizability of the findings.

Movement Analysis Could Help in the Assessment of Chronic Low Back Pain Patients: Results from a Preliminary Explorative Study

Introduction: This study aimed to assess the reliability of a qualitative scoring system based on the movement analysis of the spine in different populations and after usual care rehabilitative intervention. If proven true, the results could further future research development in quantitative indexes, leading to a possible subclassification of chronic low back pain (cLBP). Methods: This was a preliminary exploratory observational study. Data of an optoelectronic spine movement analysis from a pathological population (cLBP population, 5 male, 5 female, age 58 ± 16 years) were compared to young healthy participants (5M, 5F, age 22 ± 1) and were analysed via a new qualitative score of the pattern of movement. Internal consistency was calculated. Two independent assessors (experienced and inexperienced) assessed the blinded data, and we calculated inter- and intrarater reliability. We performed an analysis for cLBP pre and post a ten session group rehabilitation program between and within groups. Results: Internal consistency was good for all movements (α = 0.84-0.88). Intra-rater reliability (Intraclass correlation coefficient-ICC) was excellent for overall scores of all movements (ICC_(1,k) = 0.95-0.99), while inter-rater reliability was poor to moderate (ICC_(1,k) = 0.39-0.78). We found a significant difference in the total movement scores between cLBP and healthy participants (p = 0.001). Within-group comparison (cLBP) showed no significant difference in the total movement score in pre and post-treatment. Conclusion: The perception of differences between normal and pathological movements has been confirmed through the proposed scoring system, which proved to be able to distinguish different populations. This study has many limitations, but these results show that movement analysis could be a useful tool and open the door to quantifying the identified parameters through future studies.

Intravoxel incoherent motion imaging predicts exercise-based rehabilitation response in individuals with low back pain

Exercises to strengthen and stabilize the trunk musculature are a common conservative treatment strategy for low back pain (LBP), despite the possible presence of impairments in muscle activation in this population. Intravoxel incoherent motion (IVIM) MRI permits evaluation of activation-induced blood flow through diffusion-weighted images that are sensitized to microvascular blood flow. In the current study we aimed to evaluate IVIM signal changes after exercise in patients with LBP compared with pain-free healthy controls and determine if these changes were related to reductions in disability with a 12-week rehabilitation program. We hypothesize that the magnitude of changes in IVIM parameters in the lumbar extensor muscles will be smaller in patients with LBP compared with those without LBP, and that these magnitudes will be correlated with responsiveness to a 12-week, resistance-based exercise program. IVIM MR data for molecular diffusion (D), blood flow pseudodiffusion (D*) and perfusion fraction (f) were collected before and immediately after an ~ 3-min session of high-intensity lumbar extension resistance exercise in 16 healthy participants and 17 participants with LBP. Improvements in LBP-related disability after the 12-week, machine-based, high-intensity exercise rehabilitation program were measured in the LBP group. We observed a significant increase in all IVIM parameters (f, D*, D) in response to exercise (p < 0.0001) and an interaction of group-by-time for D (p = 0.016). Thresholds were identified using receiver operating characteristic (ROC) curves for diffusion and pseudodiffusion coefficients, which predicted a reduction in LBP-related disability in response to the 12-week, exercise-based rehabilitation program. Exercise was associated with an increase in (f), capillary blood flow-based pseudodiffusion (D*) and diffusion coefficient (D), regardless of the presence of LBP. Additionally, subgroup analysis identified patients who were not responsive to the acute exercise session, for whom, based on ROC analysis, there was no clinically significant change in disability following the 12-week program.

Recovery of the lumbopelvic movement and muscle recruitment patterns using motor control exercise program in people with chronic nonspecific low back pain: A prospective study

This study aims to investigate the dysfunction and recovery of the lumbopelvic movement and motor control of people with chronic nonspecific low back pain after a structured rehabilitation which emphasizes on re-education and training of movement and motor control. The lumbopelvic movement and motor control pattern of 30 adults (15 with chronic low back pain, 15 healthy controls) were assessed using 3D motion and electromyographic analysis during the repeated forward bending test, in additional to the clinical outcome measures. Regional kinematics and muscle recruitment pattern of the symptomatic group was analysed before and after the 6-week rehabilitation, and compared to healthy controls. Significant improvement in back pain, functional capacity and self-efficacy of the symptomatic group was found after the rehabilitation. Patients with chronic nonspecific low back pain were capable to recover to a comparable level of the healthy controls in terms of their lumbopelvic movement and motor control pattern upon completion of a 6-week rehabilitation program, despite their dysfunction displayed at baseline. Phase specific motor control reorganization in which more profound and positive changes shown during the flexion phase. Our findings indicate that the recovery of the movement and motor control pattern in patients with chronic low back pain achieved to a comparable level of the healthy able-bodies. The improvement of both the physical outcome measures suggest that specific rehabilitation program which emphasizes on optimizing motor control during movements would help promoting the functional recovery of this specific low back pain subgroup.

Yoga, Eurythmy Therapy and Standard Physiotherapy (YES-Trial) for Patients With Chronic Non-specific Low Back Pain: A Three-Armed Randomized Controlled Trial

We aimed to evaluate the effects of yoga and eurythmy therapy compared to conventional physiotherapy exercises in patients with chronic low back pain. In a three-armed, multicentre, randomized controlled trial, patients with chronic low back pain were treated for 8 weeks in group sessions (75 minutes once per week). Primary outcome was patients' physical disability (measured by RMDQ) from baseline to week 8. Secondary outcome variables were pain intensity and pain-related bothersomeness (VAS), health-related quality of life (SF-12) and life satisfaction (BMLSS). Outcomes were assessed at baseline, after the intervention at 8 weeks and at a 16-week follow up. Data of 274 participants were used for statistical analyses. There were no significant differences between the three groups for the primary and all secondary outcomes. In all groups, RMDQ decreased comparably at 8 weeks, but did not reach clinical meaningfulness. Pain intensity and pain-related bothersomeness decreased, while quality of life increased in all 3 groups. In explorative general linear models for the SF-12's mental health component participants in the eurythmy arm benefitted significantly more compared to physiotherapy and yoga. Furthermore, within-group analyses showed improvements of SF-12 mental score for yoga and eurythmy therapy only. All interventions were safe. Clinical Trials Register: DRKS-ID: DRKS00004651 Perspective: This article presents the results of a multicentre three-armed randomized controlled trial on the clinical effects of three 8-week programs in patients with chronic low back pain. Compared to the 'gold standard' of conventional physiotherapeutic exercises, eurythmy therapy and yoga therapy lead to comparable symptomatic improvements in patients with chronic low back pain. However, the within-group effect sizes were small to moderate and did not reach clinical meaningfulness on patients' physical disability (RMDQ).

Lumbar Bracing for Chronic Low Back Pain: A Randomized Controlled Trial

PURPOSE

We performed this study to evaluate the effect of back bracing to treat patients with chronic low back pain.

METHODS

This was a prospective, unblinded, randomized controlled trial of 61 adults with uncomplicated chronic low back pain (>12 wks) and imaging findings of degenerative spondylosis, to assess the effectiveness of a semirigid back brace. All study participants received back school instruction. The treatment group also received a lumbar orthosis and was instructed to wear it as needed for symptom relief. At baseline, 6 wks, 12 wks, and 6 mos after intervention, we collected: Numerical Rating Scale to measure pain intensity, Pain Disability Questionnaire, Patient-Reported Outcome Measurement Information System, and EuroQol 5-Dimension (EQ-5D) to measure patient-reported function and quality of life.

RESULTS

An interim analysis at the halfway point in enrollment (61 of 120 planned participants) revealed the Pain Disability Questionnaire, Patient-Reported Outcome Measurement Information System, and EQ-5D scores in the treatment group to be worse than in the control group, but no significant group differences in Numerical Rating Scale scores. Outcome differences between groups analyzed over time revealed (effect [P]): Pain Disability Questionnaire = 0.84 (0.04); Patient-Reported Outcome Measurement Information System = 0.78 (0.005); EQ-5D = 0.06 (0.01); and Numerical Rating Scale = 0.02 (0.6). We halted the study because continuation was unlikely to produce significant changes to the results.

CONCLUSIONS

In patients with uncomplicated chronic low back pain, a back brace when combined with education and exercise instruction did not provide any pain relief compared with education and exercise instruction alone.

Medial Prefrontal High-Definition Transcranial Direct Current Stimulation to Improve Pain Modulation in Chronic Low Back Pain: A Pilot Randomized Double-blinded Placebo-Controlled Crossover Trial

Chronic low back pain (CLBP) is highly disabling, but often without identifiable source. Focus has been on impaired anti-nociceptive mechanisms contributing to pain maintenance, though methods of targeting this impairment remain limited. This randomised-controlled cross-over pilot trial used active versus sham medial prefrontal cortex (mPFC) high-definition transcranial direct current stimulation (HD-tDCS) for 3-consecutive days to improve descending pain inhibitory function. Twelve CLBP patients were included with an average visual analogue scale (VAS) pain intensity of 3.0 ± 1.5 and pain duration of 5.3 ± 2.6 years. Pressure pain thresholds (PPTs), conditioned pain modulation (CPM), and temporal summation of pain (TSP) assessed by cuff algometry, as well as pain symptomatology (intensity, unpleasantness, quality, disability) and related psychological features (pain catastrophizing, anxiety, affect), were assessed on Day1 before 3 consecutive days of HD-tDCS sessions (each 20 minutes), at 24-hours (Day 4) and 2-weeks (Day 21) following final HD-tDCS. Blinding was successful. No significant differences in psychophysical (PPT, CPM, TSP), symptomatology or psychological outcomes were observed between active and sham HD-tDCS on Day4 and Day21. CPM-effects at Day 1 negatively correlated with change in CPM-effect at Day4 following active HD-tDCS (P = .002). Lack of efficacy was attributed to several factors, not least that patients did not display impaired CPM at baseline. TRIAL REGISTRATION: : ClinicalTrials.gov (NCT03864822). PERSPECTIVE: Medial prefrontal HD-tDCS did not alter pain, psychological nor psychophysical outcomes, though correlational analysis suggested response may depend on baseline pain inhibitory efficacy, with best potential effects in patients with severe impairments in descending pain inhibitory mechanisms. Future work should focus on appropriate patient selection and optimising stimulation targeting.

Comparative efficacy of 12 non-drug interventions on non-specific chronic low back pain in nurses: A systematic review and network meta-analysis

BACKGROUND

Many non-drug interventions for decreasing non-specific chronic low back pain (NSCLBP) in nurses have been extensively studied, but the most effective approach is still unclear.

OBJECTIVE

This systematic review and network meta-analysis evaluated the efficacies of 12 non-drug interventions in reducing NSCLBP in nurses.

METHODS

PubMed, ScienceDirect, Web of Science, Cochrane, EMBASE, CINAHL, Medline, WANFANG, VIP, China Knowledge Integrated, and SinoMed were searched from their establishment to July 2019. Randomized controlled trials (RCTs) comparing non-drug interventions for NSCLBP in nurses were included and analyzed using Stata v15 statistical software.

RESULTS

A total of 31 RCTs (n= 7116) and 12 non-drug interventions were included. The first three results with the highest surface areas under the curve ranking area (SUCRAs) were low back exercise plus healthy education, single low back exercise, and yoga (SUCRAs: 79.4%, 76.2%, and 75.1%, respectively). In addition, single yoga was inferior to protective equipment (standardized mean difference [SMD] = 3.88, 95% confidence interval [CI]: 0.92 to 6.84) and multidisciplinary intervention (SMD =-4.06, 95% CI: -7.33 to -0.78).

CONCLUSIONS

Low back exercise plus health education may be the best approach to reduce NSCLBP in nurses. Considering the heterogeneity, our findings need to be confirmed in future multicenter large sample RCTs in different countries.

The influence of pain, kinesiophobia and psychological comorbidities on the accuracy of rating of perceived exertion in UK military spinal rehabilitation

INTRODUCTION

Chronic low back pain (CLBP) is a leading cause of disability in the UK Military. Pain and psychological comorbidities have been reported to influence the rating of perceived exertion (RPE). Exercise rehabilitation can be monitored using RPE; however, the accuracy of RPE in inpatient CLBP rehabilitation is unknown.

METHODS

A prospective cohort correlation study of 40 UK Military inpatients with CLBP was completed. Disability (ODI), kinesiophobia (TSK), anxiety (GAD-7) and depression (PHQ-9) were subjectively reported at the beginning and end of a 3 week intervention. Pain (VAS) and HR were recorded in the first aerobic exercise (AE) session (T1) and the final aerobic exercise session (T2). RPE was reported for each AE session.

RESULTS

At T1, a positive correlation was observed between RPE accuracy (-7.2±20.9), and pre-exercise pain (2.7 mm ±1.6 mm) (p>0.001) and ODI (31.0±16.9) (p>0.05), and a negative relationship between RPE accuracy and average HR (135 bpm ±22 bpm) (p>0.001) was observed. At T2, there was no significant correlation between RPE accuracy (-4.4±22.6) and pre-exercise pain (2.8 mm ±1.6 mm) or ODI (34.0±16.5) (p>0.05). The strong negative relationship between RPE accuracy and average HR (137 bpm ±20 bpm) remained at T2. Improved RPE accuracy over the 3-week rehabilitation programme was correlated to the change in average HR (r=-0.314, p<0.05).

CONCLUSIONS

Comorbidities may negatively affect RPE accuracy in CLBP, but the magnitude of the influence reduces over intensive rehabilitation.

Meta-epidemiological study of publication integrity, and quality of conduct and reporting of randomized trials included in a systematic review of low back pain

OBJECTIVE

To comprehensively describe the quality of conduct, reporting, and publication integrity characteristics for all trials included in a large Cochrane review, comparing those published by presumed predatory publishers with those published by nonpredatory publishers.

DESIGN

Cross-sectional meta-epidemiological study.

STUDY SELECTION

Two hundred seventy-nine studies (25,704 participants) eligible for the recent update of the "Exercise therapy for chronic low back pain" Cochrane review were included.

DATA EXTRACTION

Study and manuscript characteristics, including predatory publication status and other quality and integrity characteristics were extracted along with treatment effect.

RESULTS

Nine percent of trials included were in presumed predatory publications; 12% in the period since 2010. We found frequency of other concerning characteristics to range from low (eg, plagiarism, 5%) to common (eg, lack of evidence of trial registration or protocol publication [75%]; insufficient sample size [84%]) in included studies. Studies published by presumed predatory publishers consistently had inferior conduct, reporting and publication integrity characteristics. Presumed predatory publication was associated with missing conflict of interest statement (OR 7.6, 95% CI 3.0-19.1), inadequate follow-up duration (OR 11.2, 95% CI 3.7-33.7), incomplete study methods (OR 12.1, 95% CI 2.8-52.2) and baseline reporting (OR 4.3, 95% CI 1.6-11.7), and high risk of bias (OR 2.7, 95% CI 1.2-6.3). All (100%) presumed predatory publications were missing trial registrations (vs. 72%) and had inadequate sample sizes (vs. 82%). Trials published in presumed predatory journals did not appear to have inflated effect sizes.

CONCLUSIONS

Predatory publishers pose a distinct challenge to the consumption and synthesis of randomized controlled trials. More work is needed in other clinical areas to understand the potential impact of randomized controlled trials published in predatory publications, and as a result, the potential impact on evidence from systematic reviews that include these studies.

Crosswalking the Patient-Reported Outcomes Measurement Information System Physical Function, Pain Interference, and Pain Intensity Scores to the Roland-Morris Disability Questionnaire and the Oswestry Disability Index

OBJECTIVE

To link scores from 2 condition-specific measures for chronic low back pain (CLBP), the Oswestry Disability Index (ODI) and the Roland-Morris Disability Questionnaire (RMDQ), to Patient Reported Outcomes Measurement Information System (PROMIS) physical function, pain interference, and pain intensity scores.

DESIGN

Ordinary least squares regression analyses of existing data to link the PROMIS scores with the ODI and RMDQ.

SETTING

Not applicable.

PARTICIPANTS

Samples of adults with CLBP (N=2279) obtained from the Center for Excellence in Research for Complementary and Integrative Health (CERC) Study (n=1677), the Assessment of Chiropractic Treatment for Low Back Pain and Smoking Cessation in Military Active Duty Personnel (ACT) (n=384), and the pain subsample of the PROMIS 1 Wave 2 Pain and Depression study (PROMIS 1 W2) (n=218).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

PROMIS physical function, pain interference, and pain intensity (CERC, ACT, and PROMIS 1 W2), ODI (CERC and PROMIS 1 W2), and RMDQ (ACT and PROMIS 1 W2).

RESULTS

In predicting PROMIS scores, the ODI model R² values ranged from 0.26-0.56 and the RMDQ model R² values ranged from 0.13-0.50. ODI and RMDQ models were the least precise in predicting the PROMIS pain intensity score (R² value range, 0.13-0.41) relative to the other PROMIS scores. Models with the 3 PROMIS scores as predictors yielded R² values ranging from 0.64-0.68 and 0.46-0.58 for the ODI and RMDQ, respectively. Models using combined data from 2 studies (ie, PROMIS 1 W2 and ACT, or PROMIS 1 W2 and CERC) tended to be more precise than models using only a single study sample.

CONCLUSIONS

Model results reported here can be used to translate PROMIS physical function, pain interference, and pain intensity scores to and from the ODI and RMDQ. The empirical linkages can facilitate comparisons across CLBP interventions and broaden interpretation of study results.

Temporal Trends and Geographic Variations in the Supply of Clinicians Who Provide Spinal Manipulation to Medicare Beneficiaries: A Serial Cross-Sectional Study

OBJECTIVE

Spinal manipulation (SM) is recommended for first-line treatment of patients with low back pain. Inadequate access to SM may result in inequitable spine care for older US adults, but the supply of clinicians who provide SM under Medicare is uncertain. The purpose of this study was to measure temporal trends and geographic variations in the supply of clinicians who provide SM to Medicare beneficiaries.

METHODS

Medicare is a US government-administered health insurance program that provides coverage primarily for older adults and people with disabilities. We used a serial cross-sectional design to examine Medicare administrative data from 2007 to 2015 for SM services identified by procedure code. We identified unique providers by National Provider Identifier and distinguished between chiropractors and other specialties by Physician Specialty Code. We calculated supply as the number of providers per 100 000 beneficiaries, stratified by geographic location and year.

RESULTS

Of all clinicians who provide SM to Medicare beneficiaries, 97% to 98% are doctors of chiropractic. The geographic supply of doctors of chiropractic providing SM services in 2015 ranged from 20/100 000 in the District of Columbia to 260/100 000 in North Dakota. The supply of other specialists performing the same services ranged from fewer than 1/100 000 in 11 states to 8/100 000 in Colorado. Nationally, the number of Medicare-active chiropractors declined from 47 102 in 2007 to 45 543 in 2015. The count of other clinicians providing SM rose from 700 in 2007 to 1441 in 2015.

CONCLUSION

Chiropractors constitute the vast majority of clinicians who bill for SM services to Medicare beneficiaries. The supply of Medicare-active SM providers varies widely by state. The overall supply of SM providers under Medicare is declining, while the supply of nonchiropractors who provide SM is growing.

The immediate effect of the abdominal drawing-in maneuver technique on stature change in seated sedentary workers with chronic low back pain

Many studies have measured stature change arising from loads imposed on the spine during sitting. To improve stature recovery, it is important to stabilise the lumbar spine and compensate forces from the upper body. The abdominal drawing-in maneuver (ADIM) technique has been found to mainly activate deep trunk muscles. The purpose of this study was to determine whether activation of deep trunk muscles by the ADIM technique could immediately improve stature recovery during prolonged sitting. Twenty-four patients with chronic low back pain (CLBP) were randomly allocated into different orders of experimental conditions: control (sitting without ADIM technique) and intervention conditions (sitting with ADIM technique). The latter condition required participants to complete ADIM technique for 1 min and repeat it three times throughout 41 min prolonged sitting time. Stature recovery was improved by 3.292 mm in the intervention condition compared with control condition (p-value = 0.001). Our finding demonstrated that ADIM technique improved stature recovery. Practitioner Summary: Prolonged sitting seemingly harms sedentary workers' health, particularly affecting the lower back. Activation of deep trunk muscles using abdominal drawing-in maneuver technique can promote spinal recovery. Clinicians can teach abdominal drawing-in maneuver technique to activate deep trunk muscles in chronic low back pain, thereby promoting self-management of seated stature recovery. Abbrevations: ADIM: abdominal drawing-in maneuver; RA: rectus abdominis; ICLT: iliocostalis lumborum pars thoracis; LM: lumbar multifidus; TrA: transversus abdominis; IO: internal oblique; CLBP: chronic low back pain; LBP: low back pain; RMDQ: Roland Morris disability questionnaire; NRS: numerical rating scale.

Comparing the effectiveness of group-based exercise to other non-pharmacological interventions for chronic low back pain: A systematic review

Background

Low back pain (LBP) is the leading cause of disability worldwide with a substantial financial burden on individuals and health care systems. To address this, clinical practice guidelines often recommend non-pharmacological, non-invasive management approaches. One management approach that has been recommended and widely implemented for chronic LBP is group-based exercise programs, however, their clinical value compared with other non-pharmacological interventions has not been investigated systematically.

Objective

To compare the effectiveness of group-based exercise with other non-pharmacological interventions in people with chronic LBP.

Methods

Four electronic databases were searched by two independent reviewers. Only randomized controlled trials that compared group-based exercise with other non-pharmacological interventions for chronic LBP were eligible. Study quality was assessed using the Cochrane Handbook for systematic reviews of Interventions by two independent reviewers.

Results

Eleven studies were eligible. We identified strong evidence of no difference between group exercise and other non-pharmacologic interventions for disability level and pain scores 3-month post-intervention in people with chronic LBP. We could not find any strong or moderate evidence for or against the use of group-based exercise in the rehabilitation of people with chronic LBP for other time-points and health measurement outcomes. We found no statistically significant differences in disability and quality of life and pain between the group and individual non-pharmacological interventions that included exercise.

Conclusion

With this equivocal finding, group-based exercise may be a preferred choice given potential advantages in other domains not reviewed here such as motivation and cost. Further research in this area is needed to evaluate this possibility.

Comparison of Subjective Responses of Low Back Pain Patients and Asymptomatic Controls to Use of Spinal Exoskeleton during Simple Load Lifting Tasks: A Pilot Study

Spinal exoskeletons have been suggested as an approach for the prevention and rehabilitation of occupational low back pain (LBP). While the state-of-the-art exoskeletons were shown to substantially unload the back, user acceptance is still limited. Perceived discomfort and restriction of freedom of movement are commonly reported. In this pilot study, we explored the differences in subjective responses and user impressions to using passive spinal exoskeleton during a set of simple lifting tasks between LBP patients (n = 12) and asymptomatic individuals (n = 10). Visual analog scales (0-10) were used for all assessments. Overall, the results showed mostly similar responses or slightly more positive responses to the exoskeleton from LBP patients. Most notably, the LBP patients reported a statistically significant (p = 0.048) higher willingness to use the device daily (5.36 ± 4.05) compared to the control group (2.00 ± 1.85) and also gave the device a higher overall grade (6.58 ± 1.98 vs. 4.30 ± 2.26; p = 0.021). This study has demonstrated that individuals with current LBP responded more favorably to the use of the spinal exoskeleton for simple lifting tasks. This implies that current exoskeletons could be appropriate for LBP rehabilitation, but not preventions, as pain-free individuals are less willing to use such devices. Future studies should explore whether different exoskeleton designs could be more appropriate for people with no LBP issues.

Trajectoires de personnes souffrant de lombalgie chronique : ruptures et reconstructions après un programme de rééducation

Purpose of research: The objective of this article is to investigate, from the perspective of patients, the disruptions of the biographical trajectories induced by chronic low back pain and the impact of&#160;a&#160;multidisciplinary rehabilitation program on their reconstruction.

METHODS

Based on an interdisciplinary qualitative research, we investigated the experience of 20 participants with chronic low back pain following a three-week rehabilitation program at the hospital. Semi-directive interviews were conducted before and after inclusion in the program.

RESULTS

Although affecting each person in a singular way, chronic low back pain induces biographical linearity disruptions related to the apparition of pain, and the disruption of daily and professional activities. For the majority of participants, the rehabilitation program provided a repairative space to restore continuity between past, present and future life. Whether or not there is a significant improvement in pain, most participants report benefits that give them the feeling of getting back to normality. Nevertheless, they identify those more for the domestic, family, and social spheres than at the professional level, effects remaining moderate to mitigated in that area.

CONCLUSIONS

The rehabilitation program influences the dynamics of biographical trajectories and promotes a return to what is perceived as normality. By providing individuals with theoretical and practical tools and increasing their functional capacities, it promotes autonomous pain and problem management. Immediate effects are seen as restorative for domestic, family and social activities, but remain limited on the professional level.

Physiotherapists' pain attitudes and beliefs towards chronic low back pain and their association with treatment selection: a cross-sectional study

OBJECTIVES

The main aim of this study was to investigate physiotherapists' pain attitudes and beliefs towardss non-specific chronic low back pain (NSCLBP) and identify whether they are associated with treatment selection.

DESIGN

Cross-sectional study.

SETTING

Saudi Arabia (SA).

PARTICIPANTS

An online survey was distributed to physiotherapists from April 2018 to January 2019. PRIMARY AND SECONDARY OUTCOME MEASURES: (1) Biomedical and biopsychosocial treatment orientations were assessed using the Pain Attitudes and Beliefs Scale for Physiotherapists. (2) Frequent potential treatments used by physiotherapists for individuals with NSCLBP were identified through a 20-item survey. (3) The association between physiotherapists' pain attitudes and beliefs and treatment selection was investigated. Descriptive analysis, Pearson's correlation and multinomial logistic regression were used to analyse the data using SPSS (V.26).

RESULTS

A total of 304 responses were included in the analysis. The biomedical (34.45±7.84) and biopsychosocial (31.74±5.67) treatment orientations were relatively low. The most frequent treatments used by physiotherapists were home exercises (87.1%), patient education (82.0%), specific back exercises (80.6%), electrotherapy (61.9%), soft tissue release (58.8%) and spinal mobilisation or manipulation (57.8%). Physiotherapists with a stronger biomedical treatment orientation were more likely to use treatments (p<0.05) such as specific back exercises, electrotherapy, soft tissue release, hydrotherapy, massage, lumbar supports and acupuncture. However, physiotherapists with a stronger biopsychosocial treatment orientation were more likely to use cognitive functional therapy (p<0.01).

CONCLUSIONS

Biomedical and biopsychosocial treatment orientations were relatively low among physiotherapists in SA. Although treatments such as home exercises and patient education were frequently used, some passive and traditional treatments not recommended by clinical practice guidelines continue to be commonly used by physiotherapists in SA. This study has confirmed that physiotherapists' pain attitudes and beliefs are significantly associated with treatment selection when managing individuals with NSCLBP.

Effectiveness and cost-effectiveness of stratified blended physiotherapy in patients with non-specific low back pain: study protocol of a cluster randomized controlled trial

BACKGROUND

Patient education, advice on returning to normal activities and (home-based) exercise therapy are established treatment options for patients with non-specific low back pain (LBP). However, the effectiveness of physiotherapy interventions on physical functioning and prevention of recurrent events largely depends on patient self-management, adherence to prescribed (home-based) exercises and recommended physical activity behaviour. Therefore we have developed e-Exercise LBP, a blended intervention in which a smartphone application is integrated within face-to-face care. E-Exercise LBP aims to improve patient self-management skills and adherence to exercise and physical activity recommendations and consequently improve the effectiveness of physiotherapy on patients' physical functioning. The aim of this study is to investigate the short- (3 months) and long-term (12 and 24 months) effectiveness on physical functioning and cost-effectiveness of e-Exercise LBP in comparison to usual primary care physiotherapy in patients with LBP.

METHODS

This paper presents the protocol of a prospective, multicentre cluster randomized controlled trial. In total 208 patients with LBP pain were treated with either e-Exercise LBP or usual care physiotherapy. E-Exercise LBP is stratified based on the risk for developing persistent LBP. Physiotherapists are able to monitor and evaluate treatment progress between face-to-face sessions using patient input from the smartphone application in order to optimize physiotherapy care. The smartphone application contains video-supported self-management information, video-supported exercises and a goal-oriented physical activity module. The primary outcome is physical functioning at 12-months follow-up. Secondary outcomes include pain intensity, physical activity, adherence to prescribed (home-based) exercises and recommended physical activity behaviour, self-efficacy, patient activation and health-related quality of life. All measurements will be performed at baseline, 3, 12 and 24 months after inclusion. An economic evaluation will be performed from the societal and the healthcare perspective and will assess cost-effectiveness of e-Exercise LBP compared to usual physiotherapy at 12 and 24 months.

DISCUSSION

A multi-phase development and implementation process using the Center for eHealth Research Roadmap for the participatory development of eHealth was used for development and evaluation. The findings will provide evidence on the effectiveness of blended care for patients with LBP and help to enhance future implementation of blended physiotherapy.
