Measures of function in low back pain/disorders: Low Back Pain Rating Scale (LBPRS), Oswestry Disability Index (ODI), Progressive Isoinertial Lifting Evaluation (PILE), Quebec Back Pain Disability Scale (QBPDS), and Roland-Morris Disability Questionnaire (RDQ)

Standardized screening of cognitive and affective tendencies in persons with low back pain: A knowledge translation project

BACKGROUND

The use of screening questionnaires (SQ) to evaluate affective or cognitive tendencies (CAT) in persons with low back pain (LBP) is recommended by clinical practice guidelines (CPG) yet few physical therapists (PTs) have adopted these recommendations.

OBJECTIVE

To develop and implement a tailored knowledge translation (KT) intervention in an outpatient rehabilitation practice to facilitate the uptake of SQ for CAT in persons with LBP.

METHODS

In a mixed-methods study, using the knowledge to action framework, PTs (n = 12) collaborated with research clinicians to improve the use of three SQ: 1) Primary Care Evaluation of Mental Disorders for Depressive Symptoms; 2) Fear-Avoidance Beliefs Questionnaire; and 3) Pain Catastrophizing Scale. Success of the intervention was measured through questionnaires, focus groups and chart audit.

RESULTS

A multimodal intervention to overcome specific identified barriers (i.e. time, forgetfulness, and lack of knowledge) was implemented. There was a 10% increase in the use of at least one SQ. PTs reported increased knowledge and use of the SQ but reported time and lack of confidence as barriers to implementation.

CONCLUSION

It was concluded that SQ for CAT can be successfully implemented; however, PTs felt unprepared to use the screening results to evaluate persons with CAT and more extensive training is recommended to change this practice pattern.

Successful Management of Severe Low Back Pain with Ayurveda in Lumbar Spondylosis: A Case Report

Lumbar spondylosis is a common condition that is quite prevalent, affecting 57% of Indian men. Ayurveda, an indigenous medical system, is highly efficient in treating this ailment when it is in a mild to moderate state. This case report aims to provide a detailed account of a successfully managed case of lumbar spondylosis characterized by severe lumbar pain. A 59-year-old man, who has been suffering from lumbar spondylosis for the last 8 years, was presented with complaints of severe to moderate low back pain, disability, and pain in both legs. According to Ayurvedic principles, the condition was diagnosed as "Katigraha," and a nine-day treatment plan, including three Niruha Basti consecutively, followed by one Anuvasan Basti with the use of Ayurvedic medications was suggested. The lumbar pain severity fell from 8 to 2 points, while the leg pain decreased from 7 to 1 point. The Oswestry Low Back Disability Index (ODI) showed a significant reduction, from 49 to 18. The flexion and extension range of motion grew from 1 to 3 cm, and from 1 to 2 cm, respectively. The case study indicates a reduction in severe low back pain, but further investigation is required to determine the underlying mechanisms.

Hypertension-Mediated Organ Damage in Relation to Severity of Chronic Low Back Pain in Hypertensive Patients

INTRODUCTION

Chronic pain triggers a stress response, which results in increased blood pressure (BP). We investigated whether chronic low back pain (cLBP) in hypertensive patients is associated with an increased risk of hypertension-related organ damage.

METHODS

We studied 85 consecutive hypertensive patients with a median age of 62 years (55-67), who suffered from cLBP, the severity of which was evaluated according to the Oswestry Disability Index (ODI). Patients underwent transthoracic echocardiography, arterial ultrasonography and vascular tonometry. We assessed carotid artery atherosclerotic plaques, along with carotid-femoral pulse wave velocity (cf-PWV) and left ventricular mass index (LVMI).

RESULTS

An equal to or higher than median (16 points) ODI score in 48 subjects (56.5%) was associated with the presence of carotid artery plaques (p = 0.014). In multivariate analysis, after adjusting for covariates, the presence of carotid artery plaques remained independently associated with an ODI score equal to or higher than the median (OR, 3.71; 95% CI, 1.04-13.25; p = 0.044). None of the other analyzed parameters of hypertension-related organ damage demonstrated a significant relationship with the ODI score.

CONCLUSIONS

We observed that more severe cLBP is associated with a higher prevalence of carotid artery atherosclerotic plaques among hypertensive patients.

Efficacy of Self-Natural Posture Exercise (SNPE) programs on chronic low back pain: A randomized controlled feasibility trial with waitlist control

BACKGROUND

Low back pain (LBP) is a significant source of disability and decreased quality of life. The Self-Natural Posture Exercise (SNPE) intervention can be used effectively in many cases, but feasibility and impact has not been fully explored.

OBJECTIVE

The current study explores the feasibility and efficacy of face-to-face (FtF) and virtual (Vir) SNPE programs on chronic low back pain.

METHODS

This is a randomized single-blinded waitlist control study with 10 participants in the FtF group (age 45.8 ± 2.89) and 9 in the Vir group (age 52.2 ± 2.3). Participants had low to moderate low back pain for > 3 months. Those who would eventually become the Vir group served initially as a waitlist control (Con) group. The FtF group received 12 weeks of in-person exercise training sessions conducted and the Vir group received weekly recorded training videos created by and featuring the same instructor. Measured outcomes included feasibility assessed by rate of retention and rate of attendance, level of low back pain (Oswestry Disability Index, Visual Analogue Scale), quality of life (36-Item Short Form Health Survey 1.0), muscular pressure pain threshold, and muscle tone. Analysis was done via repeated measures ANOVA and Wilcoxon tests.

RESULTS

Rates of retention were 80% in the FtF group and 78% in the Vir group. Attendance rates were 88% in the FtF group and 60% in the Vir group. ODI, VAS, and some SF-36 domains improved in both the FtF and Vir groups. Overall, the FtF group improved in more domains and by a larger degree than the Vir group and both groups improved relative to Con.

CONCLUSION

A 12-week SNPE program, done virtually or in person, shows promise in improving ODI, VAS, and some SF-36 domains. FtF appears to be more effective. Future studies would benefit from sampling a larger and more diverse population.

The association of physical activity and sedentary behaviour with low back pain disability trajectories: A prospective cohort study

BACKGROUND

Multiple factors influence the recovery process of low back pain (LBP). The identification and increased knowledge of risk factors might contribute to a better understanding of the course of LBP.

OBJECTIVES

To investigate the association of habitual physical activity (PA) and sedentary behaviour (SB), measured at baseline, with disability trajectories in adults with LBP.

METHODS

A prospective cohort study where habitual PA levels were measured using the Short QUestionnaire to ASsess Health enhancing physical activity (SQUASH), SB was calculated as average sedentary hours per day, and LBP disability using the Oswestry Disability Index (ODI). Participants completed the questionnaires at one and a half, three, six, and twelve months. Linear mixed models were estimated to describe the association of habitual PA levels SB measured at baseline with disability trajectories. Other predictors were gender, education level, age, pain, number of previous episodes of LBP, and duration of LBP.

RESULTS

Habitual SB measured at baseline in adults (n = 347) with LBP were not associated with disability trajectories. For PA, participants with one metabolic equivalent of task (MET) hour per day above average recovered 0.04 [95% CI 0.004 to 0.076] points on the ODI per month faster than participants with an average amount of MET hours per day.

CONCLUSIONS

Habitual SB was not associated with LBP disability trajectories over a one-year follow-up. High levels of habitual PA at baseline were associated with improved recovery in LBP disability trajectory, but the finding is not clinically relevant.

How to Evaluate the Efficacy of Manipulations in Spine Disorders-A Comprehensive Review of New and Traditional Outcome Measures

Spine pain (SP) is the most common musculoskeletal disorder that causes transitional forms of motor disability. Considering its affordability and safety, manipulative therapy (MT) stands as one of the primary therapeutic approaches for SP and the related dysfunctional consequences. However, it is still difficult to assess and quantify the results of this treatment since there is a lack of objective evaluation tools in the available scientific literature. Thus, the purpose of this comprehensive review is to summarize the main outcomes used to evaluate the effectiveness of spine manipulations, focusing on their strengths and weaknesses. An extensive review of the PubMed, Cochrane, and Embase databases was performed to identify the literature of the last ten years regarding MT and the related assessment tools. A total of 12 studies met the inclusion criteria. The analyzed literature indicates that a wide range of outcome measures have been used to assess the effectiveness of spine MT. Pain is the main aspect to be investigated but it remains difficult to elucidate since it is strongly linked to various dimensions such as self-perception and psychological aspects. Therefore, it seems necessary to include new tools for evaluating the effects of spine MT, with the aim of exploiting new technologies and taking into consideration the SP biomechanical and biopsychosocial aspects.

Comparable rates of lumbar disc degeneration at long-term following adolescent idiopathic scoliosis spinal fusion extended to L3 or L4: systematic review and meta-analysis

PURPOSE

Surgical treatment of adolescent idiopathic scoliosis (AIS) requires a careful choice of fusion levels. The usual recommendation for the selection of the lowest instrumented vertebra (LIV) for double major or thoracolumbar/lumbar (TL/L) curves falls on L3 or L4. The aim of the present study is to assess if the spinal fusion with LIV selection of L3 or L4 in AIS patients has a clinical or radiological impact in terms of degenerative disc disease (DDD) in distal unfused segments at long-term follow-up.

METHODS

A systematic search of electronic databases from eligible articles was conducted. Only studies regarding long-term follow-up of AIS patients treated with spinal fusion were included. Clinical and radiographic outcomes were extracted and summarized. Meta-analysis on long-term follow-up MRI studies was performed. p value < 0.05 was considered significant.

RESULTS

Fourteen studies were included, for a total of 1264 patients. Clinical assessment of included patients showed a slight tendency to have worse clinical outcomes if spinal fusion is extended to L4 rather than L3. Despite that, meta-analysis could not be performed on clinical parameters because of heterogeneity of evaluated PROMs in included studies. Magnetic resonance imaging (MRI) evaluation at long-term follow-up showed no significant difference in terms of disc degeneration rate at overall meta-analysis (p = 0.916) between patients fused to L3 and L4.

CONCLUSION

The LIV selection of L3 rather than L4, according to current literature, does not prevent disc degeneration in distal unfused segments over the long term. Long-term studies of patients treated with contemporary spinal instrumentation are needed.

Psychometric Properties of Chosen Scales Evaluating Disability in Low Back Pain-Narrative Review

Low back pain (LBP) is one of the most common disabling conditions. This disability significantly reduces the quality of life of LBP patients. This article reviews the most common and well-known measures currently used to assess disability in LBP, such as the Oswestry Disability Index (ODI), the Roland-Morris Disability Questionnaire (RMDQ), the Quebec Back Pain Disability Scale (QBPDS), the Low Back Outcome Score (LBOS), and the Low Back Pain Rating Scale (LBPRS). To reliably evaluate questionnaires and other measurement methods, there are parameters known as psychometric properties, which consist primarily of the validity, reliability and sensitivity. These methods are based on a multi-item questionnaire assessing physical functioning that is completed independently by the patient. They can be used to assess the disability associated with many conditions. All are specific to LBP, and their psychometric properties have been tested on a relevant population of patients with the condition and published in peer-reviewed publications.

Group Physical Therapy Programs for Military Members With Musculoskeletal Disorders: A Pragmatic Randomized Controlled Trial

OBJECTIVE: To compare the effects of personalized, supervised group-based programs (ie, group physical therapy programs) and usual one-on-one physical therapy care (ie, usual physical therapy care) on disability for military personnel suffering from low back pain, rotator cuff-related shoulder pain, patellofemoral pain syndrome, or lateral ankle sprain. Secondary outcomes were pain severity, pain-related fear, health-related quality of life, and patients' satisfaction with their condition and care. DESIGN: Non-inferiority pragmatic randomized clinical trial. METHODS: One hundred twenty military personnel from the Canadian Armed Forces, experiencing 1 of 4 targeted musculoskeletal disorders, were consecutively recruited and randomly assigned to group physical therapy programs or usual physical therapy care. Disability, pain severity, pain-related fear, and health-related quality-of-life outcomes were measured at 6, 12, and 26 weeks after baseline. Satisfaction with treatment was evaluated at the end of the intervention. Intention-to-treat analyses using linear mixed models with random effects were used to compare the effects of interventions. Chi-square tests were used to compare satisfaction. RESULTS: There were no significant Time × Group interactions for any of the primary and secondary outcomes (Time × Group: P>.67). Satisfaction with treatment also did not differ between groups (P>.05). Statistically significant and clinically important improvements were observed in both groups for all outcomes after 12 weeks (Time effect: P<.01), except for health-related quality of life (P = .13). CONCLUSION: Group physical therapy programs were not inferior to usual physical therapy care for managing pain, functional capacity, and patients' satisfaction with care of military personnel presenting with various musculoskeletal disorders. Both interventions led to clinical and statistical improvement in pain and function in the mid and long term. Group physical therapy could be an effective strategy to enhance access to care.

Sexual functioning is not, but psychological burden is predictive for receiving help in pelvic physical therapy practice: A cross-sectional study

Background

Pelvic floor complaints are common among women and often accompanied by sexual dysfunction and psychological burden. They are also associated with pregnancy and childbirth. However, not all women with these complaints receive help in pelvic physical therapy practice. This study explored if pregnancy, parity, pelvic floor complaints, sexual functioning, and psychological burden are predictive of receiving help in pelvic physical therapy practice.

Methods

In a cross-sectional exploratory design, women completed an online survey about pelvic floor complaints, sexual function, and psychological burden. Binary logistic analysis was used to analyze the predictive value of the above-mentioned factors.

Results

Data from 542 participants were analyzed. Pregnancy and parity, PFC severity, psychological burden, and the interaction between pelvic floor complaints and psychological burden were significant predictors of receiving help. Against expectations, sexual functioning was not predictive of receiving help.

Conclusions

Women's psychological burden is an important factor in determining if or when women receive help in PPT practice. More research is needed to unravel the role of sexual functioning in the context of pelvic floor complaints and women's psychological burden. More insight into this area of expertise could possibly improve and enhance pelvic health care for women with pelvic floor complaints.

Combined Ultrasound and Fluoroscopy versus Ultrasound versus Fluoroscopy-Guided Caudal Epidural Steroid Injection for the Treatment of Unilateral Lower Lumbar Radicular Pain: A Retrospective Comparative Study

Background and Objectives: This study aimed to evaluate the mid-term effectiveness and safety of a combined ultrasound (US) and fluoroscopy (FL)-guided approach in comparison to US-guided and FL-guided caudal epidural steroid injections (CESI) for treating unilateral lower lumbar radicular pain. Materials and Methods: A total of 154 patients who underwent CESI between 2018 and 2022 were included. Patients were categorized into three groups based on the guidance method: combined US and FL (n = 51), US-guided (n = 51), and FL-guided (n = 52). The study design was retrospective case-controlled, utilizing patient charts and standardized forms to assess clinical outcomes, adverse events, complications during the procedures. Results: In all groups, Oswestry Disability Index and Verbal Numeric Scale scores improved at 1, 3, and 6 months after the last injection, with no significant differences between groups (p < 0.05). The treatment success rate at all time points was also similar among the groups. Logistic regression analysis showed that injection method, cause, sex, age, number of injections, and pain duration did not independently predict treatment success. Blood was aspirated before injection in 2% (n = 1), 13.5% (n = 7), and 4% (n = 2) of patients in the combined US and FL groups, FL-guided groups, and US-guided groups, respectively. Intravascular contrast spread was detected in one patient in the combined method groups and seven in the FL-guided groups. Conclusions: When comparing pain reduction and functional improvement, there was no significant difference between the three methods. The combined method took less time compared to using FL alone. The combined approach also showed a lower occurrence of intravascular injection compared to using FL alone. Moreover, blood vessels at the injection site can be identified with an ultrasound using the combined method. Given these advantages, it might be advisable to prioritize the combined US- and FL-guided therapy when administering CESI for patients with unilateral lumbar radicular pain.

Advantages of unilateral percutaneous kyphoplasty for osteoporotic vertebral compression fractures-a systematic review and meta-analysis

Data from English randomized controlled trials comparing unilateral versus bilateral PKP for the treatment of OVCFs were retrieved and analyzed, and the results showed that unilateral PKP is a better choice for the treatment of patients with OVCFs, which will provide a reliable clinical rationale for the treatment of OVCFs.

PURPOSE

To investigate the advantages of unilateral percutaneous kyphoplasty (PKP) for the treatment of osteoporotic vertebral compression fractures(OVCFs).

METHODS

The systematic evaluation program met all program requirements (CRD 42023422383) by successfully passing the PROSPERO International Prospective Systematic Evaluation Registry. Researchers searched the references of English-language randomized controlled trials comparing unilateral and bilateral PKP for the treatment of osteoporotic vertebral compression fractures published between 2010 and 2023 and manually searched for known primary and review articles. The study statistically analyzed data from all the included literature, which primarily included time to surgery, visual pain score(VAS) and Oswestry disability index(ODI) at postoperative follow-up time points, polymethylmethacrylate (PMMA, bone cement) injection dose, cement leakage, radiation dose, and improvement in kyphotic angle.

RESULTS

This meta-analysis searched 416 articles published from 2010 to 2023 based on keywords, and 18 articles were finally included in this study. The results of the forest plot showed that unilateral PKP operative time, amount of bone cement used, and radiation dose to the patient were significantly reduced (p < 0.01, p < 0.01, and p < 0.01, respectively), and unilateral and bilateral PKP had comparable cement leakage (p = 0.49, 95% CI = 0.58-1.30), and there was no significant difference in the kyphotic angle between unilateral and bilateral PKP (p = 0.42, 95% CI =  - 2.29-0.96). During follow-up, there was no significant difference in pain relief between unilateral and bilateral PKP (p = 0.70, 95% CI =  - 0.09-0.06), nor was there a significant difference in ODI (p = 0.27, 95% CI =  - 0.35-1.24).

CONCLUSIONS

There is no difference in clinical efficacy between unilateral PKP and bilateral PKP, but unilateral PKP has a shorter operative time, a lower incidence of cement leakage, a lower amount of cement, and a lower radiation dose to the patient and operator. Unilateral PKP is a better option for patients with OVCFs.

Automatic Associations between Sexual Function Problems and Pursuing Help in Pelvic Physical Therapy Practice: The Psychometric Investigation of an Implicit Association Test

Not all women experiencing pelvic floor complaints and sexual function problems seek help in pelvic physical therapy practice. Decisions to seek help can result from explicit and implicit cognitive processes. Having found some explicit predictive factors for receiving help in this setting, this study examines possible complementary implicit associations between sexual function problems and pursuing help that might also be predictive. The Pursuing Help for Sexual Problems Implicit Association Test (PHSP-IAT) was specially developed for this purpose. The instrument's reliability and validity were evaluated. High reliability was found (Spearman's Rho = .95). Convergent and divergent validity analyses resulted in low and non-significant correlations between the PHSP-IAT and the chosen self-report measures. The PHSP-IAT was predictive for receiving help in pelvic physical therapy practice. Further research is necessary to determine the PHSP-IAT's validity and its predictive value in other healthcare settings.

The association of the STarT Back Screening Tool and type of leg pain with low back pain disability trajectories: a prospective cohort study

BACKGROUND

Multiple factors influence the recovery process of low back pain (LBP). The identification and increased knowledge of prognostic factors might contribute to a better understanding of the course of LBP. The purpose of this study is to investigate the association of the STarT Back Screening Tool (SBST) risk score and the type of leg pain (non-radiating LBP, referred non-radicular, and radicular radiating leg pain) with the disability trajectory (at baseline, the slope, and recovery at one year) in adults with low back pain.

METHODS

This is a prospective cohort study in 347 patients with low back pain who sought physiotherapy care at three primary care practices in the Netherlands. Linear mixed models were estimated to describe the association of the SBST risk score and the type of leg pain with disability at baseline, the slope in the disability trajectory, and at twelve months follow-up.

RESULTS

A medium/high risk score on the SBST is associated with higher baseline disability scores on the Oswestry Disability Index (ODI), faster initial recovery, and still a higher disability ODI score at 12 months follow-up. Non-radicular referred and radicular radiating leg pain were associated with worse baseline disability ODI scores in LBP. This association was not present for the initial recovery or at the 12 months follow-up.

CONCLUSION

The SBST is associated with the LBP recovery trajectory. The SBST might be a useful tool to predict the disability trajectory in a heterogeneous group of people with low back pain in primary care and might, therefore, be recommended in future clinical practice guidelines. The type of leg pain was not associated with the recovery trajectory of LBP. Future research might focus on evaluating different types of leg pain.

Worse Preoperative Disability is Predictive of Improvement in Disability After Complex Adult Spinal Deformity Surgery

STUDY DESIGN

Retrospective Cohort Study.

OBJECTIVES

Few previous studies have examined the relationship between preoperative disability and patient outcomes after complex adult spinal deformity surgery. In this study, we hypothesized that patients with worse preoperative disability would be more likely achieve a clinically significant improvement in their symptoms after surgery.

METHODS

Demographics, comorbidities, surgical data, and health related survey results were analyzed from a consecutive series of adults (≥18 years old) who underwent spinal deformity correction, instrumentation, and fusion. Patients included had 6 or more levels fused and their surgery performed at single institution between 2015 and 2018 with minimum 2 year follow up.

RESULTS

A total of 108 patients met inclusion criteria. Bivariate analysis demonstrated the following as having a greater probability of reaching minimum clinically important difference (MCID) at 2 years postoperatively: >50th percentile Oswestry Disability Index (ODI) score (ODI >36), cardiac comorbidities, and use of pelvic fixation, pedicle subtraction osteotomy, and transforaminal lumbar interbody fusion. Conversely, baseline Scoliosis research society score (SRS) >50th percentile (SRS ≥62) and use of vertebral column resection (VCR) were significant predictors of not reaching MCID at 2 years. On logistic regression analysis, >50th percentile ODI score (ODI >36) was identified as the only independent predictor of achieving MCID.

CONCLUSIONS

Patients with greater disability, independent of other preoperative or surgical factors, are more likely to have clinically significant improvement in their daily functioning after complex deformity surgery. For patients who undergo surgical intervention for severe or progressive deformity, including VCR, MCID might be an ineffective outcome measure.

Challenges of Measuring Self-Reported Exposure to Occupational Biomechanical Risk Factors Amongst People with Low Literacy Engaged in Manual Labour: Findings from a Cross-Cultural Adaptation and Psychometric Investigation in an African Population with Chronic Low Back Pain

PURPOSE

Occupational biomechanical factors are implicated in the aetiology and progression of low back pain (LBP). This study cross-culturally adapted and psychometrically investigated the Occupational Risk Factor Questionnaire (ORFQ) in a low literate Nigerian Igbo population with chronic LBP.

METHODS

Forward and back translation of the original ORFQ by clinical and non-clinical translators was followed by an expert committee review. The adapted ORFQ was pre-tested amongst rural Nigerian adults with chronic LBP using cognitive think-aloud interviewing. Internal consistency (Cronbach's alpha) and test-retest reliability (unweighted and linear weighted k statistic for item-by-item agreement, and intra-class correlation coefficient-ICC) were investigated amongst 50 rural and urban Nigerian dwellers with chronic LBP. Spearman's correlation and regression analyses were conducted with the Igbo-ORFQ, and measures of disability [World Health Organisation Disability Assessment Schedule (WHODAS 2.0), Roland Morris Disability Questionnaire (RMDQ), Back performance scale (BPS)], pain intensity [Eleven-point box scale (BS-11)] and social support [Multidimensional Scale of Perceived Social Support (MSPSS)], to test construct validity with 200 rural Nigerian dwellers with chronic LBP.

RESULTS

Cross-cultural adaptation highlighted difficulty conceptualising and concretising exposure to biomechanical risk factors. Item-by-item agreement, internal consistency (α = 0.84) and intraclass correlation coefficient (ICC = 0.83) were good. Some unexpected direction of associations between the biomechanical components of the Igbo-ORFQ, and disability, pain intensity, and social support prohibits establishment of construct validity.

CONCLUSION

Prospective studies comparing the Igbo-ORFQ to other measures of exposure to occupational biomechanical risk factors are required to establish the construct validity of the Igbo-ORFQ.

The effect of minimally invasive sacroiliac joint fusion compared to sham operation: a double-blind randomized placebo-controlled trial

Background

Minimally invasive fusion of the sacroiliac joint as treatment for low back pain may reduce pain and improve function compared to non-operative treatment, although clear evidence is lacking. The aim of this trial was to evaluate the effect of minimally invasive sacroiliac joint fusion compared to sham surgery on sacroiliac joint pain reduction.

Methods

In this double-blind randomized sham surgery-controlled trial patients with clinical diagnosis of sacroiliac joint pain confirmed with sacroiliac joint injection were included at two university hospitals in Sweden and Norway. Patients were randomized by the operating surgeon at each site to minimally invasive sacroiliac joint fusion or sham surgery. The primary endpoint was group difference in sacroiliac joint pain on the operated side at six months postoperatively, measured by the Numeric Rating Scale (0-10). Un-blinding and primary analysis were performed when all patients had completed six months follow-up. The trial is closed for new participants and was registered at clinicaltrials.gov: NCT03507049.

Findings

Between September 1st, 2018 and October 22nd, 2021, 63 patients were randomized, 32 to the surgical group, 31 to the sham group. Mean age was 45 years (range 26-63) and 59 of 63 (94%) patients were female. The mean reduction in the operated sacroiliac joint from baseline to six months postoperative was 2.6 Numeric Rating Scale points in the surgical group and 1.7 points in the sham group (mean between groups difference -1.0 points; 95% CI, -2.2 to 0.3; p = 0.13).

Interpretation

This double-blind randomized controlled trial could not prove that minimally invasive fusion of the sacroiliac joint was superior to sham surgery at six months postoperative.

Trajectories of Physical Function and Disability Over 12 Months in Older Adults With Chronic Low Back Pain

BACKGROUND AND PURPOSE

Understanding prognosis is critical for clinical care and health policy initiatives. The purpose of this study was to determine whether distinct prognostic trajectories of physical function and disability exist in a cohort of 245 community-dwelling older adults with chronic low back pain (LBP), and to characterize the demographic, health, and pain-related profiles of each trajectory subgroup.

METHODS

All participants underwent standard clinic examinations at baseline, 3 months, 6 months, and 12 months. At each time point, the Late Life Function & Disability Instrument (LLFDI) was used to measure general physical function (LLFDI Function) and disability (LLFDI Disability-Limitation); the Quebec LBP Disability Questionnaire was used to measure disability due to pain. Growth mixture modeling (GMM) was performed on each outcome to identify distinct trajectory classes/subgroups; baseline demographic (eg, age and sex), health (eg, comorbidities, depressive symptoms, and physical activity level), and pain-related (eg, LBP intensity, pain-related fear, and pain catastrophizing) characteristic profiles were compared across subgroups.

RESULTS

GMM statistics revealed an optimal number of 3 to 4 trajectory subgroups, depending on the outcome examined. Subgroups differed across demographic, health, and pain-related characteristics; the classes with the most favorable prognoses had consistent profile patterns: fewer depressive symptoms, fewer comorbidities, higher physical activity levels, lower LBP intensities, less pain-related fear, and less pain catastrophizing.

CONCLUSION

Our findings indicate that several distinct trajectory subgroups exist that would have been masked by observing mean cohort change alone. Furthermore, subgroup characteristic profiles may help clinicians identify likely prognostic trajectories for their patients. Future research should focus on identifying modifiable risk factors that best predict group membership, and tailoring interventions to mitigate the risk of poor prognosis.

Pain Scales: What Are They and What Do They Mean

PURPOSE OF REVIEW

It is essential to have validated and reliable pain measurement tools that cover a wide range of areas and are tailored to individual patients to ensure effective pain management. The main objective of this review is to provide comprehensive information on commonly used pain scales and questionnaires, including their usefulness, intended purpose, applicability to different patient populations, and associated advantages and disadvantages.

RECENT FINDINGS

Acute pain questionnaires typically focus on measuring the severity of pain and the extent of relief achieved through interventions. Chronic pain questionnaires evaluate additional aspects such as pain-related functional limitations, psychological distress, and psychological well-being. The selection of an appropriate pain scale depends on the specific assessment objectives. Additionally, each pain scale has its strengths and limitations. Understanding the differences among these pain scales is essential for selecting the most appropriate tool tailored to individual patient needs in different settings.

CONCLUSION

Medical professionals encounter challenges in accurately assessing pain. Physicians must be familiar with the different pain scales and their applicability to specific patient population.

Combined Rehabilitation with Alpha Lipoic Acid, Acetyl-L-Carnitine, Resveratrol, and Cholecalciferolin Discogenic Sciatica in Young People: A Randomized Clinical Trial

Background and Objectives: In the Western world, back pain and sciatica are among the main causes of disability and absence from work with significant personal, social, and economic costs. This prospective observational study aims to evaluate the effectiveness of a rehabilitation program combined with the administration of Alpha Lipoic Acid, Acetyl-L-Carnitine, Resveratrol, and Cholecalciferol in the treatment of sciatica due to herniated discs in young patients in terms of pain resolution, postural alterations, taking painkillers, and quality of life. Materials and Methods: A prospective observational study was conducted on 128 patients with sciatica. We divided the sample into 3 groups: the Combo group, which received a combination of rehabilitation protocol and daily therapy with 600 mg Alpha Lipoic Acid, 1000 mg Acetyl-L-Carnitine, 50 mg Resveratrol, and 800 UI Cholecalciferol for 30 days; the Reha group, which received only a rehabilitation protocol; and the Supplement group, which received only oral supplementation with 600 mg Alpha Lipoic Acid, 1000 mg Acetyl-L-Carnitine, 50 mg Resveratrol, and 800 UI Cholecalciferol. Clinical assessments were made at the time of recruitment (T0), 30 days after the start of treatment (T1), and 60 days after the end of treatment (T2). The rating scales were as follows: the Numeric Rating Scale (NRS); the Oswestry Disability Questionnaire (ODQ); and the 36-item Short Form Health Survey (SF-36). All patients also underwent an instrumental stabilometric evaluation. Results: At T1, the Combo group showed statistically superior results compared to the other groups for pain (p < 0.05), disability (p < 0.05), and quality of life (p < 0.05). At T2, the Combo group showed statistically superior results compared to the other groups only for pain (p < 0.05) and quality of life (p < 0.05). From the analysis of the stabilometric evaluation data, we only observed a statistically significant improvement at T2 in the Combo group for the average X (p < 0.05) compared to the other groups. Conclusions: The combined treatment of rehabilitation and supplements with anti-inflammatory, pain-relieving, and antioxidant action is effective in the treatment of sciatica and can be useful in improving postural stability.

Lateral Lumbar Spinal Stenosis: Associations With the Oswestry Disability Index, Visual Analogue Scale, and Magnetic Resonance Imaging

Introduction Degenerative lumbar spinal stenosis is a communal problem in the sixth decade of life involving L4/L5 and L5/S1 levels. Lateral spinal stenosis is often underestimated because of no established relationship between the clinical symptoms and MRI findings. We conducted a study to establish an association between the degree of anatomical lateral stenosis, posterior disc height, and disc degeneration from MRI with the daily disability and pain severity for lateral lumbar spinal stenosis. Methods This was a cross-sectional study involving 121 patients with distinct clinical symptoms of lateral lumbar spinal stenosis evaluated from February 2018 to December 2019. The clinical data were evaluated using the Oswestry Disability Index (ODI) and Visual Analogue Scale (VAS), while magnetic resonance imaging (MRI) was assessed qualitatively for the anatomical gradation of lateral spinal stenosis, the magnitude of posterior disc height, and the extent of disc degeneration. Statistical analysis for the correlation between posterior disc height and ODI and VAS scores was evaluated using Pearson's correlation test via SPSS version 23.0 (IBM Inc., Armonk, New York), and the association between the extent of lateral stenosis and disc degeneration on MRI with ODI and VAS scores was determined by the Fisher Exact Test via STATA version 14.0 (StataCorp LLC, College Station, Texas). The association was considered statistically significant with a P-value of less than 0.05. Results The analysis of 121 patients showed the mean age of the patients was 58.7 ± 7.1 years old. The number of female patients was higher compared to male patients, 52.9% and 47.1%, respectively. 97.5% of the patients were married or cohabiting, and 76.0% had an abnormal body mass index. The mean score of ODI and VAS was 62.2 ± 10.7% and 79.3 ± 8.6 respectively. 49.6% of the patient presented with a crippling disability with ODI assessment, while 59.5% presented with high pain intensity with VAS assessment. MRI assessment of anatomical grading lateral stenosis of L4/L5 level revealed that 45.5% of the patients had grade 2 lateral recess stenosis, 63.6% had grade 2 foraminal stenosis, and 44.6% had extraforaminal stenosis. L5/S1 level analysis showed that 43.0% had grade 2 lateral recess stenosis, 62.0% had grade 2 foraminal stenosis, and 29.8% had extraforaminal stenosis. 64.5% of patients had grade 4 disc degeneration of L4/L5 with mean posterior disc height of 7.0mm ±1.7mm while 59.5% had grade 4 disc degeneration of L5/S1 with mean posterior disc height of 6.3mm ±1.8mm. However, no statistically significant association between clinical symptoms and MRI findings was found.  Conclusions There was no significant association between the clinical symptoms of pain and disability and the MRI findings for the anatomical gradation of lateral spinal stenosis, the magnitude of posterior disc height, and the extent of disc degeneration. A comprehensive clinical evaluation remains essential for an accurate diagnosis, emphasizing the necessity of appropriately correlating MRI findings with their clinical significance.

Effect of spinal-pelvic sagittal balance on the clinical outcomes after lumbar fusion surgery

BACKGROUND

Spinal-pelvic sagittal balance is important for maintaining energy-efficient posture in normal and diseased states.Few reports to date have evaluated the effect of spinal-pelvic sagittal balance on clinical outcomes after lumbar interbody fusion in patients with lumbar degenerative diseases (LDD).

METHODS

A total of 303 patients treated with posterior lumbar interbody fusion surgery for lumbar degenerative disease from January 2012 to December 2019 were enrolled in this retrospective study according to the inclusion criteria. Preoperative and postoperative spinal-pelvic sagittal parameters including pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS) and lumbar lordosis (LL) of the patients were evaluated and compared. 163 patients whose postoperative PI-LL ≤ 10° were divided into the spinal-pelvic match group (Group M), while 140 patients were divided into the spinal-pelvic mismatch group (Group MM). Preoperative and postoperative Oswestry Disability Index (ODI) and Visual Analog Scale (VAS) for back pain of both groups were compared.

RESULTS

There was no significant difference between the two groups in demographic and surgical data, except for blood loss in surgery. LL, PI, PT and SS of the patients at final follow-up were all statistically different from the preoperative values in the two groups(P < 0.05). There was no significant difference in LL, PI, PT and SS between the two groups before surgery. At the final follow-up, LL, PI and PT differed significantly between the two groups(P < 0.05). Compared with the preoperative results, ODI and VAS of low back in both groups decreased significantly at the final follow-up (P < 0.05). Significant differences in VAS and ODI were found between the two groups at the final follow-up (P < 0.05). The improvement rates of VAS and ODI of Group M are both significantly higher than Group MM. Regression analysis showed that age and spinal-pelvic match had significant effects on the improvement of patients' low back pain at the final follow-up.

CONCLUSIONS

lumbar interbody fusion can significantly improve the prognosis of patients with LDD. In terms of outcomes with an average follow-up time of more than 2 years, the spinal-pelvic match has a positive effect on patients' quality of life and the release of low back pain.

Evaluation of the efficacy, in terms of pain and disability, of a functional restoration programme in patients with chronic low back pain according to the presence of Modic 1 discopathy

OBJECTIVES

Modic type 1 disc disease (MD1) appears to be related to severe Chronic Low Back Pain (CLBP). Functional Restoration Programmes (FRP) recommended in CLBP may not be suitable for patients with MD1. The main objective was to evaluate the effectiveness of a FRP, on the perceived incapacity and the pain intensity, in patients with non-specific CLBP according to the presence of MD1.

METHODS

We performed a single-centre retrospective cohort study in which 271 patients were included. After one month in the FRP, this programme was considered "successful" if the pain visual analog scale had decreased by at least 20/100 millimetres and if the score of the French version of the Roland-Morris disability questionnaire had decreased by at least 4/24 points.

RESULTS

The 271 patients had an average age of 43.2 (8.0) years and 58.3% were women. Out of our entire population, 128 (47.2%) patients were considered successful, and 51 (18.8%) patients had MD1. In patients without MD1, there was 49.1% success while this rate was 39.2% in those with MD1, but this difference was not statistically significant.

CONCLUSIONS

We found no significant difference in the combination of pain and perceived disability after one month of a FRP in patients with CLBP without MD1 compared to those with CLBP with MD1. It therefore seems legitimate to offer FRP-type rehabilitation in patients with non-specific CLBP with MD1.

Functional scales used by the Egyptian physiotherapist in the assessment of low back pain: a cross-sectional study

Background

The use of functional scales is crucial for the management of low back pain. Numerous pertinent outcome measures are available; however, it is unknown how much use Egyptian physiotherapists make of these scales and measurements when diagnosing and treating patients with low back pain.

Aim

The purpose of this study was to investigate how Egyptian physical therapists working in Egypt used functional outcome measures and scales when treating low back pain.

Design and methods

A cross-section study used an online web-based survey which was accessible to all Egyptian physiotherapists practicing in Egypt.

Results

334 Egyptian physical therapists participated in this study. The use of the pain disability index and back pain functional scale represents the highest frequency of (always/often) of 56.3% and 53.6% respectively, whereas the use of the Quebec Back Pain Disability Scale or the Roland-Morris Disability Questionnaire represents the highest frequency of (rarely/never) 45.8% and 53%, respectively. There was no significant association between gender, years of experience, educational level, and work setting with the use of functional outcome measures (p > 0.05).

Conclusion

Egyptian physiotherapists more usually utilize the pain disability index and back pain functional scale (PDI and BPFS), when evaluating their patients with low back pain, although they did not commonly use the Roland-Morris Disability Questionnaire or the Quebec Back Pain Disability Scale

A novel physical functioning test to complement subjective questionnaires in chronic low back pain assessments

BACKGROUND CONTEXT

Lifting disability commonly affects patients with chronic low back pain (CLBP) and may not correlate with the existing lifting-related physical assessment tests, such as the loaded forward reach (LFR) test.

PURPOSE

The Lift and Place (LAP) test was developed to assess lifting disability in CLBP based on known risk factors. The LAP test was compared with established physical assessment test, including the LFR test and self-reported disability questionnaires.

STUDY DESIGN/SETTING

This cross-sectional study measured self-reported disability questionnaires along with LAP and other physical assessment test results PATIENT SAMPLE: Eighty three CLBP and 82 asymptomatic participants aged 18 to 55 with normal BMI according to WHO classification.

OUTCOME MEASURES

Oswestry disability index (ODI), Roland-Morris disability questionnaire (RMDQ), Numerical Pain Rating Scale, Trunk Extensor Endurance test, 5 Repetition Sit-To-Stand test, LAP and LFR test.

METHODS

Physical assessment test scores were compared between the two groups. The correlation of assessment test scores with ODI and RMDQ in patients with CLBP was calculated. Receiver operating characteristic (ROC) curve analysis was performed to calculate the area under the curve (AUC) of each assessment tests. Assessment tests, ODI, and RMDQ were measured twice for CLBP patients on separate days to calculate the test-retest intraclass correlation (ICC) reliability. Two researchers scored the assessment tests independently to calculate the inter-rater ICC.

RESULTS

Patients with CLBP were slower in the LAP test (CLBP vs asymptomatic: 21.6±4.9 s vs 18.6±3.6 s) and had shorter reach in the LFR test (CLBP vs asymptomatic: 33.6±6.0 cm vs 36.3±6.6 cm). The LAP was correlated with both ODI (r=0.418) and RMDQ (r=0.390), while the LFR was not. In the ROC analysis, the LAP and LFR bore AUCs of 0.685 and 0.379, respectively. Their test-retest ICCs were 0.913 and 0.858, and their inter-rater ICCs were 0.997 and 0.969, respectively.

CONCLUSIONS

The LAP test demonstrated higher reliability and significant correlation with the ODI and RMDQ, indicating its potential as performance assessment for lifting disability in CLBP. Further studies should investigate the use of LAP and other physical assessments for rapid CLBP screening.

Systemically Acting Diclofenac Sodium Patch for Control of Low Back Pain: A Randomized, Double-Blind, Placebo-Controlled Study in Japan

INTRODUCTION

Nonsteroidal antiinflammatory drugs (NSAIDs) are commonly used for pain disorders such as low back pain and exist in multiple formulations; however, no systemically acting transdermal formulations are available for low back pain. Transdermal formulations can be safely administered even to patients with trouble swallowing or at risk of aspiration, and without regard to the effect of food on drug absorption. Unlike locally acting formulations, systemically acting transdermal formulations need not be applied at the target site, so dosing is simple and the burden is not on one area of the skin. A patch with the systemically acting NSAID diclofenac sodium is approved in Japan for treatment of cancer-related pain, and we hypothesized that it would be useful for controlling low back pain.

METHODS

This randomized, double-blind, placebo-controlled study aimed to evaluate the efficacy and safety of diclofenac sodium patch in Japanese patients with low back pain. Eligible patients were randomized to receive diclofenac sodium patch 75 mg or 150 mg or placebo once daily for 2 weeks. The primary endpoint was pain intensity assessed on a visual analog scale (VAS).

RESULTS

Primary analysis of the primary endpoint showed that both doses of the diclofenac sodium patch (150 mg and 75 mg) were superior to placebo in terms of absolute change from baseline in mean 3-day VAS score after 2 weeks' treatment; the mean difference between the active and placebo treatments in this variable was -5.67 [95% confidence interval (CI) -9.34 to -2.00] mm in the 150 mg group and -5.68 (95% CI -9.34 to -2.01) mm in the 75 mg group. Most adverse events were mild. No serious adverse events occurred.

CONCLUSION

In Japanese patients, diclofenac sodium patch is effective for the relief of low back pain and is well tolerated.

Pain, smartphone overuse and stress in physiotherapy university students: An observational cross-sectional study

BACKGROUND

There is a high prevalence of musculoskeletal pain and stress levels in university students in the health area. The current study aimed to evaluate the prevalence of pain in the cervical region, lumbar spine, and upper and lower limbs in university students in the final year of physiotherapy; and to determine the correlation between smartphone overuse, stress level, and musculoskeletal pain.

METHODS

This is observational cross-sectional study. Students completed an online questionnaire containing sociodemographic information, the Neck Disability Index (NDI), Nordic Musculoskeletal Questionnaire (NMQ), Smartphone Addiction Scale Short-version (SAS-SV), Job Stress Scale, and Oswestry Disability Questionnaire (ODI). The Biserial-point correlation test and Spearman correlationvtest was performed.

RESULTS

In total, 42 university students participated in the study. The results indicate a high prevalence of students with cervical pain (83.3%), lumbar pain (76.2%), shoulder (57.1%) and wrist (52.4%). Correlations were found in the comparison of the SAS-SV versus NDI (p < 0.001, R = 0.517) and neck pain (p = 0.020, R = 0.378). The stress scale versus pain in the upper back (p = 0.008, R = 0.348), elbow (p = 0.047, R = 0.347), wrist (p = 0.021, R = 0.406), and knee (p = 0.028, R = 0.323), pain in the wrist versus high scores in the SAS-SV (p = 0.021, R = 0.367), and also hours spent using the smartphone versus pain in the hip (total time: p = 0.003, R = 446; work: p = 0.041, R = 0.345; recreation: p = 0.045, R = 0.308).

CONCLUSION

There is a high prevalence of pain in the cervical and lumbar regions in university students in the final year of Physiotherapy. A correlation was found between neck disability, neck and upper back pain and overuse of the smartphone and stress.

Traditional Chinese Manual Therapy (Tuina) reshape the function of default mode network in patients with lumbar disc herniation

Purpose

Investigating the changes of regional homogeneity (ReHo) values and both static and dynamic functional connectivity (FC) before and after Traditional Chinese Manual Therapy (Tuina) in patients with lumbar disk herniation (LDH) through resting-state functional magnetic resonance imaging (RS-fMRI). Based on this, we observe the effect of Tuina on the above abnormal changes.

Methods

Patients with LDH (n = 27) and healthy controls (HCs) (n = 28) were recruited. The functional magnetic resonance imaging (fMRI) scanning was performed two times in LDH patients, before Tuina (time point 1, LDH-pre) and after the sixth Tuina (time point 2, LDH-pos). And for one time in HCs which received no intervention. The ReHo values were compared between LDH-pre and HCs. The significant clusters detected by ReHo analysis were selected as seeds to calculate static functional connectivity (sFC). We also applied the sliding-window to perform dynamic functional connectivity (dFC). To evaluate the Tuina effect, the mean ReHo and FC values (both static and dynamic) were extracted from significant clusters and compared between LDH and HCs.

Results

In comparison to HCs, LDH patients displayed decreased ReHo in the left orbital part middle frontal gyrus (LO-MFG). For sFC analysis, no significant difference was found. However, we found decreased dFC variance between LO-MFG and the left Fusiform, and increased dFC variance in the left orbital inferior frontal gyrus and left precuneus. Both ReHo and dFC values revealed after Tuina, the brain activities in LDH patients were similar to HCs.

Conclusion

The present study characterized the altered patterns of regional homogeneity in spontaneous brain activity and those of functional connectivity in patients with LDH. Tuina can reshape the function of the default mode network (DMN) in LDH patients, which may contribute to the analgesic effect of Tuina in LDH patients.

Ultrasound-guided Jamshidi needle puncture to reduce radiation exposure during percutaneous pedicle screw placement: study protocol for a randomised controlled trial

INTRODUCTION

Percutaneous pedicle screw placement (PPSP) is a minimally invasive procedure highly dependent on fluoroscopic guidance, which results in increased radiation exposure and prolonged operative time. Ultrasound can image the lumbar paravertebral anatomy and the needle trajectory in real time, which may help reduce the use of fluoroscopy and radiation dose in PPSP. We will conduct a parallel randomised controlled trial to mainly investigate the effect of ultrasound guidance in radiation reduction during PPSP.

METHODS AND ANALYSIS

A total of 42 patients will be recruited and randomly assigned to the intervention group and the control group at a 1:1 ratio. In the intervention group, we will use ultrasound in combination with fluoroscopy to guide the insertion of the Jamshidi needles. In the control group, PPSP will be performed under conventional fluoroscopic guidance. The primary outcomes are the cumulative fluoroscopy time (s), radiation dose (mGy) and exposure times of screw placement. The secondary outcomes are insertion time of guidewire, rate of pedicle perforation, rate of facet joint violation, visual analogue scale for back pain, Oswestry Disability Index and complications. The participants, outcome assessors and data analysts will be blinded to allocation.

ETHICS AND DISSEMINATION

The trial was approved by the research ethics committee of Shengjing Hospital, China Medical University. The results will be presented at academic seminars and submitted for publication in peer-reviewed journals.This study involves human participants and was approved by Research Ethics Committee of Shengjing Hospital, China Medical University reference number：2022PS704K. Participants gave informed consent to participate in the study before taking part.

Efficacy of Pilates on Pain, Functional Disorders and Quality of Life in Patients with Chronic Low Back Pain: A Systematic Review and Meta-Analysis

BACKGROUND

Chronic low back pain (CLBP) is a common health problem. Pilates is a unique exercise therapy. This meta-analysis aims to evaluate the efficacy of Pilates on pain, functional disorders, and quality of life in patients with chronic low back pain (CLBP).

METHODS

PubMed, Web of Science, CNKI, VIP, Wanfang Data, CBM, EBSCO, and Embase were searched. Randomized controlled trials of Pilates in the treatment of CLBP were collected based on the inclusion and exclusion criteria. The meta-analysis was performed using RevMan 5.4 and Stata 12.2.

RESULTS

19 randomized controlled trials with a total of 1108 patients were included. Compared with the controls, the results showed the following values: Pain Scale [standard mean difference; SMD = -1.31, 95%CI (-1.80, -0.83), p < 0.00001], Oswestry Disability Index (ODI) [mean difference; MD = -4.35, 95%CI (-5.77, -2.94), p < 0.00001], Roland-Morris Disability Questionnaire (RMDQ) [MD = -2.26, 95%CI (-4.45, -0.08), p = 0.04], 36-item Short-Form (SF-36) (Physical Function (PF) [MD = 5.09, 95%CI (0.20, 9.99), p = 0.04], Role Physical (RP) [MD = 5.02, 95%CI (-1.03, 11.06), p = 0.10], Bodily Pain (BP) [MD = 8.79, 95%CI (-1.57, 19.16), p = 0.10], General Health (GH) [MD = 8.45, 95%CI (-5.61, 22.51), p = 0.24], Vitality (VT) [MD = 8.20, 95%CI(-2.30, 18.71), p = 0.13], Social Functioning (SF) [MD = -1.11, 95%CI (-7.70, 5.48), p = 0.74], Role Emotional (RE) [MD = 0.86, 95%CI (-5.53, 7.25), p = 0.79], Mental Health (MH) [MD = 11.04, 95%CI (-12.51, 34.59), p = 0.36]), Quebec Back in Disability Scale (QBPDS) [MD = -5.51, 95%CI (-23.84, 12.81), p = 0.56], and the sit-and-reach test [MD = 1.81, 95%CI (-0.25, 3.88), p = 0.09].

CONCLUSIONS

This meta-analysis reveals that Pilates may have positive efficacy for pain relief and the improvement of functional disorders in CLBP patients, but the improvement in quality of life seems to be less obvious.

Management of lumbar spinal stenosis: a systematic review and meta-analysis of rehabilitation, surgical, injection, and medication interventions

BACKGROUND

Lumbar spinal stenosis (LSS) has a substantial impact on mobility, autonomy, and quality of life. Previous reviews have demonstrated inconsistent results and/or have not delineated between specific nonsurgical interventions.

OBJECTIVE

The purpose of this systematic review is to assess the effectiveness of interventions in the management of LSS.

METHODS

Eligible studies were randomized controlled trials (RCTs) or prospective studies, included patients with LSS, assessed the effectiveness of any interventions (rehabilitation, surgical, injection, medication), included at least two intervention groups, and included at least one measure of pain, disability, ambulation assessment, or LSS-specific symptoms. Eighty-five articles met inclusion criteria. Meta-analyses were conducted across outcomes. Effect sizes were calculated using Hedge's g and reported descriptively. Formal grading of evidence was conducted.

RESULTS

Meta-analysis comparing rehabilitation to no treatment/placebo demonstrated significant effects on pain favoring rehabilitation (mean difference, MD -1.63; 95% CI: -2.68, -0.57; I² = 71%; p = .002). All other comparisons to no treatment/placebo revealed nonsignificant findings. The level of evidence ranged from very low to high for rehabilitation and medication versus no treatment/placebo for pain, disability, ambulation ability, and LSS symptoms.

CONCLUSIONS

Although the findings of this review are inconclusive regarding superiority of interventions, this accentuates the value of multimodal patient-centered care in the management of patients with LSS.

Self-reported physical function is strongly related to pain behavior and pain interference and weakly related to physical capacity in people with chronic low back pain

BACKGROUND

Inclusion of self-reported and capacity-based measures may help to further elucidate the interactive link between how people think and move.

OBJECTIVE

To characterize the relationship between self-reported factors of physical function and pain with objective physical capacity measures.

DESIGN

Cross-sectional study of 328 adults with chronic low back pain (CLBP).

METHOD

Spearman correlations assessed the relationship between pairs of measures. Multiple linear regression models assessed the association between self-reported measures of physical function and the grouping of physical capacity measures. Self-reported measures included Roland Morris Disability Questionnaire (RMDQ), PROMIS Physical Function, Pain Behavior, and Pain Interference; Fear-Avoidance Beliefs Questionnaire (FABQ), Pain Catastrophizing Scale (PCS), and Chronic Pain Acceptance Questionnaire (CPAQ). Capacity measures included walking speed and endurance, lower extremity functional strength, lumbopelvic range of motion, and trunk endurance.

RESULTS

PROMIS Physical Function was directly and weakly correlated with walking speed (ρ = 0.26, 2-min walk) and inversely and weakly correlated with lower extremity strength (ρ = -0.29, 5x sit-to-stand). RMDQ was not correlated with any of the capacity-based measures. PROMIS Physical Function was inversely and moderately correlated with Pain Interference (ρ = -0.48) and Pain Behavior (ρ = -0.43), PCS (ρ = -0.36), and FABQ (ρ = -0.31). The RMDQ was strongly correlated with PROMIS Physical Function (ρ = -0.56), Pain Behavior (ρ = 0.51) and Pain Interference (ρ = 0.49); and moderately correlated with PCS (ρ = 0.37) and FABQ (ρ = 0.33). PROMIS Physical Function and RMDQ were not correlated with CPAQ. Lower scores on PROMIS Physical Function were weakly associated with lower measures of lower extremity strength (-0.30, 95% CI: -0.51 to -0.09, p = 0.005). Higher scores on RMDQ were also weakly associated with lower measures of lower extremity strength (0.26, 95% CI: 0.11 to 0.41, p = 0.001).

CONCLUSIONS

A strong association emerged between self-reported limitations in physical function, pain behavior, and pain interference. A weak association emerged between self-reported physical function and lower extremity strength.

Long-term effects of deep-learning digital therapeutics on pain, movement control, and preliminary cost-effectiveness in low back pain: A randomized controlled trial

Objective

The present study aimed to compare the effects of a deep learning-based digital application with digital application physical therapy (DPT) and those of conventional physical therapy (CPT) on back pain intensity, limited functional ability, lower extremity weakness, radicular symptoms, limited range of motion (ROM), functional movement, quality of life, cost-effectiveness, and postintervention questionnaires for perceived transmission risk of COVID-19 and satisfaction results in 100 participants with low back pain (LBP).

Methods

One hundred participants with LBP were randomized into either DPT or CPT groups, three times per week over four weeks. Outcome measures included the (1) Oswestry Disability Index, (2) Quebec Back Pain Disability Scale, (3) Roland-Morris Disability Questionnaire (RMDQ), (4) Numeric Pain Rating Scale, (5) functional movement screen (FMS), (6) short form-12, (7) lower extremity strength, (8) ROM of trunk flexion, extension, and bilateral side bending, (9) questionnaires for perceived transmission risk of COVID-19, (10) preliminary cost-effectiveness, and (11) postintervention satisfaction questionnaire results. The analysis of variance was conducted at p < 0.05.

Results

Analysis of variance showed that DPT showed superior effects, compared to CPT on RMDQ, hip extensor strength, transmission risk of COVID-19, as well as satisfaction. Both groups showed significant improvement pre- and postintervention, suggesting that DPT is as effective as CPT, and was superior in preliminary cost-effectiveness and transmission risk of COVID-19.

Conclusions

Our results provide novel, promising clinical evidence that DPT was as effective as CPT in improving structural and functional impairment, activity limitation, and participation restriction. Our results highlight the successful incorporation of DPT intervention for clinical outcome measures, lower extremity strength, trunk mobility, ADL improvement, QOL improvement, and FMS in LBP.

Effectiveness of polarized polychromatic light therapy on myofascial trigger points in chronic non-specific low back pain: a single blinded randomized controlled trial

Background

Phototherapy has been used for the treatment of chronic low back pain. However, the effect of linear polarized polychromatic light (PL) has not been examined on myofascial trigger points in patients with chronic non-specific low back pain (NSLBP).

Objectives

To investigate the effectiveness of PL on pain intensity, pain sensitivity of active myofascial trigger points (MTrPs) in gluteus medius (GM) and quadratus lamborum (QL) muscles, back disability, and lumbar range of motion in chronic NSLBP.

Methods

Forty-two participants of both genders with chronic NSLBP were randomly allocated into two equal groups: group A (Linear polarized polychromatic light (PL): 21 participants received polarized light therapy in the range of red and near-infrared rays on myofascial trigger points of bilateral GM and QL muscles for 5 min/point followed by stretching and strengthening exercises for 4 weeks. Group B (Sham PL): 21 participants received the same program but with sham linear polarized polychromatic light therapy. Numeric pain rating scale, pressure algometer, and Roland-Morris Disability Questionnaire were used to measure pain intensity, pain sensitivity (as represented by pain pressure threshold (PPT) of MTrPs of the target muscles and back disability respectively. Further, lumbar flexion, extension, and bilateral rotation were examined with a tape measure, while bilateral side bending were examined with a universal goniometer.

Results

After the intervention program, significant improvements (p < 0.05) in pain intensity, PPT of MTrPs of left GM (Effect Size (ES): 1.23) and bilateral QL muscles (ES Rt QL: 0.9; Lt QL: 1.56) were found in group A in comparison with group B. Nevertheless, the two groups displayed similar improvements (p > 0.05) in lumbar range of motion and back disability.

Conclusion

Linear polarized polychromatic light therapy in the range of red and near-infrared rays improves pain intensity and pain sensitivity of myofascial trigger points in chronic NSLBP.

Differences in balance control despite self-reported resolution of pregnancy-related pelvic girdle pain. A cross-sectional study

BACKGROUND

Motor control patterns are altered when women with pregnancy-related pelvic girdle pain (PGP) experience pain. In low back pain, these adaptations can persist after recovery.

OBJECTIVES

This study aimed to assess balance control in postpartum women with and without a history of PGP during pregnancy.

DESIGN

Cross-sectional study.

METHOD

Eighteen postpartum women who reported to be recovered from PGP, and twelve postpartum women without a history of PGP during pregnancy performed two clinical tests: the single leg stance and active straight leg raise test. Primary outcomes were ground reaction forces measured with a force platform.

RESULTS

Multiple linear regression analyses showed smaller lateral displacement (β = -11cm; 95%CI: 19 to -3; p = 0.008) and lower displacement velocity of the Centre of Pressure (COP) (Ratio of Geometric Means (RGM) 0.76; 95%CI: 0.59 to 0.99; p = 0.043) during single leg stance in the participants with a history of PGP compared to participants without a history of PGP. Push-off force (β = -4.8 N; 95%CI: 22.0 to 12.5; p = 0.57) and asymmetry of push-off force (RGM 1.77; 95%CI: 0.62 to 5.04; p = 0.27) did not differ between groups. During the active straight leg raise test, no differences in lateral displacement (β = 3 cm; 95%CI: 3 to 8; p = 0.30) and COP displacement velocity (RGM 1.03; 95%CI: 0.70 to 1.52; p = 0.87) were observed.

CONCLUSIONS

Although the women with a history of PGP considered themselves recovered, their balance control during single leg stance was poorer compared to those without a history of PGP. No differences were found during the active straight leg raise test.

Determination of Patient Acceptable Symptom State for the Oswestry Disability Index Score in Patients Who Underwent Minimally Invasive Discectomy for Lumbar Disc Herniation: 2-Year Follow-up Data from a Randomized Controlled Trial

OBJECTIVE

We aim to determinate the patient acceptable symptom state (PASS) for the Oswestry Disability Index (ODI) score in patients undergoing minimally invasive discectomy for the treatment of lumbar disc herniation.

METHODS

A post hoc analysis of prospectively collected, 2-year follow-up data was conducted. The anchor for determination of PASS was the European Quality of Life Visual Analog Scales question, and the Pearson correlation test was performed to evaluate its validity. The receiver operating characteristics (ROC) curve analysis was conducted to determine the PASS thresholds for ODI and its discriminative ability assessment. Sensitivity analyses were also carried out for alternative definition of PASS, different follow-up periods, and different subgroups.

RESULTS

A total of 222 patients (92.1%) completed the 2-year follow-up, 92.8% of whom considered their state to be acceptable. The area under the ROC curve (AUC) were all >0.8, indicating a high discriminative ability. The PASS threshold for the ODI was suggested to be 5 at 6 months (AUC: 0.80; sensitivity: 79.0%, specificity: 73.7%) and 2 years (AUC: 0.98; sensitivity: 90.3%, specificity: 100%) postoperatively. Despite some variations found in different body mass index and baseline ODI subgroups, sensitivity analysis showed that the above-mentioned threshold was robust.

CONCLUSIONS

An ODI of 5 was noted to be the PASS threshold for patients received minimally invasive discectomy for the treatment of LDH. This ODI threshold was robust, and therefore recommended as the ultimate goal of minimally invasive treatment for LDH, which can help to present results of clinical research at an individual level.

Associations Between Gluteus Medius Trigger Points With Hip Passive Range of Movement and Muscle Strength in Adults With Chronic Nonspecific Low Back Pain: A Cross-Sectional Study

OBJECTIVE

The purpose of this study was to investigate whether there is a relationship between gluteus medius trigger points with hip passive range of motion and hip muscle strength in people with chronic nonspecific low back pain (LBP).

METHODS

This was a cross-sectional, blinded study that took place in 2 rural communities in New Zealand. Assessments were carried out in physiotherapy clinics in these towns. A total of 42 participants over 18 years old experiencing chronic nonspecific LBP were recruited. After meeting inclusion criteria, participants completed the following 3 questionnaires: Numerical Pain Rating Scale, Oswestry Disability Index, and Tampa Scale of Kinesiophobia. The primary researcher (a physiotherapist) assessed each participant's bilateral hip passive range of movement (using an inclinometer) and muscle strength (using a dynamometer). Following this, a blinded trigger point assessor examined the gluteus medius muscles for the presence of active and latent trigger points.

RESULTS

General linear modeling using univariate analysis revealed that there was a positive association between hip strength and trigger point status (P =.03 left internal rotation, P =.04 right internal rotation, and P =.02 right abduction). Participants with no trigger points showed higher strength values (eg, right internal rotation standard error: 0.64), and those with trigger points showed lower strength. Overall, muscles exhibiting latent trigger points were the weakest (eg, right internal rotation standard error: 0.67).

CONCLUSION

The presence of active or latent gluteus medius trigger points was associated with hip weakness in adults with chronic nonspecific LBP. There was no association between gluteus medius trigger points and hip passive range of movement.

Outcomes With a Mobile Digital Health Platform for Patients Undergoing Spine Surgery: Retrospective Analysis

BACKGROUND

Digital health solutions have been shown to enhance outcomes for individuals with chronic medical illnesses, but few have been validated for surgical patients. The digital health platform ManageMySurgery (MMS) has been validated for spine surgery as a feasible method for patients along their surgical journey through in-app education and completion of patient-reported outcomes surveys.

OBJECTIVE

The aim of this study is to determine the rates of 90-day emergency room (ER) visits, readmissions, and complications in patients undergoing spine surgery using MMS compared to patients using traditional perioperative care alone.

METHODS

Patients undergoing spine surgery at a US-based academic hospital were invited to use MMS perioperatively between December 2017 and September 2021. All patients received standard perioperative care and were classified as MMS users if they logged into the app. Demographic information and 90-day outcomes were acquired via electronic health record review. The odds ratios of having 90-day ER visits, readmissions, mild complications, and severe complications between the MMS and non-MMS groups were estimated using logistic regression models.

RESULTS

A total of 1015 patients were invited, with 679 using MMS. MMS users and nonusers had similar demographics: the average ages were 57.9 (SD 12.5) years and 61.5 (SD 12.7) years, 54.1% (367/679) and 47.3% (159/336) were male, and 90.1% (612/679) and 88.7% (298/336) had commercial or Medicare insurance, respectively. Cervical fusions (559/1015, 55.07%) and single-approach lumbar fusions (231/1015, 22.76%) were the most common procedures for all patients. MMS users had a lower 90-day readmission rate (55/679, 8.1%) than did nonusers (30/336, 8.9%). Mild complications (MMS: 56/679, 8.3%; non-MMS: 32/336, 9.5%) and severe complications (MMS: 66/679, 9.7%; non-MMS: 43/336, 12.8%) were also lower in MMS users. MMS users had a lower 90-day ER visit rate (MMS: 62/679, 9.1%; non-MMS: 45/336, 13.4%). After adjustments were made for age and sex, the odds of having 90-day ER visits for MMS users were 32% lower than those for nonusers, but this difference was not statistically significant (odds ratio 0.68, 95% CI 0.45-1.02; P=.06).

CONCLUSIONS

This is one of the first studies to show differences in acute outcomes for people undergoing spine surgery who use a digital health app. This study found a correlation between MMS use and fewer postsurgical ER visits in a large group of spine surgery patients. A planned randomized controlled trial will provide additional evidence of whether this digital health tool can be used as an intervention to improve patient outcomes.

Patient adherence to physical activity advice (PAPA) in patients with low back pain: Study protocol for a multicentre randomized controlled trial

BACKGROUND

It seems that nonspecific low back pain (NSLBP) cannot be successfully treated with a single intervention of any kind. However, a positive effect of an active lifestyle including physical activities in NSLBP is reported on pain and disability. Advising regular physical activity is one of the mainstays in physical therapy treatment, appealing to patients' adherence. Many patients with low back pain do not seem to adhere to their physiotherapist's advice. In this study, the influence of social support on adherence to an activity advice will be investigated.

OBJECTIVE

Objective of the study is to investigate if patients with low back pain randomised to receive social support adhere better to an activity advice than patients randomised to the control group.

METHODS

In a randomized controlled clinical trial, in private physiotherapy practices in the Netherlands, patients ≥18 years presenting with at least a second episode of nonspecific low back pain will be randomized over two groups: activity advice and social support as an add-on to usual care versus usual care alone. The primary outcome measure is adherence to an activity advice measured by an activity monitor at 1, 6 and 12 weeks. All other objectives will be measured by questionnaires.

DISCUSSION

This project is the first comprehensive research project to assess whether social support influences adherence to an activity advice outside the clinical setting without supervision of a healthcare provider. Where evidence of influence on social support is lacking, findings may have implications for the management of patients with low back pain. In addition, findings may enable physiotherapists to predict in which patients with low back pain an activity advice with social support makes sense.

A spinal manipulative therapy altered brain activity in patients with lumbar disc herniation: A resting-state functional magnetic resonance imaging study

Purpose

Lumbar disc herniation (LDH) is one of the leading causes of low-back pain and results in a series of clinical symptoms, including pain, reflex loss, and muscle weakness. Spinal manipulative therapy (SMT) can relieve pain and promote internal and external stabilization of the lumbar spine. In this study, we investigated whether the brain alterations of LDH patients with SMT were frequency-dependent based on the calculation of Amplitude of Low-Frequency Fluctuations (ALFF) and fractional ALFF (fALFF). Further, we established a cohort of LDH patients to evaluate the contribution of SMT treatments to brain functional reorganization.

Methods

A total of 55 participants, including 27 LDH patients and 28 health controls (HCs), were collected. All LDH patients underwent two fMRI scans (before SMT and after the sixth SMT session). To represent LDH-related brain oscillatory activities, we calculated the ALFF and fALFF in the conventional band (0.01-0.08 Hz), the slow-4 band (0.027-0.073 Hz), and the slow-5 band (0.01-0.027 Hz). Moreover, we extracted ALFF and fALFF values in clusters with significant differences to evaluate the SMT effect.

Results

Compared with HCs, the LDH patients before SMT (LDH-pre) exhibited increased fALFF in right lingual gyri in the conventional band, and showed increased fALFF in left Cerebelum_Crus1 in the slow-4 band. We further examined the abnormal brain activities changes before and after the SMT intervention. The ALFF and fALFF values of LDH-pre group were higher than those of the HCs and LDH-pos groups. After SMT, the increased ALFF and fALFF values were suppressed for patients in conventional band and slow-4 band.

Conclusion

The present study characterized the altered regional patterns in spontaneous neural activity in patients with LDH. Meanwhile, SMT is an effective treatment of LDH, and we supposed that it might have been involved in modulating dysfunctional brain regions which are important for the processing of pain. The findings of the current study may provide new insights to understand pathological mechanism of LDH.

Comparison of the effectiveness of conventional physical therapy and extracorporeal shock wave therapy on pain, disability, functional status, and depression in patients with chronic low back pain

Objectives: The aim of this study was to compare the effectiveness of conventional physical therapy (transcutaneous electrical nerve stimulation, hot pack, and therapeutic ultrasound) and extracorporeal shock wave therapy (ESWT) on pain, disability, functional status, and depression in patients with chronic low back pain (LBP).

Patients and methods: Ninety-one patients with chronic LBP were included in the study and randomized to groups that received ESWT or conventional physiotherapy; of these, 70 completed the study (37 males, 33 females; mean age: 46.4±13.3 years; range, 18 to 65 years). Outcome measures included the Visual Analog Scale, the pressure pain algometer, Oswestry Disability Index (ODI), Health Assessment Questionnaire (HAQ), fingertip-to-floor distance, and the Beck Depression Inventory. The assessments were made before treatment and at the first and 12th weeks after treatment.

Results: Extracorporeal shock wave therapy was more effective than conventional physical therapy in terms of Visual Analog Scale scores, the pressure algometer, ODI, HAQ, and fingertip-to-floor distance at the first and 12th week.

Conclusion: Extracorporeal shock wave therapy is superior to conventional physical therapy in terms of improving pain, spinal mobility, and functional status in patients with chronic LBP.

DANTE Study: The First Randomized, Double-Blind, Placebo and Active-Controlled, Parallel Arm Group Study Evaluating the Analgesic Efficacy and Safety of Dexketoprofen TrometAmol aNd Tramadol Hydrochloride Oral FixEd Dose Combination on Moderate to Severe Acute Pain in Patients with Acute Low Back Pain-Rationale and Design

INTRODUCTION

Despite a wide range of treatment approaches and the availability of treatment recommendations or guidelines, no consensus on the most effective pharmacological therapy of low back pain (LBP) has been reached yet. Therefore, additional clinical evidence, particularly if built upon a rigorous clinical trial design, an evidence-based medication choice, and broader inclusion criteria better acknowledging the heterogeneity and intrinsic variability of LBP is needed. The DANTE study has been designed to comprehensively assess the analgesic efficacy and tolerability of dexketoprofen/tramadol (DKP/TRAM) 75/25 mg in a large cohort of patients with moderate to severe acute LBP.

METHODS

The DANTE study is a phase IV, multicenter, randomized, double-blind, double-dummy parallel group, placebo, and active controlled study. The DANTE study encompasses a single-dose phase (day 1, t0-t8h) and a multiple-dose phase (from t8h to 8 h after intake of last dose at day 5). The DANTE study population includes patients naïve to LBP or patients with previous history of LBP experiencing a new episode of moderate to severe intensity with or without radiculopathy. The clinical phase of the DANTE study started in September 2020 and the anticipated completion date is April 2022.

PLANNED OUTCOMES

The primary endpoint is the time to first achieve a numeric rating scale-pain intensity (NRS-PI) score of < 4 or a pain intensity reduction ≥ 30% from drug intake up to 8 h after the first dose (t8h). Secondary objectives aim are: (1) to evaluate the analgesic efficacy of TRAM/DKP 75/25 mg versus TRAM 100 mg after the first dose; (2) to evaluate the analgesic efficacy of TRAM/DKP 75/25 mg versus TRAM 100 mg after the multiple doses (from t8h until day 5, multiple dose); and (3) to assess the safety and tolerability of the TRAM/DKP 75/25 mg fixed combination after single and multiple doses.

Prevalence and extent of low back pain and low back-related disability in non-care-seeking working-age adults

OBJECTIVE

To explore the prevalence and extent of low back pain (LBP) and low back-related disability in working-age adults not seeking care.

METHODS

A convenience sample of 101 working-age adults not seeking care for LBP completed the Oswestry Disability Index (ODI) and Roland-Morris Disability Questionnaire (RMDQ) as measures of disability and completed questionnaires that collected information on various demographic and health-related variables. Those reporting current LBP also completed a Numeric Pain Rating Scale (NPRS). Prevalence was assessed based on a dichotomization of whether any disability or pain was reported and also as a continuous variable to assess the extent of pain and disability present for each participant.

RESULTS

Of the 101 participants, 72.3% reported some level of disability (ODI mean = 7.91%, RMDQ mean = 2.63) and 46.5% reported some level of pain (NRPS mean = 3.68). Previous care-seeking for LBP was associated with increased odds of reporting disability (ODI odds ratio [OR] 7.91, 95% confidence interval [CI], 2.43 to 31.18; RMDQ OR 2.69, 95% CI, 1.05 to 7.24), as was reporting any current LBP (ODI OR 9.45, 95% CI, 3.15 to 33.21; RMDQ OR 7.03, 95% CI, 2.82 to 18.89). No other demographic or health-related variables were associated with the presence or extent of pain or disability.

CONCLUSION

Many non-care-seeking individuals reported some level of LBP and/or disability, suggesting that some level of pain and disability may be considered normal, acceptable, or manageable. One-third of individuals with no pain reported some disability.

Psychosocial factors associated with disability in patients with non-specific chronic low back pain: A cross-sectional study

INTRODUCTION AND OBJECTIVES

Chronic low back pain is the main cause of disability worldwide, generating high costs for society. To evaluate the prevalence of disability in patients with non-specific chronic low back pain and associated factors, including the impacts of low back pain and psychosocial factors linked to kinesiophobia, catastrophism, anxiety, and depression.

PATIENTS

A cross-sectional study was carried out with 108 adult individuals who had non-specific chronic low back pain. The patients answered previously validated questionnaires, namely the Brief Pain Inventory, the Roland-Morris Disability Questionnaire, the Pain Catastrophizing Scale, the Tampa Kinesiophobia Scale, and the Hospital Anxiety and Depression Scale.

RESULTS

The prevalence of disability observed was 65.7%, with the mean disability score being 15.7±5.3 points in the Roland-Morris Disability Questionnaire. Although pain intensity and other domains of the Brief Pain Inventory, like anxiety, depression, and severe kinesiophobia were significant in the bivariate analyses, they were not associated with disability in the multivariate analysis. Only catastrophic thoughts (prevalence ratio [PR]=1.19; 95% confidence interval [CI]: 1.07-1.32), and the 'walking' domain (PR=1.08; 95% CI: 1.03-1.14) remained statistically associated with disability.

CONCLUSION

Pain catastrophization and impact on gait were associated with disability in individuals with non-specific chronic low back pain. Motor control thoughts and behaviors during functional activities were considered to be relevant aspects for the better assessment and treatment of these patients.

Analysis of Patient-reported Outcomes Measures Used in Lumbar Fusion Surgery Research for Degenerative Spondylolisthesis

STUDY DESIGN

Meta-analyses.

OBJECTIVE

This study aims to document the most common Patient-reported Outcome Measures (PROMs) used to assess lumbar fusion surgery outcomes and provide an estimate of the average improvement following surgical treatment.

SUMMARY OF BACKGROUND DATA

As health care institutions place more emphasis on quality of care, accurately quantifying patient perceptions has become a valued tool in measuring outcomes. To this end, greater importance has been placed on the use of PROMs. This is a systemic review and meta-analysis of randomly controlled trials published between 2014 and 2019 assessing surgical treatment of degenerative spondylolisthesis.

METHODS

A fixed effect size model was used to calculate mean difference and a 95% confidence interval (95% CI). Linear regression was used to calculate average expected improvement, adjusted for preoperative scores.

RESULTS

A total of 4 articles (7 study groups) were found for a total of 444 patients. The 3 most common PROMs were Oswestry Disability Index (ODI) (n=7, 100%), Short-Form-12 or Short-Form-36 (SF-12/36) (n=4, 57.1%), and visual analog scale-back pain (n=3, 42.8%). Pooled average improvement was 24.12 (95% CI: 22.49-25.76) for ODI, 21.90 (95% CI: 19.71-24.08) for SF-12/36 mental component score, 22.74 (95% CI: 20.77-24.71) for SF-12/36 physical component score, and 30.87 (95% CI: 43.79-47.97) for visual analog scale-back pain. After adjusting for preoperative scores, patients with the mean preoperative ODI (40.47) would be expected to improve by 22.83 points postoperatively.

CONCLUSIONS

This study provides a range of expected improvement for common PROMs used to evaluate degenerative spondylolisthesis with the goal of equipping clinicians with a benchmark value to use when counseling patients regarding surgery. In doing so, it hopes to provide a comparison point by which to judge individual patient improvement.

Cross-Cultural Adaptation and Clinimetric Testing of Functional Rating Index (FRI) Outcome Measure into the Arabic Language

Background

The Functional Rating Index (FRI) is a self-report scale widely used to determine the level of disability in low back pain (LBP) populations.

Objectives

This study was aimed at conducting the cross-cultural adaptation of the FRI-Arabic version (FRI-Ar) and testing the clinometric properties of FRI-Ar.

Methods

The cross-cultural adaptation process was used to develop the FRI-Ar. This study included acute and subacute LBP patients. Each patient was asked to complete the questionnaires at three time points: baseline, 24-hour follow-up, and two-week follow-up. The questionnaires used were FRI-Ar, Roland-Morris Disability Questionnaire (RMDQ), Oswestry Disability Index (ODI), Numerical Pain Rating Scale (NPRS), Global Perceived Effect Scale (GPE), and Patient-Specific Functional Scale (PSFS). Statistical analysis was carried out to measure the instrument's reliability, validity, and responsiveness.

Results

The FRI was cross-culturally adapted to the Arabic language, and the adapted version was validated. Two hundred patients completed the questionnaires at the baseline; however, 120 patients completed the questionnaires at 24-hour and two-week follow-up. Cronbach's alpha, interclass correlation coefficient (ICC_2,1), standard error of measurement (SEM), and minimal detectable change (MDC_95%) for the FRI-Ar were observed as 0.85, 0.85, 1.17 (2.9%), and 3.24, respectively. The FRI-Ar showed a moderate positive correlation only with the RMDQ, ODI, and NPRS (p < 0.05). Also, it showed the responsiveness with a small effect size (ES = 0.29) and standardized response mean (SRM = 0.44).

Conclusion

The FRI-Ar was developed, and it showed good reliability and validity. However, it revealed the responsiveness with the small change. It can evaluate both pain and functional limitations in acute and subacute LBP patients. Before using it in the Arabic population with acute and subacute LBP, it is recommended to conduct further research to test internal and external responsiveness using an external criterion with a more extended follow-up period and suitable interventions.

Association Between Psychosocial Parameters and Response to Chiropractic Care Among Older Adults With Chronic Low Back Pain: Secondary Analysis of a Randomized Clinical Trial

OBJECTIVES

The purpose of this study was to determine whether baseline self-efficacy, fear of pain with movement (kinesiophobia), or change in either were associated with clinically important improvement in disability among older adults with chronic low back pain after 12 weeks of chiropractic spinal manipulation (CSM) and exercise.

METHODS

This secondary analysis used randomized trial data from community-dwelling adults aged 65 years or older with chronic spinal disability who received non-pharmacological treatment of CSM and exercise. Those with ≥30% reduction in the Oswestry Disability Index (ODI) after 12 weeks of treatment were considered responders to care. Psychosocial measures included the Pain Self-Efficacy Questionnaire (PSEQ) and the Tampa Scale of Kinesiophobia (TSK). Logistic regression-assessed associations were between psychosocial, demographic, and low back predictors and 30% ODI improvement.

RESULTS

There were 176 community-dwelling older adults included in this analysis. Mean age was 71 years, 59.7% were women; 176 (96.7%) had complete data. Baseline disability (ODI = 26.1 ± 9.3) and back pain (5.0 ± 1.9, 0-10 scale) were moderate. Baseline PSEQ reflected higher self-efficacy (47.7 ± 7.8, 0-60 scale) with minimal kinesiophobia (TSK 34.3 ± 5.2, 17-68 scale). Seventy-two (40.9%) achieved 30% reduction in ODI (mean -5.4 ± 7.9) after 12 weeks of treatment. Mean self-efficacy improvement was clinically important (2.5 ± 6.5 points); kinesiophobia (-2.7 ± 4.4 points) and LBP (-1.6 points) also improved. Baseline PSEQ and percent improvement in PSEQ and TSK were associated with response to treatment in univariate regression analyses but not in multiple regression models that included low back predictors. LBP duration >4 years negatively impacted recovery.

CONCLUSIONS

Among this sample of older adults who received chiropractic manipulation and exercise, baseline self-efficacy and improvements in self-efficacy and kinesiophobia were individually associated with clinically important reductions in disability post-intervention, although not in adjusted models when LBP duration was included.

Musculoskeletal syndrome treated with global postural re-education in double-redo lung transplantation: a case report with an 8-month follow-up

Postoperative pain and persisting fatigue represent critical concerns for patients receiving lung transplantation. The purpose of this study was to illustrate the trajectory of symptoms in a patient who presented with a posttransplant musculoskeletal syndrome after double redo-lung transplantation and attended therapeutic sessions of global postural re-education during the symptomatic phase. A 32-year-old woman with interstitial lung disease underwent double lung transplantation. At 23 months, functional parameters deteriorated, and the patient was placed on the active list for a second double-lung transplantation. Twenty months after re-transplantation, the patient reported continuous thoracic-lumbar musculoskeletal pain exacerbated by moving or performing the standard motor activities. Lower body flexibility improved during the observation period changed from -10 cm to 0 cm at the Chair Sitand- Reach Test. Leg strength improved as well, and the patient was able to perform more repetitions at the Squat Test, improving from 14 to 39. Pain intensity changed from 7 to 4 on a numerical rating scale. We observed that outcomes strictly related to treatment, with lower body flexibility, pain intensity, and physical function improving over time. As a result global postural re-education proved to be effective in this patient.

Evaluation of MyRelief Serious Game for Better Self-Management of Health Behaviour Strategies on Chronic Low-Back Pain

Low back pain is a leading cause of disability worldwide, putting a significant strain on individual sufferers, their families, and the economy as a whole. It has a significant economic impact on the global economy because of the costs associated with healthcare, lost productivity, activity limitation, and work absence. Self-management, education, and adopting healthy lifestyle behaviors, such as increasing physical activity, are all widely recommended treatments. Access to services provided by healthcare professionals who provide these treatments can be limited and costly. This evaluation study focuses on the application of the MyRelief serious game, with the goal of addressing such challenges by providing an accessible, interactive, and fun platform that incorporates self-management, behavior change strategies, and educational information consistent with recommendations for managing low-back pain, based on self-assessment models implemented through ontology-based mechanics. Functional disability measured using the Oswestry Disability Questionnaire showed the statistically significant (p < 0.001) improvement in subjects’ self-evaluation of their health status. System Usability Scale (SUS) test score of 77.6 also suggests that the MyRelief serious game can potentially influence patient enablement.

Group-based exercice training programs for military members presenting musculoskeletal disorders - protocol for a pragmatic randomized controlled trial

BACKGROUND

Musculoskeletal disorders are a leading cause of morbidity and the most prevalent source of disability among soldiers. Their high prevalence in armed forces and limited ressources have led to problems related to access to physical rehabilitation care. To increase access, supervised group-based exercise programs for the most prevalent musculoskeletal disorders (low back pain, patellofemoral pain, rotator cuff-related shoulder pain or lateral ankle sprain) have been developed at a Canadian Armed forces (CAF) base, but their effectiveness has not been evaluated. The primary objective of this randomized controlled trial is to evaluate the mid- and long-term effects of these group-based training programs on pain severity and functional limitations, in comparison with usual individual physiotherapy care. Secondary objectives include comparing both interventions in terms of health-related quality of life, pain-related fear, and patients' satisfaction.

METHODS

One hundred and twenty soldiers with a new medical referral for physiotherapy services for one of the four targeted musculoskeletal disorders will be consecutively recruited. They will be randomly assigned to either group-based training program or usual individual physiotherapy care, and will take part in the assigned 12-week intervention. There will be four evaluation sessions over 26 weeks (baseline, week 6, 12 and 26). At each follow-up, functional limitations, pain severity, health-related quality of life and pain-related fears will be assessed. Patients satisfaction with treatment will also be evaluated at the end of the intervention period. Either two-way repeated measures ANOVA will be used to analyse and compare the effects of the interventions.

DISCUSSION

This RCT will determine the effectiveness of group-based training programs compared to usual individual physiotherapy care. This new intervention model could represent an efficient, and more pro-active approach to manage a higher number of soldiers with musculoskeletal disorders. It could improve access to physical rehabilitation care and improve the health of soldiers.
