Maternal Parity Effect on Spine Posture Changes and Back Pain During Pregnancy

Background: Pregnancy can significantly alter posture and stability, thereby affecting spine curvatures. A positive relationship between the number of full-term pregnancies and the prevalence of low back pain (LBP) has been reported previously. This study aimed to analyze the impact of pregnancy on spine posture and LBP. Methods: Thirty pregnant females who were nulliparous (Group 1, n = 15) or had one or two pregnancies (Group 2, n = 15) were examined using the photogrammetric method in the first, second, and third trimesters of pregnancy. Further, a correlation analysis was conducted among the body mass index (BMI), pain intensity (VAS scale), and spine posture parameters. Results: The parous groups did not differ significantly in the parameters of the spinal posture. The thoracic angle decreased in trimester II compared to trimester I (157.77° vs. 160.55°, p = 0.004), which, according to the measurement methodology used, means that the thoracic kyphosis curvature increased. BMI was associated with the angle of trunk inclination in trimester I in Group 1 (r = 0.54, p = 0.04), as well as with the thoracic angle in trimesters II and III in Group 2 (r = 0.54–0.62, p < 0.05). A statistically significant correlation between pain intensity and spine posture parameters was more frequently observed in Group 2. Conclusions: Parity does not affect spine posture during pregnancy or pain intensity. The intensity of LBP was associated with spine posture changes during pregnancy, but the character of association differs between groups of parity. Alterations in spine posture should be monitored during pregnancy to prevent back pain.

Effectiveness of Virtual Yoga for Chronic Low Back Pain

Chronic low back pain (CLBP) is a common condition with substantial impact on patients, in the form of physical and emotional suffering; health care costs; productivity; and health care professional burden. Although clinical guidelines recommend use of nonpharmacologic treatments first, such as yoga, there is a gap between guidelines and implementation in clinical practice. To compare the effects of virtual yoga classes vs a wait-list control on CLBP intensity, back-related function, sleep quality, and pain medication use. Single-blinded, 24-week, 2-arm, randomized clinical trial conducted from May 3, 2022, through May 23, 2023, comparing live streamed yoga classes (the yoga now group) with a wait-list control (the yoga later group, in which participants were offered the virtual intervention after the study but without assessments) among adults with CLBP. Adults 18 to 64 years of age with CLBP were recruited from the Cleveland Clinic Employee Health Plan, a large health system self-insured health plan. Inclusion criteria included a mean LBP intensity score of at least 4 on an 11-point numerical rating scale (scores ranged from 0 to 10, with higher scores indicating worse pain) and daily back pain interference about half or more of the days. Twelve consecutive weekly, 60-minute, virtual, live streamed hatha yoga group classes. Coprimary outcomes were mean pain intensity in the previous week on the 11-point numerical rating scale and back-related function as assessed using the 23-point modified Roland Morris Disability Questionnaire ([RMDQ], with higher scores reflecting poorer function) at 12 weeks. Secondary and exploratory outcomes included these measures at 24 weeks, pain medication use, and PROMIS sleep quality assessed using the Sleep Disturbance Short Form 8a, item 1 (scores ranged from 0 to 4, with higher scores reflecting better sleep quality). Analyses followed the intention-to-treat principle. Among 140 participants enrolled (yoga now = 71; yoga later = 69), the mean (SD) age was 47.8 (11.7) years and most were female (113 [80.7%]) and college-educated (103 [73.5%]). Mean (SD) baseline pain intensity (5.7 [1.5]) and RMDQ ([12.1 [4.4]) scores reflected moderate back pain and impairment. At week 12, yoga now compared with yoga later had greater reductions in mean pain intensity (-1.5 [95% CI, -2.2 to -0.7] points; P < .001) and mean RMDQ (-2.8 [95% CI, -4.3 to -1.3] points; P < .001) scores. At 24 weeks, the improvements in pain (mean change, -2.3 [95% CI, -3.1 to -1.6] points; P < .001) and RMDQ (mean change, -4.6 [95% CI, -6.1 to -3.1] points; P < .001) scores were sustained. At 12 weeks, yoga now participants reported 21.4 (95% CI, 5.2-37.6) absolute percentage points less use of any analgesic medication during the past week than yoga later participants and at 24 weeks, 21.2 absolute percentage points (95% CI, 5.2%-37.3%). Improvements in sleep quality were greater for participants in yoga now than among participants in yoga later at 12 weeks (mean change, 0.4 [95% CI, 0.1-0.7] points; P = .008) and 24 weeks (mean change, 0.4 [95% CI, 0.1-0.7] points; P = .005). Results of this randomized clinical trial of 140 adults with CLBP who were members of a large health system self-insured health plan suggest that virtual yoga classes may be a feasible, safe, and effective treatment option.

Postoperative early initiation of sequential exercise program in preventing persistent spinal pain syndrome type-2 after modified transforaminal lumbar interbody fusion: a prospective randomized controlled trial.

This prospective randomized controlled trial aimed to investigate the impact of early postoperative sequential motor control (starting first day post-operatively) and core stabilization training (starting fifth week post-operatively) compared to conventional exercise (starting fifth weeks post-operatively) on the risk of developing persistent spinal pain syndrome type-2 (PSPS-T2). 395 patients with lumbar degenerative diseases (LDDs) undergoing modified transforaminal lumbar interbody fusion and a 12-week postoperative exercise program (sequential vs. conventional exercise: 214 vs. 181) were evaluated for low back pain (LBP) intensity, Oswestry Disability Index (ODI), pressure pain threshold (PPT), temporal summation (TS), fatty infiltration of paraspinal muscles, transversus abdominis (TrA) activation capacity and Fear-Avoidance Beliefs Questionnaire (FABQ) pre-operatively, 3 months post-operatively, and 1 year post-operatively. At 3-month postoperative assessment, LBP in sequential exercise group were lower than those in conventional exercise group (P < 0.05), and sequential-exercise patients had greater local-area PPTs, lower TS, lower TrA activation capacities and less fatty infiltration of erector spinae than did the conventional-exercise patients (P < 0.05). At 1-year postoperative assessment, fewer sequential-exercise patients had PSPS-T2 compared with conventional-exercise patients (11/214 vs. 20/181; P < 0.05). LBP at rest and FABQ were lower in sequential-exercise patients than conventional-exercise patients (P < 0.05). Furthermore, both PPT and TS at 1-year postoperative assessment were associated with these measurements at 3-month postoperative assessment in patients with PSPS-T2 (P < 0.05). Postoperative sequential exercise has more positive effects to avoid PSPS-T2 than conventional exercise in patients with LDDs possibly because of its advantages in improving central and peripheral sensitization.

Relationship of chronic low back pain intensity with functional activity, stress and quality of life in working-age adults

Background. Low back pain (LBP) is a global problem in the modern world. A detailed study of the relationship between pain intensity and the indicators with which it may be associated will allow optimising approaches to the treatment and rehabilitation of patients with chronic LBP. The purpose was to eva­luate the relationship between the intensity of chronic LBP and indicators of functional activity, stress and quality of life in subjects of working age. Materials and methods. A survey was conducted among 159 persons aged 18-65 years with LBP lasting more than 3 months. Using a Google-form, the participants were given a questionnaire that included socio-demographic, anthropometric characteristics, lifestyle data, bad habits, physical activity (PhA) and stress levels, quality of life, and impairment. The intensity of pain was measured at the first visit to a PhRM doctor using a visual analogue scale (VAS). Results. The study involved 159 patients, 65.7 % women and 34.3 % men, with a mean VAS pain intensity of 46.5 ± 18.6 mm. A weak positive correlation was found between pain intensity and age (r = 0.30, p &lt; 0.001), but no significant relationship was found between pain intensity and anthropometric parameters. Subjects who smoke, have insufficient PhA and sleep disturbance had higher pain intensity scores (57.6 ± 15.2 mm (p = 0.04), 49.0 ± 18.8 mm (p = 0.12), 49.7 ± 19.9 mm (p = 0.002), respectively). Sitting time more than 6 hours had significant associations with pain intensity (p &lt; 0.001). A weak positive correlation was found between pain intensity on the VAS scale and stress le­vel (r = 0.24, p = 0.002), a moderate positive correlation between pain intensity and impairment (r = 0.36, p &lt; 0.001) and a mo­derate negative correlation between quality of life and pain intensity. ­Conclusions. There was a significant association between pain intensity and age, smoking, sleep disturbance, sedentary work for more than 6 hours, higher stress levels, impaired functioning and lower quality of life.

Effect of chiropractic care on low back pain for active-duty military members: Mediation through biopsychosocial factors.

This study evaluates biopsychosocial factors as mediators of the effect of chiropractic care on low back pain (LBP) intensity and interference for active-duty military members. Data from a multi-site, pragmatic clinical trial comparing six weeks of chiropractic care plus usual medical care to usual medical care alone for 750 US active-duty military members with LBP were analyzed using natural-effect, multiple-mediator modeling. Mediation of the adjusted mean effect difference on 12-week outcomes of PROMIS-29 pain interference and intensity by 6-week mediators of other PROMIS-29 physical, mental, and social health subdomains was evaluated. The effect difference on pain interference occurring through PROMIS-29 biopsychosocial factors (natural indirect effect = -1.59, 95% CI = -2.28 to -0.88) was 56% (95% CI = 35 to 96) of the total effect (-2.82, 95% CI = -3.98 to -1.53). The difference in effect on pain intensity occurring through biopsychosocial factors was smaller (natural indirect effect = -0.32, 95% CI = -0.50 to -0.18), equaling 26% (95% CI = 15 to 42) of the total effect (-1.23, 95% CI = -1.52 to -0.88). When considered individually, all physical, mental, and social health factors appeared to mediate the effect difference on pain interference and pain intensity with mental health factors having smaller effect estimates. In contrast with effects on pain interference, much of the effect of adding chiropractic care to usual medical care for US military members on pain intensity did not appear to occur through the PROMIS-29 biopsychosocial factors. Physical and social factors appear to be important intermediate measures for patients receiving chiropractic care for low back pain in military settings. Further study is needed to determine if the effect of chiropractic care on pain intensity for active-duty military occurs through other unmeasured factors, such as patient beliefs, or if the effect occurs directly.

Effectiveness of back therapeutic exercises and Pilates on the clinical improvement of the intensity of chronic low back pain and determination of the minimal clinically important improvement threshold from treatments in a hospital setting

The primary aim was to compare the effectiveness of therapeutic back exercises and Pilates in reducing chronic low back pain and to determine the threshold of improvement and the difference in pre- and post-treatment scores considered clinically relevant for patients. Methodology: A total of 53 patients with chronic low back pain were randomly assigned to two groups: one with 27 participants performing Pilates and another with 26 participants following a back exercise program. The treatment consisted of sessions twice a week for three months. Pain intensity was assessed before and after treatment using the Visual Analog Pain Scale. A clinically relevant threshold was defined as a sufficient reduction in pain score for patients to feel "very satisfied." A Receiver Operating Characteristic Curve analysis was used to determine the sensitivity and specificity of the improvement threshold. Additionally, a linear regression model was applied to analyze the relationship between score difference and the percentage of improvement. Results: Although both groups showed significant improvements in pain reduction after treatment, there were no statistically significant differences between them. The average reductions in both groups did not exceed two points (Back Exercise Group = 1.43 points, Pilates Group = 1.82 points), thus not reaching the two-point average improvement required to meet the clinically relevant improvement threshold. However, at an individual level, 45.83% of the Pilates group and 37.5% of the back exercise group achieved a clinically relevant improvement (≥30% improvement). The improvement threshold of 31.4%, equivalent to a two-point reduction, was correlated with greater clinical satisfaction (sensitivity 84%, specificity 87%). Conclusions: Both treatments produced beneficial effects in reducing chronic low back pain. However, the average improvement was not clinically relevant for the overall sample. At an individual level, a significant proportion of patients achieved clinically relevant improvement, particularly in the Pilates group. The 31.4% improvement threshold serves as an additional indicator for evaluating the clinical relevance of treatments. Keywords: Therapeutic back exercises, Pilates, chronic low back pain, Visual Analog Scale for Pain, Minimal Clinically Important Change.

Effect of a smartphone self-management digital support system for low-back pain (selfBACK) among workers with high physical work demands - secondary analysis of a randomized controlled trial.

This study aimed to investigate whether physical work demands modify the effect of the selfBACK app, which is designed to support self-management of low-back pain. In a secondary analysis of the selfBACK trial with 346 employed participants, we stratified into low (N=165) and high physical work demands (N=181). Outcomes included the Roland-Morris Disability Questionnaire (0-24), a numeric rating scale for low-back pain intensity (0-10), the Pain Self-Efficacy Questionnaire (0-60), and work ability (0-10). Intervention effects were assessed at three- and nine-month follow-ups using a linear mixed model. At three months, high physical demand workers with selfBACK showed a significant reduction in pain intensity [-0.8, 95% confidence interval (CI) -1.3- -0.2] compared to usual care. By nine months, the high physical demands workers with selfBACK reported reduced pain-related disability (-1.4, 95% CI -2.7- -0.1), improved pain self-efficacy (3.5, 95% CI 0.9-6.0), and lower pain intensity (-1.0, 95% CI -1.6- -0.4) compared to usual care. Low physical demands workers with selfBACK also improved pain self-efficacy [2.8 (95% CI 0.3-5.3)] compared to usual care. The impact of selfBACK was more noticeable among workers with high physical demands compared to their low physical demand counterparts, but no statistically significant differences were found in any outcome. The selfBACK intervention had consistent effects across workers with high and low physical work demands, indicating that these demands did not modify its impact. Both groups experienced similar positive effects, highlighting the intervention's effectiveness across varying levels of physical work demands.

Effectiveness of Prenatal Gentle Yoga and Effleurage Massage in Low Back Pain Third Trimester Pregnant Women

Background: Pregnant women often complain of low back pain, typically becoming more intense as pregnancy progresses due to changes in posture, such as increased lordosis and a shift in the center of gravity. If not addressed, this pain can negatively impact the quality of life by interfering with daily activities. However, Prenatal gentle yoga and effleurage massage are effective ways to avoid back pain. Objective: To examine how women in their third trimester of pregnancy might manage their lower back discomfort using effleurage massage and gentle yoga. Methods: In the quasi-experimental design of this research, selective sampling approaches are used. Additionally, a two-group pretest-posttest design is utilized, and there is no control group provided. The research was conducted in the PMB Ika Winoto area, and forty expectant mothers with back pain who were in the third trimester were among them. The Effleurage treatment consisted of a 30-minute massage session, with each movement performed for about 10 minutes, administered twice to each participant. Prenatal yoga sessions were also conducted twice a week, with each session lasting 60 minutes. A numerical rating scale, also known as the NRS, was used to assess the amount of back pain that the patient was experiencing). To fully examine the data, a Wilcoxon Signed Rank Test was used. Results: P-values for the Effleurage massage group and the Prenatal Gentle Yoga group were 0.000 and 0.005, respectively, according to the analysis findings. The average reduction in low back pain intensity was 9.86 for the Effleurage massage group and 6.87 for the Prenatal Gentle Yoga group. Conclusion: Both pregnancy gentle yoga and effleurage massage work well to relieve low back pain. Regarding how pregnant women who are still in the third trimester of their pregnancy should be treated for low back pain, the effleurage massage method works better than prenatal yoga. Therefore, for expectant mothers who are suffering from low back discomfort, these techniques represent effective alternative medicines that are simple to use and have few adverse effects.

People With Acute Low Back Pain Have Concerns That May Not Be Addressed by Guideline-Recommended Advice: A Mixed-Methods Study.

OBJECTIVE: To investigate what concerns people with acute low back pain (LBP) and explore whether demographic and clinical factors were associated with having concerns about LBP. DESIGN: Mixed-methods study. METHODS: We included participants aged ≥18 years with acute LBP (LBP≤6 weeks). We collected demographic and clinical characteristics via an online survey and asked one open-ended question to elicit participants' concerns about their LBP. We investigated concerns about LBP using inductive content analysis. Using multivariable logistic regression, we explored associations between demographic and clinical characteristics and having concerns about LBP. RESULTS: We included 2025 participants, a majority of whom (n = 1200, 59.3%) reported having at least 1 concern about their LBP. There were 34 unique concerns, which mapped to 5 themes: causes of LBP (n = 393, 19.4%), future consequences of LBP (n = 390, 19.3%), psychosocial consequences of LBP (n = 287, 14.2%), physical consequences of LBP (n = 210, 10.4%), and health consequences of LBP (n = 84, 4.2%). Demographic and clinical characteristics were associated with having concerns about LBP: participants with university education, having previously received advice for LBP, with higher LBP intensity, interference, and higher anxiety symptoms were more likely to have concerns about their LBP. CONCLUSION: Most people with acute LBP had at least 1 concern about their LBP, more commonly centered around the causes of and the future consequences of LBP.

Work-Related Fear-Avoidance Beliefs and Risk of Low-Back Pain: Prospective Cohort Study Among Healthcare Workers.

Low-back pain (LBP) is a prevalent condition among healthcare workers, negatively affecting well-being and work ability. Research has identified fear-avoidance beliefs, i.e., the belief that physical activities worsen or prolong pain, as a key psychological factor in LBP. Given the physical demands of healthcare work, understanding the link between fear-avoidance and LBP is crucial for effective prevention and management strategies. This study investigated the prospective association between fear-avoidance beliefs and risk of increased LBP intensity and duration in hospital workers. Fear-avoidance beliefs and LBP were assessed in 1933 healthcare workers from 389 departments at 19 hospitals at baseline and 1-year follow-up. Associations between baseline work-related fear-avoidance beliefs (FABW) and LBP intensity and duration at follow-up were analyzed using cumulative logistic regression, adjusting for various factors including age, sex, baseline LBP, education, seniority, patient transfers, psychosocial work environment, and lifestyle. Moderate and high FABW was associated with higher odds of increased pain intensity (OR: 1.37 [95% CI 1.09-1.73] and 1.85 [95% CI 1.18-2.88], respectively) and prolonged pain duration (OR: 1.37 [95% CI 1.05-1.78] and 2.27 [95% CI 1.50-3.44], respectively). A sensitivity analysis including only female nurses showed similar results, with the high FABW group having significantly higher odds of increased pain intensity (OR 2.95, 95% CI 1.84-4.72) and duration (OR 2.64, 95% CI 1.55-4.49). Fear-avoidance beliefs increase the risk of LBP intensity and duration among healthcare workers, emphasizing the need for interventions dealing with psychological aspects of LBP.

Effectiveness of biobehavioral therapeutic education in chronic low back pain intensity and disability: a systematic review

Background: Chronic low back pain (CLBP) is a prevalent musculoskeletal issue that could lead to significant disability. CLBP involves persistent pain and psychological factors contributing to its complexity. Therapeutic education combining cognitive-behavioral approaches may aid in managing CLBP. Objectives: This systematic review evaluates the efficacy of therapeutic education based on a biobehavioral approach in modifying beliefs and promoting active coping strategies in CLBP patients. Methods: Following PRISMA guidelines, we searched PubMed, EBSCO host, and Google Scholar for randomized controlled trials (RCTs) and quasi-experimental studies from March 27 to April 16, 2022, with an update on June 15, 2024. Inclusion criteria focused on adults with CLBP undergoing therapeutic education aimed at behavioral modification. Methodological quality was assessed using the PEDro scale, and risk of bias was evaluated using RoB 2.0. Results: Out of 532 studies, four met the inclusion criteria. The interventions combined therapeutic education with therapeutic exercise or conventional physical therapy. Pain intensity and disability were the main outcomes measured. One study found significant improvements in pain and disability, while others showed trends towards improvement without statistical significance. The quality of evidence was very low. Conclusion: Combining therapeutic education with active coping strategies and other therapies may reduce pain intensity and disability in CLBP patients. However, the evidence quality is very low, highlighting the need for further research.

Meta Analysis: Effects Of Mckenzie Exercise And Other Treatment Techniques In Reducing Pain and Disability In Chronic Nonspecific Low Back Pain

Background Low back pain (LBP) is rising globally due to increase in population and ageing. In adults below 45 years of age, work-related injury leads to nonspecific pain resulting in disability. Exercise therapy has proven to be effective in reducing pain and associated disability in these patients. McKenzie exercises focus on repeated end-range movement and posture correction, thereby reducing pain and disability. This study aims to compare the effectiveness of McKenzie exercise with other techniques in reducing pain and disability in nonspecific chronic LBP (NSCLBP). Objectives To compare the effect of alternate treatment approaches and McKenzie exercises in nonspecific chronic low back pain. Methods Studies that satisfied the inclusion and exclusion criteria for the review were found by searching databases like Google Scholar, Pub Med and Cochrane CENTRAL. This study comprised randomized controlled trials that compared McKenzie treatment with other therapeutic approaches for treating NSCLBP. Two independent reviewers extracted the data and evaluated the trials' quality. Forest plots were used to display the results. Results Eleven full-text articles were included in this study for review in order to conduct a meta-analysis and qualitative analysis. The meta-analysis of pain and functional impairment related to back pain comprised ten studies each. When comparing patients undergoing McKenzie treatment to other treatment techniques, there was a slight overall decrease in the intensity of low back pain (SMD: -0.83 [95% CI: -1.11, -0.55], I2= 80.8%; p&lt; 0.000). After doing McKenzie exercises, low back patients' functional impairment did not improve in comparison to other therapy methods (SMD: 0.07 [95% CI: -0.54, 0.68], I2= 71.5%; p&lt; 0.000). Conclusion McKenzie exercise is equally effective to other manual therapy techniques but slightly effective than passive treatments in decreasing pain &amp; disability in NSCLBP.

Changes in isokinetic trunk muscle strength and endurance after two different restoration programs in people with chronic low back pain: A longitudinal retrospective study

BackgroundMultidisciplinary functional restoration programs (FRPs) aim to improve pain and function in people with chronic low back pain (CLBP). The intensity and content of FRPs varies; the benefits of one program over another are unclear. ObjectiveTo assess changes in trunk muscle strength and endurance after an intensive (IFRP) (for people on sick leave for >6 months with high levels of fear-avoidance beliefs about physical activity and work) or semi-intensive (SIFRP) (for people working) FRP in people with CLBP. MethodsLongitudinal retrospective study from March 2016 to December 2019. Setting: rehabilitation department of a tertiary care center. Trunk flexor and extensor muscle strength (60°.s−1) and endurance (120°.s−1) were measured with the Humac NORM isokinetic dynamometer at pre and post FRP. Change in isokinetic variables (peak torque, total work and flexor/extensor ratio) after each program was assessed with a paired t-test (p < 0.05). Pearson's rho and multiple linear regression assessed associations between changes in isokinetic and clinical variables and demographic characteristics. Results125 individuals, 63.2 % female, age 43.5 (10.3) years, were included. Mean low back pain intensity was 49.8 (24.9) and 37.2 (25.8)/100 and mean activity limitation (QBPDS) was 38.8 (16.4) and 32.0 (14.6)/100 in the IFRP and SFRP groups, respectively. Trunk extensor peak torque, flexor total work, extensor total work and flexor/extensor peak ratio improved significantly in both FRPs, p < 0.001. The flexor/extensor total work ratio improved in the IFRP group only, p = 0.003. Trunk extensor endurance increased more in the IFRP than the SIFRP group, the absolute pre-post differences for extensor total work [95%CI] N.m were 611.7 [495.2; 728.3] in the IFRP group and 380.0 [300.8; 459.3] in the SIFRP group. No variables were correlated and none predicted improvement in extensor total work in either group. ConclusionThis study highlights the short-term independence of clinical and trunk muscle strength and endurance changes.

Characteristics and outcomes of patients with low back pain with and without radiating leg pain following the GLA:D back program

BackgroundSome patients with low back pain (LBP) also report radiating leg pain which is a prognostic factor for poorer clinical outcomes. We aimed: 1) to compare the baseline characteristics of patients with LBP with - (LBP + leg pain) and without radiating leg pain (LBP - alone); 2) to investigate whether patients with LBP + leg pain show similar post-treatment outcomes as compared to LBP – alone, after participation in an exercise and patient education program, i.e. the GLA:D Back program. MethodsThe patient sample included 3508 patients in the GLA:D Back program between March 2018 and August 2022. The outcomes were mean changes in LBP intensity, back-related activity limitation, self-efficacy and fear of movement measured from baseline to 3, 6 and 12 months. Baseline characteristics were compared with descriptive statistics, and linear mixed models were used to estimate group differences in changes from baseline to 3-, 6- and 12 months. Results1915 (55%) of the patients were in the group LBP- alone and 1593 (45%) in the LBP + leg pain. The LBP + leg pain group displayed higher STarT back classification (greater risk of chronicity) compared to the LBP–alone. The LBP + leg pain group showed almost similar improvements in all outcomes compared to LBP – alone after the GLA:D Back program. ConclusionIn long-lasting (chronic) LBP patients, the LBP + leg pain group improved to the same extent as LBP - alone regarding LBP intensity, disability, and fear of movement following an exercise and patient education program, GLA:D Back.

Monoclonal antibodies as analgesia of chronic low back pain: a systematic review and meta-analysis of efficacy and safety

Introduction. Monoclonal antibodies (mAb) emerged as a possible option in addressing the partial response to current treatment modalities in chronic low back pain (CLBP). Objective: to evaluate the efficacy and safety of mAb for CLBP. Materials and Methods. Randomized controlled trials on adult patients with CLBP who received mAb-therapy compared to those who did not as a control group. The result was the changes in Low Back Pain Intensity (LBPI) Numeric Rating Score and Roland–Morris Disability Questionnaire (RMDQ) indicating improved pain, disability, and the risk of adverse events. Meta-analysis, risk of bias, and confidence in the evidence for each analysis were assessed. We aimed at reviewing current treatment methods for degenerative lumbosacral spinal stenosis with an emphasis on surgical treatment methods. Results. Six studies were included, with a total of 3851 participants. mAb significantly reduce LBPI and RMDQ score (weighted mean difference –1.48; 95% CI –2.63 to –0.33; p = 0.01). Tanezumab and fasinumab were significantly reduced both LBPI (weighted mean difference of –4.11; 95% CI –6.27 to –1.95; p = 0.0002 and weighted mean difference –0.24; 95% CI –0.47 to –0.02; p = 0.04 respectively) and RMDQ scores (weighted mean difference –3.72; 95% –5.48 to –1.97 and weighted mean difference –0.50; 95% –0.73 to –0.26 respectively, both p 0.0001). The mAb have significantly greater odds of any adverse events (OR 1.23; 95% 1.06 to 1.43; p = 0.007) but no greater odds regarding serious adverse events (OR 1.00; 95% 0.69 to 1.46; p = 0.98). Conclusion. Depending on the types of drugs used, mAb had a favorable outcome and were relatively safe in reducing LBPI and RMDQ scores.

Pain trajectories over 12 months following conservative care consultation in patients with lumbar spinal stenosis

ObjectiveTo investigate symptom trajectories in chiropractic patients with lumbar spinal stenosis (LSS).MethodsPatients diagnosed with LSS were recruited from chiropractic clinics and self-reported questionnaires were collected at baseline and 1-year follow-up. Patients received weekly text messages about low back pain (LBP) and leg symptoms for 1 year. Group-based trajectory modelling was performed to identify symptom trajectory groups. The groups were compared based on patient characteristics, LBP and leg pain intensity, Oswestry Disability Index (ODI) and Zurich Claudication Questionnaire (ZCQ).ResultsA total of 90 patients were included in the analysis. A three-group trajectory model was chosen: ‘improving’ (16%), ‘fluctuating/improving’ (30%), and ‘persistent’ (54%). The ‘persistent’ group had a higher proportion of women [71% (95% CI 57–82%)] than the ‘improving’ group 29% (95% CI 11–56%), and a higher ODI score at both baseline [34.2 (95% CI 29.7–38.8) vs. 22.8 (16.4–29.1)] and 1-year follow-up [28.1 (95% CI 23.2–33.0) vs. 4.8 (0.1–9.4)]. Similar differences were observed for ZCQ symptom and function scores.ConclusionsPain symptoms in people with LSS followed distinctly different trajectories. Half of the sample had a pattern of consistently severe symptoms over a year, while the other half either improved rapidly or experienced fluctuating symptoms with some improvement.

Surgical treatment of refractory low back pain using implanted BurstDR spinal cord stimulation (SCS) in a cohort of patients without options for corrective surgery: Findings and results from the DISTINCT study, a prospective randomized multi-center-controlled trial

Background: Low back pain (LBP) is a highly prevalent, disabling condition affecting millions of people. Patients with an identifiable anatomic pain generator and resulting neuropathic lower extremity symptoms often undergo spine surgery, but many patients lack identifiable and/or surgically corrective pathology. Nonoperative treatment options often fail to provide sustained relief. Spinal cord stimulation (SCS) is sometimes used to treat these patients, but the lack of level 1 evidence limits its widespread use and insurance coverage. The DISTINCT RCT study evaluates the efficacy of passive recharge burst SCS compared to conventional medical treatment (CMM) in alleviating chronic, refractory axial low back pain. MethodsThis prospective, multicenter, randomized, study with an optional 6-month crossover involved patients who were not candidates for lumbar spine surgery. The primary and secondary endpoints evaluated improvements in low back pain intensity (NRS), back pain-related disability (ODI), pain catastrophizing (PCS), and healthcare utilization. Patients were randomized to SCS therapy or CMM at 30 US study sites. ResultsThe SCS arm reported a 85.3% NRS responder rate (≥ 50% reduction) compared to 6.2% (5/81) in the CMM arm. After the 6M primary endpoint, SCS patients elected to remain on assigned therapy and 66.2% (49/74) of CMM patients chose to trial SCS (crossover). At the 12M follow-up, SCS and crossover patients reported 78.6% and 71.4% NRS responder rates. Secondary outcomes indicated significant improvements in ODI, PCS, and reduced healthcare utilization. Six serious adverse events were reported and resolved without sequelae. ConclusionDISTINCT chronic low back pain patients with no indication for corrective surgery experienced a significant and sustained response to burst SCS therapy for up to 12 months. CMM patients who crossed over to the SCS arm reported profound improvements after 6 months. This data advocates for a timely consideration of SCS therapy in patients unresponsive to conservative therapy.

Early and midterm efficacy of oxiplex gel on postoperative pain intensity, physical disability, and musculoskeletal power in patients undergoing lumbar discectomy

IntroductionCarboxymethylcellulose/polyethylene oxide, also known as Oxiplex gel, is commonly used during lumbar discectomy operations. It serves to cover the surgical site, preventing adhesions and providing relief from pain and symptoms. However, there is ongoing debate regarding the extent of its beneficial effects on postoperative pain intensity, level of disability, and overall improvement of musculoskeletal conditions. Therefore, the objective of this study is to evaluate the advantages and limitations of using Oxiplex gel in lumbar laminectomy procedures specifically for herniated discs.MethodsA randomized controlled trial was conducted on 56 consecutive patients who were candidates for unilateral lumbar discectomy on one lumbar surface. The patients were chosen based on their clinical manifestations and imaging findings. After the initial assessment, the patients underwent either laminectomy or laminotomy surgery. Following the surgery, the patients were randomly assigned to either the intervention group (receiving Oxiplex gel) or the control group. This assignment was done using a computerized random number generator. Assessments were conducted before the operation, as well as 3 and 6 months post-surgery for all patients.ResultsThere was no significant difference found between the Oxiplex gel and control groups in terms of radicular and low back pain intensity, as well as disability scores, at different time points after surgery (p = 0.336, p = 0.65, and p = 0.336, respectively). Additionally, there were no significant differences found in the prevalence of sexual or sphincteric disorders between the two groups during postoperative assessments (p = 0.639 and p = 0.15, respectively). Furthermore, no significant differences were observed in the results of the postsurgical neuromuscular evaluation under different lower extremities conditions between the two groups.ConclusionsBased on our findings, it was observed that Oxiplex gel did not demonstrate any improvement in post-unilateral lumbar discectomy symptoms or musculoskeletal power.
